History Characters / Doom2016

* ArmCannon: Each arm on the Cyber variant has been replaced by a huge cannon, which they use to kill anything in their way. The regular Mancubus has organic arm cannons that form naturally. Player straight by both variants in ''Eternal''.

* PoliticalCorrectnessGoneMad: She says it's rude to call TheLegionsOfHell "demons" and that you should call them "mortally challenged." Indeed, even the unambiguously Anti-Demon ARC News agency defaults to this term (at least until the end of the game]].

* EvilIsNotAToy: [[spoiler:The Khan Maykr learns the hard way, [[SpannerInTheWorks in part thanks to the Doom Slayer interfering with the ritual meant to control it]], that bringing the Icon of Sin into Urdak was not the wisest decision that she could have made.]]

** At the start of one of the later levels in ''Eternal'', the Slayer walks through a control room on Phobos filled with UAC employees. Everyone is spooked by his appearance, either looking on in shock or scrambling to get out of his way. One UAC employee has a keycard -- that the Slayer needs to access the inner parts of the facility -- on a lanyard hung around his neck; the Slayer takes the card (while it is still hung around the employee's neck) and uses it on the nearby control panel to open the door, dragging the poor fellow along by his neck in the process. In the next room, the Slayer stares down a UAC Marine -- who briefly adminished him for entering a restricted area before falling silent upon realising who he actually is -- before taking said Marine's plasma gun for his own use. Beyond mild discomfort, the Slayer clearly went out of his way to make sure he did not hurt any of the humans who saw him.
* EternalHero: Whether all the legends you can read in the EncyclopediaExposita are about your player character, or you're just the latest in their line, it seems someone will always rise to swear another eternal RoaringRampageOfRevenge against the forces of Hell.

* CompositeCharacter: The revamped Shield Soldier in ''Eternal'' is what you'd get by throwing the Possessed Security from ''DOOM (2016)'' and the classic Shotgun Sergeant into a blender. They also have a hint of the Chaingunner - specifically, his [[BaldOfEvil baldness.]]

* HelpfulMook: ''Eternal''[='s=] version of the Engineer, the Cueball, will literally just stand around harmlessly until you shoot/punch it, whereupon it will fly into something and then explode with enough force to one-shot even Heavy demons.

* CompositeCharacter: The revamped Shield Soldier in ''Eternal'' is what you'd get by throwing the Possessed Security from ''DOOM (2016)'' and the classic Shotgun Sergeant into a blender.

* BookDumb: Zig-zagged, and ultimately averted. Initially, it's very easy to dismiss him as a rampaging knucklehead who is extremely proficient at killing but clueless when it comes to everything else; however, paying attention to the lore in both games will paint a much deeper picture, giving an explanation to his moments of apparent stupidity or thoughtlessness.
** He completely ignores Hayden's entreaties to preserve the Argent Energy filters, smashing them like an angry gorilla. [[spoiler:He knew well before the UAC ever discovered it just [[HumanResources what Argent Energy was]], and more importantly, [[TheCorruption what it could cause if left unchecked.]] The sequel proves him right on both counts.]]

* NGOSuperPower: Having effectively monopolized the world's energy industry prior to the events of ''2016,'' they have more influence on global affairs than most ''governments'' do. This winds up biting Humanity in the ass when the company is infiltrated by insane cultists.

* EvilInc: Aside from some of the rank and file and the simply amoral members willing to turn a blind eye, it's a company full of cultists that worship Hell and are trying to bring the infernal hordes through to earth in order to claim power and exemption from the torments Hell will inflict on the worlds it dominates.

* BlueAndOrangeMorality: [[BloodKnight A lot of their culture is centred around battles for better or worse]]. Their culture worships strength and bravery, to the point where AsskickingEqualsAuthority and vice versa, MightMakesRight, and their way to deal with prisoners and criminals is to have them fight in a public arena, possibly to the death. And apparently being a stranger counts as a crime. That is even before the corruption set in. Those who survive get to be conscripted into their military to serve under the Maykrs, who don't have the best track record of being morally upright.

* HumanAliens: They hail from the alien world of Argent D'Nur, and yet look indistinguishable from humans both in and out of armour.

* NotQuiteDead: They were believed dead in ''2016'', but some Night Sentinels survived, and are in the employ/service of the Khan Maykr.

The Megacorporation who's research into Argent energy ended up unleashing demons from Hell then later HellOnEarth.

Known also as the "Supreme Maker", the Khan Maykr is the ruler of the Maykr's homeworld, Urdak. She is the main antagonist of ''DOOM Eternal'', and while that fact is clear from her first appearence, her nature and her past with the Doom Slayer are slowly relaled to the player as the game goes on.

Bearing a close resemblance to their ''VideoGame/Doom3'' counterparts, Hell Knights are hulking, yet surprisingly swift bruisers who will turn the Doom Slayer into paste should they get their hands on him.

Known also as the "Supreme Maker", the Khan Maykr is the ruler of the Maykr's homeworld, Urdak. She is the main antagonist of ''DOOM Eternal''.

A silent, unnamed SpaceMarine who awakens laying inside a stone sarcophagus on a UAC base on Mars that has literally gone to Hell. After smashing in a zombie's head with his bare hands and acquiring a suit of PoweredArmor from another nearby coffin, the marine proceeds to butcher his way through an army of demons to put an end to the madness.\\\

* EightiesHair: The Mullet Slayer Skin gives him [[ExactlyWhatItSaysOnTheTin a mullet]] [[ParodiedTrope on top of his helmet.]]
* NinetiesAntiHero: Has [[IHaveManyNames many]] [[DarkAgeOfSuperNames simple, yet gritty names]], NoSocialSkills, [[AxCrazy a penchant for grievous bodily harm, oftentimes using his own bare hands]], [[TheDreaded a threatening presence to both humans and demons alike]], and a simple, yet effective KillEmAll strategy to handling demons and their tech using an [[{{BFG}} oversized]] [[HyperspaceArsenal arsenal]]. He could just as well have been a villain if not for [[UnscrupulousHero his solid moral center]] underneath the anger and, come ''Eternal'', [[TheExtremistWasRight how it's really hard to disagree with his stance on meddling with the demonic]].
* {{Acrofatic}}: Only when the Mullet Slayer Skin's equipped, as while the Doom Slayer has a very obvious beer gut there, [[LightningBruiser he's also just as effective as he would be normally.]]

* AmbiguouslyHuman: Has the outer appearance of a human, understands how to use human-made computer interfaces and weapons without any explanation, but also has strange runes etched on his hands, and doesn't flinch when exposed to demonic energy that turns most people into zombies. His Praetor Suit, which was supposedly forged in hell, has the ''English'' letters and numbers "8623", "D22", "CAUTION" and "1/0 Logistics Manufacture" printed on it. In ''Eternal'', Novik and the Betrayer also call the people of Earth "your people" while talking with the Slayer. Logs found in ''Doom Eternal'' confirm the Doom Slayer is genetically human ([[spoiler:further confirmed by him being Doomguy from the original games]]), but his body is infused with things the UAC cannot identify which give him his increased speed and strength. A {{Flashback}} shows this is something done to him [[spoiler:by the mysterious hooded "Seraphim", one of Khan's right hand angels, during his time with the Sentinels]]. The Khan Maykr notes that he's no longer a mortal, while Hayden refers to him as a Titan much like the Icon of Sin.

* AnthropomorphicPersonification: In ''Doom Eternal'', a UAC scientist trying to figure out what he is gets a crisis of faith, wondering if the Doom Slayer is an agent of God, or some sort of divinity himself. After seeing footage of him singlehandedly overturning hellish hordes that Earth's greatest weapons could do nothing about, and noting how he's [[TheDreaded the only thing the demons truly fear]], she comes to the conclusion that he must be this. Once a man, now the literal embodiment of Doom.

* AttackAttackAttack: His ''entire shtick'' is focused around exactly two things - sheer speed and killing power. If you're not constantly moving and killing, you're going to die; he has absolutely ''zero'' defensive potential other than sheer offense. Properly played, he is the fastest and deadliest thing on the battlefield - but only if you take advantage of his strengths.

* BloodKnight: He's single-mindedly focused on murdering demons, and if the brutality of the [[FinishingMove Glory Kills]] are any indication, he likes fighting. Emphasized in an interview with the ''2016'' Creative Director.

* BreakTheBadass: [[spoiler:How he turns up mentally in the hands of the Night Sentinels after an untold amount of time in Hell. Some combat therapy and being given a reason to gradually stabilize himself went a long ways to restoring his sanity - only to [[DoomedHometown lose everything all over again.]] This time he settled into a permanent ''rage'' instead of breaking again.]]

