These two characters are certainly iconic DBZ villains. Their overwhelming power was stunning and the heroes really had a tough time against them. Of course this match is a no brainer if you’re just looking at the main material, but these two have gotten many power ups over the years in spinoffs and video games. Still, Cell hasn’t quite gotten a form that lets him surpass Buu yet. Buu has done a good job of keeping pace with just about everyone. Even now there aren’t too many villains who are actually stronger than him. Buu wins.
