Power Armour

This page is needs images. Help plz.

Power Armour is a science fiction concept of armor which increases the strength, speed, and reflexes of those who wear it. It features heavily in science fiction/fantasy settings such as Warhammer 40,000.

Starship Troopers

Like so many military science-fiction concepts, the modern idea of powered armor dates back to the Mobile Infantry of Heinlein's Starship Troopers. The "Marauder" suit is bulky, with integrated thrusters and heavy weapons (including nuclear weapons and heavy explosives, carried as easily as a human soldier carries grenades). Their primary purpose is not to destroy indiscriminately (though they certainly can), but to "make war as personal as a punch on the nose" -- to drop in and destroy with precision, in order to break the enemy in exactly the right way. In other words, it's much like Crisis battlesuits with less weeaboo and more humanity fuck yeah inside.

Heinlein never discusses pauldrons, but the Space Marines certainly take after the Mobile Infantry's other aspects.

Warhammer 40,000

Because 40k has a huge hard on for Space Marines, and because no super soldier worth his genetic enhancements will go into battle without super armaments, 40k has developed nearly as large a hard on for power armor. In a moment of honest good idea from GW most of the power armor in 40k is made from ceramic, which is known for being brittle but highly resistant to heat, while the most common infantry weapon in the setting is the Lasgun, which while not overly powerful to begin with, works by imparting heat to a target meaning space marine power armor is remarkable well designed coming from a company that has made massive mechanical design issues in it's equipment (see leman russ) to begin with.

Space Marine Power Armour

The most iconic users of Power Armour in 40k are the Space Marines and the Chaos Space Marines. Made of ceramite layers upon plates of plasteel and adamantium/adamantine which will deflect all but the most powerful of weapons, Power Armour possess many life support systems designed to keep the Space Marine inside alive, even in the worst and most extreme of battlefield conditions.

The Black Carapace, one of the Gene-Seed organs, is specially designed to allow a space marine to mentally interface with his powered armor suit, and is the last organ implanted in Codex Chapters. Amongst its features, Power Armour possess auto-senses which enhance the Marine's already considerable senses, auspexes which create minimaps and transmit data, injects pain killers in the event of lost limbs, and recycles the waste of the body into a nutrient paste which will keep the Marine going for up to fifty days without needing to eat again. The power source is a backpack mounted generator which needs initializing, but after that can take solar energy to keep itself going.

There are eight types or Marks of Power Armour used by the Astartes. Regardless of their type, they all have massive Pauldrons.

Pictures can be found in the Gallery at the bottom of the page.

Mark I: Thunder Armour

The first type of Power Armour designed, these were used by the Thunder Warriors and many of the techno-barbarians of Terra. They provided the basic protection against weapons and enhancements to upper-body strength, but that is all - the suit was incapable of supporting its own weight and did not provide any protection to the legs. Since they were only used on Terra, there was no need to protect them against the void. Though the lack of life support systems and much lesser degree of protection make them essentially useless in the 41st millennium, several Chapters retain sets of Thunder Armour as ceremonial pieces of armour. If you were to field one now, it would probably count as Carapace Armor (4+ save) with a slight bonus to strength but a penalty to initiative.

In Deathwatch, if you can actually get your hands on some, it's noisy, doesn't offer as much protection, doesn't work with a Marine's Black Carapace, and actually might not be a whole suit of armor depending on its state of repair; in short: overall it's kind of shitty. But a surviving artifact linked to the early days of the Emperor does impress other Marines and the Ecclesiarchy schlubs, so take it for formal occasions.

Mark II: Crusade Armour

Designed by the Adeptus Mechanicus with the Great Crusade in mind, the Mark II armour was fully enclosed and contained all the life support and auxiliary systems now common among Astartes power armor, like a waste recycling unit and automated medical equipment. Much of these newer additions were made possible by a more efficient cooling system, which allowed a considerable reduction in the size of the powerpack. The helmet also came with a bunch of enhanced sensory equipment, but was bolted directly onto the armour, preventing the wearer from turning his head. Overall protection and flexibility was much improved, especially since the legs were now enclosed in armoured hoops and came with their own servomotors. Unlike the Mark I suit, the design is still sufficiently sound to remain in active, albeit extremely limited, use well into the 41st millennium.