** [[spoiler:As he is the original Doomguy, he had legitimate, wholehearted fondness for his pet rabbit, Daisy. He even has a framed ''oil painting'' of him holding a rabbit in his Fortress of Doom... [[TragicKeepsake along with an empty cage containing a rabbit's foot]].]]
* CanonCharacterAllAlong: [[spoiler:''Eternal'' explicitly confirms the Doom Slayer is Doomguy from the original games, shown in a {{Flashback}} on Sentinel Prime wearing his iconic helmet. It also implies that the events of ''Doom 3'' somehow fits into his back story, as he has a Soul Cube of his own, as well. He keeps his old armor in the Fortress of Doom]].

** As has has been slated on multiple occassions in statements made by Id Software since ''Doom'' of 2016, [[spoiler: Doomguy is a direct descendant of the Blazkowicz bloodline.]] Now, whether or not that means it's the same as [[spoiler: in the Doom RPG titles, William Josesph "BJ" Blazkowicz III,]] hasn't been stated assuredly, but the family name at least is concrete.
** While it's from an EasterEgg that doubles as a CallBack, [[spoiler:considering all the strides taken to meld every ''Doom'' entry as part of the same universe, [=FLYNNTAGGART=] being the password to unlock ''Doom [=II=]'' ingame suggests that the Doom Slayer might use the name he has in the novels, Flynn Taggart, as an alias]].

* TheComicallySerious: He's silent, incredibly angry and is unbelievably violent. But there is some humor from those aspects of him and what he does, from collecting Doom Guy Dolls, fist bumping one and in ''Eternal'' clearly having no care for personal space. Driven UpToEleven if the player is having him wear the [[SillinessSwitch Doomicorn]] armor, where he still looks permanently pissed-off and strikes powerful poses, but the goofy white-and-pink armor makes him all but unable to be taken seriously.

** His enemies hate and fear this aspect of his personality; see below. Throughout all the countless ages he's been fighting the demonic hordes, he has never once given up nor stopped fighting, even after being trapped alone in Hell for eons on end, losing all of his allies, knowing his actions may potentially doom a civilization to a massive energy crisis, or even just being chained up completely naked to a slab with a zombie coming to bite off his face.

* DoomedHometown: After his allies the Night Sentinels were defeated and their realm Argent D'nur was destroyed, he embarked on a endless war into the bowels of Hell. [[spoiler:With the reveal in ''Eternal'' that he's the classic Doomguy, this also means demons invaded his Earth back in ''Doom II: Hell on Earth'', driving him to eventually remain in Hell to forever battle the forces of Doom at the end of ''64''.]]

** In ''Eternal'', the reaction of the UAC personnel who see him is to recoil in terror. One poor man who has the misfortune of possessing the key the Slayer needs can only lean back in his chair, petrified in fear, and doesn't move as the Slayer grabs the keycard, drags him by the strap to the door lock, and uses it to move on. In the next room, two UAC guards start to challenge the Slayer, but go completely silent as they realize who they're talking to, with the Slayer giving the mouthiest guard a DeathGlare and taking the terrified man's weapon without a word. The base computer also has alarms specifically to warn of the Doom Slayer.

* FunTShirt: The Mullet Slayer Skin makes him wear a shirt that says ''EXTRA THICC''. It's quite apt given [[{{Acrofatic}} what else changes about the Slayer.]]

* HumanAlien: [[spoiler:{{Subverted}} as ''Eternal'' reveals that he's none other than ''[[CanonCharacterAllAlong the]]'' [[CanonCharacterAllAlong Doomguy from the original games]], having been found and taken in by the Night Sentinels after spending an unknown amount of time in Hell following the events of ''64''. Though you could make the arguement that he's an alien due to the fact that he's a human from an alternate earth were the UAC weren't evil cultists and just had the misfortune of their teleportation tech opening portals to hell. This would be a case of DistinctionWithoutDifference as he's still genetically human in spite of being from an alternate earth.]]

* HyperspaceArsenal: The Doom Slayer can carry up to nine guns at once, ranging from the humble combat shotgun to the all-obliterating {{BFG}}-9000, as well as his trusty chainsaw, a variety of grenades, and the almighty Crucible sword. And that's not even mentioning the wide variety of weapon mods which he pulls out of nowhere to swap around at a moment's notice, ranging from a sticky bomb launcher for the combat shotgun to an mobile turret and energy shield attachment for the chaingun. As such, though he appears to be carrying no more than his armor, a single weapon, his equipment launcher, and a BladeBelowTheShoulder, the Doom Slayer has a tool for virtually every type of demonic dilemma Hell throws at him within reach, and he is ''quick'' on the draw. At one point in ''2016'', he even stuffs an entire ''upper torso of a mangled corpse'' into his inventory to bypass a retinal scanner.

* LivingLegend: He's basically become to the Demons what they are to us, being feared in-story and having all the forces of hell either wary at least or outright shitting themselves at the very worst.

* NeverHurtAnInnocent: Doom Slayer despises demons, hell, and anyone collaborating with either. He'll kill anyone that's been corrupted and turned like the Hell Priests or the Mauraders. However, he's trying to save the earth as well and not just kill the demons after all, if he was only concerned with killing the demons he wouldn't go out of his way to [[spoiler:stop the Maykrs from sacrificing the earth.]] He's trying to save humanity while also waging war on hell and any time he interacts with normal people, he may be rude and scare the shit out of them but he won't hurt them.

* PornStache: The Mullet Slayer Skin gives him a rather impressive mustache... [[RuleOfFunny right on top of his helmet.]]

* TooSpicyForYogSothoth: He's gone to Hell multiple times and broke out every time (the ending crawl from the original game even says he's "too tough for Hell to contain") It gets to the point where the demons are [[HorrifyingTheHorror downright scared of him and try hard to keep him OUT of hell.]]

** [[spoiler: However, given that these are the same Night Sentinels who willingly sided with the Khan Maykr even after learning of her pact with hell, it's likely that he doesn't really care if they respect him or not]].

The Megacorporation thats research into Argent energy ended up unleashing demons from hell then later HellOnEarth.
* EvilInc: Aside from some of the rank and file and the simply amoral members willing to turn a blind eye, it's a company full of cultists that worship hell and are trying to bring the infernal hordes through to earth in order to claim power and exemption from the torments hell will inflict on the worlds it dominates.

* AmbiguouslyHuman: Despite his past as a flesh and blood human, there's something ''off'' about both his mannerisms and his speech patterns. Come ''Eternal'' [[spoiler:he has suddenly gained complete knowledge about the Sentinels and the Maykrs, and now calls humanity 'your people' when talking to the Doom Slayer, implying that he doesn't count himself among them. The game also reveals the "Seraphim" who gifted Doomguy great strength and speed sounds exactly like Hayden, and even uses the same lines when empowering the Slayer as when Samuel gave Doomguy his first argent energy cache on Mars. Further, Samuel's robotic body is revealed to be utterly "alien" in design, and it was shown to be sufficiently similar to the Doom Fortress's system in order for him to [[SentientShip transfer his consciousness into it]]. [[ArsonMurderAndJaywalking also,]] He and the Maykrs both refer to their seperate hell energies as Argent Energy, despite having little to no contact with each other directly. Whether this means Samuel was replaced by the Seraphim at some point, or is slowly being [[DemonicPossession possessed]] by him, or something else entirely, is left unclear, however.]]
* AuthorityEqualsAsskicking: Leader of the UAC and doubtlessly its strongest fighter, thanks to his cybernetic body. He's the only person other than the Doom Slayer to survive going to Hell and back. In ''Eternal'', it's revealed that he personally led the forces of humanity in battle wielding the Crucible, though this worked out less than perfectly.

* BadBoss: It's not clear how much of a hand he had in drafting the UAC's more sinister policies on Mars (a seven day workweek, deliberately sacrificing workers to demons simply to acquire better data, etc.), but it's implied that he at least willingly turned a blind eye to it. Even during the Mars outbreak, he is rather cavalier about the deaths of his employees, admitting responsibility but expressing zero remorse, as he deems the UAC's energy extraction WorthIt.

* EvenEvilHasStandards: Not exactly "evil" so much as "morally questionable to a dangerous degree". While initially, he refuses to give up on Argent energy as he sees it as an important resource, regardless of where it comes from, [[spoiler:in ''Eternal'' he learns, or perhaps remembers, that Argent is quite literally the tortured, broken souls of hell's victims, cruelly distilled into refined energy by merging it with the "holy" energy of the Sentinels by the Maykrs. After that, he couldn't suffer it to exist any longer, and codex tabs reveal that he had been trying to research a way to create a synthetic Argent Energy using the Demonic Crucible to remove Earth's connection and dependence to Hell.]]

* InsufferableGenius: He has a very high opinion of his intellect and believes he can harness the powers of hell for the good of humanity without falling to Hell's influence. He's not entirely wrong, but [[TheCorruption unfortunately the rest of the UAC was less resilient.]]

