6. Bouncing Boy

I made the rule to only put ONE Legion of Superheroes character on this list. And I picked Bouncing Boy to fill that slot.

Chuck Taine (Of course, his name is Chuck) was a thirtieth-century earthling, who, like an idiot, drank an experimental potion and gained superpowers. He then, according to this Who's Who entry, loses and regains his powers three times. You know, like a screw up.

In post Zero Hour Legion comics, his full name is revealed to be Charles Foster Taine. That is one of those jokes that, if you get it, will make you seethingly mad at the pun.

This incarnation didn't have bouncing powers and was instead more of a tech support guy for the Legion. Because this version of the character didn't think to do shots of an experimental formula like a moron. Seriously, nice origin, idiot.
