In the Doom franchise, a monster is any artificially intelligent thing that is not spawned if the -nomonsters parameter is used. In single player and cooperative games, much of a user's playing time is spent in combat with enemy monsters. Monsters are either placed in a level during its design, created by another monster (particularly, the Pain Elemental spawns Lost Souls), or spawned by the final boss.
Any monster placed in a level or created by the final boss is initially dormant and becomes active only when it sees a player, when it sustains a damaging attack, or when it hears a player attack, even if this is with the (otherwise silent) fist. When activated, a monster will advance on its target and attack, sensing the location of the thing they are after even if it is out of sight, and advancing toward that location even if it is on the other side of the level. If a monster hits an obstruction during its hunt for its target, it will attempt to walk around it or float around/over it (Cacodemon, Lost Soul and/or Pain Elemental). Monsters that have been alerted normally remain active indefinitely, even after respawning or being resurrected by an Arch-vile. However, there is a bug which returns any active monsters to a dormant state if the user re-loads a saved game. In general, monsters of different types can accidentally hurt each other and will often turn against each other in such cases, engaging in monster infighting. If a monster defeats an aggressor without ever seeing or hearing a player, it will return to a dormant state.
Monsters can use some types of teleporters, although they do so accidentally or unintentionally, as their intelligence is very limited. Monsters can similarly activate lifts and open certain doors, although some monsters may not fit through doors and openings that are just large enough for the player. Monsters can be hurt and killed by crushing ceilings, but are unaffected by all forms of damaging floors.
The monsters can be classified into two groups: the former humans, or zombies, possessed by demonic forces, and the demonic monsters (demons, hellspawn, or mortally challenged) originating in Hell or arriving from there.
Classic Doom games
- Zombieman - Once a marine or guard like the protagonist, now a green-haired, Hell-possessed soldier carrying a rifle. The weakest of the enemies in Doom and therefore, the easiest to kill.
- Shotgun Guy - A bald, more durable zombie in black armor with a shotgun. A bit tougher than the Zombieman (perhaps due to his rank), but still very easy to gun down.
- Imp - A brown, human-sized humanoid demon that throws round fireballs and claws nearby opponents.
- Demon (Pinky) - About the size of a gorilla, this muscular pink brute runs quickly on its two hind legs to bite opponents. While not an immediate threat on their own, when in groups they do have a tendency to try and outflank their targets.
- Spectre - Identical to the Demon (Pinky), except that it is partially invisible.
- Lost Soul - A floating, flaming skull that can rush quickly to gore an opponent.
- Cacodemon - A large flying head-like monster with red scales, horns, and one eye. It moves relatively slowly, but has strong jaws and spits out "lightning balls" from a distance.
- Baron of Hell - Two of these act as the boss in Knee-Deep in the Dead, resembling large blood red Satyrs. It can hurl streaming balls of green plasma and employs a powerful clawing attack at close range. They can take enormous punishment before being slain.
- Cyberdemon - The massive boss in The Shores of Hell, a monstrous humanoid cyborg as tall as two men that can absorb more damage than any other monster and moves at a relatively rapid rate for its size, pausing only to fire rockets from its mechanical arm at anything foolish enough to oppose it.
- Spider Mastermind - The cybernetic boss in Inferno and Thy Flesh Consumed. It appears as an enormous brain with eyes, a mouth, and comparatively small arms, atop a four-legged metal chassis with an incorporated triple-strength chaingun which will mow down the unwary to bits within moments.
- Heavy Weapon Dude - A tough, corpulent zombie with darker skin, red armor and carries a chaingun.
- Revenant - A tall, skeletal demon wearing silver body armor that can launch ballistic or guided missiles, and punch opponents when at close quarters. These are the results of recycled demon combatants.
- Hell Knight - Identical to the Baron of Hell but tanned in color, emits higher-pitched sounds and endures only half as much damage.
- Arch-vile - Infernal High Priest who can resurrect dead monsters. It can also conjure flames to attack.
- Arachnotron - Strongly resembles the Spiderdemon, but is much smaller, and shoots greenish plasma instead of super-chaingun rounds.
- Mancubus - A grotesquely bloated humanoid with flamethrowers instead of forearms. It moves slowly, but takes a fair amount of ordinance to bring down.
- Pain Elemental - A large flying head resembling a brown Cacodemon with small arms. It attacks by spitting Lost Souls at its target, and even creates a few more as it dies.
- Icon of Sin - Though not technically a monster, it does still represent one of the protagonist's opponents. The principal one, to be exact, that must be defeated to win the game.
- Wolfenstein SS - Populates the two Wolfenstein-themed secret levels and attacks with a medium-strength machine gun.
- Commander Keen - A hanged effigy of the cosmonaut from id Software's pioneering series of games only appearing in MAP32: Grosse. It neither moves nor attacks, although killing all four Keen figures is necessary to reveal the exit switch and finish the level.
Newer Doom franchise games
The newer games of the Doom franchise generally include a set of monsters from the PC Doom games or inspired on them and possibly a number of new creations. Various ports include the same sprites as their predecessors, although some change their appearances either to achieve a new style (such as in Doom 64) and the newer games (such as Doom 3) provide polygonal versions that suit their more advanced technology and rendering capabilities.
Doom RPG features almost all of the monsters from Doom II, with the exception of the Shotgun Guy, Spectre, Arachnotron, Wolfenstein SS, Commander Keen and Spiderdemon (as well as the final boss).
Returning Monsters(with variants):
- Zombie Private - Zombie Pvt is the first version of the Zombie class encountered in Doom RPG.
- Troop - Troops are the least powerful of the Commando class in Doom RPG.