* LaserGuidedKarma: [[spoiler:In the VFR game, he deletes Abraham Peters' consciousness so he doesn't cause anymore "problems". Come Eternal, by the time the Slayer encounters Hayden's remains, he is torn in half with his left arm missing--the exact same kind of damage Peters' corpse sustained in ''Doom 2016'' and ''[=VFR=]''.]]
* LossOfIdentity: It's ambiguous just how much of [[spoiler:the human Hayden is left, and how much of him was subsumed by the Maykr technology he used to build his robotic body. His mannerisms in ''Eternal'' are noticeably different from how he acted in ''2016'', he's undergone a complete 180 on using Argent Energy, and he displays thorough knowledge of some topics that Hayden should have never known about.]]

* MorallyAmbiguousDoctorate: Isn't a full-on cultist like Olivia, but still very interested in exploiting Hell's resources. And while his conflict with Olivia is obvious, one has to wonder if and how much of the UAC Mars branch's cult behavior and development of "battle demons" were allowed to proceed with his knowledge and/or blessing. [[spoiler:He comes back from the brink in the final act of ''Eternal,'' after realizing (or rather revealing) just where Argent [[SoulPoweredEngine actually comes from]], it's too abhorrent for even ''him'' to consider, and he squarely sides with the Slayer insofar as it has to go -- ''all'' of it.]]

* NighInvulnerable: The only other human besides the Doom Slayer to make it back from hell and without a gun to defend himself. Being a cyborg with an energy shield, not much could scratch him.

* NotMeThisTime: You might be quick to assume that Hayden's continued experiments with the Demonic Crucible after the events of ''Doom 16'' were responsible for the invasion of Earth shortly thereafter. Surprisingly, this is not the case; the invasion was a pre-planned event orchestrated by the Khan Maykr and her Hell Priests. In fact, it was one of these priests, Deag Ranak, who drove Olivia Pierce to develop a hell cult on Mars in the first place.

** Furthermore, [[spoiler:Hayden may be literally part Maykr (if not completely); that is, the cybernetic portions of Hayden's brain are implied to be derived from their technology. ARC scientists couldn't figure out how to access his cortex and describe it as "alien", and he was able to transfer himself into the Fortress of Doom's systems (which are of Maykr design) because they have similar digital architecture. Not to mention is thorough knowledge of Nekravol, Urdak, and the history of Argent energy, which a human could not possibly have access to.]]

* ReasonableAuthorityFigure: Relatively speaking, when compared to Olivia and ''especially'' the Khan Maykr. He seems to be the only person in the UAC who realizes how much Olivia has been corrupted by Hell and recognizes that a full-on demonic invasion is not a good thing. If he had recognized the immediate threat Olivia posed to the UAC Mars installation, the initial martian invasion could have been prevented. Furthermore, [[spoiler: after discovering the true nature of [[SouldPoweredEngine Argent Energy]] he forsakes it altogether, and instead turns to developing a synthetic alternative to Argent, all the while leading the ARC against the demonic invasion on Earth.]]

* TeethClenchedTeamwork: With the Doom Slayer. Samuel would really rather that the Doom Slayer ''didn't'' destroy all the machinery that extracts energy from hell, which clashes with the Doom Slayer's view of 'Rip and tear everything and everyone related to hell'.

* ThisIsUnforgivable: [[spoiler:After learning what Argent energy was, even ''he'' was so disgusted he promptly swore it off forever, and promptly starts plotting to kill the Khan Maykr for her absolute selfishness.]]

** Later in ''Eternal'', he shows thinly-veiled resentment at [[spoiler:Khan Maykr and [[PoweredByAForsakenChild her methods in creating Argent energy]], as well as the lengths of her desperation to keep [[AGodIAm her power]] by any means necessary, even allying with Hell and damning countless worlds to oblivion]]. It is a key development that contrasts his own prior behavior that made him almost NotSoDifferent to the [[spoiler:Khan Maykr]].

* UtopiaJustifiesTheMeans: Debated. He spends the whole game justifying the use of Argent energy, despite its hellish origins, because it's a solution to humanity's energy crisis. By the end, [[spoiler:he concedes that the Doom Slayer might be right about destroying all of Hell. But "having an unsolvable energy crisis" is ''not'' an alternative, so he turns on the Doom Slayer at the end]].

->''"I believe in honesty... especially now, in what will be your final moments in this world. All the rumors... the human sacrifices... the Hell portal... the demons... it's all true. My sisters and brothers, be thankful. You will be the first. You will have a seat alongside them as I will in what will become the new world they create for us. Starting now."''

Dr. Olivia Pierce is a high-ranking adherent and researcher in the UAC, and has taken practical control of the UAC Mars Base by causing a Hell Wave of Argent energy while releasing all of the captive demons in the Lazarus Labs, zombifying 64% of the staff and killing the rest. She is a major antagonist of the game, and opposes Dr. Samuel Hayden, whose claimed interests are only in Hell's Argent energy, by trying to bargain with the demons and open a permanent portal to Hell.\\\

Olivia was formerly an ordinary woman, as demonstrated by a picture of her prior appearance which can be found in the Advanced Research Complex on an array of monitors displaying high-ranking UAC researchers. However, her long-term exposure to Hell deteriorated her physical body as it had Samuel's, causing her to develop debilitating scoliosis. In an attempt to remedy this and maintain mobility, she had herself integrated into an artificial exoskeleton. While this worked, the exoskeleton keeps her in a constant state of pain and torment, which, in her ever-increasing fanatic dedication to Hell studies, she refuses to remedy through medication, lest her mind be dulled in any way.

** [[spoiler:Turns out, making deals with the literal demons of hell is likely to give you exactly what you bargained for: You'll get "power beyond comprehension" alright, but it's by transforming into the Spider Mastermind, a massive brain-shaped creature with an arachnid-like mechanical chassis, an Argent plasma gun, and immense telekinetic powers]].

* EvilMakesYouUgly: After triggering [[spoiler:the portal to hell with an Argent reactor, the glimpse we see of her right before she turns into the Spider Mastermind is already a bit zombified.]]

* GamerChick: Implied; she has the second highest score on the UAC leaderboards for Demon Destruction.

* MeaningfulAppearance: [[spoiler:Her becoming the Spider Mastermind is very poetic - she made a DealWithTheDevil for power and godhood, and betrayed her own people just for that. But she didn't really consider how demons in general see humanity ([[TheDreaded save for the Slayer himself]]) as mere ''insects''. Instead of the healthy, all-powerful goddess like she hoped she would be, she became a highly intelligent albeit grotesque, demonic beast whose appearance echoes that of a spider, referring to her sins, and being left by the demons she sided with to be put down like a rabid animal]].

* NotSoWellIntentionedExtremist: She preaches to anyone in the cult she's set up and to anyone who would listen to her that the forces of Hell would allow mankind to advance and evolve. However her codex entry privately discloses that she was either [[TheCorruption so far gone]] or merely blowing hot air to make the masses more pliable to do her bidding and reveals this as a ruse, with her actual goal being to procure godlike power for herself, [[KickTheDog with her last entry to her followers essentially being a cruel screw-you about how they'll suffer in eternal torment, completely forgotten, while she ascends to godhood]].

** At the very beginning of the game, in the hologram recording around the Doom Slayer's coffin. She keeps her composure, but clearly realizes that if what's inside wakes up, she's ''completely hosed''.

* PathOfInspiration: She's turned the UAC from an energy company into a hellish cult with lies and promises of rewards.

* SmugSnake: Although she managed to unleash the demons upon the UAC station, it’s painfully obvious despite her best attempts to pass off her shady activities as scientific work that her superiors knew exactly what she was planning, and excavated the Doom Slayer’s sarcophagus as a countermeasure should she go through with it. She also sincerely thought that her demonic benefactors wouldn’t double cross her the first chance they got. [[spoiler:But by the end of the game, you’ll find out for yourself how ''that'' goes.]]

* VocalEvolution: As TheCorruption is causing not only [[SanitySlippage her mental stability]], but also her physical well-being to gradually worsen over time, it's reflected by her voice becoming increasingly weaker and more frail.

* BenevolentAI: Not only does VEGA -- a sentient AI powered by Hellish energy, and the brain of the UAC facility-turned-Hell-cult -- completely fail to go rogue and try to stop you, he remains calmly cooperative throughout the process of [[spoiler:walking you through ''killing him''. In ''Eternal'', VEGA becomes the Doom Slayer's MissionControl, helping him to keep the Fortress of Doom running, providing intel, and teleporting the Doom Slayer to the places he needs to be.]]

* {{Foreshadowing}}: ''DOOM (2016)'' notes that "it is rumored that VEGA's core is powered by a piece of arcane technology found near the Argent Fracture." Come ''Eternal'' [[spoiler:it's revealed he is in fact the lost [[DeusEstMachina A.I. god]] of the Maykrs.]]

