The Zombieman (also known as former human and trooper by the DOOM community) is a possessed UAC marine from the DOOM games. During the demon invasion from Hell, these poor souls were reanimated as zombies.
Used as the shock troops of the demonic invasion, the Zombieman's appearance consists of a bloodied, brown standard issue UAC marine uniform, body armor, a rifle, green hair, and reddish eyes.
The zombieman is generally considered the least dangerous enemy in the game; no other monster has a lower movement rate or average damage per attack. When killed, the zombieman falls on its back, blowing bloody chunks through its chest cavity.
