When it's fully charged, have mario's air item throw down animation, as if calling for his warpstar in midair. I'm not getting your heavy or light thing.
Okay, also the high side smash (the meteor). There's no hitboxes when he pulls it down behind him, it only hits in the start of the move, and the end of the move.
UP smash should be longer. It's to me so far the best move in the moveset, and it needs more knockback also. You can interupt any grab you do, which I think is irritating, since I move right away after a grab only to find that it didn't do anything at all. When you do a charge, Ganon does some animation before going to the right one. Also when you crouch he stands up every once in a while. Sword version needs a new up B. Santiys theif has everything else.
I just noticed than when he does his up-side smash, when he brings the meteor down, his hands go through his body. Still cool animation, it's hardly seen.
