Apart fromWandaVision, Billy’s Wiccan costume was also teased inDoctor Strange in the Multiverse of Madness' final battle, where a Wiccan statue in the Scarlet Witch temple atop Mount Wundagore foreshadowed the hero’s arrival.

Wiccan’s Costume Shows How Good Superhero Costumes Are Designed
Billy’s Wiccan costume effectively reinforces the connection between Joe Locke’s Billy and Elizabeth Olsen’s Scarlet Witch. AlthoughScarlet Witch doesn’t appear inAgatha All Along, Billy’s quest to learn about his previous life and his complicated alliance with Agatha Harkness contributes to Wanda Maximoff’s MCU story in her absence. The Scarlet Witch and Vision references in Billy’s Wiccan costume are a beautiful extra touch, as they prove that Billy treasures the memory of his parents even after reincarnating.
