It’s a battle of psychics in this match! If we were going by pure psychic abilities then Mewtwo would have the clear edge, but overall fighting ability makes this closer. Silver has his Super Silver form and while it’s never looked as impressive as Super Sonic/Shadow; it’s still a force to be reckoned with. Mewtwo has his own super form, which greatly increases his speed. After a solid fight, I’d give this to Mewtwo. His healing abilities matched with his immense speed and long range abilities give him the slight edge. Naturally, Silver just needs a few good scenes in a new anime or video game to help even the odds. Mewtwo wins.
