Prototype is actually pretty good.

Some reviews comment that the game-play becomes repetitious but I just finished up a level in which I had to protect a tank traveling through infect territory. There I am, with my special 'Infection Vision' turned on and my 'whip arm' slicing and dicing the bad guys as I ride on top of the tank. Pretty fun.

And ya, I'd agree... visually, he's the most powerful video game character ever.
