4. Hulk - Superpower: Super Steroids
Anger is not a super power in itself - if it was, then every male in their late teens would be causing untold chaos in every city on a daily basis. The only way it can be a superpower is if you inject yourself with a little something-something before you embark on your rampage - yep, it's our old friend steroids again. Granted, Bruce Banner's version of the drug is a little more potent than poor old Captain America's, but you have to remember that Captain America's sweetheart-superhero got jacked-up seventy-odd years ago. But even with the super steroids, it would be a bit of a cheek to call Hulk a "superhero" - the guy himself was born no different from any of us, and is possibly in a far worse position as a result of his transformation. Okay, he turns green, but make any gym-lover on steroids angry and the same kind of "Hulk smash!" thing happens in real life, too. "That's my secret... I'm always angry." Be quiet, Bruce Banner.
