Doomguy, AKA Doom Marine by his standard name, is the name given to the player's character in the DOOM game. As the protagonist, the player moves throughout various facilities based on both Mars and Earth and even in Hell, slaughtering the demons as they go.
While the basis for the character is sketchy and the storyline comes in small amounts, this much is clear- all of Hell and demonkind fears Doomguy, as he is described as a sort of prophetic apocalypse for them.