The protagonist of ''Doom VFR''. A scientist for the UAC who had been protected from the initial wave of demonic energy that Olivia unleashed, only to be torn apart by a Pinky after stepping off an elevator. However, a top secret UAC protocol caused his consciousness to be digitized, allowing him to download himself into a combat-ready chassis and get to work containing the demonic presence.

* PoliticalCorrectnessGoneMad: She says it's rude to call TheLegionsOfHell "demons" and that you should call them "mortally challenged." Indeed, even the unambiguously Anti-Demon ARC News agency defaults to this term.

* TheQuisling: She's not shy about playing favorites for the demons.
* {{Understatement}}: When the Doom Slayer arrives on Earth to destroy the Super Gore Nest, she remarks to potential passers by that "you might notice a slight change in the environment." You're immediately treated to a ruined city filled with lava, giant tentacles, and MeatMoss.
* VillainousBreakdown: Finally snaps when the Doom Slayer is closing in on the Icon Of Sin, screaming out of desperation and frustration to the demons present to kill him.

An alien realm populated by HumanAliens with access to a powerful and abundant energy source, who founded the Slayer, wounded and injured, and nurse him back to good health. They were invaded by Hell and taken over, shortly after a civil war and an unexpected betrayal.

* ChekhovsGun: Gives it to you, in the form of a handheld device he tosses at you before you leave with what you came for. He hints that you will need it to grant [[CameBackWrong his son]]'s heart peace at last... [[spoiler:it turns out to be literal, as the heart means his ''actual'' heart, and the device is a ritual switchblade-esque knife; plunging it into the Icon's heart is vital to finally derailing the Khan's ritual]].

* OldSoldier: Has the appearance of a grizzled man in his late fifties, with white hair and a slight droop. He's still quite buff for his age, however. Doubly so when you remember he's not fifty something, but several millennias old since he's been in Hell since before the Slayer's entombment.

* AsskickingEqualsAuthority: They were big on this; the most capable warrior in their ranks was naturally seen as the most fit to lead. [[spoiler:This naturally means that Doomguy became their king by default, until he kills Deag Grav.]]

* BlueAndOrangeMorality: [[BloodKnight A lot of their culture is centered around battles for better or worse]]. Their culture worships strength and bravery, to the point where AsskickingEqualsAuthority and vice versa, MightMakesRight, and their way to deal with prisoners and criminals is to have them fight in a public arena, possibly to the death. And apparently being a stranger counts as a crime. That is even before the corruption set in. Those who survive get to be conscripted into their military to serve under the Maykrs, who don't have the best track record of being morally upright.
* ChurchMilitant: They definitely look the part, resembling an order of knights with their armors and being in service of an supposedly celestial power.

* FallenHero: A heroic faction of demon-hunting warriors that fought alongside the Slayer in early times; they spread to many planets, and built a prosperous interstellar civilization. [[spoiler:Ultimately, they were fractured by a schism over whether to overthrow the Khan Maykr or stay loyal to her, even after the [[HumanResources true nature of Argent Energy was revealed.]] The rebels, led by the Slayer, would have won if not for the Betrayer; by ''Eternal'', the ones that remain are fully in cohorts with the Khan Maykr and Hell Priests whom orchestrated their downfall and dependence on them, becoming little more than servants of their will.]]

* HonorBeforeReason: Their culture and code of honor logically led to this. [[spoiler:It ultimately led to their downfall; even the realizations that Argent Energy was made from their fallen brothers and sisters, and that they were being manipulated and betrayed at the highest levels, were not enough to convince all of them to turn against the Khan Maykr.]]

* ProudWarriorRaceGuy: In general, their culture was strongly reminiscent of the Norse, with a high emphasis placed on honor, combat prowess, and AsskickingEqualsAuthority. They had a WarriorHeaven, and even the lowest members of their society were able to rise to greatness through sheer guts and combat prowess.

* BadassBoast: While he may chastise the Doom Slayer for going against the current order by going after the Hell Priests, all of whom are still considered Sentinels because of their bloodline, he holds a high opinion of him as evident by his words in the beginning of ''Eternal.''

* ComicBookFantasyCasting: His face is modeled after the late [[Music/{{Motorhead}} Lemmy Kilmister]], even sharing the same distinct boils on their face.

* EnemyCivilWar: Codex entries refer to a few that happened during their first age, for example the Hell Knight were serving an entity known as the Great Serpent until its defeat and they became gladiators. Even in game they they fight each other when there is nothing else to do.
* EvilIsVisceral: Their Hell is a cross between FireAndBrimstoneHell and full-on Creator/HieronymusBosch "river-of-blood" fleshy Hell. Most of their environments and structures are made from entrails and corpses, and some demons are even crudely grafted with cybernetics, interwoven with their guts.
* MadeOfIron: Many of the larger or higher-level demons can easily shrug off explosives and energy blasts, and will keep on fighting, even if they are reduced to a skeleton.

* ZergRush: While Hell's ruling class (such as the Hell Priests and the Nameless One) employ deceit and manipulation to subvert the defenses of realms and worlds marked for conquest, most of the actual battle tactics used by Hell's armies basically boil down to "overwhelming the enemy with hundreds of thousands of bloodthirsty monsters".

** The Zombies of ''Eternal'' don't look quite as disgustingly inhuman, with two exception; the Cueball, which is even more grotesque than its Engineer precedessor, and the Mecha Zombie, which has various cybernetic bits poking out all over its body, as well as what look to be exposed intestines.

* HumanoidAbomination: Former human beings that were exposed to demonic energy, transforming them into deformed feral monstrosities, with the Unwilling and ''2016''[='s=] Possessed Scientists in particular appearing barely human.

* OurZombiesAreDifferent: The Possessed in ''2016'' are former UAC staff that were killed and then resurrected by Argent Energy as a result of the Lazarus Wave, while the Unwilling are the partially demonic remnants of cultures defeated and assimilated by Hell over eons. The Zombies are ''Eternal'' are stated to be those who have been "corrupted and decieved" by Hell's power to become "mindless, grotesque contortions of their former selves".

* TookALevelInBadass: Mecha Zombies can take more damage than Possessed Soldiers and has an arm cannon that doubles as both a plasma blaster for ranged attacks and a flamethrower for close range attacks. Their walking speed is still pretty slow, however.

* UndergroundMonkey: Even the most basic Possessed/Zombie comes in a number of varieties, ranging from former UAC scientists and workers, to unfortunate citizens of Earth, to even ancient undead (referred to as "the Unwilling" in ''2016'') who are the remnants of alien civilizations conquered and absorbed by TheLegionsOfHell.

* BodyHorror: In ''2016'', their armor and guns look to have been ''fused'' into their flesh.
* ChargedAttack: Regular Soldiers can charge up their plasma rifle to fire a slow-moving shot that explodes after traveling a short distance.

* ShieldBearingMook: Possessed Security/Shield Soldiers are a variant who carry a HardLight tower shield that [[LuckilyMyShieldWillProtectMe protects their front]] and is capable of [[AttackReflector reflecting ballistic slugs and bullets]] right back at the player. The shield can be damaged through sustained fire (indicated by its color changing from blue to teal to red), but all it takes to return it to full strength is a one-second move on the wielder's part, which means you're all but forced to outmanoeuvre them if you can't bring explosive or plasma ordnance to bear against them.

* AscendedFanon: "Pinky" originated as a FanNickname, as their official name of "Demon" was often [[DepartmentOfRedundancyDepartment confusing]]. InUniverse, the term "Pinky" was coined by UAC expedition soldiers, the nickname sticking because researchers couldn't find any direct references to the creatures in demonic texts.

* DeathSeeker: ''Eternal'' gives this as an explanation to their ActionBomb tendencies. [[AndIMustScream Driven to madness by the circumstances leading to their undeath]], the vestiges of humanities that Lost Souls still cling onto compel them to mindlessly attack whatever they come across, so that hopefully it could grant them their {{Final Death}}s. The Doom Slayer is only too happy to oblige.

* AchillesHeel: In ''Eternal,'' they are very tough and hard to stagger, and both of their attacks can easily kill the Slayer in one or two hits, making them a massive threat at any range. However, they can be instantly opened to a finisher by shooting a grenade into their mouths.

* AchillesHeel: In ''Eternal'', they are hideously tanky, even by the standards of their fellow heavyweight demons; their arm cannons let them function as an anti aircraft cannon, keeping you from moving too freely around the arena. However, if you blast their arm-cannons with the Precision Bolt or enough rounds from the Plasma Rifle, they can only fire pathetic fireballs that don't explode. They also lose their devastating close-range flamethrower attack, leaving them easy to kite.
** The Cyber Mancubus naturally amps both of these attributes up to eleven, but in return, has an even more easily-exploited weakness; a single Blood Punch will tear off ''all'' of their armor and most of their HP, exposing their huge guts to retaliation.

