From “WandaVision” and “Doctor Strange in the Multiverse of Madness” to the spin-off series “Agatha All Along” and the upcoming “VisionQuest,” the Marvel Cinematic Universe has offered several versions of Wanda Maximoff’s (Elizabeth Olsen) and Vision’s (Paul Bettany) twin sons. But how exactly did Billy and Tommy become part of the MCU, and where could their stories lead next? Watch the Looper video above for the complete breakdown.
Billy and Tommy Maximoff first appear in “WandaVision,” where Julian Hilliard and Jett Klyne play the twins. Wanda creates them through her magic while she is using her powers to control the town of Westview. Because they are tied to the Hex, Billy and Tommy vanish when Wanda brings down the magical barrier, taking her imagined version of Vision with them.
That disappearance, however, does not mark the end of their story. A post-credits scene in “WandaVision” shows Wanda hearing the boys’ voices, hinting that Billy and Tommy may still exist somewhere beyond Westview.
Billy and Tommy helped the MCU usher in its Multiverse
The conclusion of “WandaVision” sets the stage for “Doctor Strange in the Multiverse of Madness.” By then, Wanda has fully embraced her Scarlet Witch identity and becomes the film’s tragic antagonist. Desperate to find versions of her sons in another reality, she pursues America Chavez (Xochitl Gomez), whose ability to travel between dimensions could help her search the Multiverse. Wanda’s violent campaign ends only after she sees how deeply corrupted she has become and realizes that the Billy and Tommy of Earth-838 are terrified of her. Released in 2022, the film was the MCU’s first major cinematic exploration of alternate universes, with the twins serving as a key motivation for Wanda’s multiversal journey.
The story becomes even more complicated from there. In “Agatha All Along,” the original Earth-616 Billy Maximoff, now played by Joe Locke, reappears in the body of William Kaplan after Billy’s soul takes over the young man’s body following a fatal car accident. Tommy is reincarnated as well, and “VisionQuest” identifies his new host as Thomas Shepherd, portrayed by Ruaridh Mollica. Across both series, Billy and Tommy begin to understand their abilities: Billy possesses extraordinary magical power that reflects his comic-book identity, Wiccan, while Tommy shares the super-speed powers associated with his comic counterpart, Speed.
With Wanda currently presumed dead in the MCU and Vision working to recover his sense of self in “VisionQuest,” the Maximoff-Visions have become one of the franchise’s most complicated families.
