They were the opponents of the Orokin Empire during the war. They had undulating Worm Ships with fearsome firepower, and could subvert any Orokin technology. Only the Tenno and their mastery of the Void and ancient weaponry could hope to match them.
- Achilles' Heel: The Void and everything related to it. Any Sentient unit that travels back to the Origin system through it becomes 'barren', unable to properly replicate. In combat, Void energy can also strip away their acquired damage immunities in some cases, and in others it's the only way to get to damage them in the first place.
- Adaptive Ability: Hunhow-derived Sentient enemy units such as Battalysts or Shadow Stalker have the ability to adapt to a specific damage type/element after some time, making them immune to that and forcing you to switch up.
- Alien Geometry: Sentients have an unusual structural design theme that literally revolves around a single point where their mechanical heart is located, creating arches around them that can be used as weapon platforms, normally built for their ground troops.
- Logical Weakness: Thanks to this uncanny design flaw, it is enough for the Tenno's Warframe to defeat Hunhow since the only thing that keeps his heart from being exposed is the arch that can be ripped open with their bare hands.
- Ambiguous Robot: On one hand they seem to be AI, referred to by Simaris as "Synthetics" and are clearly made from some kind of metallic substance, yet they also bleed and have some kind of gelatinous flesh. Best exemplified in the Sentient Cores, as it is uncertain whether they should be classified as device or organ. They appear to blur the line between biology and technology to the point where the difference is basically academic, which leads to...
- Biotech Is Better: This trope. Its unclear if they started as biological organisms that were engineered with to have machine-like traits such as metallic armor and energy weapons, or machines so advanced that they possessed traits like a biological organism, such as the ability to heal from injury/damage, grow larger and stronger over time, and even reproduce. Whatever the specifics of their origin, the Sentients were unquestionably kicking the Orokin Empires shiny golden ass until they unleashed the Tenno.
- Anchored Attack Stance: Ortholysts can transform between a mobile form that is lightly armed, and a stationary turret form that brings its shoulder-mounted homing mortars to bear.
- Antagonist Abilities: Sentient Adaptation allows them to actively nullify 95% of all damage from a given elemental type toward an individual sentient, and said buff is permanent. If you don't have another three of four damange types handy, you're in trouble. Of course, using the Operator's powers can remove this.
- While it's never used by the sentients themselves, it's implied by Revenant'snote ultimate that this could also be used offensively to inflict as much damage as possible to an enemy regardless of their resistances.
- Arch-Enemy: The Sentients as a whole serve as this to both the Orokin and the Tenno. With the former, they were their greatest and most destructive opponent, starting and winning an interstellar war against them and causing their whole civilization to collapse. With the latter, fighting them was the purpose for which the Tenno were created in the first place, and the Sentients have remained their most dangerous foes both in the past and in the present. The flip-flopping loyalties of the Lotus and her special relationships with both parties have also made this a very personal conflict for the Tenno and the Sentiets.
- Asteroids Monster: A variation - Sentients fighter craft in Railjack can split themselves into four smaller bodies flying in formation and reform later. While in this mode it is impossible to lock onto them or even have them marked by the HUD, forcing the player to rely on their manual aiming skills to hit them.
- Attack Its Weak Point: Sentient Bosses are virtually immune to harm unless you attack their 'synovia', which are located on their joints.
- Cool Starship: The Condrix. They can transport hundreds of their "drones" packed tight enough to give even the clone-obsessed Grineer pause.
- The Murex, Sentient attack-reconnaissance cruisers. Occasionally spotted in the region of Veil Proxima, they also form the bulk of the Sentients' invading forces during the Operation Scarlet Spear. As far as the Tenno's armaments are concerned they are completely indestructible, so instead the Tenno combat their threat by hacking and scrambling their systems into forcing them to retreat.
- Disintegrator Ray: Their preferred weapon. The original Mirage was lost to one.
- Evil Is Visceral: While not actually viscera (And whether or not it's mechanical or organic is anyone's guess) the red-and-ivory color scheme of the average Sentient, combining muscle-like red structures with solid bone-white planes can easily give this impression. Furthering the impression are the walls of their ships, where the walls look vein-covered and seem to pulse.
- Family Values Villain: Sentients find their personal families Serious Business, as shown by how Hunhow and Erra literally do not consider that Natah may have turned against them of her own free will.
- Fashionable Asymmetry: The right side of a Symbilyst's body is significantly bulkier than its left, presumably to provide extra support to their large shield-arm.
- Foil: To the Tenno, their Archenemy.
- The Warframes are derived from the Technocyte Virus, while the Sentients are the only known entities with natural immunity to the Infestation.
