The imps are the first infernal monster found in the relaunch of Doom (2016).
Imps are agile enemies that will use the environment to their advantage by climbing up and down ledges and jumping over gaps. They will often try to stay at a medium distance from the player and throw fireballs at them but if approached they will swipe at the player with their claws then usually try to build a distance from the player again. The fireball can also be charged to deal more damage but will leave the Imp immobile for a short time.
Imps are relatively weak enemies and can be killed easily by almost any weapon. Headshots from the Heavy Assault Rifle can easily dispense them from a distance, and the Plasma Rifle is helpful at close range. Although their fireballs fly faster than in classic Doom, they also take more time to prepare, and an observant player can tell when they're winding up or about to throw and be able to dodge. The challenge, of course, is during a firefight when Imps may be throwing fireballs at the player from behind or otherwise where the player cannot see them coming. On Nightmare difficulty, they can do a large amount of damage.

Despite their low status among the demon ranks and their seemingly endless number, Imps have unique characteristics in battle. Some prefer fighting from an elevated position, while others will rush their target and swipe at them with razor sharp claws. Walls and obstacles offer no defense against Imps as they will leap great heights and easily hang from surfaces. The Imp is capable of channeling Hell energy through its hands and shaping it into a projectile. As the Imp Channels the energy, airborn particles and debris are sucked into the maelstron to create a condensed, superheated fireball. The mechanics of the Imp's ranged attacks suggest that they are actually a lower form of the Summoner.
