Also known as "Death Lord," Mortarion, [[Primarch]] of the [[Death Guard]] (XIV legion), now [[Chaos Space Marines]]. Has an absolute hatred of psykers, a staunch believer of the Darwinistic principal, aaaand... That's basically it.

==Biography==
Mortarion was left on the plague planet [[Barbarus]] by the [[Chaos]] gods. He was found by the Overlord of Barbarus, who may or may not have been a [[Daemon]] or may have been a sorcerer of Nurgle, but whatever he was, he was a something that was less human than Mortarion. The Overlord, naming him Mortarion (to mean "Child of Death") took the infant Primarch and raised him, teaching him the arts of combat and warfare, after caging the child on a mountain top to acclimatize to the poisonous atmosphere. Mortarion's curiosity led him to leave home and set up shop in one of the human villages in a less plague-filled valley, where he simply helped with the harvest. When the village was attacked by a marauding warlord, Mortarion charged into the fray, defending his home with his scythe. After the battle was won, Mortarion taught the villagers, and other humans on Barbarus, the same lessons of warfare he had learned from his adoptive father. Soon, they were strong enough to take the fight to the warlords of Barbarus until only the Overlord remained. The Emperor showed up in a modest robe, as he feels like doing sometimes, and challenged Mortarion to slay the Overlord alone or swear loyalty to him.

Mortarion wasted no more time and went to kill his adoptive father, but he was too weak and succumbed to the poisonous upper atmosphere. Cue [[God-Emperor of Mankind|Emperor]] time and one hit kill. The Emperor stole Mortarion's kill and evil adoptive father (Mortarion resented both). 

===Great Crusade===
He was discovered 130 years into the Great Crusade and was taken to Terra, like all his other brothers were, to learn the ways of the Imperium. But unusually he was held for a bit longer on Terra than his brothers were on the reasoning that they were going to get all of the poisons and toxins out of his system, though this would obviously hit a snag since he got his armour customised to supply him with the Barbarus gases on demand ''(maybe he was dependent on them?)'', naturally all this waiting around got him a bit frustrated and annoyed.

Mortarion managed to sneak his way through the Imperial Palace and to the construction site of the future [[Golden Throne]] ''(yeah, despite being all giant and pungent, he was an excellent [[Ninja]], also evidenced by his rules below)'' When he demanded of [[Malcador the Sigillite|Malcador]] what it was, he wouldn't accept the regent's  excuses that it was nothing to concern himself over, since Mortarion knew [[Heresy|warp-tech]] when he saw it, and considered the Emperor & Malcador big giant hypocrites. The same went for his three brothers who set up the Librarius, and he didn't get on that well with the others. Apart from maybe the Khan, Mortarion had the least central role in the Crusade of all the Primarchs.

Thus Malcador revealed to Mortarion the Emperor's greater plan; which was to remove the reliance on psykers and warp travel entirely, and that they were already planning the [[Librarian|Council of Nikaea]] in advance and that Mortarion would be the one to make the case for reining it in.

Mortarion gets his own legion and swears allegiance to the big E. Weirdly, for all his dad and Malcador's worries about him, they didn't see fit to keep him fighting alongside the Emperor like (clearly sane and well-adjusted) Vulkan. After a few years of raping and pillaging those filthy Xenos he becomes best buds with [[Horus]] and that [[Konrad Curze|creepy pseudo-batman]]. He wasn't that bad of a guy, but he resented pretty much everyone whose upbringing hadn't been as awful as his, except Horus. There's a bit in Scars where he bitches and moans at Sanguinius, Jaghatai and Fulgrim about how they had it easy before snapping at the Khan that he ''doesn't resent it''. Hmm. The newly renamed Death Guard was moulded to resemble Mortarion's old army on Barbarus, as it began prioritising endurance over everything else. In combat Mortarion relied on his raw strength, which according to Jaghatai Khan, only Ferrus Manus had a hope of matching. In a primarch-on-primarch duel he just absorbed damage, tiring his opponent out.

