Primarch

"Man must become stronger, more profound and more evil."

– Friedrich Nietzsche, Thus Spoke Zarathustra: A Book for All and None

"According to the word of God, the meek would someday inherit the earth. Someday. But God never accounted for the mighty."

– Norman McCay, Kingdom Come

The Primarchs were the twenty (-one) genetically-engineered sons of the Emperor. Using his own DNA in their creation, the Primarchs were designed to be far superior to even ~~Space Marines~~ the Adeptus Custodes: they were taller, stronger, faster and more intelligent. They were also incredibly charismatic -err... except Batman, Angron, Morty, Perty, and Dorn - and were well suited to their role as the generals and leaders of the Imperium of Man.

Problem was, despite all that they were only human, and ultimately their sibling rivalries (and Chaos corruption, in the case of several of them) boiled over and ultimately developed into the Horus Heresy.

History

The Primarchs were created in a secret underground laboratory on what used to be the Himalayas, under the tightest security. All of them were derived from a subset of the Emperor's DNA that served as a template, which was altered differently for each of the Primarchs; it is also thought that he engineered them spiritually as well using long-forgotten psychic techniques. As the Raven Guard discovered after the Emperor granted them access to the original data from the Primarchs' creation, many of the Primarchs' gene-samples were wildly divergent from the original template- some had long gene sequences deleted, while others had non-human DNA spliced into them for reasons only known to the Emperor. (A particularly intriguing discovery was one sample labeled "Subject VI", which had extensive amounts of canine DNA added to it.)

The Emperor's original plan was to have his superhuman creations mature safely in his lab and guide them from 'birth' toward the role he'd foreseen for them. However, Tzeentch had foreseen that they would bring an end to Chaos if left unchecked, and in spite of the safeguards the Emperor had set up, the Ruinous Powers were able to spirit the Primarchs away from the laboratory right before they would emerge from their pods and scatter them across the universe (Conveniently, the canine sample get scattered to a wolf-planet) Just as planned. Somehow, the Emperor knew his sons were still alive but had no clue to where they could be nor any immediate way to search for them. So he took it in stride, shrugged it off as a minor setback (unknowingly, this would come to bite him back in the ass nastily later on) and went ahead with the second part of his plan: his Space Marine project. Using DNA samples from each Primarch before they were abducted, the Emperor created twenty legions of Space Marines, in what would later be called the First Founding. They would form the core of the armies He needed to conquer the galaxy, and the absence of the Primarchs leading those would only serve as a motivation for the warriors to search for them.

One consequence of the abduction, however was that each of the young Primarchs were forced to adapt to the lifestyle on their new homeworld, something which would influence and mold them throughout their lives. The Primarchs rapidly grew to adulthood and quickly rose to power, often becoming the leaders of their world. As the Emperor crusaded to unify the galaxy he would occasionally stumble upon another long-lost son. When this happened, the Emperor would hold a celebration in honor of this discovery, give the Primarch their Legion to command, then tell them to fuck off and start conquering worlds while he fapped to his favoured offspring. The Emperor was a dick like that. (Or rather, he never saw the Primarchs as 'sons', just as carefully crafted tools to enforce his will and vision so he in essence made them get at it on the double to catch up with His schedule. Which is actually even more Dickish.)

The first Primarch the Emperor discovered was Horus, who would become the Emperor's favoured son. The majority of Primarchs somehow recognized the Emperor on sight, immediately pledging their allegiance to their father. A few (such as Leman Russ and Vulkan) only swore allegiance after being bested in a contest. The only exception is Angron, who outright refused to follow the Emperor as he preferred to die in battle along with his rebels brothers and sisters in their fight against the oppressive Not-Romans. The Emperor simply shrugged and abducted his son, leaving Angron's followers to get slaughtered. Angron never really got over that dick move.

At the end of the period known as the Great Crusade, Horus, who had recently been promoted to the title of Warmaster, fell to Chaos and rebelled. It didn't take long for eight other of his fellow Primarchs to join his side against the Emperor, resulting in a full-scale civil war known as the Horus Heresy. Funnily enough, most of the Primarchs who sided with Horus were those who felt that the Emperor had taken a giant, steaming dump on them. So while the Emperor is the greatest tactician, biologist, warlord, and leader in the history of mankind, he's worse than a crack-addled transient junkie as a father.

As mentioned above, the Emperor's attitude toward his Primarchs was also heavily divergent to that of the greater Imperium. Whilst he indulged them in the idea that they were his "sons", privately, he didn't view the Primarchs as his literal children, analogising himself as Gepetto to 20 (21) different Pinocchio's. The Emperor even referred to Angron as "The Twelfth" rather than refer to him by name. Although this seems like typical Emperor douchebaggery, he may have behaved in this way because the Primarchs themselves prompted that dynamic, and it was easier to just go along with it. Leman Russ once boasted to Constantin Valdor that the Custodians would never understand the Emperor like the Primarchs could because they weren't "family", even calling the Custodians the "instruments" to be tossed aside when He cared to; Valdor's response was "there are so many errors there, I do not even know where to start".

Malcador also claimed that the Primarchs were but a means to an end; designed to be "conqueror's tools and nothing more", built to dominate and compete with each other, eventually intended to challenge each other and eventually confront the Emperor himself, he further claimed that the Primarchs had no free will and that the a civil war like the Horus Heresy had always been part of the Emperor's design, although he later admits that he had to lie to spare his servant sorrow on her deathbed, so it is probable that the Primarchs were simply beyond expected control. In a separate instance: Valdor claimed "we turned on one another, driven by pride and human resentment" which assumes some measure of responsibility for the Heresy rather than completely blaming the Primarchs, and after that point he wasn't prepared to challenge Rogal Dorn over decisions regarding the fate of the Custodes, even though he believes he had the capacity to challenge Dorn on the matter, calling the Primarchs "creatures of power, built to dominate"; all hinting that while they may have had an original function, they probably turned out quite differently from expected and the final result might not necessarily have been them turning on each other and fucking up the human webway. Although Valdor did once angrily claim that the entire debacle could have been avoided if the Custodians had just intervened at the Primarch's births.

Despite all this, the Emperor still refers to the Primarchs as his "sons" in private revelations with Malcador, though in the same instance while playing out the strategy of the Horus Heresy using their destinies he is absolutely aware that in order to win the game against Chaos they need to be played against each other: sacrificed or manipulated in order to get the best possible outcome. Malcador does point out that there are different ways to play the game and realizes that destinies can unfold in different ways and that the Emperor is forced to make certain decisions in order to avoid losing outright, so the battle unfolds the same way no matter what strategies are used. Only the final outcome was kept from Malcador until it became clear that the only way to win was for his piece ("the Fool") to switch places with the Emperor in the final move, quite possibly at an absolute cost to his immortal soul and leave the "Uncrowned King" piece to play "Salvation". So seems that the Emperor manipulated everybody, but only did so to achieve the best outcome for humanity based on the plays available to him. Of course, whether or not this was as the Emperor planned, or just him being forced into these decisions by the more subtle actions of Chaos, is up for debate.

