"This was not about proving which one was superior," Mewtwo said firmly, "this was a battle to stop that impostor. Granted, to the outside observer, it was obvious that I had gotten quite vicious. However, I know what I can take, and I know how hard I can hit. Thus, when faced with an opponent who was essentially in the exact same strength tier as I am, then I knew that I had to fight it as others would fight me."
He paused for a moment. "Our attacks were evenly matched, our power the same, our strength the same. There were other methods that needed to be employed. I attacked the body, as I knew the weaknesses. I knew where to hit and how hard to hit. To take down a being such as myself requires either a tremendous amount of power or the right shots to the right areas."
