Enchantress is a villain boss from Marvel: Ultimate Alliance.
Amora was born somewhere in Asgard, her parentage unknown. While still in adolescence, she ran away to the land of the Norns and apprenticed herself to Karnilla, one of the most powerful sorceresses in all the Asgardian dimension. There she studied all the basic arts of Asgardian magic until Karnilla expelled her for being too undisciplined. She picked up further mystical skills from seducing other Asgardian magic and wizards. Centuries ago, Amora enlisted Brunnhilde, leader of Odin's Valkyries, in her plans of conquest. However, Brunnhilde soon became aware of Amora's immoral ends and sought to end their partnership. Amora then used her magic to entrap Brunnhilde within a mystical crystal of souls. Only relatively recently was Brunnhilde freed from Amora's spell. The Enchantress seduced Skurge the Executioner into assisting her in many of her schemes over the years. But while the Executioner was so infatuated with the Enchantress that he would do anything for her, she continually withheld her favors from him to keep him in thrall. In her first encounter with Thor after he gained his human identity of Don Blake, the Enchantress attempted unsuccessfully to seduce Blake, and then ordered the Executioner to dispose of Jane Foster, the mortal woman whom Thor then loved. Thor saved Foster and defeated both the Enchantress and Executioner.
