Except for being slower and dealing more damage, the only difference is that his side-dash thing makes him go diagonally upwards.True, but that still screws you if you want to use a charged-up smash. >.<I don't have those turn around and smash issues because I just use the C-stick.
Also, they should have just kept Mewtwo and left Wolf out. Why do we need three clones of the same character? >_<
And I haven't unlocked wolf yet (only had the game for about a month). Is he really just another Fox clone? :-\