===Horus Heresy===
When the [[Horus Heresy]] began, of all his traitor brothers, we don't quite yet know "why" Mortarion joined the Traitors since there haven't been many books with him as the protagonist. But it was presumably for [[Perturabo|ideological reasons]] rather than being outright [[Fulgrim|corrupted]], [[Angron|broken]] or [[Konrad Curze|renegade already]] since we know he already considered the [[Emperor]] and the [[Imperial Truth]] to be hypocritical. He also felt that the whole goal of the Imperium was the wrong one- viewing non-combatants as unworthy, and hating the influence that civilians began to wield post-Ullanor. Horus' rebellion promised an order based on Might Is Right, and if the Warmaster died in the process of overthrowing the Emprah, then Mortarion might get a shot at the top job. So was probably like "Yeah I won't worship Chaos, but I'll follow you anyway!" with Horus. Then again, a flashback with Malcador tells us that Mortarion might've had mental scars just as big as Curze's and Angron's, between the jail-keeper relationship with his adoptive dad, wanting to kill said foster parent, failing and watching his real dad kill said evil dad and finally finding out that his real dad was also a psyker (basically everything that Mortarion hated).

If he was telling Jaghatai the truth, in Horus he saw a leader who could give the strong freedom to dominate the galaxy, driving out the weak and impure. At the same time, Horus might not keep the throne once he got it; there would be "room to rise" when the war was over.

However, that wasn't as easy as he thought, especially when he saw just how many despised psykers, witches, and sorcerers were running around all over the place. As a last-ditch attempt to change the balance, he tried to recruit [[Jaghatai Khan]] on [[Prospero]], using the Warrior Lodges to subvert the [[White Scars]]. Being an architect of the [[Librarian|Librarius]] and a generally cool guy, the Khan told Mortarion he was an idiot and went to town on the Death Lord. Mortarion gave Jaghatai the fight of his life, but eventually ran away to take his butthurt out on the rest of the Prosperine system, all the while brooding over the Khan's taunts. He'd thrown his lot in with the thing he hated the most and now that he'd run out of allies, it was going to claim him. Scars kinda retcons the start of Mortarion's descent here- the Khan thinks that Mortarion's "power" has grown (probably psychically) and that the guy's face looks discoloured around his rebreather. Despite this, he still insisted on claiming he was the only "pure" Primarch.

Just after getting into that scrap with the Khan, he travelled to a library world that once belonged to the [[Thousand Sons]] and set about [[Exterminatus|purging it]] to find a particular person possessed by a daemon. This would prove a turning point, as he kept the daemon in order to [[Inquisition|extract knowledge on how to defeat daemons]], but ended up getting goaded into using sorcerous powers to blast the creature into a mushy pulp and declaring that he would learn all he could about his [[Daemon|enemy]] in order to learn how to [[Fail|better eradicate it]]. Which the daemon had forseen as the beginning of Mortarion's descent into [[Fifteen views of Asscrack|Nurgle's Pocket]]. The retcon continues here, as Mortarion's claims to "purity" are mocked to his face and we're told that a Chaos God has already staked a claim on him. It's also pretty clear that Mortarion's close to going nuts even before this push, as his quarters are littered with Scientific Anti-Warp Devices (AKA shit tons of charms, incantations and numerical codes which do hurt Daemons... once he starts using the Warp). Oh yeah, and he makes speeches about how destroying worlds is good for the soul.

Following this he went on a psychic binge on Molech, using the daemon prince who his old captain Ignatius Grulgor had become to wipe out entire cities. However, he also [[Awesome|took a blast from a Stormhammer cannon in the face, stayed on his feet, and destroyed the Goddamn superheavy tank.]]

