Jane Foster is a respected physician and scientist who became the Mighty Thor after being chosen by Mjolnir. Taking up the enchanted hammer gave her the power of Thor and brought her into a world far removed from her previous life. Since then, Jane has defended Earth as well as the cosmos, proving that she is more than capable of standing alongside the gods and heroes she once only knew from a distance. Despite her extraordinary responsibilities, she has never abandoned her medical career or forgotten what matters to her as a person. Jane is naturally curious and compassionate, though her stubbornness and dry humor occasionally get her into trouble. She has little patience for arrogance and refuses to let others make decisions on her behalf. Becoming Thor changed her life, but it never changed who she was at heart.
