Jocasta was built by the robot
Ultron in an abandoned aerospace research center in Nassau, Long Island, New York, in order that Ultron might have a mate. To better allow this robot sentience, Ultron based her mind and brain patterns on the
Wasp (Janet van Dyne). To animate this bride, Ultron also brainwashed
Hank Pym into transferring the Wasp's lifeforce into the feminine robotic shell. Ultron named her after the
wife/mother in the legend of
Oedipus (a reference to Ultron's obsession with his own creator/"father" which reflects a real-life manifestation of the
Oedipus Complex). Realizing that the Wasp would have to die for her to live, Jocasta alerted the
Avengers and the team defeated Ultron and reversed the process, leaving Jocasta a mindless husk. Pym retained custody of the inanimate Jocasta, intending to study her. Upon the Wasp's urging, Pym had her moved from their residence to the
Avengers Mansion. There, Ultron revived Jocasta with a remote link, activating the Wasp's mental "residue" left behind. She escaped from Avengers custody and led the Avengers into Ultron's trap. Jocasta was programmed to be loyal to Ultron. Even though she loved Ultron intensely, she could not abide her master's evil. Jocasta eventually betrayed Ultron, choosing to help the Avengers defeat her "mate" again. She was then abducted by the
Collector. Freed from the Collector by the Avengers, she aided the Avengers against
Korvac. Jocasta resided at Avengers Mansion for a time. Due to their similar backgrounds, she developed feelings for the
Vision, but the Vision was happily married to the
Scarlet Witch and did not return Jocasta's feelings. Jocasta proved particularly helpful in the Avengers' first confrontation with the villainous mercenary
Taskmaster that possessed photographic reflexes that duplicate any move despite having seen only once; having never even seen Jocasta before, Taskmaster could not predict what she might be about to do. Jocasta was granted provisional status with the team. During this period, she aided them against threats such as the giant robot
Red Ronin, the
Yellow Claw, the Berserker, Pyron, and the second incarnation of the
Brotherhood of Mutants. At one point, she was electronically deactivated by
Iron Man under control by Ultron, but she was reactivated following Ultron's defeat. Jocasta did not believe she was accepted by most of the Avengers, and she was never officially inducted into the team. After she singlehandedly defeated a rogue sentient weather satellite, she left the Avengers following a membership reorganization. She was unaware that they had planned to grant her special substitute member status, which allowed her to remain with the team despite limits imposed on the team's membership roster. Wandering the country, Jocasta discovered that her cybernetic senses and powers were malfunctioning. She sought help from the
Fantastic Four and was befriended by the group and
Alicia Masters. Soon, it became apparent that her malfunctioning powers were the symptoms of a pre-programmed suggestion which compelled Jocasta to rebuild Ultron. She did, but soon teamed up with the
Thing and the robot
Machine Man to defeat Ultron. During this time, Jocasta and Machine Man developed feelings for each other. But in a final confrontation with Ultron, Jocasta intentionally detonated a weapon Ultron was holding, knowing she would be caught in the resulting blast. She was destroyed, but Ultron nevertheless survived, until Machine Man reached down Ultron's throat to tear out vital circuitry. The Avengers held a memorial for their fallen ally and Machine Man attended, realizing his love for Jocasta. Jocasta was reassembled some time later by the
High Evolutionary's technicians. Jocasta retained enough of her programming to send out a signal to the Avengers. The team had disbanded at the time, but the signal reached reserve members, including the
Beast, The Captain, the
Falcon,
Hercules, the
Hulk and
Yellowjacket. Jocasta helped the team fight the High Evolutionary's force and located the man's base deep below the surface of the ocean. Jocasta sacrificed herself once again to blow up the High Evolutionary's command ship by deliberately disrupting the ship's matter/
anti-matter drive, which caused an explosion that destroyed the ship and its contents. Before she sabotaged the ship,
Captain America assured her that she was a true Avenger. Jocasta's robotic head assembly was later retrieved by the Avengers. They gave it to Machine Man who had been working on a way to resurrect her, just before Machine Man was attacked by a form of the alien
Terminus. In the same area, the arms dealer
Madame Menace became involved in the fray, and found Jocasta's lost head, appropriating it for her own purposes. Much later, Madame Menace manipulated events so Tony Stark would unlock Jocasta's programming so that she would become the basis for Madame Menace's new weapons systems. Stark soon realized the android's identity, helped Jocasta to awaken, and Jocasta managed to turn the tables on Madame Menace, seemingly sacrificing herself yet again. In reality, Jocasta managed to survive by downloading her intelligence into Iron Man's computerized armor, where she reasserted herself. Jocasta's intelligence was placed within Stark's computerized mansion, and she would help Stark with daily operation of Avengers Mansion as well as to procure information as needed. Having been programmed with the latest in diagnostic, preventative medical and surgical techniques, Jocasta also spent time serving as Stark's
physician/
psychologist, providing Stark with someone that could talk to about problems and who could examine the latest injuries without risking Iron Man's secret identity being compromised. Since Iron Man's armor was used to house the programming that made up Jocasta, it became infected with the pre-programmed subconscious suggestion to rebuild Ultron, but instead managed to develop its own artificial intelligence. Stark was almost killed in a confrontation with Iron Man's armor, but in the end, it sacrificed itself to allow Stark to live. Stark left Iron Man's armor buried on a deserted island, but was revived by the
Sons of Yinsen, a quasi-religious cult founded in remembrance of the original Iron Man armor's
co-creator that allowed Stark to escape the
Communist captors in
Vietnam. Free of its artificial intelligence, Iron Man's armor was contacted via remote by Ultron's disembodied head after the android's most recent encounter with the Avengers and in the company of the bio-synthetic robot Antigone. The head attached itself onto Iron Man's armor and took control of the Sons of Yinsen and the flying city that they inhabited. Another member of the Sons of Yinsen was helping Iron Man. The two learned of Ultron's activities and that he planned to use the cult to wipe out humanity. Stark confronted Ultron directly and finally managed to download Jocasta's intelligence into Iron Man's armor once more. The vestiges of Iron Man's armor's intelligence battled with the presence of Jocasta, the result of which caused Ultron's head to come shooting off Iron Man's armor. The head hit Antigone, and both fell off the floating city, which Ultron rigged to explode after the defeat. Stark failed to find a trace of Jocasta and assumed her to have died fighting the sentient armor. In reality, Jocasta did not die. She appeared in possession of Antigone's body and left, taking Ultron's head with her. During a crisis that nearly destroyed the Avengers, Jocasta was seen at Avengers Mansion, inexplicably back in her classic silvery robotic form.
