Thundra is a fictional character appearing in American comic books published by Marvel Comics. She is often aligned with the Fantastic Four. She is a powerful, red haired, amazon-like warrior, or Femizon, from a matriarchal, technologically advanced future timeline where men have been subjugated by women. Publication history Thundra was created by Roy Thomas and John Buscema, and first appeared in Fantastic Four #129. Roy Thomas recalled the character's creation, "A 7-foot Amazon type that I conceived as an homage of sorts to characters like Kirby's Big Barda in his Fourth World by DC Comics. I asked John Buscema to give her a bandolier around her torso because a number of women's-lib types were wearing them (sometimes with real bullets) in photos in newspapers and magazines." Fictional character biography Thundra is a warrior woman and time traveler from an alternate future 23rd century. In the future society she hails from, planet Earth is now known as Femizonia and is ruled by amazon-like female overlords (Femizons) who have conquered and enslaved the diminished male population. The former United States is now the 'United Sisterhood Republic', and Thundra hails from the megalopolis of Greater Milago (a merged sprawl of Milwaukee and Chicago), located in the United Sisterhood's Midwestern Republic. Thundra is renowned as the United Sisterhood's most formidable warrior, having been physically enhanced by genetic engineering and trained from childhood in combat, the martial arts, and military strategy.

By beating the Thing in combat, she feels she can prove once and for all that women were superior to the male gender, and finally end a stagnant war between Femizonia and the warlike, male dominated planet of Machus, where the female population had been subjugated by its ruler Mahkizmo. Thundra is also recruited into the evil group of supervillains known as the Frightful Four by the Wizard, and they battled the Fantastic Four. She secretly has her own agenda and has no real interest in the group. She battled the Thing in personal combat, and then wound up ultimately switching sides and helping the Fantastic Four defeat the Frightful Four after she quits that group. She later battled the Hulk, who was possessing the Thing's body at the time. Thundra later assisted the
