Monsters group

In the Doom franchise, a monster is any artificially intelligent entity 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[]


Doom and its retail extension, The Ultimate Doom, include the following monsters:

  • Zombieman - A former soldier who is now a demonically possessed zombie, armed with a rifle. The weakest of the enemies in Doom and therefore, the easiest to kill. This monster along with the shotgun guy were never named and in Doom (2016) were replaced with The Possessed and The Unwilling
  • Shotgun Guy - A former sergeant ranked soldier who is now a demonically possessed zombie, armed with a shotgun. They are more dangerous and skilled than their Zombieman counterpart.
  • Imp - A brown, human-sized humanoid demon that hurls fireballs from a distance and claws nearby opponents. They are the most frequently encountered monsters.
  • Demon (Pinky) - A large humanoid, bipedal demon with a large mouth, armed with sharp teeth. While only limited to melee, they can outrun their prey most of the time, and can occasionally come in packs.
  • Spectre - Identical to the Demon (Pinky), except that it is partially invisible.
  • Lost Soul - A floating, flaming skull that can rush quickly to bite their opponent.
  • Cacodemon - A large red floating spherical monster with horns, one eye, and a Cheshire cat smile. It moves relatively slowly, but has strong jaws and spits out lightning balls from a distance.
  • Baron of Hell - Two of these monsters 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 - This massive cybernetic minotaur appears as a boss in The Shores of Hell. It will fire a volley of three explosive rockets from the rocket launcher mounted on it's left arm, while moving at a relatively rapid rate for its size. It can easily lay waste on even the toughest mortal who has the guts to challenge it, while being able to easily withstand most attacks from it's high health.
  • Spider Mastermind - This cybernetic boss awaits 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.

Doom II[]

Doom II (and Final Doom) includes the same monsters as Doom in addition to the following monsters:

  • Heavy Weapon Dude - A tough, corpulent zombie with darker skin and red armor, he will rapid fire with his chaingun to quickly perforate his targets.
  • Revenant - A tall, armored human skeleton-like demon that can launch guided missiles and punch opponents 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 conjure flames to attack. Even worse, it can also resurrect dead monsters.
  • Arachnotron - Strongly resembles the Spiderdemon, but is much smaller and weaker and is armed with a plasma gun that fires green bursts.
  • Mancubus - A grotesquely bloated humanoid whose forearms are replaced with a pair of flamethrowers. It moves slowly, but nonetheless possesses potent attacks from it's flamethrowers while withstanding a fair amount of ordinance to bring down.
  • Pain Elemental - A large floating spherical monster that resembles a Cacodemon, except being brown in color and has small arms. It attacks by spitting Lost Souls at its target, and even creates a few more as it dies.
  • Icon of Sin - A giant demonic entity that takes the appearance of a biomechanical goat mounted on a wall, with an exposed brain which shoots cubes that spawn the lesser demons. Though not technically a monster, it acts as the de facto leader of all the other monsters, in which the protagonist must defeat to win the game.

Cameo enemies:

  • Wolfenstein SS - A Nazi Schutzstaffel trooper in blue uniform. Found exclusively in the two Wolfenstein-themed secret levels and attacks with a medium-strength machine gun.

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.

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.
    • Greater Sawcubus - The G Sawcubus is a monster found in Doom RPG belonging to a demonic class known as Sawcubus species.

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).

Sony PlayStation[]

The official port of Doom to this platform removes the Arch-vile but includes an additional monster over the PC versions.

Doom 64[]

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.

Returning Monsters:

  • 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.

New Monsters:

  • 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.

Doom 3[]

Doom 3 includes its own versions of many monsters from the original games. Some of them, such as the Revenant and the Mancubus, are more faithful from their predecessors while others like the Cacodemon and the Commando are considerably different in terms of appearance and behavior.

Returning monsters:

  • Zombie - Former UAC civilians now possessed by evil spirits, they slowly close in to claw their victims, though they can occasionally wield wrenches and flashlights as clubs to deal more damage

  • Lost Soul - A small flying demon consisting of a human head mounted on a flying rocket engine contraption. They come in swarms and will charge right at their target.
  • Cacodemon - A large airborne demon that fires a giant missile at a distance, while biting their victims at close range.

  • Mancubus - A very large, fat demon with fireball launchers for each arm, it alternates by firing one fireball from one of it's launchers before firing the second one. They will also resort to using all their strength to smash their victims up close with their launchers, making them tough, powerful, but nonetheless, slow.
  • Zombie Commando - Former human Marines who were transformed into demonic warriors. Aggressive and intelligent, they can easily overcome their foe with both strength and skill.
    • Tentacle Commando - Possesses a large whip-like tentacle on its right arm, they run at an alarming speed to strike their victims with their tentacle arm, while resorting to kicking and punching.

