OK, well...

Rawk, Endure for the first round. Then after his health drops, put him down with a combo of Aerial Ace and Vacuum Wave.

If he tries to dodge or block the combo, just Relax until the Poison/Burn (What would that be? Radiation?) does him in. If he tries a move like Taunt to dissuade you from using Endure, smack him with your combo first turn. And if he tries a suicide attack, Protect against it.