Primarchs and Legions

Legion Number	Name	Homeworld	Name of the Legion	Allegiance	Description/Current Status	30k/40k
I	Lion El'Jonson	Caliban	Dark Angels	~~Loyal?~~ LOYAL	Crushes the horrors of Old Night, destroys worlds, whole civilizations, erase stuff from history. Sees himself as a man that no one else can compare to and constantly toils to maintain this standard (although he wasn't as excessively vainglorious as Fulgrim). Unlike Fulgrim however, The Lion's greatness caused him to be a hardcore pragmatist and largely detached from everyone around him. The Lion just couldn't relate to anyone else not even close to his level (even most of his brother primarchs couldn't fit the bill), so he always felt alone in the universe. Was a bit of a loose cannon with a long but explosive fuse. The Lion is as smart and introspective as he is merciless and brutal. He wasn't necessarily easy to piss off like Angron, but anyone who manages to cross his threshold of patience will find themselves on the business end of his weapon. Several times. And possibly dismembered to boot. Fought Luther during his betrayal at the end of the Horus Heresy, where he was wounded from their duel. He survived however, and was spirited away and tended to by the Watchers in the Dark in a super secret chamber in The Rock (that not even the Dark Angels knew about), where he spent the last millennia healing his wounds. As of the current edition; The Lion is now supposedly fully healed and all he's waiting for is the Emperor to tell him to wake up from his millennia-long power nap.
II	+++Records expunged+++
III	Fulgrim	Chemos	Emperor's Children	Traitor	A patron of the arts, who wanted to enjoy the finest and most exotic things in life. Believes that he and his legion should be the avatar of humanity's perfection, and so everything about them should be flawless, everywhere from appearance and actions to their fighting style. Due to this, Fulgrim's battle tactics revolved around utterly perfecting their strategies. Everything from his soldiers to their strategies were intensely drilled until their fighting was closer to a intricately-choreographed play of death than anything. To him, war is an art, and he wanted to perfect his arts. A master blacksmith in his own right, capable of forging weapons that even Ferrus Manus couldn't help but deem "perfect". His artwork however, wasn't always the best in the universe due to being so perfect it hit uncanny valley levels. Was initially corrupted by Chaos through the Laer blade, a Slaaneshi-possesed daemon sword he looted as a trophy, but wasn't aware of what Chaos was. He would fully give in to the temptations of the sword after he beheaded Ferrus Manus, where his utter grief at the act caused him to succumb to the daemon within the sword. Daemon Prince of Slaanesh, ruler of the Pleasure World. ~~Fulgrim's actual consciousness however, may or may not also be still imprisoned within his own body by~~ the daemon who possessed him in the first place was eventually conquered by Fulgrim's inner will or whatever, but his new personality is generic "DEMON PRINCE OF THE DARKNESS AND EVIL". Managed to incapacitate Guilliman at one point by slicing his throat with a poisoned sword. Still has a soft-spot for his brother Ferrus. He asked Fabulous Bile to clone his brother several times so that he could attempt to lure Ferrus into Chaos' side again. All his attempts have ended in failure, which he has blamed Fabius for due to his certainty that a "perfect" clone would join him. Heard about Big G waking up and is a bit buttmad about it at the moment. He tried to give Guilliman a cursed artifact during his return party, but was found out and subsequently banished. Needless to say: he mad.
IV	Perturabo	Olympia	Iron Warriors	Traitor	A man who was already had the knowledge to create the best at everything he did from birth. Perturabo considered this a curse however, feeling it robbed him of any sense of accomplishment while growing up, contributing to his eternal grumpiness. Originally preferred diplomacy and was an admirer of the arts during his time in Olympia, but meeting the Emperor (who had no time for such things) caused a violent switch to flip inside Perturabo's mind, turning him into a ruthless warlord throughout the Great Crusade, likely because he wanted things to be different from Olympia once he joined E-money, but once he realized that The Great Crusade was basically Olympia 2.0; he just gave up, flipped the table, and accepted how things really are and played the part. Just as much as a master of siege warfare as Dorn (both in offense and defense), but the lack of opportunities and recognition led him and his legion to be specialists of tearing shit down. Unlike Dorn however, Perturabo's general strategy is a combination of stubbornness and ice cold-calculating efficiency, orchestrating war like it was one giant math problem. The problem with this is that he didn't even see his sons as people. As far as he was concerned, they're just armored meatbags who pull triggers and push buttons and were about as expendable as guardsmen. Suffers from a massive inferiority complex, partially due to his certainty that the Eye of Terror was always watching and judging him. Nobody believed him when he said this, so it was mostly attributed to Rogal Dorn, whom the Emperor greatly favored over Pert, despite having similar skillsets. Daemon Prince, ruler of Medrengard. Described as the ultimate Obliterator; so expect him to be carrying around titan grade weaponry and millennia of pent-up RAEG when he finely shows up. Given that Magnus, Fulgrim, and Mortarion are back in action; he'll probably come out eventually as well.
V	Jaghatai Khan	Chogoris/ Mundus Planus	White Scars	Loyal	Never wants to stay still, prefers to hunt down xenos enemies. An observer for the most part. While little people wanted to learn about the White Scars and their culture; The Khan studied everyone, gaining tons of knowledge about Imperial cultures and norms. Unknown, disappeared into the Webway while hunting Dark Eldar after they raided Chogoris.
VI	Leman Russ	Fenris	Space Wolves	Loyal	Had a high opinion of himself and his legion, if only because he felt that he's earned that kind of respect through the centuries. Of all the Primarchs, Leman was the one most willing to cross any line to do what the Emperor asked, at least at first. Later on, he decided to become his own man and protect the people of the Imperium. Also notable for curbing the more savage tendencies of the Wolves and teaching them to control their ferocity, unlike some people. Wanted to test his legion all the time, to prove he is the best. Unknown, disappeared into the Eye of Terror with the 13th company but promised to return one day. Magnus supposedly knows where he is, but he isn't telling. The Wolves found ~~his armor in a Khornate Shrine~~ an armor rumoured to be his on the Temple of Horus on Rudra, implying he either; turned into Wulfen, to Chaos, is dead, or is murdering his way through the warp as a half-naked barbarian. Allegedly a figure resembling him was spotted with the 13th company during the 13th crusade.
VII	Rogal Dorn	Inwit	Imperial Fists	MEGA DUPER Loyal	A brutally honest and steadfast man, but was equally indifferent to those around him. Dorn's personality is akin to a wall, he was a man you could take at face value; he would never lie or deceive you, and he would always speak his mind without a hint of falsehood, even if it ends up working against his favor. That said, he could never properly relate with other people's emotions. He will speak the truth, but lacked any glib of tongue to express it in a way that wouldn't feel like he was delivering it with the bluntness and intensity of a power fist to the face. Embodied the "soul" of the Great Crusade unlike any other; he received the most accolades from the Emperor and fought alongside him most often. A master of siegecraft, although fortifications was his forte. So much that he was tasked with fortifying the Imperial Palace. He would also build grand fortresses on the worlds they conquered. Assumed deceased, disappeared while boarding a Chaos cruiser during a Black Crusade. One of his fists were recovered and its skeleton is placed in a shrine, where each new Chapter Master of the Imperial Fists engraves their name upon it. Rumored to still be alive, though that begs the question of whose fist is in the Phalanx.
VIII	Konrad Curze	Nostramo	Night Lords	Traitor	A man of justice who believed that he needed to instill absolute fear into people to ensure lasting peace. Possessed psychic powers that allowed him to perceive the future in short glimpses. The problem was that they were uncontrolled and they constantly subjected him to see the worst possible future in the darkest, most vivid detail possible, including the deaths and fall of his brother Primarchs as well as the Emperor's own entombment on the Golden Throne. This only served to widen his ever-growing insanity. An unstable sociopath, to say the least. Curze's visions, upbringing, and perceived need for brutality took a heavy toll on his sanity, but he held firm under the belief he was making the galaxy a better place, like what he did with Nostramo. This all came crashing down after Nostramo reverted back to its old ways when he was away; deciding that nothing would ever change, he chose to bombard his home planet into rubble. That said, he was a master at infiltration and unconventional warfare, just as much as he was a master of scaring the shit out of people. His crowning achievement is that he managed to fuck up Guilliman's Imperium Secundus by himself, no aid from his legion what-so-ever, something his brothers couldn't even come close into doing. Lost what little sanity he still had after destroying Nostramo. By this time, Konrad stopped justifying his methods to himself and fully embraced the depraved side of his "Night Haunter" persona, spreading untold terror and pain wherever he went. By the time of the late Horus Heresy, the Emperor wanted to put a stop to it and sent a Callidus assassin named "M'shen" after him. Curze knew about her mission from the get-go but he made sure the assassin could reach him unimpeded. He did not resist when she entered his chambers and asked the Callidus to kill him. There are believed to be two reasons why this might have been. One is that Konrad realized he became the very thing he sought to rid the galaxy of and knew what had to be done- a perceived hero who lived long enough to see himself become a villain. The other is that the assassination vindicated everything he'd ever said and done; he punished and killed evil-doers and now the Emperor used his own methods to kill him, thus proving that all his atrocities were both justifiable and necessary. Whatever the case, Konrad was already a jaded, broken man after the Nostramo debacle and wished only to die.
