Jullian Hillard recently shared his thoughts on Billy Maximoff's future within the MCU. The actor was first introduced in WandaVision, a limited series that focused on Wanda Maximoff (Elizabeth Olsen) dealing with her pain following the loss of Vision (Paul Bettany). Through her anguish, Wanda inadvertently used her powers to take over a small town, controlling the lives of the people around her and shaping her environment to resemble to that of a series of sitcoms. During the course of the show, she manifested her twin sons, Billy (Hillard) and Tommy (Jett Klyne).

Billy and Tommy had a brief appearance in the MCU's most recent film Doctor Strange in the Multiverse of Madness, solely existing in the Earth-838 alternate universe. There, the two were flesh and blood and lived a relatively peaceful life with their mother. However, since their existence is in a separate reality, this has left many wondering if the two will ever reappear in the main MCU universe.