Mark III: Iron Armour

Mark III armour was first conceived for ~~the Squat campaigns~~ boarding actions of the Great Crusade. It was pretty much a modified Mark II designed to provide better frontal protection for close quarters combat, essentially fulfilling the same role that Terminator armour would later fulfill. By the time of the Horus Heresy, the Mark III was slowly being phased out and replaced by Terminator armour, but it's still fairly common among the Traitor Legions. In fact, several of the more traditional Legions were reluctant to phase out Mark III armour because it was the most brutally iconic Mark of Power Armour in their day, so there was talk of keeping it for honour guards or spear tip operations. Even into M41 the helmet or faceplate is still popular.

Mark IV: Imperial Maximus Suit

Now having access to more of the Standard Template Constructs, the Mechanicum was able to further refine power armour internal systems. In addition to having more advanced visual sensors, the helmet was now capable of movement. The suit was also made a whole lot lighter than before while managing to further improve on the Mark II's protective capabilities. Although the chest power cables were once again relocated to the outside of the plating, they were given an armoured sheath to protect them from damage. Horus Lupercal manipulated the Mechanicum's supply lines to ensure that the Legions that were planning to side with him in the Heresy would be fully equipped with Maximus Armour in time for the Heresy; as a result Mark IV was usually reserved for Chapter Masters and senior Captains of the Loyalist Legions. As the Legions were either fully or partially re-equipped with these suits by the time the Horus Heresy began, Mark IV is one of the most prevalent types of armour among the Chaos Space Marines.

Mark V: Heresy Armour

In between production of the Mark IV and what would be the Mark VI, both Loyalist and Traitor Legions found that they were running out of replacement parts for damaged systems. This would result in several Legions taking parts from older Marks and inadvertently making a brand new Mark of Power Armour. Although appearances varied widely as a result of its adhoc nature, some form of standardization was achieved. One of the most notable was the introduction of molecular bonding studs on the left pauldron and both greaves, which made them look totally Metal. Probably one of the most common suits of armour in service among the Traitor Legions, since this was what most of them were wearing when they retreated to the Eye of Terror.

Mark VI: Corvus Armour

The much beloved Beakie armour. Designed as a stopgap measure while newer equipment remained in development, it incorporates some of the newly developed Mark VII features into the battle-proven Mark IV design, producing a suit of armour that is in many ways equal to its descendants. Although it offered no additional protection, Mark VI armour was the first to feature a redundant power system and parts that are slightly interchangeable with those of other marks. Somehow, it also manages to be lighter and fit together more smoothly than the current Mark VII Aquila, allowing for quieter movement, while the helmet includes further improved sensor systems in its, um, "beak". It was named the "Corvus" pattern after Primarch Corvus Corax of the Raven Guard, as the XIX Legion was the first to be selected for field testing the armour. Due to the design's inherent stealthiness and legacy, it still remains the preferred armour among the Sons of Corax, who tend to be saddled with older equipment anyhow.

Mark VII: Aquila/Imperator Armour

The most common Mark of Power Armour among loyalist Space Marines, Mark VII armor was still being designed when the Traitor Legions reached the Sol System and seized Mars. When this fact became all too foreseeable, Rogal Dorn ordered the design teams transferred to Terra to prevent the Traitors from seizing it. Mark VII featured completely covered chest and arm cabling, a distinct helmet that provided more protection, a high level of compatibility with the previous Marks, and also bore the Imperial Aquila on the chest, which was first used there to provide quick identification of the Loyalist Marines during the chaos of the Siege of Terra.

Mark VIII: Errant Armour

Jes Goodwin originally designed it with awesome Power Fist-style hands, a modified helmet, a streamlined power pack and a more flexible leg-and-ankle joint. Games Workshop only bothered with using the altered breastplate, so the overall design looks like a regular Mark VII with a collar. Breaking the trend of reverse-compatibility between newer and older marks, this Mark can only accommodate the helmet designed for it, which kind of becomes a moot point when reserving it for officers, since everyone higher up than a battle brother will never wear his helmet. The specialist design, or the Adeptus Mechanicus' head-up-own-arse tendencies around distributing new technology, are thought to be the probable reasons why it has yet to be widely adopted among Space Marine chapters. Because of its rarity, the armour is generally restricted for use by senior officers only, and even then they'll usually only be able to wear the breastplate. The Minotaurs chapter appears to be the only exception here, as almost all of their battle brothers have access to full suits of armour.

It should be noted that, while Artificer Armor, at least in the art, looks like a pimped out Mk.VIII, the Minotaurs show us that Errant Armor in fact doesn't improve armor save. Artificer Armor, then, is a customized version of any later mark, without any seriously improved protection going into the Mk.VIII on its own.

