Scarlet Witch
Billy has said that Wanda Maximoff, the Scarlet Witch, was his favorite Avenger, and it has been implied that his powers are linked to hers. Billy joins Tommy as they search for the Scarlet Witch through Genosha and Wundagore before finally encountering Master Pandemonium at a former residence of the Scarlet Witch and the Vision. Master Pandemonium decides not to fight the boys after recognizing Wiccan's magic as being the same as the Scarlet Witch's. Instead, he elaborates on their history concerning Mephisto and the Scarlet Witch and advises them that the history they search for is filled with "darkness and chaos" and that they should embrace who they are in the present.