* ArmCannon: Each arm on the Cyber variant has been replaced by a huge cannon, which they use to kill anything in their way. The regular Mancubus has organic arm cannons that form naturally.

* {{Cyborg}}: The Cyber-Mancubi, as is in their name, who have been enhanced with UAC technology such new weapons replacing their organic flamethrowers and armour plating grafted to their flesh. This has become standard for regular Mancubi in ''Eternal'', and their redesign explained in their codex as the UAC Cultists having done man-made cybernetic modifications to improve upon their fighting power and armor without going to the extent of the Cyber-Mancubi.

* DoubleJump: In ''Eternal'', they are capable of this move in Battlemode, though as a trade off, they won't be able to shoot until they land again.

* {{Kevlard}}: Mancubi are the beefiest demons in Battlemode HP-wise, which is understandable considering their significant girth. That is not to say they're MadeOfIron, however, their increased HP simply allow them to stand against the Slayer for a bit longer than the smaller demons, not tanking rockets and Ballista shots all day.
* MadeOfPlasticine: If you have a Blood Punch loaded in ''Eternal'', you can run up to a Cyber-Mancubus and punch it once to break through all of its armor in a single shot, making the rest of the fight a lot shorter (in fact it's probably weaker than a regular Mancubus once its armor is down).
* MightyGlacier: They fill this role on the battlefield. They can withstand more punishment than almost any other non-boss enemy, and their damage output can be frightening, but they are some of the most formulaic enemies in the game, making them both predictable and easy to outrun.
* NonIndicativeName: Rather than being the SpearCounterpart to succubi, they're heavily associated with Gluttony. They're {{Fat Bastard}}s with twin {{Arm Cannon}}s that spew fireballs (or globs of HollywoodAcid in regards to the Cyber-Mancubus), not HornyDevils.
* OrganicTechnology: The Mancubi have organic {{Arm Cannon}}s. Inverted with the Cyber-Mancubi, who use cybernetic cannons akin to the "old school" Mancubi, and averted completely with the design of both variants in ''VideoGame/DoomEternal'', being directly based on the classic Mancubus appearance (with Cyber-Mancubi featuring more drastic cybernetic augmentations).

* TruerToTheText: As seen above, Mancubi are given the most dramatic redesign of the demons in ''Eternal'', ditching the chitinous cyclops appearance of ''2016'' for the classic "fat ogre" form, with cybernetic arm cannons instead of OrganicTechnology. Cyber-Mancubi follow suit, distinguished by the greater degree of cybernetic enhancements applied to the rest of their bodies.

* BigRedDevil: Just like his classic counterpart, the ''2016'' version is a big red demon with horns and hooves. The Fireborne Barons play with this a bit; it loses the red coloring, until you damage it enough to reveal its bright burning insides.

* GroundWave: In ''2016''[='s=] multiplayer, the Baron of Hell loses his ability to throw fireballs, but can pound the ground to launch a row of rock spikes in front of him.

* LightningBruiser: Despite their massive bulk, the Barons are pretty damn swift and agile, even if an attentive Slayer can still outmaneuver them. Taken to its extreme in ''Eternal'', where they are even tankier, but have lost none of their agility.

* TruerToTheText: {{Subverted}}. ''Eternal'' introduces the Fireborne Barons who come from a Baron clan of [[MagmaMan Magma Men]], who have an obsidian carapace, natural flaming armblades, and are basically embodiments of Hellfire itself.

* EnemySummoner: ExactlyWhatItSaysOnTheTin. It summons demons to help out in the battlefield.

* SuspiciouslySimilarSubstitute: It essentially served as ''2016'''s version of the Archvile before being PutOnABus for ''Eternal'' in favor of bringing back the Archvile. Allegedly, in early versions of the game the Summoner was originally going to actually BE the Archvile, but the name was changed before release for unknown reasons.

Swift and agile Imp-like demons who are expert hunters and ambushers. While in ''2016'' they only appear in the multiplayer as a playable demon, they return as enemies in ''DOOM Eternal''[='s=] campaign.

* EliteMook: Despite their Imp-like appearance, they're classified as a "Heavy" demon in ''Eternal''. While both species employ similarly evasive combat tactics, Prowlers are far stronger and tougher (requiring three pips of fuel to kill with a chainsaw), have a SpreadShot attack for when you're mid-distance, and can teleport all over the place.

* FragileSpeedster: They have just a little bit more health than Imps, but their teleportion powers (as well as their ability to climb and swing like ComicBook/SpiderMan in the multiplayer) makes them perhaps the most agile demons in Hell's armies.

* GlassCannon: Played straight in ''DOOM 2016'', where if you get can get a bead on one, it'll go down pretty easily, but if it gets up close to you, ''all'' of its attacks are {{One Hit Kill}}s. Zigzagged in ''Eternal''; in the upper difficulties they can occasionally survive a point-blank super shotgun blast (where as Imps still get [[ChunkySalsaRule salsa]] [[LudicrousGibs chunked]]), but they are still the weakest of the Heavy-class demons.

* MonstrousMandibles: They have a tripartite jaw line, with the lower jaw opening vertically as well as horizontally.

* OhCrap: One of its ''Eternal'' Glory Kills plays this in hilariously realistic fashion. Doomguy slices its arm off with the Doomblade, and for the second or so before he finishes it off, it can only stand there screaming in fear and pain at the wound.

A demon similar in appearance to the Summoner which only appears in the multiplayer game. It was added in the first expansion pack, "Unto the Evil". It uses vampiric plasma lightning beams to steal the lifeforce from its victims and then convert it into hellish energy projectiles.

* SpreadShot: After using its lifedrain lightning to fill up its meter, it can then launch a spread of five large plasma shots similar to the BFG, each with the capacity to one-shot other players.

* AirborneMook: They make good use of their wings in combat, hovering high in the air to rain down acid from relative safety. The Codex also mentions that the Gargoyles were a real pain for the Night Sentinels to deal with, as their ability to fly meant that they could easily bypass city defenses and snatch up unsuspecting civilians.

* BodyHorror: A closer look at the Gargoyle reveals that their arm scythes don't look to be a natural part of their anatomy, instead seeming to be misshapen metal blades crudely grafted in their forearms, bisecting their hands. All that gore coating the Gargoyle's arms is probably as much from them as it is from their victims.

[[folder:Dread Knight]]
!!!Dread Knight
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/dread_knight_9.png]]

Hell Knights that are enhanced with various cybernetics .

* AchillesHeel: They aren't quite as fast as their unmodified counterparts are, and their tendency to launch ranged attacks means that they will often be left behind by both their fellow demons and the Slayer as the battle moves around the arena. They're also susceptible to MoreDakka, courtesy of the Chaingun.
* BladeBelowTheShoulder: Has a LaserBlade attached to each wrist.
* {{Cyborg}}: While functionally similar to Hell Knights, Dread Knights stand in stark visual contrast as their flesh has been meshed with cybernetics, with their arms in particular being replaced by ArtificialLimbs equipped with energy blades.
* EliteMooks: Are far stronger than the standard [[SmashMook Hell Knights]], forming a bridging point between them and the Barons of Hell. They also lose some of their predecessor's weaknesses - they gain both a ranged attack and a wide-reaching sweeping slash that covers a large radius around them, making kiting them a hazardous proposition. Their leaps even create pools of electrified plasma that can still damage you and restrict your movement, even if they miss.
* MoreDakka: Their weakness, as is handily demonstrated by [[NewWeaponTargetRange dropping you into a small arena with one right after obtaining the chaingun]]. Two seconds of concentrated rapid fire will bring it down.
* ShockwaveStomp: Its leaping stomp attack as been upgraded to unleash red lightning in a wide area around itself, creating a floor hazard that damages anyone who goes over it.
* SuperSoldier: They are essentially Hell's version of this: they are faster, tougher and stronger than normal Hell Knights, juiced up with massive doses of epinephrine (in layman's term, adrenaline) for every kill they get, making them even more eager to disregard their lives for the sake of battle.
* SwordBeam: They can throw these at you with their arm blades if they can't catch you.

!!!Arachnotron
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/arachnotron.png]]

Giant, brain-shaped demons fused to a spider-shaped cybernetic frame, they come equipped with a plasma turret and a pair of grenade launchers.

[[folder:Pain Elemental]]
!!!Pain Elemental
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/pain_elemental.png]]

Powerful, floating one-eyed demons that can launch multiple Lost Souls.

