Jane Foster was originally an ordinary nurse on the earth, employed by Dr. donald black, the incarnation of Thor on the earth, and they later fell in love. However, their love was strongly opposed and repeatedly obstructed by the heavenly father Odin, on the grounds that God and mortals could not be combined. Thor hoped that his father could use Odin's strength to give Jane ability and longevity, but several requests were rejected by Odin. Odin once asked Loki (adopted by Odin as his own child) to send amora, a charming witch who has always had a crush on Thor, to destroy their relationship. After the failure, Odin simply went to the earth and terminated the relationship between Thor and Jane, but this plan was terminated because Loki rebelled and sought the throne. As Thor is always in a love triangle between Dr. donald black and Jane, he reveals the secret of his identity to Jane despite Odin's repeated warnings. Odin was furious and punished Thor, depriving him of half his divine power. It was not until Odin was in danger that Thor tried his best to save Odin and was forgiven, but Thor was seriously injured because he lost half his divine power. Odin felt sorry for Thor. After he was cured, he finally agreed to turn Jane into an immortal god out of love for his son. Excited Thor took Jane to Asgard, where Odin gave her eternal life and divine power. But Jane can't adapt to her super powers, and she can't pass the courage test set by Odin, and she insists on returning to earth. Odin thought that she was unworthy to be the goddess of Asgard, and even more unworthy to be the future queen of Asgard with Raytheon, so she was turned back into a mortal. Her love memory of Raytheon and all relevant memories of Dr. donald black were erased, and she was sent back to earth. Thor is in pain, but he is helpless. After returning to earth, Jane met Keith Kincaid, who is also a doctor of medicine. Being similar to Dr. donald black, Jane fell in love with Keith Kincaid. In order to make Thor forget this love affair with mortals, Odin arranged for Thor to reunite with his childhood playmate Sifu and fell in love with him.

A few years later, Jane died of breast cancer. [2] Saul went to the hospital to visit her and found that his love for Jane had not diminished at all. Seeing that Thor still loves Jane, Sifu injects his life into Jane. Jane recovered her health, her lost memory and her love for Thor, but Sif disappeared. At this time, Jane has merged with Sif's soul, but Sif is trapped in the rune staff dimension. Thor and Jane rekindled their love, but in the process of looking for Sif together, Thor found that Jane had Sif's combat experience, skills and abilities. When Jane holds the sword of Schiff, Jane becomes Schiff, and Jane is trapped in the rune staff dimension. After Thor and Schiff rescued Jane, Jane once again lost her memory of Thor and Dr. donald black, except that she fell in love with Keith Kincaid. Later, Jane married Keith Kincaid, and they had a son, Jimmy. Jane continues to selectively forget the Thor she once loved, and Thor has to let go of Jane.

In the "Ragnarok" incident, all the gods in the fairy palace were destroyed. Thor realized that the essence of the universe had become Thor, the king of runes, breaking the twilight cycle caused by the gods, but he fell into nothingness. At this time, Jane Foster has changed from a nurse to a doctor. Because she is familiar with Superman patients, she became a doctor in The Avengers. Because of her vague memory of Raytheon, she trusted the team, helped heroes such as Iron Man and Captain America in many medical problems, and continued to help the Avengers when necessary.

In the civil war of Marvel Comics, Jane Foster left Iron Man and sided with Captain America, that is, the anti-registration faction. Jane opposes the superhero registration act, joins the Captain America Resistance and becomes a member of the Secret The Avengers. She runs in the No.23 safe house of S.H.I.E.L.E.L.D. As can be seen in the 4th issue of Civil War, Jane helps to treat Spider-Man, and Spider-Man is chased and seriously injured for resisting the registered faction.

A year after the civil war, Thor was awakened in a deep sleep by Dr. donald black. After listening to the stories of Dr. donald black, Thor and the Avengers, and the rumors of the twilight events of the gods, Jane slowly regained her memory. Jane divorced her husband, Keith Kincaid, because he devoted himself to his work instead of his family, but she also lost custody of their children. At this time, Thor, who was born again and had the power of Odin, revived the God of Asgard on earth, but Sifu was gone. Thor turned into Dr. donald black and went to new york Hospital where Jane was located to find Sif. He thought Sif would be reborn in Jane, because Sif's soul has been combined with Jane. Dr. Black was reunited with Jane, but when Jane learned that Donald had come to see Siv instead of staying with her, Jane slapped Donald angrily and ran out. Then Jane realized her impulse and realized that Thor's heart was hard to recover. When Jane discovers that Sif's soul is actually trapped in the body of a dying elderly cancer patient, Jane reminds Dr. Black of her discovery. When the patient was dying, Thor rescued Sifu from death with the hammer of Thor, which only injected Odin's strength and his own soul, and embraced Sifu with joy. Seeing this, Jane finally realized that Sifu was Saul's lover, so she left silently.

Since then, Jane, as a good friend of Dr. donald black, has continued to engage in medical work with Blake. They often exchange information, although Blake is in broackes, Oklahoma, and she is in new york. Jane later moved to broackes, where she worked with Blake to treat patients and help refugees from all over the world.

Years later, Jane's cancer broke out and she was receiving chemotherapy. Her hair has been shaved, and her body is haggard and no longer beautiful. Saul, still young and handsome, came to Jane's house in the evening and talked with Jane for a long time. Jane said she wanted to see the sunrise, so Thor took Jane to the moon to enjoy the magnificent sunrise.

In the latest personal special issue of Raytheon on 20 15, Jane Foster was recognized as the new Raytheon by Mjolnir and participated in the "secret war" on 20 15. 20 16 In the latest comic event "Civil War II", Raytheon played by Jane Foster stood in the Iron Man team and confronted Captain Surprise. When the hammer of Raytheon leaves Jane's hand, Jane will return to the haggard and hobbled cancer patient, and when Jane holds the hammer of Raytheon, she will become a beautiful (female) Raytheon, with great strength and youthful light, wearing a mighty Raytheon shirt.
