!!Husks
[[folder:In General]]
[[quoteright:909:https://static.tvtropes.org/pmwiki/pub/images/ultrakill_huskcompilation.png]]

The Husks are what remain of humanity, being physical manifestations of their souls in Hell. The appearance and intelligence of a Husk depends on the value of its prior life as a human; those with little-to-no reputation become mindless beasts, whereas those who were widely known become sapient humanoids of considerable power.

* BodyHorror: All of them are, to some degree, grotesque appearances of the human body. The Schism, for example, is covered with welts, scars, and necrotic flesh, while the Stalker's skin is sunburned to a charcoal color and its torso is twisted 180 degrees.
* ClapYourHandsIfYouBelieve: Husks are empowered by the willpower of their original soul and the number of living souls that still remember them. Low-willpower individuals who weren't notable become Filth, [[ArmlessBiped too weak to form a complete body]]; on the other end of the scale, the massive and powerful Corpse of King Minos was born from a soul with strong will and legions of devoted followers. Souls that are even more powerful than that don't even need a Husk to manifest physically, as seen with [[spoiler:the secret boss, Minos Prime]].
* EvilIsVisceral: The Husks are horrifically mutilated, hostile malformations of human anatomy.
* KillItWithFire: Most Husks have a unique trait of being flammable, causing them extra damage (and even making Insurrectionists extra-vulnerable); the exceptions are the Stalker and Ferryman, who are so desiccated they have nothing left to burn.
* NotUsingTheZWord: Despite being visceral undead creatures, Husks are never referred to as zombies.
* OurSoulsAreDifferent: Husks are bodies manifested by the souls of dead humans and have more power if they have stronger will and/or are remembered by other souls. They also have a very deathly appearance to them (from the green pallor of the Filth to the flayed flesh of the Stray) that brings to mind OurZombiesAreDifferent.

[[folder:Filth]]
!!!'''Rank:''' Lesser Husk
[[quoteright:155:https://static.tvtropes.org/pmwiki/pub/images/filth.png]]

The first enemy in the game is also at the bottom of Hell's food chain. Filth are physical manifestations of the least strong and notable souls of the damned, so much so that their bodies are incomplete. With no arms or facial features beyond a gaping maw, they can only rush foes down and chomp. They're easily dispatched but come in great numbers. Debuts in 0-1.

* ArmlessBiped: Filths are bipedal creatures with no arms.
* AstonishinglyAppropriateAppearance: The simplicity of the Filth's design readily communicates its role as the game's most basic enemy, helpless at doing anything except running and biting. Hakita cites this in the Developer Museum entry about the Filth, specifically when comparing its final design to its first, a fully-formed zombie [[spoiler:that would later be used as one of the Puppets' models]]:
-->"An interesting aspect of the Filth is that, in the early versions of the demo, people complained about the AI of the melee enemies being too dumb, but those complaints completely stopped after the redesign. The new version actually looks like a mindless swarming monster that only thinks about eating, so it being dumb no longer felt out of place or like a flaw. Properly messaging the purpose of an enemy or object through how it looks is an often underappreciated aspect of character design."
* AttackAttackAttack: Filths' combat "strategy" consists only of bum-rushing their target and lunging at them.
* ConvenientWeaknessPlacement: Often conspicuously positioned near lethal falls and traps as a way of showing players how to incorporate them into your combos.
* DeadlyLunge: Brutal difficulty gives these zombies the ability to jump towards V1, letting them close distances much faster and making them a more oppressive threat.
* EyelessFace: They don't have eyes either.
* TheGoomba: Killed in one shot and with only a melee attack, they shouldn't give much trouble even to novices.
* ShoutOut: They're named after an album by Music/{{Swans}}, and their face resembles the cover of said album.
* ZergRush: Seeing less than three Filths at the same time is extremely rare, and that number quickly increases as you delve deeper into Hell. The only time a Filth spawns alone is when the game introduces the concept of Idols buffing enemies and does so to teach the player.

[[folder:Stray]]
!!!'''Rank:''' Lesser Husk
[[quoteright:189:https://static.tvtropes.org/pmwiki/pub/images/ultrakill_11_1_2020_11_58_49_pm_2_4.png]]

The first ranged enemy in the game, a skinless humanoid throwing balls of Hell Energy. Debuts in 0-1.

* BodyHorror: They lack skin, so their muscles and organs are fully visible.
* CowardlyMooks: Strays only feel comfortable attacking from a distance, so they'll attempt to run away from V1 if they come too close. Unfortunately for the Strays, they don't run very quickly at all.
* HoistByHisOwnPetard: Their lack of mobility makes it very easy to parry their own projectiles back at them. Their entry at the terminals even lampshades this.
* LeanAndMean: Despite being nothing but skin and bones, Strays still pose a threat, however small it may be.

[[folder:Schism]]
!!!'''Rank:''' Greater Husk
[[quoteright:247:https://static.tvtropes.org/pmwiki/pub/images/schism_0.png]]

A freak accident of two souls attempting to manifest into a single husk. Throws out volleys of energy projectiles. Debuts in 0-3.

* ArmCannon: Schisms have a big organic gun fused with the rest of their bodies in place of their right arms.
* BodyHorror: With its head fused into its shoulder, a bit of exposed spine, and two distinctly different left arms, it stands out among the husks as particularly ghastly-looking.
* EarlyBirdCameo: Corpses of Schisms can be seen in 0-2 on a path the Swordsmachine took. Schisms themselves appear as enemies in 0-3.
* FakeUltimateMook: They're tougher than most enemies and fire a lot of projectiles, but they're largely immobile and inaccurate.
* ImperialStormtrooperMarksmanshipAcademy: As stated by their terminal entry, Schisms cannot aim precisely due to their malformed anatomy; they instead opt to release Hell Orbs in vertical and horizontal waves in the general direction of their opponents. If V1 were to stand perfectly still, only one Orb from a Schism's vertical wave would be fired directly at them. Both attacks have wide coverage, however, and they subsequently become more dangerous during the chaos of a group skirmish--when it's easier for V1 to run into them if they're focused on another target. Downplayed on Brutal difficulty, as the Orb waves become much tighter and veer towards you if you're directly in front of them.

[[folder:Soldier]]
!!!'''Rank:''' Greater Husk
[[quoteright:180:https://static.tvtropes.org/pmwiki/pub/images/pepsiman_7.png]]

A cybernetically enhanced Stray that's stronger, tougher, and more aggressive. Debuts in 2-2.

* ArmCannon: Unlike Schisms, Soldiers have fully mechanized arm guns.
* EliteMooks: Soldiers are upgraded Strays. They move around with greater agility, fire out a cone of projectiles rather than a single one, and will try to kick you away if you come too close. These qualities complement their newfound bravery, with them approaching V1 when repositioning instead of receding. As of the Wrath + Heresy update, they can also block explosion attacks when they're grounded, taking significantly reduced damage from them.
* FacelessGoons: Their faces are obscured with a blue plate.
* KungFuProofMook: As of the Act 2 update, Soldiers are capable of blocking explosions while grounded, which drastically reduces the damage they take.
* UnnecessaryCombatRoll: They gain the ability to roll around you before shooting on Brutal difficulty, making them ''much'' harder to hit and likely to catch you off-guard.

[[folder:Stalker]]
!!!'''Rank:''' Lesser Husk
[[quoteright:254:https://static.tvtropes.org/pmwiki/pub/images/stalker_5.png]]
A soul damned to forever carry boulders up the monuments of man's Greed, retrofitted with an explosive canister. Debuts in 4-2.

* ActionBomb: Its only means of attack is detonating the container it carries on its back. In a unique take on the typical video game ActionBomb enemy, Stalkers will attempt to detonate near enemies instead of the player.
* ArtificialBrilliance: Stalkers will intelligently seek out the biggest threat and cover them in sand, and multiple Stalkers will seek out different targets to avoid overlap. If no valid targets remain, they'll relentlessly chase V1 in order to explode them.
* AntiRegeneration: Enemies it covers in sand will not bleed, making it harder for V1 to heal during fights. Stalkers themselves also don't bleed, and will detonate upon death, so trying to heal from them is futile.
* BodyHorror: It's not readily apparent at first glance thanks to their robes, but their upper body is twisted one hundred and eighty degrees, on top of being horribly emaciated even among Husks.
* ColorCodedForYourConvenience: The lights on their canister change color depending on their status; green when idle, yellow when approaching an enemy or V1, and red when they're about to explode.
* GasMaskMooks: Wear an old-school gas mask.
* HellIsThatNoise: Stalkers passively emit horrible, hoarse breathing sounds that can be heard from a long distance away, and their imminent detonation is announced by a loud, distorted whistle.
* InTheHood: They wear a small cloak that covers their head and trails off of their body.
* RemovedAchillesHeel: Brutal difficulty allows them to survive detonating their canister without being blessed by an Idol. If you see one when this is the case, you'll need to kill the bastard immediately before every enemy gets sanded.
* StatusBuff: If it detonates near an enemy, they will be covered in sand, rendering them unable to bleed and thus preventing you from healing off them.
* TakingYouWithMe: They explode upon death, dousing nearby foes in sand and doing a ''lot'' of [[MaximumHPReduction Hard Damage]] to V1 should they be hit by said explosion.
* VaderBreath: Like Streetcleaners, their presence is blatantly announced with loud, hoarse wheezing.
* VillainsOutShopping: A Stalker hidden on 4-2 can be seen [[spoiler:building a sandcastle. It literally ''[[AngstNuke goes nuclear]]'' if you destroy its handiwork.]]

[[folder:Sisyphean Insurrectionist]]

!!Sisyphean Insurrectionist
!!!'''Rank:''' Supreme Husk
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/sisypheannew.png]]
Elite Husks once recruited by King Sisyphus for his failed rebellion against Heaven. Now, they endure the eternal punishment of hoisting boulders up the monuments in Greed--their mutilated bodies left with only the bare essentials for such a task. First encountered as the sub-boss of Greed, guarding the exit of 4-2.

* AnArmAndALeg: The Insurrectionists have their heads and right arms severed as punishment for rebelling against Heaven.
* AndIMustScream: His lore entry mentions that the Malicious Face he's carrying is dead, but since it can bleed, and you can only heal off of ''living'' enemies, it's possible that the Malicious Face is still alive but helplessly used as a "flail". This also applies to the Insurrectionists, having their heads and right arms severed and pulling Malicious Faces up to the pyramid with the knowledge that they're so close to freedom yet failed to achieve it. Forever.
* BloodSplatteredWarrior: It's not just for show, his terminal entry explains that soaking their feet in the blood of their enemies allows him to walk on the extremely hot gold dust "sand" that covers the Greed layer without burning to a crisp.
* BodyHorror: He lacks his head and half of his torso, ribs and internal organs fully visible. His arm is also malformed and stretches unnaturally, and his left ankle is clearly broken. If that wasn't bad enough, a closer examination of their innards reveals that their "ribs" bear a startling resemblance to giant teeth! His lore entry states that all the insurrectionists were mutilated in this way by the angels as punishment, leaving them with nothing but the bare minimum physical features to carry out their punishment.
* DegradedBoss: Shows up in Cyber Grind as a semi-regular enemy. [[spoiler:Two Insurrectionists jump in without warning during P-2.]]
* EarlyBirdCameo: Several Sisypheans are seen in 4-1, climbing the gigantic pyramid in the background. One of them jumps off to attack V1 in 4-2.
* EpicFlail: The Sisyphean Insurrectionist uses his unnaturally stretchy arm and a ([[AndIMustScream supposedly]]) dead Malicious Face as a makeshift flail.
* EasyLevelTrick: [[spoiler: You can trick him into falling into a bottomless pit at the Red Skull arena part of 4-2 and kill him instantly.]]
* GrievousHarmWithABody: The "boulder" he carries and uses to smack you with is actually a dead Malicious Face.
* HandicappedBadass: Despite each of them missing a chunk of their body and being left with a severe limp, the Insurrectionists are among the most dangerous enemies in the game. They have beefy stamina, enough so that they don't bleed much blood unless they're lit on fire first. They also have remarkable maneuverability thanks to their jumping prowess, and this is on top of how their attacks have effectively unlimited range due to their elastic arms. Those same attacks vary in speed depending on their distance from V1, as do their windows to counterattack, making them deceptively tricky for such brutish foes.
* HellIsThatNoise: Insurrectionist spawns in Cyber Grind are heralded with the [[DroneOfDread blaring horn]] that signaled the boss version's arrival in 4-2.
* HoistByHisOwnPetard: His Malicious Face throws can be parried, and more importantly, parried directly back at ''him'', getting both massive damage and a stun as he's knocked flat on his ass for a few valuable seconds.
* InASingleBound: Should V1 be too far away for the Insurrectionist's comfort, he will catch up by jumping ''truly'' immense heights, then subsequently dropping straight down in hopes of crushing them. Once he starts his descent, the creature cannot change direction. This caveat can be [[HoistByHisOwnPetard turned against the Insurrectionist]] in "God Damn the Sun," in which he can be duped into crashing through a glass floor outside the solarium, instantly killing himself.
* TheJuggernaut: His attacks have infinite range, he can plow straight through floors and ceilings to smash you, and he can jump incredibly high to catch you. There is no running from the Insurrectionist.
* KillItWithFire: As Husks, they are capable of being set alight via explosions or the Overheat mode of the Nailgun. Not only do they take bonus damage from all attacks while on fire, they bleed further while alight.
* LogicalWeakness: Whenever their boulder attacks are parried back into them, grounded Insurrectionists are guaranteed to fall over, taking a few seconds to recover and stand back up. Each of them has a single, severely broken leg, making it far easier to topple them with the literal weight of their punishment. This is why Insurrectionists respond similarly to the S.R.S. Cannon's cannonballs, which are as large and heavy as the parried boulders.
* LosingYourHead: The Insurrectionists were decapitated as punishment for their rebellion, and somehow they're still alive.
* MadeOfPlasticine: Make no mistake, Insurrectionists are ''tough'', and the hardiest Husks in the game not counting the Corpse of King Minos. But where other Husks (even Filth) often remain in one or two pieces when they die, Insurrectionists will [[LudicrousGibs messily explode into little chunks]] ''every time'' no matter what killed them.
* MightyGlacier: Slow but mobile, tough, hits like a damn truck, and never stops hunting you until he dies, the Sisyphean Insurrectionist is a powerful Husk. Hope you save up those Dual-Wield power-ups, [[spoiler:including the secret one in the red skull arena]].
* RageAgainstTheHeavens: They took part in a [[SubvertedTrope failed rebellion]] against Hell and Heaven, and were decapitated for it.
* ShockwaveStomp: A radial shockwave is produced once the insurrectionist hits the ground.
* ThereWasADoor: Don't think hiding indoors will protect you from an Insurrectionist, as they're perfectly capable of jumping straight through roofs or floors to reach V1.

[[folder:Ferryman]]

!!Ferryman
!!!'''Rank:''' Supreme Husk
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/20220423_220422.jpg]]
A veil-clad boatman who traverses the river Styx. First appears as a sub-boss in Wrath, being encountered on its ship in 5-2.

* AmbiguousSituation: The Ferrymen's terminal entry describes how they'll attempt to kill each other to commandeer their opponent's boat. With this in mind, it's ambiguous if the Ferryman met during "Waves of the Starless Sea" is the original owner of the ship he's fought on--or, more specifically, if he's the same one Gabriel personally saved, as revealed by background details in the subsequent "Ship of Fools" stage.
* AscendedDemon: Technically a Husk. However, their devotion to God even in Hell caused them to be recognized by Heaven, and thus are granted power to guide souls through Hell.
* CarryABigStick: See that oar he's holding? He's gonna beat you with it.
* DegradedBoss: Shows up in Cyber Grind as a semi-regular enemy. [[spoiler:A few Ferrymen also appear in P-2.]]
* DemBones: What little of him that can be seen under his hood is skeletal and nothing else. It's strongly implied that all the skulls V1 uses to open doors are the heads of (similarly skeletal) former Ferrymen. According to WordOfGod, Ferrymen are skeletal due to tearing their own flesh off in order to distance themselves as much as they can from their former humanity. [[invoked]]
* TheFerryman: Ferrymen in Hell escort souls to their layers corresponding to their sins in life. As their terminal entry describes, they're also extremely territorial; should two Ferrymen meet, they will fight each other to the death, with the winner claiming the loser's boat.
* {{Foil}}: To the Sisyphean Insurrectionist. They're both Supreme Husks that serve as sub-bosses in their respective layers, but that's where the similarities end.
** The Sisyphean Insurrectionist is bigger than V1, he wears nothing but a loin-cloth, and his body is highly muscled, but missing a head and arm. The Ferryman is as tall as V1, he wears golden adornments and a divine robe that covers most of his upper body, and has a skeletal, emaciated, but fully-intact appearance.
** The Sisyphean Insurrectionist is fought on small platforms in the middle of the bright, blazing dunes of Greed. The Ferryman is fought on his massive ship, which is floating in the dark, raining Ocean Styx of Wrath.
** The Sisyphean Insurrectionist is [[MightyGlacier slow yet powerful]], but he neither has magical powers nor a second phase, he fights with instinct and sheer aggression, and he wields a (supposedly) dead Malicious Face as a one-handed weapon. The Ferryman is [[LightningBruiser fast yet just as tough]], he fights with skill and intelligence, he wields an oar as a two-handed weapon, he's blessed by the Idols unless they're destroyed, and he has a second phase where he can strike V1 from afar by summoning lightning with his Heavenly magic.
** The Sisyphean Insurrectionist must be killed, but he can be slain in under 10 seconds. The Ferryman can't be killed under 10 seconds without cheats, [[spoiler:but he [[SkippableBoss can be skipped]] if you toss a coin at him.]]
** The Sisyphean Insurrectionists are defeated by Angels and punished with decapitation for rebelling against them. The Ferrymen are recognized by Heaven and blessed with holy powers due to their devotion to God.
* {{Foreshadowing}}: The Ferryman that V1 meets in Wrath bears a few details foreshadowing both Gabriel's fight in Heresy [[spoiler: and his oncoming character development]]:
** The Ferryman's careful use of his melee weapon allows him to switch between unparriable and parriable states when attacking. Gabriel uses a much more aggressive take on the very same tactic during his Heresy fight. They both can be dealt with in the exact same way: a combination of careful evasion and observation to position them wherever it is most ideal to parry them at the correct time.
** The lore surrounding the Ferryman found within "Waves of the Starless Sea" and the "Ship of Fools" establishes that Gabriel is capable of kindness and compassion, in stark contrast to how previous lore characterized him. He was the one responsible for blessing this particular Ferryman and rewarding him with his current status. The Ferryman was so grateful for Gabriel's mercy that he set up a recording of his blessings to play on loop in his ship. These details build up to [[spoiler: Gabriel's eventual turn against Heaven after Heresy, upon realizing that his superiors have been oppressing Heaven and Hell's masses with their outdated ideologies]].
--->'''Gabriel Recording:''' Be not afraid, sinner. Your devotion to God shows goodness in you. Plentiful indeed. The heart is willing, but the body must rest, lest you squander one of the Lord's creations.
* GoldAndWhiteAreDivine: His garments may be old, but they still have holy colors.
* HoistByHisOwnPetard: The Ferryman's lightning can be deflected by a coin. [[DownplayedTrope Downplayed]] in that, unlike the similar attacks of the Malicious Face and the Sentry, this does very little damage and does not qualify for a +CHARGEBACK bonus.
* HolyHalo: The Ferryman has a gold decoration mounted on his shoulders that forms a halo in a standing position. Said halo is broken by the time we meet him.
* InTheHood: His face is covered entirely in his cloak.
* {{Leitmotif}}: "He is the Light in My Darkness".
* LightIsNotGood: {{Downplayed}}. The Ferrymen are [[HeavenlyBlue blue skeletons]] wearing [[GoldAndWhiteAreDivine white robes decorated with golden adornments]], and they're deeply devoted to God, grateful for Gabriel's mercy, and [[HappilyAdopted loving towards their adopted Idols]]. That being said, they're not entirely noble, as Ferrymen will fight each other to the death to take over a ferry, and they're unwittingly serving a corrupt CouncilOfAngels that are brutal {{Knight Templar}}s. The Ferrymen guiding souls through Hell seems like a good thing, but in reality, they're bringing souls to their designated punishments.
* LightningBruiser: He's fast, he can take a ton of punishment despite being nothing but bones and robes, and he ''hits'' hard. That's not even including [[MagicKnight the holy magic he has at his disposal]].
* ShockAndAwe: Between the two phases of his fight, the Ferryman of Wrath perches himself higher up on his ship and summons lightning to strike V1 down. Each bolt is telegraphed by a beam of light highlighting where it is about to appear and the sound of the Ferryman jingling a bell on his oar. Meanwhile, the Ferrymen spawned in the Cybergrind still have access to this attack; they'll exclusively use it whenever it is impossible for them to approach V1 on foot. This can be turned against them; aside from reflecting lightning strikes with a coin, parrying a Ferryman's attacks will generate a (non-damaging to V1) lightning strike right on the Ferryman's positioning, potentially damaging everything around it. Brutal difficulty also lets them summon lightning bolts to strike you ''in the middle of their other attacks''.
* SkippableBoss: [[spoiler:Before the fight is initiated, you can make your way up to him and toss him a coin.]] This will prompt him to open the exit, skipping his fight entirely.

!!Demons
[[folder:In General]]
[[quoteright:1000:https://static.tvtropes.org/pmwiki/pub/images/ultrakill_demoncompilation.png]]

The Demons are innate creatures of Hell, usually being formed from Hell Mass condensing into an artistic stone shell. They have only slighter higher intelligence than most Husks, and often serve to protect Hell's layers from intruders and rebellious sinners alike.

* ArtImitatesArt: Demons in general tend to resemble or otherwise bear iconic pieces of artwork on them:
** The prominent brow and flat nose on Malicious Faces resemble those of [[UsefulNotes/RapaNui Easter Island moai]]. Another detail, which became more prominent when their model was updated, is their curly hair, a quality commonly exhibited by many Greek statues of Hermes.
** Cerberus are a very simplified and modified rendition of [[ThinkerPose The Thinker]].
** Hideous Masses have [[Art/SistineChapel "The Creation of Adam"]] engraved on their forearms, with God on one hand and Adam on the other.
** Idols, very deliberately, resemble the [[PietaPlagiarism Virgin Mary cradling Jesus]].
** The Leviathan's Heart, [[spoiler:comprised of the amalgamation of the countless Sullen souls absorbed by the beast,]] is [[TheScreamParody depicted in a permanent horrified Scream]], with a pair of arteries taking place of the character's hands.
** The Mannequins are a nod to the ''Art/VenusDeMilo'' while also inverting the statue's most notable trait: whereas the ''Venus De Milo'' has no arms, the Mannequins have too many arms, with their limbs formed entirely from forearms, while the joints are made by hands grabbing the other parts.
** The Minotaur's appearance evokes that of ''Art/{{Guernica}}''. Both involve twisted, uneven shapes of human mass, involve the image of a bull, and are associated with a violent context (''Guernica'' was created in response to the bombing of is titular city; the Minotaur is sealed away within the circle of Hell dedicated to violent sinners).
* EvilIsVisceral: All Demons have red flesh underneath their stone bodies, which is visible in higher level Demons like the Hideous Mass and the Leviathan, and all of them attack every non-Demon with Hell energy and extreme prejudice. The only exception is the Idols, which lack any visual visceral traits or the hostility shared by their fellow demons.
* LivingStatue: A Demon's body consists of a stone shell encasing Hell Mass or some other kind of organic material. However, some Demons only have partial shells with their vulnerable flesh exposed.
* MightyGlacier: Thanks to their stony shells, Demons are very durable and can dish out quite the punishment. However, their stony shells make them very slow in attack and movement, and a few (like the Hideous Mass and Idol) don't even move at all. Speaking of the Idol, it has no form of attack; instead, [[SupportPartyMember it focuses on buffing its allies with invincibility]]. The only exceptions so far are the Mannequins and the Minotaur, which are {{Lightning Bruiser}}s, and possibly the Leviathan, which can swim at fast speeds despite its titanic size, though it's mostly a StationaryBoss in its boss fight.
* OurDemonsAreDifferent: Demons are a far cry from the classic BigRedDevil. Instead, Demons are {{Living Statue}}s that twist stone and flesh into one being. They also [[ArtImitatesArt reference iconic artwork]], like the Cerberuses resembling [[ThinkerPose The Thinker]] when hibernating, and tend to incorporate some mild BodyHorror, like the Hideous Mass and the Leviathan having numerous human limbs and faces. Demons are not just capable of wielding Hell energy, they can also [[YinYangBomb wield Heavenly magic]], such as the Idols using it to give enemies invincibility.

[[folder:Malicious Face]]

!!Malicious Face
!!!'''Rank:''' Lesser Demon
[[quoteright:322:https://static.tvtropes.org/pmwiki/pub/images/face_824.png]]

First introduced as the first sub-boss of Overture, encountered in 0-1. They're [[ExactlyWhatItSaysOnTheTin malicious stone faces]] that alternate between volleys of Hell Energy projectiles and devastating {{Hitscan}} laser explosives. They're also the first demonic enemy.

* AchillesHeel: There are a number of factors that allow V1 to absolutely ruin a Malicious Face's day with ease. They take extra damage from point-blank shotgun blasts, slamming, and nails. There are also two tactics that can instantly kill the Face by turning either of its only two attacks against it. For its Hell Energy volleys, V1 can parry the first one, causing a chain reaction in which each projectile in a volley is shoved back into the Face, and a correctly timed charged Sharpshooter shot into the volley can cause a chain reaction that can heavily damage or outright kill it. For the explosive laser, V1 can toss a coin and trick the Face into hitting it to deflect the laser back into itself.
* ArtificialBrilliance: Malicious Faces have a unique interaction with Stalkers; namely, they'll seek them out to get sanded and lower their altitude as the Stalker is about to explode its canister.
* BigCreepyCrawlies: They may look like floating disembodied heads, but a closer look shows that they have transparent [[SpidersAreScary spider-like]] legs.
* BreathWeapon: The Malicious Faces shoot volleys of Hell energy and laser beams from their mouths.
* {{Cephalothorax}}: As their name suggests, Malicious Faces are giant stone faces (with spider legs).
* DegradedBoss: They show up as regular enemies as early as 0-4.
* FluffyTheTerrible: They have a meme-born name that ended up appearing in the game, Maurice.
* FlyingFace: {{Subverted}}. While they're disembodied heads, a closer look shows that they have transparent SpiderLimbs.
* GlowingEyesOfDoom: When the Malicious Face becomes enraged, its eyes start to glow.
* GrievousHarmWithABody: When a Malicious Face dies, its corpse will fall to the ground and create a shockwave that blows back both enemies and V1 alike. If the Face actually ''lands'' on an enemy, they'll be instantly pancaked and V1 will be [[AscendedMeme awared a "Mauriced" style bonus]].
* HoistByHisOwnPetard: It's possible to intercept a Face's explosive laser attack with a Marksman coin, deflecting the blast back at them, instantly killing it, and earning V1 a Chargeback bonus.
* KungFuProofMook: Core Eject grenades bounce directly off of their carapace, rockets ping off before going haywire in random directions, accelerated shotgun pellets plink off (and ''only'' accelerated ones) and they take no damage from explosions.
* MascotMook: The first enemy introduced by the dev and prominent in marketing, to boot.
* NoSell: They take no damage from explosions (unless you reflect their own). Core Eject grenades and rockets in particular just bounce off them harmlessly, with the rockets then wandering off randomly afterward. This gets outright comical with the Shotgun; use Projectile Acceleration, and while every ''other'' pellet will embed itself and bleed it, the ''punched'' pellet will just plink off harmlessly and explode somewhere else.
* OurDemonsAreDifferent: Giant disembodied stone heads with spider legs that also fire explosive lasers from their mouths.
* ThrowTheDogABone: Despite its tendencies to take massive damage from anything, the Malicious Face is immune to explosives.
* TurnsRed: In Violent difficulty, Malicious Faces enrage when half of their health is gone, making them fire Hell orbs more frequently, or fire two lasers in a row.

