Doctor Jane Foster is one of the world's leading astrophysicists, the world's foremost astronomer, the creator of the Foster Theory, as well as one of the premiere experts on Asgard. She found Thor after he was banished from Asgard and fell to Earth while she and her team were in New Mexico studying astronomical anomalies. She helped him in his mission to return to Asgard, eventually falling in love with him along the way. They were separated due to the temporary destruction of the Rainbow Bridge. During Loki's assault on Earth, S.H.I.E.L.D. kept her out of harms way by transferring her to a remote observatory where Loki could not find her.
She found out of Thor's return through the footage of the Battle of New York; this left Foster disappointed and angry that Thor didn't attempt contacting her. During the Convergence, she became host to the Aether and helped Thor defeat Malekith during the Battle of Greenwich. Once free of the Aether, Foster returned to work and Thor had decided to remain on Earth with her. Due to her work studying of the Convergence, Foster was being considered for the Noble Prize in astrophysics. Following the Ultron Offensive, Foster ended her relationship with Thor.
Five years after the Snap, the Avengers discovered a way to reverse the effects of the event by traveling back to certain moments in time to obtain the Infinity Stones. Thor and Rocket Raccoon returned to an alternate reality version of Asgard in 2013 during the Second Dark Elf Conflict to obtain the Reality Stone. While that version of Foster was resting, Rocket extracted the Aether from her body.
Jane Foster was a student at Culver University, where her father and Erik Selvig worked together. She later graduated and became an astronomer, dedicating her life to her research, where she built most of her equipment herself. Foster also briefly dated M.D. Donald Blake, but eventually broke up with him. When looking back at him, Foster would note that while Blake was a great doctor, he sucked at being a boyfriend.
Sometime after her graduation from Culver University, Foster began studying a mysterious weather event that she believed was linked to an Einstein-Rosen Bridge. Accompanied by Selvig and their intern Darcy Lewis, Foster traveled to the source of the anomalies, which was out in the desert surrounding Puente Antiguo, New Mexico.
- "Where did he come from?"
- ―Jane Foster
At the end of their first week of research, Foster became certain that another weather event would occur, due to the predictability of the previous seventeen instances. Being sure of her research, Foster, Erik Selvig and Darcy Lewis drove out to the desert in their van one night to witness the event.
When nothing happened, Selvig attempted to convince Foster to give up her search, believing it to be just chasing storms, not connected to astronomy. However, Foster was determined that there was a connection in her research, pleading Selvig to just be patient with it. Suddenly, Lewis alerted the two to something unknown forming in the sky, much to their confusion and amazement.
With her research proven to have been correct, Foster told Lewis to drive towards the occurrence so she could study and record it. As they got closer, a powerful vortex formed in front of them, so Lewis steered away from it, only for Foster to force them towards it. However, when they entered the vortex, they struggled to see anything, causing them to collide with a man who had stumbled out of the dust into their path.
The occurrence then ended, with the vortex disappearing, so they all got out of the van to check on the man they hit. Foster found the man to still be alive, as he got up and began to speak, although none of them understood what he was saying. Foster then noticed markings in the ground, much to her intrigue, so she started to study them, however Selvig suggested they take the man to the hospital instead. The man announced himself as Thor and started to intimidate them, but was stopped when Lewis tasered him. They then decided to put Thor in their van and take him to a hospital.
They delivered Thor to the hospital and signed him in, giving them his name, and then returned to their research base. The next morning, they discussed the events of the previous night, which Foster was now certain was an Einstein-Rosen Bridge. Foster and Selvig reviewed constellations they had discovered which were not from their planet, when Lewis noticed the figure of a man in one of the photographic images captured from the atmospheric event.
Foster then believed that figure to have been Thor, so she decided to drive back to the hospital to question him. The three rushed through the hospital, but when they entered Thor's room, they discovered him to be gone. Annoyed that she lost he best piece of evidence for her research, Foster set out to find Thor. However, when she reversed the van, she accidentally hit Thor again. Foster got out of the van and apologized, as she had now knocked him over twice with her van.
- "If you take me there now, I'll tell you everything you wish to know."
- ―Thor and Jane Foster
Bringing Thor to the base, they provided him with Donald Blake's clothes, and Foster started to become distracted by Thor as she watched him change. When Thor mentioned that he required food, they took him to Isabel's Diner, where Foster questioned him on how he was inside the vortex. However, Thor didn't take notice of their questions and smashed a mug in request of another drink, causing Foster to tell him not to do that anymore.
