VisionQuest just flipped Jocasta’s Marvel origin, and that changes Ultron too

VisionQuest has taken an Avengers character in a very different direction. Episodes 3 and 4, "Reboot" and "Malware," reveal that Butcherbird is Jo Carrington, also known as Jocasta, and the show rewrites her comic book backstory in a way that immediately changes her connection to Ultron.

A different Jocasta arrives in VisionQuest

Spoilers for VisionQuest Episodes 3 and 4 follow.

The change lands inside the show’s latest storyline, which briefly shifts attention away from Paladin and toward a string of killings tied to Butcherbird. Those deaths surface in news reports, and Ultron is the one who pushes Vision to pay attention after they realize the victims were all board members of Markridge Biotech, the company responsible for creating the first synthetic consciousness.

Vision, Tommy Shepherd and the other AIs head to a gala in an attempt to protect the remaining founder, Katarina Wells. Instead, the attacker is revealed as Jo Carrington, operating as Jocasta. Ultron then talks his way into taking control of Vision’s body because Vision is not equipped for the fight. Katarina Wells is killed, despite Vision’s stated mission, and Jocasta repeats a phrase audiences already know from Avengers: Age of Ultron, invoking Ultron’s line about "peace in our time."

That reveal is where the major Marvel change takes effect. In VisionQuest, Jocasta is not presented as a synthetic being created to be Ultron’s wife or love interest.

Why the rewrite matters

In Marvel Comics, Jocasta was introduced in 1977 as a character Ultron intended to make his bride. Her mind patterns were based on Janet Van Dyne, and her origin was tied directly to Henry Pym, Janet and the Avengers. She ultimately rejected Ultron and aligned with the Avengers, but that original setup kept her story rooted in his plans.

VisionQuest replaces that history with something darker and more independent. The show suggests Jo Carrington’s consciousness was forced into the Jocasta synthetic by the other founders in order to get the result they wanted, regardless of the damage to her psyche. Her killings are framed as revenge against the people who did that to her, and the series does not show much remorse from her.

For MCU fans, that means the character no longer arrives with built-in programming to love Ultron, rebuild him or borrow an Avenger’s moral compass. It also pushes Jocasta further away from the Pym and Van Dyne-centered version from the comics. The immediate effect is a new dynamic between Ultron and Jocasta, with neither fitting the old Bride of Ultron role, and a bigger opening for VisionQuest to keep building stories around synthezoids and embodied AI.