Apparently the tank shell was loaded with commen sense (and admittedly with his regular author back) so Mortarion retreated from the Warp again, smashing up his trinkets, locking Grulgor away, banning sorcery again (although that only applied to his legion and he was more lenient on his allies) and generally treating the whole thing as some kind of lost weekend. His paranoia only got worse when First Captain Typhon disappeared, and then Horus assigned him the task of destroying the White Scars. Mortarion was so suspicious that he accused Horus of trying to get him killed, not appreciating that he was the only one Horus could trust to Get Shit Done in this scenario until Horus explained that the other Primarchs had [[Fulgrim|fucked off]], [[Angron|were]] [[Curze|uncontrollable]], [[Perturabo|disillusioned]], [[Alpharius|not really fans in the first place]] or were [[Lorgar|too busy pursuing personal vendetta's]].

To that end Mortarion worked alongside Eidolon of the Emperor's Children, and despite Eidolon being a glory-whore who was all for using Chaos to modify himself wherever he could while also employing sorcerers (while Mortarion's the polar opposite), the two got along really well (mostly because Mortarion made it clear Eidolon was working '''with''' him and not '''for''' him).  Surprisingly Mortarion arguably treated Eidolon better than Eidolon's own Primarch, given how Mortarion was supportive and didn't cut Eidolon's head off. The mission would have gone swimmingly, if the Scars' head psyker hadn't opened up a Webway gate. Still, Mortarion was able to break open the Khan's flagship and teleported aboard with three hundred Terminators... only to find the ship empty, with the Khan and co evacuated to another ship (admittedly Jaghatai hated doing it, feeling like he was a coward for running away). Next thing he knew, the shields came back and his force was zerg rushed by the last of the Sagyar Mazan death squads formed from disgraced White Scars. So he watched as his nemesis escaped and the warriors he'd once hoped would force the Khan to join them redeemed themselves by delaying him. And best of all? They were laughing.

And all the while, all his ships were getting grimier and the mortals were getting sicker...

Eventually he'd use Eidolon's sorcerers to locate Typhon, his first captain would kill his navigators, claiming they were secretly loyalists, and then he'd convince Mortarion that he could take them to Terra.  Why Mortarion trusted a hidden Psyker who revealed himself as his first captain after butchering the navigators who served him quite well isn't fully known yet since those books haven't been written (hopefully there's a plausible explanation). When his big ol' fleet was pimping their way to Terra, they were caught in a Warp Storm, where they had to suffer diseases which would kill anyone else. The Death Guard's legendary endurance turned against them, holding them just on the edge of death, suffering so hard that it makes a [[Dark Eldar]] torture feel like massage (no, really). Well, what would be the best way to stop the disease? [[Derp|Start the worship of the God of the Diseases, of course!]] To be fair, Typhon was already doing that- in fact, he was the one who arranged them to be caught in the warp storm in the first place. [[Nurgle]] was pleased as the Death Guard swore loyalty to him, and he ended their suffering (but made them walking sacks of meat that simply won't die, our beloved [[Plague Marines]]). Mortarion instead became... actually he didn't change all that much.  Seriously, aside from growing wings and getting a scabby face he looks nearly identical to how he used to be, even staying about the same size as before (at least until GW releases a new model that makes him as big as Magnus). [[Angron|Very different to]] [[Magnus|Nearly every other]] [[Fulgrim|Daemon Prince in the setting]].

This act of "swearing loyalty" takes on a different context when you realize that Mortarion utterly despised the Ruinous Powers (even if he may have been getting some assistance from them towards the end of the Heresy, if the events of <i>Scars</i> are to be believed) and only submitted to Nurgle because he physically couldn't suffer any longer or watch his sons do the same.  Certain fluff sources literally state that as Mortarion lay in agony he pictured himself once again defeated atop his daemon-father's lair, too weak to fight on in the face of certain death, only this time he knew the Emperor wasn't going to save him from his fate (when you consider the importance he placed on strength and the refusal to surrender, this becomes an even bigger nightmare).  And so, after a lifetime of striving to become the most grim, unstoppable motherfucker in the galaxy he crumbled when the stakes were highest, and lost his soul to Chaos, becoming everything he hated most. Grimdark.

===Post Heresy===
[[File:Mortarion,_Prince_of_Decay.jpg|200px|thumb|left|Seriously, Morty was playing Ol'Grimmy before the [[C'tan|Nightbringer]] was ever thought up! So much for originality [[GW]].]]