When two men entered the diner talking about a "satellite" that landed in the desert, Foster listened in on the conversation, and asked them about it. When they revealed that the "satellite" could not be moved, Thor asked for directions and then headed off, causing Foster to run after him. Foster asked what he was doing, and Thor informed them that the "satellite" belonged to him and he was going to take it.
Thor then offered to tell Foster everything she wanted to know about him if she helped him retrieve Mjølnir. Concerned, Erik Selvig spoke to Foster, who was willing to help Thor to assist her own research, and convinced her not to, as he believed Thor was dangerous. Foster then told Thor she couldn't help him, so he kissed her hand, which awkwardly flattered her, and they parted ways. Although, Foster couldn't help but still be infatuated with Thor.
When they returned to the base, they discovered S.H.I.E.L.D. agents confiscating their equipment and research. Foster was angry at the agents sudden intrusion into their base, but Erik Selvig tried to calm her down, due to knowing how serious the actual situation was.
However, due to her life's work being taken from her, Foster tried to stop them, but Phil Coulson told her they needed to take all of her possessions, and attempted to compensate her. Despite her pleas, all of Foster's belongings, including her research that was on the verge of an extraordinary discovery, were taken.
S.H.I.E.L.D. then left the base, so they then sat on the roof of the building, commiserating the loss of their property, as Selvig informed them of who the people that they encountered were. Selvig then suggested contacting a colleague of his who could possibly help with their situation.
Search for Mjølnir
Foster drove up to him and offered him a lift, deciding to help him, as she wanted to get her research back. The two then drove down to the crater site, determined to retrieve their possessions, which Foster was nervous about doing. During the drive, Foster bonded with Thor, while still not being sure of who he was.
When the arrived at the S.H.I.E.L.D. Crater Investigation Site, Foster observed the area, realizing that there was no satellite crash, but something bigger. Thor then gave Foster his jacket, knowing it was going to rain, and promised to return her belongings after retrieving Mjølnir. However, Foster doubted Thor's chances of success, but he still heading to the site.
Foster then watched as Thor made his way through the site, knocking out many agents along the way. When an alarm went off, Foster hid from detection and called Selvig, telling him she went with Thor and to come find her if she didn't return. When Thor found Mjølnir, Foster watched as he tried to lift it but failed. When Thor was arrested by S.H.I.E.L.D., Foster then fled the site and returned to the base, but, she was spotted by Clint Barton.
When Foster returned, she tried to convince Selvig to help free Thor, now believing his story, but Selvig didn't want to, still trying to protect her from him. When Darcy Lewis showed Foster a book on Norse mythology, featuring Mjølnir, she used what Selvig told her about uncovering every possibility to persuade him, but Selvig didn't mean Magic, but science. However, Foster reasoned that magic was just science they didn't understand, and she was able to enlist Selvig's help.
Bonding with Thor
While Erik Selvig went to retrieve Thor, Foster returned to her camper, where she read more of the book Selvig had found. Later that night, Thor arrived at the camper with a drunk Selvig over his shoulder, so Foster had him put Selvig on her bed. Feeling embarrassed by her living situation in front of Thor, as she never has guests, she asked if they could go outside.
The two then sat on the roof of her base, where Foster would always go to think or get away from all the annoyances. Foster then expressed her relief that Thor was safe after his encounter with S.H.I.E.L.D., and he thanked her for her generosity despite the way he had behaved recently. Thor then gave Foster her notebook, which she was delighted by, no longer having to start her research from scratch now. However, Foster was saddened by the thought that S.H.I.E.L.D. would do everything in their power to stop her research from ever being published, but Thor urged her to continue, knowing that she was right.
Thor explained to Foster that where he is from, Asgard, Magic and science are the same thing, while also drawing and teaching her of the Nine Realms and Yggdrasil, the World Tree. Foster found herself deeply interested in what Thor was saying, as well as developing strong feelings for him too. Later, Foster fell asleep under the stars with Thor by her side.
Thor, who believed he was banished from Asgard, decided to embrace living on Earth with Foster, as the two had begun to develop romantic feelings for each other. The next morning, Foster and Thor made breakfast for Selvig and Darcy Lewis, who she told what she had learned from Thor the previous night, hoping to publish it to the scientific community. But, Selvig informed her that it was only ever going to be a theory without any evidence.
At that moment, four Asgardians appeared at the base, much to the Humans shock and awe. They entered the base and introduced themselves as Lady Sif and the Warriors Three, and Foster watched as Thor conversed with them about his supposed exile, only to discover that his father was still alive, and that he had been lied to by his brother.
When another vortex formed out in the desert, they all went outside to look at it, where Thor realized that the Destroyer had been sent down, causing him to warn Foster to leave. Thor told them that he would stay to help the people get to safety, so Foster decided to stay as well, not wanting to leave Thor, as well as help out.
