KO punch is easy to come up with alternates for anyway:
KO Punch - Moves horizontally, high knockback, super armour, meter resets upon death and if you store it too long
KO Uppercut - Moves vertically, everything else is the same
Storage Punch - Moves horizontally, half knockback, no super armour, meter charges quicker and never resets - even if you die.
Easy, the last one is a bit shit, but it's a way of changing the move up a bit more.
