Marvel's 5 next superheroes

The vast majority of comic book heroes are white, which could make the African-American Luke Cage, or Power Man, an appealing alternative for Disney, according to Fishler.

Cage grew up in Harlem and spent most of his youth in the Bloods, a local gang. But when he saw how his gang life impacted his family, he tried to get on the straight and narrow road, only to be thrown into jail just when all seemed to be going in the right direction.

While he was in jail, Cage was handpicked by a research scientist to participate in a cell regeneration project, which, of course, went horribly awry, leaving Cage with superhuman strength. He used his powers to escape from jail and started a 'hero for hire' service in New York's Times Square.
