Due to the size of this page, we've had to split off the biggest three factions into their own subpages:
open/close all folders
InfestedA nonpolitical faction that has spawned out of a synthetic disease called the Technocyte Plague, that turns its victims into deformed monstrosities.The Infested spawn in much greater numbers than other factions, and swarm their enemies with powerful Chargers that can take out a Warframe lower level than them in a few strikes, and Runners that explode in proximity to enemies to stagger them. There are also Giant Mooks called Ancients, that are much slower than regular Infested, but can absorb much more damage and drain energy, health, or heal their allies.
- Action Bomb: Runners. They charge at you, then explode. Or they explode if you kill them with gunfire. But not if you slice them in half with a flaming sword or punch them to death. Depending on the level you're playing in, melee may be tricky, as they'll either be unaffected by the knockback, or explode faster than you can swing.
- Body Horror: Hammered home by their encyclopedia entry showing a Corpus crewman who has been painfully transformed.
- If you look very closely at Chargers, you will see that they still have vestigial Grineer heads fused into their undersides, turned all the way around to face the front. Those colored shells on their arms and back? Ferrite armor. And where the back of a Grineer's neck would be? A skeletal, almost-canine face.
- Call Back: The Technocyte virus was the source for the zombie like enemies in darkSector.
- Evil Laugh: The 'runner' family of enemies let loose a rather nasty sounding chuckle now and then.
- Hive Mind: Heavily implied, since they show degrees of coordination on the greater scale, despite individual members being animalistic.
- Human Weapon: Their intended purpose, Gone Horribly Right. The Orokin developed the unique underlying technology to help them fight the Sentients; clearly something went right - but then the Orokin were seemingly betrayed by the Tenno. Since then, the Infestation has run rampant across the solar system.
- It would appear that they are once again in Update 14, this time under the guidance of a very much alive Alad V.
- Ninja Pirate Zombie Robot: As of Update 14, and especially Update 15.5, we have a zombie plague that can zombify robots.
- Organic Technology: With heavy emphasis on the 'organic' side, but it's surely not called the Technocyte Virus for giggles either. Presumably the heavy emphasis on the organic side was to foil the Sentients, who seemed to be able to turn the Orokin's 'conventional' high-tech weapons against them with terrifying ease.
- Taken Up to Eleven with Alad V's experiments, which appear to involve letting Virus-ridden stalks harvested from the Orokin Derelicts infest Corpus robotics as well as crewmen.
- Sealed Evil in a Can: The Infested originally hadn't been seen since the Sentient War... until Dr. Tengus dug them up and let them escape into the system.
- Shoot the Medic First: The Ancient Healer is Exactly What It Says on the Tin and deserves the same treatment as other Medics.
- Taking You with Me: The Noxious Crawler releases a poison cloud on death, and the Runner is a straight-up suicide unit.
- Technically Living Zombie: Since they technically never died, and otherwise act like a highly-mutated and aggressive animal.
- Took a Level in Badass: As of Update 10, Crawler-type Infested move much faster.
- The Virus: The Technocyte virus, of course. Infestation also appears to be lifeform of some kind in its own right, as viny growths and blooms appear on floors and walls where they Infestation is present. Orokin derelict vessels, where the Technocyte has had plenty of time to fester, are overgrown with huge, rootlike tendrils.
- Was Once a Man: All of them.
- With the Infested Moa and Ospreys and revamped J3-Golem, dilute that down to "most of them".
- We Can Rule Together: Following a plot thread from darkSector, they consider the Tenno to be their own flesh and want them to join the Infested.
- Zerg Rush: On its own, any Infested enemy is little threat. A swarm of Chargers, exploding Runners, persistent-poison-cloud Noxious Crawlers, energy and shield-draining Ancient Disruptors, and shield-piercing Toxic Ancients, however - and they always attack in numbers - can stunlock a Tenno to death before you can get a counterattack or ability off.
LephantisIntroduced in Update 10, this is the boss of the Orokin Derelicts. Drops parts for Nekros.
- Attack of the 50-Foot Whatever: Lephantis is gigantic, the biggest creature you have to fight in the game by a mile. Seriously, not even the Jackal even comes close to its titanic size.
- Flunky Boss: In both battle phases, Lephantis can create pods, from which regular infested units come out.
- Poisonous Person: Even moreso than J3.
