The Doomguy, also known as the Doom marine or just the Marine, is the is the main character in the Doom series of science fiction horror video games created by id Software, and its sequels and spin-off media. He is a space marine dressed in green combat armor who never speaks onscreen as well as our hero at the end of Doom II. He has little defined personality, as he is supposed to represent the player themselves. In all the games, this protagonist is a futuristic marine that is never specifically referred to by name. A different way of referring to the protagonist is as the player, although this is a technical designation similar to that of the player character in role-playing games.
Other products that extend the Doom franchise do provide a name for the main character. The Doom novels roughly based on the classic games give the marine the name of Flynn Taggart, and in the Doom movie, the name of the protagonist is John Grimm, nicknamed Reaper. Another game from id Software, Quake III Arena, includes a playable character named Doom that is presented as an incarnation of the so-called Doomguy (as well as a female version named Crash, and another distinct marine character named Phobos). In Doom II RPG the playable marine character is named Stan Blazkowicz, who is a descendent of William "B.J." Blazkowicz of Wolfenstein 3D. John Kane is the marine of the Doom 3 novels.