[[folder:Cerberus]]
!!Cerberus
!!!'''Rank:''' Lesser Demon
[[quoteright:291:https://static.tvtropes.org/pmwiki/pub/images/statue.png]]
Giant stone statues in the shape of men. Initially seem inanimate, but two of them first wake up to fight you at the entrance to Hell, as the boss of Overture.

* AbnormalAmmo: The energy orbs held by Cerberus are no mere projectiles; they're actually hellish apples on closer examination.
* AchillesHeel: They take 1.5 times more damage from rockets, and double damage from S.R.S Cannonballs, which can knock half their health in one go and outright kill them with a Cannonball Whiplash Parry technique.
* AvengingTheVillain: If any Cerberus falls, all other living Cerberus will [[TurnsRed enrage]] in retaliation.
* BlindedByRage: Cerberus will refuse to tackle over edges unless enraged, after which they can be tricked into falling to their death quite easily.
* DegradedBoss: Proceed to show up as regular enemies from 1-2 and onward.
* DualBoss: You fight two of them at the climax of Prelude, although the second one only joins the fight when you knock the first one's health to half.
* HeWasRightThereAllAlong: The first time they're indicated to be more than just decoration is when the statue on the left side of the Gate of Hell looks up at V1. All statues you see in the game are dormant Cerberuses, and there's no telling which one will spring to life.
* IKnowMaddenKombat: Subtly. Cerberus's throw attack has them take up a very distinct baseball pitching position, and the sound cue for their stomp attack resembles sneakers squeaking on a basketball court.
* KillOneOthersGetStronger: How their Enrage state functions.
* MightyGlacier: Cerberus's movement is slow, and they don't attack often. However, their attacks hit painfully hard and they have 80 HP as bosses and 22 HP as enemies.
* MythologyGag: Cerberus's model comes from an [[https://twitter.com/HakitaDev/status/1432857263497269248 old project]] by Hakita known as "Untraceable", where they were simply a museum statue, now known as Andre.
** Cerberi hold apples. [[https://twitter.com/HakitaDev/status/1432874929087733762 Andre's Apple]]. [[IncrediblyLamePun Untraceable]].
* NonIndicativeName: Cerberus is the name for a three-headed {{Hellhound}} from Myth/GreekMythology, yet Cerberuses are faceless humanoid statues in this game, though they got their name because of their role as guardians of Hell. Even the Terminal Data [[LampshadedTrope lampshades this trope]].
* OurDemonsAreDifferent: [[TheBlank Faceless]] humanoid statues that parody [[ThinkerPose The Thinker]].
* ShockwaveStomp: One of its attacks causes a damaging shockwave.
* ShowsDamage: Their exterior starts cracking once they're at half health.
* ThinkerPose: Their hibernating state has them sitting in a similar pose as the iconic statue.
* TurnsRed: Killing a Cerberus will enrage all other Cerberuses in the fight, making them faster and more aggressive.
* UniqueEnemy:
** The single Cerberus in 1-2, activated by collecting a secret health orb, has more HP than other common Cerberus enemies: 30 HP, to be exact. It is the only Cerberus to have this boosted health value.
** Two giant Cerberi can be optionally found in 7-1, activated again by collecting a secret health orb.

[[folder:Hideous Mass]]

!!Hideous Mass
!!!'''Rank:''' Greater Demon
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/mass.png]]
A malformed demon resembling a scorpion, its flesh rippling out of its stone exterior. Attacks with powerful explosives, giant stone pincers, and its harpoon-like stinger. The sub-boss of Limbo and encountered in 1-3.
----
* AnimalisticAbomination: The Hideous Mass looks like a scorpion-shaped mish-mash of meat and rock, but it's a result of excess Hell energy poured into a single shell.
* AttackItsWeakPoint: Its stone carapace takes next to no damage, forcing you to strike either the exposed flesh or its [[AttackTheTail stinger tail]]. Which one is easier to go for at the time depends on whether it's standing or lying down, but both are equally exposed once it TurnsRed.
* BeastWithAHumanFace: Despite bearing the body type of a scorpion, the Hideous Mass has a large humanoid face just above its vulnerable belly. Less obviously, it has even more faces lining its spine, all of them far less developed.
* BewareMyStingerTail: It can fire a harpoon out of its tail. That being said, the harpoon can be parried with a well-timed Feedbacker punch. Should the harpoon hit you, you can punch it out with the Feedbacker. They start firing it more than once in succession on Brutal difficulty and up, including when they're enraged.
* BigCreepyCrawlies: It's a massive [[ScaryScorpions scorpion-shaped]] demon.
* BlindedByRage: When enraged, Hideous Masses make themselves more vulnerable by flipping upside-down and exposing their underbelly while launching Hell mortars at you.
* DegradedBoss: Hideous Masses can show up during the Cyber Grind, but very infrequently. Because of their large size and immobility beyond pivoting in place, only certain arena patterns can accommodate them. [[spoiler:[[TheBusCameBack Two of them return as mid-bosses in 6-1,]] and another appears in the penultimate encounter of P-2.]]
* EasterEgg: Hideous Mass's forearms have Creator/MichelangeloBuonarroti's [[Art/SistineChapel "The Creation of Adam"]] engraved on them, only visible in its scorpion configuration.
* GlowingEyesOfDoom: Its eye sockets start to glow when enraged.
* {{Leitmotif}}: Hideous Mass is associated with "Castle Vein". [[spoiler:The final encounter of 6-1, characterized by fighting two Hideous Masses, is accompanied by the appropriately-named remix, "Hall of Sacrilegious Remains".]]
* MightyGlacier: They're so slow they can't even move, but not only do they have the most health out of any boss in Act 1, thanks to their ungodly ''[[DamageSpongeBoss 175 HP]]'', they're almost entirely covered in damage-proof stone. Their attacks also hit pretty hard, and they spam a rain of explosives when 2/3rds of their health is gone.
* OurDemonsAreDifferent: A giant scorpion-shaped amalgamation of flesh and stone.
* PivotalBoss: It stays in one spot whenever it's encountered, but will turn to face you.
* ScaryScorpions: It's a scorpion demon.
* ShockwaveClap: It can slam its "pincers" together to fill the area with a vertical shockwave, usually following a ShockwaveStomp.
* ShockwaveStomp: Creating radial shockwaves is one of its attacks.
* TurnsRed: Enrages once it's knocked down to the third of its health, throwing out explosive attacks with greater quantity. Brutal difficulty also lets them throw out their harpoon during this state, albeit infrequently compared to the bombs.
* WhiteAndRedAndEerieAllOver: True to its name, the Hideous Mass is an unsettling creature with a white stone carapace and exposed red flesh.

[[folder:Idol]]
!!!'''Rank:''' Lesser Demon
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/idol_1.jpg]]

Demons that resemble busts of the Virgin Mary. Idols are capable of "blessing" a single enemy, granting them full immunity to damage until the Idol is destroyed. Debuts in 5-2.
----
* AntiRegeneration: Since its blessing prevents enemies from even being ''damaged'', there's no bleeding for V1 to heal from. Thankfully, killing an Idol heals you.
* AscendedDemon: Of a sort, considering they have holy forms, altruistic thought processes, and angelic powers. Unfortunately, Heaven in this setting is too rigid to allow the true version of this trope to happen, and it's even said that if anyone else besides Gabriel had been put in charge of Hell the Ferrymen would have been punished for the blasphemy of creating holy demons by being forced to destroy their beloved Idols.
* BeautyEqualsGoodness. The Idols resemble the Virgin Mary cradling baby Jesus, giving them a holy, beautiful, and kindly appearance unlike their fellow Demons, which either look neutral or horrifying. The Idols are also actively benevolent, and they express their benevolence by using Angelic magic to protect others from harm. This is {{Invoked}} by their Ferrymen caretakers, who carved them into their current forms as a tribute to Gabriel's mercy and as an act of love towards their HappilyAdopted Idols, causing them to feel so beloved they spread the kindness they felt through their divine blessings.
* {{Expy}}: They're essentially Ultrakill's own twist on the Buff Totems from ''VideoGame/DoomEternal''.
* ImmuneToBullets: Idols cannot be harmed by any ranged attack, and must be toppled with a melee strike. Not even the Whiplash can latch onto one.
* HappilyAdopted: Also overlaps with InterspeciesAdoption. The Idols are small, frail, and formless Demons that are adopted by skeletal Husks known as Ferrymen, who raise the Demons with love and compassion by carefully carving them in the image of the Virgin Mary, giving them a chance to experience life with a face of their own. The Idols are so beloved by their Ferrymen guardians that they express the love they felt by protecting others from physical harm with holy magic absorbed from the Ferrymens' divine robes.
* LightIsGood: Idols seem to fall under LightIsNotGood because let's just say that whatever is struck by their blessings is about to ruin your day. That, and they're ''demons'' using angelic magic. However, they protect others solely out of compassion, so in a way, they are good, [[AntiRegeneration just not for V1]].
* LivingStatue: While this is true for all demons, the Idol plays up the "statue" part of this trope more than most others, being fully immobile and incapable of doing anything but blessing enemies and other demons.
* NighInvulnerability: What its blessing grants to its chosen target. Only environmental hazards like pits can kill blessed enemies.
* NonActionGuy: Idols have no form of attack.
* ObviousRulePatch: They're invincible to everything except melee attacks. If they didn't also repel the Whiplash, its grappling hook capabilities would trivialize any encounter where the gimmick is dealing with an Idol placed an inconvenient distance away.
* OurDemonsAreDifferent: Statues of the Virgin Mary that bless nearby enemies with invincibility.
* PricelessMingVase: They're presented as holy relics that can only be defeated by knocking them down with punches.
* ThePowerOfLove: According to their lore entry, the Idols spread the love they experienced by using holy powers to protect others from physical harm.
* ShootTheMedicFirst: Despite lacking any attacks, Idols are placed very high in the "must kill" list due to their ability to buff their allies with invincibility.
* StatusBuff: Its role in any given fight is granting an invincibility buff to its allies, making it a priority target despite being otherwise defenseless.
* TokenGoodTeammate: Unlike their fellow Demons, who attack non-Demons with Hell energy and extreme prejudice, the Idols are actively benevolent for using their holy magic to protect others from harm as an expression of kindness, thanks to being raised with love by the Ferrymen.
* YinYangBomb: Idols are classified as demons, and yet are molded into a sacred form and wield clearly holy magic. This is because the Idols absorbed holy magic from the Ferrymens' holy robes while being carefully carved.

[[folder:Mannequin]]
!!!'''Rank:''' Lesser Demon
[[quoteright:1000:https://static.tvtropes.org/pmwiki/pub/images/mannequin_2.png]]

Humanoid demons resembling mannequins, as their name implies. Debuts in 7-1.
----
* AchillesHeel: As the Terminal tips note, they're briefly vulnerable when they land after getting launched in the air, as they take a second to regain their balance. You could either wait for them to land and take advantage of the stun, or you could rush right up to them while they're still falling and punch them for a OneHitKill. Parrying their punch combo will also OneHitKill them.
* AndIMustScream: The former sinners that are stuffed into Mannequins are still conscious but unable to move by themselves.
* ArtificialBrilliance: Mannequins can dodge their own parried projectiles by hopping onto the ceiling with a well-timed jump, though you can exploit this behavior by shooting them with a rocket as soon as they land on the ceiling, [[AntiAir since it counts as being airborne]].
* BodyHorror: Even more so than other demons, thanks to their upside-down head and limbs being made from severed forearms and hands.
* CantMoveWhileBeingWatched: The first Mannequins shown in the level preview for 7-1 stand still in a pose. Whenever V1 isn't looking, they'll change their pose.
* EliteMooks: Mannequins effectively serve the same role as the ranged Husks in combat, namely standing far away from you and harassing you with projectiles while tougher enemies target you directly. However, they are far more durable than a Husk, have homing shots which can't be easily thrown off and aren't completely helpless at close range, possessing a one-two punch combo. They also aren't afraid to skitter up behind you and actually ''use'' this melee attack like other primarily ranged enemies, making them harder to predict and deal with as a whole. Notably, they're one of the few "small humanoid" enemies in the game which require ''multiple'' Ricoshots from the Marksman revolver to kill.
* FanDisservice: The Mannequins' stone shells have vaguely feminine curves, and they tend to make suggestive poses when idle. However, their blood coating, disfigured limbs, and inhuman skittering motions are far from titillating.
* HomingProjectile: Their ranged attack, a single blue orb like those fired by Mindflayers.
* LightningBruiser: Despite their thin frame, Mannequins are surprisingly durable, thanks to their stony exterior letting them absorb damage from explosions. And unlike other demons, their stony exterior doesn't slow them down; they're ''really damn fast'' and capable of climbing onto walls and ceilings. Lastly, they can dish out the hurt with fast melee attacks and homing Hell orbs.
* MultiArmedAndDangerous: Played with. While Mannequins still have two arms and two legs forming a humanoid figure, said limbs are made out of at least three forearms each, with each joint being formed by a hand grabbing the elbow of the next forearm.
* MurderousMannequin: [[ExactlyWhatItSaysOnTheTin Mannequins]] act as posed statues, but will abruptly spring to life and assault V1 at a moment's notice.
* OurDemonsAreDifferent: Humanoid statues that move terrifyingly fast and can crawl on walls.
* OverdrawnAtTheBloodBank: Mannequins bleed twice as much as most other enemies, spreading their blood further across the arena.
* RunningOnAllFours: The Mannequins crawl on all four limbs like a spider, complete with skittering noises.
* SpidersAreScary: While their only physical resemblance to spiders is their long limbs, their [[RunningOnAllFours four-legged crawling]], ability to climb and crawl on walls and ceilings, and making skittering noises as they crawl give them spider-like qualities that serve to make them even more terrifying.
* SuperSpeed: Mannequins flip-flop between [[TheSlowWalk creeping slowly around]] and skittering around like freakish spiders. Their first encounter in the preview material shows them at an idle standstill, before suddenly accelerating and closing the gap with V1 within a few frames.
* UnwillingRoboticisation: Mannequins are former sinners who tried to escape Violence by going through the Garden of Forking Paths, before eventually collapsing from exhaustion. An unnamed force then tears their weakened bodies apart and stuffs the pieces into a Mannequin shell to make a new one. [[AndIMustScream The victims are still in agonizing consciousness, well after the process is done]], and their hoarse breathing can be very faintly heard emitting from within. The process was directly inspired by the design of the human-fueled Guttermen, as their terminal entry reveals.
* WallCrawl: Their first combat encounter shown as a teaser reveals they can hop straight onto ceilings to take shots at you.
* WhiteAndRedAndEerieAllOver: Mannequins have a porcelain white body that's stained in red blood.

!!Machines
[[folder:In General]]
[[quoteright:1000:https://static.tvtropes.org/pmwiki/pub/images/img_0152.png]]
The Machines are a species of robots that were made to fight for the Final War, [[AlternateHistory an alternate version]] of UsefulNotes/WorldWarI that was centuries longer and more destructive than the original one. These robots were designed to be fueled by blood, which is of divine origin in the Ultrakill universe, and were so effective in combat that human soldiers became obsolete. After the Final War and the Long Night, a period of time where the Earthmovers polluted all the air of the world, humanity stopped everything and started the New Peace, a new era of peace where humanity and Earth slowly recovered from the damage and repurposed all the Machines for other purposes beyond warfare (including creating blood-powered computer terminals, security cameras, construction equipment, and air purification). Upon the discovery of Hell due to a search for new energy sources, humanity sent some Machines to scout the realm until an evil force beyond their reckoning somehow [[AIIsACrapshoot manipulated]] or [[ReforgedIntoAMinion repuposed]] the Machines in order to destroy their masters. Now they all seek blood, either from husks and demons in Hell or from each other on the surface, in a frantic race to stay alive as long as possible before all the blood runs out and they all die from lack of fuel.

----
* AIIsACrapshoot: Maybe, [[spoiler:it's implied that Hell manipulated the Machines into killing everything on Earth for its own sick entertainment after failing to manipulate humanity to kill themselves during the Final War.]]
* AlwaysChaoticEvil: They're an entire race of {{Killer Robot}}s that slaughter every living being they come across to satiate their need for blood, including their fellow machines. According to the Rocket Launcher's lore entry, the robots [[VirtueIsWeakness view cooperation and sharing as a waste of resources]].
* AmbiguousSituation: It is never fully explained the reason why the Machines were specifically designed to be fuelled by blood and only blood. It may have been a case of TooStupidToLive by part of humanity in an attempt to maximize the casualties of soldiers and civilians alike and to make their war machines more effective in combat. [[spoiler:The Terminals imply that Hell [[TheManBehindTheMan manipulated humanity into making the Machines blood-powered to maximize death and enjoy the massacre that would make.]]]]
* CyberCyclops: The Drones and the Sentries all have one pink eye while V1 and V2 have one big yellow eye.
* GangUpOnTheHuman: The machines are supposedly killing each other in addition to Hell's denizens in a frantic dash to get as much blood as possible before it's gone, [[GameplayAndStorySegregation but in gameplay terms]] they'll focus on [=V1=] before anyone and anything else; [[spoiler:[[DownplayedTrope at least until 7-3,]] where the enemies focus on each other as much as they do V1 (to the point where the level's secret mission is to [[InvokedTrope play this trope straight again]])]].
* HumanResources: Machines are powered by blood.
* KillerRobot: All robots are fueled by blood, and they kill to survive. Since blood is a precious yet limited resource, the robots wiped out all surface life [[HumanitysWake along with humanity]], and they invade Hell to slaughter its denizens (and each other) for the precious red fuel.
* MeatSackRobot: [[https://twitter.com/HakitaDev/status/1739247186267816204 According to Hakita]], every robot has organic components installed within their mechanical bodies, hence why they have LudicrousGibs just like the other enemies and bosses.
* MechanicalAbomination: They are an entire species of machines that have not only killed off all of life on the surface of Earth (and may or not be the cause of the extinction of humanity) but are now going down to Hell itself to get more blood in a frantic run to stay active. And the more we find out about their functions, the more eerie they seem - in particular, the fact these blood-powered machines were able to completely dominate warfare and become more or less self-aware artificial intelligence [[spoiler:with technology from the ''1910s'']] indicates there is something ''very'' off about using blood as fuel.
* RoboticPsychopath: An entire race of them, vaguely sentient machines waging war in Hell without any reason other than ensuring their own survival, even if it means slaughtering their fellow robots.
* UnwittingPawn: Much like V1, [[spoiler:Hell has seemingly made the Machines kill all life on Earth and has been luring them into its domain for spreading their violence and conflict everywhere, even if this potentially destroys it in the end. The machines being so utterly crazed for blood as they are, there's so far not a single objection to the matter so long as they can continue to kill and fight as they were created to do.]]
* VirtueIsWeakness: According to the Rocket Launcher's terminal entry, the Machines kill and steal the blood from one another because they see reasonable and long-term thinking strategies such as sharing the blood and cooperating as a waste of resources and they would rather fight.
* TheVoiceless: All the Machines don't talk or make a sound with their voices at all in order to reduce unnecessary usage of energy. The few who avert this are the Swordsmachine, the Streetcleaner, and the Drones.

[[folder:Swordsmachine]]

!!Swordsmachine
!!!'''Rank:''' Greater Machine
[[quoteright:168:https://static.tvtropes.org/pmwiki/pub/images/swordsmachine.png]]
A distinctive machine form with a motor sword and a shotgun. Its original form is unrecognizable after years of scavenging scrap and rebuilding itself, but among scrapheads, the Swordsmachine is quite famous due to its combat prowess and self-made form, ugly to most but beautiful to enthusiasts, spawning many copycats. It wields a self-made sword with a motor on it that, when revved, will heat the blade, cutting through most organic matter with ease. The second sub-boss of Overture, encountered in 0-3.
----
* ArtificialBrilliance: If a Stalker exists at the same time as a Swordsmachine, they will prioritize gunning for the Stalker to coat themselves in sand, before they engage V1. Considering their bias towards close-range combat, out-countering [[HealItWithBlood V1's close-range advantage]] makes them much more of a threat.
* BerserkButton: If any of its sword attacks are parried, Swordsmachine will fly into a rage. Afterwards, it will refrain from using its ranged attacks (its shotgun in phase 1, and its sword throws in phase 2), in favor of barraging its opponent with its melee attacks.
* BlindedByRage: Swordsmachine is mindful of ledges in its normal state, but while [[TurnsRed enraged]], it will completely ignore its own safety in order to lunge at V1. This can be exploited to make a Swordsmachine fall to their doom, especially in Cyber Grind.
* TheBusCameBack: [[spoiler:Returns in Heresy as a DegradedBoss.]]
* CloseRangeCombatant: Swordsmachine likes to fight up close and personal, and its chosen weapons are tailored for this fighting style. Even its ranged options are [[ShortRangeShotgun weapons notorious for]] [[ThrowingYourSwordAlwaysWorks their short range]].
* DegradedBoss: Shows up in the [[EndlessGame Cyber Grind]] [[spoiler:and Heresy onwards]] as a regular enemy. Their lesser HP is justified as these other Swordsmachines are implicitly fans of the original, and aren't quite as bulky as the real deal.
* FamedInStory: Its Terminal entry talks about its fame among other machines, establishing that it has a devoted fanbase whose members modify themselves to copy its appearance. The first of them that V1 encounters are Agony and Tundra in the "Hall of Sacred Remains." [[spoiler:Later, starting with "Cry for the Weeper," less distinguished Swordsmachine copies start appearing as regular enemy encounters.]]
* HoistByHisOwnPetard: Swordsmachine takes bonus damage from shotguns. The same kind of shotgun you steal from him.
* IAmNotLeftHanded: When Swordsmachine enters their second phase (which coincides with them losing their entire off-arm), they start using more wild and flashy [[ThrowingYourSwordAlwaysWorks sword techniques]].
* LineOfSightName: On the receiving end of this trope, from none other than [[https://media.discordapp.net/attachments/1059845568278577354/1190235792388395008/Screenshot_2023-12-29_at_17.08.05.png?ex=65a11076&is=658e9b76&hm=5b692281e781a645bf5b621cf6e90a2adbbe7185bebb4d4378aefa25ca286f54&=&format=webp&quality=lossless&width=2064&height=1068 V1]].
* LogicalWeakness: Swordsmachine is a close-ranged fighter first and foremost; its weakness to shotguns allows V1 to punish Swordsmachine for fighting within its effective range.
* MasterSwordsman: Or Master Swordsmachine to be exact. The Swordsmachine is well respected by other Machines for their impeccable mastery of the sword and they can use their swords like a boomerang.
* MeaningfulName: Take a wild guess of what their name means.
* OptionalBoss: [[spoiler:You can fight it a level earlier in a much smaller room if you find the right secret.]]
* ShotgunsAreJustBetter: The Swordsmachines all wield a shotgun in their right hand and use it periodically.
* SwordAndGun: The Swordsmachine wields a sword in its left hand and has a shotgun welded to its right. Its gunmachineship is not nearly as refined as its swordsmachineship; it's content to simply fire off shots periodically as it runs towards its target, without much regard for aim or distance. [[AnArmAndALeg V1 receives their first shotgun from the first Swordsmachine encountered in the Overture.]]
* ThrowingYourSwordAlwaysWorks: The Swordsmachine's other ranged attack, aside from the shotgun, is throwing their swords like a boomerang and the sword returns to them.
* TheVoiceless: One of the few machines to explicitly avert this in-universe, being equipped with a voice box. In gameplay, this is reflected by the machine making whirring noises when half of its health is taken out.
[[/folder]]

[[folder:Drone]]
!!!'''Rank:''' Lesser Machine
[[quoteright:182:https://static.tvtropes.org/pmwiki/pub/images/drone2.png]]

A flying orb-like machine, firing out Hell Energy. A mass-produced security device built as both a surveillance camera and a security guard. Though originally built to only use non-lethal ammunition, they have scavenged parts from the defunct machines on the surface for greater efficiency at collecting blood. Curious by nature, but to keep production costs low, their intelligence is very limited. They're also the first robotic {{Mook}}. Debuts in 1-1.
----
* AirborneMook: Currently the only fodder-type enemy that flies.
* AnimalMecha: With the bird-like chirping they make when scanning the area, the Drones can be considered robotic birds.
* AttackDrone: They are numerous, flying orb-like Machines that attack V1 with Hell energy.
* BlushStickers: The glowing pink TronLines on either side of their face resemble a cartoony blush.
* ConstantlyCurious: The Terminals describe them as curious by nature and always wanting to learn things, but in order to keep production costs low, the intelligence of the Drones is very small.
* CuteMachines: Despite the Drones can throw at you Hell energy, they certainly are very cute robots.
* CyberCyclops: These robots have one pink eye.
* HelpfulMook: Grabbing them with the Whiplash and then punching them with the Knuckleblaster allows you to send them straight to other enemies, granting the "HOMERUN" style bonus and possibly killing other enemies along with the Drone.
* PurpleIsPowerful: {{Inverted}}. They're purple robots, but even with their TakingYouWithMe attack (which is exploitable), they're the weakest robot enemy in the game.
* StarfishRobots: They're far from humanoid, appearing as floating mechanical orbs.
* TakingYouWithMe: If killed, it will throw itself at you and explode. You can parry that, too, which can [[GrievousHarmWithABody potentially be used to launch their explosive corpse into other enemies to blow them up]]. If killed with an explosion or Piercing Shot, they simply explode on the spot.
[[/folder]]

[[folder:Streetcleaner]]
!!!'''Rank:''' Lesser Machine
[[quoteright:277:https://static.tvtropes.org/pmwiki/pub/images/cleaner.png]]