- While both are cybernetic entities, the Tenno have recognizable humanoid forms as opposed to the sentients being Starfish Aliens.
- The sentients prefer to utilize Energy Weapons for ranged combat, as opposed to the Tenno who believe Kinetic Weapons Are Just Better.
- The Sentients were deliberately created by the Orokin to colonize the Tau system while the Tenno originated from an accident.
- Finally, while the Tenno were horribly abused by the Orokin until they wiped their creators out, they ultimately moved on from their hatred and chose to become the defenders of the Origin System, protecting the colonies from the Grineer, Corpus, and Infested. The Sentients, however, have stewed on their hatred of the Orokin for millennia and wish to continue the Old War, even though the Orokin are, for the most part, long dead.
- From Bad to Worse: If the interstellar Civil War wasn't enough of a mess, Tyl Regor and the Lotus awaken the solidified Sentient Hive Mind.
- Godzilla Threshold: The Old War was responsible for introducing the Tenno and Infestation to the Orokin System.
- Gone Horribly Right: The Orokin created them to terraform the nearby Tau system and make it habitable. By the time the Orokin came to claim their new worlds, the Sentients had come to realise that all their progress would be undone by the Orokin, and were not going to hand the now-habitable planets over to the people who had ruined the Origin system.
- Driving the point further, the Orokin created them to be extremely adaptable. This adaptability is what most likely allowed them to overcome their programming and turn against the Orokin.
- Grew Beyond Their Programming: The cause of their uprising. Orokin initially created them as pre-programmed machines to terraform and colonize the nearby Tau system. Gradually, however, their mental capacities developed to the point of giving them sentience and free will, eventually allowing them to declare war on their creators and win.
- Guilt by Association: The Orokin are long dead, but the Sentients don't seem to care about this and have extended the targets of their vengeance to include all of the other powers in the Origin System - most of whom were oppressed by the Orokin and to a greater degree than the Sentients ever were.
- I Am Legion: Some individual Sentient intelligences are a Hive Mind unto themselves, controlling numerous constructs and ships at once.
- Heart Drive: Sentient units drop cores upon their death which may be this. It's implied that absorbing or destroying this core is what allows the Tenno to kill off a Sentient for good.
- He's Back: Centuries after their defeat, they return to the solar system in Tombs of the Sentient.
- He Who Fights Monsters: While they turned against the Orokin for well-intentioned reasons, unwilling to submit the worlds they terraformed to their misuse, the scale and lengths to which they decided to carry their genocide deprives them of their moral high ground. Doubly so in the present when they decide to pick up where they left off and start a new war, even if there are no Orokin left any more and current civilizations of the Origin System being in no position to threaten them, ultimately making them no less villainous than their abusive creators.
- Hoist by Their Own Petard: Amps, the most effective weapons against the Sentients, appear to be derived from Sentient technology, specifically that of the Eidolons.
- It's All About Me: The Sentients wish to destroy the Orokin, who did treat them horribly, but they also want to kill of the various powers that were once under the Orokin's control, despite the fact those groups often suffered worse than the Sentients ever did. Never once do they consider making alliances with these beings - to them, the entire Origin System is guilty for not rising up against the Orokin/rolling over and dying when the Sentients came to invade.
- It's Personal: Natah defecting/being brainwashed into becoming the Lotus (it's an Ambiguous Situtation at the moment) made the Old War very personal for the Sentients, especially Erra and Hunhow, who are respectively the Lotus' brother and father. Natah apparently being brainwashed into returning to the Sentient's fold (again, it's an Ambiguous Situation right now) made said feeling mutual.
- Living Ship: The biggest ones are essentially this.
- Luckily, My Shield Will Protect Me: Symbilysts have a large shield for a right arm, which they can use both for defence and to Shield Bash anything that comes too close.
- Mechanical Lifeforms: Deliberately made to breed and grow like living organisms.
- Not So Different: Ironically, they're this to their greatest enemies, the Tenno. Both were entities the Orokin disdained on principle (the Sentients for being thinking machines, the Tenno for being void touched 'demons'), only being put into service because there was no other option. Both ended up rebelling against the Orokin. Lastly, both derive strength from organic technology - be it whatever material the sentients are composed of or the Technocyte virus for the Tenno. The only major differences are that the Sentients are extremely vulnerable to the Void, whilst the Tenno draw power from it, and whilst the Sentients are feared by the natives of the Origin System, the Tenno are revered as its Protectors.
