There was a song about James Bond made by the guy "Goldentusk" which made me wish that there was a song made about superheroes - it could be the unknown but funnysounding superhero names. Just a suggestion from one beast to another! Keep on trollin! :)
Ya know, being a cartoonist that also happens to be a huge fan of superheros (and the sometimes goofy nature of their names) I whole heartedly agree with Kendra on this one! A superhero song could be about names... or the most unlikeliest of super heros... lousy powers... you name it!
