Jane Foster

Jane Foster is a fictional character appearing in American comic books published by Marvel Comics, most commonly depicted as a supporting character of the superhero Thor Odinson. Created by writers Stan Lee and Larry Lieber, and artist Jack Kirby, the character first appeared in Journey into Mystery #84 (Sept. 1962). For many years, Foster was a nurse, employed by Dr. Donald Blake, Thor's first mortal host, before becoming a doctor herself. Foster is later revealed to be deemed worthy to wield Thor's hammer Mjolnir when the former is no longer able. During this period, she adopts the mantle of Thor, and joins the Avengers. Foster's stint as Thor ends with the character sacrificing her life and the mantle reverting to the original Thor. After Brunnhilde and the rest of the Valkyrior are killed during "The War of the Realms" storyline, Foster takes up the mantle of Valkyrie.

Jane Foster has also appeared in various media adaptations of Thor. Natalie Portman portrays the character in the Marvel Cinematic Universe films Thor (2011), Thor: The Dark World (2013), and Avengers: Endgame (2019) and will continue in the upcoming film Thor: Love and Thunder (2022), in which she will become the Mighty Thor.