Non-boss enemies in Doom RPG are organized into classes. For example, there are three types of Imps, while the Hell Knight and Baron of Hell both belong to the "Baron" class. Monsters in the same class use the same sprites, but are somewhat differently colored and vary in difficulty.
Doom II RPG
The Doom RPG sequel Doom II RPG has almost the same enemy entity set as Doom RPG, but adds a few of its own, even adding a few boss entities. The game adds the following new enemy types:
- Lesser Sawcubus - The L Sawcubus is a monster found in Doom RPG belonging to a demonic class known as Sawcubus species.
- Brier - The Brier is a monster found in Doom RPG belonging to a demonic class known as Sentinal species.

- VIOS - VIOS (Virtual Icon Of Sin), is an AI of demonic origins and the main antagonist of Doom II RPG.
In addition to the new classes of enemies, the game has two new boss class entities; the Pinkinator and VIOS. All the sprite artwork used for the enemies was hand-drawn specifically for this game--even for "classic" monsters returning from previous games in the series--in order to allow for higher-resolution sprites than what was used in the original Doom games (though the higher-resolution sprites are only used on higher-end devices).
The official port of Doom to this platform removes the Arch-vile but includes an additional monster over the PC versions.
- Nightmare Spectre - Nightmare Spectres are dark cyan-tinted, faster and more powerful forms of Spectres.
Doom 64 includes newly illustrated versions of the Doom and Doom II monsters, created from high-poly rendered models rather than sculptures or hand-drawings. Revenant, Heavy Weapon Dude, Arch-vile, Spiderdemon, Wolfenstein SS, Commander Keen and final boss are not present.
- Zombieman - They are made from systematically altered dead carnage remade back into corrupted living tissue. The mutations were devastating. The demons have returned stronger and more vicious than before.
- Shotgun Guy - Much like the Zombiemen, he was once a marine, always a marine... Except in this case.... These guys may look like your old buddies the Zombiemen.
- Imp - This Imp heaves balls of fire down your throat and takes several bullets to die.
- Lost Soul - These variations of the Lost Souls look somewhat different, in their new mutations they have become slightly transparent, and there is fire only on the top of their skulls
- Demon (Pinky) - Sorta liked shaved gorillas, except with horns, big heads and lots of teeth. They don't kill easily. Get to close and they'll rip your sorry head off.
- Spectre - In Doom 64, inactive spectres are initially rendered as opaque Demons with a green tint, becoming translucent upon detecting the player.
- Cacodemon - It underwent major mutations, becoming beige-brown, with a single yellow-green eye, and gaining two arms with broken chains attached, and a rather terrifying face.
- Pain Elemental - With further altering from mutations it is colored dark pink (like the original Cacodemon while the Doom 64 Cacodemon was colored beige brown and had two arms), has a green eye and in place of its arms are two mouths so it can now spawn two Lost Souls at the same time.
- Arachnotron - This left them considerably altered; the mechanical body is much bigger, with the brain head ducked down inside the machine itself instead of sitting atop it.
- Mancubus - Their pupil-less eyes have blue sclera instead of green, their bodies have less fat and a more bear-like face, they are taller and wear a metal body harness. Their fireballs are smaller and appear more like fiery brimstone.
- Hell Knight - Though overall similar to the standard hell knight, the mutated variant found in Doom 64 is less pale in color.
- Baron of Hell - It's mutations have given it a red-orange colour scheme (rather than greenish which is instead used for the Hell Knight).
- Cyberdemon - It has not gone through many changes and mutations except that it has darker colored skin, a more bovine-esque head structure (though the face is very canine-like appearance), is slightly stronger and much larger, with thicker wiring running along its robotic body parts.
- Nightmare Imp - The Nightmare Imp is a translucent blue/purple Imp which is faster than the standard Imp variant
- Mother Demon - The Mother Demon appears as a large demonic larva with dead black eyes with red irises, four arms, a skull-like face and smallish mouth filled with many long, sharp teeth. It has no wings, yet moves by floating around.

