Doom's protagonist



The Doomguy is a space marine and the protagonist in the Doom games.

Biography
The only thing known about the Doom space marine's life prior to the events of Doom is that he ended up on Mars in the first place because he assaulted a superior officer who ordered fire upon civilians. This background is neither deffinately confirmed nor denied by exposition in Doom 3; all that the player finds out is that they were sent to Mars to essentially "replace on of the guys we lost."

Name
Many arguments have been made over the real name of the Doomguy, or as to whether a name would be appropriate at all. The original story by id Software is composed in second person, suggesting that there is no single "Doomguy" and that whoever is playing the game in effect represents the Doom marine. However, other possibilities for a Doomguy name exist, most notably "Flynn Taggart," the name he was referred to in the Doom novels, and more recently "John Grimm," called "Reaper" by his squadmates, the name he was referred to in the new Doom movie.