After evacuating everyone in the area, Foster watched as Sif and the Warriors Three battled the Destroyer. When the Destroyer quickly overpowered the Asgardians, Thor ordered to them run away before they were caught in the destruction. As they went to leave, Foster noticed Thor staying behind to confront the Destroyer, so she stopped, confused on what he was doing.
Foster watched as Thor attempted to apologisze to his brother, but it did not work, and the Destroyer strikes Thor, sending him flying back. Foster quickly ran to Thor's side to check on him, and he told her that she was now safe as he died from his injury, to the sadness of Foster. As Foster wept over Thor's body, Mjølnir began to launch from the desert and fly towards them, so Erik Selvig grabbed her and got her to safety.
When Mjølnir arrived, it helped revive Thor, who caught the hammer, allowing him to regain his full powers and reveal his true self, much to Foster's amazement as she witnessed everything he had told her to be true. Foster continued to watch as Thor battled the Destroyer in the sky, ultimately defeating it, saving them from the danger that Loki had unleashed.
Thor then returned to his friends, with Foster commenting on his new armor he was wearing, which she liked. Thor then announced that he needed to confront Loki, but were stopped when S.H.I.E.L.D. arrived. Thor confronted Phil Coulson, telling him to return the items he took from Foster, which he complied with, wanting her to continue her research.
Thor then invited Foster to accompany him to see the Bifrost Bridge, which she accepted, so he held her tight and flew them out to the desert. When they arrived at the Bifrost site, Thor discovered Heimdall not responding. After some delay, the Bifrost then opened and Thor told Foster that he needed to return to Asgard to stop Loki, but he would return for her after. Foster then passionately kissed Thor goodbye, accepting his promise.
Thor and the other Asgardians then departed from Earth and Foster stayed at the site with Erik Selvig and Darcy Lewis to wait for him. While they waited, they noticed where the Bifrost opened to begin producing dark lighting clouds, much to their concern. After some time, they then saw the Bifrost opening completely disappear before them, saddening Foster as she felt that Thor had abandoned her. They then decided to leave, accepting that Thor was not returning.
Away from Thor
Working with S.H.I.E.L.D.
- "Of course you can have your equipment back. You're gonna need it to continue your research."
- ―Phil Coulson to Jane Foster
After Thor's departure, Foster entered a partnership with S.H.I.E.L.D., providing them the information Thor shared with her regarding the Nine Realms, making her something of an expert adviser regarding Asgardian cosmology. With S.H.I.E.L.D.'s resources, Foster worked extensively in her attempts to create an artificial wormhole with hopes of reuniting with Thor in Asgard. She nearly succeeded after months of work, but yet again, Foster eventually failed. Darcy Lewis tried to convince her to wait, citing that Thor had promised her he would return for her, but Foster was worried he would not.
In 2012, Thor's brother Loki made an alliance with the Chitauri and declared war on humanity. When Erik Selvig was mind controlled by Loki, Foster and Darcy Lewis were immediately moved to an observatory in Tromsø by S.H.I.E.L.D. for their own protection. During this time, Thor was transported back to Earth to stop his brother; Foster had no immediate knowledge of his return.
While in Tromsø, Foster was left in the dark regarding her sudden and immediate transfer, and became frustrated when she was not given an explanation. During an attempt to confront one of the scientists, Darcy Lewis showed her live footage of Thor in Manhattan fighting the Chitauri in the Battle of New York.
Foster and Lewis flew to New York City and reunited with Erik Selvig, who was visibly shaken after being brainwashed by Loki. Foster asked Selvig about Thor's whereabouts and was downtrodden to learn that he had already returned to Asgard. Despite comfort from Lewis, Foster was upset that while she had spent a year trying to create a wormhole in order to reunite with him, Thor had found a way to return to Earth and yet chose not to reunite with her or even leave her a message, prompting her to resign from S.H.I.E.L.D. and move on with her life.
Moving to London
A year later, Foster received a call from Erik Selvig, who, after spending several months enduring psychiatric care, had traveled to London without her knowledge. Selvig explained to Foster that he had discovered a series of bizarre anomalies in London, and needed her to come to London and meet with him. Foster traveled to London, accompanied by Darcy Lewis, but Selvig was nowhere to be found.
Foster moved into her mother's house, which she and Lewis operated out of to conduct their research, which Foster had personally given up on. Despite deciding to move on from Thor, Foster found herself struggling to move on from him, spending most of her days in her mother's house, moping around in her pyjamas, hardly showering.