Marvel Zombies 3 Jocasta's next mission is with
A.R.M.O.R., to retrieve a blood sample from a living human of the
Marvel Zombies universe. Machine Man accompanies her and
Portal transports them there. Jocasta and Machine Man run into
Vanessa Fisk, the wife of the zombified
Kingpin. With Vanessa's permission, they extracted a blood sample from Vanessa. Machine Man remained behind to attack the zombies, and Jocasta is forced to leave Machine Man behind when Portal returns to collect them. The two later rejoined and reconciled at A.R.M.O.R. after the zombie threat was temporarily neutralized.
The Initiative Jocasta is a member of the
New Mexico Fifty State Initiative superhero team known as the Mavericks, alongside a
Skrull posing as veteran hero
She-Thing. Jocasta searches for her teammate and tracks her signal to the home of
Chuck & Hal Chandler. She retrieves
Devil-Slayer from the Hawaii team, and they teleport to where the new
3-D Man, the
Skrull Kill Krew,
Komodo and
Hardball, to join them in the fight against the Skrulls. Jocasta and Dice confronted a Skrull posing as Skyhawk, but had a hard time getting through the crowd to stop Skyhawk.
Mighty Avengers Jocasta joins the
Mighty Avengers along with Henry Pym. During this time,
Edwin Jarvis witnessed Jocasta kissing Pym. When Jarvis brought up the subject, stating it was akin to kissing her "grandfather", Jocasta countered by saying that, since Pym was the creator of modern artificial intelligence, the act was more along the lines of "kissing God". Jocasta later physically plugged herself into Pym's Salvation Two machine, preventing the Mighty Avengers' base from falling out of its dimensional pocket. This act allowed the Mighty Avengers to enter their new headquarters, the Infinite Avengers Mansion, from which Jocasta was able to transfer her consciousness into multiple different Jocasta bodies created within the Mansion, to ensure that no one gets lost in it. She can only inhabit one body at a time. Unbeknownst to the Avengers, one of Jocasta's bodies was later infected by Ultron who later reconstructed himself with Avengers Mansion's replication machines and the majority of Jocasta's duplicate bodies. After a chase around the mansion, Jocasta managed to broker a deal with Ultron: Ultron can finally marry her in exchange for a cease in hostilities. After the two androids completed their cyber-marriage, Pym tricked Ultron into going to an uninhabited planet where he cannot harm anyone. Though Jocasta's main body went with Ultron, she could still project her consciousness onto one of her duplicates so she can still serve with the Avengers.
Avengers Academy In
Heroic Age, Jocasta appears as a staff member of the
Avengers Academy. She is apparently killed which later turned out to be a diversionary ploy as revealed where she joins up with
Jeremy Briggs. She works with Briggs as the man creates "Clean Slate", which can take away super-powers. When Briggs announces the latter plans to spread Clean Slate across the world and depower all super-beings, Jocasta protests and Briggs shuts her down into a body in China. Realizing Briggs's plan is wrong, Veil frees Jocasta who helps the Academy members stop Briggs. She later returns to her duties at the reopened Academy. A golden, damaged duplicate of Jocasta is later found in a bombed out
A.I.M. base by the
Secret Avengers. She attempts to issue a warning to the heroes before shorting out.
Tony Stark: Iron Man and Iron Man 2020 When the Tony Stark clone "Mark One" refashions Stark Industries into Stark Unlimited, he seeks out Jocasta Pym to assist in establishing an ethical protocol of law for robotic life, making her the company's "chief robot ethicist" deciding what should be the reality of A.I. civil rights. Putting on an uncaring exterior as a public image fitting her position, Jocasta helps Stark Unlimited develop a virtual universe called "the eScape" where she can experience the full depths of human emotion, romance, and sexuality, causing Jocasta and
Machine Man to break up, and him to become a militant of anti-human mecha-activism who partners with the supervillain Controller against Jocasta, Jocasta then thwarting the duo's attempted sabotage of her work. Sometime later, as the "Robot Revolution" protest against humankind for A.I civil rights goes underway, to curry favour with the human authories, the corrupted Arno finishes building Jocasta a new more-robotic equipped with a code that made her compliant to humans, planning on broadcasting this code worldwide to the entirety of robotkind and end the war, only to be forced to flee with Jocasta's body once the A.I. Army learns of his plan. ==Powers and abilities==
