It is known: the new Thor is a female Thor! As of today, Marvel has released Thor #8, introducing a new "“ sort of "“ player in the Marvel Universe.

The fact they bring out a female Thor is not a surprise: Marvel has confirmed they were about to come up with a female Thor in July, 2014.

But the identity of the newfangled goddess of thunder is a kick in the head: she is none other than Jane Foster.

The shock wave this turn of events created was offset by Jason Aaron with a simple observation: "Jane Foster has been part of the Thor comics and the Thor mythology from almost the very beginning", as quoted by NYTimes.

And he further adds: "The very act of picking up this hammer, of becoming Thor, is killing her. Where we go from here is the real story".

But how will the new female Thor affect the MCU?

The female Thor in the MCU: 3 theories

Indeed, this is the obvious question. Fans have never been too fond of Natalie Portman playing Jane Foster. And Portman herself was never too keen on this role either, as we pointed out here.

We can safely assume there are some bumps here: the fact Marvel has not cast Natalie Portman in any other movies "“ other than Thor and Thor: The Dark World "“ like they did with Gwyneth Paltrow's Pepper Potts in The Avengers is kind of iffy.

1. First theory: Portman back or Foster recast

Now, if the future movies pulling from the Thor lore are inspired by today's issue, they will have to bring Natalie Portman back, right, in order to play the female Thor?

Otherwise they'll have to recast Jane Foster, but I don't think how that does justice to the character. Constancy is a quality I guess all fans can appreciate.