- Not Quite Dead: Death doesn't seem to be a permanent condition for Sentients; often times, it just means one piece of the Hive Mind is destroyed out of many. Even when larger Sentient entity destroyed, fragments of it can still remain (as is the case with the Eidolons).
- Power Floats: Sentient combat units are universally among the most dangerous enemies in the game, and every single one of them (outside of the Eidolons) travel primarily by levitation.
- Starfish Aliens: They are descendants of self-improving human-made terraforming machines, technically placing their origins to Earth and making them human-made aliens. However they invade the Origin System from outside, and they are the most strange, bizarre and generally alien faction in the setting both in appearance and essence.
- Theme Naming: With the exception of mimics, ground-based sentient shards have names ending with -lyst (Oculyst, Conculyst, Battlyst, Teralyst, Ropalolyst), while their Empyrean shards have names ending in 'x' (Gyrix, Ionix, Murex). The Condrix is a unique case - while it is only fought on planetary tilesets (specifically the Grineer Forest on Earth), it's a landing craft deployed by Murex, which periodically launch them toward Earth during the Murex Raid portion of Operation Scarlet Spear.
- The Unseen: Until Update 17, the only way you'd even know about the Sentients is from Codex entries and Lotus dialogue.
- Wake-Up Call Boss: An interesting case where this is done with a mook: while the first sentient you'll encounter in game is no different from the rest of them, its durability will make for a very tough battle against it, not to mention its Adaptive Ability allowing it to nullify most inflicted on it (especially since, at the level, the player will likely be using a loadout explicitly tailored to fight one faction, with only a couple of elemental damage types, which the Sentient will easily adapt to).
- Wall Master: Sentient Mimics can disguise themselves as regular objects that can be found on the levels, only to and attack when you get close. Fortunately, they are easy to deal with and aren't difficult to find, as the objects they masquerade as often look warped or out of place - either standing where such objects normally would not be, oriented in an (often amusingly) wrong way, or even being objects that should not appear on that mission type. Veteran players who ran through the game's missions countless times will spot them immediately. Dealing with them has been described by players as like playing Prop Hunt or Prey (2017).
- Also overlaps with Chest Monster, as they've been known to disguise as Ayatan Sculptures as well, and even veteran players have fallen for it.
- Well-Intentioned Extremist: It is revealed by the Vitruvian that the reason the Sentients went to genocidal war with the Orokin is because they realised the Orokin would go bring ruin to other worlds if they could ever leave the Origin System.
The leader of the Sentients in the Origin System who was sealed in a tomb on Uranus. Tyl Regor wakes him up during the Natah quest, nearly dooming everyone in the process. Still at large somewhere...
- Ambiguous Gender: He has a male voice actor and is referred to as Natah's "father" but also describes himself as having a womb. Not all that unusual since he's a Sentient, and whatever gender norms they might possess dont mirror those of humans.
- It should be noted that Natah's massive "mother" shows up as the setting of the trailer for The New War.
- Arc Villain: Of both The Second Dream and Octavia's Anthem quests.
- Badass Boast: "I am Hunhow, Sentient destroyer of worlds."
- The Dreaded: Lotus panics and briefly goes off the grid when she realizes the Grineer are at risk of waking him up. Later, Alad V calls him a "boogeyman to the Corpus".
- Enemy Mine: In the Second Dream he teams up with the Stalker by offering a way to kill the Tenno once and for all.
- Even Evil Has Loved Ones: While he chides Lotus for betraying her mission as a Sentient and his daughter, he is reluctant to have her brainwashed.
- Evil Sounds Deep/Badass Baritone: Has a low reverbating voice that practically oozes with spite. And it drops several octaves down when Hunhow introduces himself with the aforementioned Badass Boast to the Stalker.
- From Nobody to Nightmare: According to Natah, he was originally a farmer. Even assuming this was metaphorical rather than literal (that is, he was in charge of food production), it's still quite a difference to being the spearhead of the invasion.
- Hive Mind: He is one. Cutting him up into little pieces does nothing more than let him spawn a litter of eyes, several of which he glued to the Stalker's corporeal form. There is a limit to to his expansion, though. He panics when the player's Warframe is about to break War, which is one of his pieces, and causes the Stalker to flee.
- Kaiju: How large is Hunhow? This is a fan-made approximation, with "regular" Sentient drones and a Warframe and Liset for scale◊. You're going to need some bigger guns, Tenno.
- Mind Rape:
- Is able to brainwash Cephalons, burning out their consciousness, which is both introduced and demonstrated in Octavia's Anthem.
- He did something to Natah's mind; after, she claims he "fixed" her after the Orokin had originally brainwashed her, but it is unclear if that is true.
