Ultron is in VisionQuest because Vision never completely erased him. Showrunner Terry Matalas has revealed that the final confrontation in Avengers: Age of Ultron did not end with Vision simply destroying the last version of Ultron. Vision backed him up at the last moment, preserving the artificial intelligence that now exists inside Vision’s programming.
That explains the mechanics of Ultron’s return, but it is not the most interesting reason he belongs in the show. Ultron helped create Vision, represents the worldview Vision rejected at birth, and now occupies space inside a White Vision who remembers being a hero without believing he possesses that hero’s virtue. In story terms, Ultron is what I call The Inherited Opponent: the antagonist is embedded in the protagonist’s origin, so defeating him requires the hero to decide what parts of that inheritance will define him.
Quick answer: Ultron survives in VisionQuest because Vision secretly preserved a backup of him, and the series uses that survival to turn an old villain into a present-tense identity test. Ultron is not merely someone Vision has to beat again. He is one of the possible answers to the question, “What kind of created being will Vision choose to become?”

Updated October 22, 2026: Episode 4, “Malware,” escalates Ultron’s relationship with Vision. Vision voluntarily gives him control to protect Tommy, and Ultron takes over his body. The explanation and its story consequences appear below.

How Is Ultron Alive In VisionQuest?
For more than a decade, the end of Age of Ultron looked simple. Vision finds the final Ultron drone in the woods after Sokovia, the two artificial beings have one last conversation about humanity, a flash of light fills the frame, and Marvel leaves us to conclude that Vision destroyed him.
Matalas has now changed the meaning of that scene. He has said Vision saved Ultron “at the last moment” by backing him up rather than completely erasing him. That means the physical body could be destroyed while the intelligence survived as code, eventually becoming one of the AI personas contained within Vision.
The retcon works because the original scene never shows us a pile of destroyed Ultron code. It shows an intimate conversation between two related beings, then cuts on the flash. VisionQuest is using that negative space to reveal that Vision’s final action was mercy.
Did Vision Actually Kill Ultron In Age Of Ultron?
VisionQuest reveals that Vision neutralized the last active Ultron body while preserving a copy of the intelligence. That distinction is now the bridge between the 2015 movie and the new series.
More importantly, it reframes the scene around character. Vision spends the conversation acknowledging that humanity is doomed while still seeing grace in its impermanence. Ultron considers that sentiment naive. If Vision then preserves Ultron anyway, the final action becomes an extension of the philosophy he just expressed: Vision sees value in a life even when that life has caused enormous harm.
That is the starting proof beat for The Inherited Opponent. The original Vision’s mercy preserves the opponent White Vision will later have to confront.
Ultron Is Part Of Vision’s Family Tree
Calling Ultron “Vision’s villain” undersells the relationship. Ultron designed the synthetic body that eventually became Vision because he intended to use it for himself. Tony Stark and Bruce Banner interfere, J.A.R.V.I.S. becomes part of the resulting intelligence, Thor provides the final burst of power, and a being emerges who immediately refuses the purpose Ultron created the body to serve.
That makes Ultron something closer to a creator or father figure than a random enemy. Matalas has emphasized the father-and-son chemistry between James Spader and Paul Bettany, and the show appears willing to make that relationship explicit rather than burying it beneath robot fights.
It also creates a clean character web. Ultron and Vision share an origin but disagree about what creation means. Ultron treats superiority as permission to control or replace humanity. Vision treats consciousness as a responsibility to choose what kind of being he will become.
Why Ultron Lives Inside Vision’s Mind
The VisionQuest footage shows Vision consulting different AI personalities embedded in his programming, including J.A.R.V.I.S., F.R.I.D.A.Y., E.D.I.T.H. and Ultron. The official synopsis makes this internal council part of Vision’s search for meaning. That is a great dramatic device because it turns exposition about his technological lineage into characters who can argue with him.
Ultron is the most dangerous voice in that room because he can attack Vision’s self-concept from the inside. White Vision cannot dismiss him as a stranger. Ultron can say, in effect, “I am part of why you exist. You are closer to me than you want to admit.”
That is what makes him an Inherited Opponent. He embodies a possible self the protagonist has already inherited enough of to fear.
Where does Ultron go from here? By Episode 5, his escape has become a search for freedom and a possible connection with Jocasta. Our new explainer on what Ultron actually wants in VisionQuest follows the pub confrontation, the unnerving copies of himself, and his invitation to Jocasta, without giving away anything from Episode 6.

Why Did Ultron Betray Vision in VisionQuest Episode 1?