* AchillesHeel: They're slower and larger than their fellow flying heavies, Cacodemons; they also lack their devastatingly powerful bite, and their projectiles can be shot down, unlike the lightning balls the Caco spits.
* BarrierWarrior: In Battlemode, where it can summon a Soul Shield made up of Lost Souls to not only protect itself against attacks, but launch at the Doom Slayer.
* TheBusCameBack: After being absent from the franchise since ''Doom 64'' (released in 1997), they're back for ''VideoGame/DoomEternal''.
* {{Cyclops}}: Only has one big red eye in the middle of its giant head, or say, body.
* EliteMook: Serves as an upgraded, tougher version of the Cacodemon. However, the same tactics to stagger a Cacodemon (launching a grenade or Sticky Bomb into its mouth) will not work on Pain Elementals.
* EyeScream: All the Glory Kills on them involve the Doom Slayer doing something horrible to their eye, with one involving the Slayer stabbing up through their upper jaw and impaling their eye with such force that it goes straight out of their head.
* FastballSpecial: Sometimes, a Pain Elemental will just grab one of its Lost Souls and straight up chuck it at you.
* FateWorseThanDeath: The Pain Elementals are said to be abhorrent beasts from the depths of the Umbral Plains, cursed to eternally forge Lost Souls in their gut, which causes them such excruciating, everlasting pain that the only way they can relieve it is to kill indiscriminately and spread suffering.
* GrumpyOldMan: Was designed to look as if it had such a disposition. Given its codex entry, it has every right to be a bit surly.
* MagicMissileStorm: Its main form of attack is launching Lost Souls at you.
* MonstrousMandibles: Has two jaws and no less than ''8'' toothy mandibles. Its "Big Mouth" emote displays its huge, horrendous maw as it roars.
* MookMaker: Played with; besides a melee swipe for self-defense, its attacks all involve summoning Lost Souls. However, unlike in classic ''Doom'', these Lost Souls function more like projectiles rather than enemies with independent AI.
* WaddlingHead: Played with. Since it's a giant demonic head that floats around rather than walks, it doesn't have feet, but instead has two stubby little arms, which it uses to [[https://78.media.tumblr.com/f33ae80cb3154875985e260040642e56/tumblr_pd99swUIeg1qh1rfpo1_500.gif pantomime various motions that make it look like it's stomping through the air towards you]], as a tongue-in-cheek reference to their [[https://78.media.tumblr.com/ae3a96bb1672cf1f1441fd20b9a60ae4/tumblr_inline_p8y7iqnppj1s408j9_400.gif animations from the original game]], which look like the Pain Elemental is walking with invisible legs.

[[folder:Archvile]]
!!!Archvile
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/arch_vile.jpg]]

High-ranking demons with the power to control flames and summon and empower fellow demons.

* AchillesHeel: Their strongest attacks require them to stay in place, and teleportation notwithstanding, they are incredibly slow compared to their fellow demons. If you can close to quarters with them, the Slayer's absurd damage output lets him obliterate them into kibble within moments.
* AdaptationalWimp: Compared to their original iteration, the new Archviles have lost some of the power that made them so painful to fight in the original ''[[VideoGame/{{Doom}} Doom II]]''. Not that they are any easier to deal with, though, but still:
** For starters, their fire attacks, while still very damaging, are nowhere near as deadly as they used to be. Originally, an Archvile's flame attack has a pretty long range (896 units, further if you damage him and he retaliates), is only limited to his line-of-sight, and deals a ''lot'' of damage (20 for the initial zap that launches you upwards, and ''70'' for the ensuing explosion. Given that you're a lot more vulnerable back then, this is often life-threatening), on top of flinging you into the air when it connects, making engagements risky without ample cover. Now, the thing seems to prefer staying in the background and can only deal the bulk of its damage up close.
** Secondly, it can no longer spam its revival ability, whereas the original Archvile checks for a valid corpse ''every time its sprite frame changes'' and resurrects it, thus potentially creating an unending wave of fresh demons to fight you. In fact, this power has been completely removed in exchange for turning the Archvile into an EnemySummoner and mobile buff totem, which is still an absolute pain in the ass, but much less of a resource drain on you due to the new gameplay changes making it easier to gain health and ammo back.
* AreaOfEffect: If you stay too close to an Archvile, it will turn the area around itself into a sea of flames. Like in the original games, it can also instantly turn the Slayer's current location into a raging inferno, though this time, the attack can be avoided by simply moving away from the spot in question. In Battlemode, this ability is called "Lake of Fire" and can be summoned to any location the Archvile player's crosshair is pointing at.
* ArrogantKungFuGuy: In the Phobos reveal trailer, he reacts to the Doom Slayer not with fear or blind rage, but as if he were called in to do pest control rather than kill the guy who makes Hell bend down to its knees.
* AssKickingPose: Will raise its flaming hands into the air, Randy Orton style, when summoning fire, [[CallBack much like in the original games]].
* AuthorityEqualsAsskicking: Is stated by its codex entry to be among Hell's royalty, and is one of the most powerful demons on the roster.
* DeployableCover: Can produce a flaming shield that's impervious to attacks (unless you Blood Punch it) and impassable by the Slayer; while in the campaign the Archvile has to stand still to maintain its shield, in Battlemode it can simply deploy the shield and move on (or through it).
* EliteMooks: Serves as the upgraded replacement of the Summoner in ''Eternal''.
* EnemySummoner: If left alone in Campaign, it will continuously summon waves of new enemies. It can even summon its fellow ''Super Heavies'' given enough time.
* GroundWave: Its primary attack at mid-close range in the campaign is to launch fast-moving waves of flame along the ground.
* LargeAndInCharge: Archviles descend from the oldest race of demons and with their superior intellect and pyschomancy they are natural rulers of Hell's savage forces. They also tower over most other demons that aren't Super-Heavy types.
* MookDebutCutscene: Subverted. Despite pre-release footage showing the Archvile making a dramatic entrance on Phobos, in the actual game it first appears in Taras Nabad with so little fanfare that that you might not even notice it's there until you see other demons being buffed or summoned.
* MoreTeethThanTheOsmondFamily: Has a mouthful of jagged, pointy teeth.
* OhCrap: Archviles are among the demons that are most blatantly afraid when you Glory Kill them, shrieking in clear terror or trying to get away from the Doom Slayer before he finishes them.
* PlayingWithFire: Its abilities are primarily flame-based.
* SecretAIMoves: Player-controlled Archviles do not use a firewave attack like in the single-player, nor do they function as walking Buff Totems (outside of an attack boost ability available to all player-controlled demons).
* ShockAndAwe: The Archvile also possessed a few lightning powers in pre-release multiplayer gameplay. This did not make it into the final build.
* SquishyWizard: Subverted; the Archvile may be a caster, but it is ''far'' from squishy. While it is less beefy than the other Super Heavies, it still has a considerable amount of health, so much so that it can sometimes tank a ''BFG'' shot, ''point-blank''. Played straight in Battlemode, however.
* TeleFrag: Faltering an Archvile while it's trying to summon will make it botch the process, instantly gibbing the would-be summons.
* TeleportSpam: It possesses the ability to teleport, though at least in Battlemode, this is restricted to anywhere in its line-of-sight as long as the path isn't obstructed.
* TookALevelInBadass: While Archviles were always a nightmare to deal with in earlier titles, the ''Doom Eternal'' incarnation of the infamous demon boasts a whole suite of new powers, ranging from covering the ground around itself in flame, barely flinches even if bombarded with rockets, to teleporting around and giving significant power boosts to any demon in its vicinity.
* TurningRed: Not the Archvile itself, but it does this to all the enemies in the area whenever it's around, casting a StatusBuff that turns enemies red and on fire, and more importantly increases their health and damage. It even increase their resistance to the Doom Slayer's [[OneHitKill Chainsaw]], requiring more fuel to use it against them unless you find and kill the Archvile.

[[folder:Carcass]]
!!!Carcass
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/carcass.png]]

Cybernetically-augmented human corpses that have fallen victim to the demonic forces.

* AchillesHeel: Their shields are vulnerable to the same overcharging effects as the Riot Soldier's, and its' explosion when destroyed is much bigger; this means that they often [[StopHelpingMe endanger their allies FAR more than they help them.]]
* ArtificialZombie: They are human carcasses that are reanimated and fitted with cybernetics, just like the Revenants.
* BarrierWarrior: The Carcass can erect a wall of plasma energy that will block the Doom Slayer's shots against itself or other demons, primarily as a deterrent against the rocket launcher, as well as just blocking the path of the Slayer himself. It can do this from all the way across an arena, but the projection leaves a trail of electricity that leads to its location.
* BodyHorror: Bloated, rotting upper bodies of human corpses, merged with the machinery that once again brings them life and unceremoniously attached to a three-legged cybernetic chassis.
* {{Cyborg}}: The lower half of its body is completely mechanical, and even the upper half has been augmented with cybernetics.
* FatBastard: Its upper torso is stuffed with cybernetics and bloated with decomposition, giving it a corpulent appearance.
* FightingClown: Despite its grotesque appearance, it gets characterized as one. It flails about for its melee attacks, jumps and scampers around to avoid direct conflict, and its ranged attack involves using waves generated from its torso while it essentially jams out to the music.
* GroundWave: It can fire its shield cannon into the ground to launch a short-ranged shockwave at the Slayer.
* SpiderLimbs: The human-like upper body of the Carcass is stuck to three cybernetic legs.
* SpinAttack: Its melee attack involves it spinning its upper body around while sticking out its arms.