Some time later, Foster would be asked out on a date by Richard Madison, which she accepted to try and help get over Thor. However, when they went to a restaurant, Foster spent most of the date hiding behind her menu, still finding it hard to move on.
Madison then initiated a conversation, asking Foster what her story was, suspecting it had something to do with another man. Foster alluded to Thor, informing Madison that he was away. Madison then informed Foster of a previous relationship, where his girlfriend cheated on him while in New York.
Suddenly, Darcy Lewis showed up and interrupted their date, informing Foster that the Phase Meter started acting up. When Foster looked at it, including banging it on the table, she brushed it off as nothing, but Lewis believed it to be the readings Erik Selvig mentioned to them. However, Foster told Lewis to go away, so she did, allowing Foster to return to her date. As the date continued, Foster couldn't help but be distracted by what she had seen, so Madison to let Foster leave the date to go with her friend.
Possessed by the Aether
Foster then joined Darcy Lewis in her car, as she knew she would come, much to Foster's annoyance. As they drove to the location, Foster was shocked when she discovered Ian Boothby in the backseat, who was Lewis' intern. Foster then tried to contact Erik Selvig to tell him about their discovery, but was once again was unsuccessful in reaching him. When they arrived, Foster explored the area until Lewis called her and they went towards the warehouse.
When they entered the warehouse, they discovered three kids inside, who asked if they were the police. Foster revealed to them that she was a scientist and asked if she could see what they had found, so they brought them to a truck that was levitating in the air, which one of the kids was able to flip over with ease, to Foster's awe.
The kids then showed them up a stairwell, where one of the kids dropped a bottle down that suddenly vanished on the way down. When Foster asked where it went, the bottle reappeared from higher up. Excited by this anomaly, Foster threw a can, but it did not return, which one of the kids revealed sometimes things don't return. Foster started to analyze the anomaly, noting how the readings were similar to when Thor arrived in New Mexico.
Leaving the others to play with the portal, Foster went to investigate the anomaly, detecting more readings as she explored the warehouse. When Foster came across a dark hallway, the Phase Meter started to emit stronger and wilder readings as a powerful gust of wind emerged. Suddenly, Foster was mysteriously pulled forward and swallowed through a portal.
Foster was transported to an alien world, much to her shock, where she attempted to call out for help, but there was no response. Foster then explored her surroundings, where she discovered the Chamber, possessing an unknown red substance inside it. When Foster looked inside, the substance latched itself onto her, slithered out and was absorbed into her.
After entering through her hand and now completely surging through her body, Foster became terrified, not knowing what was happening to her. In shock, Foster then passed out, allowing the substance to take control over her and started to grow stronger. Fiver hours later, Foster was transported back to the warehouse, where she awoke, unsure of what just happened to her.
Reunited with Thor
Foster then exited the warehouse, where she discovered the police had arrived and were talking to Darcy Lewis, who had called them. Foster was mad at her for ruining their unimpeded access to the anomaly, which she now feared that S.H.I.E.L.D. would arrive and take over, but Lewis revealed that she had been gone for five hours.
When it started to rain, Foster noticed none of it was occurring around them, to their confusion. However, the cause for strange rain occurrence was revealed when Foster spotted Thor, who had returned to Earth, standing before them. Foster then walked over to Thor, with the rain still not going on her, and slapped him to check if he was real, due to experiencing several strange occurrences that day.
Now certain that it is him, Foster slapped Thor again for leaving her and never coming back even though he promised her he would. When Foster asked where Thor was, he asked the same question back, informing her that Heimdall could not see her. However, Foster ignored it, telling Thor about how she was distraught after he left. Thor then explained to her that he was unable to return for her, as the Bifrost Bridge was destroyed and he needed to protect the Nine Realms from the chaos that ensued.
Foster then brought up that she saw Thor on TV when he was in New York with the Avengers, but he once again explained that it was to protect Earth form the dangers of his world. Thor then expressed that he was wrong for allowing his duty to not return to Foster, and that he believed it was fate that had brought them together once again. Finally reunited with each other, Thor attempted to express his love for Foster, as they moved in to kiss.
They were interrupted when Lewis walked over to them to inform Foster that they were about to be arrested. Foster then left her moment with Thor to deal with the police, who questioned whether she knew Ian Boothby, who they were frisking. An officer then told Foster that she was trespassing on private property, and when he went to grab her, the substance fused in her reacted, releasing a powerful blast of energy, knocking the officer away.
This blast caused Foster to fall to the ground, and Thor rushed to check on her, protecting her from the police, who wanted to take her in. Knowing that there was something wrong with her that was beyond human containment, Thor decided to call upon the Bifrost to take her to Asgard. Foster held onto Thor as they travelled from Earth in the Bifrost, being amazed by what she was experiencing, and long dreamed of doing.
