I could go and Google this, but that would be a lot of effort and we need discussion here anyway, so I'll ask haha - what are Capcom characters?
EDIT: OK what the hell. I just Googled it because I have no self-control and I found... well, lets just say I hope that isn't true. Ace Attorney characters? I get annoyed enough just seeing people post Ace Attorney gifs here on PC, let alone having them in my Smash Bros game! And Devil May Cry, Resident Evil and Street Fighter?
Those characters would ruin the game - they are far too removed from the Nintendo characters that make the game what we know and love.
