Suggested by Sonic Savageman and Copy X are both some of the strongest fighters in their respective sections of the Mega Man series. Copy X has a ton of abilities and is basically X if the hero had ever turned evil. On the other hand Savageman was able to move with tremendous speed before he even had his dark chip infusions. Once he had those then his abilities jumped into a whole new level and I believe he would be able to land enough hits to win before his body would begin to break down. Savageman wins.