Learning of the Aether
Worried about her condition, Thor brought Foster to a group of Asgardian physicians to be examined. While Foster was in the Soul Forge, she couldn't resist the urge to ask questions about it. After an inspection, she realized that the Soul Forge was just like a quantum field generator, spurring the physicians with her level of knowledge.
Suddenly, Odin entered the room, where he expressed that Foster does not belong on Asgard, being a mortal, despite Thor telling him she was sick. Insulted by Odin's words against her, Foster spoke up, only to be informed that he was King of Asgard, Thor's father, and that he knew who Foster was.
Thor tried to convince Odin that Foster was ill, only for the King to remind him that her world had doctors, which could treat her. Odin then ordered guards to escort Foster out of Asgard, but when they touched her, the Aether reacted again to protect her, knocking away the guards. Odin then understood the severity of Foster's illness and examined her, determining that the Aether was protecting itself, not Foster.
Odin then showed Foster and Thor the Book of Yggdrasil and explained the history of the Aether, an Infinity Stone that takes the form of a liquid, unlike the other stones. Odin also explained how it has the power to change matter and that it seeks out host bodies, where it draws its strength. Foster then asked Odin if he knew how to get the Aether out of her, but he didn't know.
- "Listen to me now. I need you to do everything I ask, no questions."
- ―Frigga and Jane Foster
Not able to remove the Aether from her body, Thor decided to keep Foster in Asgard for her own safety. Foster was escorted to her chambers, where a maiden provided her some clothes, although she attempted to request something with pants, to the maiden's confusion.
After Foster rested, she went to explore Asgard, where she became captivated by the Magnetic-Propulsion Ball, believing it could advance Earth science significantly. Foster was then joined by Thor, who informed Foster that she had accidnelyy taken a ball from some kids, so she returned it. The two took a walk around the Asgardian Palace. During their walk, Foster asked Thor how he knew to find her when she was in trouble. Thor explained to Foster how Heimdall could not see her on Earth when she discovered the Aether.
Thor then taught Foster about the Convergence, an event where the Nine Realms align perfectly, which was how Foster was transported from Earth to the Aether's location. Listening to Thor explain things to her, Foster found herself immediately falling back in love with him, and the two shared a kiss.
Scared on what would happen to her, Thor promised Foster he would find a way to save her. The two were then joined by Frigga, who Thor informed Foster was his mother, which made her nervous as she greeted the Queen. Soon after, they noticed a commotion from the Asgardian Dungeons, so Frigga told Thor to investigate it, promising to look after Foster.
Foster then stayed with Frigga as she went to find Odin, expressing her concern for his safety. As the two had an intimate conversation, Foster noticed Sif walk by, and the two stared at each other, although for different reasons. Frigga then armed herself and asked Foster to do everything she asked with no questions, which she complied with. Frigga then brought Foster to her chambers and created an illusion of her.
Foster then hid as Malekith entered the chambers, where he was confronted by Frigga. Malekith then revealed he came for the Aether inside Foster, so Frigga attacked the Dark Elf to protect Foster. After a brief duel, Frigga overwhelmed Malekith, but was stopped when Kurse entered, who restrained her. Malekith then approached Foster, only to discover the illusion Frigga had cast, causing him to order Kurse to kill the Queen. When Thor arrived, Malekith retreated, and Foster came out of hiding, finding Frigga dead.
That night, a funeral was held for those who were killed in the skirmish, including the Queen of Asgard, who died protecting Foster from the Dark Elves. Foster attended the ceremony to pay her respects to Frigga. During the funeral, Foster stood with Thor to support him as they watched Frigga's spirit ascend to Valhalla.
The next day, while Foster was sitting in her chambers, the Aether gave her a vision of Asgard consumed by the its darkness. When she snapped out of it, Foster decided to visit Yggdrasil in the Hall of Science so she could work, as it helped her when she didn't know what to do.
Foster was able to understand how to operate it very quickly, where she learned more about the Aether. When Thor entered, Foster apologized, blaming herself for Frigga's death, but Thor told her it wasn't her fault. Foster then informed Thor of her discoveries, when they were interrupted by Tyr, who came to imprison Foster under Odin's orders. Thor refused to let her be imprisoned, but Foster agreed to be taken, not wanting to cause anymore problems.
- "I'm not hungry."
"Good. Let's go."
- ―Jane Foster and Sif
Imprisoned in her chambers, Foster was brought a meal, which she refused, just as Sif arrived and knocked out the two guards. Sif told Foster to come with her, as she was freeing her as apart of Thor's plan to defeat Malekith. Foster was reunited with Thor, as well as his brother Loki, who she recognised from his attack on New York, so she punched him.
