New Move

[Super Buu]

I think you should just keep the original Riposte and remove the 'increases the damage from his punches and kicks' bit. Or you could make it a temporary 'burst' thing where his body is momentarily surrounded by the aura which you can use to break close range melee fights (instead of it lasting the whole fight). Another way to make it more feasible is to have a constant, small drain on his energy to maintain.

The idea itself is pretty clever.