  • Guardian of Hell - This crocodilian-like demon stands more than 15 feet tall, and will ground pound to summon large 8 balls in it's vicinity while summoning its Seekers.
    • Seeker - Small floating creatures that emit a tiny headlight, acting as spotters for the blind Guardian of Hell to seek their target. Appearing in a group of three, destroying them will leave the Guardian vulnerable.
  • Sabaoth - Sergeant Kelly's final state of his demonic transformation, where his lower half has been replaced with a tank-like vehicle, and upper half being a twisted body attached to heavy machinery armed with a very sharp claw. He relies on the BFG he has looted from Campbell while using his sharp claw to brutally strike his victims.
  • Cyberdemon - A large minotaur-like giant with a rocket launcher mounted on it's right arm, guarding the final portal to Hell in the Caverns. It will either fire three rockets at it's victims, or brutally stomp them to death with it's cybernetic feet. Dubbed as "Hell's mightiest warrior", it can only be defeated by the Soul Cube.

Some concepts of monsters, one of which resembles the spider-like monsters from Doom and Doom II, were shown by id Software during development of the game but did not make it to the finished product.

Doom 3: Resurrection of Evil[]

All the monsters in Doom 3 appear in Resurrection of Evil, except the Sabaoth, Vagary, Cyberdemon, Guardian, Seeker, and Lost Soul. Additionally, some new monsters are included:

  • Bio-Suit Zombie - A Zombie that wears a yellow hazmat suit and a oxygen tank, only found in toxic radioactive areas that can pose a hazard to breathing. Behaves like regular Zombies but drops valuable oxygen tanks upon death.
  • Vulgar - A medium size quadruped demon with a monkey-like frame that primarily shoots green fireballs while resorting to leaping and clawing up close. Behaves very similar to Imps, except possessing much quicker attacks, at the expense of being weaker.
  • Forgotten One - Flying flaming skulls with two demon horns, it resembles the classic Lost Soul more than does its namesake.
  • Bruiser - A tall demon with a large muscular body in the vein of a Hell Knight and mechanical features of a Mancubus. It attacks by quickly firing a barrage of fireballs from it's twin flame launchers

Boss monsters:

  • Hell Hunter - A trio of demons resembling a bulky Hell Knight with some differing physical characteristics. Each possesses unique abilities that are synonymous to the powerups that the Artifact can utilize.

    • Invulnerability Hunter - Possesses a larger body structure than a Hell Knight, and has a bulging, extremely muscular body, and coated with an electrical shielding powered by four generators in it's vicinity, making them impervious to damage. Destroying any of the four generators will dissipate their aura momentarily, making them vulnerable.
  • Maledict - The demonic reincarnation of Dr. Malcolm Betruger, whose head and neck is attached to the tongue of a giant skeletal wyvern-like demon. He can summon giant pillars of flames while summoning Forgotten Ones and throwing flaming meteorites from the air.

Doom (2016)[]

The Doom reboot features a lot of returning monsters from the previous three games.

Doom Eternal[]

Doom Eternal features several returning monsters, along with a selection of new ones. In this game, they are split into one of five categories: ambient, fodder, heavy, super-heavy and boss monsters.


  • 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 - The Soldier comes in two variants which resemble the Possessed Soldier and Security from Doom (2016):
    • Soldier (Blaster)
    • Soldier (Shield)
  • 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 - Base by Original 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 - Human Based Synthetic, This deceptively tanky demon has the ability to summon shields which are similar to those of the shield Soldier.
  • Pinky - The classic Pinky returns in Doom Eternal with behaviour much the same to Doom (2016).
  • 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 and Enhanced Version 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, Spider Mastermind's Genetic Material Based Synthetic Clone, 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.
  • Mancubus - In Doom Eternal, the twin arm cannons of the Mancubus serve as weak points. By destroying them, its attack patterns will be changed and the demon will be weaker overall.
  • Cyber-Mancubus - Returning from Doom (2016), the Cyber-Mancubus differs from the normal Mancubus in that its twin arm cannons can't be destroyed. This demon's armor can, however, be destroyed in a single Blood Punch.

Super Heavy[]

  • 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 - Agaddon Hunter Based Synthetic, 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.

Boss monsters[]

  • 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[]




Super Heavy[]

Boss monsters[]

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. These monsters share various basic characteristics of the Doom game monsters but may show some differences, such as being capable of multiple types of ranged attacks or being subject to the additional possibilities of game scripting (namely ACS in Hexen).
