Doomguy (also referred to as Doomgoy) is a pretty big guy that originated from Earth, but now lives on Mars where he fucks anything that moves. He left Earth in the year 1984 in order to live his dream of being the first guy to beat his dick in space, and on the surface of Mars. After joining the space marines, fucking demons appeared everywhere. He had a fetish for killing, so he made games about his experience to relive the memory and keep his erection alive.