Chaos Power Armour

While many Traitor Marines are equipped with Marks IV or later, Chaos power armor is often a mix-and-match setup. Because Chaos Marines often have to go long periods with no access to proper industrial facilities, proper maintenance and replacement parts became an issue. Because of that, many subsystems in each suit of armor don't work and replacement parts come in the form of whatever they can dig up from plunder and taken off of corpses after raiding and looting. Furthermore, Chaos Marines like to customize their armor with devotional iconography and personal trophies, making sure that virtually each suit of armor is personalized and none are exactly alike. Where things get even weirder is when armor gets too steeped in Chaos and begins to twist, mutate, and turns partially organic, or has its machine spirit replaced with a daemon. Recent editions and artwork show senior Chaos marines with a sinister, more organic looking power armour being something they pick up after a while.

(Originally in the Rogue Trader Era, Chaos Power armor WAS organic, so this is actually a pleasant return to the old days.)

Praetor Power Armour

Before the Heresy, the Ultramarines made their own pattern of Power Armour called Praetor-pattern. It was locally produced at Veridia Forge on Calth. It was easier to produce than Mark IV, and easier to maintain, but not quite as advanced. Think of it somewhere less than Mark IV but superior to the average Mark V.

Terminator Armour

Set aside for space marines who are exemplars of toughness, martial ability, and wonky proportions, Terminator armor, or Tactical Dreadnought armor, provides the best personal protection available. Heavily layered with adamantium and indestructible pauldrons, a suit of Terminator armor is meant to steamroll nearly everything, and gives a fighting chance against everything else, which is anything that gives anybody else a fighting chance against Terminators. Standard loadout for Terminators are power fists and storm bolters or Power weapons and twin linked bolters for the Chaos variant, but they are able to fit a shoulder-mount missile rack, equip heavy weapons systems, and arm with other killtastic melee weapons. Since most suits are about at least as old as the chapter that owns them, and that the pauldron allegedly contains a tiny fragment of the Emperor's own power armor, these suits are holy relics as well as top-quality wargear.

Despite all the pain they lay down (and keep away), Terminator armor has a few serious drawbacks. First thing is that it is seriously hard to make. Seriously. Most chapters have a only handful that they can distribute amongst their veterans and officers, and any lost suits are damn near irreplaceable. Second thing is that they lack mobility. They counter this mostly since Terminator armor can teleport into the thick of it, and judicious use of teleport homers can put them right where you need them, and a Land Raider can carry small squads;. Beyond that, Terminators are otherwise going to be footslogging since they're too fucking huge to hitch a ride on anything smaller than a house. Unless you're fighting a fast or a crafty opponent, you won't care anyways.

Terminator Armor had 3 major designs- The Cataphractii, the Tartaros, and the Indomitus Pattern. The Cataphractii was the first run at Terminator armor, developed after the mk III power armor and sharing many systems. Bearing much larger power field generators and thicker armor, it provided better protection than future variants, but was much more unwieldy and difficult to use. The Tartaros patter shared many of it's systems with the mk IV power armor, and was much more maneuverable than it's predecessor, at the cost of some protection. The Indomitus pattern is the current pattern of terminator armor, sharing similarities with the Tartaros pattern in therms of functionality, but is based of a design being tested during the heresy by the Iron Hands legion.

Centurion Armour

Since somebody at GW forgot that the Xzibit meme wasn't funny anymore, Space Marines now have Centurion armor that they equip like a miniature walker vehicle, more like a mini-mech, a cute little dreadnought preparing space marines for their life after living. Centurion armour is "worn" over regular power armor, giving better protection (like terminator armor without the invul save) and comes in two flavors: assault and devastator. Assault Centurions are heavy assault units equipped with drills and meltas or flamers, meant to get in close to enemy strongpoints and fortifications and wreck shit. Devastator units are a heavy fire support units with hurricane bolters and twin-linked heavy weapons, which is in practice, a bit less effective than Devastators.

Aegis Armour

The Power Armour of the Grey Knights, Aegis Armour is master-crafted on the forges of Titan and inscribed with prayers and wards to prevent Daemons from possessing it. Based on parts from Marks VI, VII, and VIII, within the breastplate of each set is a copy of the Liber Daemonica. It frequently bears a stormbolter on its left forearm, keeping both hands of the wearer free to use. There is an Aegis/Grey Knight version of Terminator and Dreadnought armours, too.