IX	Sanguinius	Baal	Blood Angels	Loyal	A noble but unparalleled warrior, known for the angel-like wings that grew from his back. Was known as the greatest exemplar of the Emperor himself, mirroring many of his father's best traits, instead of only one or two of them like his brothers. If anything, Sanguinius is a reflection of what the Emperor could have been as a truly benevolent being, concerned not just for mankind's future, but man as individuals as well. A pretty cool guy to be around. Despite being a fabulous, angelic demi-god of war; he had mankind's best wishes at heart and fought for it with graceful ferocity, hell even the Primarchs couldn't resist Sanguinius being so bro-tier. He is essentially the vampiric, bishie version of Vulkan. Showed the same amount of concern for his legion. Sanguinius did all that he could to hide the Red Thirst from being exposed to the wider Imperium, knowing full well that the Blood Angels would receive the II/XI Legion treatment if it came to light. Psychic, and capable of seeing glimpses of the future. He was powerful as he was nice, Sanguinius was one of the most powerful of the Primarchs in terms of martial prowess. Feats include; ripping the wings off a bloodthirster and literally throwing him to the warp, single-handedly holding a defensive point during the Siege of Terra against numerous traitors, and managing to damage Horus' armor even after being exhausted from literally soloing entire armies. Deceased, slain by Horus. His body is currently in a stasis crypt in Baal, so his corpse remained fabulous for the last 10,000 years. Commemorated during Sanguinala, a holiday dedicated to his memory.
X	Ferrus Manus	Medusa	Iron Hands	Loyal	Wants to get things done quickly, without needless philosophizing. Contrary to his sons; Ferrus wanted to advocate the strength of one's flesh, rather than relying completely on bionics and mechanical augmentations as shown by the Iron Hands, if any he was appalled at the idea of turning man completely into machine. He wasn't able to realize this after getting a viking crewcut by his best friend, however. A master artisan, thanks to his metal arms, which allowed him to practice his craft with incredible precision and detail. Deceased, slain by Fulgrim and his head offered to Horus as a gift. Fulgrim still has the body, which he repeatedly clones and murders again in a futile attempt to make him turn traitor. Some claim he is still alive on Mars, though it may be not actually be him.
XI	+++Records expunged+++
XII	Angron	Nuceria	World Eaters	Traitor	Embodies the name "World Eater". He and his legion consumes entire worlds in a whirlwind of indiscriminate slaughter until nobody but them is left, pre and post-Great Crusade. No real ambition beyond endless slaughter, thanks to the butcher's nails augment jammed into Angron's brain. It also made him incredibly violent and quick to anger. At first it was to satiate the unending bloodlust generated by the butcher's nails, but now its to glorify Khorne. One of, if not the most, powerful of the Primarchs in terms of sheer combat prowess. Angron could kick anyone's shit, Sanguinius and Horus included. That said, his ability as a general is lacking. He could murder armies sent against him, but he lacked the tactical acumen (or anything resembling sanity) to focus on the objectives truly needed to win a war (although in Angron's head: murdering all of his opponents is the only way to win a war). Daemon Prince of Khorne. Spend most of his time Getting Shit Done and being banished to the Warp for a hundred or so years after Imperum responds to his blood crusades. Was one of the largest reasons for fucking up the Horus Heresy. If Angron kept his murderboner down for just a few more minutes and let Horus finish off the remaining loyalists on Istvaan with another Exterminatus strike; they would have been able to march to Terra faster and with much more manpower and have a better chance at winning. Whether this was Angron just being Angron or a secret ploy by Khorne to keep the blood flowing by thinking past the Horus Heresy is unclear (after all, if Horus won; Chaos eventually starves to death. If Horus lost; he has a aeons' worth of blood and conflict to revel over.).
XIII	Roboute Guilliman	Macragge	Ultramarines	Loyal, barring that one episode he doesn't like to talk about	A proud but fair visionary who always looked towards building a better future for humanity. Guilliman never did anything without thinking what would happen at the end of the day and he always tried to plan a better outcome for whatever he did, whether its building an empire or subjugating an enemy civilization. Was more for the people than the Emperor, hence why he thought preserving his Imperium was more important than the survival of the Emperor himself. A general first and warrior second, which was the key to his success throughout the Great Crusade. He wasn't the best at crossing swords or gunfights, atleast in comparison to his brothers; but he was exceptional at commanding his forces and resources, ensuring all wars he fought in were running at optimum efficiency. The greatest statesman among the Primarchs. Guilliman was best remembered for his ability to set up an efficient form of government on every planet his legion conquered, turning them into model, self-sufficient worlds in order to prepare them for the future after the Great Crusade. This is best exemplified by Ultramar, which still remains one of the most powerful and idyllic planetary systems in the Imperium, even after 10,000 years. He's also a logistical genius, and invented the organizational model that 8 of the 9 First Founding Chapters still use (more or less). Previously kept in a stasis chamber after his throat was sliced by Fulgrim with a poisoned sword. Recently revived with the help of Belisarius Cawl and the Ynnari and their new soul manipulation powers. Is now active once more, and not very happy with how badly the Imperium has gone to shit since he was not-quite-dead. Currently back in his old role of Lord Commander of the Imperium, trying his hardest to keep the Emperor's work from going completely down the drain while while waging an unending war against the forces of Chaos and the Imperium's equally monstrous bureaucracy.
XIV	Mortarion	Barbarus	Death Guard	Traitor	A bitter yet petty man, kind of like the edgy goth kid of the group. Mortarion didn't want to associate anyone who hasn't gone through the same brand of abuse he has during his childhood and also hated those who had relatively comfy ones in comparison (like Guilliman or Dorn). He would only find some friendship with Konrad Curze (due to his "raised alone and became psycho-Batman" origin) and Horus (because just about everyone likes Horus). Has an immense abhorrence for psykers and the warp, due to his experiences in Barbarus. As a daemon prince, he is the very thing he hated in the first place. He takes the resulting bitterness out on everyone else in the form of horrible diseases. Stubborn to the core. Mortarion's favored tactic that he passed onto the Death Guard is a combination of attrition and unrelenting assaults; they take the pain while dishing it out in greater amounts, non-stop. He also valued individualism throughout his legion, largely leaving it up to his troops to figure out the best strategy in a conflict, rather than micro-managing them. Was already disenchanted by the Imperium by the start of the Horus Heresy (Seeing the Emperor and his works as total hypocrisies), so he threw his lot in with Horus. However, due to a ruse by Typhus; he and his legion ended up being infected by a virulent Nurglite plague while in the warp, which caused them to be in a constant state of agony but remain alive due to their Astartes-grade toughness. Unable to bear the pain and see his sons suffer; he pledged his loyalty to Nurgle and the god "cured" them of the plague (cure is probably incorrect, it was more of mutate their bodies to be compatible with the plague). From here, he became a daemon prince. Went back to the warp after the Horus Heresy, where Nurgle gave him dominion over the Plague Planet, which he shaped into the image of Barbarus. Was banished by Grey Knights during the Battle of Kornovin, which was the origin of Draigo carving a name onto his plague-ridden heart (how Draigo did so is a mystery, so we'll just chalk it up to him being too high on drugs to be infected by Mortarion's plagues). Helped Abby by creating the zombie plague, along with other contagions, after he got the Hand of Darkness artifact. He eventually got better and waged a full-scale invasion of Ultramar when he heard that Guilliman's finally awake. Had to retreat after he had to deal with the other Chaos Gods' typical shenanigans (mainly encroaching on his strongholds in the Scourge Stars while he was off campaigning).
XV	Magnus the Red	Prospero	Thousand Sons	Traitor, though he never planned this	An optimistic scholar who thirsted for knowledge and always believed that information should be preserved for the greater good of mankind, regardless of its origins or the danger it might pose. As a psyker from birth, he was sympathetic to the discrimination faced by his fellow psykers and labored for his kind to be accepted. He did so by training psykers to control and enhance their powers, in the hopes of showing to people the benefits of his kind's gifts. This had mixed results with his brother primarchs, especially in the face of the Emperor's "psykers are bad" standing orders. Defying the Nikea council's rulings, Magnus continued to experiment with warp powers and during a Tzeentch-induced prophesy that involved Horus' betrayal; he attempted to warn his father with a psychic message. During the sending process; he accidentally destroyed the Emperor's webway project, causing him to be arrested by Russ and the Wolves to answer for his disobedience. As Horus was already corrupted by this point, he altered the orders to instead destroy the Thousand Sons' homeworld. Realizing he's been played like a damn fiddle by Tzeentch, Magnus' resolve was broken and initially accepted his destiny of being destroyed by the wolves in an attempt to spite Tzeentch, but eventually decided to attempt to rebel against his fate but ultimately failing after Leman Russ beat him up badly. He then made a desperate deal with Tzeentch to save his legion in return for his servitude. He and the Thousand Sons were teleported to the Planet of Sorcerers, where more hijinks ensued with his first captain's certain ritual. Now a daemon prince, one of his first major campaigns was to invade the Space Wolves' homeworld. Was banished, but the Wolves were all but ruined; most of their upper command structure and progress with stabilizing their flawed gene seed was gone. Feeling they weren't down for the count yet; he went in again and bloodied the entire star system of Fenris itself, irreparably damaging the Wolves' home system. Appeared during the Gathering Storm, where he trapped and captured Guilliman and his retinue in the warp. After he escaped, Magnus chased and confronted Guilliman all the way to Luna, but was banished by the Custodes and Sisters of Silence. Now currently biding his time for another offensive.
