Demonic monster

Demonic monster also known as Demon (mortally challenged), is the designation given to a collection of alien species originated from Hell. And their orginal mission is to conquer the Earth and other dimensions.

Doom
Doom and its retail extension, The Ultimate Doom, include the following monsters:
 * Baron of Hell: Two of these act as the boss in Knee-Deep in the Dead, resembling large pink Minotaurs or Satyrs. It can hurl streaming balls of green flame or energy and employs a powerful clawing attack at close range. They can take enormous punishment before being slain.
 * 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.
 * 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.
 * Demon: 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.
 * Imp: A brown, human-sized humanoid demon that throws round fireballs and claws nearby opponents.
 * Lost Soul: A floating, flaming skull that can rush quickly to gore an opponent.
 * Spectre: Identical to the Demon, except that it is partially invisible.
 * 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.

Doom II
Doom II (and thus also Final Doom) includes the same monsters as Doom in addition to the following monsters:
 * Arachnotron: Strongly resembles the Spiderdemon, but is much smaller, and shoots greenish plasma instead of super-chaingun rounds.
 * Arch-vile: A peach-colored, emaciated humanoid demon who is quite tough for its size. It can summon fire, resurrect dead monsters and is the fastest monster in Doom II (almost one and a half times as fast as the Cyberdemon).
 * Hell Knight: Identical to the Baron of Hell but tanned in color, emits higher-pitched sounds and endures only half as much damage.
 * 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.
 * 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.
 * 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.

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
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). It includes the following unique monsters:


 * Hellhound
 * Kronos

Non-boss enemies in Doom RPG are organized into classes. For example, there are three types of imps, while the 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:


 * Chainsaw Goblins (Lesser Sawcubus, Greater Sawcubus, Chainstrosity)

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.
 * Nightmare spectre

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. The revenant, heavy weapon dude, arch-vile, spiderdemon, Wolfenstein SS, Commander Keen and final boss are not present, but instead it features some new monsters:
 * Mother Demon
 * Nightmare imp

Doom 3
Doom 3 includes its own versions of many monsters from the original games. Some of these, such as the Demon and the Hell Knight, are considerably different from their predecessors.


 * Arch-vile
 * Cacodemon
 * Cyberdemon
 * Demon
 * Hell Knight
 * Imp
 * Lost Soul
 * Mancubus
 * Revenant

Additionally, the following new monsters are encountered:


 * Cherub
 * Guardian of Hell
 * Seeker
 * Maggot
 * Sabaoth
 * Tick
 * Trite
 * Vagary
 * Wraith

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
 * Bruiser
 * Forgotten One (which resembles the classic lost soul more than does its namesake)
 * Hell Hunter
 * Helltime Hunter
 * Berserk Hunter
 * Invulnerability Hunter
 * Maledict
 * Vulgar

 * Cacodemon - Their attacks now blurs the players vision.
 * Cyberdemon - A boss, with several new abilities, including a laser attack and a flame wall.
 * Hell Knight - Resemble their Doom 3 incarnation, but can no longer throw fireballs. Instead they have increased speed and agility to chase and pummel the player.
 * Imp - Far more agile, capable of climbing up walls and leaping over large gaps. Can also charge their fireballs into more powerful versions.
 * Lost Soul - Now explode upon impact.
 * Mancubus - Now covered in armour plating that protects their chests, and can launch their flames in streams rather than just fireballs.

It also includes some new monsters.


 * Cyber-Mancubus - Mancubi with heavier armour, and shoot toxic slime rather than fire, at greater ranges.

 * Hell Razer - Similar to an upgraded Possessed Soldier, Hell Razers are demons with an arm cannon that fires a beam of hell energy.