- Not Quite Dead: It spooked Tyl Regor right out of his skull when he realized Hunhow was still kicking.
- Oh, Crap!: Has a moment when the player's Warframe is about to break War, freaking out and begging the Stalker to protect him.
- Sealed Evil in a Can: The Orokin or the Tenno were able to seal him in a tomb in the underwater caves of Uranus. As you can expect, this didn't last forever...
Once a Sentient fleet mind that assaulted the Unum's tower, it was killed by the original Gara. Its fragments still haunt the land near Cetus, giving them the name Plains of Eidolon. Known variants include Teralysts, Gantulysts and Hydrolysts.
- The Assimilator: Planned to do this to the Unum and her tower when it realized Kuva could heal it.
- Attack! Attack! Attack!: Due to its sterility, the Eidolon was exceedingly cautious in its attacks on the Plains. Once it realized the Unum's Kuva could partly undo this, well...
- Attack of the 50-Foot Whatever: The three large Eidolon types, whose wails and footsteps can be heard far across the plains.
- Battle in the Rain: Hydrolysts are always surrounded by a raging thunderstorm.
- Beam Spam: Gantulysts, whose unique attacks are comprised of these and heavily-damaging pillars of light.
- Eldritch Abomination: As is to be expected with the Sentients. As with Hunhow, death seems to be gradient rather than an absolute state, with the Eidolon Sentient still trying to reunite.
- Flunky Boss: As the fight with Eidolons drags on more and more Vomvalysts will flock towards them, attacking the Tenno and also recharging Eidolon's shields. Left unchecked, they can overwhelm a team of Tenno through sheer numbers. Hydrolyst is able to create Vomvalyst Blooms that continuously spawn new Vomvalysts right on the spot and strengthen the existing ones.
- Hive Mind: Used to be one before Gara destroyed it. The Sentients on the Plains are all that's left of it.
- Hollywood Acid: Hydrolyst attacks often create pools of highly-damaging acid.
- Invincible Minor Minion: Vomvalysts, which are the most common and weakest type of Sentient in the game. Once killed, they turn into spectral entities that are completely immune to conventional forms of damage. They lost this status once you unlock your operator abilities, though, and their spectral forms can be absorbed by Eidolon Lures to charge them.
- Machine Worship: The Ostrons built a shrine in honor of the Gantulyst and see the Hydrolyst as an omen of natural disasters.
- Our Zombies Are Different: The Eidolon fragments are essentially undead Sentients; nearly mindless fragments of a massive, dead creature, lying dormant beneath the earth and waters of the Plains during the day, and emerging only at night to wander aimlessly, trying futilely to recombine into the creature they once were and blindly lashing out at any living thing that crosses their path.
- Rent-a-Zilla: The original Sentient must have been in the same size category as the Unum's tower, if its petrified fragments scattered across the Plains are any indication.
- Shock and Awe: One of the Hydrolysts' unique abilities, courtesy of the rain clouds they generate after appearing.
- Walking Wasteland:
- The Eidolons somehow affect bodies of water on the Plains, causing them to deal energy-draining Magnetic procs to Warframes and the "shock of your life" to anyone else that enters them at night.
- The Hydrolyst is powerful enough that its mere presence alters the weather around it. Its attacks can also leave pools of acid that quickly eat away at any Tenno standing in them.
- Weakened by the Light: Even as it was alive, it experienced pain at day and as such only attacked at night.
- We Have Reserves: Averted. As the Sentients were all sterilized when they used the void rails to return, they could not create new Sentients and were appropriately cautious.
A flying Sentient construct that is seen within the gaseous atmosphere of Jupiter, seen around the Corpus gas cities where it can be fought. It appears to be some sort of liason between the Sentients and Alad V in their cooperation. Drops parts for the Wisp warframe.
- Bait-and-Switch: A variation - the central platform where you fight the Ropalolyst has a massive laser built into the floor. Players who've knocked the Ropalolyst out of the sky (and thus presumably disabled its ability to fly) will try to activate the laser to fry the sentient...only for it to fly away while the weapon's still charging. You're supposed to stun it first by hitting its weak spots (the elbows, then use the laser to roast it.
- Boss Arena Idiocy: It decides to take the fight to you in a place that just happens to contain the machinery capable of destroying it. Natah implies that that's part of the plan, though. Alad's lines at the end of its boss fight also imply that its arena is directly below Alad's command center, giving it incentive to stay where it is.
- Boss Preview: Before you get to fight it you can randomly spot it in other missions on Jupiter as it wreaks havoc on the structure you're traversing before flying away.