- Shockwave Stomp
- Sinister Scythe
"(We are the vessel through which immortality is achieved. Assimilate, <player name>.)"The former boss of Eris, now appearing whenever there is an Infestation outbreak in place of the system's usual boss. A gigantic red Infested Charger with several deadly psychic powers. Drops blueprints for Nyx.
- King Mook: It's a charger except really big and red.
Mutalist Alad V
"Inhabitants of the Origin System! It is my singular pleasure to announce that today is the first day of a new empire. An empire populated not by Corpus, not by Grineer and certainly not by the Tenno. No, the Mutalist Empire will be populated by you. A glorious new you, baptised by Mutalist flesh. You’ve called this a disease, an infestation? I call it Unity. One army under me. Welcome to your new species."On the run from the Corpus for bringing General Sargas Ruk's forces upon them, and the Tenno for his Project Zanuka experiments on their fellow members, the mad scientist Alad V has decided to a different force for power, the Infested, and working on Mutalist technology. Now filled with further delusions of grandeur inspired by the corruption of the Infested hive mind, Alad V cares not for any lines crossed in his pursuit of ruling the stars. Tenno will have to complete the "Patient Zero" quest to find, and fight him, to put an end to his mad desires.
- Mercy Kill: Lotus remarks to the Tenno that not only will Alad's assassination put an end to his plans, it will also be granting him the mercy of freedom from Infested control.
- Sanity Slippage: When the appropriate response in a never ending warfare between Space Ninjas, Conquering Empire, and Greedy Business Mega-Corp suddenly encounters Infested is to stop fighting each other and begin pointing weapons at the Infested, and he decided that infecting, and joining up with them was the best response? Yea no slippage here, more like a leap off a cliff into a really dark void.
- Hoist By Your Petard: He can catches you with his infested collar and take control of your Warframe. If you are using something like 4 Forma Amprex...
The Syndicates are organizations that don't have quite as much power as the three big players, but they still make their mark. A complex system of alliances, rivalries, and conflicting ideals prevent them from truly unifying but they do have two things in common: a hatred of the dominant powers of the Origin System and alliances with the Tenno.
- This war's chewin' up the weak and innocent. No one stands up for them but Steel Meridian.
- Dangerous Deserter: An inversion, as they deserted the Grineer Empire in order to protect those being hurt by the constant warfare in the Origin System.
- Defrosting Ice Queen: Their leader starts off with a pretty negative attitude towards Tenno, but as they climb the ranks of her organisation, she'll warm to them considerably, eventually admitting that she was wrong, and that they are heroes.
- My Species Doth Protest Too Much: The leader of Steel Meridian is a female Grineer deserter; she's coarse, direct, and devoted to protecting those who can't protect themselves.
- Shotguns Are Just Better: Two of their three unique weapon mods are for Grineer shotguns: the Hek and the Sobek.
- War Is Hell: But so long as they can help divert the battles away from innocents, then they'll take it as a victory.
Arbiters of Hexis
- The Arbiters of Hexis seek truth through trial and discipline. The Tenno will surpass their former masters.
- Nice Hat: Their helmets are... impressive.
- Mythology Upgrade: What they want the Tenno to go through. The whole "Rejecting Tenno's Warriors ways" doesn't mean that they reject the Tennos' skill as badass space ninja commando warriors. They just happen to reject the idea, and story that the Tenno are *only* that, suspecting there is a much higher calling for them that's been lost to history.
- You are curious. So am I. Cephalon Suda could help you unfold this strange map of existence.
- Benevolent A.I.: She has zero interest in violence, just observing the world and gathering knowledge.
The Perrin Sequence
- The Perrin Sequence reject the Corpus doctrine that conflict is opportunity. We see the numbers differently. A shared prosperity can bring a shared peace.
- Defector from Decadence: They take great issue with the regular Corpus over their war profiteering ways, and instead want to bring prosperity back to all through more peaceful trades.
- Honest Corporate Executive: Straight up honest with the Tenno, as well as pointedly focused on gaining profit through peace instead of conflict.
- My Species Doth Protest Too Much: These guys are pretty much the Corpus answer to Steel Meridian, having the view that the regular Corpus have it wrong.
- Not So Different: Like Steel Meridian, they want to help the innocent, with only their preferred methods being different (Preferring to do honest business, compared to being La Résistance), that one has to wonder why they don't help each other, and are instead direct enemies. Perhaps old Grineer versus Corpus hatreds die hard?
