Origin

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.

Creation

Jane Foster debuted in Journey into Mystery issue 84 (1962) by Jack Kirby, Stan Lee and Larry Lieber. In her first two appearances her name was Jane Nelson, with her surname later changed to Foster. She first made a cameo appearance as the Mighty Thor in Thor: God of Thunder issue 25, and made her first full appearance in Thor Vol. 4 issue 1 (2014). Her first appearance as Valkyrie was in War of the Realms Omega.

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.

Civil War

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

Becoming The Mighty Thor

Jane was later diagnosed with cancer and started a battle against it. Thor was there all the way for her, especially during her chemo-therapy. 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 found the hammer and actually managed to lift it, becoming an all new female Thor. She kept her newfound powers a secret to everybody, and has since been trying to learn how to use her new awesome powers. The only downside to her powers is that when she transforms into Thor, all the chemo is driven out of her body, since it is basically poison. This however did cause Jane to keep getting sicker and sicker. As Thor, she felt no effects of the cancer. During a skirmish against a rogue Chitauri named Warbringer, Jane joined the All-New, All-Different Avengers.

Recovery

While Jane continues to receive treatment at the McCarthy Medical Institute, she assists Agent Solomon and the All-Mother Freyja in relocating refugees from across the realms to the Bronx, New York. Despite no longer possessing the power of Thor, she proves herself useful by feeding Thor Odinson intel on hotspots through Midgard that require attention and being Roz Solomon's "women in the chair." After numerous treatments of chemotherapy and radiotherapy at the McCarthy Medical Institute, Jane is told that there are no more signs of cancer in her liver or lymph nodes. She is in remission, and can finally rejoin the fight against Malekith on the eve of his invasion of Earth.

War of The Realms

When Malekith the Accursed leads his army into New York as part of the Midgard Invasion, Jane assists civilians in evacuating into the Sanctum Santorum. She senses that the heroes are in peril and commandeers an Asgardian ship to fly into battle, helping Freyja and Robbie Reyes before Odin and his Valkyrior arrive to bolster Midgard's forces. Jane manages to distract Malekith's War Witches long enough for Doctor Strange to cast a powerful evacuation spell, which accidentally teleports all of Earth's heroes to Avengers Mountain. Some Asgardians make it to the portal in time, but the Valkyrior are left behind and are slaughtered.

King In Black

When the symbiote god Knull descends upon Earth, the hero Sentry attempts to halt the invasion single-handedly. Knull tears Sentry in half, and Jane fulfils her duty of care by escorting him into the realm between realms.

Rejoining The Avengers

While on shift at the McCarthy Medical Institute, Jane is brought the body of a Deathlok who was found outside Avengers Mansion. The Deathlok has been sent by Avenger Prime to warn the Earth-616 Avengers of the "infinity requiem." Jane takes the Deathlok to Avengers Mountain to seek their aid, but the Mountain is sieged by the Multiversal Masters of Evil. Black Panther asks for Valkyrie's aid in the assault alongside Namor, and Jane & Mr. Horse escort Deathlok to recalibrate the Celestial's defense systems, but they are intercepted by Doom the Necromancer. She fights Doom one-on-one, whose death magic is countered by Jane's power as a Valkyrie, but Doom outmanoeuvres her until Black Panther returns to the fight with blessed armor. The two battle Doom until the Celestial headquarters explodes with the team inside, and Namor and T'Challa keep the rubble from collapsing while Jane performs emergency surgery on the severely injured Deathlok. The rest of the Avengers arrive but the Masters of Evil have already retreated, and Jane is able to treat the wounded accordingly. When the dust settles, Jane was asked to join The Avengers once more.

By joining the team, Jane is instantly targeted by Mephisto as a key player to corrupt in the coming war. She awakes within a bubble reality with no memory of her former life, happily married in domestic bliss with Thor Odinson. Though her new life is idyllic, Jane's old life begins to bleed into her thoughts, and painting pictures of an armored angel with golden wings. Trapped in the Silver Age cycle of being Thor's love interest and damsel in his adventures, Jane feels a nagging pull that she is meant for something more. She knows that Mjolnir used to talk to her, but "Thor's" is silent. In lifting it she proves it is a forgery, and the glamour is broken on her idyllic prison. As the facade melts around Jane, her jailers are revealed to be three Multiversal Mephistos from the Council of Red, whose task was to corrupt Jane but now wish to kill her. Their efforts are blocked by a Mighty Thor from another reality, and the two Jane Fosters battle the Mephistos until they retreat. Variant Jane gives 616 Jane a warning about the multiversal war and guides her home, where she alerts her fellow Avengers to the importance of the God Quarry at the end of space and time.