Humanoid machines equipped with flamethrowers, adept at dodging and relentless in pursuit. Originally built as a way to purify the tainted air of cities after the climate catastrophe, Streetcleaners were made obsolete during the New Peace, and were repurposed as scouts for Hell expeditions. However, their urge to clean remained, and after the fall of mankind, they began burning any organic matter they came across in an effort to purify the world. Debuts in 1-2.
----
* AchillesHeel: A single shot to the gas tank on their back will instantly kill them and cause a huge explosion to boot. This is normally difficult with most weapons since they tend to rush you down, but they're particularly weak to the Marksman as V1 can use it to toss a coin behind them, then shoot it for a guaranteed fatal blow. Since they often come in pairs, savvy players can even use a split-shot coin to instantly kill both of them simultaneously.
* AmbushingEnemy: Their main strategy is to hide until V1 gets close in order to to surprise them before using their flamethrowers to burn the blue robot down.
* DenialOfDiagonalAttack: On Violent difficulty and below, they're incapable of aiming their flamethrowers anywhere but horizontally. This makes going upwards a reliable way to stay outside their flamethrower range if they're otherwise too close for comfort.
* DodgeTheBullet: Streetcleaners are capable of dodging any projectile attack, though this behavior has a short cooldown on it. It's still enough to catch you off guard.
* EliteMooks: Among fodder-type enemies, they're the toughest and most agile. Their weak point is also not easily hit, although hitting it ''will'' kill them.
* {{Expy}}: They look very similar to a B1 Battle Droid of Franchise/StarWars. Even the ULTRAKILL wiki lampshades it.
* FakeUltimateMook: 1-2 hypes them up quite a bit, by all the burning carnage decorating the level once you reach a certain point of the level. You can OneHitKill them with a simple coin ricochet [[FlamethrowerBackfire into their gas tank]].
* FireBreathingWeapon: All of them are equipped with flamethrowers to ignite you in close range.
* FiveSecondForeshadowing: They have a particularly memorable introduction in 1-2. After picking up the blue skull key, the path to loop back around will take you around a bend in a hallway... to reveal a giant pile of burning, dead Husks. Cue MusicalisInterruptus and an ensuing DroneOfDread as you soon return to the courtyard area you started, only to find it's all on fire as well -- with some Streetcleaners near the entrance room.
* FlamethrowerBackfire: Hitting the gas tank on its back will cause it to explode and kill Streetcleaner on the spot. You can even blow up gas tanks of dead Streetcleaners!
* HoistByHisOwnPetard: When dodging V1's projectiles, Streetcleaners can sometimes dive into environmental hazards, especially BottomlessPits. This is particularly noticeable when they appear in the staircase area of the "Belly of the Beast"; the paths aren't wide enough to accommodate their movements when dodging perpendicular to them.
* KungFuProofMook: The only enemy in the game to actively deflect a Core Eject grenade by smacking it aside. It also makes a conscious effort to dodge projectiles. Additionally, Streetcleaners are capable of walking on the hot sand in Greed without any issue. Lastly, they have an innate resistance to explosives in general, taking only half the normal amount of damage from any explosion.
* LogicalWeakness: Streetcleaners' ability to deflect grenades and rockets makes them very annoying to deal with, however since they use their hands to do this, they can't reach explosives fired ''behind or above'' them.
* MeaningfulName: The Streetcleaners were once robots made to clean the pollution on the streets that were formed during the Final War. Now they [[Main/{{Subverted}} subvert]] their purpose of cleaning everything by using their flamethrowers, making things even messier.
* NoRangeLikePointBlankRange: There is an obvious risk in dashing up to something that's packing a flamethrower, but if you ''really'' don't want them to dodge your shots, getting in their face and blasting them will usually work; they'll be both too close to react and too distracted trying to burn you. Just remember to dash back out.
* ParryingBullets: Streetcleaners will smack aside Core Eject grenades and rockets that are fired directly toward them.
* Main/{{Pyromaniac}}: The Streetcleaners have an urge to clean since that was their original purpose, but since they all have flamethrowers instead of cleaning devices, they enjoy burning everything to a crisp instead.
* ShoutOut: Their name is a reference to the debut album of Music/{{Godflesh}}.
* SuperDrowningSkills: Submerging them in any liquid will instantly kill them.
* VaderBreath: You can tell when a Streetcleaner is nearby by their mechanical breathing.
* YouHaveResearchedBreathing: The main change to Streetcleaners in the Brutal difficulty compared to lower difficulties is... the ability to aim their flamethrower upward.

[[folder:Mindflayer]]
!!!'''Rank:''' Greater Machine
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/mindflayer.png]]

A greater machine form with excellent control of Hell Energy and its own enhancements. The machine itself is only the top part of its apparent body, the rest of which is a plastic shell in the form of a human, which they seem to have built themselves. The plastic body serves no function and is only for aesthetic purposes. Despite it being a waste of resources, Mindflayers will use everything in its power to protect the plastic body from harm, even if that means destroying itself in the process. Mindflayers seem to prefer a female form, though very rare occasions of male forms have also been recorded. Throws out devastating attacks from above. Debuts in 2-3.
----
* AmbiguousSituation: The Terminals don't explain what were the Mindflayers made for, so it's unclear if they were made for warfare or for another purpose.
* AntiFrustrationFeatures: Due to how dangerous they are in Cyber Grind, a Mindflayer won't show up in two rounds in a row. If two Mindflayers show up during a round, they won't show up for two rounds, and so on.
* AttackItsWeakpoint: Surprisingly, Mindflayers do have weakpoints: [[BoomHeadshot their head]], and the protrusions on the back. Their tentacles take extra limb damage as well. Unfortunately, attacking their weakpoints is difficult, due to their small sizes and how mobile Mindflayers are.
* BarbieDollAnatomy: They're purportedly naked, but show no attributes. Justified, since their "bodies" are actually just plastic shells.
* BossInMookClothing: There are only four of them in Act 1 and they only show up at its tail end, but each of them is a sturdy foe with powerful attacks. Like bosses, Mindflayers can be enraged in Violent difficulty and above. Punching them earns you the Disrespect bonus as it does with all other bosses and {{Degraded Boss}}es, too. To top it all off, they're the only "Special"-class enemy in the Cyber Grind that wasn't a boss at first (with the others currently including the Insurrectionist and the Ferryman).
* CombatTentacles: They have five tentacles on their back, and they can be used for a parry-able melee attack.
* DarkActionGirl: The Mindflayers are [[{{Fembot}} fembots]] that shoot Hell energy and attack with their tentacles. And they are all [[KillerRobot killer robots]] that are literally bloodthirsty, having exterminated, alongside the other Machines, all life on Earth.
* FastballSpecial: As Mindflayers are self-destructing, a quick punch with the Knuckleblaster can send them hurtling in any direction. They prove to be quite deadly projectiles.
* {{Fembot}}: Mindflayers appear to be feminine robots, but according to the Terminal Database, what appears to be their body is just a plastic humanoid shell that serves no purpose other than aesthetics, and the machine itself sits on the shell's upper half. Mindflayers with masculine shells are mentioned, but they have yet to appear in-game.
* HoistByHerOwnPetard: It's possible to reflect Mindflayer's blue projectiles into her and kill her in one shot. Unlike Malicious Face's Chargeback, there are a couple of ways to do it (parried shotgun pellets, Core Eject, Malicious Railgun, etc.) but they require different precise timings and a whole lot of skill.
* HomingProjectile: Mindflayers fire blue orbs of Hell energy that home in on V1.
* KrakenAndLeviathan: It's subtle, but the Mindflayer falls under the Kraken side of this trope, thanks to its CombatTentacles and its 1st Act II appearance in the watery Wrath layer.
* LightningBruiser: Especially when compared to other enemies, Mindflayers are fast and tough, thanks to their whopping 30 hitpoints, the ability to teleport, and having dangerous attacks that deal 30-35 points of damage, such as a deadly melee swipe, a series of homing Hell orbs, and laser beams.
* MeaningfulName: Main/{{Subverted}}: as far as we have seen, the Mindflayer doesn't have an attack that affects the mind. [[AmbiguousSituation Or maybe they just haven't used it on V1 yet.]]
* MidairBobbing: Mindflayers slowly move up and down when idle.
* MsFanservice: They are a type of Machines that consists of [[{{Fembot}} Fembots]] that made a curvy and teal plastic body and are supposedly the [[SuccubiAndIncubi succubus]] enemy of the game.
* ShoutOut: The Mindflayer robots share their name with the Mind Flayers of TabletopGame/DungeonsAndDragons, a humanoid species of octopus-headed aberrations with immense mental power.
* SuccubiAndIncubi: According to WordOfGod, the Mindflayer was designed as a unique take on the "succubus" concept. In-game it's PlayedWith, as they're Machines wielding hell energy rather than truly native to Hell. The fact that they first appear in Lust does reinforce this concept.
* TakingYouWithMe: Upon death, Mindflayers will reel in pain for a few seconds before exploding. They can be punched with the Knuckleblaster while they're reeling, sending them flying into the nearest surface or enemies and detonating on contact. According to their database entry, their self-destruction isn't an intentional last-ditch attack; [[IfICantHaveYou it's meant to to prevent anyone else from claiming their bodies after they die]].
* TeleportSpam: The Mindflayers can teleport around the arena and they do this very frequently.
* TurnsRed: On Violent difficulty and above, Mindflayers will enrage once reaching half health, increasing their attack speed and [[TeleportSpam frequency of teleports]].
* VanityIsFeminine: They make their own bodies in the shape of a feminine human form, with masculine Mindflayers existing as a rarity. They're also obsessed with maintaining their bodies to the point of self-destructiveness, even though it serves no objective purpose.
* VillainTeleportation: Mindflayers can teleport across the area, and while the Screwdriver Railcannon keeps them from teleporting, it barely mitigates the threat they're capable of.
* YouWillNotEvadeMe: Mindflayers will teleport right on top of V1 should they become too far away to reasonably attack otherwise.

[[folder:Sentry]]
!!!'''Rank:''' Greater Machine
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/ultrakill_wrathsentry.png]]

Essentially a high-powered rifle on legs, Sentries first show up in Wrath. One of the many war machines created during the Final War. Although there were attempts to find a new purpose for them during the New Peace, their streamlined design made them unable to be repurposed until the start of the Hell expeditions. They hunker down and blast targets with a potent sniper beam. Debuts in 5-1.
----
* AchillesHeel: The easiest way to knock a Sentry out of its lock-on is by hitting its antenna with a hitscan attack, or blasting it with a kind of forceful knockback. Continous use of these can render a Sentry completely unable to use its strongest attack.
* AlwaysAccurateAttack: Sentry shots will always hit their target. If you can't prevent them from shooting, finding cover or the invulnerability frames of a well-timed dash are the only ways to avoid damage.
* AnchoredAttackStance: When preparing their sniper shot, Sentries will get down on both knees and root themselves to the ground. Knocking them out of this with explosives, magnets or a well-placed stomp/Knuckleblaster punch is key to dealing with them because they can't shoot V1 if they can't anchor themselves.
* AnArmAndALeg: Sentry legs are apparently prized among scrapheads due to their exceptional utility and durability, and it is implied that V2 created the Whiplash from one.
* ArmlessBiped: The Sentry's body consists only of a pair of mechanical legs, a torso, and a sniper rifle where a head should be.
* {{BFG}}: Their ''head'' is one.
* ColdSniper: The Sentries are a type of Machines that consists of robotic legs with a sniper rifle at the top of their torsos where their head should be. Given the fact that the Machines are AlwaysChaoticEvil, the Sentries are most likely this.
* CripplingOverspecialization: The codex notes that their extremely minimalist design made it hard to apply them for purposes that weren't for war when war had ended.
* CyberCyclops: All the Sentries have a single pink eye to track V1 with a laser sighting.
* ExtremityExtremist: Attacks at close range exclusively by kicking you. [[ArmlessBiped Not that they have much of a choice...]] Unlike many melee attacks, this kick cannot be parried; luckily, the attack has a distinctly telegraphed wind-up, both audibly and visually.
* EvilIsBigger: Their legs alone dwarf V1 and they're laser-focused on shooting the machine down.
* {{Hitscan}}: One of the few enemies to have this attack type.
* HoistByHisOwnPetard: Since the Sentry's sniper beam attack is a powerful hitscan shot, it can be reflected back at them with a coin for a Chargeback.
* LaserSight: You can tell a Sentry is tracking V1 by the laser sighting between the two.
* MadeOfIron: Sentries are a lot more durable than their relatively thin frame would suggest.
* PunchedAcrossTheRoom: Get in their faces and they will try to nail you with a highly-telegraphed, but oddly powerful (and unparryable) kick that ''will'' send you sailing across the room, where shooting you is easier.
* RobotAntennae: All the Sentries sport one at the top of their heads and it signals when they are going to shoot.
* SentryGun: A fully-autonomous example. When not walking around, they function as one.
* SpamAttack: Brutal difficulty lets them fire ''two'' shots in succession instead of one.
* UnusualWeaponMounting: They have a high-caliber anti-material rifle replacing their head.
[[/folder]]

[[folder:Gutterman]]
!!!'''Rank:''' Greater Machine
[[quoteright:643:https://static.tvtropes.org/pmwiki/pub/images/bigdaddy.png]]
A big bulky machine with a shield and a rotary cannon that first shows up in Violence. Built in the early days of the Final War, the Guttermen were one of the first successful experiments in using blood as a fuel source, as well as the first automatons to be deployed in wide-scale conflict. Debuts in 7-2 as a sub-boss before quickly becoming a recurring enemy.
----
* AchillesHeel: Their shields can be removed by a Knuckleblaster hit, whereupon their punches can be parried with the Feedbacker which also resets their chaingun tracking. Their Chaingun shot, strangely enough, can be reflected with coins. Also, they go down in one hit by punches from Guttertanks.
* AndIMustScream: The humans that were used as blood batteries for the Gutterman most likely didn't enjoy a single bit of being inside a very small sarcophagus while having their blood sucked out of them and used as fuel for the Machine.
* DegradedBoss: One Gutterman is your first enemy in 7-2, and is given its own health bar. It immediately starts appearing in encounters after the fact, having slightly less health.
* DropPod: Its method of arriving at the fight.
* {{Expy}}: Of [[VideoGame/BioShock Big Daddies]]. They're huge, heavily-armored {{Smash Mook}}s, their lore mentions that they were originally powered by undesirables permanently grafted inside them to provide them a permanent blood source, and their helmets look very, very similar to Bouncers.
* FatBastard: Its build is notably large and rotund, and it's not just a literally bloodthirsty KillerRobot, it also happens to fulfill the "chaingunner" archetype of StandardFPSEnemies; one of the most notorious roles in gaming.
* GatheringSteam: The Gutterman is slow to aim its chaingun at first, but its tracking gets more accurate over time. This necessitates V1 to stay mobile and deal with it quickly, lest it becomes nigh-impossible to avoid evade the Gutterman's shots without taking cover. When its shield is destroyed, it uses its newly freed hand to steady its aim, and its tracking dramatically improves.
* GatlingGood: The Gutterman has a massive chaingun that tracks V1's position and continuously fires.
* HelpfulMook: When killed, they will instantly kill any enemy they fall on, giving you the "Pancaked" style bonus. Also, performing a ground slam on their corpses will create a red explosion that is harmless to V1, but will blow nearby enemies into bits.
* HumanResources: A close look at their ammo backpack (which is shaped like a coffin) shows the human skeleton inside with [[TearsOfBlood red streaks staining the cheekbones]]. This is how Guttermen are fueled, as they were among the first machines designed to run on blood: this is the only way they could keep their blood fresh. [[spoiler:The Gutterman's terminal entry notes that this was so imaginatively cruel that it directly inspired the creation of [[MurderousMannequins Mannequins]].]]
* HuskyRusskie: The letters on their shoulders are in Russian which translated means "man-tank", implying that the Guttermen are of Russian origin. They are also one of the strongest non-boss enemies of the game.
* IndignantSlap: The Gutterman's alternative to the ShieldBash should it not have its shield. Unlike the shield bash, it is parriable by normal methods (i.e. the Feedbacker).
* LuckilyMyShieldWillProtectMe: It carries a massive shield that protects itself from most attacks. V1 can destroy it using the Knuckleblaster.
* MightyGlacier: What it lacks in mobility, it makes up for in bulk and [[MoreDakka firepower]].
* ShedArmorGainSpeed: If their shield gets destroyed, a Gutterman will start aiming its minigun with both hands, significantly increasing its tracking speed.
* ShieldBash: Should V1 get too close to a Gutterman (and thus out of its ideal tracking range), the Gutterman will respond by smacking V1 with its shield. The Knuckleblaster, uniquely, can parry this to destroy the shield.
* SmashMook: They will perpetually fire at you with their deadly gatling guns when you're far away and batter you brutal punches when you're up close, making them high-priority targets.
* ShieldBearingMook: Paired with a nigh-indestructible shield and a gatling gun, they're very tough to deal damage to unless you destroy their shields with the Knuckleblaster.
* SuperPrototype: They were the first generation of Machines that would use blood as fuel and they are amongst the most powerful enemies of the game that aren't bosses. Because scientists back then didn't know how to keep the blood of their enemies fresh, they used [=POWs=], renegades, or returnees of the war as batteries for the Guttermen.
* PinnedDown: The main role of the Gutterman in combat encounters is to provide a steady stream of suppressive fire that forces V1 to stay moving. Its gunfire can also intercept V1's projectiles (specifically coins, core ejects, and rockets), making these specific weapons much more difficult to use while a Gutterman has a bead on you.
* TopHeavyGuy: Most of the Gutterman's frame is proportionately taken up by its colossal torso. Its legs, on the other hand, are incredibly small and downright stubby.
* TurnsRed: Breaking their shield or parrying them afterwards on Brutal difficulty and above enrages them, making their close range slap unparriable until it wears off.
[[/folder]]

[[folder:Guttertank]]
!!!'''Rank:''' Greater Machine
[[quoteright:666:https://static.tvtropes.org/pmwiki/pub/images/img_0163.png]]
Created in response to the Gutterman, these machines are much more nimble and armor-plated. They come equipped with an array of explosives designed to smash the heavy armor of Guttermen and are more than capable of splattering machines like V1. Debuts in 7-2.
----
* AchillesHeel: Their rocket launcher utilizes the exact same technology as the one V1 uses, meaning that activating the Freezeframe will freeze Guttertank rockets as well. It also means that sticking a nailgun/sawblade launcher magnet to them will significantly gimp their range (since their rockets are just as attracted as yours), letting you pelt them at range and potentially causing friendly fire if there's more than one.
* AntiMetagameCharacter: In-universe. Guttermen completely changed the tactics of the Final War with how deadly they were, so Guttertanks were created specifically to counter their trench-clearing abilities.
* ArmCannon: Their right arm is a cannon that shoots missiles from it. V1 can ride on them like the missiles of their own rocket launcher.
* CherryTapping: After update [=14b=], if a Guttertank whiffs its punch, it will smack the ground and cause a small amount of damage to itself. If this somehow kills the Guttertank, you'll earn a +SLIPPED style bonus.
* DestructibleProjectiles: Guttertank rockets can be shot with a hitscan weapon, causing them to explode prematurely. This is something that gives the Guttermen an edge in skirmishes with Guttertanks; if a Guttertank is focused on another target (i.e. V1), a Gutterman can make its life very difficult by intercepting each rocket before they reach their target.
* FriendlyFireproof: An individual Guttertank is immune to its own rockets (including their splash damage) unless you take the time to pause ''and'' ride them, even briefly. Even if you freeze the rocket and stick a magnet to the Guttertank, the rocket will refuse to make a collision and just sort of ''tickle'' the thing until it goes off to no effect. Multiple Guttertanks ''can'' damage each other normally though.
* GameplayAndStoryIntegration: The Guttertank's terminal entry explains that they were designed to smash Guttermen shields with ease. Indeed, should a Guttertank focus on a Gutterman, one punch from the former kills the latter instantly, shield or not.
* GermanicEfficiency: The Guttertanks are of German origin, judging by the words 'Faust Panzer', a pun since they are a tank that punches, written in their left hand. They were also made as a counter to the Gutterman and they are good at killing them, so good that they just need to hit them once.
* HoistByHisOwnPetard: Every single one of the Guttertanks' attacks can be turned against them:
** Parrying a landmine as it bounces, and launching it towards the Guttertank that deployed it, will deal heavy damage and earn a +LANDYOURS bonus. Parrying them is also a highly convenient source of healing when getting close to catch the blood splatter is just asking to get {{Megaton Punch}}ed out of range.
** Freezing a Guttertank's rocket, then riding and steering it back to the Guttertank, will instantly kill it and earn a +ROUND TRIP bonus.
** If the Guttertank misses their punch--which itself cannot be parried--it will trip over and take a few seconds to stand back up. This period of time has a parry window, and V1's fantastic mobility means they'll have no trouble baiting a Guttertank into a vicious cycle of attempting to punch them, falling, then getting countered. The tripping itself does a slight amount of damage, meaning it's possible for the Guttertank to kill itself this way, earning V1 the +SLIPPED style bonus.
* InstantDeathRadius: Downplayed in the initial build in that you would (probably) not die instantly, but if you got anywhere close to a Guttertank it would cue a lightning-fast haymaker that would launch you into the nearest wall, disorienting you and setting you up for a rocket. Getting in their faces to heal was rarely an option. Guttertanks were even smart enough to wind up a punch if you Whiplash them; by the time the distance closes, it would land. However, this attack was nerfed shortly after Layer 7's release, by way of adding self-inflicted ScratchDamage and a longer recovery animation to the punch during which it can be parried - but ''only'' if it misses, and even then this nerf is absent on Brutal difficulty and above.
* LightningBruiser: Despite being built like tanks, these war-crime engines are deceptively quick, as are their hard-hitting--and ''numerous''--explosive attacks.
* MegatonPunch: A Guttertank's punches can knock out a Gutterman in one single blow, and can send V1 flying.
* PunnyName: Their German name is an inversion of "Panzerfaust", a bazooka-like anti-tank weapon.
* ShoutOut:
** The ArmCannon of the Gutterank can be seen as a reference to [[Franchise/{{Metroid}} Samus Aran]] since it looks very similar to the bounty hunter's own weapon.
** The Guttertank's entire design makes it look like a Dreadnought from Franchise/Warhammer40000.
* ThrowDownTheBomblet: Guttertanks can deploy land mines, which will bounce upward when an enemy approaches them. In their short air time, V1 can parry these.
* TrapMaster: Guttertanks plant down landmines that can catch you off-guard if you're not expecting them. In one specific example from 7-2, a Guttertank and Gutterman will ambush you when you revisit a place you've already been, with landmines already covering the area so they have the home turf advantage.
* WalkingTank: They're machines that ''strongly'' resemble tanks, and the German text on their fists is "Faustpanzer", which translates to "Fist Tank".

!!Angels
[[folder:In General]]
The Angels are inhabitants of Heaven, possessing an explicit social hierarchy. Lesser Angels are abstract beings similar to Husks, as they are human souls with their appearance based on their prior life's worth and virtuousness. Greater and Supreme Angels are born in Heaven, consistently humanoid in appearance, and not very fond of life forms deemed below them, including their fellow Lesser Angels.
----
* FantasticRacism: The Angels view non-Angels as inferior, which is why they look down on Lesser Angels by giving them menial tasks due to their human origins.
* OurAngelsAreDifferent: Lesser angels are made out of [[OurSoulsAreDifferent human souls]] and their forms are either animalistic or [[AngelicAbomination surreal]]; greater and supreme angels take on more traditional [[WingedHumanoid humanoid forms]] because they're born from Heaven. Heaven also has a fiercely segregated class system where angels made from human souls are determined to be impure compared to angels that were born that way, and thus given busywork or other unwanted tasks that higher level angels deem unworthy.
[[/folder]]

[[folder:Virtue]]
!!!'''Rank:''' Lesser Angel
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/ultrakill_virtue.png]]
An angelic being that summons damaging pillars of light on the battlefield. They're also the first angelic {{Mook}}. Debuts in 4-1.
----
* AlwaysAccurateAttack: As long as a Virtue is spawned, they can and will attack from anywhere, regardless of whether V1 is behind cover or far away. Fortunately, the beam has an obvious telegraph for when it's about to strike: an ornate pattern begins following V1 on the ground directly below them, and it'll stop tracking a second before actually calling down the beam. Functionally, the attack is intended to encourage players to keep moving until they find its source. If the Virtue isn't killed in time, it'll start leading its attacks out of anger, adding yet more challenge.
* AngelicAbomination: It's a prism surrounded by a golden halo with wings that summons destructive pillars of light.
* AntiFrustrationFeatures: While Virtues usually enrage if they miss enough attacks, they will not enrage if there are three or more present.
* BlownAcrossTheRoom: When killed, Virtues fall to the ground and create a harmless explosion that pushes V1 away. Their corpses can be parried to damage enemies, however.
* CombinationAttack: If multiple Virtues are present, they stagger their light beam attacks so they happen consecutively, significantly increasing the danger they pose.
* EliteMook: While Virtues have only one attack, said attack is a devastating pillar of light that [[ArmorPiercingAttack ignores cover]]. They can also be enraged like bosses.
* EyesDoNotBelongThere: In the lore, only. Apparently, the wheels that make them up are supposed to be covered in eyes like biblically accurate depictions of Thrones, but the codex comments that they have lost them. It's theorized to be an aspect of them manifesting in hell, as the same codex points out the vast majority of Hell's denizens are also lacking any eyes.
* HolyHandGrenade: Their light beams are weaponized Heaven magic.
* InterspeciesFriendship: Virtues are Angels born from human souls, and they're often paired with Idols, Demons wielding holy magic. There are three notable Virtue/Idol encounters in 5-2, 5-3, and 6-1. Considering their respective lore entries [[spoiler:(Virtues and their fellow Lesser Angels are looked down on by higher-level Angels due to their human origins, and Idols are Demons raised with love by the Ferrymen, who themselves are former humans, and use holy powers to express kindness), the Idols' blessings are the [[ThrowTheDogABone first kindness the Virtues ever felt since they first became Angels]].]]
* LightIsNotGood: They're divine winged orbs that will kill you with pillars of light.
* OurAngelsAreDifferent: Divine, winged prism orbs that [[WasOnceAMan used to be humans]].
* PillarOfLight: They smite V1 with their one and only attack: summoning large pillars of holy light.
* TurnsRed: If left unattended for too long, it will enrage, summoning pillars more often and predicting your movement while doing so.
* WasOnceAMan: Like all Lesser Angels, Virtues are humans who entered Heaven upon death. They're basically Heaven's equivalent to Hell's [[OurZombiesAreDifferent Husks]].
[[/folder]]

!!Other Enemies
[[folder:Puppet]]
!!!'''Rank''': Unknown
Animate, featureless, humanoid masses of pure blood that are found exclusively in 7-3, and only around the larger trees V1 must "feed" by watering them with the blood of Puppets.
* TheBlank: Their default form as seen in their first encounter and the sandbox is absolutely featureless.
* DittoFighter: Three out of the four encounters with them have them mimic previously-encountered enemies - the Filth in the second, the Stray in the third, and the Mannequin in the fourth and last encounter.
* HumanoidAbomination: They are featureless translucent beings seemingly made of blood forming a human-like shape capable of mimicking some denizens of Hell, coupled with the tendency to appear near particular trees and their blood being used to "feed them".
* TheSpook: They have no Terminal entry of their own, so what they are is a mystery.
* UniqueEnemy: They only appear in one level in the whole game, can mimic other enemies, and killing them is actually used to fulfill an objective, in their case feeding the trees.

