James Spader is back as Ultron in VisionQuest, but the return is tied to something much more profound than another Marvel villain comeback. In the new Disney+ series, Ultron joins Vision's fight to find out who he really is after receiving the memories of the original Vision without the emotions that came with them.
Paul Bettany has described the story as (via Entertainment Weekly):
"Intergenerational digital trauma"
This serves as a good description of the odd link between Ultron, Vision and Tommy Maximoff. Their relationship creates a strange family tree, based not just on fatherhood, but on artificial intelligence and how one creation leads to another.
Spader’s Ultron is particularly crucial as he lives inside the head of Vision, who is trying to figure out his past, his creation, and his purpose. Meanwhile, White Vision remembers Wanda and the Avengers, but not the emotions connected to those memories.
That makes Ultron more than just a returning character. He teams up with Vision on his quest to find out who he is, where he came from, and what kind of man he can become.

James Spader's Ultron connects VisionQuest's strange family across generations
James Spader is all set to come back as Ultron in VisionQuest, 11 years after Avengers: Age of Ultron. But this time, the AI has a very different place in Vision’s story as he will appear inside the android’s mind rather than simply returning as an outside threat.
Paul Bettany says the idea clicked when Terry Matalas suggested bringing Spader back. Once he joined, Bettany saw a three-generation connection taking shape between Ultron, Vision and Tommy, Vision and Wanda’s grown son, played by Ruaridh Mollica.
Bettany summed up the family setup simply:
"Once we had James on board, we had a grandfather, a father, and a son."
That places Ultron, Vision and Tommy in a three-generation chain, with each character representing a different point in Vision’s complicated history. That family idea also connects with VisionQuest's focus on fatherhood and what gets carried from one generation to another.
Here, that legacy is tied to artificial intelligence and creation, rather than being a normal family story.
Ultron's role inside Vision's mind goes beyond a simple villain return

White Vision has settled into a quiet life among humans in VisionQuest, but a bounty changes all that. He's forced into the open, with no choice but to face questions he's been avoiding.
He has the memories of the original Vision, including his life with Wanda and the Avengers, but he’s missing something. White Vision remembers these events, but doesn’t have the same emotional attachment to them, and it’s this difference that makes his identity a core theme of the story.
In an effort to explore that problem, Terry Matalas created a weird world in Vision’s head. It’s like a giant mansion where Vision can alter his surroundings and meet programs that are designed to help him understand his own existence.
Those programs are D.U.M.-E, U, J.A.R.V.I.S., F.R.I.D.A.Y. and E.D.I.T.H. However, Ultron is kept away from them, locked in the attic of the mansion. Bettany, who refers to him as a "psychotic psychotherapist," adds a much darker side to Vision’s search for answers.
It’s that oddity that makes VisionQuest such a daring Marvel project. It’s another "massive swing" like WandaVision, Bettany says, with the story taking an unusual route, not a traditional superhero formula.
VisionQuest will arrive on October 14, 2026 on Disney+