Warhammer 40000: Space Marine

In Warhammer 40000: Space Marine, the Marines are wearing what looks like regular Mark VII Aquila Armor. However, it appears to be far less bulky in comparison to similar armor portrayed in official artwork or Dawn of War, suggesting it might be different. For one thing, it appears to be much more streamlined, with lower pauldrons that aren't quite as fucking enormous (although still unrealistically huge), and with more head room and mobility in the arm sections. This becomes very apparent when using ranged weapons, like the Bolter. This streamlining was likely done to avoid hilarious amounts of clipping. Judging by the fact that every other suit of Imperial power armour in the game - Chaos included - shares this appearance, it is probable that it is simply a reimagining, or a 'realistic version' of regular Space Marine armour. It's not like the Space Marine game is the first artwork to portray power armour with different proportions to other media.

Human Power Armour

Virtually identical to Space Marine power armor, these suits of armor are scaled down to fit regular humans (notice that this is the reverse of what it would have been 10,000 years ago). Human power armour is relatively quite rare, since it occurred to somebody that making good protection being an affordable and wide-spread asset would severely impinge on the current state of grimdark.

Without the extra room and black carapace interface Marine armor provides, many suits of human power armor don't offer the same degree of protection, as much strength enhancement, or as many subsystems found in Marine armor. Still, the wearer will still be stronger, better protected, and better equipped than the guy in the T-shirt. There are a few variants, including a lighter suit and one for Chaos-fighting Inquisitors. Because these things are still super-rare, usually only people rolling in money, tech fetishists, and those able to declare not giving them power armor is heresy, will have any.

Sisters of Battle Armour

Less bulky than the Space Marine armour, as they're worn by normal sized humans. Despite Astartes & Sororitas armour both giving 3+ saves on the tabletops, in actuality the power armour of the Orders Militant of the Adepta Sororitas provides lesser ballistic protection that Space Marine armour does. The identical in-game protection is mostly because saves in 40k are decided on numbers between 2-6, so there aren't as many gradients in-between.

They also do not provide the same level of strength enhancement, though they do give them the strength to carry heavy bolters (and their ammunition) into combat and fire them without shattering their arms. Sororitas armor has noticeably smaller pauldrons, the leading idea behind this reasoning was incorporating a design feature that cuts back on the material it takes to create this variant, without having to sacrifice the pair of perky, globular breasts.

Helmets are NOT included as standard either, mostly because the majority of Sororitas models have distinctive haircuts, but according to Dark Heresy, the Sisters of Battle do not receive their helms until about halfway through their careers, making it the inverse of the policy held by the Astartes where higher ranking officers are more likely to lose their helmets instead.

The advantage of Sororitas power armour, though, when compared to all other human-scales of power amour, is that it runs off of the same fusion reactor that Astartes armour does, and therefore can run indefinitely, rather than for a few hours at a time. Another advantage is that it is not as bulky so it does not turn the wearer into a big giant target either.

Dragon Scale Armour

Dragon scale armor is basically Mechanicum power armour, commonly used by militant Enginseers of Imperial Guard and Myrmidon warrior priests of the Ordo Secutor. It does not have an external power source, as it derives power from Mechanicus implants (and therefore cannot be used by anyone outside the tech-priesthood or high-ranking Skitarii). Not as thick as Astartes power armour, it sports many more inbuilt devices and sensors and gets further pimped by the Techpriest wearing it as he progresses through the ranks of the Adeptus Mechanicus to the point where it's hard to tell where the armour ends and its wearer begins. Some wonder if it is connected to the Void Dragon.

Fallout Power Armor

Unlike Warhammer 40,000, Fallout powered armor is more "power" than "armor". It was originally made to allow troops to use heavy weapons on the move and with increased weight limit it was obvious to put some extra armor on the exo-suit. Even while it turns you into a nearly-indestructible walking tank, sneaking and camouflage are always considered better protection than armor in Fallout, so the main reason people use it is strength and radiation resistance bonuses.

T-51b Powered Armor

This armor only has +1 STR for some reason. What's even stranger is that the hunk of metal that you put on your head (AKA the helmet, but who calls it that?) gives you a +1 CHR bonus (probably because its heavily featured in old world propaganda, but yet again, so was the T-45d variant) . We really should be wearing around hunks of metal on our heads these days. After all, this armour be pullin' all dem bitches...

