what traiphorce said...
and nah

My idea for waluigi won't be anything like Wario. Granted he will have a similar D-Air, but that's about it. I see him as more of a mix of other characters and since I can custom it myself =) He won't be a wario clone, don't worry.
Warios Dair
Peach's Fsmash (tennis racket)
Mario's Ftilt
Diddy's dash attack (waluigi doing a kart wheel seems right to me XD)
stuff like that
then for his specials i'd move to
Give him a stomp for his Down B like Dk's Side B - same as his assist trophy attack, just weaker
I think giving him fireballs for his B attack would be nice, like marios - only he shoots 3 and he can't spam them as quickly....
that's what ive been thinking anyway but we'll see when its capable of it
