VisionQuest will show you an 'older and more mature' but still dangerous Ultron, star says

James Spader, who plays Ultron in Marvel's WandaVision television series, has revealed details about the older, more mature, yet still dangerous version of the character that fans can anticipate. Spader shed light on how Ultron has evolved during the 12-year gap since his last appearance in the Avengers: Age of Ultron movie. Despite being destroyed by Vision, Ultron has returned to life, possessing a copy of his source code stored in Vision's quantum processor.

Throughout VisionQuest, Ultron will be portrayed as a human avatar, enabling him to observe events and humanity through Vision's perspective. As Vision delves into questions about his identity and purpose in his Disney+ show, Ultron will serve as one of the many artificial intelligences that Vision will seek guidance from. In the final part of Marvel's WandaVision trilogy, Spader's Ultron has matured, becoming more sophisticated and cautious.

While still possessing a touch of childishness and wit, his humor and intellect are significantly more advanced than in his earlier MCU appearance. However, Spader maintains that the inherent danger and looming threat that Ultron exhibited in Age of Ultron remain a constant presence.