XVI	Horus Lupercal	Cthonia	Luna Wolves/ Sons of Horus/ Black Legion	DOUBLE TRAITOR	A charismatic strategist who overwhelms his enemies through sheer numbers and precision tactics. Big E's most favored son, always being held in the highest regard, second only to the Custodes. This was a combination of him being the first Primarch found and his long rap sheet of victories throughout the Crusade. Due to his position and experience, he was the most well-liked of the Primarchs during the Great Crusade. Just about everyone looked at Horus as the greatest among them. For all his charisma and leadership, Horus was still wracked with self-doubt once appointed Warmaster, constantly afraid that he was unable to live up to the title. Being overall commander of the Emperor's forces AND being his personal favorite was a lot to live up to. This was one of the reasons why he succumbed to the temptations of Chaos. Was one of the few Primarchs who was suspicious of the Emperor's plans for the Astartes post-Crusade, fearing they'd be disposed of like the Thunder Warriors and was mistrustful of the Emperor's intentions in the long run in general. The Ruinous Powers would also use this to their advantage. Rebelled against the Emperor after being fed a vision of the future by the Chaos Gods, in which the Emperor was being worshiped as a god and many of his fellow Primarchs (including himself) were reviled or outright forgotten. Little did he know that this was to become a self-fulfilling prophesy. His essence has been erased from existence. When the Emperor mustered up the resolve to finally end Horus, he shot him with a psychic blast powerful enough to obliterate his very soul, ensuring that the Chaos Gods couldn't just bring him back from the dead. His body was recovered and brought to the Eye of Terror, but was later destroyed after an incident involving Fabius Bile and a clone of Horus.
XVII	Lorgar Aurelian	Colchis	Word Bearers	Traitor Prime	A charismatic diplomat with a golden tongue, who relied heavily on his unparalleled speaking abilities to bring worlds into compliance during the Great Crusade. Lorgar would always prefer to talk out a peaceful solution, rather than resorting to violence. That said, Lorgar did know how to slap a bitch when needed. A deeply spiritual man, due to growing up in a theocratic society during his time on Colchis. Due to this, Lorgar saw The Emperor as a literal god and decided to spread the good word of the God-Emperor throughout the Crusade. During this time, he penned the "Lectitio Divinitatus", a book detailing how awesome the God-Emperor was, and always built grand cathedrals in all the planets he conquered. As you can imagine, this didn't sit well with the Man-Emperor's secular Empire ,so he decided to bloody one of Lorgar's grandest cities to send a message with Guilliman. Little did the Emperor know what this act of dickery would lead eventually to. With Lorgar being completely disheartened and defeated; Kor Phaeron and Erebus lured him to the worship of the Dark Gods, who were more than happy to accept his rabid fanboyism. He would eventually corrupt Horus and ignite the single biggest clusterfuck in Imperial History, ruining everything that the Emperor has striven to build since the Age of Strife. Rules as a daemon prince of Chaos Undivided and currently located in Sicarius, the Word Bearers' home planet. Unlike his brothers through, Lorgar doesn't really "lead" his legion anymore, instead leaving that to his council of Dark Apostles. As of the moment all he's done for the past few millennia is meditate in the warp and do fuckall. With Big G finally awake and taking the fight to Chaos; its rumored that Lorgar might finally get out of his overdue NEET phase and command his sons again.
XVIII	Vulkan	Nocturne	Salamanders	Loyal	A true man of the people, concerned with the preservation and welfare of humans. Vulkan saw all humans in the Imperium as equals and would protect any servant of the Emperor with great ferocity regardless of their class or status. Growing up in a blacksmith society allowed him and his legion to craft some of the finest wargear the Imperium has ever seen. Its also the reason for their fire fetish in combat. Inherited the Emperor's perpetual powers, granting him the ability to reincarnate after dying. He and his legion took some of the worst losses during Istvaan, and he himself was eventually captured by Konrad Curze. Curze wanted to get his torture fetish on, so he tortured Vulkan to death. Several times. Vulkan's status as a perpetual ensured he always came back, but less and less sane as Curze's treatment got worse and worse. He eventually managed to escape, but accidentally teleported over Macragge's atmosphere, crashing down on the planet like a green comet of insanity. By this point, anything remotely resembling sanity had left Vulkan's mind. He was eventually "killed" by another perpetual, in a well-meaning attempt to reset Vulkan's brain. It worked (sort of. At least he wasn't a howling maniac anymore) and after taking a short death nap, he got better and disappeared for a while. Resurfaced during The War of The Beast and was recruited to lead the Imperial forces against The Beast's forces. Then disappeared after ramming The Beast into a plasma reactor and killing them both in a squall of gore. The Salamanders claim he continued to lead them for a few more centuries after that death, then left them with the Tome of Fire, claiming he had a special mission that they could not accompany him for.
XIX	Corvus Corax	Deliverance	Raven Guard	Loyal	Sought to overthrow oppression, bringing justice to tyrants. Possessed some kind of perception-manipulating psychic power, giving him the ability to be "invisible" to organics (He's still there clear as day, but your mind just can't process that he's right there). Preferred covert warfare, sabotaging, fast strikes and assassinating the enemy from the sides, and only striking in the open when the time is right. Basically one of the few primarchs who uses tactics of actual special forces units. He and his legion were bloodied during Istvaan and forced out of the conflict. Corvus wanted desperately to help the Imperium's deteriorating situation, so he asked the Emperor for assistance. Emps obliged and gave him the template to create the Primarchs themselves, giving him the ability to train marines at an even faster rate. This was wrecked after the Alpha Legion tampered with the creation process, resulting with the majority of the aspirants coming out as horrible mutants and aberrations. While it weighed heavily on his conscience, Corax had to be pragmatic. He made do and used his newly obtained mutant horde as shock troops and it worked; they were able to disrupt the traitors long enough to buy Terra some time to put up a defense. After the Heresy ended, he was reluctantly forced to euthanize his creations, wracking Corvus with a huge amount of guilt. Went missing after heading for the Eye of Terror to atone for his sins, saying only "Nevermore" before leaving. His status is currently unknown, but the Raven Guard believe he's still alive and will return once again. In reality, he is indeed alive and hunting his fallen brothers, although the Warp has changed him into a living, shapeshifting shadow.
XX	Alpharius Omegon	They're not telling	Alpha Legion	Alpharius: sort-of loyal. Omegon: even Tzeentch can't keep track.	Shrouded in mystery. It's not even known what their homeworld is, let alone what their upbringing was like. Forge World gave no fewer than four mutually irreconcilable origin stories, all of which were dismissed as lies. That said, the only discernible fact we can give about them is that the two primarchs did not always agree with each other, exemplified with Omegon actively sabotaging Alpharius' operations during the Horus Heresy. As primarchs of the Alpha legion; the two frequently exchanged roles whenever needed with nobody ever noticing, but officially; Alpharius is the primarch of the legion while Omegon is commander of their elite covert forces. Masters of psychological warfare and manipulation. They didn't need regiments of soldiers or weapons to do his heavy lifting; all he needs is a handful of spies to plant paranoia, deceit, misinformation, and dissent in his targeted worlds. By the time his agents are done: the enemy would either be tearing each other apart and/or distrustful of each other; making them isolated, easy pickings for the main Alpha Legion forces once they're called to reign the planet in. Alpharius bought the Cabal's story about letting Horus kill all of humanity to kill off the Chaos Gods in the long run, and was eventually beheaded by Rogal Dorn during a battle on Pluto. Maybe. Quite frankly, with these two one can never be entirely sure what the truth really is. Omegon took on his mantle officially ("the jest made real") and this new "Alpharius" may or may not have been killed by Guilliman (the Ultramarines suspect they may have only killed a body double). His loyalties are unknown, but he was against the Cabal's proposal, indicating he either thought sacrificing his entire species was too big of a price (which would mean he's still loyal to humanity), or he wanted Chaos to survive by feeding off humanity (which would mean he was a traitor).

