Doom's protagonist



The Doom guy 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 the reason he ended up on Mars in the first place was having assaulted a superior officer for commanding fire upon civilians.

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 claims for a Doomguy name exist, most notably Flynn Taggart, the name he was referred to in the Doom novels.
