Red Sonja

As of June 2019, no plot has been announced. Sonja's backstory in the Marvel Comics is a grim one as it established her as a 17-year-old woman living in the fictional Western Hyrkanian steppes with her father, mother, and two brothers. Sonja is turned into "the She-Devil with the Sword" after a group of mercenaries kill her family, physically assault her, and take all of the family's possessions. A broken young woman, the red goddess Scathach endowed Sonja with the incredible skill to handle any weapons, especially swords, under the special provision she would never be with a man unless he defeated her in fair combat.