Their Eventual Fates

Traitors

General downside to those who became Daemon Princes is that the further they go from the Eye of Terror, the more their power wanes. Also most of them spend most of their time in the Great Game (eternal war in the Warp), growing increasingly distant from the real world affairs.
Horus was killed by the Emperor during the Siege of Terra, who utterly destroyed his soul. His legion enshrined his corpse until the Emperor's Children stole it. Fabius Bile managed to successfully clone him, but Abaddon killed the clone to cement his position as his successor as Warmaster of Chaos. Horus is very dead, but that was his fault for being a fuckwit. (And perhaps it's what he wanted...)
Angron is a Daemon Prince of Khorne. Still gets shit done, but did get his arse handed to him by the Grey Knights on Armageddon.
Mortarion is a fucktwit who rarely does anything of interest (still sulking over his eternal existence as the thing he hates the most), but is a Daemon Prince of Nurgle. Apparently now holds the largest domain in the Eye of Terror, rather than just one planet he had in the old fluff, and also the last Daemon Primarch to bow to the Despoiler during the Legion war. Got some open heart surgery, courtesy of Draigo/Ward. Created zombie plague from one of the artifacts Abbaddon used in his XII crusade. He invaded Ultramar after hearing news that Guilliman's finally awake, though he ultimately had to go back to the Scourge Stars due to his poor fortunes in the war as well as being summoned back by his patron God.
Fulgrim's soul was trapped in a painting while his body was possessed by a daemon for a brief time before swapping places with the daemon and taking its powers (or so he claims). The first Primarch to become a Daemon Prince, although he aimed at achieving (demi)godhood instead (by sacrificing Perturabo). Abandoned what remained of his legion to rule his pleasure daemon world, and didn't tell them how to get there (yet Abaddon somehow manages to contact him anyways).
Lorgar is a lazy fucknut who does nothing since they fled to the Eye of Terror, and handed the rule over his legion to the council of Dark Apostles, but still a Daemon Prince of Chaos Undivided. Taught Abaddon how to summon daemons.
Magnus the Red got broken into several pieces during his fight with Leman Russ, with several of them actually believing they were the real Magnus and going their own way. Some pieces were eventually put back together to form "the Crimson King", the Daemon Primarch form of Magnus who joined Horus in his rebellion. This sometimes also gets shit done, leading armies to the Space Wolves' planet and screwing with the Imperium, keeping his big red trollface on all the time until he gets his ass tossed back into the Warp. Other fragments seem to be floating around throughout history, appearing to have their own agenda, pretending to be daemons or helping the Imperium from time to time. By the time of the Gathering Storm and the 42nd Millennium the disparate fragments have mostly recombined to the Crimson King (leaving out a few key elements, namely the ones who embodied his best qualities; for example, the part of Magnus that embodied his love for his Legion chose to fade into nonexistence instead of being reabsorbed into the Crimson King) making him as whole as he can be.
Perturabo becomes irrelevant after he goes on to drop largely out of post-Heresy fluff, but is still a Daemon Prince of Chaos Undivided. Rules the most stable planet in the Eye of Terror, where he does nothing but watching his sons sieging each other. Helps Failbaddon in a couple of Black Crusades by giving him some Daemon Engines. It doesn't really help, but it's more than Lorgar's done for Chaos Undivided. He is also leading his Legion after the 13th Black Crusade in their new offensive against the Imperium
Konrad Curze allowed a Callidus assassin to infiltrate his lair and kill him, either because he himself became the thing he hated the most, or to justify to himself that every atrocity he has done in the name of justice was a necessary act.
The Alpha Legion's story is a bit complex:
- Alpharius was slain by Rogal Dorn in combat during the Battle of Pluto. He is very much dead as he did not bargain with the Dark Gods and had his head split open by a chainsword. Conspiracy theorists will speculate that it wasn't really Alpharius, though the death is strongly corroborated by Omegon's response. So unless Alpharius used a body double to trick Rogal Dorn AND his own twin into thinking he was dead and allowed Omegon to take his place and identity permanently; there isn't any hard evidence to suggest that the dead "Alpharius" was anything other than the actual Primarch, but knowing the Alpha Legion that doesn't mean too much without definitive proof.
- Omegon reluctantly took Alpharius' identity after he sensed he was dead, and his legion a bee-line for Ultramar after the Horus Heresy, where he met his end after dueling Big Bobby G. However, because the rest of the Alpha Legionaries did not break even after the death of their primarch (in fact they managed to beat the Ultramarines in the conflict altogether); nobody could truly confirm if they did indeed kill the real deal, or if it was a body double.
- While it's been established that a decent amount of Alpha Legionnaires were surgically altered to resemble their Primarch and even believe they were Primarchs themselves; that and the figurehead role of "Alpharius" has been largely interchangable between both the twins and their sons, which makes sense for a legion whose MO is flexible leadership. While we can be reasonably certain that at least one of the twins is dead, whatever "Omegon-Alpharius" or at least whichever person who thinks he's Alpharius have been up to following the Heresy is a matter of fierce debate and speculation.

Loyalists

Ferrus Manus was killed by Fulgrim during the Drop Site Massacre. His body was not recovered, so some Iron Hands think he might still be alive, and for a time it seemed like he did survive. However, Vulkan later exposed the "Ferrus Manus" leading the remaining Iron Hands as a marionette-like machine with one of the Primarch's hands attached to it, destroying the fake soon afterwards. The fact that Ferrus was decapitated by Fulgrim after being defeated and had his head delivered to Horus makes this claim fairly dubious. Just don't say that to the Iron Hands, though. Unless you want free open-heart surgery from a ceramite and steel power fist. Fulgrim did try to clone him (several times) in the hope one of them would join the traitors, but every clone so far has refused and been subsequently killed by him.An apparition of an iron handed giant - the 10th son - was seen leading the charge in an army of human souls against an army of daemons when the Emperor entered the Webway).
Sanguinius was killed by Horus. His body was recovered, and he's the only Primarch who doesn't have any legends about returning, though there are some theories on the identity of the Sanguinor which were later proven incorrect. Sanguinius foresaw his death and accepted it as a necessary sacrifice for the future of the Imperium, in no small part because his visions also warned him that he would only survive the Horus Heresy by becoming corrupted himself. The trauma of his death by the Talon of Horus left a psychic manifestation of him still on the Vengeful Spirit. As of late it turns out his soul has been wandering the warp ever since, only deciding to make himself known to revive Commander Dante when he ended up as Swarmlord-shishkabob.
Lion El'Jonson returned to Caliban only to discover ~~that his friend Luther had stabbed him in the back.~~ THAT LUTHER HAD A PLANET-WIDE PARTY AND EVENTUALLY PASSED OUT INTO A COMA AFTER DRINKING 200 TANKARDS OF SPACE WOLF-GRADE ALCOHOL. He sleeps deep within the Rock, originally on life support and now fully-healed (but none of the Dark Angels seem to know this). Perhaps this is a sign of a coming advancement of the storyline, DUN DUN DUN!
Jaghatai Khan disappeared into the Webway after chasing a group of Dark Eldar. The White Scars think he will return someday, and when you consider the fact that time is just as weird there as it is in the rest of the Warp, there is a small possibility he's still around.
Leman Russ disappeared into the Eye of Terror but promised the Space Wolves that he would return for the Final Battle. Magnus appears to know where he is now, but he sure as hell isn't telling the Space Wolves. Reports during the Thirteenth Black Crusade claim that a figure matching Russ's description was seen leading the 13th Great Company have surfaced, but were never verified. Numerous crusades by the Space Wolves to find Russ have resulted in failure, although they did find ~~his armor in a shrine of Khorne in the Eye~~ an armor believed to be his in the Temple of Horus on Rudra - so either he succumbed to Chaos, was killed by a Khorne champion, devolved into wulfen, or is currently pillaging The Warp as a muscle-bound, half-naked barbarian hero.
Rogal Dorn disappeared during a Black Crusade in a desperate ship boarding action. Only his severed hand was recovered and its skeleton enshrined. Debate rages about whether the Zerg rush of World Eaters killed him, or whether he's still out there, murdering his way through traitors with an Astartes-pattern shotgun and a chainsword grafted where his hand used to be. Original 40K novels stated his entire skeleton was on display on Terra, but it's been retconned to only his hands. Still, a Primarch without a skeleton would be bad-ass, if not a little amusing.
Roboute Guilliman was formerly preserved in a stasis field, seconds from death after he was poisoned by Fulgrim. Fast-forward a few thousand years and some Eldar flubdubbery, however, and Big Bobby G is back in action, and he's mad at the current state of the Imperium. After a private meeting with the Emperor, he assumed direct command of the Imperium itself as Lord Commander of the Imperium. When he isn't curb-stomping traitors to death or otherwise trying to keep the Imperium afloat, Guilliman is busy re-vamping the Imperium with numerous reforms in an attempt to realize his father's dream for humanity. Needless to say; a lot of people are unhappy about this, but they can't exactly tell off one of the Emperor's actual sons and expect not to be on the business end of a Custodes guardian spear. He's also taken the time to rewrite the Codex Astartes as well.
Vulkan got the shit kicked out of him during the Drop Site Massacre, whereupon his fluff gets a bit hazy:
- The old Codex: Space Marines states that his body was never found, only a book containing only the names of nine powerful relics and a bunch of annoying riddles as to where they might be found, penned by Vulkan himself. In the 41st millennium, the Salamanders believe that he is still alive and that collecting the nine relics - they've found five so far - will reveal his location.
- In the Black Library novels, starting with Vulkan Lives the big V had to be dragged into a Thunderhawk in bloody tatters. Kurze captured him and tortured him to death... repeatedly; as a Perpetual, Vulkan would not stay dead. After an indeterminate amount of time and deaths, Vulkan managed to escape by teleporting himself into orbit around Macragge and reentering its atmosphere. When he recovered and learned that Kurze was planetside, he flipped out and went after him. A well-meaning Perpetual stabbed him with a fulgurite (a spearhead-shaped piece of stone that contains a bit of the Emperor's power), hoping to either cure his madness or kill him for good. Now apparently dead, Vulkan was put in a stasis capsule inscribed with the words "Unbound Flame," with an honor guard of Salamanders until his remains could be returned to Nocturne. As of the end of Deathfire, he somehow managed to return to life again, although there's no indication as to whether or not he's still a Perpetual. As of the War of the Beast, he's still alive in M.32, after the wounding of Guilliman. He's apparently been wandering the Imperium for a millennium fulfilling his own oaths, but returns to Terra to take command and reclaim Ullanor from the united Ork race. Even with one of the greatest forces assembled since the Horus Heresy, with the remnants of the VII Legion Chapters, the fight devolved to Vulkan facing off with The Beast one-on-one, and sacrificing himself in The Beasts temple-gargant's core detonating it with both himself and The Beast inside it. Whether both of them died is highly unlikely. He hints that Dorn is also alive, meaning he is either privy to some secret information, doesn't know of his brother's death, or is going insane.
- The 8th Edition Codex reconcile these stories somewhat, by claiming that sources within the Salamanders themselves believe Vulkan led them for three millennia (which accounts for his appearance during the War of the Beast), sometimes falling in battle but apparently always returning (also accounting for his perpetual status). He eventually disappeared on some final undocumented mission, not without leaving his Tome of Fire and bequeathing his personal artefacts to the chapter but not actually saying where they were, giving rise to the legend that if they are all found he will then return.
Corax disappeared into the Eye of Terror as an atonement for putting down the mutant hordes he created in trying to create Space Marines out of desperation. Quoth the Raven: "Nevermore." Beyond the Imperium's eyes, his wraith-slip powers began to mutate and he became a shadowy shapeshifter hellbent on killing all his traitor brothers.