T-45d Powered Armor

After Bethesda got the rights to make Fallout 3, they were like "Guys, guys, let's make a SHITTY POWER ARMOR!" and they went through with it. The result was far from shitty. Sure, it has -2 AGL, less rad. resistance and makes you move around like ~~yo madda~~ the comic book guy from The Simpsons, but it looks BAD-ASS!!!

NCR Salvaged Powered Armour

This is the 'zombie' version of the T-45d Powered Armour. It has had all of what made it power armour ripped out by the NCR (because in New Vegas, they don't really teach you how to drive a suit of power armour) so now it's just a cool looking variant of metal armour with paint splashed on it (because NCR for the win!).

Advanced Powered Armor

The 2nd most advanced power armor and the newest, made by the Enclave who still have much of the pre-war resources. As a result it has little of the flaws of the older armours (T-45d and T51b models) while being better in every way. Save for the next power armour listed.

Advanced Powered Armor MK II/Enclave Powered Armor

Because advanced power armor wasn't good enough for the Enclave, Advanced Powered armor MK II was made. This is the armor that is featured in New Vegas, and while the NV variant kinda sucked, The variant in the 2nd game was OP (yet again, so was all the other power armors, but what the hell. OP for the win!). Although Bethesda fucked it up and made T-51b better. It was fixed in New Vegas (Although for some reason the power armor in NV is a 'medium' armor and degrades like it was made of cheap Chinese plastic).

StarCraft Power Armor

In StarCraft, the Confederate Marine Corps Power Armor, more simply called the CMC power armor, is the standard powered armor suit used by all military factions within the Koprulu sector. Despite the fact that each armored suit comprises a complex array of sensors and other advanced combat technologies, life-support systems, and its own independent power supply that appears to be a portable fusion reactor, it seems to be dirt-cheap as hell to manufacture, given that every armed force within the Koprulu sector can give one of these suits to every Terran marine worth a damn. Unfortunately, that technology doesn't seem to grant much actual protection; the marines are usually unceremoniously wiped out by the ~~dozens~~ hundreds during an engagement.

Along with that, however, it's not exactly known if the armor plating on the suit can protect the wearer from actual combat damage. The CMC armor is incapable of reliably protecting the wearer from projectiles, ruptures, or chemical attacks (apart from the passive hazards found in NBC environments), in both fluff and crunch, considering that it cannot hope hold out against: zergling claws, roach acid, the Marines' own gauss guns (hell, it can't even deflect the pistol rounds from their sidearms), fire and/or plasma, hydralisk spines, Mutalisk wurms, Psi attacks, Protoss photon guns, and really just about anything. Then again even tanks, huge giant robots and battlecruisers could not hold against said attacks en masse - this might say more about how nasty are weapons in StarCraft universe rather than how shitty is armor there, or more likely it's how real world armor works. In fact, some of the fluff describes it as existing more to protect the wearer from the recoil of the Gauss than anything else. In addition, Starcraft armor is primarily ablative - no armor in the game renders anything in the game immune to damage. In Heart of the Swarm game terms, consider a fully upgraded marine, marauder, reaper, and ghost:

The marine has 55 hit points and armor 3. On a per-hit basis, he takes 6 damage from a marine's assault rifle, 4 from a reaper's pistol,10 from a marauder's grenade launcher, 23 from a ghost's sniper rifle, and 25 from the sniper rifle when the ghost psionically charges the round. The reaper is almost identical, but his armor is thicker - he has 60 hit points, so it takes 2 more pistol rounds (one more salvo, since they fire both pistols at once) to put him down. The ghost's armor is substantially more impressive. Not only does he have 100 hit points, he takes less *base* damage from sniper rifles - 10, rather than 23, so it takes 10 sniper rounds, not 3, to kill him. However, he takes extra damage from psionically charged rounds - 50, enough to kill him in a mere 2 rounds. The marauder has the thickest armor of the lot: 125 hit points and armor 4, with reduced sniper damage - but his armor is weak to grenades. His spread is 5 from the assault rifle, 3 from the pistol, 9 from the sniper rifle base, 25 from empowered sniper rounds, and 22 from the grenade launcher. This means he'll die in 6 grenades like a marine or reaper, compared to the ghost dying in 10 grenades, but will last much longer against the other three weapons.

