Jane Foster was a nurse working for Dr. Donald Blake. Both were romantically interested in each other but neither spoke about their feelings for some time. Blake was forbidden to reveal he was Thor to Foster at the behest of his father Odin which led to tension between the couple. His long unexplained absences caused Jane much distress. Jane was attracted to the dashing and heroic Thor unaware that he and Blake were the same man. Eventually, the tension became too much and Blake revealed he was Thor and he pledged himself to her. Odin however forbid Thor to marry Jane because of her mortality and refused to make her an immortal.
Jane Foster debuted in Journey into Mystery #84 by Jack Kirby, Stan Lee and Larry Lieber. In her first two appearances she was named Jane Nelson, but it was then changed to Jane Foster. She first appeared as the female Thor in a cameo in Thor: God of Thunder issue 25 and fully in Thor Volume 4 issue 1.
Major Story Arcs
Pawn of the Gods
After some time Odin seemed to relent and Thor took Jane to Asgard. Jane became imbued with immortality and became the Goddess of Flight. Odin was angered that she did not take to her new form quickly and set her a task to prove her worth. Despite protests that it was a task only he could perform Odin placed her in a room with the Lurking Unknown. She called Thor for help and Odin deemed her unworthy of godhood. Angered by Odin's tests Jane demanded to be returned to Earth. Odin complied, stripped her of her godhood as well as her memories of Thor and left her in a hospital with Dr Keith Kincaid.
This left Jane incredibly confused as Kincaid was very similar to the forgotten Dr Blake. She and Kincaid began a relationship. After some years Thor discovers Jane dying in hospital, his love for her undiminished. Sif sees that Thor is still in love with Jane and uses her life essence to revive Jane and restore her memories. Thor and Jane renewed their relationship. Unknown to both, Sif's spirit was trapped in the runestaff dimension and Jane could call on Sif's experience and skills to fight. When given Sif's sword Jane and Sif switched places and Jane was trapped in another dimension. Jane was stuck in the Runestaff dimension for some time when the police turned up and arrested Donald Blake on suspicion of her murder. Thor and Sif sought Jane out. After leaving the dimension Jane once again had no memory of her relationship with Thor or Donald Blake. Jane would later marry Keith Kincaid and continued to have selective amnesia for some time.
Resident Doctor to the Avengers
Jane and Keith had a son named Jimmy but their marriage collapsed soon after. Jane left Keith because of his focus on his work rather than his family. In this time she would work with the anti-mutants with her young son in tow. During the Onslaught crisis she volunteered as an experienced nurse to look after the injured.
In this time Jane is able to complete her transition to Doctor and is taken on as the resident Doctor to the Avengers because of her position of trust to the team. She helped the Heroes for Hire, Iron Man and Captain America on many medical issues and continues to provide help to the team when required.
Back in Thor's life
Jane Foster is present on the roof of the hospital she works at when Thor descends from the skies, carrying with him a mortal man in need of medical care. She is delighted to see her old friend, as much time had passed since they had last seen each other and on top of that, there was a lingering question abound concerning whether Thor was actually even alive. Thor likewise is overjoyed to see Jane, and he compliments her in demonstration of this. Jane has time to fill in Thor of the various updates in her personal life. The two depart on friendly terms.
Things however complicate themselves somewhat as Thor is bonded with Earth mortal Jake Olsen, an Ambulance driver working at the same local hospital. Jane is unaware of this as Thor himself was an unwilling factor in this merge. Thor as Jake contemplates telling Jane, but the arrival of Keith Kincaid at the moment he had decided to tell her, seems to sway his mind into confiding in her, wishing to not complicate her life. Jane's reunion with Kincaid after their earlier separation is unexplained. Further more we Jake Olsen's girlfriend Hannah, also works at the same hospital as Jane and Jake, as the two women discuss the problem of missing drugs from the Hospital pharmacy.
In the midst of a medical emergency with Jake at the scene of the emergency and Jane advising from the hospital, Jake disobeys the orders of his superior Jane, based on the knowledge passed on to him, though Thor, from Dr Donald Blake. Jane is somewhat taken aback when Jake mentions his name, and starts to speak in a slight Asgardian dialect. She starts being suspicious of Jake after this incident.
Jane reveals that she knows Thor is present in Jake and urges him to come clean with Jake's fiance. Thor often talks about his fondness for Jane and he is clearly put out by her continued marriage to Keith Kincaid. He comments on how their marriage has been troubled. At one point Keith is put in a coma by a supervillain attack and it is noted how Jane would rather care for Titania than be at her husband's bedside. It is here that Thor and Jane become closer, bringing visible distress to Hannah who sees him as Jake. Kincaid wakes up from his coma and nothing comes from the renewed romantic tension between Thor and Jane.
During the Civil War event, Jane joined the anti-registration side with Captain America, joining his resistance group and operating out of SHIELD safe-house number 23. She and the Night Nurse provided medical assistance to the team.