Female snake-like demons with cybernetic augmentations that wields a pair of bladed whips.

[[folder:Marauder]]
!!!Marauder
!!!'''Voiced by:''' Edward Bosco

[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/marauder.png]]

->''"You were never one of us. You were nothing but a usurper. A false idol. My eyes have been opened. Let me help you to see, Slayer."''
\\
Former Night Sentinels who remained loyal to Khan Maykr despite her consorting with Hell. Resurrected by Hell, they serve as the antithesis to the Doom Slayer.

* AchillesHeel: He's fast, tanky, and hits like a runaway freight train, but he has exploitable weaknesses just like every other demon. While he can block any direct damage thrown his way, he can't do a thing about splash damage; plastering the area around him with grenades will rapidly blow away large portions of his health. He can't summon wolves unless he blocks damage with his shield, either. Finally, he can be chain-staggered by efficient usage of the Slayer's massive arsenal of {{BFG}}s, allowing him to either be killed in one hit (see Alpha Strike below) or left nearly dead.
* AlphaStrike: The fastest way to kill a Marauder (without using the BFG) is to bait out his attack, then hit him with ''[[TheresNoKillLikeOverkill absolutely everything]]'' in your arsenal while he is staggered, keeping him off balance with a series of explosions, shotgun blasts and rockets. Keeping him off-balance is critical to this strategy, as once he regains his composure, his shield will negate any damage you can throw at him and you'll be getting a super shotgun blast to the face for being at the range necessary to pull this off.

* BossInMooksClothing: Technically, not even the first Marauder fought at the end of ''ARC Complex'' is a boss, given his lack of a health indicator of any kind. Nonetheless, these guys are the absolute bane of players on ''any'' difficulty level, so much so that they ''transcend'' EliteMooks, with a single Marauder being enough to make your blood boil, even on ''I'm Too Young To Die''. The game will teach you to hate them with a passion.

* ChessMotifs: WordOfGod describes the Marauder as equivalent to the Queen on the chessboard, being the one piece with unparalleled mobility and game ending potential that requires an extraordinary amount of your attention on the battlefield, and who creates an absolute ''ton'' of openings for the other, less maneuverable pieces while you are distracted trying to deal with it.

* CycleOfHurting: A skilled player can keep them perpetually stunlocked by swapping between the Ballista and Super Shotgun after each shot, while spamming grenades.
* DefiantToTheEnd: One Glory Kill has the Marauder PunchCatch the Doom Slayer’s fist instead of just letting himself get killed. Unfortunately it’s the arm that also has the Doomblade on it so he ends up stabbed through the face for his trouble instead. They are also one of the few type of demon who don't scream in pain or fear during any glory kill, at best glaring when the Doom Slayer is about to take their head off with their own axe.
* EvilCounterpart: Serves as a corrupted version of the Doom Slayer, with a similar build, similar armor, and equivalents of some of the marine's weapons, as well as moving just as fast as him.

* FakeUltimateHero: {{Invoked}} against the Slayer, calling him nothing but "a usurper" and "false idol".

* {{Foil}}: To the Doom Slayer. He has a similar kit, but unlike the Slayer, who is all about offense, the Marauder is described as a "defensive powerhouse." He wields an invulnerable Argent shield that allows him to NoSell most forms of damage, and his preferred strategy is to take advantage of this to get in close so he can chop the Slayer up, tanking any return fire instead of avoiding it.

* KungFuProofMook: They are notably resistant to many of your equipment and super weapons. The chainsaw doesn't do anything to Marauders regardless of fuel capacity, and trying to OneHitKill them using the [[{{BFS}} Crucible]] is so difficult to set up that you are much better just fighting them conventionally. Additionally, shots from the BFG-9000 will bounce right off their shield and not deal any damage, and they can't be slowed down using Ice Bombs. However, the Flame Belch still works on them if you can time it right, and a BFG blast will still one-shot them if they've been staggered with another weapon first.
* LaserBlade: Uses a double-sided axe whose blades are made out of pure hell energy.

* ShotgunsAreJustBetter: Uses a super shotgun like the Doom Slayer, though it doesn't have the grappling hook.

* TacticalSuicideBoss: The Marauder is ''only'' open to a direct counterattack when he swings his axe. If he just stuck to tossing axe beams, firing his shotgun, and summoning wolves, he'd be almost completely immune to direct fire. Downplayed because he'd still be susceptible to splash damage from explosives.

* ContinuityNod: The codex lists the Tyrant's weakness as being their slow turn speed. In other words they are weak against circle strafing. That is exactly how you deal with cyberdemons back in the original ''VideoGame/{{Doom}}''.

* MoreDakka: Tyrants have no weaknesses, and a loading screen tip will helpfully tell you that [[MythologyGag to defeat a Tyrant]], [[CaptainObvious shoot it untill it dies]].

* SuspiciouslySimilarSubstitute: Serves as this to the Cyberdemon, only having a different name due to "Cyberdemon" referring to one specific demon in the ''2016'' universe.

* TruerToTheText: Unlike the ''2016'' version, the Tyrant is more or less a modern recreation of the classic Cyberdemon, down to the boatloads of cybernetics (right leg, left arm, abdomen), facial appearance (long curving black horns, beady eyes set apart, razor-sharp teeth, lack of a nose) and color palette, though it [[CompositeCharacter retains]] the ''2016'' Cyberdemon's ArmCannon design and a good portion of its attacks. Reflecting the classic Cyberdemon's degradation from Episode 2s final boss to a rare MiniBoss in Doom 2, Tyrants are presented as EliteMooks or mini-bosses instead of the full on Boss encounter that the ''2016'' Cyberdemon was.

** There's a bug in the game, where, if you freezes a Tyrant with an ice bomb while he is firing the laser, then once unfreezes, [[ThisIsGonnaSuck he will fire the beam indefinitely]].

* KilledMidSentence: [[spoiler:All three of them. They either boast about how they're supposedly indestructible, or try to bargain with the Doom Slayer. It doesn't work.]]

* TheQuisling: While the Khan Maykr is the ultimate leader of what remains of the Sentinel Worlds, the Hell Priests seem to do most of the actual ruling. Deag Grav in particular is described as lording over the populace of Sentinel Prime, while Deag Ranak was placed in direct charge of the UAC after Olivia Pierce's death, directing cultist efforts to aid the forces of Hell.
* SmugSnake: Deag Grav moreso than the rest of them, especially [[spoiler:after the boss battle on Sentinel Prime, [[TooDumbToLive where he has the gall to try and boast]] to the Slayer immediately after he slays his guardian about his blood pact that, if broken, will have all of Urdak and the Sentinels try to kill him. [[YourHeadAsplode The Slayer blows off his head anyway before he can finish boasting]].]]
* SquishyWizard: They are immensely powerful summoners, responsible for orchestrating not only the fall of Argent D'Nur, but are leading the invasion of Earth [[spoiler:at the behest of the [[ManBehindTheMan Khan Maykr]]]], but once the Slayer reaches any of them, he effortlessly kills them before they can either cast something noteworthy or monologue his ears off.

[[folder:In General]]
!!The Maykrs

* {{Cyborg}}: The drones are the most obvious but the Maykrs have used cybernetic enhancements as well as use of Argent to improve their body.

* DyingRace: Their creator has been missing for an untold number of time, and things have gone FromBadToWorse since as their numbers has dwindled and their leader has gone insane and can't be replaced via their usual means anymore. Only a constant stream of Argent Energy siphoned off from the demons' slaughter of other worlds keeps their world alive. [[spoiler:The Doom Slayer slaughters most of the remaining Maykrs and seemingly brings final destruction on their world. Some dialogue suggests that he may have inadvertantly returned their missing creator in the process, so maybe they have a future after all.]]

* LightIsNotGood: They have gold-plated, silvery white themes to their architecture and bodies, and only care for their own realm's prosperity and the "believers" who are sent to Urdak.
* MeaningfulName: "Maykr" is pronounced the same as "Maker," and they are vaguely godlike beings worshiped by the Argenta.

* NoBiologicalSex: There doesn't seem to be any features that distinguishes male from female Maykrs, aside from the Khan Maykr, who appears to have something resembling breasts and a feminine voice.

