Smash Crusade's implementation of Crash really sold me on him from a moveset standpoint. He has mostly frenetic and short-ranged normals befitting of typical Crash gameplay, but he can also place down boxes (wooden, TNT, or nitro) and shove them around with his Fruit Bazooka for a bit of variety and big-brain trapping potential. It's a bit clunky in execution, admittedly, but it convinced me that Crash could absolutely be awesome in a platform fighter.