Two Missing Primarchs

Who are the two missing Primarchs, you ask? Sigmar and Archaon (depending on how WHFB fits in with 40K, if it does). Or maybe (per /tg/ canon) Rachnus Rageous and Tialoc Ekans. Samus and Guts are also contenders, and many Bolter and Chainsword regulars consider Icarion and his Lightning Bearers to be their headcanon II Legion. It is also highly possible that the XI Legion Primarch has now become Malal and the Sons of Malice Chaos Space Marine warband are the remnants of the 11th Legion (Possible, because Malal's sacred number is 11 and the two unknown legions are the II and the XI) ...

Okay, fine. Nobody really knows. What has been established is that they got killed for some reason and the existence of their Legions was wiped from record by the Emperor. Malcador the Sigillite claims that the Primarchs had been manipulated from the start, and were to be maneuvered into their proper roles prior to the Horus Heresy and those which would not be manipulated would be removed. Although Malcador's own testimony is tainted by the fact that he later admits he had to lie, though many of his statements do mirror what we have seen from the Emperor's own statements.

Games Workshop have mentioned Primarchs besides the eighteen above on other occasions, but they backtracked since. Back in the first edition of Warhammer 40,000, all twenty First Founding Chapters were known, as were their Primarchs (though, at the time, the Primarch was just the first Chapter Master). Of these, the Valedictors and Rainbow Warriors were declared in a later White Dwarf to have been founded after the Second Founding.

Later, in the short story Hell in a Bottle from the novel Into the Maelstrom, a chapter known as the Iron Hearts get fucked over by a Chaos Lord. The short story also mentions that the Chapter has a Primarch known as Rubinek. Of course, this was just a huge cock-up on the author's part, who himself admitted that he meant Chapter Master.

The Horus Heresy novels fill in some of the blanks, but they still leave a lot of questions open. In The Lightning Tower Rogal Dorn says that the lost Primarchs' disappearances were "separate tragedies", so it seems like they disappeared in two different incidents. Deliverance Lost suggests that whatever happened to the missing Primarchs occurred sometime before the Emperor found Corvus Corax, as Corax asked the Emperor why there were only sixteen other Primarchs waiting for him if he was the nineteenth (it's unsure whether this was referring to him being the Primarch of the nineteenth Legion, or him being the nineteenth found); the Emperor avoided the question, claiming that "it would be a discussion for another day". This is no longer the case, somehow, as he is now the third-to-last primarch found, right before the second missing primarch. The First Heretic specifies that the missing Legions were purged at least 43 years before the Drop Site Massacre, so we can conclude that neither one took part in the Horus Heresy. At the same time, members of the Word Bearers Seventh Company travelling through time with Ingethel the Ascended reveal rumors that the surviving members of the lost Legions were folded into the Ultramarines (their Chaplain thinks the rumor is a load of grox-shit, but their Captain does note that the Ultramarines are on record as receiving an increase in troops). Finally, it also adds that the remaining Primarchs had to swear an oath never to speak of their missing brothers and that the missing Primarchs' corresponding legions were personally purged by the Emperor, so it had to have been something extraordinarily bad. Leman Russ mentions in Prospero Burns that the Space Wolves had fought other Space Marines before the attack on Prospero, which may have something to do with the purge. A senior Space Wolf describes Russ' "wyrd" as being "the Emperor's executioner". Several books since have backed this up. In The Dark King, when asked if he will report the Night Lords for censure, Dorn remarks that he feared to add another empty statue to the Emperor's palace, implying that the missing legions were exterminated for committing severe atrocities. Gene-seed flaws might have played a major part- in Fear To Tread, Sanguinius admits to Horus that he had not told the Emperor about the Red Thirst because he feared that the Emperor would purge the Blood Angels in the same way as the missing Legions. In Scars there's a reference to rumours and "whispers of past atrocities" that only a Primarch could kill another Primarch. Russ also turns up and talks a bit about fighting Magnus, and the resulting "shame". So if he's responsible for offing one or two of his brothers, they must've done something pretty fucking heinous. Fulgrim: The Palatine Phoenix mentions that the 2nd Legion's "normally contemplative" Primarch had accused Fulgrim of arrogance prior to the first solo mission that the Emperor's Children went on, which means that at least one missing Primarch was found early enough to have some kind of interaction with his brothers and make a contribution to the Great Crusade. The Regimental Standard article "Field Dressing a Lasgun Wound" makes reference to the II and XI legions taking part in the Rangdan Xenocides but cuts off before their names are given.

Out of universe, Rick Priestley admitted that the unknown legions were supposed to be a reference to the three Roman legions wiped out in the Battle of the Teutoburg Forest, whose numbers were never reused after they were slain to a man by Germanic barbarians. The intention was to let fans design their own Legions to fill in the gaps for themselves, though the implications that this would have on the setting clearly weren't thought through. Nowadays, it doesn't even really let people do much with homebrew fluff since the setting has developed in such a way that it's almost impossible for someone to connect a homebrew chapter to the missing primarchs without getting laughed out of their Local Game Store.

Rules on the Tabletop

Thanks to Forge World, not only do we have models for the Primarchs, but rules as well. As you can guess, they are ungodly death machines who can easily win their points back and more. That's not to say they're invincible, though; they can still be killed if you screw up badly enough. All currently released Primarchs have the following statlines:

As of 8th edition (special rules not included):

Each of them have one or two close-combat weapons, all of which are AP2 or 1, backed by some decent gun to lay some dakka down while they run to the glorious melee. Their Primarch rule acts like a big bundle of USRs wrapped up together in one package, and as ICs they can join squads as well (though most of the Primarchs are better run solo). Each of them have a page worth of special rules and unique wargear, both of which can be stupidly powerful to the point of broken, but that's OK since even the cheapest of the Primarchs costs more than 350 points and eats an extremely valuable Lord of War slot that might otherwise be spent on a Thunderhawk or a Fellblade.

Pimpin Rides

Also worth mentioning, that Perturabo and Rogal Dorn are special enough to get their own personal special/unique vehicle, other primarchs may get their own vehicles in the future (who knows?). However, rules dictate that neither vehicle can be taken in games under 3000 points. Meaning you can only use it in 3000+ matches.