When the Einherjar arrived to stop them, Thor escaped with Foster and Loki to leave Asgard, while Sif stayed behind to give them time. They came across Volstagg, who was waiting for them by a Harrow ship for them to escape in. Once they boarded the ship, Thor, after several failed attempts, managed to fly them out of the Asgardian Palace. While escaping, Foster became faint due to the Aether draining her, causing her to collapse.
When they reached the Rainbow Bridge, Thor picked up Foster and exited the ship, landing in an Asgardian Skiff piloted by Fandral. Thor then laid Foster down so she could rest, as Loki took control of the skiff to take them a secret portal. Loki was successful in helping Foster and Thor escape Asgard and arrive in Svartalfheim.
Having successfully arrived in Svartalfheim, Loki piloted them through the wastelands from First Dark Elf Conflict as Foster continued to rest on the Asgardian Skiff as she was getting weaker from the Aether.
Soon after, Foster was awoken by the Aether, allowing her to alert Thor and Loki that they were approaching Malekith's location. They then exited the skiff and continued on foot, where they reach the top of a cliff, spotting the Dark Elves exiting an Ark. Thor then checked if Foster was ready, preparing to execute his plan to have the Aether removed from her body, which she confirmed she was.
When Thor uncuffed Loki, Foster watched as the God of Mischief betrayed his brother, stating him with one of his daggers, unknown to Foster that it was apart of the plan. Foster then chased after Thor, who was kicked down the cliff and had his hand cut off by Loki. When Foster went to check on Thor, she was grabbed by Loki, who used her to bargain with Malekith to watch Asgard fall.
Malekith then commenced removing the Aether from Foster, raising her up and draining it from her body. As the Aether was being removed, Foster saw another vision of Malekith's plan to cover the entire universe in darkness. The Aether was then completely separated from Foster, so Loki cut the illusion, allowing Thor to summon Mjølnir to destroy the Aether. Thor sent a blast of lightning into the Aether, Loki dived to protect Foster from the explosion.
However, they were unsuccessful, as the Aether soon reformed and was absorbed by Malekith. The Dark Elves, having got what they wanted, began to leave, with Kurse throwing a Black Hole Grenade at them, causing Loki to push Foster out of the way to save her. Foster got to safety as the two bothers faced off against Kurse and the Dark Elves, allowing Malekith to escape.
The fight came to an end when Loki used a Black Hole Grenade to kill Kurse, also resulting in him being fatally stabbed. Foster then came out of hiding and watched as Loki died in Thor's arms, sharing a look of sadness with Thor as Loki had helped save her life. When a storm came over Svartalfheim, the two found refuge in a cave, where Foster informed Thor of Malekith's plan to go to Earth.
Return to Earth
- "The walls between worlds will be almost non-existent. Physics is going to go ballistics. Increases and decreases in gravity, spatial extrusions. The very fabric of reality is going to be torn apart."
- ―Jane Foster
When Foster revealed that she only found the Aether because she was looking for Thor, she suddenly received a phone call from Richard Madison. Foster answered the call, amazed by the incredible reception she was receiving.
Foster then explored the cave for answers only to realize that they were near the portal she discovered in the stairwell back in London. Foster picked up the car keys that Ian Boothby threw into the portal, and she and Thor walked through it, being transported to Earth. Foster and Thor, having returned to London, found Darcy Lewis' car and used it to return to her apartment, while Thor questioned Foster on Madison, to her annoyance.
When they entered Foster's apartment, they found Lewis and Boothby inside, who were surprised by their sudden return, not knowing where they had been since they left Earth. Foster then discovered Erik Selvig was there, too, and they hugged, as she asked for everything he had on the Convergence. Foster then went to get changed out of her Asgardian dress, and the group formulated a plan to stop Malekith.
Foster used the vision she saw to inform the rest of Malekith's plan to fire the Aether where the Nine Realms will connect, increasing its power, causing mass destruction. Selvig was able to figure out Malekith's location to unleash this chaos in Greenwich. Foster then stated the importance of stopping Malekith, as the fabric of reality would be torn apart if he is successful.
The group then travelled to Greenwich where Foster, Erik Selvig, Darcy Lewis and Ian Boothby went around the site planting the Gravimetric Spikes to disrupt the Convergence. Foster teamed up with Selvig as they entered the library, where Foster was shushed because her boots were making noises.
