Yeah I didn't notice Rocket already had one of the heroes oops. and there is one of the reasons my attempts at Gming don't work. I tend to overlook obvious things like that . Anyway I'll take Vilgax and most if not all of the random enemies hired/used by him to destroy the heroes and take their Omnitrix if that;s okay with everyone
