Suggested by Anonymous Ken is a powerful fighter and he has been shown to be even more skilled than army at times. That being said, he never got the crazy strength feats that Ruu obtained from being a guest star on Asura’s Wrath and other titles. Sonic can run rings around Ken and easily snatch up victory. Ken won’t really be able to defend against Sonic and your attack power doesn’t matter if you can’t land a blow. Sonic wins.