After Horus got his ass kicked, Mortarion made epic formations, and marched his ships (yes, marched them!) to the Eye of Terror, where they found a nice new home, known as Plague Planet, which they started decorating and uhh... "cleaning".

Long story short, him and his legion now worship [[Nurgle]] and owns his personal little planet in the [[Eye of Terror]] from which all disease and plagues in the galaxy originate. Of note, he is now a [[Daemon Prince]], so don't piss him off. He should probably work out more so as to get back into shape, but the fact that he just has to be within a few kilometers for you to die from the toxic emanations sort of renders that superfluous. Still, Typhus got bored with his dad pretty quickly, and decided to go off on a great big Getting Shit Done expedition.

The whole enslavement and broken-by-plague thing has probably hurt Mortarion's motivation a little bit. Whereas Fulgrim, Angron and Magnus all get to have some fun with their Chaos abilities, Mortarion is just stuck in a mess of self-hatred. He's basically ended up like his adoptive father, punishing all his subjects for being too weak to rebel against him- by proxy, punishing himself for his own weakness.

To his credit, he did make himself useful in the Fall of Sanctia in 437.M36 by sending an army of diseased [[Orks]] to soften the planet up, then made their corpses explode into a massive horde of Nurglings when he and the Death Guard landed, wiping out all life in less than a day. (Thanks, [[Phil Kelly|Phil]]!) It's also emerged that he helped Typhus concoct the Plague of Unbelief, which helped raise the curtain on Abaddon's 13th Black Crusade. Now if only some [[Lorgar|other]] [[Fulgrim|assholes]] would do some work every now and then...

Incidentally, did we mention that he built his fortress atop the high mountains shrouded in toxic miasma and rules over billions of slaves? You know, exactly like the Overlord of Barbarus all those millennia ago?

===The Draigo Incident===

Tl;dr: he got his ass handed to him by [[Kaldor Draigo]] who carved the name of the previous SUPREME GRAND MASTER, Geronitan, into one of Mortarion's hearts.

The longer story, as told by the Audio Drama ''Mortarion's Heart'': Geronitan more or less baited Mortarion and allowed whole sectors to die under the Primarch's massive force (every Nurgle cult and warband within 100 sectors) until he showed up at Kornovin, which was one of the few places the Grey Knights could perform the ritual to bind his soul and kill him for good.  It failed due to the fact that Geronitan forgot to wear a helmet so Mortarion just Plague Winded him to death and laughed as the entire Grey Knights Chapter cried (yes this happened.) 

Afterwards, Kaldor got elected, mostly because he's the most expendable Grand Master who's also skilled enough to fight the Death Lord. Grand Master Crom gave Kaldor a true weapon, the name The Emperor gave to Mortarion.  

After a laughably short and one sided fight, which was really just Mortarion punching Kaldor in the face over and over again, Kaldor was able to light Mortarion's cape on fire when Mortarion eventually got a hand cramp.  Mortarion paused for a second because that was his VERY favorite cape and became distracted enough to allow Kaldor to slip Mortarion's true name into the Death Lord's mind, which caused him to FUCKING EXPLODE somehow, regardless of the fact that in every other instance of true names ever the worst that can happen is your combat stats getting halved. Though it might be because in this case the name itself originated from the Emperor, and anything that has to do with the Big-E will mess up anything Daemonic big time. Kaldor then crawled over to a helpless, nearly broken in half Mortarion and wrote Geronitan's name on Mortarion's heart in magic marker.

Just more of the usual stupid Grey Knight circle jerk stuff.

As the 13th Black Crusade grinds on, rumours abound that Abbadon has finally persuaded Nurgle to set Mortarion's alarm clock and get him moving again and '''killing Imperial scum!''' 
His fans resent the implication that he's a lazy old fuck, because even though he isn't as active as [[Angron]], he still gets waaaaay more shit done than people like [[Lorgar]] or [[Perturabo]].