Perturabo gets to ride in The Tormentor, a Shadowsword with the Command Tank upgrade. Not only that, but Perturabo is so awesome, he managed to somehow give it 15 troop capacity, meaning it can take 12 Power Armoured dudes + himself, or 6 Terminators for his bodyguard. But, it doesn't stop there! It also has a single Void Shield! It costs 25pts more than a normal Shadowsword with the same upgrades, but following FAQs it also has BS4, free sponsons, and gains Tank Hunters/Monster Hunters any time it fires all its guns at one target.
Dorn, on the other hand, gets a customised Thunderhawk Gunship, the Ætos Dios. This ship has Turbo Laser as standard, plus a single Void Shield to protect it, it also has It Will Not Die so can regenerate some of its hull points and finally it ALSO has a 4+ invulnerable save against missiles, all on top of being a flyer which means you can only snap-shot at it, all for the bargain cost of 600 points - which is actually 175 points CHEAPER than a normal Legion Thunderhawk with a Turbo-Laser.

Douchebagginess

It is well known that most of the primarchs were douchebags to varying degrees.

From least to most douchebag. Note, the scale really drops off into fucking douchebag after Jaghatai, and straight-up villain after Fulgrim. Also, depending on what they did, the Lost Primarchs may be even worse than all actions depicted here.