Return of the Norse Gods
Jane later heard rumors of the return of Dr. Donald Blake and Thor after the incidents of Avengers Disassembled and Ragnarok. Having divorced her husband and lost custody of their child, Blake visited her at her work in a New York City hospital while looking for Sif. Thor was under the impression that Sif had been reborn in Foster since their spirits had been merged once before. The two went on a date after an initially turbulent reunion. But it was Jane who went on to discover that in fact Sif's spirit was residing in the body of a dying elderly cancer patient. Jane alerted Blake of her discovery. He returned as Thor to New York where he was able to restore Sif just before the patient died.
Blake continued his contact with Jane after this. He kept her informed of his life even though he was in Oklahoma and she in New York City. Jane herself later moves to Broxton out of worry for Blake and the two set up a surgery together in the town. She helped Dr Selvong get his message to Thor about the world eaters. She helps refugees from the nine realms find shelter from what appeared to be the end of the world. She appears to have begun some kind of romantic interest in Dr Selvong as she is seen holding his hand during the world eater incident
Jane was later diagnosed with cancer and started a battle against it. Thor was there all the way for her. It was during this time that Thor had lost his worthiness to wield the magic hammer Mjolnir after the events of Original Sin. When Jane Foster was with the Asgardian Gods, she managed to lift the hammer and became an all new female Thor.

This is how she meets Thor who rescues her on a particularly bad outing. Thor is amazed by her heroic nature and develops an attraction to her. Loki, having noticed this, informs Odin about this who gives a disapproving grunt. In a marked difference to the original comics however Odin recognises Jane's bravery which reveals that Odin had been watching Thor all along.
Thor is seen admiring her from afar in 'Breakout' which leads her to ask if he is following her. He is impressed by the fact she doesn't give up on human life despite its fragility. She takes him to a cafe and he talks to her about his problems with his father. She attempts to convince him to return to Asgard for a little while when his family need him. Thor is reluctant to leave mortals and Jane unprotected. They are interrupted by an explosion which Thor uses as an example of why Midgard needs him.
They are seen talking about Thor's problems again in 'Masters of Evil'. She appears to be his confidant and it is here we see Thor's attraction is reciprocated.

In the feature length Thor movie, Jane appears as a main character portrayed by Natalie Portman. Jane Foster is reimagined as an astrophysicist specializing in Einstein-Rosen Bridges connecting the Earth to other dimensions (which are simplified to be labelled as wormholes). In the remote desert town of Puerto Antigua in New Mexico she has assembled a small team of herself, an intern named Darcy and another physicist and friend of her father’s named Erik.
Investigating a strange storm in a late night research trip she and her colleagues drive towards it to record the scientific data but in the confusion accidentally hit an unknown man. After taking him to the hospital Jane discovers on one of the frames of film that she captured the form of a man falling through the storm and she goes to the hospital to question him however he had escaped. Luckily for Jane he had not gotten far and she proceeds to hit him with her truck yet again.
The three researchers are not sure if he is crazy or if the fantastic stories he is telling are true. Jane firmly believes he knows something about the natural phenomena she is investigating and over time is convinced that his tales of Gods and Asgard are true. Soon thereafter her research is seized by S.H.I.E.L.D. agents and she goes with Thor to a secure S.H.I.E.L.D. site where she hopes to retrieve her work and where he aims to retrieve his hammer. He is captured in the process and he is unable to free either the hammer or most of the research, though he does manage to retrieve her notebook of field data.
Despite Erik’s insistence that Thor leave town, the Jane and Thor bond while discussing the idea of the nine realms, as he explains to her and clarifies some of her understanding of the form of travel which Asgardians use. Thor's Asgardian allies and friends eventually come to Earth and they fight the Destroyer. Jane is adamant that if he will stay and help while powerless she will too and they both help evacuate the citizens in the small town. During the battle Thor is returned to full power, at which point he decides he must return to Asgard to confront Loki. Thor promises to return for her and the two share a kiss. In the process of stopping Loki destroying Jotunheim Thor is forced to break the rainbow bridge (Bifrost) which leaves him stranded in Asgard and unable to keep his promise. Jane leaves the desert disappointed but she had not given up. Working with Shield Jane continues her research into the bridge in the hope of making contact with Asgard again. Thor asks Heimdall to look in on her and what she is doing, to which he replies 'She searches for you'. An answer to which Thor smiles.
Although she does not appear in the film herself, Jane Foster is seen on a photo while Phil Coulson tells Thor that SHIELD has placed her in a safe and secure location, after the arrival of Loki.
Natalie Portman reprises her role in the sequel, where Jane has been continuing her research and is now dating a man named Richard. Her relationship with Thor has become somewhat strained, as she is upset that he did not try to contact her when he was on Earth during the events of The Avengers. Thor comes crashing back into Jane's life after her body accidentally absorbs the Aether, a liquid-like substance that is one of the ancient Infinity Stones, while she is investigating the Convergence of the Nine Realms. This brings her to the attention of Malekith, the leader of the Dark Elves who seeks to claim the Aether for himself. After Loki tricks Malekith into extracting the Aether from Jane, she and Thor are reunited on Earth.
Jane is once again absent from the film. It is mentioned near the beginning of the movie that she is busy overseas, as her research regarding the Convergence from The Dark World has resulted in her becoming a highly respected and sought after expert in the field of physics.