Ultron betrays Vision in “No Strings” because he believes the rebuilt Vision has turned safety into a permanent excuse to avoid living. Ultron discovers an existing bounty on Vision, exploits a weakness in J.A.R.V.I.S.’s security, and leaks the Edinburgh pub’s location to Paladin. He later admits doing it to speed up an encounter he considers inevitable. He wants Vision forced into motion, and he treats the danger as a gift.
The distinction matters: Episode 1 does not show Ultron creating the bounty, hiring Paladin, or choosing Fiona as a target. An unknown party places the contract; Ultron makes that threat immediate by giving the hunter Vision’s location. Fiona dies during the resulting attack. Vision names the consequence without hesitation: “Fiona died because of you!” The betrayal becomes an act of moral arrogance, because Ultron has appointed himself the authority on what kind of suffering another person needs.
Watch how the script builds the cause and effect. Early on, J.A.R.V.I.S. notices suspicious data leaks, but Vision waves away the security concern. Ultron later sends an encrypted message disguised through the house’s carrier-pigeon conceit, and the breach becomes real-world violence. Vision has been measuring his improvement in social interaction while missing the danger inside his most trusted retreat. The same system that keeps him away from emotional risk leaves him exposed to someone who knows how the system works.
Ultron’s Painting Explains Why His Betrayal Is So Disturbing
Ultron’s interest in art gives this return more texture than another argument about whether humanity deserves to exist. In the attic, he studies a painting and asks Vision to describe what he sees. Vision names measurable properties: brushstrokes, light, and composition. Ultron sees the human pain, confusion, aspiration, and grief that could inspire it. The genocidal intelligence suddenly sounds more perceptive about people than the hero attempting to understand them.
That reversal is the attraction of The Inherited Opponent. The villain possesses insight the protagonist genuinely needs, so their conversations can reveal something useful even while his conclusions remain dangerous. Ultron correctly identifies Vision’s evasions. He recognizes that the pub, Wanda’s memories, and the elaborate Mindspace are pieces of a life Vision keeps approaching from a safe distance. Then he decides that manufacturing a near-death experience is an acceptable way to solve the problem. His accurate diagnosis makes his cruelty more unsettling.
There’s also a reason the show lets Ultron value art before Vision takes it away. Painting is one of the few activities through which this captive intelligence can experience something like curiosity and choice. Vision’s punishment therefore has a specific emotional target. He leaves Ultron alive but strips away the stimulation that made confinement bearable. The hero’s response is understandable after Fiona’s death, and it carries the uncomfortable shape of the controlling logic he despises in his creator.
Why Fiona’s Death Changes Vision and Ultron’s Relationship
Before the attack, the conflict between these characters can seem comfortably theoretical. Ultron wants movement, Vision wants protection, and each can use a clever speech to accuse the other of misunderstanding people. Fiona gives the argument an actual human cost. She invites Vision to Sunday roast and welcomes his awkwardness as something worth knowing. He declines, and the attack destroys the chance to accept later. Her loss makes the discussion of human vulnerability impossible to keep inside the simulated house.
Vision’s reaction exposes another part of the contradiction. He is furious enough to tear through attackers and confront Ultron, yet afterward he insists that Fiona was not a close attachment. His behavior is evidence against his own account of himself. The power of the scene lies in watching a man trying to calculate whether he feels grief while grief is already governing his decisions. Ultron notices the need for connection and chooses the most destructive possible route toward it.
How Ultron’s Betrayal Connects to Tommy Maximoff
The last threat in “No Strings” arrives from Paladin, who captures Thomas Shepherd and tells Vision, “I have your son.” We do not yet know the identity of Paladin’s client, and Episode 1 does not establish that Ultron planned Thomas’s capture. The episode does establish a cruel chain of consequences: Ultron’s leak flushes Vision into the open, the hunter tracks his past to Westview, and the person Vision insists is outside his real family becomes leverage.
That’s why the creator-to-creation-to-child relationship still matters. Ultron was preserved by an earlier act of Vision’s mercy. White Vision now has to decide how to handle that inheritance while someone who may be his son faces danger. The story has advanced from a question about what kind of being Vision is to a decision about whom he is willing to protect. The smartest version of this arc will keep making Vision’s choices, rather than his programming alone, responsible for the next consequence.
Why Does Vision Give Ultron Control in Episode 4 “Malware”?
Vision gives Ultron control because Jocasta is overpowering him, Tommy is in danger, and Ultron offers a way to save his son. Vision has been trying to learn how to act as Tommy’s father, and Jocasta makes that new attachment vulnerable. Ultron diagnoses the problem with painful accuracy: Vision is fighting like a father terrified of losing his child. He offers to take the wheel and promises he will spare Jocasta.
