of pain and anger. The Marine grins upon picking up a new weapon, and the most emotional face is seen when the Marine suffers 20 hit points or more taken away during a single attack, showing a shocked face. The Marine in Doom 64 is less muscular, with slightly modified green armor with black highlights, a black helmet with an antenna, and a blue visor. In Wolfenstein RPG, it is hinted that the Doom 64 Marine is a descendant of William "B.J." Blazkowicz, to whom the Marine's helmetless look in the original games bears a striking similarity. In a reference to the Marine's confrontation with the Cyberdemon, when Blazkowicz defeats the "Harbinger of Doom", the creature states that he will return in the future to confront his descendants.

The Doomguy in the expansion Doom 3: Resurrection of Evil is a different character than the Marine in Doom 3, being older and more heavyset with a buzz cut, and is a Marine combat engineer. Doom (2016) and Doom Eternal Contrary to previous incarnations, Doom (2016)'s Marine is more vaguely characterized: the Doom Slayer is never seen nor heard other than from the first person, and other than gameplay at the beginning of the game that shows him having a white skin color and the muscular masculine suit seen in the introduction, practically no details are revealed. The Doom Slayer's eyes and nose can be made out through the visor of his helmet on the game's box art, the 3D model viewer, and his Quake Champions appearance. It has been also noted for its visibly irreverent tone conveyed by its hand gestures, fist bumping a small Doomguy figurine, and a late-game moment where the Doom Slayer decides to make a
