The past history of Scarlet Witch on Earth-804 mirrors that of her Earth-616 counterpart until the events of the Kree-Skrull War. In this reality, Rick Jones would be slain by Ronan the Accuser. At that time Scarlet Witch, Quicksilver, and Captain Marvel were prisoners of the Skrulls. When Mar-Vell would learn of Rick's death, he would destroy the Omni-Wave Projector he was being forced to build and he, Scarlet Witch and Quicksilver would fight against their captors.
Eventually, Scarlet Witch and Quicksilver would run across Anelle, the daughter of Skrull ruler Dorrek VII who had decided to fight against her father. Scarlet Witch and Quicksilver would join her civil war against her father. In the final battle, one of the Scarlet Witch's Hex Bolts would cause one of Dorrek's blaster to backfire killing him. With Anelle succeeding her father, the Kree-Skrull War would come to an end. In the aftermath, she would be reunited with the Vision whom she would learn had feelings for her.
After the wars end, she would return to Earth and reunite with her fellow Avengers and mourn the loss of their friend and ally Rick Jones.