- The old ways speak of a cleansing fire. We of the Red Veil must burn away this corruption to begin anew.
- Badass Normal: No crazy superpowers, no Precursor weapons. Far weaker physically, and far less trained. They are still fighting.
- Escort Mission: Prior to Update 15, they only show up in these. Not as annoying as most escorts, because you can give them your pistols, and they have aimbot-level accuracy with them. It's worth mentioning that you can give them any pistol, from the lowly Lato to the Brakk shotgun revolver. They will also hit a semi-auto weapon's maximum fire rate with ease. Even the Lato can shred enemies when fired at speeds human fingers could only dream of. They also have no issues using weapons with unique firing mechanics, like the manually triggered Castana electric traps. They also don't need to worry about ammo consumption, and can take full advantage of a pair of Viper or Furis machine pistols.
- Kill 'em All: Their method of purging corruption from the system is to target everything nearly indiscriminately. All corruption within the system has to be wiped clean, no matter the cost.
- La Résistance: The first faction of normal humans seen, resisting both Grineer and Corpus. If anyone is even suspected of belonging to the Red Veil, they are roughed-up and their ship is seized. Considering their ideology is built around massive violence against the evils plaguing the world....
- The Unfettered: They will apparently go to any length necessary to destroy the corruption they see everywhere, no matter what it costs them. Considering that the wiki says that two of their favorite weapons are the Embolist and Mire, both Infested weapons, (!) that should be worrying.
- According to the devs, though, they do not attack civilian targets and try to avoid harming those they call 'innocent,' explaining their alliance with Steel Meridian. They just focus on the destruction of the corrupt rather than protection of the innocent. The Veil is the sword, and the Meridian is the shield.
- New Loka believes true humanity is the only way to cleanse ourself of this suffering.
- No Transhumanism Allowed: Their entire ideology is built around going back to a pure human form, to the point that they are flat-out enemies with Cephalon Suda.
- The Unfettered: Like the Red Veil, they have no qualms about how far they have to go to reach their objective, to the point that they're willing to use Ancient Infested as both specters and retaliation squads.
- A warrior only grows if they face the ultimate enemy. Themselves.
- Nice Hat: Teshin has an impressively large bowl-shaped hat◊ that covers his eyes (apparently a running theme with the Orokin).
- Is this murder? No. All beings of substance die eventually. Only those forgotten are truly dead.
- Mission Control: If there's a Sanctuary Target nearby, he'll pop in to tell you about it when the Lotus is done talking. He also shares screentime with Lotus during the "New Strange" quest.
- Unwilling Roboticisation: Sanctuary Targets appear to get disintegrated, analyzed, and rebuilt in the Sanctuary as digital lifeforms. Of course, the Tenno would probably end up killing them either way.
- Virtual Training Simulation: Gain enough standing with Simaris, and he will allow you into the Simulacrum, where you can face virtual copies of enemies you've scanned with your Codex.
The Orokin EmpireThe only living remnants of them seem to be the Guardians of the Orokin Void, Corrupted are Grineer and Corpus troops, with the occasional Infested Ancient, who have fallen to the tower's defenses and been remade into a loyal servant force.
- Abusive Precursors: We've seen little of them so far, but the Codex entries for Ember Prime and Rhino Prime hint that they experimented on children from a vessel lost in the void to create the Tenno.
- Godzilla Threshold: Creating you.
- Hoist By Their Own Petard: If it wasn't the Tenno who killed them all, then the Technocyte Virus sure didn't help.
- Light Is Not Good: The Orokin color-scheme is bright white and gold.
- Mind-Control Device: The Corrupted have a visible Orokin crest on their heads, which is how they're kept controlled, and possibly as a means of communication.
- Psycho Rangers: The Corrupted are this to Corpus, Grineer, and even the Infested. They are essentially intruders mind-controlled by Orokin defenses.
- Redshirt Army: The Zero-Techs, who wielded percussion rifles, in a universe full of far more advanced tech. Every time a Sentient Worm-Ship blasted an Orokin Splinter Ship, it was nearly guaranteed that all Zero-Techs aboard would die instantly. In fairness, given how badly the Sentients were subvertion Orokin technology and advances, going low tech was the only option the Orokin had.
