Back in July, Marvel announced that an unspecified female character will take over as the new Thor in the comic books, which had many fans wondering how this will affect Chris Hemsworth's future in the Marvel Cinematic Universe. The female Thor has already been introduced in the comics, taking over for Thor Odinson after he became unworthy of wielding his mighty hammer Mjolnir, as a result of something Nick Fury said to him. Mjolnir laid idle on the moon until a mysterious woman picked it up, thus making her the new Thor. Wednesday's issue of Marvel's Secret Wars comic reveals the identity of this female God of Thunder, although a few key panels from the comics have leaked, via Team Hellions. Be warned, there will be SPOILERS, so read on at your own risk.

The leaked panels reveal that none other than Jane Foster, played by Natalie Portman in Thor and Thor: The Dark World, is the new Thor, even though it is literally killing her. Jane suffers from a cancer which gets worse every time she picks up Mjolnir, but in the final panel Jane reveals, "I will not stop being the mighty Thor, even though it is killing me." It's also worth noting that the "old" Thor is still around in the comics, dressing in rags and wielding a battleaxe known as a Jarnbjorn.

Chris Hemsworth originally signed a six-movie contract, four of which have already been used up with Thor, Marvel's The Avengers, Thor: The Dark World and Avengers: Age of Ultron. He is coming back for Thor: Ragnarok, which has been rumored to decimate Asgard and set up Avengers: Infinity War Part 1 and Avengers: Infinity War Part 2. There have been rumors that only the new Avengers seen at the end of Avengers: Age of Ultron will be seen in Avengers: Infinity War Part 1, with the original heroes all coming back in Avengers: Infinity War Part 2.

Almost all of the main Avengers' contracts will be up after Avengers: Infinity War Part 2, which has many wondering what Marvel will do in Phase 4. With the introduction of Jane Foster as Thor, it's certainly possible that Natalie Portman could step in, while Anthony Mackie's The Falcon could become the new Captain America, like he does in the comics. Of course, we haven't even started Phase 3 yet, and Phase 4 is a long way off, but the revelation of Jane Foster as the female Thor adds some intriguing possibilities for the future of the MCU. Take a look at the comic book panels from tomorrow's Marvel Secret Wars comic book below.
