User blog comment:MaleficiousVillain/Wo do you want in SSB but know that they will most likely never put in or really likely but you get the picture/@comment-6604133-20141006000743

This would be a lot more interesting if these were at least mostly Nintendo characters. Like, Herobrine, Batman, and Kratos? I get that's the title, but having characters THIS far-fetched should be obvious they'll never get in.

On this topic though, Waluigi is very likely for a future game.
