Don't really care about Red(unless I'm good with him).
I just really want to use Yoshi, Mario, and Pikachu again. They're my faves.
To me.....
Chances:
----------
Lucario - small chance
Pichu - will definitely be cut! but i can see a new moveset!
......................................................Ok, I can't. WILL BE CUT.
Jigglypuff - she will definitely be back, since she was in ssb.
Mewtwo - a high possibility. there is honestly no reason to cut him off(in my opinion).
Oh yeah, I can see an event match where the player must defeat Red, Pikachu, and some other pokemon.