When Foster and Selvig planted their spike, an Ark arrived as the Convergence begun, so they rushed to the top of the tower. As Thor battled Malekith on the ground, Foster was attempting to activate the spikes, which Selvig was not sure would work. However, they were still waiting for Lewis and Boothby to finish as Thor continued to buy them time.
Foster then went to check on Lewis and Boothby, who had planted their last spike, giving Foster the signal to activate them. With the Convergence fully aligning soon, Foster then began to keep Malekith and the Dark Elves busy, using the spikes to teleport the Dark Elves through rifts. While using the spikes, Foster accidentally teleported Lewis and Boothby away with two Dark Elves.
Having completed their task, Foster and Selvig then left the tower, warning the people in the library to also get to safety. As the two exited the building, the connection to the spikes was lost, as they were chased by a group of Dark Elves. As they ran away from the Dark Elves, Foster reactivated the spikes, allowing her to teleport them away, while simultaneously teleporting Lewis and Boothby to their location, discovering them making out.
With the Convergence aligning and Malekith unleashing the Aether's power, Foster noted that they were out of time and went to retrieve the spikes. When she regrouped with Thor, they informed him that the spikes could still stop Malekith, but they needed to get close, which Thor could do. Thor then took the spikes and headed towards Malekith in the Aether storm, as Foster watched on, standing by to activate them.
As Thor hurled two spikes at Malekith, Foster activated them, teleporting his arms to Svartalfheim. When Thor impaled the last spike into Malekith's chest, Foster activated it, teleporting the Dark Elf away from Earth. With the threat eliminated, Foster checked on Thor, who had been knocked out. Noticing the Ark collapsing, Foster then ran to Thor to try and save him, but he was too heavy, and she couldn't move him.
With the ship about to crash on top of them, Foster accepted that she couldn't save Thor and decided to hold onto him, not wanting to be without him. While waiting for the ship to crush them, Foster discovered that Selvig had been teleported it away, saving them. Now that the battle was completely over and the Convergence ended, Foster rested herself on Thor as he woke up.
Relationship with Thor
Thor told Foster that he had to return to Asgard to resolve everything with his father, as he committed treason when they escaped. Two days later, Foster and her friends were having breakfast in her apartment, still waiting for Thor to return, although the others were doubtful if he would anytime soon.
However, much like last time, Foster still remained hopeful that he would return as promised, especially after how their relationship had developed previously. As Foster sat at the table, she heard the roar of thunder followed by the Bifrost Bridge appearing outside. When Foster turned around, she became excited to see that Thor had returned, and rushed outside. The two then passionately embraced each other and proceeded to live out a life with each other.
Due to Thor's celebrity-like status as an Avenger, Foster's relationship with him then became publicly known. Foster kept studying the effects of the Convergence in London, making important discoveries in the field of astrophysics, and becoming a serious candidate for winning a Nobel Prize for her work. When Foster was showing her work to Thor at the University of London, they were interrupted by J.A.R.V.I.S. to inform them that Thor was needed to help fight HYDRA. Foster later lectured about her experiences on interspace and dimensional travel at WHiH World News.
Breaking Up With Thor
- "Sorry to hear that Jane dumped you."
"She didn't dump me, I dumped her. It was a mutual dumping."
- ―Fan and Thor
Some time after the Ultron Offensive, Foster broke up with Thor. Shortly after, Thor left Earth in order to locate the remaining Infinity Stones, although he briefly returned to New York City two years later, where he tried to explain to a fan, as well as Loki, that the breakup was a mutual decision.
Death and Resurrection
In 2018, Foster was among those many individuals who perished when Thanos, who had completed the Infinity Gauntlet with all the Infinity Stones, caused the Snap to wipe out half the life in the universe. However, Foster was eventually resurrected along her fellow victims when Hulk snapped his fingers in 2023.
- "Do you have any pants?"
"Never mind. These will be fine."
- ―Jane Foster and an Asgardian Maiden
In an alternate 2013, Foster enquired a maiden if they had any extra pants before retreating into one of the chambers and taking a rest. When she awoke, Rocket Raccoon infiltrated Foster's chambers, snuck up behind her and used a device to extract the Aether from her body, prompting him to be chased by the Einherjar. After the Battle of Earth, Steve Rogers returned the Reality Stone to Asgard, albeit in its solidified form.
Jane Foster is an extremely intelligent scientist, having built most of her equipment herself. She is also spirited and impulsive; she argued with the S.H.I.E.L.D. agents who confiscated her equipment, and slapped Loki immediately upon seeing him.
