Suggested by Sonic Sebastien is a demon so he has supernatural abilities at his disposal. His speed and power are both far greater than that of the average man. Dr Satan is a villain who has a lot of tools at his disposal but he is still no stronger than a human. Sebastien can easily speedblitz this guy with no true effort and one punch should do the trick. These two are in different leagues and it’s hard to take down a demon without some special equipment. Sebastien Michelis wins.
