Valkyrie

Jane Foster lost her mother to cancer when she was nine and was raised by her father. He worked multiple jobs to support her education before dying from a heart attack after she began working as a nurse. Jane served as the assistant of physician Donald Blake without knowing that he was Thor. She developed feelings for both identities until Blake revealed the truth. Thor brought her to Asgard and intended to marry her. Odin granted Jane divine power and immortality before testing whether she could live as an Asgardian. She failed his test and was returned to Earth without her memories of Thor. Jane later married physician Keith Kincaid and had a son named Jimmy. She eventually regained her memories and returned to medicine. Jane completed her medical education and became a doctor who treated ordinary patients and superhuman injuries. Keith and Jimmy later died in a car accident. Jane continued her work and specialized in oncology.

Jane was later diagnosed with breast cancer and began chemotherapy after undergoing surgery. She refused magical treatment because she wanted to face the illness through human medicine. After Thor became unable to lift Mjolnir the hammer called Jane to the Moon and accepted her as its new wielder. She secretly became Thor and defended Earth and the Ten Realms while continuing her cancer treatment. Each transformation removed the chemotherapy drugs from her body and allowed the disease to progress whenever she returned to human form. Jane fought Malekith and Roxxon while serving with the Avengers and resisting Odin’s attempts to reclaim Mjolnir. She eventually revealed her identity after her cancer reached its final stage. Jane transformed once more to confront Mangog and saved Asgard by binding him to Mjolnir before casting both into the Sun. The loss of the hammer returned her to human form and left her near death. Thor and Odin revived her with divine energy. Jane then resumed chemotherapy and entered remission.

During the War of the Realms Jane joined the defense of Earth against Malekith. She took up the damaged hammer once wielded by the War Thor and transformed for the final battle. The weapon broke apart after the conflict and left a fragment attached to her arm. Brunnhilde and the other Valkyries had fallen during the invasion. Their spirits appeared before Jane and entrusted her with their former duty. The surviving fragment became Undrjarn the All-Weapon and allowed Jane to become a new Valkyrie. She continued practicing medicine while guiding worthy souls toward their proper afterlives. Jane carried Heimdall’s spirit across the realms after Bullseye killed him with Dragonfang. She later confronted supernatural threats involving Mephisto and Grim Reaper. During Knull’s invasion she attempted to guide the Sentry and discovered Rūna within a dead Celestial. Jane freed Rūna and began rebuilding the Valkyries while continuing her service across Earth and the Ten Realms.

Appearance: Jane Foster's most prominent feature is the pair of vast, golden-brown wings extending from her back, their feathers layered and detailed, fading from a rich gold near the base to darker bronze toward the tips. She wears a gleaming silver winged helm that frames her face and rises into curved points, with swirling etched patterns across the brow. Her long, dark brown hair cascades down her shoulder in a thick braid that drapes over her chest and reaches her waist, with loose strands. Her armor blends classic Asgardian grandeur with a streamlined warrior’s silhouette. A silver, scale-like breastplate covers her chest and shoulders, catching the light with a metallic sheen. Black form-fitting armor lines her arms and torso, contrasting sharply against the bright silver accents. A pair of ornate golden clasps secure the breastplate at her shoulders, from which a flowing blue cape splits at the legs and trails behind her. Her forearms are protected by bracers, and she wears fingerless gloves that leave her hands free for combat. Her legs are clad in tight, black armor that enhances her agile and powerful appearance, with silver-plated knee guards and wrapped greaves running down to sturdy black boots. The boots are practical yet regal, rising high and flaring slightly at the top.

Personality: Jane is compassionate and strongly committed to preserving life. Her medical training shapes the way she approaches both ordinary patients and supernatural crises. Becoming Valkyrie forces her to accept that some deaths cannot be prevented. She still searches for every possible way to save someone before accepting that their life has ended. Jane can be stubborn when gods or rulers expect obedience without explanation. She judges decisions through their effects on ordinary people rather than through divine rank.

Thor Odinson is Jane’s former romantic partner and one of her closest allies. Their relationship survived separation and Jane’s period as Thor. Thor eventually recognized her as an equal rather than someone who needed his protection. Brunnhilde became Jane’s predecessor and spiritual guide after the destruction of the Valkyrior. Her decision to entrust Jane with the role established Jane as the carrier of their legacy rather than a replacement for Brunnhilde as an individual.

Heimdall became one of the first souls Jane personally guided after accepting her new duty. His death taught her that being Valkyrie required helping the dead rather than always returning them to life. Rūna later became her fellow Valkyrie and partner during threats involving Asgardian souls. Jane also works with Doctor Strange and Night Nurse through their shared commitment to healing. She respects their medical knowledge while contributing her own experience as a physician and supernatural warrior.

Undrjarn transforms Jane into Valkyrie and grants her superhuman physical power. She possesses enhanced strength and durability while empowered. Her endurance allows her to continue fighting after injuries that would incapacitate an ordinary human. Jane can perceive spirits and sense the approach of death through the deathglow surrounding endangered people. She can communicate with souls and guide them through dimensions connected to different afterlives.

Undrjarn is a magical weapon created from the remains of the War Thor’s hammer. It can reshape itself into whatever form Jane requires. She has used it as a sword and as other close combat weapons. It can become protective equipment or create wings that allow her to fly. Jane can also shape it into specialized tools and once used the All-Weapon during emergency surgery on Deathlok. Its changing form allows her to answer both combat and medical emergencies without carrying separate equipment.

Jane is a trained physician with extensive experience in oncology and emergency treatment. She can diagnose unusual illnesses and perform surgery under dangerous conditions. Her former service as Thor gave her years of combat experience against gods and monsters. She combines that experience with Valkyrie instincts and the adaptable forms of Undrjarn. Jane usually fights at close range but can use the weapon’s transformations for mobility and defense.
