So that's what it means to be a witch? Killing people to serve your own agenda? No. Not for me. Billy Maximoff to Agatha Harkness

William "Billy" Maximoff is the son of Wanda Maximoff and Vision, and the younger twin brother of Tommy Maximoff. Created and raised within the Westview Anomaly, he, along with his brother, were targeted by S.W.O.R.D. and eventually captured by Agatha Harkness. During the Battle of Westview, the brothers were freed and helped defeat the S.W.O.R.D. agents. Following the battle, Wanda dispelled the Hex; however, Billy's soul jumped into the recently deceased body of William Kaplan. Billy, who became amnesiac, then lived for three years as William Kaplan. However, upon studying witchcraft, he sought to find Tommy and embarked on the Witches' Road alongside Agatha Harkness and her new coven.

You survived like witches have been doing for centuries. You saw an opportunity, an empty vessel, and you moved in. So you broke the rules. Big deal. That's what kept you alive. Agatha Harkness to Billy Maximoff

As Scarlet Witch was terminating the Westview Anomaly, the Kaplan family was driving home. Rebecca Kaplan became distracted by the Hex and drove into a ditch, and her thirteen year old son William took the full force as they smashed into a tree, subsequently hitting his head on the window. As William's heart stopped beating,[2] Billy, whose corporeal form was disappearing due to the Westview Anomaly being dispelled, transferred his soul into the newly deceased body,[16] which had an existing sigil on it, making it so no witch could know his name. He then woke up yelling for Tommy. his parents walked in, he heard what the Kaplans were thinking. He then asked them not to fight, which they said they were not. Rebecca then talked about what the doctor said, stating that the amnesia would just need time to resolve itself on its own, and that he was to be discharged by the next day
