Doomguy

"At this particular moment in time I don't believe I have a healthier or more deeply felt respect for any object in the universe than this here shotgun..."

- Doomguy

The Doomguy, also known as the Doom marine, is the protagonist of the Doom series of science fiction horror video games created by id Software, and its sequels and spin-off media. In all the games, he is a soldier in the United Nations Space Marine Corps, wearing green combat armor, working with the Union Aerospace Corporation. He never speaks (there is usually no one around to talk to, but he does talk to himself in the comic). It's implied he has a heavy sense of honor, as his posting at Mars was due to his refusal to fire on civilians and subsequent attack of an officer.