- Buff Totem - A new threat which continually summons empowered demons until it is tracked down and destroyed. The Buff Totem is completely immobile and must be destroyed with a melee attack.
- Cueball - Similar to the Possessed Engineers from Doom (2016), the Cueball will simply stand in place and will become an explosive missile when damaged.
- Tentacle - Tentacles can be found on certain levels. When approached, they will emerge from holes in the ground and damage the player. However, not all Tentacle holes contain a Tentacle.
- Zombie - Returning from previous games, the Zombies behave similarly to the Possessed from Doom (2016).
- Mecha Zombie - These Zombies appear as red eyed skeletal versions of regular Zombies but utilises multiple mechanical implants and an inbuilt flamethrower/plasma blaster.

- Soldier (Shield)
- Unwilling - The Unwilling are back as normal enemies in Doom Eternal, and their bone armor is sleeker and almost covers the body head to toe.
- Imp - Returning virtually unchanged from Doom (2016), Imps make up one of the main fight forces of the demonic invasion.
- Gargoyle - The Gargoyle behaves similarly to the Imp, albeit with the ability to fly.
- Lost Soul - Lost Souls are much rarer than in previous games, with them now almost exclusively being spawned by the Pain Elemental. Other than this, they behave as in Doom (2016).
- Maykr Drone - The only non-boss Maykr enemies in the game, they have highly resistant bodies but can be easily dispatched with headshots. They were originally Fodder enemies.
- Prowler - Transitioning from the multiplayer mode of Doom (2016) into the campaign of Doom Eternal, the Prowler is like a bigger, stronger, teleporting Imp.
- Revenant - The Revenant's shoulder-mounted rocket launchers can now be destroyed, preventing it from using its ranged attacks.
- Whiplash - A new female demon with a snake-like lower body. The Whiplash is quick-moving and uses a combination of melee and ranged attacks.
- Carcass - This deceptively tanky demon has the ability to summon shields which are similar to those of the shield Soldier.

- Spectre - The Spectre is identical to the Pinky, albeit with the added advantage of invisibility.
- Cacodemon - The Cacodemon of Doom Eternal seems to have received a health buff from Doom (2016), however it can be easily staggered for a Glory Kill if a grenade is fired into its mouth.
- Hell Knight - The Hell Knight returns from Doom (2016), albeit with a tweaked visual design and a more aggressive attack pattern.
- Dread Knight - This variant of the Hell Knight is a faster, tough and all around meaner variation with twin arm-blades. It is able to use a number of area-of-effect and ranged attacks not available to the Hell Knight.
- Arachnotron - Returning from Doom II, the Arachnotron is an agile and tough early-game demon. It has an automatic cannon on its back which can be destroyed with enough damage, or a single direct Sticky Bomb.
- Pain Elemental - Returns from the classic Doom games. As before, it summons Lost Souls as its main form of attack.

- Baron of Hell - Returning from Doom (2016) with an entirely new design, the Baron of Hell is an aggressive and powerful enemy which can attack with a combination of ranged and melee attacks.
- Arch-vile - The Arch-vile returns from the classic Doom games. In Doom Eternal, it behaves similarly to a Buff Totem by summoning and empowering demons for the Slayer to fight. This version of the Arch-vile can also summon a shield to protect itself from the front.
- Doom Hunter - This surprisingly-agile demon is first encountered as a boss in the early game. The Doom Hunter has an energy shield which protects it from incoming damage and a hover-sled which must be destroyed before it can be killed.
- Marauder - The Marauder is a powerful new demon type which uses an energy shield. He can only be damaged when performing a melee attack with his axe, shortly after his eyes flash green.
- Tyrant - The Tyrant is the biggest and toughest of the standard demons. It resembles and behaves like a classic Cyberdemon.
- The Gladiator - A large shield-wielding boss with a two-stage boss fight. His shield mechanics behave similarly to the Marauder.
- Khan Maykr - The leader of the Maykr race. She has a shield which must be depleted before she can be damaged with a Blood Punch.
- Icon of Sin - An enormous monster, the Icon of Sin is a rather straightforward fight which simply needs to have its body parts destroyed to defeat it.
Doom Eternal: The Ancient Gods
Other games based on the Doom engine
Games powered by a modification of the Doom engine include a particular set of monsters suiting their setting, style and game behavior.
