The sad thing is, there's a large number of dumb people who actually wanted Waluigi playable.
I can't imagine why or how. He's a completely worthless character, only created because Wario needed a doubles partner in Mario Tennis N64. That was his original purpose, and he served it already. Now he needs to just f*** off.
I always asked Waluigi fans why on earth they would want him taking up roster space, and they always answered the same thing: "DUDE HAVE YOU SEEN HIM IN MARIO STRIKERS?!! HE DOES A CROTCH CHOP!!"
...okay. That's it?
Well, yes. That's the only justification they ever provide: he did a crotch chop. Uh-huh, great.
Save room on the roster for deserving characters, you morons.