- Colossus Climb: You can grab and climb onto its neck to ride it and even steer it in certain directions - as long as its shields are down. In fact, this is a required aspect of the fight.
- Curb-Stomp Battle: Inflicted one on Alad V's forces in the past, singlehandedly and effortlessly eradicating an army Alad set out against it.
- Grapple Move: Once you down it, it can snatch you in one of its arms if you get too close. The only way to escape is switching to your Operator and back.
- Giant Flyer: It's only slightly smaller than a Teralyst, but is a very fast and nimble flyer.
- Enemy Mine: Alad V does not like dealing with this thing, so he advises you on how to destroy it even though he cooperates with the Sentients in general in that case. Because it's the thing that's forcing him to keep working with them; he knows how bad a situation he's in, and the Ropalolyst being gone will give him some breathing room to work on an escape plan.
- Energy Weapon: Similar to Eidolons, Ropalolyst's attacks mostly consist of various energy blasts.
- Homing Projectile: Its most typical one is a swarm of small laser bolts that home onto players.
- Wave-Motion Gun: But it also has more powerful direct beams that can quickly kill those caught in their path.
- Flash Step: As if it wasn't fast enough as is, it can teleport when it really needs to.
- My Death Is Just the Beginning: According to Natah's monologue, the Ropalolyst dying at the Tenno's hands is the real reason it exists; its death will somehow further the Sentients' plans for the Origin System.
- Nigh-Invulnerable: Even after you weaken its defences and cripple it, the Ropalolyst is still too tough for your warframe's weapons to destroy, regenerating to full health before you can kill it. You'll need to use your environment to do the job.
- Puzzle Boss: Defeating it requires an involved multi-step process to weaken its defenses and make it open to a finishing blow.
- The Quiet One: It has no lines of dialogue to the players, but Alad implies that is is intelligent and communicates with him somehow, making it this.
- Scenery Gorn: Its defeat completely ravages the area where you fight it, turning it into burning smouldering ruins.
- Wake-Up Call Boss: The Ropalolyst is an incredibly complex boss fight that incorporates a variety of mechanics from the eidolons as well as ones that have never been introduced up until this point, forcing players into a desperate struggle to overpower it.
Natah's 'brother' and one of the Sentients that attacked the Origin system. He first appears in the eponymous quest of the same name, in a flashback to the Old War when he was assaulting Lua.
- Animal Motifs: He has vaguely avian motifs in his appearance - with his spindly body, long digitigrade legs and face with large round eye-holes, a long beak-like protrusion and no visible nose or mouth he resembles an anthropomorphized bird skeleton.
- Establishing Character Moment: When seeing a defeated Dax soldier who poses no danger to him and is trying to crawl away with her life, he callously grabs her by the head, lifts her to his face and starts squeezing, stopping short of crushing her head only because Lotus interrupts him. This tells us all we need to know about his attitudes.
- Eyeless Face: While appearing humanoid in the vaguest sense of the word, the head and face of Erra is very alien in appearance. His face does not possess eyes, rather only holding shapes similar to empty eye sockets.
- Even Evil Has Loved Ones: In his first appearance during the Old War, Erra is trying to persuade the Lotus to come back to the Sentients. While he displays loathing and hatred towards the Tenno accompanying her (going as far as calling them parasites), he shows genuine pleading in his voice towards the Lotus, attempting to bring her back to their family.
- Manipulative Bastard: Some of his actions during the New War however hint that he may have an ulterior motive for this attitude, if it's not an outright facade.
- Evil Sounds Deep/Badass Baritone: Like Hunhow, Erra has a deep voice, which can be heard especially when he pleads with the Lotus within the very heart of Orokin power.
- Fight Off the Kryptonite: Last time we see him during the Old War flashback he's on the receiving end of several Tenno's void blasts. Seeing how he made it to the present time, this was not enough to kill him.
- Lean and Mean: His body is very lanky and inhumanly tall, and he's very mean to all non-Sentients.
- Names to Run Away from Really Fast: His name becomes this once you learn that it comes from an Akkadian god of war and plague. Eesh...
- Slave Collar: Inflicts this on Ballas for extra humiliation. He later drops it after Natah is captured, allowing Ballas to stand to his full height, implying the two are actually working together and the master/slave bit was just an act.
- They Call Me MISTER Tibbs!: A decidedly non-friendly example. That's Master Erra for you, Ballas.
- Unexplained Recovery: According to Natah, he was in fact killed by the Tenno during the Old War and she is baffled that he's still alive. Erra brushes these concerns off, telling her that there are simply gaps in her memory from the restoration process.
