Suggested by Destroyer Chaos is a powerful fighter and while Jet may have the edge in speed, I’m not confident that he would be be able to do much to damage Chaos. Chaos is just too resilient and he has an incredible amount of forms at his disposal. In his Perfect Chaos mode he will really be untouchable here. Your best bet is to just try to run away and get to a safe distance and even that’s not a surefire tactic. Jet will be swept away in the end. Chaos wins.