Powers and Abilities
- Master Scientist: Foster has become one of the most important astrophysicists in the world, having studied the existence of Einstein-Rosen Bridges, also known as wormholes, since before discovering their true nature through her experiences with Thor. Once he departed from New Mexico, Foster developed a revolutionary theory on wormholes known as the Foster Theory. She began to give lectures around the world, and she was even considered a serious candidate for the Nobel Prize.
- Phase Meter: Foster used this device to measure the cosmic energy anomalies within the Nine Realms. This device was used when Foster came across a series of portals created due to the Convergence.
- Reality Stone: A strange red liquid, which was actually one of the Infinity Stones, that absorbed itself into Foster's body, using her as a host to draw from and grow stronger. While fused with Foster, the Reality Stone would release a violent blast from her body to protect itself. It was finally extracted from her body by Malekith, as well as Rocket Raccoon in an alternate timeline.
- Magnetic-Propulsion Ball: An Asgardian toy that Foster believed could be a scientific breakthrough for Earth.
- Gravimetric Spike: A device designed by Erik Selvig to stabilize the focal point of the Convergence and pass by its effects. Foster planted these devices to teleport the Dark Elves away, stalling their plans.
- Dark Elf Harrow: Following Malekith's attack on Asgard, Foster joined Thor and Loki as they commandeered an abandoned Harrow left by the Dark Elves. As they escaped in the ship, Foster fainted and was carried off the ship to the Asgardian Skiff.
- Asgardian Skiff: After departing from the Dark Elf Harrow, Foster boarded the ship with Thor and Loki as they escaped from Asgard to Svartalfheim and travelled to confront Malekith.
- Culver University: Foster attended Culver University as a student and would eventually graduate.
- Jane Foster's Research Base: When Foster moved to New Mexico to look into anomalies out in the desert surrounding Puente Antiguo with Erik Selvig and Darcy Lewis, they operated out of a lab to conduct their research. When they met Thor, they allowed him to stay at the base with them. The base was completely emptied out when S.H.I.E.L.D. arrived to confiscate their equipment, but later returned it so Foster could work from the base for S.H.I.E.L.D..
- Jane Foster's Apartment: Originally her mother's place, Foster moved in to the apartment after she was called London by Erik Selvig. Foster used the apartment as her lab, although she found herself spending all her time moping around, still hung up about Thor. When Foster returned to Earth, she went back to her apartment where her team formulated a plan to stop Malekith. After the Convergence, Foster witnessed Thor arrive at her apartment to live a life with her on Earth.
- Asgardian Palace: When Thor discovered something to be wrong with Foster, he brought her to Asgard to help her. After learning the that the Aether was inside her, Foster was allowed to stay on Asgard for safety, given her own chambers, which she was imprisoned in temporarily after the Sacking of Asgard.
- University of London: When living in London, Foster found employment at the University of London, where she would continue her research in astrophysics, the Nine Realms and the Convergence. Thor visited Foster at the University, where she brought him to the observatory, telling him about her research.
|Appearances for Jane Foster|
|In chronological order:
- In the comics, Jane Foster eventually took up the mantle of Thor after he lost his ability to wield Mjølnir and was stripped of his powers.
- Natalie Portman desired the role of Foster because the character is an astrophysicist in the films despite being a registered nurse and medical doctor in the comics.
Behind the Scenes
- Chris Hemsworth hosted an episode of Saturday Night Live on 7 March 2015 in which he portrayed Thor in an Avengers-themed skit. During the skit, Thor refers to Jane Foster as his "ex", leading some to speculate that they had broken up between the events of Thor: The Dark World and Avengers: Age of Ultron. Chris Hemsworth later clarified that Thor and Jane were still together during that time in an interview.
- Dorenda Moore and Elsa Pataky were stunt doubles for Natalie Portman in the role of Jane Foster.
- Faye Sewell was a stand-in for Natalie Portman in the role of Jane Foster.
- According to Natalie Portman, the reason for which Jane Foster wasn't written into the story of Thor: Ragnarok was because of its setting: Obviously, I wasn't written into Thor: Ragnarok because of where it took place. It wasn't really on Earth, and my character is on Earth.
- Natalie Portman did not shoot any new footage for Avengers: Endgame, only recording a new line that Jane Foster speaks when heard speaking from a distance, and all of the footage of her is recycled from Thor: The Dark World. The film's first draft had Jane talking with future Thor upon meeting him during the Time Heist, but Frigga ultimately filled that role. A scene featuring a conversation between Jane and Rocket Raccoon in which the latter tries to explain her what he is going to do before taking the Reality Stone from her was cut.
- A.C. Bradley originally pitched an episode of What If...? featuring Jane Foster's transformation into Mighty Thor, but her idea was nixed because Taika Waititi was keeping it for Thor: Love and Thunder.
