History Characters / Doom

* RecurringBoss: Though not as often as the Cyberdemon, the Spider Mastermind reappears past the original game's first episode. She reprises the role of FinalBoss in the additional fourth episode, and appears in various ''Doom II'' levels (including one where ''two'' Masterminds appear, as well as another where she teams up with the Cyberdemon).

* HelpfulMook: [[DownplayedExample Downplayed.]] Like the green-haired zombie enemies, these guys drop pistol clips (bullet ammo) when killed. Also, they seem to be prone to monster-infighting do to the combination of inaccuracy and hitscan attacks.
* {{Hitscan}}: They shoot in two-round bursts, unlike the other hitscan enemies (a side-effect of having two frames in their firing animation, unlike the Fallen Human they were coded from.)

* AdaptationalWimp: The SS in ''Wolfenstein 3-D'' were pretty nasty, being EliteMooks that dealt a lot of hitscan damage and took just enough in return to be unpleasant to bring down in groups. In ''Doom'', their fire rates, accuracy, and health take a dive, and they are now almost completely ineffectual. They also replace the common Nazi guards, meaning that you now encounter them in numbers that would have been like walking in front of a firing squad in the original--making it all the more obvious when a single super shotgun blast turns a whole group of them into red jam. For a bonus, the second secret level you encounter them in is almost ''designed'' to result in them infighting with a Cyberdemon, which will usually end in the Cyberdemon killing them all with its rockets.

* BadPeopleAbuseAnimals: Likely the developer's initial motivation to include a severed rabbit head on a pike, before the memes inspired them [[AscendedMeme to retcon it as Doomguy's pet]].

* LeanAndMean: ''Doom 64'' gives Imps a leaner design to make them look more vicious.

* LeanAndMean: The Archvile's body type could be compared to a severely emaciated human.

* PaletteSwap: The Hell Knight is one. Oddly, he uses a separate set of sprites, but is for all other intents and purposes treated as the same entity as the Baron of Hell, just with half the health (500 HP).

* EvilLaugh: [[HellIsThatNoise The way he lets you know]] [[OhCrap how much you are screwed]]. He lets loose a warbling, rising one when spotting you, and emits a... ''strange'' moan when roaming.

* MookMedic: In ''Doom II'', he resurrects fallen enemies.

* DepartmentOfRedundancyDepartment: "Cacodemon" (kakodaimon) is an Ancient Greek word meaning "evil demon", since "daimon" is a word for any kind of supernatural being, malevolent or otherwise. Since ''every'' demon in the world of ''Doom'' is evil, and there's nothing uniquely devious about these fellows, their name isn't terribly meaningful.

* TheGoomba: Your first properly demonic enemy that you encounter, and one you'll see throughout the games. Defensively, they are a bit of a step up from zombies -- in [=MAP01=] of ''Doom II'' for example, you will be solely armed with your pistol until late in the map, and firing 5-15 damage bullets versus 60 HP Imps takes quite a bit more to kill them, compared to the 20-HP zombie grunts. Offensively, their fireballs are slightly stronger than Zombieman's pistol or Sergeant's shotgun, but it's way easier to avoid.

** If ''Doom 64'' lacks this difficulty, Nightmare Imps throw fireballs twice as fast as regular Imps do, and even deal double damage, but they are as frail as their regular counterpart.

* EliteMooks: Nightmare Imps acts like their regular counterpart would in Nightmare mode: they move twice as fast, and their faster and stronger fire power make them more dangerous than normal ones.

->''"What a name. And what a guy. Killing him is almost as bad as letting him live."''
-->-- The Pain Elemental's description in the ''Doom II'' instruction manual

Another floating blob of flesh with a single eye and unpleasant mouth. These guys are brown (unlike Cacodemons, which are red). They can create Lost Souls, which is how they attack.

* AirborneMook: One of the few enemies that are capable of flight.
* ArbitraryWeaponRange: If Doomguy gets right up close to a Pain Elemental, it'll be unable to spit out Lost Souls and will be easy pickings, though it'll still release them on death. Try this in ''Doom 64'', however, and it'll unleash a powerful explosion.
* AsteroidsMonster: They release three more Lost Souls upon death.
* {{Cephalothorax}}: Basically a one-eyed, huge brown floating head.
* {{Cyclops}}: Has only one red eye for vision.
* EliteMooks: Pain Elementals' mobility as floating heads and their ability to create Lost Souls make them elite versions of Cacodemons. They're not more resistant than their red counterpart, though.
* HellIsThatNoise: Pain Elementals' sound effects stand out from the rest in how unique and strange they are. When spotting the player, they emit a garbled sped-up tiger growl, and whenever they are hit they let loose a digitized winding-down [="WAOoowww"=] noise.
* MookMaker: They produce up to 21 Lost Souls one after another, potentially less depending on how many Lost Souls currently exist in the level in total. The ''Doom 64'' version spawns them in pairs for double the pain.
* RedEyesTakeWarning: They're pretty horrifying to look at anyway, but the glowing red eye is an extra bit of warning.
* YouDontLookLikeYou: In ''Doom 64'', they're colored purple instead of brown, their eye is green instead of red, they have two mouths, they have a reptilian tail, and they have uncannily long black flowing hair which can be seen from behind.

A walking skeleton with the ability to fire rockets off its shoulders.

A particularly powerful being that can revive fallen monsters. Also attacks the player with flames that can erupt underneath the target.
