7. Nemesis Kid

Wouldn't be one of these lists without a Legion of Super Heroes team member somewhere on it.

I mean, Nemesis Kid was only a Legionnaire for like, an issue, but y'know. And what an issue it was. Adventure Comics #346 was marketed with the promise that four new Legionnaires would be introduced, but one would be a traitor. Who would it be? Would it be Karate Kid? Or Princess Projectra? Or Ferro Lad? Or Nemesis Kid? Not exactly the hardest puzzle in the world to solve. Hmmmmmmm, who's the traitor? Could it be Villain Lad? No, that would be ridiculous. I'm thinkin' there's something up with this metal boy.

Nemesis Kid is able to develop powers that are contradictory to those of whoever he's fighting. If you have ice powers, he'll get fire. If you are a water type, he'll break out that electricity.

If you go scissors, he'll go rock.
