Suggested by Destroyer All For One is a pretty powerful fighter and we’ve really seen what he can do against the strongest fighters in his verse. As good as Shishio’s sword skills are, there’s still no way that he would be able to take AFO down. AFO’s barriers would block his strikes and his air bullets are fast enough to tag Shishio and knock him down for the count. Good skills just aren’t enough to make up for the difference in abilities here. All For One wins.
