A nameless yet awesome space marine from the 90's videogame DOOM. Impossibly manages to survive against hordes of alien space demon monsters from hell. That are evil. And scary. He also, for some reason knows how to use futuristic and experimental weaponry without training and can pwn demons with just a set of brass knuckles. A chainsaw helps, too.
"Yo, did you see that guy who just mugged that pedestrian? he just went all DOOM guy on him! Check out the brass knuckles!"

also, "the doom guy is badass."
guy 2 : "agreed"
