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, the Doom 3 version of Pinky is significantly larger than its classic counterpart, making it tougher if not impossible to dodge around it.

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. The Pinky Demon is a somewhat uncommon enemy. They are usually encountered by themselves, although the player may occasionally encounter 2 or 3 of them in a row. They generally do not attack alongside other enemies, but may appear after the player dispatches a wave of several lesser enemies (i.e. Z-Sec soldiers or Imps).

Tactical analysis
Pinky is large and powerful and 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 couple seconds. The shotgun is decent enough in a pinch, and should take out a Pinky with 2 to 4 shots depending on distance and accuracy.

Although Pinky Demons move slightly faster than the player normally walks, they can be outrun by sprinting. However, they are often encountered while the player is enclosed in small, tight spaces.

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.
 * In the Doom 3 E3 2002 video, in the bathroom, the Marine is hiding behind a corner as a Demon is eating the guts of a Fat Zombie on the floor. This is considered one of the most disturbing and memorable scenes in the demonstration. The Marine then emerges and kills the Demon, taking little harm in the process. Surprisingly, the fat zombie then "awakes" and attacks, forcing the Marine to kill it as well.
 * 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.
