Jane Foster

"They stole my life's work, so I don't have much to lose."

- Jane Foster

Jane Foster is an American astrophysicist, who found Thor after he was banished to Earth by Odin.

Fury's Big Week
Jane Foster contacted Erik Selvig to ask if he could help her with her investigations.

Thor
Jane Foster was travelling in a van with her colleague Erik Selvig and her assistant Darcy Lewis, when a mysterious weather event and the subject of Foster's research unexpectedly resulted in a powerful vortex before them. As they struggled to drive through zero-visibility conditions, the van collided with a man who had stumbled out of the dust and into their path. The man, who only announced himself as Thor, was injured again when Darcy tasered him, prompting them to take him to hospital.

The following day, Darcy made a surprise discovery when she noticed the figure of a man in one of the photographic images captured from the atmospheric event. While Jane realized that the newcomer might be able to shed some light on the event, Selvig was more skeptical. So began a lengthy disagreement between the two, with Foster theorizing about the possibility of an Einstein-Rosen Bridge, while Selvig insisted that everything Thor had been saying about gods and other worlds was nothing more than delusional talk based on old myths. Despite Selvig's concerns, Jane's interest in Thor pushed her to find out more, and the trio set off for the hospital to find the stranger. Once they were reunited, the trio and Thor went to a local diner where Jane pressed him for more information, trying to make sense of what he was telling them. It was there that Thor overheard news of his missing hammer, Mjölnir, and set off on his own to retrieve it. Returning home, Jane and her colleagues found S.H.I.E.L.D. agents confiscating their equipment.

After commiserating with her colleagues over the loss of their property (and telling Darcy to stop going on about her lost iPod), Jane chanced upon Thor again and volunteered to assist him with reacquiring his hammer Mjölnir. This goal proved unsuccessful when Thor, after stealing into the temporary S.H.I.E.L.D. compound that had sprung up around the artifact, found himself unable to lift it and allowed himself to be caught.

Jane enlisted Erik’s help in getting Thor released, which led to a series of events that bonded the expanded group more closely, with Selvig befriending Thor while Foster started to view him as a romantic interest. Their time together was cut short when first, several of Thor's friends from Asgard arrived to take him home, and then The Destroyer (a very large battle automaton robot) arrived to stop him from returning to Asgard.

Thor ultimately beat The Destroyer. His willingness to sacrifice himself in the protection of those around him proved his worthiness of Mjölnir, which he regained along with his full power as the God of Thunder. Jane finally saw what he really was for the first time, but with the return of Thor's power came the return of his responsibility to his realm and his people. She was forced to say goodbye as Thor returned to his home.

Thor: The Dark World Prelude #1
Jane continued with her research to find a way to bring Thor back to Earth. She tried to open a wormhole but failed. Darcy tried to convince her to wait, because Thor promised he would return, but Jane worried that he might not, and decided to not give up.

One year later, Thor's brother Loki came to Earth, so S.H.I.E.L.D. contacted Jane and sent her to an Astrophysics Lab in Norway to keep her safe.

The Avengers
Thor asked about Jane's whereabouts when he returned to Earth to bring Loki back to Asgard. Phil Coulson revealed that she, like Erik Selvig, was now working for S.H.I.E.L.D. and that she had been placed in a secret location (Tromsø, Norway) to protect her after Loki took Selvig.

Thor: The Dark World Prelude #2
In Tromsø Jane became frustrated due to no-one giving her a reason for her being there. She confronted one of the scientists when Darcy interrupted her to show her live footage of Thor in Manhattan.

Jane and Darcy flew to New York where Jane promised Erik Selvig that she'd look after him, before realising that Thor had already returned to Asgard.

Thor: The Dark World
"We're from different worlds, maybe they were separate for a reason."

- Jane Foster
