11 Years Later, The MCU Finally Pays Off A Forgotten Age of Ultron Villain

Since 2019, Kevin Erdmann has been one of Screen Rant's Senior Staff Writers, covering all kinds of Superhero and Star Wars media with Easter egg breakdowns, theory pieces, breaking news, and more. A huge Star Wars & MCU fan, Kevin also loves Batman (because he's Batman), but could talk for hours about why Nightwing is DC's greatest hero. 

With 8 years of total experience covering entertainment and pop culture, Kevin has gotten the chance to interview top creatives and talent, and has also attended major media events like Disney's D23 convention.

Majoring in Cinema Studies with a minor in Comics and Cartoon Studies from the UofO, Kevin lives in Oregon with his wonderful wife, adorable dog, and sinister cat who is no doubt currently plotting his demise.

11 years after 2015's Avengers: Age of Ultron, a forgotten villain tease will finally be paid off in VisionQuest. The third and final chapter of a trilogy of Disney+ shows, including WandaVision and Agatha All Along, the new VisionQuest series will star Paul Bettany as a revived Vision seeking to understand and reclaim his humanity. However, Vision won't be the only advanced AI in the upcoming MCU series.

As seen in VisionQuest's trailers, the upcoming show premiering in October will feature multiple AI characters living within Vision's mindscape, and each of them will have their very own human avatar. As such, the various AI programs living in Vision's mindscape home include FRIDAY, EDITH, JARVIS, DUM-E, U, and James Spader's Ultron, confirming that Vision spared his life and locked Ultron away within his own matrix at the end of 2015's Age of Ultron.

However, the trailers for VisionQuest have also teased the full MCU debut of Jocasta, a forgotten AI who was teased over a decade earlier in the MCU's second Avengers movie.

11 Years Ago, The MCU Teased Jocasta In 2015's Age of Ultron

Jocasta's MCU connection actually goes all the way back to Avengers: Age of Ultron. During the opening sequence, Tony Stark and Bruce Banner discuss the various artificial intelligences available to them while attempting to create the Ultron program.

The movie specifically establishes that Tony has access to multiple AI systems before ultimately settling on JARVIS as the foundation for his technology. After Ultron destroys JARVIS, Tony eventually uses what remains of the AI alongside the Mind Stone to create Vision.

That leaves an interesting gap in the MCU's artificial-intelligence hierarchy. JARVIS becomes Vision, FRIDAY becomes Tony's primary AI, and Ultron becomes the rogue artificial intelligence who wants to destroy humanity. But Jocasta never materializes.

In Marvel Comics, however, Jocasta has a much stranger origin.

Ultron created Jocasta as part of a plan to acquire a mate. He based her artificial intelligence on the brain patterns of Janet van Dyne, the Wasp, making Jocasta effectively an artificial counterpart to one of the people most closely connected to Ultron's creator, Hank Pym.

Jocasta eventually develops her own personality and becomes far more than the obedient creation Ultron intended her to be. Her relationship with Ultron is therefore fundamentally complicated, particularly because she was created from the mind of someone connected to his own creator.

That history gives Jocasta an obvious connection to the MCU's Ultron, even though the movies have never actually adapted it.

Jocasta Is Confirmed To Appear in VisionQuest

After Age of Ultron left Jocasta's existence as little more than an intriguing possibility, VisionQuest appears ready to finally make her part of the MCU's story.

The character can be seen in the trailers for the upcoming series, and her design immediately stands out. Rather than looking like another friendly Stark-style AI, Jocasta appears to have a much more menacing appearance.

Most notably, she looks almost like a female counterpart to Ultron.

That visual similarity could be deliberate. The MCU's Jocasta doesn't appear to be simply a robotic adaptation of the comic character. Instead, her design seems to connect her directly to the same artificial-intelligence lineage that produced Ultron.

That makes her introduction particularly fitting for a Vision-centered story.

Vision himself was created from the combination of JARVIS, Ultron's body, the Mind Stone, and Tony and Bruce's technology. His entire existence is therefore tied to the same artificial-intelligence experiment that produced Ultron.

Jocasta potentially represents another branch of that lineage.

It also gives VisionQuest an opportunity to revisit the central question that has followed Vision since his introduction: what makes an artificial being a person?

WandaVision explored Vision's identity, memories, humanity, and relationship with Wanda. A Jocasta storyline could take that concept in a darker direction by asking whether an AI created from another artificial intelligence can develop an identity independent of its creator.

Will Jocasta Be VisionQuest's Primary MCU Villain?

Everything shown so far makes it increasingly plausible that Jocasta could be one of VisionQuest's major antagonists.

One particularly important detail is that she appears to exist in the physical world rather than simply being another manifestation inside Vision's mindscape. If Jocasta is physically operating in the MCU, that immediately gives her far greater potential as an ongoing threat.

Her apparent connection to Ultron also raises an even bigger possibility.

What if Jocasta isn't simply inspired by Ultron, but is actively connected to him? That becomes even more interesting because Paladin is also confirmed to be involved in the series. There could be multiple foes operating around Vision, potentially leaving Jocasta with her own agenda.

One possibility is that Jocasta wants to free Ultron from whatever remains of his existence. If Vision still contains some trace of Ultron's original consciousness or programming, Jocasta could potentially be attempting to access it.

That would create an especially fitting conflict. Vision has spent years trying to establish himself as something separate from Ultron, while Jocasta could represent the opposite idea: a creation that actively embraces her connection to the artificial intelligence that came before her.

After 11 years, Jocasta finally has the opportunity to become much more than a forgotten Age of Ultron reference.

Whether she's the primary villain or one part of a larger conspiracy, VisionQuest can finally explore a character whose comic-book history has always been intertwined with Ultron, Vision, and the question of artificial identity.

And if Jocasta is secretly trying to bring Ultron back, the MCU may have found its most natural way yet to revisit one of its earliest Avengers villains without simply repeating his original story.

VisionQuest premieres October 14th on Disney+ from Marvel Studios.