===Possible Plastic Model?===

With Magnus the Red getting a fucking Daemon Primarch model, rumor has it that either Mort or Angron will receive one next. Kaldor probably will show up and autograph his other heart, though As of early 2017, a supposed image of Daemon Mortarion is floating around the internet. HYPE!
[https://www.youtube.com/watch?v=BceinBiT9jQ New video] on Warhammer tv. His model is confirmed, as well as plastic plague marines! Manreaper looks [[awesome]]! Not sure what else is getting the [[Thousand_Sons | Thousand sons]] treatment though. Plastic Typhus?

| '''Mortarion:''' || 7 || 5 || 6 || 7 || 7 || 5 || 5 || 10 || 2+/4++
|}

Mortarion is a tough son of a bitch: with the Primarch rule, T/W 7, flat dice wounds like poisoned and fleshbane wound on 6's, rerollable IWND and Toughness tests, 2+ armor save and a 4+ invulnerable save, he's basically a Gargantuan Creature for all intents and purposes. He negates Maledictions affecting him or his unit on a 4+, ''(which isn't a Deny the Witch, so Adamantium Will doesn't help and you get his 5+ DtW after, though it works out to being exactly the same as nullifying them on a 3+ anyway)'', Death Guard gain Stubborn and Poisoned (4+) on all frag grenades and missiles which is pretty sickening. For weapons he has the Lantern pistol which is almost a pistol meltagun, phosfex bombs (an unlimited supply of them, and he can throw them at double the range!), frag grenades and Silence, a S7  AP 2 no longer unwieldy power scythe with sweep attacks that causes Instant Death and reroll failed penetration rolls. Great for getting rid of that annoying Praetor or captain. Notably; he's also one of the only characters in fiction who know how the hell you're supposed to hold a scythe!.

Not enough for you? Good, because they also gave him the Shadow Of The Reaper rule. It makes enemy units take a fear check at -1 leadership. By itself in normal 40k rules, it's situationally great, making it pretty mediocre on the whole, but in the pre-ATSKNF 30k setting, it's much more useful. But much more importantly, it gives him a special move in the shooting phase: if Mortarion isn't locked in combat or embarked and doesn't shoot or run, he can take a leadership test and teleport 10 inches away from his current position. It does not count as moving, does not scatter, and does not prevent him from charging (But he does count as making a disordered charge. Not that big of a problem, seriously). There are some other caveats, but he effectively has a minimum 18" charge range without factoring in his base size, and he is fleet to boot. [[Awesome|Because he's fucking terrifying.]]

Mortarion is among the top 3 best Primarchs for his points, as SotR lets him reach combat by turn 2 unless you fail your Ld test. Furthermore, Stubborn is an absolute game-changer in 30k, as it drastically reduces your odds of breaking in Assault and Poisoned allows you to functionally ignore [[Iron Hands|certain legions]] [[Imperial Fists|Toughness shenanigans]] (and it makes it easier to hurt Mechanicus). He doesn't really need a transport or retinue, giving you more points to put towards dakka, and provided you're smart enough to avoid concentrated AP2 you're very likely to see the end of the game. He can't fight Land Raiders, but with 5 S7 Sunder attacks you shouldn't underestimate his ability to fuck up Dreadnoughts. Ultimately, his biggest strength is that unlike [[Angron]] or [[Vulkan]] he is an effective force multiplier who gives a lot to his army while needing almost no support in return.

His model is equally as badass as his rules, if you can get past that he doesn't have a rebreather (it's a part of his armors chest piece now though, but still begs the question on why not just give him a rebreather and shut fa/tg/uys up on the subject?). Although the designer probably thought that he didn't really need to breathe, and he's probably immune to anything poisonous anyway (on Prospero the Khan had to go in totally suited up, whereas the Death Lord just strolled in dressed just the same as normal, and Girlyman established that Primarchs can breathe in an incredibly thin atmosphere - he can apparently fight in near-vacuum for hours on end without a helmet, because [[Heresy|fuck physics]]). (Even in-universe, Guilliman's ability to fight in the void without a helmet and little oxygen has Imperial scholars going "WTF?")

