Well, now we know why Marvel chose to make its announcement today on The View.
According to Whoopi Goldberg and company, for the first time in history, a female character will wield the power of Thor. The story details were light, but apparently Thor will be found unworthy of Mjolnir, leaving a female to take up the power of the Thunder God — and despite her gender, she will still be referred to as Thor.
Goldberg teased that she knew the identity of the character who would take up the hammer before jokingly saying it would be her. Co-host Jenny McCarthy stepped in with a little more background, saying it was a woman who was saved by Thor and then followed him to Earth. After Thor is found unworthy (by Odin, one would imagine), the power and duty that come with Mjolnir pass over to her.
A concept image of the female Thor was shown, and the hosts admired her more realistic proportions compared to many female super heroes.
Expect much more on this breaking news soon.