Vulkan - The least douchebaggy primarch by far. Vulkan routinely put the life of him and his men on the line for the sake of the Imperial citizens. Vulkan would throw himself to the defence of a no name human tribe with the same ferocity and zeal as he would Terra itself. A total bro. Also was the largest, strongest Primarch (Ferrus' metal arms were determined as cheating) and held back in sparring for fear of hurting his brothers. His only real fault was that, despite his strong distaste for terror weapons, he had a thing for setting people on fire. The only times he was an asshole were when he forgot who he was. Of course, he's still a Primarch and a fierce general, and he will beat the shit out of you if you end up on his shitlist.
Sanguinius - Despite some... unorthodox tendencies, he is reported as being the most charismatic of the primarchs, perhaps second only to Horus. He taught his men humility and nobility, and put the well-being of humanity above any personal glory. A pretty all-round nice guy (except for that little aforehinted bloodlust problem). And he can also lapse a bit as seen in his treatment of Curze by denying him a chance of changing his fate & earning forgiveness. On the other hand, Curze did have it coming for how he massacred Sanguinius' bodyguards. Like Vulkan though, he can still be a ferocious force if riled up, he once beat the shit out of guy for daring to imply the Signus III campaign was a trap (it was a trap but Sanguinius wasn't aware of the Isstvan conflicts at the time, and therefore still had no reason to mistrust Horus.)
Magnus the Red - For his faults, Magnus was one of the nicest Primarchs right up there with Vulkan and Sanguinius. Before the whole Prospero thing, this guy's MO was all about the advancement of humanity: always trying the diplomatic approach to preserve what could be preserved, using shock and awe tactics to limit damage when fighting, happily taking remembrancers along his legion (Although all remembrancers amongst the fellowship were psykers to some degree). Magnus was a friendly and open-minded idealist, which makes it all the more tragic when he gets deceived, framed, backstabbed and then coaxed into selling his soul to the Cuttlefish of Keikaku. He is easily the most sympathetic of the traitors, considering he only joined them after being backed into a corner; had Jaghatai been at his side during and after Nikaea things might have turned out differently. He was also the only traitor primarch who actually cared about his men, even after ascending to daemonhood. The novel Deathfire also ups his bro-ness quite a bit, as he proved himself the only traitor-aligned Primarch to sincerely do something very helpful for one of his loyalist brothers after the Horus Heresy was already in full swing. This "special favour" is made all the more striking given how it took place after Magnus had his adoptive homeworld burned out from under him. Perhaps his skin was red not only because of mutation, but because it also showed the greatness of his heart?. On the other hand, this was done by one of the fragments of Magnus that embodied his better qualities (which would either be reabsorbed into the Crimson King or cease to exist), so any hope that he has good heart died after Ahriman's failure at his Second Rubric on Prospero.
Corax - Even after being raised under the tyranny of the Kiavahrans, he refused to take after their tyrannous ways, wanted to make things right, and asked the Emperor to end the civil war he started while liberating his homeworld of Lycaeus. Seeing the ruthless tendencies the Terran members of his legion had, he quietly shipped them way the fuck away from the rest of the Great Crusade to go fight xenos or had them all slaughtered during the Battle of Gate 42. One of the only primarchs to readily admit his own mistakes, which were many and sometimes tragic.
Jaghatai Khan - Despite him being modeled after the guy who holds the high score on raping and pillaging, Jaghatai was actually very reasonable and a pretty fun guy to be around. His main hobbies included raiding and jetbikes, but he had an appreciation for the fine arts as well. He was very good friends with Magnus and very pro-psyker. However he also kept his distance from pretty much everyone else, save Horus, not wanting to deal with other people's bullshit, unless they were really worth the effort - as the result very few people knew and trusted him (especially once his only bros turned traitor). While the Khan didn't seem to care too much about the whole Great Crusade thing and spent most of his time doing his own thing, he never turned his back on the Imperium, despite being one of the two Primarchs to fully recognize how flawed the Emperor was; he declared that Big E was "neither a monster nor a simpleton", mostly because he knew that Chaos was even worse.
Guilliman - R.G. is a jerk with a (or rather two) heart(s) of gold or a nice guy with a nasty mean streak, depending on how you look at him. Some people might say this dude was a statesman in the same vein as Augustus Caesar- he was great at building states and making life generally better for people, but only if you ignore the deported and murdered people who didn't agree 100% with the new regime. For somebody more reasonable, Guilliman was perhaps one of the most responsible and human among his brothers. He cared about the common man, personally planned post-war reconstruction and political integration into the Imperium of the planets he conquered and (unofficially) tolerated moderate presence of religion in Ultramar. But for sure the guy had a big ego, as he constantly spoke and behaved like he knew what was best for everyone, at least until proven wrong (multiple times). And you better not get on his shit list, although to be fair he was mostly a complete jerk with people he considers being psycho mass murderers with no respect for their own sons or civilian populations. And despite what some people would have you believe, he knew he couldn't plan for every situation and expected people to use their own judgment rather than blindly follow his codex. Like Jaghatai Khan, we know Guilliman recognized that the Emperor was a horrible father and that the ideals the Emperor espoused were far more important than the Emperor himself ever was. While he's grown more cynical since his revival and subsequent realization of how badly the Imperium has devolved in his absence, he has refused to abandon his noble ideals or his faith in humanity as a whole.
Horus - Pre-Heresy he was a surprisingly chill dude, except if you crossed his sensibilities. Got along well with the regular people and his brothers, but he gradually started treating some of them like shit after becoming Warmaster. His insecurities may have also made him vulnerable to the Dark Gods' lies when he received a vision of the Imperium 10,000 years into the future where the Emperor was worshiped as a god, he and many of his brothers were forgotten, and everything was Grimdark--a future that, unbeknownst to him, he would be directly responsible for creating specifically as a result of his own attempts to avert it. The whole heresy thing just sort-of kills his position on the list. After going full Chaos, he rapidly became a much, much bigger dick.
Rogal Dorn - Although one hell of a masochist, and at times thick-headed, he did see the idea behind the Imperium, and actually agreed with it. Honest and dependable, while Rogal didn't make for interesting conversation, he would always do his job without complaint. Had as much empathy and subtlety as one of his fortresses and ended up hurting a lot of people (mostly emotionally, but sometimes physically too) with his over-the-top brutal honesty. The prime example was when he betrayed Fulgrim's trust after they had a discussion regarding Konrad's visions, and provoked Curze into slashing him across the face. However, he could occasionally get quite philosophical, and is perhaps the only Primarch to admit that his own nature and power unsettled him.
Leman Russ - Nowhere near as much of a dick as butthurt Magnus fanboys would have you believe. He was indeed savage, brutal, and myopic (being as violent as Angron and using psykers like Magnus while shunning both for those traits); but ultimately always keeping the larger goal of betterment of humanity in sight and having good reasons for that myopia. Prone to picking fights with his brothers and destroyed Prospero under questionable circumstances. That said, he used the culture of his homeworld to give his Legion control over its savagery, and made the Space Wolves focus on protecting people from monsters instead of just butchering civilians. He did use terror tactics, mass killings, and the destruction of knowledge, but he did so out of loyalty to humanity and the Emperor, not just because he felt like it. Bottom line: Russ certainly had his fair share of flaws, but as belligerent and myopic as he could be he always tried to make the galaxy safe for humanity in the longer run.
Lion El'Jonson - The Lion was complex, to say the least. He had an arrogance that matched Fulgrim or Horus's worst moments combined with a difficult early life fighting Chaos beasts on Caliban. This "do-or-die" attitude spilled over into his interpersonal skills, hard. Too hard. Put simply, you had one chance with Johnson and if he ever decided you wasted it, then it was over and you went on his shitlist forever. The end result was a Primarch who was aloof and taciturn, whose poor communication skills made him unsuited to lead the Primarchs but whose ego made it impossible for him to accept the seniority of Horus or Russ. At the same time, there was a competitive, spiteful, and self-centered side to the Lion, which led him to execute one of his own Dark Angels over a conflict of authority and nearly kill Russ over an argument about kill-stealing. There's been speculation in-universe and out of it that he wasn't wholly loyal to the Emperor, but he made it clear to Curze that he sees loyalty as "its own reward". The only reason he's below Russ is that Russ at least admitted his own faults and tried to interact with people, while the Lion was too stubborn to admit when he was wrong and came off as distant at the best of times.
Ferrus Manus - A big dude with a penchant for bursts of choleric anger. Between his resting bitch face and his Social Darwinist ideals, he seems at first glance to be a natural candidate for a traitor. However, his honesty and loyalty to the Emperor mean he certainly wasn't as bad as Perturabo or Mortarion, and he did sincerely believe that weakness would cause the Imperium to collapse. He was... really a pain to deal with, however. Unlike, let's say, Dorn, who was only really mean when you made it on his shitlist, Ferrus was only nice to people who made it on his friendslist. Anyone else could as far as he was concerned better stay out of his way or get introduced to his fists. Most of the Loyalists and even some Traitors (at first) viewed the protection of the innocent as their goal, while Ferrus encouraged tactics that led to massive civilian casualties, and where Primarchs like Curze or Angron took Legions that were bad about mortal deaths and kept up such practices, Manus took a Legion that had tried to minimize mortal deaths and made them worse about it. All this said, he was loyal unto death to the emperor's ideals and he also understood that his sons' fetish for cybernetics was beyond unhealthy and wanted to help them overcome it. His death ensured that last part would never happen, and indeed made them double down on their hatred of the flesh.
Alpharius Omegon - Damned if anyone knows. You just can't trust that/those guy(s), which does make him/them a pretty big dick by default. The fallout from some of the Alpha Legion's Crusade-era shenanigans suggests a certain inclination to showing off at the expense of civilian lives, probably due to an enormous inferiority-superiority complex. Still, they rebelled under perhaps the best intentions among all the traitors with Alpharius at least recognising Chaos had to be defeated. Omegon is possibly a bit better, in that he wasn't willing to sacrifice all of mankind to do so. After Alpharius's probable death by Dorn at Pluto and Omegon taking his mantle to (allegedly) die at Guilliman's hands, the legion debatably turned into a schizophrenic monster, though this is better than what Fulgrim's actions turned his legion into by far.
Fulgrim - Not as much a dick as some other primarchs. Still a dick to humans and marines who didn't match his ridiculously high standards. He also can't keep a secret, betraying Konrad Curze's trust and causing him to go nuts on Dorn's face. Other than Horus and Sanguinius, was the only Primarch to really get along with all his brothers (save Jagatai, but that's his fault. Oh, Mortarion thought he was a prancing idiot. And Fulgrim considered Russ a dumb hick), and was BFFs with Ferrus Manus, of all people. That is, until he chopped his head off. Rude. Also took pride to the extremity of arrogance, hence his fall to Slaanesh.
Mortarion - Rubbed everyone the wrong way. EVERYONE, excluding Eidolon who he actually got along with somehow. Downright bigoted against psykers. He resented pretty much everyone who he felt had it easier than him. He was also notorious for using chemical and radiological terror weapons and generally not giving a fuck about who got killed by them. However, his reputation is slightly misleading. Mortarion was the Primarch who was the most driven to slay monsters and bring down tyrants, and would rather go kill more monsters than rebuild the planet. He and his Legion were almost always deployed in the most hellish and war-torn locations, so their use of chemical weapons didn't do as much damage as Morty's detractors would have you believe. Maybe not, but he'd still deploy them in almost any theatre as a matter of course. Over time, he became more and more disgusted with people's acceptance of tyrants and psykers, and became much more likely to kill everything in the vicinity of what he considered evil. Then Nurgle made him his plague-ridden bitch, at which point he decided to just take his bitterness out on everyone lacking the Plaguefather's "gifts".
Angron - Loved killing people and not much else. Most of the casualties within his legion were a result of him being a team-killing psycho because quite frankly he didn't care what he got to kill as long as he got to kill it. That said, Angron at least had an excuse for being such a rampaging dick all the time. The Butcher's Nails had effectively turned him into a half-mindless killing machine, as it actually has not just remapped but replaced parts of his brain, effectively removing from him any emotions other than pain, hatred and battle-lust. One may wonder what sort of guy he would have been without the implants, maybe someone more akin to Conan the Barbarian? Just consider even with the nails biting at his mind he became life bros with the other gladiators of Nuceria and stopped himself from killing worthy adversaries back during his life as a slave, such an act must have meant getting brain-roasted by the Butcher's Nails. But he stick to his guns despite the suffering. On top of that, he got fucked over pretty hard by Big E when they first met, so it's no wonder he went traitor the moment Horus made him an offer, we may even credit him for enduring years fighting for the Imperium instead of just getting himself killed in any of the battles. At the end of the day, Angron was probably the primarch who gave least fucks about his legion and was content to let it run itself without his leadership, although he never really wanted one to begin with. The action that places him so low on this list is the fact that he allowed the spread of Butcher's Nails throughout his Legion, despite his own hatred of the damn things and the fact they cause him so many issues, not least going psycho rage-monster most of the time; which is a pretty fucked up thing for him to condone. Perhaps he allowed it because seeing his sons with Butcher's Nails reminded him of his fallen gladiator brothers and sisters on Nuceria. Still, it's a dick move.
Perturabo - Underwent an extreme shift some time before the heresy. Initially, Pert was a fairly relaxed architect, swapping lore with Magnus and dreaming up untold wonders (we get a look at this more reasonable side during Angel Exterminatus). During the crusade, though, he and his legion were given the very shittiest jobs and the least recognition, going so far as to have the Iron Warriors' credit in a campaign handed to other legions swiped least a few times. Understandably pissed, Perturabo spiraled from a not-very-high start (he killed a random 10% of his legion when he assumed command, simply because they weren't the very best) to rock bottom, caring even less about the life of his legionaries and civilians than Mortarion. Unlike other Primarchs like Angron and Mortarion, Perturabo didn't really have that tragic of an upbringing to justify his shitty personality. And while he did have a sympathetic foster sister, Calliphone, who tried to help him cope with his dreams being belittled and court politics plaguing him in his childhood, any sympathy went out the window when he choked her to death for pointing out his flaws and foolishness causing the planet's rebellion after he devastated Olympia (even though he did cry afterwards). By the end we was just an envious, petty bastard who was always complaining whenever things didn't go his way (which was always).
Konrad Curze - Arguably the most sadistic of all primarchs, Konrad really got off to torturing people and manipulating the masses through fear. Warped as it may have been, he did at least have a sense of justice. Unfortunately, his desire to protect the innocent was eviscerated and left to die in a gutter by his desire to punish the guilty. Any ideas of mercy or decency he may have harbored had been long buried under a massive pile of flayed guts. Angron may have not really cared about his Legion, but Curze actively despised his own long before the Horus Heresy ever started. He did admit that what he had done was wrong, but instead of trying to atone for his atrocities, he used that fact he was going to be assassinated as validation of his actions. In fact, the only two things that genuinely seemed to scare him were the possibilities that the Emperor wouldn't order his death (and render his life choices meaningless)-- or even worse, be forgiven for his behavior.
Lorgar - The dude who brought this whole fucking mess into fruition. If only he had strangled Erebus and Kor Phaeron at the first mention of Chaos. Instead he decided he was going to ruin everything for everybody because nobody was on board with his kooky cult shit. He started off as a well-intentioned idealist who sought to use what he knew best to uplift humanity, religion, before the Emperor's actions on Monarchia destroyed his psyche, allowing Erebus and Kor Phaeron to let him know about the other gods who would appreciate his worship. Ironically, the Emperor was willing to put up with the Machine Cult instead of tolerating Lorgar's craft while urging him to bring worlds into the Imperium faster. While it's true he shouldn't have been treated so harshly by the Emperor (even Malcador and Guilliman privately said as much), and even though he believed Chaos was necessary for humanity to survive and continue existence, the fact that Chaos & the Horus Heresy caused the 10,000 year old Imperium to become the grimdark, bloody, corpse-littered cesspool we all know and love outweighs all of the slivers of sympathy that he might have had. To be honest, he was one of the nicest primarchs before the destruction of Monarchia, comparable to Magnus before the Burning of Prospero. Still, Lorgar is why we can't have nice things.
