The Marvel Comics history of 'Visionquest's Butcherbird Killer

At each crime scene, the Butcherbird killer has removed key biological components from each victim, like blood or an eyeball. All the murdered scientists were part of the same think tank group that, decades earlier, pioneered breakthroughs in AI technology. The one scientist missing from this targeted group is Josephine Carrington, played by T’Nia Miller. And that’s because Jo Carrington died in 2008. Vision believes that this robot murdering scientists contains an AI mind “based” on Carrington. But when they meet, she tells him, “I’m not based on her, I am her.” It appears Carrington uploaded her mind into a robotic body. It is a body which, in Marvel Comics, became Jocasta. In the comics, Jocasta was a tad bit friendlier.

The Marvel Comics History of Jocasta, the Second Android Avenger

Writer and former Marvel EIC Jim Shooter and artist George Perez created Jocasta, and she first appeared in Avengers #162 in 1977. The villainous AI Ultron, one of the Avengers’ most lethal foes, designed her as his “bride,” a companion who presented as female. Together, he hoped they’d conquer the human world. Ultron used the brain patterns of heroine Janet Van Dyne, the Wasp, to give Jocasta sentience. Ultron constructed Jocasta’s body out of titanium steel. And her gave her almost identical abilities to Ultron’s other creation, the Vision, in terms of powers and computer capacity.

Unfortunately, when Jocasta realizes that her full actualization would lead to the Wasp’s death, she rebels against her maker. She helped the Avengers defeat Ultron, and became an unofficial member for several issues. Jocasta developed feelings for the Vision (who was technically her brother), but he was married to the Scarlet Witch at the time. Leaving the Avengers heartbroken, she wandered the world for many years, occasionally helping her old teammates in times of need. Sometimes, she teamed up with other heroes, like the Thing from the Fantastic Four.

Jocasta in the Modern Marvel Universe 

In more modern Marvel Comics, Jocasta joined Hank Pym’s Mighty Avengers team, and they even had a brief flirtation. This was, let’s just say, a bit awkward, as Jocasta’s personality was based on that of Pym’s ex-wife, Janet Van Dyne. To add another layer of ick, Ultron’s creator, Hank Pym, the first Ant-Man, was technically her grandfather. Given that her name is a reference to Jocasta of Greek mythology, who married her son Oedipus, it makes some kind of sense. She later became a staff member at the Avengers Academy. She still pops up from time to time, aiding the Avengers during dire world-ending threats.

The MCU Future of Jocasta in VisionQuest and Beyond

In the MCU, Jocasta is not based on the brain patterns of Janet Van Dyne. Instead, her robotic body houses the mind of AI pioneer Jo Carrington. She somehow transferred her consciousness into that of the robot before dying of an undisclosed illness. The “how” and “why” of all that remains a mystery. She came looking for the final living scientist from her group, Katerina Wells (Mary McDonnell), to retrieve a biological component from her before enacting her revenge. But Ultron, in Vision’s body, tricks her into disintegrating Wells before she could. Will she join together with Ultron? Or will she become a hero, as she did in the comics? We’ll have to wait and see how VisionQuest continues to unfold.