Other variants exist that are worn by Firebats. The armor is much bulkier than the standard armor, which keep in mind was already similar in size to terminator armor, especially in Starcraft II, where the thing's arms and pauldrons are bigger than its legs. Since the the armor's bulk makes it thicker, it can take far more abuse than the regular armor. As the name of unit might indicate, the armor uses a pair of built-in flamethrowers. The armor worn by Marauders in Starcraft II looks almost identical apart from a change in color, and has the same durability, but in place of flamethrowers uses grenade launchers that are best used against armor. Despite the armors' size (and concomitantly longer legs), the guys using them are just as slow as regular marines. A third type of armor is made for Reapers, which looks similar to Assault Marines except their jetpacks are bigger.

Less well known, but still present, is the armor worn by the Protoss. It doesn't cover the entire body like the Terran armor does, but it still provides greater protection given that provides regenerating energy shields, and is actually durable enough provide protection from the common Terran and Zerg weapons, and despite not covering the head it does still allow the wearer to perfectly function in a vacuum and protect against environmental hazards. The other mean feature on are it are the built in psi blades (basically lightsabers) in its arms, which in lore, can slice through most anything, with only Kerrigan's bladed wings being able to stand up to them. All the features on draw power from the wearer's innate psionic, meaning it can function for much longer periods than Terran suits, potentially indefinitely as long as the wearer survives. This, is on top of the fact that the protoss without any armor have shown themselves to be more survivable than Terrans in there's. Also has a built in teleported to not only allows a Protross to pop into but if badly wounded enough sends them away to be saved.

Metroid Power Armor

Probably one of the most powerful armor on this list. Like Starcraft, pretty much every scrub gets a power suit in Metroid, but the main character's suit is the one you probably want to know about. Samus Aran's armor is like a wearable, form fitting Titan, designed on a planet that weighs nearly a thousand times more than the earth that fires out basic weapons shots that carry more energy than small nuclear weapons. But that's not all, it's ridiculously modular and can accept pretty much any piece of technology ever and turn it into an upgrade, even if the Chozo had never once encountered the technology in question!

When fully upgraded to end-game status, the Chozo suit shits all over almost every other suits here like a pigeon with precision diarrhea.

The only really flaw in its design is that it is stupid easy to knock all of its power ups and reset to default -- Samus never manages to hold onto her upgrades between games. Like all Power Armours worth their name it also has pauldrons, although not as ridiculously huge ones as the most other armours on this list.

Halo Power Armor

Most people think of the Spartan power armor when they are asked about Halo. These suits cost as much as a UNSC ship and have the decency to protect the wearer from multiple Fuel Rod shots, despite being penetrated by a single pistol shot...inconsistency aside the Spartan power armor is in between the strengths of a Astartes power armor and the Terran power armor. Unlike most other armors, the enhanced speed and strength given by these things is too much for an ordinary human; anybody other than the Spartans, who underwent genetic enhancements, ends up getting mutilated in the armor just by trying to move in it. Other power armor in Halo includes both the Brute and Elite combat harness which boosts their already insane strength (twice that of a human of the same mass for elites, about two or so tons for a Brute) and reaction time (although Brutes tend to be a bit more sluggish than humans).

More noteworthy perhaps for the fact it does not cost as much as a spacecraft, does not have pauldrons the size of the user's head and is implied to be halfway to efficient or practical(if you took away its active ingredient, the shield generator) and is used by the SAS in SPEHSS is the ODST armour, which has both better data analyst equipment than the MJOLNIR and suspiciously similar play style to the piece of junk used in halo 1.

Of course there are the Forerunner Combat-Skins, but putting them here on the list would shit over any power armor listed there, that are not near Metroid grade. How powerful are they? Enough that they could shrug off multiple melta-level bombs, fall off and survive a Slipspace rift without a scratch, tanking weapons that could dwarf most WH40K, Starcraft and Halo small-arms altogether, can command up to a million attack drones, and can shut-off your brain like a switch. However, in a setting where battlefleets can blow up planets and combat mechs can level cities (which are the size of continents), they are very tame in comparison.

It is also worth noting that Forerunner armor comes in mini-mecha and form-fitting varieties. Most of the above is for the mini-mecha, while form-fitting armor seems to be substantially less impressive.

Metal Gear Exoskeleton

The Metal Gear series has featured exosuits throughout the series. While not very /tg/-ish, they do deserve a spot on this list for being either balls-out wacky to Complete awesome.

