Let's talk about Silver the Hedgehog. Silver is a white psychokinetic hedgehog from the distant future. He can pick up things and fly in the air by simply just thinking about it.

Just Silver's concept alone makes him sound like an awesome character. Granted, I don't like the game he originally came from, but that shouldn't mean he doesn't make an appearance in more Sonic games (And don't bring up multiplayer. That doesn't count.) He does have a few flaws, though. In 06, Silver's gameplay was super limited, as in his psychokinesis didn't really do much in the gameplay department. Though, in the cutscenes, they make him out to be super overpowered. He can jet off into light speed whenever he wants to, he can hold enemies in place and there's nothing they can do about it, he can create a big psychotic wave to push back anything in his way, and, in a future game, he can even make a giant calamari ball to roll down the highway. So, in the games, he's made out to be either overpowered or underpowered. But, still, I personally think he should make more appearances.

That's just me, though.