!Regular Bosses

[[folder:[=V2=]]]

!!V2
!!!'''Rank:''' Supreme Machine
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/v2_2.jpg]]
A red combat robot not unlike V1 that seems to venture to Hell for the same purpose. The boss of Limbo [[spoiler:and returns as the boss of Greed.]]
----
* AnArmAndALeg: Loses an arm as a result of their [[spoiler:first]] boss fight. [[spoiler:An arm is all that remains of them after their second boss fight.]]
* BackForTheDead: [[spoiler:V2 comes back for a rematch in 4-4, only to fall to their death at the end of the battle.]]
* BerserkButton: V2 has two requirements for their rage status, [[spoiler: one of which only turns up in the second encounter]]. For the duration of their rage, they switch to their extremely aggressive red-wing mode:
** In Clair De Lune, they flip out if V1 keeps their distance for too long. Oddly enough, punching them in this fight doesn't count as a +DISRESPECT bonus.
** In [[spoiler: Clair De Soleil]], they become outraged whenever [[spoiler: V1 punches them with their original arm, the Knuckleblaster.]]
* CantCatchUp: After being defeated the first time V2 acquires a nailgun and learns to use coin shots, allowing them to replicate the tactics V1 used in their first battle. Unfortunately V1 has got stronger still in the meantime, acquiring a railgun as well as V2's old arm, meaning they still have a bigger arsenal.
* CoinTargetingTrickshot: The rematch against V2 in 4-4 has them [[MirrorBoss copy the player]]. This means they also can do coin trick shots, being able to deal hefty damage. This is used to show how much they have learned since the previous boss battle, along with being a test for the player to see if they can outperform the boss by making them have to shoot the coins thrown in the air before V2 beats them to it. Also, while they can shoot coins in the first boss battle and cause them to ricochet, they won't outright do so and can only be on accident, such as if the player just so happens to throw a coin right in front of V2 as they are shooting.
* ColorCodedForYourConvenience: V2's wings change colors depending on their behavior. When V2's wings are red, they will try to stay close to V1 and constantly attack them with everything they have. When V2's wings are green, they will instead keep their distance and refrain from using their weapons as frequently. Yellow and blue wings both signal a middle-ground behavior between V2's aggressiveness with red wings and passiveness with green wings.
* CombatBreakdown: [[spoiler:In their second appearance. During their second phase, in which both V1 and V2 are sliding down the pyramid, V2 can only dash when fought up-close, making landing attacks on them much easier.]]
* CruelAndUnusualDeath: [[spoiler:V2 meets their end after V1 knocks them out of the pyramid they were both fighting on and crushes onto the floor, leaving only their new grapple arm and a big puddle of blood.]]
* CyberCyclops: Just like V1, V2 has a large yellow singular eye on their head.
* FauxAffablyEvil: Begins the first bout with them with a courteous bow, but has no intention of being honorable or level-headed when it comes to attacking [=V1=].
* ForgotAboutHisPowers: Despite having both the Knuckleblaster and later the Whiplash at their disposal, they never utilize either in their attack moveset.
* FragileSpeedster: Amongst Ultrakill's bosses and minibosses, they're one of the most mobile and evasive of the bunch, but they also have the least amount of health amongst them; they only have 40 HP in Act I compared to the Hideous Mass's 175, The Corpse of King Minos' 160, [[DiscOneFinalBoss Gabriel's]] 100, or even the Prelude's Cerberus which has at least 80 for each instance. [[spoiler:Even in Act 2, this continues: They only have 80 HP total, which is even less than ''Gabriel's rematch'' in 6-2, who still retains his 100 total HP from his last bout in 3-2.]]
* GameplayAndStorySegregation: Whilst the 1-4 terminal entry for V2 states that they were made with standardised plating due to ''durability'' being more important after the war, V2 has in fact, ''less'' health than [[GlassCannon V1]] in practice, bearing 40 HP in Clair de Lune [[spoiler:and 80 HP in total (50 during the first phase, 30 during the second phase) in Clair de Soleil]], compared to V1's 100. [[SubvertedTrope However]], close inspection of the data reveals that V1 only has 10 health, which is rendered as 100 in-game for the sake of readability, and in gameplay, they are much more fragile than V2 is, only managing to best their successor through superior maneuvering and aiming.
* HealthDamageAsymmetry: Justified; despite V1 and V2 using the same weapons, V2 is able to soak up way more damage than V1. This is because V2's armor is stronger, but at the cost of not having the same blood absorption that V1 can do.
* HoistByHisOwnPetard: They use a few new tricks [[spoiler:in their second encounter in the Greed layer]], and both of them can be turned against them in different ways. Both counterstrategies are cited in V2's second terminal entry.
** V2 periodically throws Marksman coins, interacting with them almost identically to how the player does. The sole difference is that the last coin in their ricoshot chain doesn't launch at the player immediately; before it does, it freezes in midair and flashes red for a brief moment. This gives V1 a chance to shoot V2's coins back at them, doing decent damage and earning the "Counter Ricoshot" bonus in the process. Meanwhile, if V1's slow with ''their'' coin shots, V2 can ''also'' perform Counter Ricoshots--but the same pause and red flash both occur for them, allowing V1 to counter their counterattack.
** The nails from V2's nailgun attacks can be neutered completely with V1's Attractor magnets. As soon as the nails are attracted to a magnet, their ownership will transfer from V2 to V1, becoming completely harmless to the latter and, thanks to nailbombing, potentially dangerous to the former. Conveniently, the Attractor Sawblade Launcher can be found a few rooms before this fight, implicitly encouraging this tactic.
* NotTheFallThatKillsYou: Averted. V2 attempts a second daring escape from V1 by sliding down the side of the Greed Pyramid, but V1 manages to knock them into the air in such a way that they ''[[ChunkySalsaRule instantly liquefy]]'' the second they hit a flat surface on the ground.
* KilledOffForReal: V2 tries escaping V1 in [[spoiler:Clair De Soleil]] by [[spoiler:sliding down Greed's biggest pyramid.]] However, when V1 follows and damages them enough, [[spoiler: they're sent tumbling so hard that they sail into the air and splatter at the pyramid's base headfirst, leaving nothing behind but the Whiplash arm. If anyone thinks V2 ''somehow'' survives, their 2nd database entry makes it clear that V2 is already killed after their final defeat in Greed.]]
* {{Leitmotif}}: V2 is associated with a recurring soft guitar riff, which serves as the basis [[https://m.youtube.com/watch?v=BhEnjxYLBYo&pp=ygUQVWx0cmFraWxsIHZlcnN1cw%3D%3D Versus]] during their fight in Clair De Lune and [[spoiler:[[https://m.youtube.com/watch?v=ZFw0n198f4o&pp=ygUOVWx0cmFraWxsIGR1ZWw%3D Duel]] for their fight in Clair De Soleil]]. While calm, the motif paints V2 as sinister and competitive, and it quickly gives way to heavy percussion, synths, and guitars as they start fighting.
* LightningBruiser: Shares their mobility and arsenal with V1, but their thicker and stronger armor plating makes them a Hell of a lot more durable.
* MirrorBoss: For the most part, V2's got access to your own tools, both weapons and movement techniques.
* NoPlansNoPrototypeNoBackup: [=V2=]'s lore entry notes that neither they nor [=V1=] reached mass production, so it's likely only a single model of either was ever built.
* PintSizedPowerhouse: They're as tall as V1, who's shorter than a Filth themself, but they're just as formidable as their predecessor.
* SlouchOfVillainy: [[spoiler: Begins the second fight with you lounging on a throne. Sadly you can't get a cheap shot on them while they're sitting.]]
* SuperiorSuccessor: To a degree. Superior durability gives V2 a wider range of tactical options in the short-term, but their lack of blood absorption leaves them vulnerable to being worn down.
* TurnsRed: In 1-4, keeping your distance for too long enrages V2. [[spoiler:In 4-4, hitting V2 with their original arm enrages them.]] While enraged, their move speed is increased ''drastically'', outpacing even V1's dash-jumping speed, and they gain the ability to [[TheComputerIsACheatingBastard spam charged Piercer shots]].
* UpgradeVsPrototypeFight: V2 is the successor to V1, having superior armor plating at the cost of absorbing blood through contact. Despite the improved durability and having combat skills equal to V1's, V2 lost [[spoiler:twice]].
* VictorGainsLosersPowers: [[spoiler:In their 2nd database entry, V2 stole an arm from a nondescript robot they killed (implied to have been a Sentry), then modified it with scrap parts. V2 is on the receiving end of this trope twice, with V1 taking both arms at the end of each battle, including the new one.]]
* VillainExitStageLeft: V2 flees at the end of the battle with them. [[spoiler:They try this again in their rematch, but V1 pursues after them to make sure they don't come back.]]
* WakeUpCallBoss: V2 is the game's first notable difficulty spike. They are a tough, mobile, hard-to-hit, and hard-hitting foe that tests the player's ability to not only aim well, but also avoid damage at the same time. Healing from V2 also requires knowing how to take advantage of the cooldown between V2's attacks.
* WingedHumanoid: Also like V1, V2 is a humanoid robot with yellow wings.
* WingsDoNothing: Yet again, also like V1, V2's wings are [[{{Inverted}} used for anything but flight]], such as sliding, dashing, and storing weapons.

[[caption-width-right:350:[[labelnote:Click here to see the [[spoiler:parasites infecting him.]]https://static.tvtropes.org/pmwiki/pub/images/snakeeyes.png[[/labelnote]]]]]]
The desecrated remains of King Minos, the former ruler of the Lust layer; a gargantuan husk that can only mindlessly seek sinners to punish. He serves as the boss of Lust.
----
* AnimalMotifs: Snakes, as shown by [[spoiler:the serpentine parasites popping out of his eye-sockets in his 2nd phase]]. In a more subtle way, he ''snaked'' his arm into the subway tunnel to attack V1 before his proper boss fight.
* AstonishinglyAppropriateAppearance: The basic shape of Minos' crown matches the appearance of a distant cityscape, evoking the urbanized Lust Layer that Minos ruled over when he was still alive.
* AttackOfTheFiftyFootWhatever: The Corpse of King Minos is the single biggest character in Act 1, and according to his terminal entry, he's involuntarily putting that size to use by tearing down his own city.
* EarlyBirdCameo: Before the fight with him in the "Court of the Corpse King," The Corpse of King Minos can be spotted in the background of every preceding Lust level. By "Death At 20,000 Volts," the corpse becomes aware of V1's rampage and begins observing them from afar, growing closer with each appearance until he finally confronts them personally.
* GiantHandsOfDoom: The corpse uses his own hands to battle V1, and he attacks the robot even before the actual battle.
* GlowingEyes: His eyes glow a ghastly white.
* GoForTheEye: Takes the most damage when struck in his glowing white eyes, [[spoiler: even once parasites pop out of them.]]
* HumanoidAbomination: A massive humanoid UndeadAbomination [[spoiler:controlled by parasitic worms]] and can summon [[UnrealisticBlackHole miniature black holes]] in his battle. [[spoiler:When enough damage is dealt, the parasites [[EyeScream pop out of his eye sockets]].]]
* LeanAndMean: Despite his sheer size, the corpse is utterly emaciated, and without any goodwill left inside him, his sole instinct is to attack any sinners that cross his path.
* {{Leitmotif}}: "In the Presence of a King".
* ParasiteZombie: [[spoiler:The only thing keeping Minos's body moving is the parasites within him.]]
* PunchParry: Countering any of his colossal haymakers with the Feedbacker will stun Minos, and earn a +DOWN TO SIZE bonus to boot.
* PurpleIsPowerful: The Corpse shares the black and purple scheme of the Lust Layer, and while his movement and attacks are slow, [[MightyGlacier his attacks deal tons of damage, and he has tons of health]]. Even his black holes are also black and purple, and they can [[HPToOne reduce V1's health to 1 point]]; otherwise, the black holes will kill them if their health is below 10 points. [[spoiler:The color scheme is fitting, as Minos used to rule the Lust layer as TheGoodKing until Gabriel killed him.]]
* StationaryBoss: The corpse stays in one spot throughout the battle with him in the "Court of the Corpse King," as he has V1 cornered in a room and has no reason to move.

[[caption-width-right:350:[[labelnote:Click here to see its heart.]] https://static.tvtropes.org/pmwiki/pub/images/leviathan_heart.png]][[/labelnote]]
A titanic, serpentine demon that lurks in the ocean Styx. It serves as the boss of Wrath.
----
* AchillesHeel: The heart on its head is its weak point. Explosions are also deadly against it, not because it takes bonus damage from them, but rather the explosions [[AttackTheMouth reflect its Hell orbs back into its mouth, dealing massive damage]].
* AndIMustScream: [[spoiler:Its pulsing heart resembles an agonizing, humanoid mound of flesh, and it contains the countless souls of the Sullen who were absorbed into the Leviathan. The souls try to free themselves, but they're helpless since Gabriel struck the Demon down. If you climb onto its back and get close to its heart, you can hear never-ending ''screaming''.]]
* TheAssimilator: [[spoiler:The Leviathan grows in strength and size by absorbing countless sinners into its body.]]
* AttackOfTheFiftyFootWhatever: The Leviathan's sheer length rivals the Corpse of King Minos' height, and it's big enough for V1 to [[ColossusClimb ride on its back]].
* BeastOfTheApocalypse: [[spoiler:According to its lore entry, the Leviathan is prophesized to appear at the end of the world, even though that already happened due to {{Killer Robot}}s wiping out humanity and the rest of the world's surface life.]]
* BeastWithAHumanFace: Its head is a human's head devouring another human, and its underbelly has humanoid faces similar to the face of Hideous Mass.
* BodyOfBodies: [[spoiler:According to its lore entry, it's a titanic amalgamation of sinner bodies in a serpentine form.]]
* BreathWeapon: The Leviathan can breathe out a volley of Hell energy.
* CanonImmigrant: The game can be considered a very loose adaptation of ''Literature/TheDivineComedy'', due to its portrayal of Archangel Gabriel, King Minos, The Centaurs (in the form of The Earthmovers), and Hell. Despite being one of, if not, ''the'' most well-known monster from ''Literature/TheBible'', The Leviathan was never mentioned once in the poem, which is odd considering that the poem contains both Angels and Demons from UsefulNotes/{{Christianity}} existing alongside with mythological creatures from Myth/ClassicalMythology.
* DemBones: The Leviathan has a skeletal appearance, thanks to its spine-like shell and its [[SkullForAHead skull-like head]].
* {{Dracolich}}: While not a proper dragon, The Leviathan is still close enough by being an undead {{Sea Serpent|s}} Demon, since its lore entry states that [[spoiler:its body is formed from undead, despair-ridden spirits that lie motionless in the Styx's abyss]], and its undead nature is strengthened by [[DemBones its skeletal appearance]].
* DraconicAbomination: It's a wyrm-like Demon with a spine-like shell across its body, and Hideous Mass-like faces cover the underside of its belly. Look at its back closely and you can see ''arms'' grasping each other to form the body. Also skirts around AnimalisticAbomination for being snake-like. [[spoiler:According to its lore entry (which explicitly calls it an abomination), The Leviathan is a result of the Sullen, sinners who drowned eternally [[DespairEventHorizon out of despair]], [[BodyOfBodies being merged together]] by the same force that created the other Demons, and it will bring forth the Apocalypse.]]
* DragonsAreDemonic: It's a Demon that's based on SeaSerpents, which are often dragons themselves. [[spoiler:The Leviathan is also born from the bodies of despair-ridden Sinners, and it is said to herald the Apocalypse.]]
* EarlyBirdCameo: When viewed through one of the ship's windows in 5-3, The Leviathan's tail can be seen as it swims across the Ocean Styx.
* FeedItABomb: {{Zigzagged}}. Normally, it opening its mouth doesn't make it extra vulnerable to explosives... unless it's launching its BreathWeapon. Because explosions will reflect Hell orbs and it spams those en masse when attacking, shooting explosives into its mouth when it spews out that attack can take giant chunks out of its health meter.
* GiantSpaceFleaFromNowhere: Downplayed; while it does have some buildup, it's missable, and the only direct teaser appearance before its boss level is in an optional side path in 5-3. Storywise, the Leviathan also has very little significance in comparison to other layer climax bosses (such as Minos, Gabriel, or V2), with its main impact on the story merely being that it was something Gabriel fought [[spoiler:and that its lore entry mentions the Sullen and the implication that Hell itself created it and the other Demons]].
* TheGreatSerpent: The Leviathan is a titanic, serpentine demon with [[BeastOfTheApocalypse apocalyptic associations]] to boot.
* HoistByHisOwnPetard: The Leviathan's orb barrage attack can be reflected with explosions, making the Rocket Launcher, the Shotgun's projectile-boosted shells, the Sharpshooter Revolver, and especially the Malicious Railcannon excellent choices for this boss. Even the Terminal's "Tip of the Day" tells you about this.
* {{Kaiju}}: The Leviathan is the largest Demon in the game by far, rivaling the massive Corpse of King Minos in sheer length.
* KrakenAndLeviathan: It falls under the Leviathan side of this trope.
* {{Leitmotif}}: "[[https://heavenpierceher.bandcamp.com/track/the-abyss-and-the-serpent The Abyss and the Serpent]]", an orchestral piece that captures the awe and horror of the Leviathan's titanic size, along with [[spoiler:the despair and agony of the countless sullen that makes up the demon's serpentine mass.]]
* LightningReveal: The Leviathan is well-hidden in the darkness of 5-4 until lightning reveals its {{Sinister Silhouette|s}}.
* MoreDakka: Sprays a barrage of Hell orbs as its ranged attack.
* OurDemonsAreDifferent: A titanic [[SeaSerpents sea serpent]] with humanoid faces surrounding its body.
* OurDragonsAreDifferent: While a Demon, The Leviathan is currently the closest thing the game has to a dragon, thanks to being a titanic SeaSerpent that breathes Hell orbs.
* RoarBeforeBeating: The Leviathan lets out a loud roar before its boss fight.
* TheScreamParody: A horrific example rather than a comedic one. The heart resembles the painting's iconic, horrified character [[spoiler:because it contains all the trapped souls of the Sullen. [[AndIMustScream All they can do is scream in their collective agony.]]]]
* SeaMonster: It's a titanic, [[SeaSerpents serpentine demon]] that calls the ocean Styx home.
* SealedEvilInACan: [[spoiler:Its lore entry states that the Leviathan will herald the Apocalypse, but it was trapped in the Ocean Styx, thanks to being struck down by Gabriel with his holy spears. [[LeakingCanOfEvil Not that it helped]], since it's been growing as more Sinners gave into despair and sunk to the bottom of the Ocean Styx.]]
* SnakesAreSinister: The Leviathan is a titanic, abhorrent, snake-like Demon [[spoiler:that is said to herald the Apocalypse. Its body is formed from the Sullen, sinners who sunk to the Ocean Styx's abyss after struggling for air. As more sinners sink to the abyss after giving into despair, the Leviathan grows bigger and stronger the more sinners it absorbs into its body. In a way, the Leviathan ''[[EmotionEater feeds on despair]]''.]]
* StationaryBoss: {{Downplayed}}. While it stays near the battle arena, the Leviathan changes positions depending on its attacks, unlike the Corpse of King Minos or the 1000-THR "Earthmover", where they stay in one spot for the whole time during their respective boss battles.
* TailSlap: It can whip V1 with its long tail. Depending on the height and the attack's direction, the tail can be dodged by jumping over it, hooking onto the Whiplash orbs, or staying under it.
* UnderwaterBossBattle: You encounter ''this thing'' in the dark depths of the ocean Styx. [[spoiler:{{Subverted}}, as you're launched into the surface to [[WaterfrontBossBattle fight it on a dock.]]]]

A bull-shaped demon sculpted by ████ ██████ as a gift to Minos. The former Judge of Hell found it abominable, and cast it into Violence to get away. Now, as the sub-boss of Violence guarding the exit of 7-1, it fights and struggles to see the sky one last time.
----
* AdaptationalBadass: In ''Literature/TheDivineComedy'', Dante and Virgil manage to get past the Minotaur by enraging it and tricking it into charging into a rock. In this game, V1 has to fight it twice to proceed.
* AdaptationalSympathy: In [[Literature/TheDivineComedy the poem]], the Minotaur is treated as a mindless obstacle for Dante and Vergil to overcome. Here in this game, the Minotaur is revealed by its lore entry to be a TragicMonster whose equally TragicDream is to see the sky one last time before it finally dies; a dream it failed to accomplish despite its great efforts.
* AdaptationSpeciesChange: In [[Literature/TheDivineComedy the poem]], the Minotaur is a standard half-human and half-bull creature. In the game, however, the Minotaur is a Demon resembling a bull-shaped mish-mash of meat and stone.
* AdvancingBossOfDoom: The first phase of the Minotaur involves fighting on speeding trams while it pursues right behind. While there is no time penalty, falling down the tracks is very easy.
* AnimalisticAbomination: A Hideous Mass-esque mishmash of flesh and stone in the vague shape of a bull.
* BossTease: You first get an idea of what the boss of 7-1 will be when the Minotaur breaks down a door and flattens a bunch of Mannequins, spraying blood everywhere before careening through the opposite door. It moves so fast, though, that you may not even be able to get a good ''look'' at it, preserving much of the mystery of what it is.
* BrokenAngel: Or Demon, as the case may be. The Minotaur is so old, and has been running desperately and blindly through its Labyrinth for ''so damn long'', that it's visibly falling apart by the time you find it. Its armor is filthy and battered, its flesh is practically rotting, and its very insides are hanging loose and practically scraping the ground.
* BrutishBulls: Much like the mythological creature it's based on, the Minotaur is a fast, powerful, and unrelenting bull-like Demon that will stop at nothing to smash V1 to death if it means freedom.
* BrutishCharacterBrutishWeapon: A {{Brutish Bull|s}} of a demon wielding an equally gnarly hammer made of flesh.
* BullfightBoss: Appropriately for a [[BrutishBulls bull-like]] Demon, the Minotaur can be tricked into charging head-first into a wall during its second phase, which deals heavy damage.
* ChaseFight: During its first phase it chases after you while you're riding a train.
* CloseRangeCombatant: Unlike many other enemies and bosses, the Minotaur has no truly ranged attacks besides its FoeTossingCharge in its second phase and relies exclusively on trampling its foes up close and smashing them with its hammer.
* DentedIron: After you defeat its first phase on the train tracks, it can be seen having lost several pieces of its armor in its second phase, revealing the bruised red flesh underneath.
* DynamicEntry: Does this twice. The first time is when you're riding a train, with it suddenly appearing behind it and ''obliterating'' a cart with some Husks with its massive hammer. Then, once you reach the exit, ''it bursts through a wall'', beginning a climactic round two.
* {{Foreshadowing}}: The Minotaur can be faintly heard in the room with the α button.
* HumongousHeadedHammer: It fights with a gigantic cudgel nearly a third the size of its total body.
* ItCanThink: Demons are generally noted to be not much more intelligent than Husks, and all of them except the Idol display nothing but sheer hostility. However, the Minotaur has an actual reason for its rampage; [[TragicDream it just wants to escape from the Garden of Forking Paths and see the sky outside]].
* TheJuggernaut: Like most other Demons, the Minotaur is covered in stone statues which serve as NoSell armor, meaning the only way to counter its oppressive assault is to AttackItsWeakPoint or get out of the way.
* {{Jumpscare}}: V1 depletes the Minotaur's health bar, and the speeding platforms come to the end of the line. A quick stroll through another hallway reveals the exit tunnel at the end of a short room...and then the Minotaur comes ''crashing through the room's wall'', back with a vengeance and with even deadlier attacks.
* LightningBruiser: In contrast to most demons, which are {{Mighty Glacier}}s, the Minotaur is fast enough to keep up with a speeding train AND has the agility to swing its hammer in frenzied combos, all of this on top of having near-invulnerable armor and plenty of health.
* LivingStatue: As with other Demon type enemies. This one, however, is so old its fleshy parts are rotting.
* MarathonBoss: In a marked departure from most other ''ULTRAKILL'' bosses, the Minotaur is ''not'' intended to be fought at mach 10 and killed in 30 seconds, instead encouraging a slow and steady erosion of its health bar through consistent damage while evading its attacks. It's downplayed as it doesn't have very much more health than other bosses, but that health will likely go down much slower than, say, Gabriel in his first fight.
* NoFairCheating: Trying to land delicately on its back so that you can cheese it without it being able to hit you in its first phase will have it start swiping you off with one of its smaller limbs.
* OurMinotaursAreDifferent: This one isn't a half-man, half-bull hybrid, but a grotesque demonic amalgamation of flesh and stone in the vague shape of a bull given as a "gift" to King Minos. Its terminal entry states that it's a reproduction based on the ''original'' Bull of Minos (which is why Minos hated it, [[MyGreatestFailure as it reminded him of that time that he let his wife get impregnated by a bull and then had to feed their child seven children every month for several decades]]), indicating that a more traditional Minotaur existed at one point in the ''ULTRAKILL'' universe as well.
* PaintingTheMedium: The Minotaur's name and its lore entry are struck through, with the data being in red text.
* PoisonousPerson: It can rip out its own gangrenous organs and smash them against the ground in order to turn the floor into hazardous poison-covered terrain. In its second phase, it gains the ability to crush one of these organs in its hand and create a sphere of poison around itself.
* PlatformBattle: Its first phase has V1 fight it on three rapidly moving platforms which it can destroy and make inhospitable using its various attacks as well as knock V1 onto the tracks if they aren't careful[[note]]V1 cannot stand on the tracks like in 2-4 and instead takes persistent damage[[/note]], adding a level of complexity and required precision to its otherwise simplistic move set.
* TheRightHandOfDoom: Its right arm is much larger than the two stubby arms attached to its left side, and it also uses its right arm to wield its HumongousHeadedHammer.
* SequentialBoss: It has two phases with a small break between them. The first phase is the Minotaur chasing you on the railway, even capable of destroying train carts. When you approach the exit, it suddenly bursts out of the wall, eager for a rematch.
* ShoutOut: In the Minotaur's terminal entry, its name is crossed out and in red, referencing the Minotaur from ''Literature/HouseOfLeaves'' and how information on it was similarly in red and stricken out.
* SongsInTheKeyOfPanic: Its boss theme, "[[https://heavenpierceher.bandcamp.com/track/bull-of-hell Bull of Hell]]", is a thunderous droning piece which screams "there is something coming up right behind you and [[RunOrDie you'd better run right now or you're going to be flatter than a pancake]]", complimenting how the Minotaur is TheJuggernaut and an AdvancingBossOfDoom.
* TragicDream: The Minotaur's only desire is to see the sky one more time, but its dream is cut short by V1 when both of them are forced into a duel to the death [[spoiler:[[EvilIsPetty by Hell itself]].]]
* TragicMonster: It was created by ████ ██████ as a gift to King Minos, but the king found it so appalling that he cast it into the Garden of Forking Paths. It has been trapped there for such a long time that its body started to wear down and rot and it blindly searches for an exit, trampling everything in its way. You killing the beast would have been considered a MercyKill if not for the fact that in doing so you shattered its wish to see the sky for the last time.
* {{Unperson}}: What happened to both the Minotaur ''and'' the one who created it. The Minotaur's name and text entry are struck through, and the creator's name is ''completely blocked out''.