Solidus' Powered armor

Solidus Snake, the third clone of the Sons of Big Boss, has a powered armor suit that allows him to enlarge his muscles at will, enhancing his strength and speed. He can also shrink them back down to allow him to fit into smaller spaces or appear naturally. It also has a pair of tentacles to shoot missiles and choke people..

Cyborg Exosuits

After the fall of the patriots, cyborg technology became prevalent. With CNT muscle fiber being as cheap to produce as plastic; just about every mercenary worth a damn opted to be augmented and encased in one of these things. Pioneered by The Patriots, the armor enhances the wearer's strength, agility, and survivability to absurd levels; turning them into an unstoppable murder machine that will completely wreck the shit out of anything it faces.

The caveat to this is that majority of cyborgs are unwilling participants or balls-to-the-wall insane, turning them into blood-crazed maniacs in one way or another. Gray Fox, the original recipient of this armor, was resurrected from the dead against his will and became a guinea pig for further experimentation in grafting exoskeletons onto people, particularly finding no reason to live and suffering painful feedback effects from the imperfect system.

Raiden, the more popular surviving recipient, along with most of the other cyborgs made after him; were captured against their will, had nothing but their brains removed from their human bodies and had what's left of their head and brain placed on a cyborg body. A special note also goes to Raiden (AKA: Jack the Ripper), who's known to throw titan-sized Metal Gears into the air before slicing them to ribbons before they land. Other lulzy feats include fighting, suplexing, and ripping the arm off a Metal Gear the size of a Tyranid Biotitan to engage it in a duel and destroy it.

Iron man's suit

Probably the most well known Power Armor suit in fiction. At its high end, Iron man's suit is flat out superior to anything in nonserialized science fiction short of a few cheese builds from role playing games, but hey comic books, even allowing him to fight Odinforce Thor, who mind you, has the power of a being who can destroy galaxies as the side effect of his fights. Sure his standard suits may be beaten by weaker stuff but if he really sets his mind to it, the things Tony can build are essentially magic contained in metal and get shit done!

Destroyer Armor

Perhaps the snazziest and most powerful armor in fiction. This creation of Odin (Marvel Universe version) cannot be damaged by anything less powerful than Odin himself and can destroy just about anything weaker than Odin in a single hit. Forerunner suit, Chozo suit? HAH. This is made by gods who actually feel godlike. Crafted by someone who could eradicate entire galaxies as a side effect of his fights to battle even more powerful beings. Accept no substitutes, this is the finest power armor you'll ever find that does not ascend you to Celestial wonkyness. Even if it does run on magic.

Humorously, the things it was design for, to fight Celestials fails as they just one shot it the second it shows up.

Strike Legion

Strike Legion has teraton pistols, Uzis that can outgun all of WH40K and planet busting grenades. You can survive those in one of these babies. Like a bauss. Even the weakest ones have built in shield generators and flight capabilities. That is really all that needs to be said. They are also mass produced. Like, standard issue level mass produced. By factions that can outnumber the Imperium of Man.

X-COM

A trio of MEC troopers with kinetic pilebunker fists and minigun. Yes, you can make your own Terminator squad using MEC upgrades.

X-COM always had high-tech armor, but only two of these were actual power armored suits in the first game. The first one is the "Titan" armored suit, a heavy personal powered armor suit composed of alien alloys. These could drastically reduce damage, give the wearer increased strength and stamina, and were fully sealed from the outside-environment and had an array life-support systems, so the wearer was immune to poison, fire, and getting chocked to death. The other is the "Archangel" armor, while only about as durable as medium carapace armor, it instead sported a personal jetpack that allowed the user to hover and fly for limited amounts of time until they ran out of fuel. It was still sealed and possessed the same life support systems as the Titan armor.

However, in the Enemy Within expansion to the 2012 remake. This came in the form Mechanized Exoskeleton Cybersuit troopers, or "MECs" for short. Departing from the usual type of armor, these require a considerable amount of cybernetic enhancements through the use of the game's Meld resource to use, which in game is shown in that MEC troopers have much of their body replaced with cybernetics (they basically look like smaller version of Robocop, minus the helmet) to interface with MECs; Giant powered-armor suits capable of carrying an array of powerful weapons, one of which is a giant fist weapon that can insta-kill just about almost anything it hits.

The pay-off far that is enormous, however. Unlike other low ranking soldiers in X-COM, the MEC troopers are extremely durable (to compensate for their size meaning they can't use cover.), and can use the most powerful guns in the game, that only the MEC's strength and durability allows them to use. Additionally, additional rank-up abilities and suit upgrades will further make MECs much more lethal as they progress through the ranks.

