List of enemies in Doom

The following are enemies in the id Software first-person shooter computer and video games Doom, The Ultimate Doom, Doom II and Final Doom. Most of these enemies also make appearances in Doom 64 and Doom RPG. Most of the enemies in the games are Demons from Hell; otherwise they are possessed, undead humans. Many of these creatures have become iconic in computer gaming. In the Doom novels written by Daffydd Ab Hugh and Brad Linaweaver, the creatures are initially thought to be demons, but are later revealed to be an alien race bent on the conquest of Earth. (Although this is only in the novels, and as such is not canon.)
Zombies
Zombies are undead soldiers who have been turned into brain-dead killing machines by the demons. They are the only non-demonic enemies in the game as well as the only ones who drop ammunition (half the ammo of a fresh clip or a weapon pick-up) when killed (the dropped ammunition, however, can be lost if a door or crushing ceiling comes down on it). Owing to their usage of bullet weapons, zombies can be easily tricked into engaging in monster infighting with other creatures as well as their own kind.
Former humans and sergeants will close the distance on their foe, and then circle, pausing every few steps to fire a shot. Commandos, however, once within line of sight of their foe, will continuously fire their chaingun, only rotating to adjust to their target's movements. Moving out of their line of sight, such as hiding behind a wall or using a lift, will break their lock and cease their firing, and they will be on the move to seek out their foe.
Three different forms of zombies are featured in the Doom games:
* Former human / Zombieman: 20 HP, wears beige armor and has a green crewcut - wields a rifle, will drop an ammo clip when killed. Appears in Doom, Doom II, Doom 64 and Final Doom.
* Former human sergeant / Shotgun guy: 30 HP, wears black armor with bald head - wields a shotgun that he will drop when killed. Appear in Doom, Doom II, Doom 64 and Final Doom.
* Former commando / Heavy Weapon Dude / Chaingunner: 70 HP, dark red armor - wields a chaingun that he will drop when killed. Appears in Doom II, Final Doom and the PlayStation and Sega Saturn versions of Doom.
In the Doom novels, zombies are found in various forms, ranging from former civilians to soldiers. However the former commandos depicted there (referred to as Clyde) are not zombiefied humans, rather they are either genetically engineered human copies or human traitors who have been genetically altered to look alike. They also emit a "sour lemon smell" when killed or nearby.
In Doom 64 there are no real changes in behavioral patterns amongst the zombies; they simply walk and shoot. The only real physical difference is that the Sergeant's pants are a slightly darker shade than the Former Humans (which makes them harder to discern within Doom 64s darkness). The Former Commando does not appear in Doom 64.
In the Doom RPG two classes of zombies exist, each with three variants corresponding to their difficulties. The Zombie classes are named: Zombie Private, Zombie Lieutenant and Zombie Captain. Commando classes are named: Troop, Commando and Assassin.
Imp
The Imp is the basic demonic enemy and common in all of the games because they appear in almost every level, where they appear with a relatively humanoid appearance. In the original games, Imps have brown skin, red eyes, and spikes on their shoulders, elbows and knees. They usually emit a hissing sound when alerted and have 60 HP. They attack at long distance by firing fireballs from their hands, and up close by scratching with sharp claws.
In the Doom novels, imps appear as they do in the older games - however, some can talk, as they are made "leaders" of small groups. Their fireball attack is produced by spitting in their hand, where the mucus then turns into fire. They are referred to as "spinies" and "imps".
In Doom 64, there are the common Imps, which act like their counterparts, though their appearances are slightly different; they have the same physical build and colour, but seem to be devoid of a mouth and several of the protruding spikes. There are also the Nightmare Imps, which have a transparent purple/blue appearance to them, move faster, and fire purple fireballs, though they look essentially the same.
In Doom RPG, three variants of Imp exist. They are Impling, Imp, and Imp Lord. They are weak against shotgun shells. Doom has been criticized for using satanic imagery in its enemies. CNN editor Steven L. Kent stated that the demons' deaths have a "repetitious cartoon quality", in contrast to movies where the characters "often seem to suffer and die slowly". Chris Charla, editor-in-chief of Next Generation Magazine, stated that Doom's use of satanic imagery in enemies (and violence) was copied by many others in attempts to be successful; "people were trying to 'out-Satan' Doom".<ref name="cnn1" />
