Demon/Doom 3

The Pinky Demon in Doom 3 (a.k.a. Pinky) is very much different from its older versions. It has no visible nose or eyes, its horns point straight forward instead of out from the side of its head, walks on all fours, has a more dog-like reptilian appearance and has cybernetic rear legs. When it is summoned, it makes a screen-shaking effect when it roars.

It attacks in a similar fashion to its classic version by running up to the player and biting them, but due to the player's reduced movement speed, it is much harder to escape from and due to an increased attack speed and range, the attack is much harder to dodge. Additionally, being hit by an enraged Demon disrupts the player's aim, which is very confusing and makes a counterattack nearly impossible.

Like the Doom 3 version of the Imp, the Pinky Demon is tougher than its classic counterpart due to increased firepower in some of the weapons, but it still takes only around two shotgun blasts at point-blank range to kill it.

Tactical analysis
Pinky is powerful and it is normally encountered in small rooms. Although in classic Doom games the chainsaw was extremely useful against the monster as the weapon shielded the player from the Demon's bites, in Doom 3 by contrast, Pinky is able to bite the player anyway; if the Demon gets within range to bite, the player will take damage and lose his aim (if not his arm) from the Demon. Because of this, killing the Demon using a ranged weapon before he has a chance to bite you is essential. Using the pistol, fists and the flashlight on an attacking Demon is not effective. The Chaingun and the Plasma Gun is the most effective weapon against Pinky since the bullets and the cells can take them down in a few seconds. The shotgun is decent enough in a pinch.

Trivia

 * In the Doom movie, the character Pinky turns into a Demon later in the film. This is evident, as the monster inherits his bionic-wheelchair contraption. Why he did not simply mutate into a wheelchair equipped zombie is unknown. One explanation is that because there is technically "less of him" than normal humans, the mutation was more concentrated.
 * The designers have explained the unique face of the pinky demon by describing how it is born: a newborn Pinky's face is buried under thick folds of flesh (that do not, unlike other animals, undergo apoptosis), and the animal must consume itself to breathe and eat.
 * It should be noted in some places in the Hell level of Doom 3, the organic half of this demon can be found hanging on meat hooks. Why they are there is unknown, but they are possibly used as a food source.
