Suggested by Sonic Chaos has quite a few super forms at his disposal. With each Chaos Emerald he consumes the guy gets a massive power boost. In his Perfect Form he can even take out an entire city. That won’t mean much to a duelist like Crow though. Crow has a ton of cards up his sleeve and most of them are quite powerful. Birds of a feather flock together and that’s how Crow assembles a lot of monsters at one time. The sheer numbers will easily take Chaos down. Crow wins.
