Imp (Doom 2016)

The imp is a large humanoid creature spawned from the depths of Hell who originally appeared in Doom (1993) and has been in every Doom game since. The latest iteration of the imp was revealed in the E3 2015 presentation gameplay footage of the 2016 Doom remake. These imps appears to be taller than in the classic series and are similar in stature and acrobatic skills to imps in Doom 3.

Tactical analysis
Imps can leap in nearly any direction, hang on pillars and walls, and run fast, all while still attacking the player without any pause. Amongst lower-tier enemies they have already been described as "dangerous," with their fireballs doing significant damage, as much as 60 hit points in the game's Nightmare skill level. There is a brief wind-up to their fireball attack, giving barely enough time for the player to dodge if his attention is focused. A "harasser" unit by design, imps will often retreat from the player and try to find purchase on a higher, more distant surface from which to attack. This is in contrast to the previous incarnations of the monster, which always sought to close to melee range - this imp rarely resorts to melee attacks unless the player chooses to close to that range. It will occasionally leap toward the player to strike if it is at medium range, however.

Unique player kills
The imp has a player kill similar to that of the revenant, albeit more gory. It will rip out some of the player's entrails before ripping off his left arm and beating him to death with it.

Design change
Imps underwent a dramatic redesign between the initial public presentation of the game and the release final product. The earlier design was closer in appearance to a smaller version of the Hell knight, suggesting some kind of relationship between the two. The final imp design added distinct features to the head and body, two prominent glowing eyes, and accents of purple color which seem to call back to the nightmare imp.