* ResurrectiveImmortality: They have a type of this. The Maykrs of old were incredibly long lived, but they would eventually undergo a form of physical and mental degradation. They got past this with a process known as "Transfiguration", where they will willingly die and then be resurrected anew, being no worse for wear. However, [[HaveYouSeenMyGod after the Father went missing]], the Maykrs were left unable to perform the Transfiguration, which eventually led to the Khan Maykr making the deal with Hell for Argent Energy, which stalls their degradation indefinitely instead.

* CombatTentacles: For melee they sprout two golden energy tentacles from the sockets on their shoulders to whip at you.
* EliteMook: The boss fight with Khan Maykr has her accompanied by Drones coloured red instead of silvery-white, and they have a bit more health than the normal varient.
* HeavilyArmoredMook: The Maykr Drones are classified as "fodder" demons (along with imps and zombies), but unlike other demons of the same class, their bodies are heavily armored, making body shots do much less damage, however, a headshot will quickly dispatch them. Tellingly, they're also the only fodder type enemy that require a fully fueled chainsaw to cut down.
* PinataEnemy: Scoring a headshot will make them drop a payload of health, armor and ammunition. Bonus points for the various ammo and powerup drops being ColorCodedForYourConvenience, so that they even look rather like a spray of confetti/candy.

* CyberCyclops: Their cybernetic armor makes them look like they have a single glowing eye in the middle of their face.

* HolyHalo: Has a technological variant (referred to as an "Orator Ring") attached to the back of their armor, which serves as a status symbol.

* StaffOfAuthority: Higher ranked Maykrs who carry golden staffs, unlike the lower ranked Maykr Drones.

* TheChessmaster: His stealing of the Father led to the Khan Maykr [[spoiler:making a deal with Hell and made Argent Energy prosperous throughout both their realms]]. He also manipulated the Doom Slayer ever since the Unholy Wars, ensuring that the Maykrs would become the Doom Slayer's enemy due to allying with the Demons and the Slayer would have the strength to defeat them through the Divinity machine he used on him. [[spoiler:And if true that he and Samuel Hayden are one in the same, then he also manipulated the Doom Slayer to defeat Olivia Pierce's cult and the Demons on Mars, and to retrieve for him the demonic Crucible from Hell, allowing him to continue his Argent research and production and his plans to synthesis man-made, synthetic Argent Energy. All of which during an [[PostPeakOil energy crisis on Earth]] that caused him to be looked by humanity as a legendary Saviour with his technology]]. What he ultimately is scheming towards is unknown, only that he seems to want the Demons and Maykrs out of his way.

* DishingOutDirt: When resurrected in hell, it gains the ability to create rock walls to trap the player and heavily restrict movement.

Formerly Agaddon Hunters, an ancient beast-like race that were bred and modified by Hell specifically to hunt the Doom Slayer and the Night Sentinels. After they were supposedly driven extinct long ago, they have been revived as heavily armed cyborgs to continue their task.

* BarrierWarrior: It can generate a plasma shield around its organic body that needs to be taken down via Plasma Rifle before damage can be dealt to its body. It will regenerate if you don't destroy the Doom Hunter's sled fast enough.

* ClippedWingAngel: Once you do enough damage to it, it's forced to abandon its sled, which disables its force field, missile, and machine gun attacks.
* ContractualBossImmunity: The first three Doom Hunters you face have an immunity to being frozen by Ice Bombs, with subsequent Doom Hunters losing that immunity.

* ShedArmorGainSpeed: Enough damage to a Doom Hunter will cause it to abandon its sled, sacrificing firepower and defense for a massive increase in agility.
* SuperSoldier: Doom Hunters were a once-thought extinct species from Earth that were captured and genetically modified by by Hell into mindless cyborgs to specifically combat and hunt the Doom Slayer and the Night Sentinels. They've only gotten stronger after Deag Ranak rebuilt them.

* {{Ultraterrestrials}}: The Aggaddon Hunters are native to ''Earth'' according to DNA analysis, with Carbon-dating on some preserved subjects measuring them as nearly ''eighty million'' years old and pre-dating all complex, carbon-based life on Earth. The Argenta discovered them sixty million years ago, and no fossils of the species has been found beyond the Arctic tundra.
* WeCanRebuildHim: Deag Ranak brought the species back and gave them the arsenal of a tank division as upgrade.

* NoSell: As a boss, he is immune to most of your equipment and superweapons. The Flame Belch doesn't generate armor when used on him, the Chainsaw doesn't register him as a valid target, and Freeze Grenades don't take effect. He also can't be instant-killed by the Crucible if the player tries to pull this on him when replaying the mission (it will still take out a massive chunk of his health), though the BFG and Unmaykr still work on him.

* AngelicAbomination: She ''looks'' like a divine, heavenly being with her predominantly white color palette and holy intentions, but from what we have seen of her, [[spoiler:and what she looks like underneath the armor (at least after the release of [[TheCorruption the Icon of Sin]])]], she is anything ''but'' truly angelic.

* CallingYourAttacks: Everytime she uses her "rain of fire" attack, she says a word that [[{{Mondegreen}} sounds like "circle" or "servile", but is probably just gibberish.]]

* {{Foil}}: Like Samuel Hayden, she's a bio-mechanical Supreme Leader who decided long ago that it would be a good idea to harness the power of Hell to bring prosperity to her planet. She's a great deal more arrogant about it than Hayden, and was actually quite a lot more successful than he was at doing so, at least for a while.
* GodGuise: She appeared as a benevolent, godlike figure to the Argenta and countless other worlds, offering spiritual salvation to a heavenly plane -- [[spoiler:but underneath her armor she's just another monstrous-looking alien. Not even the sufficiently advanced technology of the Maykrs is strictly hers; it was all granted to them by a higher power, the Father.]]

* SatanicArchetype: Ruler of a race of [[LightIsNotGood decidedly misanthropic]] angelic figures who [[spoiler:usurped control after the original, good ruler of Urdak left for unknown reasons, and has been corrupted into a demon.]]

* ArmorAsHitPoints: Until you knock all of its armor plates off its body, you will not be able to do any damage to its fleshy bits.

* BookEnds: In ''Doom II'', you kill this guy by shooting its brain. In ''Eternal'', after destroying its armor and then its body, you kill it once more by planting the Crucible right into its brain.

* CameBackWrong: The Betrayer stuck a deal with Hell to bring his dead son back to life, only for him to come back as an infernal, towering elder demon instead of a man, because the demons see this as a fitting reward for a traitor like the Betrayer.

* {{Determinator}}: Even the flesh is being blasted off its body, it will relentlessly fight back with no loss in vigor until its health is at zero.

* EvilCounterpart: To the Doom Slayer. It uses a giant suit of powered armor just like his, and is easily the only thing that's remotely in his weight class. Both of them were once ordinary men changed by supernatural powers into unstoppable forces--the difference being that the Doom Slayer still has his humanity and sanity, while the Icon is a nearly mindless force of destruction.

* MightyGlacier: It's every bit as slow moving as you would expect given its massive size. It hits as hard as you expect as well, and take a massive amount of damage to put down.

* ThinkingUpPortals: Can apparently create portals at will. It uses one to invade Earth once it's awakened in Urdak, and later summons another one to flee after the Doom Slayer strips its armor off, forcing the Slayer to jump in after it.
* TookALevelInBadass: The last time we saw it in ''Doom II: Hell On Earth'', it was little more than a head on a wall, with its only defensive and offensive capabilities revolving around spawning monsters, and only taking three hits from a rocket launcher to put down. Here, it's a giant, demonic HumanoidAbomination who not only can still spawn monsters, but possesses a plethora of direct attacks that can easily kill the Doom Slayer if he lets himself get hit. To make things worse, it's also monumentally tougher to kill, [[RasputinianDeath as the Doom Slayer has to destroy its armor, shred its body with gunfire until it's basically a skeleton with a couple meat chunks still hanging on, and then impale its exposed brain with the Crucible]] (which happens to be literally the only viable method of putting it down). [[spoiler:And that still only puts it out of commission instead of killing it.]]

* CallingYourAttacks: When unmasked, it can be seen speaking some type of demonic language before deploying attacks such as raining fireballs.

* MonstrousMandibles: Has two jaws and no less than ''8'' toothy mandibles. It's "Big Mouth" emote displays its huge, horrendous maw as it roars.

* MonstrousMandibles: Has two jaws and no less than ''six'' toothy mandibles. It's "Big Mouth" emote displays its huge, horrendous maw as it roars.

* TacticalSuicideBoss: The Marauder is ''only'' open to a direct counterattack when he swings his axe. If he just stuck to tossing axe beams, firing his shotgun, and summoning wolves, he'd be almost completely immune to direct fire. Downplayed because he'd still be suspectable to splash damage from explosives.

** Not only that, she even let [[OneManArmy the Slayer]], who she was supposed to be fully aware of his destruction capacity, know that [[spoiler: she was going to wake the Icon of Sin!]] She really gave her all to earn this, didn't she?