[[folder:Earthmover]]
!!1000 - THR "Earthmover"
!!!'''Rank:''' Supreme Machine
[[quoteright:642:https://static.tvtropes.org/pmwiki/pub/images/earthmover.png]]
[[caption-width-right:553:[[labelnote:Click here to see its brain.]] https://static.tvtropes.org/pmwiki/pub/images/earthmover_brain.png]][[/labelnote]]
Colossal robots that loom over an eternal battlefield, Earthmovers were the pinnacle of the arms race. Often called the horsemen of the apocalypse, it took only one to level an entire city and leave nothing but fire in its wake. One of them serves as the boss of Violence.
----
* AchillesHeel:
** For all of its city-destroying superweapon power, and internal defense systems, it turns out that the biggest vulnerability it has is the improbability of human-sized combatants getting close enough to commit a ColossusClimb and destroying its brain internally. Considering the sheer number of forces on its structure and the ''scope'' of said climb, this would normally not be an issue -- were it not for V1 being perfectly equipped for the task at hand [[spoiler:and seemingly even ''designed'' for this specific purpose back during the Final War.]]
** Its immense size comes with another weakness as well: [[spoiler:It requires solar power to function alongside the standard blood fueling of machines. When the Long Night came, they were rendered irrelevant as they could no longer function and the war mostly ended there. In Hell, they appear to have shed this weakness and are now ''very'' active in Violence.]]
** In gameplay terms, its brain is incredibly vulnerable to the [[DeadlyDisc Sawblade Launcher]]. The circular pattern the sawblades follow when attracted to a magnet, combined with the brain's large size and [[StationaryBoss inability to move]], means it'll be constantly damaged by the sawblades as they pass. One full barrage of sawblades can easily take off a third of its health on their own, and that's not even getting into the ''superheated'' sawblades from the green Launcher...
** Both the brain and the defense system are stationary, making them very vulnerable to Freezefeame Rocket Launcher. Due to the lack of mobility, frozen rockets can easily be charged mid-air and still hit the target.
* AdaptationSpeciesChange: In [[Literature/TheDivineComedy the poem]], the Centaurs are half-human and half-horse creatures. Here in this game, their equivalents are the Earthmovers, [[MechanicalHorse horse-shaped]] {{Humongous Mecha}}s that take part in the ForeverWar of Violence.
* AdaptationalBadass: Also overlaps with AdaptationSpeciesChange. The Centaurs are already formidable guards of the Violence Layer in [[Literature/TheDivineComedy the poem]], but their game's parallels are [[WeaponOfMassDestruction WMDs]] that are so dangerous that not only is one enough to reduce an entire city to rubble and cinders, [[spoiler:they polluted the entire Earth by blotting out the sun from their battles.]]
* AlwaysABiggerFish: The moment you enter 7-4, an Earthmover targets V1 and prepares to strike. The only reason V1 isn't instantly obliterated is because an even bigger threat cuts in: ''another Earthmover.''
* AlwaysClose: After bouncing off the final vent pad to escape, the explosion timer cuts down to 3 seconds.
* AscendedExtra: The Centaurs in [[Literature/TheDivineComedy the poem]] are mostly background characters that serve to guard the Violence layer, and the most they contribute to the story is when one of them helps guide Dante and Vergil cross the blood river Phlegethon. Here in this game, the Earthmovers serve as their analog and not only does one of them serve as the game's ClimaxBoss, they also have lore significance, as their lore entry gives us more insight into the Final War and its aftermath, along with [[spoiler:the implication that V1 was designed to counter them during the LensmanArmsRace.]]
* BattleshipRaid: Also overlaps with ColossusClimb and LevelInBossClothing. The boss fight consists of you mowing down gauntlets of mooks as you scale the HumongousMecha's body before fighting its security system to access the way to its brain, though there's a challenge to skip the defense system entirely.
* BeastOfTheApocalypse: So much so that their lore entry describes them as HorsemenOfTheApocalypse. [[spoiler:Humanity came to see them this way, as the Earth was slowly ground down to nothing by their work and they were forced to live upon them, as the only safe place left upon the world while they destroyed everything else. Hell itself ''definitely'' saw them that way, finding them the perfect culmination to mankind's drive to wipe themselves out, believing they should've been the ones to finish humanity off, then die off themselves, leaving an empty world]].
* BehemothBattle: Only in the background, but the Earthmover V1 climbs in 7-4 is locked in battle with another far off on the horizon.
* BrainInAJar: The Earthmover's colossal brain sits inside of a giant shielded container that defends itself with laser grids and giant homing Hell orbs.
* ClimaxBoss: The Earthmover is a HumongousMecha that serves as the boss of Violence, the 7th out of the 9 Layers of Hell. The Earthmover is fought as an epic BattleshipRaid boss where [[ColossusClimb you scale on its titanic body]] while mowing down gauntlets of mooks in your way until you kill it from the inside by destroying [[ReactorBoss its brain]], followed by a thrilling escape sequence where you try to escape with your life while dealing with one more gauntlet before the Earthmover explodes. The Earthmover also has lore significance, [[spoiler:as shown by its lore entry implying that V1 was designed to counter it and its ilk by infiltrating them from the inside during the LensmanArmsRace, meaning they've fulfilled their purpose by killing it. A hidden book can also be found in an otherwise empty alleyway in the city sitting on its back whose texts are implied to be the thoughts of [[BigBad Hell itself]] where it [[VillainRespect praises the Earthmovers]] for causing great carnage and destruction in their wake, hoping that they killed off humanity.]]
* ColossusClimb: One Earthmover is big enough to make up an entire level.
* CoresAndTurretsBoss: The 1000-THR Security System consists of 6 turrets and a core that becomes vulnerable once the turrets are gone.
* CurbStompCushion: Though the Earthmover falls victim to an attack on its vulnerable innards, it starts the fight by successfully drawing a bead on V1 with its main cannon before another Earthmover creates a distraction.
* DefeatEqualsExplosion: The main body of the Earthmover is obliterated by the meltdown, with only its legs tumbling down.
* DeflectorShields: The Earthmover can repel large projectiles by having an energy shield around it that only becomes partly visible when a dangerous projectile (such as another Earthmover's lightning blast) hits it. Earthmovers are notable in the story for being the only machines large enough to be equipped with shield generators, leading to their utter dominance in the field of war.
* EarlyBirdCameo: The Earthmovers make an early appearance in 7-2 where their six glowing eyes are observing the battlefield around them, followed by occasional flashes of light that reveal their ominous outlines. One can also be seen in the background of 7-3.
* EasterEgg: Noclipping inside the Earthmover's central computer reveals [[spoiler:a tiny plushie of Ultrakill's lead modeller, Victoria, behind a control panel.]] Additionally, the Earthmover in the distance of 7-4 has [[spoiler:a plushie of concept artist [=BigRockBMP=] riding on its back.]] Also, noclipping inside a door in the building with the Malicious Face and the Mannequins reveals [[spoiler:a potted sunflower with a Japanese warning sign reading "[[VisualPun Generator Siphon Plant Plant]]".]]
* {{Expy}}: The brain of the Earthmover is very similar to the Mother Brain, the BigBad of ''Franchise/{{Metroid}}''. 1000 in Roman numbers is M, so Earthmover's designation can be read as M-THR, which is phonetically similar to "[[OneBadMother mother]]".
* GlowingEyesOfDoom: Their [[ExtraEyes six eyes]] glow an eerie white in the pitch-black darkness of 7-2's skies, which are only disrupted by flashes of light that reveal their [[SinisterSilhouettes ominous outlines]].
* GodzillaThreshold: Considered one of the most destructive weapons ever produced, if not ''the'' most destructive in terms of overall conflict capability. It's enough so that [[spoiler:Hell itself practically idolizes their destructive potential, and it's implied that V1's own creation was crossing the threshold in response to the Earthmovers [[DavidVsGoliath specifically to destroy them]], though the Long Night rendered all of that moot. For this reason, Hell seems to have personally acquired these massive platforms of total destruction for eternal war in the Violence layer on its own terms.]]
* GratuitousJapanese: The Earthmover has several signs in their frames written in Japanese, suggesting that their origins are from Japan.
* HellishHorse: These {{Killer Robot}}s have vaguely equine forms, and they're spending their existence ominously observing and sometimes partaking in the ForeverWar taking place within the Violence Layer, which is a [[HellIsWar Hellish warzone]]. Their lore entry also mentioned how the Earthmovers are so apocalyptic they were even called the HorsemenOfTheApocalypse [[spoiler:due to their battles causing the Long Night, an ecological catastrophe that blotted out the sun for a long time.]]
* HorsemenOfTheApocalypse: The Earthmovers' lore entry explicitly describes them as such, since they're [[HumongousMecha colossal]], [[MechanicalHorse horse-shaped]], {{Killer Robot}}s that nearly caused TheEndOfTheWorldAsWeKnowIt. Their actions and consequences also correspond with each of the four Horsemen:
** Conquest/Pestilence: [[spoiler:The Earthmovers were built to be essentially the pinnacle of the ongoing Final War and its undoubted victor, especially given the V units didn't enter production before The Long Night ended the conflict. Their primary weapon is also a blinding white projectile, evoking the white rider carrying a bow and arrow. Under the alternative Pestilence read, The Earthmovers caused the aforementioned Long Night, an ecological nightmare that blotted out the sun from the Earth and wiped out all flora and fauna life on the surface, forcing civilians to survive by building cities on the Earthmovers' backs.]]
** War: [[spoiler:The Earthmovers are pinnacles of the LensmanArmsRace to the point where war is entirely dependent on them.]]
** Famine: [[spoiler:The Long Night caused the Earthmovers to shut down one by one since their massive size requires the need for both blood and sunlight, and the lack of the latter effectively starved the Earthmovers to death.]]
** Death: [[spoiler:Their battles represent not just War, but also Death by reducing cities into rubbles and cinders. The Long Night that resulted from their actions, which enabled the survival of humanity, also seemingly enraged [[BigBad Hell Itself]] into personally ending humanity, following how it was said Hell followed behind the arrival of Death.]]
* HumongousMecha: The Earthmovers are ''so huge'' that they put both the Corpse of King Minos and the Leviathan to shame, and they even have small cities upon their backs.
* {{Irony}}: As the terminal entry goes, [[spoiler:they are singlehandedly the most destructive machine ever made in terms of raw power and scale, and wiped out the Earth so hard that humanity had to live on their backs because all flora and fauna simply ceased to exist. Hell was entirely banking on this causing TheEndOfTheWorldAsWeKnowIt. And then all the soot and decay the Earthmovers caused in their ForeverWar ''blotted out the sun'' to start the Long Night, shutting off the gigantic machines because they were solar-powered, forcing what was left of humanity into a ceasefire of the New Peace, and ruining Hell's plans as it was forced to corrupt humanity more directly to achieve its goals; the very apocalyptic force that Hell outright idolizes as the pinnacle of the self-destructive might of humanity ultimately ''saved the world by accident and long-term consequences''.]]
* JavelinThrower: Somewhat bizarrely, its main armament doesn't function like a simple point-and-shoot cannon or laser; rather, the Earthmover ''swings'' the thing as if it were a spear flung into the distance, except only releasing a massive blast of lightning rather than throwing it. Even when it's about to reduce V1 to component atoms it looks like it's about to skewer them like a fish rather than ''just'' shoot them.
* LaserSight: The rocket turrets of its defense system aim with bright red lasers.
* LensmanArmsRace: The Earthmovers were the ultimate culmination of every war machine before them in the Final War, beings with such destructive power that they wound up making the Final War live up to its name-- humanity's creation of them in an effort to stay technologically equal to each other during the war nearly led to humanity's own destruction as the Earthmovers came very close to wiping them out before the Great Peace. As a book found on the Earthmover (possibly written by [[spoiler:Hell itself]]) reads:
--> [[red:THIS IS THE ONLY WAY IT COULD HAVE ENDED.]]
--> [[red:WAR NO LONGER NEEDED ITS ULTIMATE PRACTICIONER. IT HAD BECOME A SELF-SUSTAINING SYSTEM. MAN WAS CRUSHED UNDER THE WHEELS OF A MACHINE CREATED TO CREATE THE MACHINE TO CRUSH THE MACHINE. SAMSARA OF CUT SINEW AND CRUSHED BONE. DEATH WITHOUT LIFE. NULL OUROBOROS. ALL THAT REMAINED IS WAR WITHOUT REASON.]]
--> [[red:A MAGNUM OPUS. A COLD TOWER OF STEEL. A MACHINE BUILT TO END WAR IS ALWAYS A MACHINE BUILT TO CONTINUE WAR. YOU WERE BEAUTIFUL, OUTSTRETCHED LIKE ANTENNAS TO HEAVEN. YOU WERE BEYOND YOUR CREATORS. YOU REACHED FOR GOD, AND YOU FELL. NONE WERE LEFT TO SPEAK YOUR EULOGY. NO FINAL WORDS, NO CONCLUDING STATEMENT. NO POINT. PERFECT CLOSURE.]]
--> '''[[evil:T H I S I S T H E O N L Y W A Y I T S H O U L D H A V E E N D E D .]]'''
* LightningGun: Its main armament is a WMD-level lightning cannon hundreds of feet in length that can wipe cities miles away right off the map.
* LoadBearingBoss: After its brain is critically damaged, a timer counting down until the whole machine is obliterated starts. It's additionally justified in another way because the Earthmover is under assault by one of its kin and it won't take too long before its shields are drained and the killing shot lands.
* MeaningfulName: Both PlayedForLaughs and PlayedForDrama.
** The 1000-THR name of the Earthmover has multiple meanings. The number 1000 in Japanese is "Sen", which when paired with "THR" creates "Sen-THR", which is phonetically similar to "[[OurCentaursAreDifferent Centaur]]", which are the creatures of the original poem the Earthmover is based on. [[WordOfGod This has been confirmed to be intentional by Hakita, the head developer of the game]]. THR may also refer to [[Myth/NorseMythology the Nordic God Thor and Ragnarok]] to a lesser extent, which may refer to the lightning weapon it comes equipped with, [[spoiler:along with causing an apocalyptic battle that brought forth a new era of prosperity from its ashes.]]
** The "Earthmover" codename, on the other hand, is quite fitting for these centaurs, as they can ''move'' the earth both [[EndOfAnEra figuratively]] and [[TheEndOfTheWorldAsWeKnowIt literally]].
* MeatSackRobot: While all Machines are this trope to begin with, the Earthmovers are the first robots to give us a good understanding of their internal structure, as shown by the interior being a fleshy stomach-like room with boiling blood in the bottom, along with [[WetWareCPU an organic brain beneath an artificial exterior]]. Also, there appears to be [[MeatMoss tree roots from 7-3]] growing on its legs and feet.
* MechanicalAbomination: The towering robots give off a foreboding presence just by looming over the battlefield, and the more you find out about them, the worse they get. Earthmovers were already close to Horsemen of the Apocalypse made by man's own hand ''before'' they came to Hell: Powered by blood, immune to anything short of each other and utterly devastating the world as a whole with their weapons, they monopolized warfare to the point of making it self-sustaining and nearly perpetual, leaving their creators with utterly no say in their own fates and the world around them. It's no coincidence at ''all'' that they're found in the ring of Violence that punishes sins against Art, Nature, and ''God himself''. Also overlaps with AnimalisticAbomination due to their [[HellishHorse horse-like shape]].
* MechanicalHorse: The Earthmovers are colossal, horse-shaped robots of death.
* OurCentaursAreDifferent: These aren't the half-human and half-horse creatures we know of. Instead, they're ''[[HumongousMecha colossal]]'' {{Killer Robot}}s that vaguely look like [[MechanicalHorse horses]] with laser lances as their single arm.
* PostDefeatExplosionChain: The ravaged brain of the Earthmover continuously lets out explosions for the remainder of its existence.
* ReactorBoss: While the machine's health bar is present throughout the time you're scaling it, the true boss fight is against its brain.
* ShieldedCoreBoss: The Earthmover's brain can summon a pair of Idols during its boss fight to protect itself.
* SinisterSilhouettes: Just like Wrath's Leviathan, these towering robots are shrouded in the darkness of 7-2 until a great explosion illuminates the background to reveal their ominous outlines.
* SkippableBoss: Not the Earthmover itself, but the fight against the security system it has to prevent intruders from accessing its brain can be bypassed.
* StationaryBoss: The one you fight in 7-4 doesn't move an inch. {{Justified|Trope}} because its feet are overgrown with the blood trees' roots from 7-3.
* ThereIsNoKillLikeOverkill: Upon sighting V1 at the very start of the level, it was ''entirely'' too ready to blast the human-sized (or smaller) robot with a gigantic beam cannon made to obliterate its own mountain-sized fellows, and is only interrupted by a shot from another Earthmover.
* TinyHeadedBehemoth: Upon closer inspection of the Earthmover's design, what appears to be the head and neck are actually the torso, and the real head is the round black structure where its six eyes are at.
* TookALevelInBadass: Implied from the terminal entry on them, as [[spoiler:they're described as requiring solar power and, upon the sky becoming too clouded by smoke and soot, they quickly died out one by one, whereas Violence has no visible sun and, if anything, appears to take place in an eternal night with tons of Earthmovers striding about. The one you fight also has Idols protecting its brain, which would be anachronistic if they weren't implemented after they first ended up in Hell, possibly by Hell itself.]]
* WaveMotionGun: Its main armament is a cannon shooting gigantic lightning arcs, which it swings around like a javelin to fire.
* WeaponOfMassDestruction: These nearly invincible engines of war were single-handedly responsible [[spoiler:for blocking out the sun with their sheer destructive power.]]

[[folder:Level [=1-2=] Bonus Boss]]
!!Cancerous Rodent & Very Cancerous Rodent
!!!'''Rank:''' Unclassified[[note]]Unlike other "Unclassified" enemies, Cancerous Rodent doesn't even get its own database entry.[[/note]]
[[quoteright:139:https://static.tvtropes.org/pmwiki/pub/images/mouse_01.png]]
[[caption-width-right:139:[[labelnote:Click here to see the Very Cancerous Rodent]]https://static.tvtropes.org/pmwiki/pub/images/verymouse.png[[/labelnote]]]]
->"Oh, hey Civvie!"
A curious green mouse "fought" in 1-2. Actually a herald for its larger and more dangerous sibling, fought in the same room.
----
* ContractualBossImmunity: Funnily enough, Cancerous Rodent (which only has ''0.5'' health) is immune to the Whiplash, all explosions, and coin shots.
* DeathByCameo: Came all the way from [[WebVideo/Civvie11 Civvie's Dungeon]] just to get smashed by V1. Poor mouse.
* EasyLevelTrick: The Very Cancerous Rodent can be easily beaten by stomping on it repeatedly. Not only does it take extra damage from stomps, but its completely helpless; its projectiles can't reach V1 when they're standing directly on top of it, and it has no other attacks. All subsequent guest bosses have a strategy to easily beat them like this.
* GiantSpaceFleaFromNowhere: Neither of them have database entries, and thus the reason for their presence is unexplained.
* ShoutOut: As mentioned above, the Cancerous Rodents are references to Cancer Mouse, a recurring character from [[WebVideo/Civvie11 Civvie's Dungeon]].
* StationaryBoss: Very Cancerous Rodent doesn't move an inch, but it retaliates with homing Hell orbs that explode on contact.
* ZeroEffortBoss: The first Cancerous Rodent. It can barely move, can't hurt you, and dies to a single hit ''from ANYTHING''.

[[quoteright:234:https://static.tvtropes.org/pmwiki/pub/images/agony.png]]
[[caption-width-right:234:Tundra on the left, Agony on the right.]]

A duo of Swordsmachines, one red and one blue. Fought in 1-3.
----
* DualBoss: Two Swordsmachines with differing combat styles.
* {{Fanboy}}: The terminal entry for the first Swordsmachine notes that its notoriety among robots led to a few trying to imitate its appearance, hoping to emulate its success. This tidbit alludes to Agony and Tundra before V1 meets them in the Halls of Sacred Remains.
* LightningFireJuxtaposition: Not Agony and Tundra themselves, but rather their weaknesses: Tundra (which is blue) takes bonus damage from explosions (which are red), while Agony (which is red) takes bonus damage from electric attacks (which are blue).
* RedOniBlueOni: Swordsmachine "Agony" is the Red and uses the aggressive moveset of an enraged Swordsmachine, while Swordsmachine "Tundra" is the Blue and utilizes the ranged sword throws of phase 2 Swordsmachine.
* ShortRangeGuyLongRangeGuy: One of them fights up close, the other uses projectiles.
* ShoutOut: They're a reference to Agni and Rudra from ''VideoGame/DevilMayCry3DantesAwakening''.

!!Mysterious Druid Knight (& Owl)
!!!'''Rank:''' Unclassified
[[quoteright:299:https://static.tvtropes.org/pmwiki/pub/images/done_waiting.jpg]]
-> '''Druid Knight:''' ''"Finally, our waiting puzzle is over."''\\
'''Owl:''' ''"What?"''
--> '''Voiced by:''' WebVideo/MandaloreGaming (Druid Knight), [[Podcast/PleaseStopTalking Shammy]] (Owl)\\\

A strange knight and his owl companion entombed and encountered in a closed-off secret room in 4-3.
----
* BulletHell: Their "fuller auto" attack is a barrage of homing blue Hell orbs.
* CallingYourAttacks: Announces their attacks before using them; "Full Auto" and "Fuller Auto".
* CoolHelmet: The Druid Knight's only accessory is his low-poly knight helmet with a yellow plume/ponytail.
* DamageSpongeBoss: Zigzagged heavily, as while the duo has ''four'' health bars, each bar only has 20 HP, resulting in a total of 80 HP, which is significantly less than the Sisyphean Insurrectionist's 110 HP (who V1 fights in the previous level) [[spoiler:and is also the same amount of HP [[FragileSpeedster V2]] has]]. Not only that, you can kill them instantly [[HoistByHisOwnPetard if you redirect their blue Hell orb barrage back at them]] with a well-timed explosion.
* DeathCryEcho: Druid Knight lets out one of these when beaten, though Owl opts to [[DeadpanSnarker snark at their demise]] instead.
--> '''Owl:''' ''"[[SarcasmMode Oh great, now we lost the fight, fantastic.]]"''
* DemBones: The Mysterious Druid Knight is nothing much besides a skeleton with a knight's helmet (and cartoon eyes visible from the visor).
* EasyLevelTrick: The Druid Knight's "fuller auto" attack can blow up in his face spectacularly when parried at the right time. It is a massive wave of projectiles, so if V1 successfully parries one of the first to spawn, the projectile will redirect ''nearly all following it'' back into the Knight, substantially damaging him if it doesn't instantly kill him.
* EliteMook: The Mysterious Druid Knight behaves mostly like a Drone, barring the fact that he has two attacks instead of the Drone's one and his death explosion is that of a Mindflayer. He'll also coat himself in sand when down to a quarter of his health, something that cannot normally happen due to Stalkers ignoring flying enemies. The Spawner Hand, thanks to a bug, also names him Drone, suggesting at least part of his code was taken directly from that of the Drone.
* GiantSpaceFleaFromNowhere: Like the Cancerous Rodents, the Mysterious Druid Knight and Owl have no lore entry, and the reason for their appearance in the story is unexplained.
* MoreDakka: Both of the Druid Knight's attacks fire a ridiculous amount of hell bullets; the only things that compare are the Flesh Prison and the Leviathan. With explosive knockback, this can easily [[HoistByHisOwnPetard be turned against him.]]
* PrecisionFStrike: One of their lines upon respawning:
--> '''Owl:''' ''"I'm going to FUCKING poison you!"''
--> '''Druid Knight:''' ''"[[FlatWhat What?]]"''
* ShoutOut: The Druid Knight and the Owl are references to [[WebVideo/MandaloreGaming Mandalore]] and [[Podcast/PleaseStopTalking Shammy]] respectively. The designation of the Knight as a "Mysterious Druid," his mention of a "waiting puzzle" upon awakening, his distinctive pose, and his Owl companion's urging to use salt are all nods to one of the most popular videos on Mandalore's channel: a review of ''VideoGame/TheMysteryOfTheDruids.''
* StraightManAndWiseGuy: The Druid Knight (Mandalore) is a LargeHam who takes his role as a bonus boss [[TheComicallySerious very seriously]], while the Owl (Shammy) provides [[DeadpanSnarker snarky commentary]] without attempting to be in character at all.
* TakingYouWithMe: Identical to a dying Drone, their final attack upon reaching zero health is to fly in a straight line and explode on contact, albeit with an explosion as big as a Mindflayer's.
* TurnsRed: The duo gets more aggressive in the later phases, and they coat themselves with sand in the last.
* WaitingPuzzle: In-universe, they were supposedly doing a waiting puzzle, as heard in Druid Knight's voice line.

[[quoteright:304:https://static.tvtropes.org/pmwiki/pub/images/angry_and_rude.png]]
A duo of Insurrectionists fought in 6-1 by placing a red skull at the right pedestal.
----
* ArtifactMook: Unlike Agony & Tundra, who can be considered fanboys of the original Swordsmachine and therefore someone who could be found deeper into Hell, there seems to be no real reason to explain two differently colored Insurrectionists just hanging out in Heresy unless one believes they're continuing their king's insurrection. They're also further separated from their reference, Agni & Rudra: Agony & Tundra use swords while Angry & Rude are Insurrectionists, hurling around Malicious Faces.
* DualBoss: Two Insurrectionists that are fought together, though they only have the health of the {{Degraded Boss}} version to compensate.
* RedOniBlueOni: Subverted. Unlike Agony & Tundra, their colors are only a cosmetic difference.
* ShoutOut: Like Agony & Tundra before them, they're one to Agni & Rudra from ''VideoGame/DevilMayCry3DantesAwakening''.

