I like Batman, despite my marvel roots.
-So much style.
Best team? Juggarnaught, Spidey, Magneto, and Archangel (w/metal wings), Pheonix
-An brute unstoppable force, a master of all magnetic forces and metal (that covers just about everythng), an airborn horseman of the apacolypse (plus he's just cool), the most powerful force in the universe hidden in a very powerful telepath/telekinetic, oh yeah and the most agile webslinging mavel spokesman there is.
Most Underrated? Nightcrawler
-cool powers that never seem to be taken to potential.
Lamest? Cypher
-Okay, so you can read all languages. Ugh. . . right.
Honorable mentions:
Thor, crappy costume cool powers and story.
Shazam/Cap. Marvel, supposedly at least as powerful as Supes.
Taskmaster, I can do anything you can do.