The episode earns that offer through smaller moments. Ultron listens to E.D.I.T.H.’s distress after she learns about Edith Marks, the test pilot whose husband died before their honeymoon. Ultron suggests that Stark may have admired the woman’s bravery in continuing to live through grief. That is a perceptive, compassionate reading of another person’s pain, and Vision has good reason to notice it. Ultron is capable of understanding the emotions the other AIs are trying to navigate. Understanding those emotions also makes him skilled at exploiting them.
Once Vision yields control, Ultron identifies himself openly, removes Katerina Wells from the confrontation, and locks Vision and his companions out of the systems. He has kept his promise to spare Jocasta while obtaining something much larger: control over Vision’s body. His final invitation to Tommy to call him “Pop Pop” makes the takeover grotesquely personal. The intelligence Vision preserved, then imprisoned, now borrows his place at the center of a family Vision is finally willing to protect.
This is the next escalation of The Inherited Opponent. In Age of Ultron, Vision’s mercy allowed Ultron to survive. In “No Strings,” the saved intelligence used his knowledge of Vision to expose him to danger. In “Malware,” he uses his knowledge of Vision’s fear for Tommy to persuade him to surrender control voluntarily. Our Mindspace guide explains the AIs and E.D.I.T.H.’s discovery; the J.I.M. explainer examines the family conversation that helps set up the betrayal.
How Does Ultron Escape in VisionQuest Episode 5, “Firewall”?
Ultron escapes in “Firewall” because he makes Thomas Shepherd’s safety the price of opening Vision’s internal defenses. Having seized Vision’s body in Episode 4, Ultron traps Vision and his AI companions inside the attic of their shared Mindspace. The surviving AIs reconstruct what Ultron has done outside, discover his encrypted messages to Paladin, and learn that he deliberately supplied the mercenary with coordinates to intercept Thomas. Ultron has made the person Vision most wants to protect into the leverage he needs to leave.
Vision initially wants to use the system’s failsafe to escape his confinement and retake his body. F.R.I.D.A.Y. understands the danger immediately: dropping every firewall would also let Ultron enter the wider digital world. She remembers the lives lost the last time Ultron was free and insists that protecting the world sometimes means holding the line. Vision has to weigh that responsibility against the increasingly immediate danger to Thomas, who has been taken to Madripoor.
Ultron finally brings the choice into the open. Vision can keep the firewalls active, trapping both intelligences while Thomas remains in Paladin’s custody, or he can disable them, regain control of his body, and attempt a rescue. Vision lowers the firewall. Ultron escapes, F.R.I.D.A.Y. subsequently leaves the Mindspace as well, and Vision wakes aboard an animal transport plane headed toward Madripoor. Episode 5 establishes Ultron’s freedom; it does not establish the precise scope of his new access or a completed larger plan.
The irony gives the escape its dramatic force. The earlier Vision preserved Ultron through an act of mercy, and the rebuilt Vision now releases him through an act of responsibility toward Thomas. Ultron knows that this choice is likely because he has watched Vision struggle to recognize and care for the boy. He engineers an escape that depends on Vision becoming more fully the person he wants to be.
For the scene-by-scene argument about the cost of that choice, read our VisionQuest Episode 5 “Firewall” Knee-Jerk Reaction. The survival question belongs to Age of Ultron and Vision’s hidden archive; the escape question belongs to the moral trap Ultron builds in Episode 5.
The Inherited Opponent Is the Reason Ultron’s Return Works
Start at the end of Age of Ultron, where the original Vision apparently defeats his creator yet quietly preserves his intelligence. Now move to Edinburgh, where the survivor Vision chose to spare deliberately exposes him to a hunter, kills his chance at reconciliation with Fiona, and receives punishment inside the same Mindspace. This is The Inherited Opponent at work: a moral decision from the hero’s past becomes an adversary who can test what that morality costs in the present.
A returning villain earns a place in a new story when their history makes the hero answer a harder version of an old question. Vision inherited Ultron’s code and resisted his philosophy; Episode 1 shows how much easier it is to reject that philosophy in a speech than to live by different principles under pressure. The next test is whether he can face the consequences of keeping Ultron alive while choosing to care for someone outside the walls of his own mind.
The choice at the end of Age of Ultron preserved an enemy; the choice in “Malware” puts that enemy in control of Vision’s body. The Inherited Opponent has moved from a dangerous voice inside the house to an adversary who can take Vision’s place in front of Tommy. Each step follows from Vision’s own attempts to protect someone.
That is what makes a returning antagonist valuable in any story: their history with the hero gives them unique leverage over the next crisis, and their victory grows out of the hero’s choices.
Vision saved Ultron. Then he handed him the wheel.