- Avenging the Villain: The Stalker's reason for wanting to kill the player is the player having killed a boss. That all of them are assholes does not give him a moment's pause. Players tend to first meet him at the time they reach a high enough rank and power level to farm said bosses. He's meant to give players pause in between them mindlessly stomping the likes of Vor for blueprints and materials.
- Curb-Stomp Battle: The Stalker tends to be quite high level, so if he ambushes you when you're in a lower-level frame with weaker weapons... it's not pretty. To make it worse, the Stalker only shows up after you kill a boss, but never in boss missions. Suppose you just did one repeatedly to get the parts for a new Warframe, made it, and are now taking your fresh, level zero, toy for a spin. On the other hand, this can be turned 180° when he tries to attack a team of four high-level Warframes. Even at level 70, he can go down rather quickly, making his mysterious appearance and quick disappearance more of a joke. Due to a few bugs that occurred with update 11 the Stalker can now one hit kill a full tank-built Rhino (the tankiest of the Tennos) while being invincible if it uses Nyx's Absorb ability - making a scenario where the Stalker kills most if not the entire team in seconds while hardly taking any damage entirely plausible.
- Enemy Civil War: The Stalker is flagged as enemy for any faction you are currently fighting against. Appearing in a crowd of enemies causes them to attack him as much as the player. This can be done to your advantage if you have a Shade with Ghost. Allowing you to sit back and watch him being worn down by your enemies.
- Even Evil Has Standards: Though he avenges corporate tools and expansionist xenophobic fascists, he draws the line at Captain Vor, the first boss you have to fight, because that would just be unfair to the player. In the past he would also ignore the death of Alad V, who dissects Tenno for twisted experiments.
- Evil Counterpart: Resembles, and acts like a Tenno; he appears to be wearing a black and red Excalibur-class Warframe with a unique helmet. He also has dark versions of Slash Dash, Teleport, Pull and Absorb.
- Flash Step: Has Ash's ability to Teleport and Excalibur's ability to Slash Dash.
- As of Update 11, he's more likely to Teleport Spam into a melee combo.
- Hoist by His Own Petard: He attacks Tennos with modified versions of their weapons. However, when he's killed, he drops blueprints for his own gear, and thus can be killed him with his own weapons in the next encounter.
- It's Quiet... Too Quiet: Whether Stalker will attack you is decided in the first 4 minutes of a mission, including right at the very beginning. In the latter case, the level won't have any enemies in it, only eerie silence as the game waits for a good moment to taunt you.
- Knife Nut: Despair, his throwing knives, have a mono-filament edge specifically designed to penetrate Warframes.
- Mage Killer: He can shrug off Tenno-inflicted debuffs, Dispel their defenses, effortlessly dodge or even Absorb their attacks, and somehow manages to track them entirely on his own. His weapons are even noted to be specifically crafted for killing Tenno.
- Mini-Boss: The first of it's kind in Warframe. Much more powerful than most regular enemies, and appears randomly during the mission instead of being an Assassination Target like regular bosses.
- Mirror Match: Against any sufficiently competent stealth-based player. Expect to sneak around the map taking pot-shots at each other for a while before any actual confrontation ensues.
- Nightmare Fuel Station Attendant: To those not expecting him. You're a new player casually starting another mission, feeling good after your latest boss kill, when the lights start flickering. You shrug it off as a momentary graphics failure, until a face you've never seen appears on-screen and you get the message, "You can't run from your past." A minute later, you've been killed by an enemy you never got a good glimpse at. After that, the non-stop flickering on Infested ships just becomes constant Paranoia Fuel.
- Even for players expecting him, on rare occasions. Think the flickering is bad? Try having the screen flicker, then turn red, with the silhouette of the Stalker running past you during that red flash.
- Nonstandard Game Over: Normally, being defeated by an enemy will knock the player to the ground, causing them to bleed out and allowing them to continue attacking with their sidearm and reduced mobility, while giving their allies a short window to rescue them before death sets in; being defeated by the Stalker, even in a full party, will instantly kill the player.
- No Sell:
- If you try to use a debuffing/crowd control power on Stalker, he ignores it. He will however take all of any damage the ability deals at the same time.
- If a power only deals damage, like Slash Dash, he'll ignore all of it.
- Initially, Stalker was to not be able to attack cloaked Tenno. After Update 10 this has now been changed. He can nullify invisibility and other buffs like Iron Skin, and his ability to nullify these also stuns the target, allowing him to get free hits in. No longer can he be cheesed with invincibility or invisibility.
