In an explanation posted on its website under the headline, “It’s time for an all-new Captain America,” Marvel announced that the next Captain America will be black. The change comes after the retirement of Captain America’s longtime alter ego, Steve Rogers. He will hand the persona off to his friend Sam Wilson, who is the identity behind Falcon. The update was also revealed Wednesday night on The Colbert Report. The news comes a day after Marvel announced another major change when it revealed that Thor would be reintroduced as a woman. The changes to the characters will be limited to the comic-book pages, and not yet on the big screen.
