Suggested by Destroyer Sephiroth still has the most iconic boss theme in video game history. It’s just awesome and Advent Children showed off what he can do in a real fight. He is incredibly fast and his sword gives him a long reach. That being said, Megaman SF is extremely powerful as well. I dare say that he may be faster than Sephiroth and he has a large array of attacks at his disposal. Megaman should have enough tools at his disposal to win this fight. He’ll simply win the match up close and he would also have the edge from afar. Megaman SF wins.