Multiversal War

Jane joins the Avengers in their journey through time, back towards the genesis point of Earth's defenders of 1,000,000 B.C. She confides in Thor her worries about meddling with the timestream, and the two have a terse back-and-forth regarding Jane's possible temptations following Mephisto's attempted recruitment of her. While travelling through time proves more difficult with Mephisto's interventions, Jane notices the team's youngest recruit, Brandy Selby, is burning herself out with the power of the Starbrand. Jane uses her own experience with death to comfort Brandy, telling her that life, no matter how fleeting, is the most precious thing in this or any other reality. She tells Brandy to cherish what little time she has, because they will beat Mephisto by outliving him. Brandy hears her words, and uses huge amounts of the Starbrand's power to finally transport the Avengers to 1,000,000 B.C.

There, Valkyrie and the Avengers meet the prehistoric mantle holders of Earth's most powerful forces. There is a brief clash between the two teams - including a rematch between Jane and Odin - before Necromancer Doom arrives with his Multiversal Masters of Evil. The prehistoric & modern Avengers join forces to battle the Masters and appear evenly matched, until Doom unleashes a plague mist that begins to spread across the lands in an effort to end humanity before it begins. Valkyrie flies into action along the prehistoric Ghost Rider to save as many neanderthals as she can but, seeing how futile it is unless a choice is made, the Rider sacrifices himself by burning his Spirit bright enough to scorch the mystical plague. When the surviving 616 Avengers and prehistoric powers recover, they are summoned by Avenger Prime (revealed to be Loki) to fight in the battle of the God Quarry against an army of Doctor Dooms.

During the chaotic multiversal war, Mephisto is able to manifest enough dark power to breach the God Quarry, revealing it to be a dam holding back the liquified remains of the First Firmament. This flood of living entropy crashes into the battlefield, threatening to wash away all living matter in the cosmos from the God Quarry outward. The Phoenix Force - possessing a Logan from the end of time - attempts to hold back the tidal wave of cosmic entropy, but the strain is too much on his physical body. Jane uses Undrjarn to perform triage on him, holding together his body as it breaks down in front of her. She also assists the Goddesses of Thunder by calling every Mjolnir in the multiversal battleground to hold back the flood, until Robbie Reyes closes the breach from the other side, saving the cosmos. In the aftermath, Brandy Selby uses the last of her Starbrand lifeforce alongside the Phoenix of 1,000,000 B.C. to send Jane and every Avenger back to their restored universes. Jane stands with her fellows Avengers in mourning for Brandy and Robbie and, after searching for their souls in the afterlife, she takes a leave of absence from the team.

Vs. Cosmic Ghost Rider

Journeying through the cosmos, Jane discovers a massacre onboard a fueling station at the hands of the Cosmic Ghost Rider. Jane mistakes this alternate future form of Frank Castle as her Earth's counterpart, and warns that the Rider's actions shall lead to his own demise. After battling and failing to apprehend one Cosmic Ghost Rider, a second one appears and Valkyrie uses her Death Vision to guide the two halves of Frank's self toward one-another. The Rider's nightmares reveal a magnetic field had warped time-space and separated Castle into his two selves, and Jane offers duty of care to the two, assisting in his journey to becoming whole once more.

Avengers Inc.

As part of her duties as a Valkyrie, Jane goes to Janet Van Dyne and Victor Shade to help solve the murder of Skurge the Executioner within the halls of Valhalla. Jane notes how peculiar Victor looks when seen through her death-vision, but nonetheless brings the two to the sacred hall. After Jane and Brunnhilde stop a particularly rowdy brawl among the Einherjar, Victor Shade is assaulted by the Grim Reaper who is still residing in Valhalla after Jane gave him a "warrior's death" to end his rampage on Midgard. Jane grants Victor part of Undrjarn to defend himself while the Wasp interviews Asgard's fallen warriors and determines that it was in fact Odin who was responsible for Skurge's death. The former All-Father, in his Harbardr form, had requested Skurge leave Valhalla by sacred death to aid his son Thor on Midgard and prevent an ominous prophecy. The nightmare in heaven states that the current wielder of Mjolnir shall die. Jane protests that Odin should have alerted the Valkyrior - or at the very least herself - but Odin cautions that any warning on their part may bring about the very prophecy they seek to avoid.

Later, when Wasp required support in defeating the new Lethal Legion - revealed to be infected by Ultron's code after being separated from Hank Pym's body - Valkyrie was called upon alongside other Honorary Avengers to the battle.

The Immortal Thor

When the primordial Elder God Toranos - First of all Thunderers - comes for the All-Father and Asgard, Thor calls upon his friends who have wielded the power of Mjolnir and the power of thunder to his aid. Valkyrie takes up the power of Thor once again and, alongside her fellow Thunderers Beta Ray Bill, Storm and Loki, the Thor Corps are reborn! With sixty seconds before the transformation is reversed, each member of the Thor Corps aids the All-Father against Toranos by passing Mjolnir between them amongst blows, until the Elder God catches the hammer in his own hand. This is by Thor's command as the All-Father, who grants Toranos the powers of Thor, among which are the gifts of restraint, compassion and humility. This empathy for life causes Toranos great distress, who flees from this plain of existence, leaving the Thor Corps with questions, but ultimately victorious.