However, while MECs are incredibly powerful, they are not invincible. They are like XCOM's equivalent of tanks, and much like tanks, they tend to draw the biggest amount of enemy fire in the map (This is especially made more problematic by the fact that even the aliens' basic plasma pistol can be a threat to MECs and the enemy AI will usually prioritize anyone not in cover.), very limited ammunition stores that forces frequent reloads, and overall tend to lose against numbers where they're simply drowned by the sheer amount of attacks that come their way. Thus, relying completely on MECs isn't the best strategy, it is always best to supplement MECs with some infantry troops for support.

Warmachine

Warmachine has had a number of different armors that technically qualify as power armor (almost all warcaster armor, for instance, includes enhancements to the wearer's strength and speed fueled by their magic), but probably the closest (and likely most famous) thing it has to traditional power armor is Khador's Man-O-War armor. Designed because Khador found it the lack of materials to make cortexes for its Warjacks meant even with the effort it put into building its jacks to last, it had a problem with still having a lot of resources it wasn't using and its lack of any cheaper jacks meant the jacks it had tended to be too badly outnumbered. To compensate for these problems, they designed huge suits of armor that would allow the wearers to function almost like pseudo-Warjacks. The Man-O-War functions the same way Khador's jacks do: it's slow, heavily armored, and hits really hard when it gets in close. Fluff wise there's a problem with the built in boilers releasing steam where it shouldn't go and killing the wearer, but this doesn't show up in gameplay since it would make them too unreliable (plus it only happens when they're damaged enough, depending on the addition to the game). Not that they care as they gladly DIE IN STEAM!! Since the armor is still expensive to manufacture, Khador only allows its veteran troops to wear it, meaning they possess high skill with melee weapons.

While the Man-O-War is an industrialized solution to lacking mechanical brains for light warjack-production, they are not the only power armours in the Iron Kingdoms: Some very exentric mechaniks actually build their won armour called "Ironhead armour". Though the Man-O-War-armour is big and scary, these tend to be even larger and impractical, and are usually build so only the bearer can use it properly. The use for these is everything from mechaniks-work to warfare, as proved by Captain Dominic Darius of Cygnar, who actually build himself a small, wearable light 'jack which in turn creates new miniature 'jacks called Halfjacks as long as he activates the thing. The thing is a four-ton heavy machine, that births smaller machines at all times. I couldn't make this shit up.

Also, the Iron Kingdoms RPG allows players to own these armours - The Gods, Nations and Kings expansion allows for the use of Man-O-War armour and career, and the 52# issue of No Quarter has rules for your own custom-build murdermachine of steel and awesome.

Star Wars

The Star Wars Expanded Universe has had some minor power armor use. The iconic stormtrooper armor is unpowered, but the "zero-G assault stormtrooper" or "spacetrooper" armor is a set of powered armor that is worn over stormtrooper armor and may have been associated with the dark trooper armor with was bigger and several dozen times more strength enhancing and protective but so unlucky it attracted the most deadly of jedi forces in mere seconds and was canceled for that reason. It incorporates a set of thrusters and other integrated weapons. Visually, it looks a bit like a cross of Terminator armor and NASA's Manned Maneuvering Unit, with a goofy, oversized stormtrooper helmet.

These were all based off mandalorian armor which was more streamlined and effective than storm trooper armor but also more expensive.

Power armor isn't used as much due to how useless armor is in the universe compare to plot armor.

There's also the Phase III Dark Troopers, which functioned as both automated robot infantry or could be worn as Power Armor, and was pretty much 40K Terminator Armor that wasn't hunched over, and had a built-in jetpack along with fun stuff like micromissiles.

Sadly, like all cool things in the Star Wars universe, it shows up for just a couple games and books, then gets immediately destroyed and you never use it.

Real Life

While they are still some ways off from producing a fully functional power suit, there is interest in the idea. Some people are now looking into making functional powered exoskeletons, this includes some guys in Japan and the US government. The basic idea works well enough, but there are still in the experimental phases and while they got the basics of the "power" part down they have yet to add the armor.

Even so, they still have a fair bit to go since the batteries for these things have at most a few hours of juice. Still, the first airplane's flight only was about 35 meters.

They're the only Superpower ability that aren't fictional(or at least Considered Pseudoscience IRL)