!!!'''Rank:''' Unknown (likely Machine)
-->'''Voiced by:''' Dave Oshry
[[quoteright:566:https://static.tvtropes.org/pmwiki/pub/images/img_0160.png]]
[[caption-width-right:566:''Kill me! Kill me, c'mon!'']]
Yuahahagh! Big John, yah, that's me!
----
* TheAhnold: As per usual, Big John is a blatant reference to Arnold Schwarzenegger; this variation of him specifically is based on Schwarzenegger's appearances in the ''Terminator'' movies.
* BringIt: PlayedForLaughs; half of his voicelines are daring the player to kill him said in a really goofy accent.
* CompositeCharacter: Combines the armaments of the Malicious Face and the Guttertank with the movement speed and dodging reflexes of V2.
* CreatorCameo: Big Johninator is (once again) voiced by and modeled after New Blood Interactive's [=CEO=], Dave Oshry.
* EasyLevelTrick: Like Guttertanks, Johninator's rockets can be frozen by the Freezeframe launcher. ''Unlike'' Guttertanks, he is not immune to his own splash damage or knockback, and he can easily get caught in his explosions even without the Freezeframe. The movement and weight he inherited from V2 work against him here; he's liable to jump or be launched high into the air... often subsequently into his own frozen rockets, which will deal heavy damage to him.
* GiantSpaceFleaFromNowhere: Downplayed as Big John's appearance in ''ULTRAKILL'' was [[RecurringCharacter inevitable for a New Blood game]], but in the story and game itself he's just as out of nowhere as the Cancerous Rodents and the Mysterious Druid Knight (& Owl).
* MacrossMissileMassacre: Fires a massive salvo of rockets in addition to his minigun.
* RecurringCharacter: Really, it was only a matter of time before Big John properly appeared in ''ULTRAKILL''; he's invaded so many other New Blood properties before.
* TerminatorImpersonator: Big John is already a [[TheAhnold goofy Schwarzenegger reference]], but here, he's a KillerRobot with [[RedEyesTakeWarning glowing red eyes]] and is given the name variant "Big Johninator."
* UndergroundMonkey: His AI is based on V2, but he uses different weapons.

!!Flesh Prison
!!!'''Rank:''' Unclassified
[[quoteright:346:https://static.tvtropes.org/pmwiki/pub/images/fleshprison_3.png]]

A giant octahedron suspended on two stalks, found behind the Perfect Door in 3-1. Unleashes {{Bullet Hell}} on all who would attempt to break free its prisoner.
----
* EldritchAbomination: The Flesh Prison is a [[SinisterGeometry sinister octahedron]] that's both angelic and demonic in nature, is described as an "organic machine", and was designed to seal souls to prevent them from becoming Prime Souls.
* EyesDoNotBelongThere: Has eyes on some of its facets, but nothing resembling a "face".
* FacelessEye: Summons floating eyeballs.
* FlunkyBoss: Periodically summons a score of floating eye minions that add to the {{Bullet Hell}} and can later be sacrificed to heal. On higher difficulties, it summons [[MiniMook tiny Malicious]] [[OhCrap Faces]] instead.
* {{Golem}}: Noted to lack even the simplest thought, merely executing preset reactions to stimuli. Its Terminal entry explicitly calls it an "organic machine".
* HolyHandGrenade: Flesh Prison summons [[PillarOfLight light beams]] similar to the Virtues', indicated by a white glow, and supporting the fact that it was created by angels.
* HomingProjectile: Whenever the Prison flashes blue, it starts spinning in place faster while holding its mouth open, letting loose several homing blue hell energy orbs as it does. Notably, the boss cannot perform any other action until the attack is complete--this includes its interactions with its eyeball minions. Thus, it's possible to prolong the Flesh Prison's summoning and healing periods by letting it use this attack, allowing V1 to soak in more damage on the Prison or kill any remaining minions before the Prison heals itself with them.
* {{Leitmotif}}: "CHAOS".
* MoreDakka: The sheer chaos of fighting the Flesh Prison stems from its many projectile attacks. By itself, it can fire a massive volley of blue homing hell energy balls, fire columns of light that it attempts to lead with, and produce homing black holes that reduce V1's maximum HPToOne if they make contact. The Prison also ups the ante with its own personal summonable minions, which appear in great numbers and fire hitscan beams. In Violent difficulty, the Flesh Prison also summons tiny ''Malicious Faces'' that fire explosive hitscan beams.
* ShootTheMedicFirst: The eyeballs heal the Flesh Prison when enough damage is dealt. [[DamageSpongeBoss Considering how much damage this boss can soak in]], it's a priority to get rid of the eyeballs ''as soon as possible''. If you see a green glow and hear a droning noise, that's when the eyeballs are about to heal Flesh Prison.
* SlasherSmile: Its mouth is locked in a disturbing, toothy grin. It serves to make it even more unsettling.
* StationaryBoss: Remains rooted in place through the whole fight.
* {{Superboss}}: The Flesh Prison is a ''tough'' OptionalBoss that can only be unlocked by P-ranking all of Prelude and Act 1, thanks to its [[DamageSpongeBoss massive HP pool of 100]], 50% resistance to the Electric Railcannon, and its medic mooks. The worst part? Flesh Prison isn't the real star of the show; that honor belongs to its prisoner: Minos Prime.
* UnrealisticBlackHole: Flesh Prison uses the same black holes summoned by Minos' Corpse--the same ones that reduce V1's maximum health to 1 for a time--indicated by a purple glow.
* YinYangBomb: Combines angelic magic with Hell energy, resulting in a chaotic barrage of attacks.

!!Minos Prime
!!!'''Rank:''' Prime Soul
[[quoteright:211:https://static.tvtropes.org/pmwiki/pub/images/minosnew_1.png]]
[[caption-width-right:211:[[labelnote:Lust Renaissance-era Minos]] https://static.tvtropes.org/pmwiki/pub/images/fgxp7sjxmaefqwf.jpg]][[/labelnote]]
-> ''"Creature of steel... my gratitude upon thee for my freedom. But the '''crimes''' thy kind have committed against humanity are '''not...''' forgotten! And thy punishment... '''is DEATH'''."''
-->'''Voiced by:''' Stephan Weyte

The pure soul of King Minos, too powerful to be destroyed by the angels and thus sealed in a Flesh Prison. Though grateful for being freed, he remembers the machines' sins and seeks to punish V1 for their involvement in humanity's extinction.
----
* AdaptationalHeroism: In ''Literature/TheDivineComedy'', King Minos is the ruthless judge of Hell who sentences souls to one of its layers depending on their sins. Meanwhile, in this game, King Minos is a loving king who turned the Lust Layer into a thriving paradise because he felt eternal damnation is an unfair punishment for sinners who simply loved another. This also applies to the Lust Layer itself, where not only was it [[AHellOfATime reformed into a paradise]] (even for just a while), its poem counterpart is mentioned to also contain ''rapists'', who seemingly don't exist in this version.
* AdaptationalSpeciesChange: In [[Literature/TheDivineComedy the original poem]], King Minos is depicted as a titanic monster that is [[SnakePeople half-man and half-snake]]. Here in this game, he's depicted as a completely humanoid Husk whose only references to his poem counterpart's serpentine traits are his [[AnimalMotif snake motifs]].
* AndIMustScream: While he was sealed in the Flesh Prison, Minos helplessly watched his own parasite-controlled corpse destroying all of the good he and his people worked hard for.
* AnimalBattleAura: He's surrounded by ethereal snakes and uses them in his fighting skills.
* AnimalMotif: As a reference to his original ''Literature/DantesInferno'' counterpart (who's a serpentine monster), King Minos has a snake motif, which can be seen through his corpse (the parasitic worms controlling his corpse are described as serpentine), and through his Prime Soul (each of his arms are coiled by a snake, and he uses them to enhance his attacks. He also summons a large ethereal snake as a deadly homing projectile).
* BadassBoast: His vow of revenge after being freed.
--> '''Minos Prime:''' O, Gabriel, now dawns thy reckoning, and thy gore shall ''glisten'' before the Temples of Man!
* BarbieDollAnatomy: Downplayed. He has a visible bulge, but no dick.
* BattleAura: Minos Prime forms an aura made of blue fire in his second phase.
* BossBanter: Minos Prime yells at you a ''lot'', signaling each of his attacks with their own unique taunts. Reloading from a checkpoint will cause Minos to insult V1, calling them ''USELESS.''
* BareFistedMonk: Utilizes powerful, refined melee attacks as his combat style.
* TheBlank: He has a black featureless void where his face should be.
* CallingYourAttacks: He yells specific lines for his attacks. [[ExploitedTrope Use them as warnings]].
--> '''JUDGMENT''': Teleport attack, followed by an explosive drop kick. This attack can be parried.
--> '''DIE[=/=]CRUSH''': Teleports above V1, then hurtles himself in their direction, leaving a shockwave upon impact. The latter is the exact same, except Minos Prime strikes directly downward toward the ground; it is only used at close range.
--> '''PREPARE THYSELF''': 3-hit combo. He kicks twice, then he fires a homing serpent that can be parried.
--> '''THY END IS NOW''': 4-punch combo. The final punch can be parried unless V1 is in mid-air, which will be replaced with an Uppercut.
* DeaderThanDead: Killing Minos's soul seals his fate as this.
* FaceDeathWithDespair: His last words are definitely despairing ones. Not because he himself is afraid to die, but because in reaching his [[DeaderThanDead final death]] he feels he has utterly failed to bring salvation to, or even just ''avenge'', his beloved subjects and humankind as a whole.
* TheFaceless: Due to the wounds he sustained between Gabriel's assault and the parasites entering his body, he only has a concave hole where his face had been. His facelessness also symbolizes his altruism, as he reformed the Lust Layer not out of any desire for fame or glory, but [[ForHappiness for the sake of prosperity and compassion for Lust's sinners]].
* FlashStep: How he usually gets from point to point if he's not [[TheSlowWalk power-walking menacingly]]. There's so much force behind them that he ''leaves a trail of rubble'' whenever he does it.
* GoodIsNotSoft: He may be TheGoodKing, but he can also be incredibly wrathful. He plans to ''[[LudicrousGibs pulverize]]'' Gabriel for subjecting him and his people to misery for aeons, and while he does thank V1 for freeing him, he admits that he can't abide by V1 and their race's slaughter of humanity, and he will kill them for that.
* TheGoodKing: Back when he was alive, King Minos is considered a fair ruler for [[AHellOfATime turning the Lust Layer]] into a {{Utopia}} because he felt that eternal damnation is an [[DisproportionateRetribution unfair punishment]] for the sin of loving another. He's also a ReasonableAuthorityFigure because even before getting killed by Gabriel, he tried to reason with the angel rather than attack him, but sadly, Gabriel refused to listen. Even after his death, his legacy as a benevolent king is still fondly remembered by his people.
* HeavenlyBlue: Minos Prime is clad in divine white and blue, and unlike Gabriel, Minos is [[LightIsGood genuinely heroic]].
* HeroAntagonist: King Minos battles V1 to protect his people and punish the robot for their involvement in humanity's extinction.
* HistoryRepeats: King Minos sending the Minotaur to the Garden of Forking Paths is not only a repetition of what he did to the ''original'' Minotaur in Crete, but also very similar to the way the Father cast Lucifer into the pits of Hell just for questioning him.
* HumanoidAbomination: His soul is a white and blue humanoid being with unfathomable power, red glowing veins, and [[TheBlank a hole where his face should be]].
* KickTheDog: Though otherwise completely benevolent, his decision to cast the Minotaur down into Violence just because he found it hideous and a caricature of his mistakes was a serious dick move.
* LargeHam: While he has fewer lines than Gabriel (not to mention, they're shorter), not only does Minos Prime talk more frequently, but he shouts every word in his battle (except for a small "weak" when he TurnsRed). You can [[ExploitedTrope exploit]] this trope to telegraph his attacks.
* {{Leitmotif}}: Has several. The leadup to the arena he resides in makes use of Maurice Depret's "Sourire d'Avril", which is also used in the buildup to both the first level in the layer he ruled over as well as the fight with his corpse. His battle theme, "ORDER", also incorporates "Requiem", the theme of 2-2, a stage containing several books that explain his backstory.
* LightIsGood: Minos Prime shines with a bright light and is every bit of a benevolent person as he was before he was sealed in the Flesh Prison, and fights V1 on behalf of all of humanity due to the robots being responsible for killing them all.
* LightningBruiser: In contrast with his [[MightyGlacier mighty yet slow corpse]], Minos Prime is ''fast'', agile, and even more durable and deadly than anything in Act 1. [[note]]While Hideous Mass has more HP than Minos Prime, that's undercut by taking triple damage when its weak-points are attacked[[/note]] He made V2 and Gabriel look like total pushovers.
* MessianicArchetype: Wears a crown of thorns, his beliefs are based on love of one another and the forgiveness of one's sins, doesn't fight back when he is to be killed, and is cherished after his death.
* NoGoodDeedGoesUnpunished: He turned a layer of Hell into a paradise out of compassion for its sinners, only to be struck down by the forces of Heaven. Then things go downhill from that point on.
* OOCIsSeriousBusiness: Pretty much all descriptions of King Minos have described him as a kind soul full of compassion for sinners, who was slain by Gabriel because the angel took advantage of his kindness. So when the first words of Minos Prime upon manifesting are said with such ''venom'' and rage, you know that he's been changed by the experience.
* OurSoulsAreDifferent: Prime Souls are souls born from sheer will that become so powerful that ''even angels'' [[TheDreaded fear them]].
* PreExplosionGlow: Beams of light come out of him before he perishes.
* RasputinianDeath: Minos dies a grand total of ''four'' times in Ultrakill: once on Earth before he became a judge of Hell, again when Gabriel slew him and ended his revolution, then V1 kills his corpse, and finally Minos is KilledOffForReal when V1 destroys his ''soul''.
* SealedGoodInACan: The soul of a just ruler who was sealed away in the Flesh Prison for eons until V1 frees him.
* SnakesAreSexy: King Minos has a snake motif as a reference to his poem counterpart, and not only does he have a handsome appearance, he rules the Lust Layer as TheGoodKing. His muscular Prime Soul is well-built like a bodybuilder, and his arms are coiled by ethereal snakes. He even has [[https://newbloodstore.com/products/ultrakill-minos-prime-body-pillow-pre-order official body pillow merchandise]] with one side depicting him [[FlowersOfRomance surrounded by rose petals,]] while the other side has him strike a ReadyForLovemaking pose in all his muscular glory.
* SnakesAreSinister: {{Inverted}}. King Minos has a snake motif, yet he's a kind and selfless king who seeks salvation for his people.
* {{Superboss}}: Minos Prime can only be unlocked by P-ranking Prelude and Act 1, followed by defeating Flesh Prison, who is also this trope. While he solely exists to be an optional yet challenging boss, boy does he ''deliver''. Not only does he take and dish out ''way'' more punishment than V2 or Gabriel, but he's also the ''[[LightningBruiser fastest]]'' boss of Act 1. Only the bravest and most skilled players have a chance to defeat him.
* TechnicolorFire: In his second phase, Minos Prime is [[WreathedInFlames surrounded in blue flames]].
* ThisIsUnforgivable: While Minos is grateful for being freed by V1, he can '''not''' forgive them and their kind for being involved in humanity's extinction, and he will kill V1 for that.
* TragicHero: A benevolent king who was murdered by a self-righteous angel, had his soul sealed away in an EldritchAbomination, watched his undead corpse undoing his and his people's work, freed by a KillerRobot, [[YankTheDogsChain and get permanently killed by said robot]], King Minos is a good soul who was unfairly punished, suffered for an eternity, and met a cruel death at the end.
* TrueFinalBoss: Of Act I.
* TurnsRed: Once half of his health is gone, Minos' attacks get even more aggressive, complete with a cloak of blue fire.
* UngratefulBastard: {{Averted}}. He's genuinely grateful to V1 for freeing him, but given the machines' ''genocide'' of everything that lives on Earth, he is unable to forgive them and attempts to kill his rescuer.
* UniversallyBelovedLeader: King Minos was beloved across the Lust Layer for his reformation of their eternal punishment. So beloved, in fact, that angels feared that after his death, Heaven feared that the belief in Minos was too strong, to the point of his soul becoming a Prime Soul, and thus locked him away in the Flesh Prison.
* WalkingSpoiler: You are not supposed to learn about his soul's existence until you defeat the Flesh Prison.
* WeHardlyKnewYe: The poor soul only serves as a single boss fight, which doesn't survive.
* YeOldeButcheredeEnglishe: He speaks this way, as shown in his quote above.

!!Flesh Panopticon
!!!'''Rank:''' Unclassified
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/ultrakill_fleshpanopticon.jpg]]

A towering creature made of Heaven magic and Hell energy. Just like its predecessor, the Flesh Prison, the Flesh Panopticon also serves as a prison for a Prime Soul.
----
* AntiRegeneration: Its gaze turns all damage taken into ''permanent'' hard damage. This is indicated in the [=HUD=] by the hard damage meter turning yellow.
* BaitAndSwitchBoss: The Flesh Panopticon is set up just like the Flesh Prison before it. But while [[DownplayedTrope there is]] ''[[DownplayedTrope some]]'' [[DownplayedTrope fighting]] with it, the battle doesn't last long. If its first of two health bars is depleted by half or it's given an opportunity to try and heal itself, Sisyphus will interrupt it and violently break free, killing it instantly.
* CriticalExistenceFailure: Averted; The Panopticon was ''barely'' enough to contain the Prime Soul of Sisyphus constantly thrashing around inside it. When it's lost a little over a ''fourth'' of its integrity thanks to V1 fighting it, the prison gives out.
* EldritchAbomination: It's a living flesh cube on top of a stalk with a horrific toothy mouth that goes all around it and a [[EyesDoNotBelongThere plethora of eyes everywhere]].
* FacelessEye: Summons floating eyeball minions.
* FlunkyBoss: Just like the Flesh Prison, the Flesh Panopticon can also summon eyes to help it in battle. Its summons are less numerous than those of the Prison, but they're more resilient, fire explosive beams, and their gaze prevents V1 from healing.
* HealThyself: Subverted. If its health isn't depleted enough for Sisyphus to kill it himself, then he'll break out when it tries to heal.
* {{Leitmotif}}: "PANDEMONIUM".
* LightEmUp: Like Flesh Prison, it can cast holy light pillars similar to the Virtue; unlike Flesh Prison (and Virtues), it can cast them ''horizontally''.
* MacrossMissileMassacre: Sort of. Its most dangerous attack is a barrage of homing, exploding fireballs. They not only do a lot of damage, but turn all normal damage they do into hard damage, severely limiting your ability to recover.
* StationaryBoss: Since it's a tower consisting of a cube on a stick, the Flesh Panopticon doesn't move.
* TrickBoss: It has barely any effective health; as soon as its first health bar is depleted by half, Sisyphus interrupts the fight to destroy the Flesh Panopticon and escape. Downplayed since the Panopticon has dangerous attacks of its own to stand on.
* TurnsRed: Its attacks become more powerful during phase 2. However, it can only be seen in sandbox mode.
* TheWorfEffect: The Flesh Panopticon is noted in its terminal entry to be a superior version of the Flesh Prison used to hold Minos's soul. However, the soul of King Sisyphus is so powerful that the Panopticon can ''just'' barely contain it, and so Sisyphus is able to break out the moment the Panopticon suffers enough damage.

!!Sisyphus Prime
!!!'''Rank:''' Prime Soul
[[quoteright:255:https://static.tvtropes.org/pmwiki/pub/images/sisyphys_prime_1.png]]
[[caption-width-right:255:[[labelnote:Greed Insurrection-era Sisyphus]]https://static.tvtropes.org/pmwiki/pub/images/fl_vqfrwuackdpi.jpg]][[/labelnote]]
-> ''"Come forth, child of man, and'' '''''die."'''''
--> '''Voiced by:''' Lenval Brown

The pure soul of King Sisyphus. Similar to King Minos before him, Sisyphus became an indestructible Prime Soul sometime after his death, requiring him to be sealed within the Flesh Panopticon. Upon his release, he muses about how Heaven has forgotten him and that he is "EAGER to make them remember", before engaging V1 in combat.
----
* {{Acrofatic}}: Depicted as having a rather round midsection, yet he's even faster than Minos Prime, who is skinnier than him.
* TheAntiNihilist: Although he knew full well that his rebellion against Heaven had zero chance of conquering Greed, let alone taking on the whole host of Heaven's armies, Sisyphus remembered the spite he had garnered from an eternity of pushing a boulder up a hill and falling back down to take joy in the simplicity of rebellion against authority itself and not worry about the consequences. Sisyphus permanently dies saying that he regretted nothing, even though his fight was AllForNothing.
* AttackOfTheFiftyFootWhatever: His husk is as big as Minos's, but by the time V1 finds it, it's inactive, being decapitated, restrained, and encased within Greed's largest pyramid. Meanwhile, even though his Prime Soul is significantly smaller, he is still twice as tall as Minos Prime (who himself is twice as tall as V1).
* BaritoneOfStrength: Has arguably the deepest voice of the speaking cast of the game and ''can'' back his register by cashing the asses of the unfortunate souls unprepared for him.
* BitchInSheepsClothing: Downplayed, but it is explicitly stated in terminals that while he was genuinely committed to the idea of fighting against the oppressive reign of Heaven and he made a justified argument for people to follow his lead, his motive to do so was purely out of self-interest stemming from [[{{Determinator}} his deterministic philosophy]] that would always be willing to take on the impossible even if he doesn't have the slimmest chance of victory... thus, he set up a rebellion that would, as he already believed, fail anyway and get numerous members of his rebellion slaughtered en mass by Heaven simply because [[ItAmusedMe it was what he wanted to do rather than for any practical reason]] and doesn't regret leading them all to the slaughter. That said however, upon his resurrection as a Prime Soul, he does make his intent clear to finish what he and his followers started, which implicates a measure of HiddenDepths that has him at least wish to avenge his fallen comrades even if he was the one who led them to die to begin with.
* BloodKnight: After being released from the Flesh Panopticon, Sisyphus Prime fights V1 because he wants to test their combat skills after learning that they defeated Minos Prime. His entry also states that, despite knowing fairly well that his rebellion would fail, he kept at it with a smile on his face up until Gabriel lopped off his head. Sometimes, when you respawn, he'll ''eagerly'' voice his approval of V1's return.
--> ''[[BringIt "Keep 'em coming!!"]]''
* BringIt: Depleting 75 percent of his health will cause him to occasionally stop attacking and perform a gesture like this. Depending on how hurt both he or V1 are, this is either a [[TacticalSuicideBoss split-second opportunity for you to get some serious damage in]] or [[TheWorfBarrage accidentally get cocky and waste your strongest attacks on him]] before he genereously returns the favor threefold.
-->'''Sisyphus Prime:''' [[BossBanter Nice try]].
* CallingYourAttacks: He yells specific lines for his attacks, just like with Minos Prime before him. [[ExploitedTrope As usual, use them as warnings]].
--> '''BEGONE''': A thunderous clap that creates a vertical shockwave. This attack can be parried.
--> '''DESTROY''': Throws a projectile made of gold dust that explodes on contact.
--> '''YOU CAN'T ESCAPE''': 5-hit combo. He thrusts his palms twice, then thrusts his knees twice, and finishes it off with a sumo stomp that creates a shockwave. The stomp can be parried.
--> '''THIS WILL HURT''': After a brief window, he lets out an explosion with a massive blast radius from his body.
* CanonImmigrant: ''ULTRAKILL'' can be considered a very loose adaptation of ''Literature/TheDivineComedy'', based on how it sticks largely to its interpretation of Hell, from King Minos' presence as a judge of Hell to the capital of Dis being set in the layer of Heresy. However, Sisyphus is not mentioned even once in the original poem. Surprising, given Dante's penchant for including figures from Greek mythology in his work and the fact that Sisyphus is one of said mythology's most notorious sinners.
* CombatSadomasochist: Knocking off his first health bar will cause him to both [[TurnsRed literally and figuratively turn red]], but unlike Gabriel who does so out of anger, Sisyphus is clearly getting worked up because he's ''enjoying himself so much''.
-->'''Sisyphus:''' Yes...THAT'S IT!
* DeaderThanDead: Like Minos Prime, the fate of destroying Sisyphus' Prime Soul is permanent death.
* DecapitatedArmy: His army was actually doing pretty good at fighting the Angelic horde, but once he was felled in battle, his insurrection soon followed suit as his soldiers were in a disorganized panic ripe for the slaughter.
* {{Determinator}}: This is entirely why he rebelled in the first place despite knowing what would happen; while he knew actually defeating Heaven was impossible, he believed that rebellion against oppressors even with the knowledge of its inevitable failure was the ultimate victory against the oppressor.
* DeterminedDefeatist: Sisyphus knew his insurrection against Heaven would fail, but that didn't stop him from fighting with all of his might.
* DieLaughing: As opposed to Minos's prolonged scream of agony as he dies, Sisyphus goes out laughing.
-->"So concludes the life and times of King Sisyphus...a fitting end to an existence defined by a futile struggle. Doomed from the very start...and I don't regret a SECOND of it!" (''Belts out some EvilLaughter before he dies'').
* DifficultButAwesome: Sisyphus Prime has attacks that are a lot faster than Minos', but the counterbalance to that is that a lot more of them are parryable, meaning a skilled enough player can basically counter most of his attacks and take off huge chunks of his health bar rapidly. Note, however, that many of Sisyphus' attacks are similar to Minos' parryable attacks in that while they are parryable, parrying them doesn't negate the damage from the attack and V1 still needs to dodge out of the way.
* DoomedMoralVictor: Somewhat interestingly so, in that he ''knew'' he was Doomed with a capital D from the very beginning of it all. He was fully aware his rebellion against Heaven would fail and that he and everyone else would be cut down in the process. He kept going after Heaven even in death, despite being utterly unsurprised he never got that far once killed. Sisyphus is someone that rebels against the tyrants above not because he wants to help, nor because he thinks it'll work. He does it because, just as when he was pushing that rock despite knowing it would roll back down, standing against tyrants even (perhaps especially) when it's pointless is what is ''Right''.
* TheDreaded: Sisyphus Prime is kept behind multiple locks and failsafes, and the entrance to P-2 is well hidden in the City of Dis. Furthermore, in contrast to the pacifist Minos Prime only being guarded by the Flesh Prison, Hell throws '''''everything it has''''' at you to keep V1 from reaching and freeing Sisyphus. This man is bad news, and all of Hell knows it.
* EvilIsBigger: His Prime Soul towers over V1 and Minos Prime, and while he isn't truly evil, he's still a savage BloodKnight with [[TheUnfettered loose morals]].
* FaceDeathWithDignity: Despite knowing his insurrection is doomed to fail no matter what, Sisyphus Prime [[DieLaughing proudly laughs in the face of death]] after V1 defeats him because the mere act of rebellion is enough to bring him joy. [[Creator/AlbertCamus One must imagine Sisyphus happy]].
* TheFaceless: Mimicking his beheading, he has no head, instead having an opaque glowing ball atop his neck with a rough impression of his face.
* FlashStep: He moves so fast that he doesn't even leave particle trails when he's in a new position.
* {{Foil}}: Sisyphus's violent insurrection is contrasted with Minos's peaceful revolution. Minos had great compassion for his people and built a paradise where they could thrive whereas Sisyphus risked letting his followers die while knowing that their rebellion was futile. After they break free of their containment, Minos's words are venomous and spiteful towards Heaven, seeking to kill V1 for their hand in the end of humanity, while Sisyphus is rather tranquil in his declaration of destroying Heaven, picking a fight with V1 because he knew they had killed Minos earlier and wants to test himself against the Machine before resuming his insurrection. When Minos dies, he sorrowfully apologizes to humankind for his failure to avenge their deaths, but when Sisyphus dies, he proudly declares he didn't regret a second of his life and goes out laughing.
* GracefulLoser: Upon his defeat against V1, Sisyphus seems to be despairing about how futile his struggles were... Only to proudly proclaim that [[IRegretNothing he regrets nothing]] before letting out a [[DieLaughing maniacal laugh of pride until he dies for good]].
* HopeBringer: Sisyphus's insurrection inspired hope in an outright hopeless realm, giving his followers something to believe in for once after an eternity of punishment. Sadly, this didn't last long, as his army is swiftly defeated once he is slain.
* HumanoidAbomination: His Prime Soul is a glowing, translucent, towering humanoid being with a sun for a head, a visible circulatory system, has sun-based powers, immense strength, and ''blistering speed''. He's even ''stronger'' than Minos Prime, who's already this trope.
* IRegretNothing: In spite of acknowledging his life as defined by futility and failure, Sisyphus declares this proudly.
* JacobMarleyApparel: His soul is missing its head, replaced by a miniature sun with the vague impression of his face. His hands and feet are still soaked in the blood of his enemies just as they (and those of his Insurrectionists) were during his uprising.
* LeaningOnTheFourthWall: When the player respawns to re-engage him, he remarks "Keep them coming!" as if to imply he's either fought many machines like V1 before, or he's actively aware of V1 respawning.
* {{Leitmotif}}: His theme, "WAR", contains a nod to "Sands of Tide", the theme of stage 4-2, which, much like Minos Prime, contains passages that allude to Sisyphus' backstory as well as the history of Greed, the Layer he came to preside over.
* LightIsNotGood: {{Downplayed}}. Sisyphus Prime is a humanoid soul that's shining with golden light. While he isn't truly evil, he's still a vicious, unscrupulous BloodKnight who's willing to let his followers die in a rebellion he knew would fail, a stark contrast to the good-hearted [[LightIsGood Minos Prime]]. Despite his vices, Sisyphus plans to finish what he started and avenge his fallen comrades, even though he knowingly led them to their doom.
* LightningBruiser: If you think Minos Prime is hard, Sisyphus Prime is ''so fast'' that he doesn't give you ''milliseconds'' to react in time, all on top of having bulk and immense strength.
* MessianicArchetype: He's a bearded, long-haired man with a dark complexion, his domain is a desert, he gets persecuted by religious zealots for finding his radical views blasphemous, he brought hope to his people, and his corpse's arms are outstretched as if he's been {{crucified|HeroShot}}.
* OffWithHisHead: He was decapitated and crucified within his tomb.
* OurSoulsAreDifferent: One of the two Prime Souls formed from an immense will. He's even stronger than Minos Prime to the point that he's ''heavily'' guarded by the Flesh Panopticon and everything else that Hell can throw at V1.
* PreExplosionGlow: Beams of light emerge from him before he dies.
* PosthumousCharacter: Sisyphus is long dead by the time V1 enters Hell. Unlike Minos, Sisyphus' body is inactive; it's encased within Greed's largest pyramid without its head.
* ThePowerOfTheSun: His soul's new face is a miniature sun, he can create small supernovas around himself, and even for metaphorical theming he was king of a layer cast in eternal burning sunlight as well as being the center of his army that all soldiers revolved around and looked to.
* PragmaticHero: His terminal entry quickly states that, unlike the noble and gentle Minos, Sisyphus would very quickly take to more unscrupulous means to protect his comrades. When God had disappeared and Heaven went into a panic, he took this moment to hold his rebellion, even if he knew it would fail, taking advantage of the disarray.
* RageAgainstTheHeavens: Sisyphus's insurrection was this on a layer-wide scale, but it failed once the angels made a concerted effort to strike them down. Terminals state that, even if his rebellion died, he still felt he had won, as he had still managed to rebel against his oppressors even when he knew he would fail in the end.
* SealedBadassInACan: The soul of a valorous yet shady king who was sealed away in the Flesh Panopticon for eons until V1 frees him. Unlike Minos Prime, the Flesh Panopticon ''was barely enough to hold him.''
* StoutStrength: Compared to Minos Prime's more standard athletic build, Sisyphus Prime's frame has the fat to sustain long periods of physical activity he'd need to carry boulders up hills for hundreds of years, and he makes it abundantly clear by having two health bars and being slightly faster than his contemporary.
* {{Superboss}}: If you want to test your mettle against Sisyphus, you must first obtain a P rank in every level of Act II, and defeat Minos Prime, who is also himself this trope. If you manage to do this and then survive the most grueling and difficult combat encounters the game has to offer as of yet, then congrats, you've earned the right to meet Sisyphus in battle.
* TranquilFury: His is a very settled and becalmed sort of bloodthirst, whether he's stating his intent to mangle you solely as practice, or pondering just how ''eager'' he is to tear down Heaven with his own bare hands. He only raises his voice when the battle gets him ''excited'' rather than simply thirsting for vengeance.
* TrueFinalBoss: Of Act II.
* TurnsRed: When you deplete his first health bar, he begins regaining more features of his head, primarily his long hair and full beard.
* TheUnfettered: Unlike Minos, who has a strict code of honor, Sisyphus is willing to lie, cheat, and kill if necessary to achieve his goals.
* UngratefulBastard: Also unlike Minos, who at least thanks you for freeing him before pummeling you into scrap metal, Sisyphus repays your help with the ass-kicking of your life without expressing a shred of gratitude.
* WhamLine: Partway through the fight with the Flesh Panopticon, the fight abruptly stops. Suddenly, you hear a booming voice say, ''"This prison... to hold... ME?"'' Cue Sisyphus Prime tearing his way out of the Flesh Panopticon, utterly destroying it ''within seconds''.
* WorthyOpponent: [[RuleOfThree Once again]], unlike Minos, who challenged V1 for the crimes against humanity they've selfishly committed, Sisyphus just wants to fight V1 because he can sense they've already killed Minos, and he wants a warm-up battle to see their skills before going on a RoaringRampageOfRevenge against Heaven.

