I would like to be put on the support list! Doom Slayer is my most wanted character for the next smash and would be an insta-main for me if he actually got in somehow. I feel like he has next to no shot at making the base roster, but if we can spread the idea around I feel like demand may rise significantly (especially given the convenient timing of the Doom Eternal gameplay showcase and hype) and he could have a decent shot at DLC.
I only see a couple problems with his potential inclusion, being the arsenal of weaponry and popularity in Japan. The super shotgun seems like the most notable weapon issue since it’s the most iconic weapon from the doom series yet has very realistic shotgun properties that may affect rating, among other consequences. I’m not too worried about the chainsaw given that it’s technically a woodcutting tool, the fact that there are already similar moves in Smash (see Bowser Jr’s buzzsaw) and the gore often associated with the chainsaw is not necessary for it to work in Smash, whereas realistic guns seem to be considered intrinsically violent and inappropriate given that you’re pumping hot lead into beloved Nintendo characters. But hey, if swords are allowed, why not cut into your enemies just a little more efficiently? I’m also not so sure how well known doom guy is in Japan or how we’ll received he would be, which I’d think would be a significant factor in character selection. He’s also a wholly western character which is unprecedented. Regardless of how many hurdles he has though, I still really want to rip and tear through the whole Smash roster! ( sorry for the long post lol)
