The Doomguy (also spelt Doom Guy, as well as referred to as the Doom Marine, Doom Slayer or just the Slayer in Doom (2016) and Doom Eternal) is a fictional character and the protagonist of the Doom video game franchise of first-person shooters created by id Software.

The sole non-playable character, Buddy Dacote, bore the most similarities to the original game's eventual protagonist.