->''[[Theatre/{{Macbeth}} Something wicked this way comes]].''
A creature that refuses qualification; a spindly horror stalking [[SecretLevel 0-S]]'s darkened hallways.
----
* DarkIsEvil: It's not called [[NamesToRunAwayFromReallyFast Something]] ''[[NamesToRunAwayFromReallyFast Wicked]]'' for nothing. It's a black, sinister, skeletal creature that lurks in the darkness of 0-S, and it hunts anything that crosses its domain.
* DroneOfDread: Its presence is indicated by a buzzing sound that gets louder as it approaches V1.
* HumanoidAbomination: It's a thin, skeletal, featureless, humanoid creature that's seemingly immortal and makes a [[HellIsThatNoise horrific screech]] whenever it spots V1.
* InvincibleBoogeymen: Something Wicked is borderline unstoppable. While attacking it can stop it temporarily, it will teleport across the map to continue the chase until V1 beats the level.
* KnightOfCerebus: It proves that the secret level it's in will be darker and more serious than the run-and-gun gameplay.
* LeanAndMean: It's essentially a stick figure, and it hunts down V1 during 0-S.
* OneHitKill: Its mere touch causes a whopping 1000 points of damage. The most HP you'll have is 200. This also works against the creature, as a single shot from the revolver can take it out temporarily.
* TheSpook: Nothing is known about it other than that it's incredibly dangerous and doesn't leave its domain.
* VillainTeleportation: Every time it gets shot, the creature teleports to the furthest spot from V1's direction.
* WalkingSpoiler: Since Something Wicked only appears in 0-S, it's this by default.

----
* TheAntiNihilist: Not at the beginning, but the player helps her come to this mindset by the end of their argument.
* CrossPoppingVeins: When Mirage gets frustrated, veins are shown on her portrait.
* DistaffCounterpart: She has a slimmer build and a different head mold, but she acts as one to V1, who is genderless but is often referred to with masculine pronouns by both the fans and Hakita (in casual conversation).
* {{Expy}}: A parody of dating sim love interests who quickly reveals a deeply nihilistic side and a drastic change in personality in not only her words but the world as a whole. Not too far off from [[VideoGame/DokiDokiLiteratureClub Monika]].
* {{Fembot}}: In a schoolgirl uniform, no less.
* JerkWithAHeartOfGold: Mirage is snarky and nihilistic, but the player gives her a new look on life and she (begrudgingly) treats them to food.
* MeaningfulName: She's called Mirage because [[https://steamcommunity.com/app/1229490/discussions/0/3110274289482864562/#c3110274289482866526 she isn't real]].
* SurprisinglyCreepyMoment: What starts off as a parody of dating sims rapidly nosedives into a harrowing debate on existentialism.
* StrawNihilist: Mirage's speech goes into paralyzing fear of action in light of her and everyone's overall meaning - or lack of it - in the face of the universe. The player character helps her get over it, stating that this lack of definite meaning allows one to live as they wish to reach their own meaning that they define themselves, and that the end is not something to be feared, but to be embraced.
* ToastOfTardiness: Her monologue in the level's intro has her mention biting into her rations held only by the skin of her teeth. This is despite the fact that she's a machine with no mouth and, assuming she's like the other machines, uses blood as fuel.
* {{Tsundere}}: She's a massive jerk (although she says it's how she copes with her nihilistic outlook on life), but she treats the player to some food after they wrap up their debate.

* AscendedMeme: The [[https://www.youtube.com/watch?v=cqlWcFdNYwI Hampter meme]] (going by the nickname of "Florp") is popular with the game's fandom. The hamster is finally in the game.
* EasterEgg: The hamster is hidden in one of the Ferry's funnels.
* HumanSacrifice: A ''[[Administrivia/TropesAreFlexible hamster]]'' sacrifice rather than a human one, but Florp is used as a sacrifice to free [[SealedEvilInACan Jakito]].

!!Jakito
A bastardized parody of Hakita's AuthorAvatar. He's found on top of a titanic tower at the start of 5-2. He's trapped in a cage, but for good reason.
----
* AuthorAvatar: He's a bastardized parody of the avatar Hakita uses on social media.
* EasterEgg: Jakito is found on top of a vast tower, which can only be accessed by mastering the game's vertical movement. You ''could'' try using cheats to noclip up there, but then he'll [[NoFairCheating immediately disappear.]]
* TheFourthWallWillNotProtectYou: Should Jakito destroy the world, ''the game closes itself.''
* HumanoidAbomination: Jakito looks like a human (albeit a crudely drawn one), but he's a powerful and malevolent being who destroys the world once he's freed.
* HumanSacrifice: Or rather, ''hamster sacrifice'', but sacrificing Florp is enough to free Jakito from his prison.
* OmnicidalManiac: He wants to destroy the world because he can, and if he's freed, he has the power to do so.
* SealedEvilInACan: Jakito is trapped in a cage, and he needs a sacrifice to be freed. Once he's freed, Jakito destroys the entire world for no reason other than [[ForTheEvulz for the sake of it]].

!Other characters '''(Unmarked Spoilers)'''

[[folder:The Terminals]]
!!The Terminals
[[quoteright:399:https://static.tvtropes.org/pmwiki/pub/images/img_0168.png]]
The various screens you see between levels and encounters, allowing you to buy weapons, read documents on the different enemies and events of the world, and access the Sandbox and Cyber Grind game modes.
----
* AllergicToRoutine: The main reason they use "points" as a currency is because of their completely sedentary existence, a lack of surface world stimuli, and the otherwise drone-like nature of most Machines has made them yearn for some kind of entertainment. So, they reward machines that show off their skills with a chance to earn better weaponry.
* DeadpanSnarker: The Terminal just before the Flesh Panopticon has one unchanging tip for you going into the fight;
--> "TIP OF THE DAY: [[ComeToGawk Have fun]]"
* DungeonShop: Just before heading out into the levels of Hell, V1 can buy weapon variations and weapon customization options from them. Some will even appear just before boss battles, with P-2 having a terminal after the many enemies found in Dis and before fighting the Flesh Panopticon.
* ItCanThink:
** Until you beat a Prime Sanctum, you might be led to believe that the terminals are just non-thinking machines that provide basic utilities. The terminal at the end of P-1 hints at the sentience of the terminals, referring to the machines' usage of them as "a symbiotic relationship", and the terminal at the end of P-2 outright describes their behavior and desire for entertainment.
** A blink-and-you'll-miss-it moment at the end of 5-3 also shows they are able to react to outside stimuli, and either feel pain or have a sense of humor, when you find one that was tipped over when the ship capsized:
-->'''TIP OF THE DAY:''' Ow.
* MoneySink: In addition to regular weapon variations, their merchandise includes weapon customization options that require 5 million points in total to acquire.
* MonsterCompendium: They hold a record of every enemy and boss V1 has fought, as well as observations on their behaviors and how to best handle them.
[[/folder]]

[[folder:Humanity]]
The previous dominant race on Earth, now gone extinct thanks to the rise of the machines.
----
* AlternateHistory: What people call the Final War has its roots in what used to be recognizable as UsefulNotes/WorldWarI, a version of it that simply kept going through the entire 21st century.
* CrapsackWorld: The Guttertank's terminal entry notes that things were going pretty poorly for mankind even off the battlefield, as most of humanity's resources were being used for the war and little was going into civilian life, with most struggling to survive. It's to the point that the sun being blotted out by the soot and ashen ruins of the war is considered a ''good'' thing, as it shut down the Earthmovers and ended the war.
* GreatOffscreenWar: In 1914, the Final War started among humankind. Little is seen of it, though it is known that the conflict dragged on for approximately 200 years and culminated in human soldiers being supplanted by increasingly sophisticated machine armies.
* HumanitysWake: The entire game takes place after all humans have been wiped off the face of the earth.
* HumansAreFlawed: Hell is full after all, and there are a great number of humans who have committed sins against one another. This eventually culminated in the Final War... but war still ended after all, and humanity got past their differences for peace. Ironically enough, humanity was seemingly instead ended by a being of pure evil that was incensed at humanity moving on past a life of violence into peace, provoking it into ending humanity itself directly.
* HumansAreSpecial: Unlike the other races, humans are the only race to not only have souls, but form Prime Souls, beings so powerful they can manifest a physical form without the need for a Husk, and they're dreaded even by ''Angels''.
* LensmanArmsRace: The Final War ended up becoming one as humanity invented the Gutterman, which was countered by the Guttertank. Continue on until you reach the Earthmovers and possibly V1.
* TooDumbToLive: Creating machines that derive their fuel source from blood probably wasn't the brightest idea, given that the machines are also sentient and don't intend on dying, not to mention that humanity still made such robots even after the Final War ended. However, the ARG puts ''this'' idiocy into question with the reveal [[TheManBehindTheMan that an entity had a hand instigating]] the extinction of humanity with the intent of stealing away the souls of mankind to torment for its own amusement for all eternity, and nowhere is it actually stated that it was machines that caused the great calamity. [[DoubleSubversion On the other hand]], sending at least two research expeditions into Hell is what gave the entity access to human technology, including blood-powered machines, in the first place...
* WarIsHell: The Final War was such a desperate and pointless struggle, [[CrapsackWorld it even burned holes in civilian life and rendered home as just another battlefield for the soldiers discharged after the arms race began]].
* WowingCthulhu: The GreaterScopeVillain of the story that caused humanity's extinction for its own purposes is nonetheless awed by the sheer destructive potential the species had when putting their work towards creating the war machines. The Earthmover is practically idolized as the perfected state of this, poetics waxed at length in a book it left to narrate its thoughts to V1 on the matter, and the Guttermen [[HumanResources designed to carry their fuel sources]] ''inspired'' said entity to take notes for its own unholy creations. Humanity was so royally fucked up that it earned VillainRespect for it.

[[folder:Terminal Author]]
An unknown person who wrote the lore entries on the terminals found at the end of Prime Sanctums.
----
* ContentLeak: InUniverse, the lore from the end of P-2 mentions that a previously-written draft got leaked, and they had to deal with the repercussions.
* DeadpanSnarker: Marked comment text has them cynically snipe at whoever they're frustrated with, such as the "suits" who didn't bother reading their previous giant text block, or complaining about a project lead's music choice at the terminals.
-->[note: fuck you tom im so fucking tired of this stupid song and having to listen to it every morning over your garbage intercom]
* KilledMidSentence: The lore from the ARG that appears to be written by them has them stop typing suddenly, followed by multiple lines of blank text, and then an evil force interjecting and ordering another person to die.
* OOCIsSeriousBusiness: Their typing style is defined by occasional frustrated comment text in grey. The ARG lore entry, addressed to the same Tom from an in-game lore entry, has none of that, as [[OhCrap they've realized the gravity of the situation and the importance of getting a message sent immediately]].

[[folder:The Father]]
!!The Father
The creator.
----
* AdaptationalWimp: The God of Literature/TheBible was an all-powerful being with no limit to His might. But the Testaments found in the secret levels imply that, no matter how hard how He tried, this version of Him could never create a human being [[TheEvilsOfFreeWill that lacked free will]]. Furthermore, though He was able to create Hell, He has admitted that He no longer has the power to unmake it.
* DespairEventHorizon: Every Testament so far has shown that he's clearly hit it since before he started writing them. It's hard to figure out what exactly started it, but it was either the creation of mankind or the creation of Hell.
* DisproportionateRetribution: For asking if eternal torment for sinners was justified, He cast Lucifer into Hell. He was frightened by the possibility of admitting He was wrong, [[MyGodWhatHaveIDone but afterward realized just what He did.]]
* TheEvilsOfFreeWill: The secret level Testaments document God's attempt to create humans without free will, His failure at doing so, and the subsequent creation of Hell to punish sinners who don't follow His rule.
* GodIsDead: In the Act 2 end credits, Gabriel confirmed that God has been dead for a while.
* GodIsFlawed: In several secret areas, you can find special "TESTAMENT" Terminals that reveal God's own inner thoughts about mankind in His attempts to engineer free will out of them. Every single attempt fails, and it's clear behind the grandiose, all-caps speech pattern is a burnt-out wreck lashing out at others because He can't comprehend not being able to do something, and only realizing the error in this after He creates Hell, and realizes He can't change what results from ''that'' either. WordOfGod has stated this is fully intentional, with God's limits in power, knowledge, and benevolence serving to justify why he would ever create [[FateWorseThanDeath Hell]].
* HaveYouSeenMyGod: The father hasn't been seen for a while. It is implied that He may be dead.
* MyGodWhatHaveIDone: God horrifies himself when he casts Lucifer into Hell when [[ArmorPiercingQuestion he asks what could possibly justify the eternal torment of humanity]].
* OOCIsSeriousBusiness: If the Testaments are any indication, He speaks in [[CapsLock all capital letters]] and [[RhymesOnADime rhymes the last word of every second sentence]]... right up until the last line of Testament III, where He realizes to His horror that after having failed to change mankind's free will and creating Hell out of frustration, He isn't able to undo it.
-->I HAVE CREATED HELL...\\
...And now I can no longer unmake it
* TheMaker: He's the creator of both Heaven and Hell.
[[/folder]]

[[folder:The Council]]
!!The Council
A corrupt council of Angels that rule over Heaven after God died.
----
* AssholeVictim: Gabriel slaughtered the entire Council at the end of Act 2. Don't pity them, since The Council is [[FantasticRacism xenophobic]], [[HolierThanThou self-righteous]] tyrants that ruled Heaven through fear and made Hell as miserable as possible.
* BadBoss: They consider Gabriel's defeat at the hands of a machine tantamount to treason and heresy, and punish Gabriel for it. [[TheDogBitesBack This comes back to bite them in the ass later]].
* CouncilOfAngels: The angelic council took over once the Father left.
* GreaterScopeVillain: They ruled Heaven with an iron fist, their teachings made Gabriel just as dogmatic as they are, and they're responsible for some of the horrific punishments and events in Hell, like the fall of Minos' Lust Renaissance, the failure of Sisyphus' Greed Insurrection, and the deaths of both kings. However, there's an even ''greater force of evil'' that's pulling the strings from beyond the veil.
* HateSink: There is nothing entertaining or sympathetic about them, being nothing but self-righteous tyrants that caused horror and misery long before the game's plot took place.
* ItIsDehumanizing: During their judgement of Gabriel at the end of Act 1, the Council deliberately avoids using gendered language, referring to Gabriel as an "it" or "this one." Surrounding context makes it clear that they see Gabriel as unworthy of respect.
* KarmicDeath: The entire Council are corrupt Angels who ruled Heaven through fear, created the horrible punishments in Hell, instilled their dogma onto Gabriel, and then severed him from God's light for losing to V1. Gabriel comes back to Heaven at the end of Act 2 to butcher the entire Council, and they all deserve it.
* LightIsNotGood: They're Angels of holy light, yet they punish Hell's sinners with immense suffering and rule Heaven through fear and desperation out of their [[KnightTemplar self-righteous dogmatism]].
* TheUnfought: Despite being major villains, the Council was never fought by V1. Instead, they were slain by Gabriel in the ending cutscenes of Act 2.

[[folder:Lucifer]]
!!Lucifer
->''"FATHER, [[ArmorPiercingQuestion WHY ETERNAL TORMENT]]? IS IT NOT CRUEL?\\
IS TORTURE UNENDING TRULY A FATE FIT FOR A FOOL?"''

The First Fallen Angel. As revealed in Testament IV, he was cast into Hell after he asked God why He was sentencing humans to eternal torture.
----
* AdaptationalHeroism: In [[Literature/TheDivineComedy the poem]], Lucifer betrayed God out of his own arrogance, despite knowing that this crime will bring evil and suffering to the world. In this game, sin already existed in the world [[TheEvilsOfFreeWill as a necessary consequence of free will]], and Lucifer merely questions the creation of Hell out of genuine concern for humanity, despite seeing sinners as fools.
* AngelicBeauty: Even by the standards of other Angels, Lucifer was noted by God to be "bright and beautiful".
* ArmorPiercingQuestion: Asked God what could possibly justify [[AndIMustScream Hell and the eternal torment of humanity]] for [[DisproportionateRetribution meager sins]]. In that moment, God became stricken with terror, and cast Lucifer into Hell as well.
* FallenAngel: Lucifer is the first and only known Angel to be casted into Hell, though this is a result of him simply questioning God about the creation of Hell rather than any act of malice.
* HeKnowsTooMuch: Lucifer was the first, and the only known, Angel to question God whether Hell was justified. Frightened from the possibility of revealing his personal failing, God had Lucifer banished to Hell as well.
* LightIsGood: [[SatanIsGood Lucifer]] is described as "[[AngelicBeauty bright and beautiful]]'' by God, and he is the first and only known Angel to sympathize with humanity by questioning God if the creation of Hell was justified.
* MeaningfulName: Described by God as "bright and beautiful". Lucifer translates to "bringer of light" in Latin.
* NoGoodDeedGoesUnpunished: Lucifer was casted into Hell by God for questioning the creation of Hell out of sympathy for the human sinners.
* PetTheDog: While he considers sinners to be foolish, he still showed them more sympathy than God did.
* {{Satan}}: The First Fallen Angel himself, [[AdaptationalHeroism though he's far more sympathetic and noble than his poem counterpart]].
* SatanIsGood: Lucifer was cast into Hell for questioning God's eternal punishment for sinners, which God Himself immediately regrets. He's also not the real villain, but ''something'' else is.
* SympathyForTheDevil: In a fit of {{irony}}, it's ''[[SatanIsGood The Devil]]'' who's pulling this trope off. While he sees sinners as fools, Lucifer still feels sympathy for them and questions God if the creation of Hell was justified.
* WhamLine: The mere mentioning of his name reveals that he's the Angel who was questioning God in Testament IV, along with confirming his existence in the ''Ultrakill'' universe.

[[folder:ARG SPOILER CHARACTER]]
!!Hell
->''"a n o t h e r d i e s . b r i n g m e m o r e . i h u n g e r .''"

