Storm rules, but I felt her African origin was needless.... Black Panter sucks for the name alone... I liked John Stewart a LOT even if they gave one of his special episodes the lame title of "Blackest Knight".
I like Static Shock. He was a little ghetto, but that didn't seem to force it so they could make sure you knew he was black... it actually seemed just part of the guy who was actually just a young and charismatic character.
Power Rangers runs circles around superhero-dom when it comes to just making a black character a character.
