So...what is everyone's opinion on Doom Slayer's chances (tbh I never like the name Doomguy and Slayer is more fitting)
Mine's...around 75%.
I know his name is Doom Slayer but calling him Doom Guy is hilarious in a casual sort of way. He's a guy who fights doom. You don't need to know his name, all you need to know is that he is angry.
Onto the "Evidence" that I have for him.
Bethesda talking to Nintendo
Mass advertising of Doom this year
"More surprises for Nintendo fans" - Pete Hines
Hiring "voices" for heavy metal choir in a "video game"
... Oh and I guess the Mii hat if that turns out to be true which it almost certainly looks like it is. Just have to wait for Fighter 5 to see if this is real.
However despite all of that, all of this could fall apart in an instant if he is not Fighter 5 so I'm giving him the same chance as you. 75%
