While the list could be infinite with the endless stable of X-characters, my vote would be for the incredible forgotten wonder: RAZORBACK! This guy was the ultimate. His mutant power allowed him to drive or pilot any vehicle. That's IT! Let's see, would that ability allow me to be a superhero? No, I didn't think so. Although I could skillfully steer my car into supervillains who happen to stand paralyzed in the middle of the road. Wait, he also has an incredible "hog's head" that he wears which can give off electrical shocks. How this does not effect him is anyone's guess.
Oh, one more useless character: ROB LIEFELD.

BTW, Firestar and Marvel Boy also double on my list as Avengers. Not reserves either.....how sad.
