We've known for several months that Joe Locke will play Wiccan in Agatha: Coven of Chaos, but it appears Marvel Studios has plans for Billy Kaplan beyond the WandaVision spin-off.
According to scooper Daniel Richtman, a TV series revolving around Wiccan was in the works prior to the WGA strike. No additional details have been shared, though this would be the third series to spin out of the Phase 4 title after Agatha: Coven of Chaos and Vision Quest.
Billy is, of course, Wanda Maximoff and The Vision's son. Alongside his twin brother, Tommy, they were wiped from existence when the Scarlet Witch took down the Hex surrounding Westview in WandaVision.
While comic book fans will know their teenage counterparts as Young Avengers Wiccan and Speed, it's not like they somehow survived and just grew up after fading into nothing. On the page, when Wanda lost her children (after similarly creating them with her Chaos Magic), their souls inhabited Billy Kaplan and Thomas Shepard.
So, they both are and aren't the Avenger's kids, but thanks to their "mother," the reincarnated twins were granted incredible powers.
We'd assume something will happen that leads to Agatha tracking Billy down in Agatha: Coven of Chaos. Perhaps she wants his abilities for herself or hopes to train the boy. Either way, there are currently no confirmed plans for Speed but we do expect Wiccan to be a potential game-changer in the MCU.
Assuming this project actually becomes a reality, bet on it revolving around Wiccan finding his brother and perhaps even tracking down the Scarlet Witch in a loose adaptation of The Children's Crusade. That's something we've heard rumblings about for a good year or more now.
We'll see what happens, but this sounds more like a Special Presentation rather than a TV show. Disney CEO Bob Iger is looking to cut back on streaming content to avoid any future dilution of the MCU brand so there's every chance this spin-off will ultimately fall by the wayside.
