Seeking a bride, Ultron kidnapped the Wasp, brainwashing her then-husband and Ultron's creator, Henry Pym (Ant-Man), into transferring her life energies into a newly built robot: Jocasta. Jocasta acquired the Wasp's personality, emotions, conscience, and ability to control insects, but not her memory. Realizing that the Wasp must die for her to live, Jocasta used that cybernetic insect control to summon the Avengers, who stopped Ultron and reversed the transference, saving Jan but shutting down Jocasta. Unknown to the Avengers, Jocasta still retained some portion of the Wasp's essence, but she remained inert until activated from afar by Ultron. Battling free of the Avengers, Jocasta returned to Ultron's side but quickly realized he was irrevocably evil and aided the Avengers against him. After Ultron's defeat, Jocasta and several Avengers were kidnapped by the Collector; the remaining Avengers soon freed Jocasta and the others, learning of the oncoming universal threat of Korvac in the process. Jocasta aided the Avengers against Korvac, her cybernetic senses detecting vital clues that helped to locate him. When the government soon forced the Avengers to contract to only seven members, Jocasta remained with the team, self-deprecatingly identifying herself as a "mere machine" and thus not subject to the group's size limits.
Jocasta attempted to bond with individual Avengers, but continually felt shut out. Even the android Vision, who was having emotional problems of his own, repeatedly ignored Jocasta. Having nowhere else to go, she remained with the team and aided them against Django Maximoff and the Taskmaster; after defeating the Taskmaster, Captain America and Iron Man offered to make her a full Avenger at the next business meeting. However, Jocasta remained a probationary member while aiding the team against Red Ronin and assisting in Ms. Marvel's delivery of the child Marcus. When Ultron next threatened the Avengers, he recognized Jocasta as a prime threat and mind-controlled Iron Man into disabling her, but she restored herself with the aid of Edwin Jarvis and continued to aid the team against the Yellow Claw, Pyron, the Leader, the Shadow Lord and the Berserker, and the Brotherhood of Evil Mutants.
Jocasta never received her promised status as a full Avenger, and only learned from Jarvis of an emergency meeting called about the threat of the Weathermen. After Jocasta single-handedly faced the power behind the Weathermen, the rogue sentient weather station Samarobryn, the Avengers held a meeting to determine their new membership that same afternoon, and again Jocasta was apparently forgotten. Jocasta wordlessly left the team (who had intended to offer her a lesser "substitute" status with them). Her metallic skin preventing her from fitting into society, Jocasta was rejected by humanity and retreated from all contact with people until her cybernetic senses began to malfunction. The Fantastic Four discovered the cause of the malfunction was an attempt by Ultron to resurrect himself, and the Thing and Machine Man came to Jocasta's aid. Though Machine Man and Jocasta began to bond as close friends, ultimately Jocasta sacrificed herself in a futile attempt to destroy Ultron.
Seeking inside information about the Avengers, the High Evolutionary recovered Jocasta's parts and reconstructed her. She sent an emergency signal to the Avengers, who came to her aid. Again, Jocasta sacrificed her body to destroy the foe, this time preventing the detonation of a genetic bomb which would have altered mankind. However, Jocasta's head survived the explosion, and her memories and personality remained intact, though dormant. The head was recovered by the Avengers who, unable to do anything with it, transferred her to the keeping of her friend, Machine Man. Working on restoring her, he was interrupted by one of the metal-devouring Termini and fled with Jocasta's head. Both Machine Man and Jocasta were taken to a nearby factory belonging to Sunset Bain (Madam Menace), where Bain covertly duplicated Jocasta's head and returned a sabotaged copy to Machine Man. The head was later stolen by Mechadoom and re-retrieved by Machine Man, who, unaware of Bain's interference, was unable to resurrect Jocasta.