- Power Nullifier: He recently gained the ability to Dispel the beneficial effects of player Warframes with a puff of smoke.
- Really 700 Years Old: According to the Stalker's entry in the Codex once you get 3 scans, he was there when the Orokin fell.
- Red and Black and Evil All Over: His color scheme, essentially.
- Red Eyes, Take Warning: His portrait/helmet has red markings on the visor.
- Sinister Scythe: Hate, his weapon of choice, is a modified kama. Exceptionally dangerous in that it staggers you on hit, allowing the Stalker to perform highly damaging combos on you.
- The Computer Is a Cheating Bastard: The Stalker is programmed to register abilities being activated and will downright spam his dispel ability to deactivate them, ignoring players being invisible therefor not supposed to be registered by him. He has unlimited energy being able to endlessly chain his abilities. He can switch between primary and secondary weapon without being hindered by a switch animation (being able to fire his bow and throw throwing knives at virtualy the same time).
- He is also extremely accurate, with constant evasion being the only way to avoid being killed immediately. The only reason he might miss is because he tends not to lead targets. That being said, stop moving for even a second and he will kill you.
- He currently registers damage oddly. Normally an advanced player will have a high enough damage output that in a fight between them and the Stalker, who wins depends on who gets the other in his sights first. Sometimes however, the Stalker will effortlessly shrug off huge amounts of damage for no apparent reason.
- The Straight and Arrow Path: Dread, his bow, fires axe-headed arrows capable of dismembering enemies.
- Voice of the Legion: Has an interesting echo effect to his voice, and it causes the lights to flicker.
- Weaksauce Weakness: Before one of the updates, he had difficulty attacking Tenno who were standing on crates.
- You Will Not Evade Me: Not only can he Pull Tenno off the high ground, he can also teleport them to him if they leave the room he spawned into.
The SentientsThey were the opponents of the Orokin Empire during the war. They had undulating Worm Ships with fearsome firepower, and could subvert any Orokin technology. According to Excalibur's Codex entry, the Warframes were designed to fight the Sentients.
- Disintegrator Ray: Their preferred weapon. The original Mirage was lost to one.
- Godzilla Threshold: The Old War was responsible for introducing the Tenno and Infestation to the Orokin System.
- He's Back: Centuries after their defeat, they return to the solar system in Tombs of the Sentient. This is probably a bad thing.
- The Unseen: Until Update 16, the only way you'd even know about the Sentients is from Codex entries and Lotus dialogue.
Baro Ki'TeerAlso known as the "Void Trader," Baro Ki'Teer is a merchant who periodically appears in the various Tenno-controlled Relays around the Origin System, trading in the various Prime components that can be looted from the Void and Orokin Derelicts. He offers extremely rare items from the Void that can't be found anywhere else, assuming Tenno are willing to pay his prices.
- Adventurer Archaeologist: By trade, he pretty much loots ancient ruins and trades in ancient Orokin treasures. He'll also tell you in the trading tutorial that part of why he's dealing in Void items is because of the thrill of adventure when exploring them.
- Conspicuous Consumption: He more or less pays the Tenno, the most dangerous warriors in the Origin System, a quite valuable set of items, in order for them to go out and battle hordes of Corpus and Grineer in order to mine a rare and special cooling mineral called Cryotic, all to keep a special delicacy of squid properly cooled for transport off-planet. Yes, he quite literally paid the Tenno to deliver him refrigerators.
- Fiction 500: He is stupidly rich, to the point that, according to Darvo, one needs to spend entire crates of Prime blueprints and argon crystals just to get invitations to his parties.
- Finger Tenting: His favoured pose, fingers tip-to-tip rather than interlaced.
- Global Currency Exception: He only accepts Orokin Ducats, which he gives in exchange for Prime parts and blueprints. Given that most of his items are worth hundreds of ducats, and he offers at most fifty ducats for the best Prime components... you'll be selling him a lot of parts.
- Mysterious Backer: He's the man behind the Cryotic Front event, who kept his real identity hidden because he likes being mysterious. At least until Darvo outed him in annoyance because of a longstanding personal grudge and rivalry.
- Nice Hat: His hat is pretty fabulous, nobody can deny that. Though one does have to wonder how he can see anything.
