Marvel Studios confirmed at San Diego Comic-Con that VisionQuest, the Disney+ series centred on Paul Bettany's Vision, will premiere on 14 October, making it the final release before Avengers: Doomsday. As the concluding chapter of a loose trilogy that began with WandaVision and continued with Agatha All Along, the show represents the franchise's last opportunity to address how Vision has processed the death of Wanda Maximoff, the Scarlet Witch, who died at the end of Doctor Strange in the Multiverse of Madness.

WandaVision explored Vision and Wanda's romance, complicated by Wanda's magical enslavement of Westview to resurrect a version of him after his death in Avengers: Infinity War; that Vision was eventually rebuilt with his original memories but not his emotions. Star Paul Bettany has said the new series follows White Vision's struggle to reconnect emotionally with those memories, and the plot will bring him face to face with Ultron (James Spader) and an adult version of his "son" Tommy (Ruaridh Mollica). With showrunner Terry Matalas at the helm, the article argues VisionQuest must directly confront Vision's reaction to Wanda's death to resolve this long-standing emotional thread before Doomsday.