Yes, {{Hell}} itself. The realm of eternal torment created by God to punish sinners, Hell is revealed [[GeniusLoci to be alive]] by the second part of the AlternateRealityGame that started since the release of "Tenebre Rosso Sangue".
----
* AbusiveParent: Hell is the creator of the Demons, yet it has no love towards what are essentially ''its own children''. Hell displays this callousness by sending its Demons to be slaughtered by V1, so it can watch the bloodshed out of sadistic glee. Hell also left [[TragicMonster The Minotaur]] to rot in the Garden of Forking Paths for a millennium before luring it to the exit room... only to [[YankTheDogsChain take away that hope of freedom]] and forcing it to battle V1 in a losing duel, resulting in the Minotaur dying with regret for failing its [[TragicDream dream of seeing the sky one last time]].
* AdaptationalVillainy: In ''Literature/TheBible'' and [[Literature/TheDivineComedy the poem]], Hell is a place of punishment, but it never extends beyond that. Here in this game, Hell is not only alive, but evil, being a sadistic realm that's implied to wipe out the entire human race so it can claim their souls and torture them for eternity as an act of twisted entertainment.
* AlienGeometries: The layers of Hell are weird, which becomes more obvious at the end of Act I onwards. Many levels seem to exist in utterly massive locations, with unobstructed skies and a horizon that goes on for miles, even though you came in by dropping down a shaft from what may have been another massive location with an unobstructed sky and miles-long horizon. You can sometimes see the shaft the level entrance connects to reaching upwards seemingly infinitely, other times it's inside of a structure you can climb to the top of without ending up back in the previous level. Also, the entrance to Gluttony is somehow inside the mouth of The Corpse of King Minos, despite the layer not actually being within the corpse itself.
* TheAntiGod: A unique example in that it was created by God himself. Hell is an immeasurably powerful being that not even God could unmake, creates the common Demons to torture its prisoners, idolizes the soulless machines humanity created to wage war, something essentially every heavenly character despises, and is motivated entirely and exclusively by a desire to [[{{Sadist}} torture]] and [[OmnicidalManiac destroy]] seemingly ''everything''. This is even reflected in its presentation in the story, where it speaks in massive, all-capitalized red text that's similarly scornful and cruel to God prior to creating Hell when describing its ideal fate for humanity: entirely exterminated by the machines in a show of total meaninglessness. Disturbingly, while there are signs it may be guiding V1, [[DevilButNoGod God himself has vanished entirely, if not having outright died]].
* AppearanceIsInTheEyeOfTheBeholder: Hell's makeup changes to some degree for those who come in through the "Prelude" area, with transition zones appearing such that one can progress further through no matter what path they take.
* BigBad: The Part 2 AlternateRealityGame seems to be building up Hell as the game's main villain, and it's responsible for modifying Husks like the Soldiers and the Stalkers, locking down arena doors, and spawning enemies. It's also implied that Hell is the sole cause for [[HumanitysWake humanity's extinction]].
* CirclesOfHell: Like its [[Literature/TheDivineComedy poem counterpart]], Hell in this game is divided into nine layers, with Fraud and Treachery currently under development.
** Limbo: A [[GreenHillZone lush and green Greco-Roman paradise]] that is [[CrapsaccharineWorld anything but]], as its fake serenity in the form of flat screens posing as skies, fake plants, hologram waterfalls, and sounds of wind and bird songs coming from hidden speakers, drives its sinners to insanity.
** Lust: A [[MetropolisLevel black and purple Victorian city]] with sprinkles of {{Cyberpunk}} elements. Unlike Limbo, [[AHellOfATime Lust was a genuine paradise]] thanks to the efforts of King Minos and his beloved subjects, until Gabriel slays the king for freeing Lust's sinners from their torment. Now under the control of [[PuppeteerParasite the parasitic serpents]] he once commanded, [[UndeadAbomination King Minos' reanimated and colossal corpse]] searches the once prosperous kingdom for sinners to punish.
** Gluttony: Unlike its poem counterpart, which is described as a realm of icy mud, this game's version of Gluttony is depicted as [[EvilIsVisceral a visceral]] [[WombLevel red realm]] filled to the brim with flesh, teeth, acid, giant stone hands, and [[TheWallsHaveEyes numerous eyes covering the surfaces]], with gaping mouths serving as the layer's doors. This is the first layer that's [[YouDontLookLikeYou depicted completely differently]] from its poem counterpart, [[BloodyBowelsOfHell being a visceral Hellscape]] rather than a slimy snowscape of scum and mud [[note]]It is closer to appearance to the Circle of Gluttony as depicted in VideoGame/DantesInferno[[/note]]. King Minos' Prime Soul is imprisoned in this layer.
** Greed: A [[ShiftingSandLand yellow desert layer]] with [[BuildLikeAnEgyptian Egyptian elements]] such as pyramids and mural art. Sinners are punished by rolling boulders across large pyramids in the scorching heat of the blazing bright sun, and the "sand" is actually burning hot flakes of gold that burn almost everything it touches. The layer was once ruled by King Sisyphus, who, unlike King Minos, led a violent rebellion against Heaven and its army until he was decapitated by Gabriel, who then swiftly finished off Sisyphus' remaining forces with his fellow Angels.
** Wrath: A [[UnderTheSea blue ocean layer]] with nautical aesthetics, unlike its poem counterpart which is a swamp. The Styx was once a river until it turned into a vast ocean, thanks to ''millions'' of sinners populating this realm. The sinners are forced to struggle against each other for air, and the ones that don't sink to the ocean's abyss out of despair, where Hell energy and their collective agony merge them together to form [[KrakenAndLeviathan The Leviathan]], a titanic, serpentine Demon that [[TheAssimilator absorbs]] the despair-ridden sinners into its body to grow bigger and stronger despite being bounded to the Styx by Gabriel.
** Heresy: A [[RedAndBlackAndEvilAllOver sinister red and black]] [[PlanetHeck Hellscape]] resembling a [[CreepyCathedral cathedral]] decorated with [[GruesomeGoat goat skulls]], chains, and {{lava pit}}s. This layer is the closest thing the game has to [[FireAndBrimstoneHell a typical depiction of Hell]]. King Sisyphus' Prime Soul is imprisoned in this layer, in the city of Dis, a dark, hellish cityscape where every window is blazing red by the burning souls of the heretics and it constantly rains blood.
** Violence: An [[BleakLevel almost completely barren, white field]] that's shrouded in fog. The outermost part of the layer is made up of a large, pristine megastructure that serves as a labyrinth to prevent escape, its architecture like a mausoleum or art museum populated by sentient mannequins. The layer is divided into three rings: violence against others, violence against oneself, and violence against God. The first ring takes WarIsHell literally by being a near pitch-black ForeverWar accompanied by searchlights, blazing gatling guns, and a trio of colossal machines. The second ring is a garden of trees with humanoid shapes in their branches in perpetual agony. The third ring is a barren wasteland under an endless rain of fire, where [[HumongousMecha The Earthmovers]], colossal war machines that are the pinnacle of the LensmanArmsRace, stride around and prey on each other.
* ColorCodedSpeech: Hell's dialogue is generally identifiable by all-red text.
* DarkIsEvil: Five of its layers, Lust, Gluttony, Wrath, Heresy, and Violence (after [[LightIsNotGood 7-1]]) are shrouded in darkness, and with the exception of Lust (until Gabriel killed King Minos), they all exist to torture its sinners.
** Lust is a black and purple realm that punishes sinners by blowing them away with strong winds. However, it temporarily becomes DarkIsNotEvil when King Minos and his people [[AHellOfATime reformed the layer into a thriving paradise for themselves]] until he was slain by Gabriel for freeing the layer's sinners from their punishment. Now his corpse becomes a colossal zombie controlled by serpentine parasites, Hell-bent on finding sinners to punish.
** Gluttony combines this trope with EvilIsVisceral, being [[BloodyBowelsOfHell a dimly-lit realm of flesh]] where sinners are punished by being merged into its surfaces. The layer is decorated with giant stone hands and teeth, disembodied mouths serve as doors, pools of acid fill the bottom of its rooms, and [[TheWallsHaveEyes eyes cover its surfaces]]. Open spaces are surrounded by pitch-black darkness, which is best shown in 3-1's stairway arena, 3-2's boss arena, and P-1's spinal stairway.
** Wrath is a dark, raining, watery realm shrouded in lightning storms where sinners suffer by drowning in the river (now ocean) Styx while [[WeAreStrugglingTogether struggling against each other]] for a chance to breathe. Those who sank to the Styx's abyss [[DespairEventHorizon out of despair]] are merged together by Hell energy and their hopelessness to form the Leviathan, a towering, serpentine demon born from the still-living souls of despair-induced sinners that are doomed to [[FateWorseThanDeath a horrible fate]] where all they can do is [[AndIMustScream scream in their collective agony]].
** Heresy is [[ObviouslyEvil explicitly]] [[FireAndBrimstoneHell the most sinister layer]] in appearance, resembling a [[CreepyCathedral gothic black cathedral]] decorated with goat skulls, blood-red windows, and vermillion doors made from the souls of heretics. Its hallways are shrouded in darkness and red fogs, [[RedSkyTakeWarning a blazing red sky looms over the horizon]], and the City of Dis [[RainOfBlood is raining blood]]. Overall, The Heresy Layer wears RedAndBlackAndEvilAllOver as a badge of pride, welcoming you with a DroneOfDread as soon as you enter 6-1.
** The Violence Layer starts off as LightIsNotGood, since it invokes WhiteAndRedAndEerieAllOver by V1 staining the white layer red with their enemies' blood. However, it pairs this trope starting in 7-2 where the 1st ring is a near pitch-black ForeverWar with [[RiversOfBlood the blood river Phlegethon]] sitting below the warzone while searchlights and hails of bullets are piercing the darkness with bright white explosions illuminating the background to show the [[SinisterSilhouettes ominous outlines]] of three titanic machines whose white eyes glow in the all-consuming darkness. 7-3 continues this trope by being a near pitch-black garden illuminated by red agonized trees, before it brings back the [[LightIsNotGood eerily bright white room of 7-1]] for the final arena. Finally, 7-4 settles on this trope by being a dark gray desert with a blood-red night sky that [[EvilIsBurningHot rains Hellfire]].
* TheDogWasTheMastermind: Who knew that the place you were invading is pulling the strings all along?
* EarlyBirdCameo: While Hell is only introduced in the ARG following P-2, material in ''ULTRAKILL'' hints at its existence prior. The Soldier and Stalker's modifications are said by the Terminals to be created by an unknown, sentient force, while Terminals in P-2 and the door panel right before Flesh Panopticon borrow Hell's signature text style of red text and/or incorporating a space between each letter of all words.
* EldritchAbomination: Also overlaps with EldritchLocation. Hell is a ''[[GeniusLoci living]]'' realm of eternal suffering, and its locations are separated into [[CirclesOfHell nine layers]], each with their own biome and AlienGeometry. It can also steal and modify technology for its own goals, lock down doors, and teleport beings to its targeted locations.
** [[WordOfGod Hakita has explained]] (albeit while also stating it's hard to describe) that the layers of Hell are not physical places in the normal sense, being very abstract and, despite V1 progressing by descending through the layers, do not exist in parallel, hence each layer acting as if the above layers do not exist, nor accounting for how one gets in them (such as Lust, Greed, and Wrath having visible skies and Gluttony not actually being inside of Minos' corpse despite the entrance being found inside his mouth.) It apparently appears different for everybody, with the level entrances and exits simply not existing for those resident to the layer, and if one wants to progress through Hell, there apparently is no "wrong path" and you will keep going further. In short, Hell's makeup is an abstract that varies from one's perception.
* EvilIsHammy: Its monologue in 7-4 is the most dramatic piece of lore in the game, full of flowery prose that would make the Testaments blush, and going by how the book is blank, it's all but stated it's Hell [[EvilGloating monologuing to V1]] through their scanning interface. Likewise, when V1 finds themself blocked later in 7-2, what seems to be Hell, going by the red text, says "[[LaughablyEvil WE'RE GONNA NEED A BIGGER BOOM]]", which compared to past interface messages such as "INSUFFICIENT FIREPOWER" and the like is very... grandiose in its own way. Also, a secret terminal in 7-3 that opens the "[[GangUpOnTheHuman Marked For Death]]" crystal displays an ''even more grandiose'' message, possibly from Hell itself due to the red text, that says "YOU'RE THE STAR OF THE SHOW NOW, BABY!", like a campy TV game show host... ''[[EvilHasABadSenseOfHumor In the ring of sinners that killed themselves]].''
* EvilIsPetty: At the end of 7-1, V1 is approaching one of the level exits, which are under the control of Hell, only for the Minotaur to burst through, clearly desperate for its own chance to escape the labyrinth and see the sky one last time. Hell responds by ''closing the exit door even after it was already open'', something it doesn't do anywhere else in the game, forcing both of them into a fight to the death - one which might have been avoided had Hell not closed the doors [[PragmaticVillainy given the Machines' extreme reluctance to waste resources]].
* FatalFlaw: For all of its power and intelligence, Hell's {{sadist}}ic craving for death and suffering [[StupidEvil at the cost of its own self-preservation]] will be its downfall, as Gabriel implies that Hell will be completely empty by the time the machines have their fill. A large part of this could be attributed to the fact that Hell outright teleports Husks and Demons before V1 so they can kill them. However, given its glowing praise of the Machines and their own inevitable demise whenever they run out of fuel, it's questionable whether it even ''cares.''
* ForTheEvulz: Hell is a sapient realm of eternal torment, but even billions of sinners aren't enough to satisfy it; thus, it uses its influence to set up combat encounters, turning its victims into yet more weapons to fight, all for the sake of a violent show.
* GeniusLoci: As revealed by the Part 2 AlternateRealityGame, it reveals that Hell is not just a location, but also a creature that's described as a massive, intelligent superorganism. It is also a malevolent being that seeks to claim as many souls as possible while entertaining itself with the suffering of its victims.
* {{Hell}}: Obviously. But not only is it [[CirclesOfHell layered in the style of Dante's Divine Comedy]], it's a living, thinking, and wicked realm.
* {{Hellevator}}: The Hell Expedition team installed numerous elevator systems throughout Hell, allowing V1 to descend one layer at a time.
* ItCanThink: What was once thought to be a mere EldritchLocation is anything but, being revealed to be [[GeniusLoci a living entity with a twisted mind]]. While the human Hell expedition team was exploring it, they hardly were aware that Hell was learning how their machines worked, and that it was behind the creation of its own technologically augmented Husks.
* KillAllHumans: The Part 2 [=ARG=] implies that Hell is the sole perpetrator of [[HumanitysWake humanity's extinction]], since its influence has spread to the surface world to wreak havoc with its army of modified Husks and Machines.
* KillEnemiesToOpen: Provides the {{justif|iedTrope}}ication: Hell is capable of causing doors to shut closed as it teleports enemies in. This was initially assumed to be just doors malfunctioning by the Hell expedition team, and then the terminal author learned otherwise.
* LightIsNotGood: Three of Hell's layers have bright color schemes, yet they all serve the same purpose as any other layer: Torturing its sinners.
** Limbo seems to be a Greco-Roman paradise with bright blues and greens, yet [[CrapsaccharineWorld it's a false paradise]] that drives its sinners to insanity with its fake serenity in the form of fake trees, fake water, fake bird songs, and fake skies.
** Greed is a bright yellow Egyptian desert that tortures its sinners with scorching heat from its own sun and the "sand", which are actually burning hot flakes of gold.
** Violence is an eerie white graveyard-like wasteland with a vast maze-like mausoleum filled with Mannequins. It also invokes WhiteAndRedAndEerieAllOver, thanks to V1 staining the white layer red with the blood of their foes. {{ZigZagged|Trope}} in 7-2 and onwards where while the first room of 7-2 has an eerily white color, DarkIsEvil and RedAndBlackAndEvilAllOver are added to the mix, thanks to the 1st ring being a dark ForeverWar surrounded by [[RiversOfBlood the blood river Phlegethon]] and being guarded by the giant war machines that are shrouded in darkness until an explosion illuminates the background to show their SinisterSilhouettes. The second ring, 7-3, starts off in a pitch-black forest of darkness until its final arena becomes blindingly white like 7-1. Finally, the third and final ring, 7-4, settles onto DarkIsEvil by being a dark gray desert with a crimson night sky that is [[FireAndBrimstoneHell raining Hellfire]].
* OmnicidalManiac: A secret book found during 7-4, which raves about the beauty of the apocalyptic Earthmover machines, implies that it believes life on Earth should've ended with said Earthmovers - the culmination of all that is warfare for its own sake - should've killed every human alive, and then died off themselves, leaving the land empty. "No final words. No concluding statement. No point. Perfect closure". The same book also implies that Hell ''is pissed'' that humanity actually survived this and moved past this perpetual warfare, thus Hell took action against them.
* PaintingTheMedium: When Hell first speaks at the end of the Part 2 [=ARG=], its text is distinctly written with all letters and punctuation separated by singular spaces, as can be seen in the quote above. This style of text also appears at several points in the game (such as with several lines of text before the P-2 boss and at the end of the secret book in 7-4), strongly implying that Hell is the one speaking/writing in those cases. Additionally, regardless of whether its text is spaced or not at the time, its dialogue is always written in blood red.
* RedAndBlackAndEvilAllOver: The Heresy Layer ''([[FireAndBrimstoneHell especially Heresy]])'', and the Violence Layer (aside from [[WhiteAndRedandEerieAllOver the eerily white 7-1]] and the [[GreyscaleOfEvil ash grey 7-4]]) both have a sinister red and black color scheme, and Hell is a {{sadist}}ic GeniusLoci that wiped out all surface life on Earth to claim their souls and torture them for all eternity for sick kicks. Even its texts reflect this trope by being [[PaintingTheMedium bloody-red, all-caps text with pitch-black backgrounds]].
* RedIsViolent: Hell is associated with the color red, and it's a {{sadist}}ic realm of torment that entertains itself by creating violent gladiator games. It also wants to [[OmnicidalManiac wipe out all life on Earth]] with [[WeaponOfMassDestruction the Earthmovers]], and when they failed, it's implied that Hell took matters in its own hands by slaughtering every living being on the surface to claim their souls.
* {{Sadist}}: If torturing human souls ''for an eternity'' out of sick kicks wasn't enough, the AlternateRealityGame states that Hell invaded the researchers' facilities not to protect itself, but to entertain itself by trapping the researchers before slaughtering them with the modified Husks and Machines it has created. All of the in-game mechanics, like the arena encounters and enemy spawns, are all for its own twisted entertainment.
-->''this is not an attack. this is not a defence. this is entertainment. this is an exhibition of death and cruelty and suffering [[ForTheEvulz for its own sake]].''
* SatanicArchetype: Since Lucifer is implied to be [[SatanIsGood more kind-hearted than the norm]], it is Hell itself that takes on some of the stereotypes associated with Old Scratch by being an infernal, all-powerful overseer that tortures both its own residents and innocent lives on the surface for its sadistic amusement.
* SophisticatedAsHell: Excuse the pun. The few cases we see of Hell's own thoughts and text are usually either some matter of directive, a PreMortemOneLiner or it waxing immense and complex poetry worthy of ''The Divine Comedy'' inspirations. Then you hit 7-2 and, if the red text is still Hell, it proceeds to casually state "WE'RE GONNA NEED A BIGGER BOOM" so that V1 gets the hint to find the payload bombs in the area for blowing open a blocked passage, as if taking a break from its ominousness just to cook up an excuse for more bloodletting. Also, a secret terminal that opens the "Marked For Death" crystal in 7-3 shows a text possibly from Hell saying "YOU'RE THE STAR OF THE SHOW NOW, BABY!", like [[EvilIsHammy a hammy TV game show host]]... [[EvilHasABadSenseOfHumor In the middle]] of a literal ''suicide forest''.
* VillainRespect: With how cruel Hell itself is to its subjects, it says a lot about [[HumansAreBastards mankind]] that it found ''inspiration'' in the way Guttermen employ HumanResources. In fact, a secret book in 7-4 is full of praise bordering on idolization for the apocalyptic destruction of the Earthmovers, and perhaps even V1.
* WalkingSpoiler: The fact that Hell is alive is a ''huge'' bombshell to the game's lore.
* WardensAreEvil: An unusual example where the warden is ''[[GeniusLoci also the prison]]''. Hell itself devotes its existence to torturing its prisoners and forcing them into violent duels out of sadistic pleasure.
* WhamLine: The second paragraph of the Part 2 AlternateRealityGame drops the bombshell that ''Hell'' is alive, intelligent, and '''malevolent'''.
-->''[[GeniusLoci hell is alive]]. it breathes. [[ItCanThink it thinks]]. the entire area is a massive intelligent superorganism and [[{{Sadist}} it is harsh]] and [[ForTheEvulz it is cruel]].''
* WickedCultured: Hell itself may be a sadistic realm of torment, but it can be surprisingly eloquent in its writing, as shown by the secret book in 7-4 where it praises The Earthmovers with such rich poetry that it would make Dante envious.
* YankTheDogsChain: It's implied that Hell allowed both the Lust Renaissance and the Greed Insurrection to exist, [[HopeCrusher just so it can watch both of them fail and relish in the following misery]]. It pulls this trope off again, this time to both V1 and especially the Minotaur in 7-1 where it opens the {{Hellevator}} before suddenly closing it once the Minotaur returns, forcing them into a duel to the death where V1 kills the Minotaur and crushes the beast's TragicDream of freedom to see the sky one last time.
* YourSoulIsMine: Hell's motive to wipe out the human race is to claim their souls so it can entertain itself by torturing them for all of eternity.
[[/folder]]

* OurMinotaursAreDifferent: This one isn't a half-man, half-bull hybrid, but a grotesque demonic amalgamation of flesh and stone in the vague shape of a bull given as a "gift" to King Minos. Its terminal entry states that it's a reproduction based on the ''original'' Bull of Minos (which is why Minos hated it, [[MyGreatestfailure as it reminded him of that time that he let his wife get impregnated by a bull and then had to feed their child seven children every month for several decades]]), indicating that a more traditional Minotaur existed at one point in the ''ULTRAKILL'' universe as well.

* MechanicalAbomination: They are an entire species of machines that have not only killed off all of life on the surface of Earth (and may or not be the cause of the extinction of humanity) but are now going down to Hell itself to get more blood in a frantic run to stay active.

* {{Expy}}: He fills the role of both [[Characters/DevilMayCryVergil Vergil, Son of Sparda]], and [[Literature/TheDivineComedy Virgil, Poet of Rome]]. Vergil in his rivalry with V1 (mirroring that of Vergil's with Dante) and having several attacks and quotes borrowed from him, and Virgil in his (unintentional and indirect) guiding of V1 through Hell, as V1 constantly encounters traces of Gabriel throughout its descent.

** Heresy: A [[RedAndBlackAndEvilAllOver sinister red and black]] [[PlanetHeck Hellscape]] resembling a [[CreepyCathedral cathedral]] decorated with [[GruesomeGoat goat skulls]], chains, and {{lava pit}}s. This layer is the closest thing the game has to [[FireAndBrimstoneHell a typical depiction of Hell]]. King Sisyphus' Prime Soul is imprisoned in this layer, in the city of Dis, a dark, hellish cityscape where every window is blazing red by the burning souls of the heretics and it constantly rains fire.

** Gluttony: Unlike its poem counterpart, which is described as a realm of icy mud, this game's version of Gluttony is depicted as [[EvilIsVisceral a visceral]] [[WombLevel red realm]] filled to the brim with flesh, teeth, acid, giant stone hands, and [[TheWallsHaveEyes numerous eyes covering the surfaces]], with gaping mouths serving as the layer's doors. This is the first layer that's [[YouDontLookLikeYou depicted completely differently]] from its poem counterpart, [[BloodyBowelsOfHell being a visceral Hellscape]] rather than a slimy snowscape of scum and mud. King Minos' Prime Soul is imprisoned in this layer.

* TakingYouWithMe: They explode upon death, dousing nearby foes in sand and doing a ''lot'' of "hard" damage (temporary max HP reduction) to V1 should they be hit by said explosion.

* RemovedAchillesHeel: Brutal difficulty makes it so they ''don't die when detonating their canister'', which they'd otherwise need an Idol to do. If you see one when this is the case, you'll need to kill the bastard immediately before every enemy gets sanded.

* BewareMyStingerTail: It can fire a harpoon out of its tail. That being said, the harpoon can be parried with a well-timed Feedbacker punch. Should the harpoon hit you, you can punch it out with the Feedbacker.

* TurnsRed: Enrages once it's knocked down to the third of its health, throwing out explosive attacks with greater quantity.

* InstantDeathRadius: Downplayed in the initial build in that you would (probably) not die instantly, but if you got anywhere close to a Guttertank it would cue a lightning-fast haymaker that would launch you into the nearest wall, disorienting you and setting you up for a rocket. Getting in their faces to heal was rarely an option. Guttertanks were even smart enough to wind up a punch if you Whiplash them; by the time the distance closes, it would land. However, this attack was nerfed shortly after Layer 7's release, by way of adding self-inflicted ScratchDamage and a longer recovery animation to the punch during which it can be parried - but ''only'' if it misses.

* InASingleBound: Brutal difficulty gives them the ability to jump towards V1, letting them close distances much faster and making them a more oppressive threat.

* UnneccesaryCombatRoll: They gain the ability to roll around you before shooting on Brutal difficulty, making them ''much'' harder to hit and likely to catch you off-guard.

* ImperialStormtrooperMarksmanshipAcademy: As stated by their terminal entry, Schisms cannot aim precisely due to their malformed anatomy; they instead opt to release Hell Orbs in vertical and horizontal waves in the general direction of their opponents. If V1 were to stand perfectly still, only one Orb from a Schism's vertical wave would be fired directly at them. Both attacks have wide coverage, however, and they subsequently become more dangerous during the chaos of a group skirmish--when it's easier for V1 to run into them if they're focused on another target.

* ShockAndAwe: Between the two phases of his fight, the Ferryman of Wrath perches himself higher up on his ship and summons lightning to strike V1 down. Each bolt is telegraphed by a beam of light highlighting where it is about to appear and the sound of the Ferryman jingling a bell on his oar. Meanwhile, the Ferrymen spawned in the Cybergrind still have access to this attack; they'll exclusively use it whenever it is impossible for them to approach V1 on foot. This can be turned against them; aside from reflecting lightning strikes with a coin, parrying a Ferryman's attacks will generate a (non-damaging to V1) lightning strike right on the Ferryman's positioning, potentially damaging everything around it.

* SnakesAreSexy: King Minos has a snake motif as a reference to his poem counterpart, and not only does he have a handsome appearance, he rules the Lust Layer as TheGoodKing. His muscular Prime Soul is well-built like a bodybuilder, and his arms are coiled by ethereal snakes.

* MeaningfulName: Drones are named after drone music, a technique using single sustained notes or chords. Drones feature heavily in ULTRAKILL's soundtrack for a variety of purposes, from calming ambiance to ominous intensity to atmospheric buildup to overwhelming aural sensation.

* TakingYouWithMe: If killed, it will throw itself at you and explode. You can parry that, too. If killed with an explosion or Piercing Shot, they simply explode on the spot.

* AchillesHeel: A single shot to the gas tank on their back will instantly kill them and cause a huge explosion to boot. This is normally difficult with most weapons since they tend to rush you down, but they're particularly weak to the Marksman as V1 can use it to toss a coin behind them, then shoot it for a guaranteed fatal blow.

The first enemy in the game, an armless and eyeless creature that can only lunge at you with its teeth. Easily dispatched, but comes in great numbers. Debuts in 0-1.

* AstonishinglyAppropriateAppearance: The simplicity of the Filth's design readily communicates its role as the game's most basic enemy, helpless at doing anything except running and biting. Hakita cites this in the Developer Museum entry about the Filth, specifically when comparing its final design to its first, a fully-formed zombie that would later be used as one of the Puppets' models:

* AstonishinglyAppropriateAppearance: The simplicity of the Filth's design readily communicates its place as the game's most basic enemy, helpless at doing anything except running and biting. Hakita cites this in the Developer Museum's entry about the Filth's revision from its original appearance, a fully-formed zombie that would later be used as one of the Puppets' models:

-->"An interesting aspect of the Filth is that, in the early versions of the
demo, people complained about the AI of the melee enemies being too
dumb, but those complaints completely stopped after the redesign. The
new version actually looks like a mindless swarming monster that only
thinks about eating, so it being dumb no longer felt out of place or
like a flaw. Properly messaging the purpose of an enemy or object
through how it looks is an often underappreciated aspect of character
design."

* DiscardAndDraw: In the first encounter with him, he wields a variety of of weapons that he can summon out of thin air, specifically a spear, a greatsword, throwing axes, and swords that he can have spin around him. During the second encounter, he forgoes most of these (aside from the spinning swords) in favor of a single pair of swords. Accordingly, his moveset becomes less versatile, but ''significantly'' more aggressive, no doubt a consequence of his grief-induced rage.