After the day is won, Jane attempts to warn Thor what she learned with Wasp, Brunnhilde and Victor Shade in Valhalla. Though Odin advised the Valkyrie not to alert his son, Jane sees the orb of Death looming over Thor's head and concludes it is part of her Hippocratic Oath to forewarn him so he may prepare for this dark fate.

Powers & Abilities

As Thor, Jane wields Mjolnir, and like those before her, she has been bestowed with power equal to that once possessed by the Odinson by the hammer; whatever powers she may or may not possess outside of those provided by Mjolnir are unknown.

Superhuman Strength: In her Asgardian form, Jane possesses class 100 strength and is easily capable lifting/carrying massive weight far exceeding 100K tons.

Superhuman Speed: Jane can also think, react and fight at superhuman speeds while in her Thor form.

Superhuman Durability/Stamina: While in the form of an Asgardian Goddess, Thor possesses virtual invulnerability and immunity to all known Earthly diseases and infections. She can exert herself at full intensity for hours at a time before beginning to fatigue. She is also capable of surviving in the vacuum of space unaided.

Healing Factor: Like all Asgardians, Thor has a highly advanced metabolism that enables her to recover with superhuman speed and efficiency. While the extent of ability to heal is unknown, it doesn't appear to be able to heal her cancer. Instead, the cancer appears to be suppressed and isn't lethal to Thor as long as Thor retains her Asgardian form.

Death-Vision: As Valkyrie, Jane possesses the ability to "see" how near or far a mortal is from Death's embrace. This vision manifests as dark cloudy orbs floating above the individual's head, which the person being closer to their death the larger their orb looms.

Afterlife Teleportation: Like all the Valkyrior, Jane can transport herself and others across the threshold of the living plain into the afterlife. Usually Jane transports the souls of the departed to the Halls of Valhalla, however she has been shown to take them to different heavenly plains.

Equipment

Mjolnir

Mjolnir the former weapon of Thor, is a hammer forged from Uru metal, whose chief properties are durability, the ability to maintain enchantment, and absorb energies. Mjolnir resembles more of a short handle mallet than a traditional warhammer. Mjolnir itself is already extremely durable, and combined with the various enchantments placed upon it by Odin, is even more durable. It has survived heat as extreme as the heart of the Sun, and can absorb and redirect energy blasts powerful enough to destroy planets.

Worthiness Enchantment: This enchantment surrounding Mjolnir prevents it from being wielded by anyone save those who have been found worthy. Thus far, this includes Thor, Thunderstrike, the Red Norvell, Beta Ray Bill, and Captain America, and now Jane Foster . To anyone else, Mjolnir cannot be lifted from the ground nor wrested from Thor's grip. Those who are deemed worthy are able to wield Thor's powers Recently the enchantment has changed to the point that Odin; its creator can no longer carry it (or presumably bypass the enchantment), whether Beta Ray Bill and others are still considered worthy is unknown.

Transformation: Jane Foster can use Mjolnir to transform into her Thor persona.

Mystical Link: Can sense the presence and whereabouts of the hammer when separated from it

Flight: Like her predecessor, Jane is capable of hurling Mjolnir with great force and, by holding onto the leather thong, is capable of flying through the air at tremendous speeds. While in an Earth-like atmosphere, she generally flies at roughly the Speed of Sound, ( 770mph). The hammer can also be directed from a distance; this aspect was used offensively against the frost giants during her first appearance.

Weather Control: Jane relies on Mjölnir to control weather with devastating degree. She can summon storms, rain and lightning from the sky. She can also create weather manifestations not typical to the climate/geography in which she finds herself.

Energy Projection/Teleportation: With Mjolnir, Jane can project powerful mystical blasts of energy, as well as instantaneously transport herself (and others) over vast distances.

Allspeak: Thanks to the Allspeak, Jane can communicate and be understood by all races.

Undrjarn The All-Weapon

Made from the mystically-melted remnants of Earth 1610's Mjolnir, Undrjarn the All-Weapon is a powerful liquid gold substance that manifests as whatever weapon or enhancement that Jane requires at that moment. In its dorment state it takes the form of a golden vambrace on Jane's right forearm, and its favoured weapon form is that of a mace.

Weapon Manifestation: Undrjarn can take the form of any weapon that Jane requires.

Flight: Undrjarn can take the form of a large pair of golden wings that Jane uses to fly at great heights and speed.

Healing/Regeneration: Jane has used Underjarn's purity in tandem with her medical expertise to assist in healing wounds, creating enchanted medical equipment such as oxygen masks, and crafting armor for weakened individuals.

Film

Thor (2011)

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.
