Harvester

The harvester is a multiplayer-only monster from Doom (2016), officially added to the game's demon rune via the Unto the Evil pack.

Appearance
The harvester is a tall demon with an appearance similar to the summoner, but with a body which appears similar to an arthropod exoskeleton made of bone. Other differences include its two distinct horns, a yellow, energy-filled void in the center of its chest, and a single oblong yellow eye on its forehead. It is said to consume souls using its lightning energy.

According to information in The Art of DOOM, the harvester is a minor demon lord and is rarely observed due to its duties in guarding the inner areas of forts and keeps in Hell. It has an insatiable hunger for human souls, which it uses to power its attacks by converting the souls into Hell energy. A stomach sack on the creature's back was meant to hold the souls until they were needed, and would inflate as it filled up.

Tactical analysis
The harvester can drain the life of its enemies using a damaging short-range laser attack and recover that lost energy for itself. A more powerful attack consisting of multiple green plasma orbs can be unleashed by charging. The short range of the laser attack is the monster's greatest weakness.

Pre-release
The harvester was first found by data miners examining the files used by the Doom closed multiplayer alpha test, though it remained unidentified until its official announcement. At that time, the monster possessed dramatic neon green patterns on its arms and chest. In the final game, this occasionally appears as a transitory effect as the demon moves around.
