She-Thor?

There's an "s" missing in this phrase: "Whosoever holds this hammer, if he be worthy, shall possess the power of Thor."

Marvel announced on Tuesday that in its new comic book run coming in October, Thor as we know him becomes unworthy of Mjolnir, so the hammer — and the title of "Thor" — will pass on from the son of Odin to ... a woman.

To be clear, series writer Jason Aaron said in a statement: “This is not She-Thor. This is not Lady Thor. This is not Thorita. This is THOR. This is the THOR of the Marvel Universe. But it’s unlike any Thor we’ve ever seen before.”

After dropping the bombshell on Tuesday, announcing that Thor will be a woman in upcoming comics, Marvel has now announced another big change: the next Captain America will be black.

The news broke on the Colbert Report Wednesday: Steve Rogers will have to step down as Captain America this fall, passing on his shield to Sam Wilson, a.k.a the Falcon, an old ally of the Captain.

Tony Stark has always possessed an inner darkness — now he's unleashing it on the world.

Marvel is on a character transformation tear, first announcing a female Thor, followed by the revelation late Wednesday of a black Captain America. Now, as Mashable can exclusively reveal, Tony Stark's massive ego is about to boil over, causing Iron Man to unleash a version of his volatile Extremis technology on the entire population of San Francisco.
