RAGE QUIT Something stupid. He'd make use of his powers of persuasion, by which I mean he'd threaten to kill Xemnas if he didn't change Axel back. And then he'd probably go demonstrate that he was serious and it would be time. Odds are Fou-Lu would come along and he'd keep Saix from getting curbstomped, since dragon god > guy who doesn't have a cool nickname. :Db
Pete (yes, THAT Pete) shows up. What does Maleficent do? XD