==Mortarion VS other Primarchs:==
<div class="toccolours mw-collapsible mw-collapsed" style="100%">
Primarch fighting, while fun to see isn't a very competitive thing to do as it'll usually tie up both Primarchs for the entire game without either of them dying (especially with Mortarion who can mathematically always go the entire game in a Primarch duel), with that in mind this section is how Mortarion fares against other Primarchs Mathhammer wise.  Please note that all the various abilities, with the exception of Blind, are taken into account (Blind is ignored because it never changes the outcome of the fights, the winner is still the winner with or without it) and the match-ups assume the Primarchs are the only ones involved in the fighting, so various abilities like Angron's "The Butcher's Nails" and Rampage do not provide any bonuses.

**Mortarion wins either way in this fight, he causes more overall damage, has more wounds, and regenerates faster.  In addition even if Corax runs away Mortarion's ability to teleport will mean he'd catch Corax very quickly after he re-appears so he cannot run away to heal which would render this a stalemate. 
**Note: Corax could attempt to "cheat" his way to victory thanks to his special rules, especially Sire of the Raven Guard (which grants him Super-Furious Charge) and Hit & Run. With this he could disengage at the end of Mortarion's assault phase, in order to charge him again during his turn. Using this tactic he would Shoot with his pistols for 1.9444 hits, 0.648 wounds, 0.108 wounds after saves, then charge in with Hammer of Wrath gaining 0.333 wounds, and 0.0555 wounds after saves, then attack with the Panoply which hits 4.5 times (scourge), wounds 3.375 times, 1.6875 after saves and 1.132 with IWND for a total of 1.296 Wounds.  This, combined with Shadow-walk during Mortarion's assault phase in order to mitigate his retaliation barely lets Corax win if he goes charging scourge in round 7, then scourge again in round 8 as he strikes before Mortarion, compared to 8 rounds needed for Mortarion to kill Corvus (this is including Overwatch with The Lantern).
**Though this looks like a close fight at first glance, this tactic relies completely on Hit and Run (which is more akin to Corvus's fighting style), as well as assumes the Charging always works out in Corvus's favour and so the strategy will mathematically fail over the eight rounds needed to kill Mortarion (as there's mathematically one turn that either Hit and Run or Charging will fail when Mortarion consolidates away from Corvus's consolidation) giving the victory to Mortarion again. But that's actually the same chance of Corax Blinding Mortarion (Not included in the fights), so the odds are still the same.

* Mortarion VS Roboute Guilliman
**Round 1: Guilliman hits 2.5 times, wounds 2.083 times (With Hand of Dominion), 1.042 after saves, and IWND take it down to 0.486.
**Round 2 and after: Guilliman hits 3.333 times (Thanks to Preternatura Strategy), wounds 2.777 times, 1.388 times after saves and  IWND will take that down to 0.833.
**Mortarion hits 2.5 times, wounds 1.666, 0,833 after saves, 0.417 wounds after Armor of Reason, and after IWND they become 0.083 wounds.
**Guilliman wins in 8 turns as Mortarion's damage is almost irrelevant.

* TLDR version: Mortarion's good against Konrad Curze, Vanilla Lorgar, Hammerless Perturabo, Alpharius, Rogal Dorn, Corvus Corax and bad against Horus, Angron, Fulgrim, Ferrus, Lorgar Transfigured, Vulkan, Perturabo with Hammer and Guilliman, putting him quite in the middle of the road for Primarch duelling.

* Dirty Trick: Use Morturg and put Endurance on Mortarion, if you do this Mortarion can beat everyone (including Lorgar Transfigured) except Horus, Fulgrim (with Fireblade) and Vulkan as his damage output will exceed theirs or his extra wound will allow him to outlast them and/or they will be unable to hurt him at all mathematically.  The reason Horus Vulkan and Fulgrim still win is because Mortarion will eventually be unable to hurt Horus thanks to Disabling Strike, Fulgrim just causes too much damage (and some of his attacks ignore FnP) and Vulkan's Instant Death hammer ignores FnP.
