Ultron is the titular main antagonist of the 2015 Marvel Cinematic Universe film Avengers: Age of Ultron and the deuteragonist of the 2026 miniseries VisionQuest.

He was introduced as a peacekeeping program created by Tony Stark and co-created by Bruce Banner, under experimentation of harnessing Loki's scepter, containing the Mind Stone. Upon gaining sentience, however, Ultron quickly deemed humanity itself as the greatest threat to Earth and attempted to create a new age of technological singularity via humanity's extinction. He is also the creator and arch-nemesis of Vision, the former ally of the Maximoff Twins, Scarlet Witch and Quicksilver, and the second most dangerous archenemy of the Avengers.

After the prototype body destroyed, Ultron constructed the Ultron Prime body with various technology and armaments (see Powers and Abilities below) that not only being more durable than both previous prototype and Ultron sentinels, this body is obviously larger and more complicated in design, especially on the face which enable him to perform various, but limited facial expressions. This body has jet propulsions installed on it, which giving him ability to take flight. The most noticeable traits that this body has are curved antennae, internal torso lighting, and prominent shoulders that heavily inspired by Ultron's own modern depictions as seen in the "Annihilation: Conquest" and "Age of Ultron" comic book crossover series.

Ultron has a personality heavily based on that of his creator Tony Stark, having inherited many of the latter's character traits including his god complex, wit, and sarcasm. Ultron was designed to aid the Avengers and, Stark hoped, what would become eventually become their successor. Unfortunately, Ultron decided that the Avengers and their goals were part of the problem; instead, he planned to effectuate world peace by changing the world, which the Avengers refused to do. Ultron followed a warped version of his protocol to protect the Earth, believing he could do so only if humans were evolved to become more civilized or made extinct to make way for new life if this could not be accomplished.

He is obsessed with perfection via evolution and marvels in anything related to it and despises anything that might challenge it. Because of this he resented the Avengers - especially Stark - as they possessed the resources to help the Earth but kept everything status quo. However, he was aware they "meant well" by trying to protect the Earth but he ultimately saw them as a barricade to prevent humanity's evolution. He also calls them "killers" despite being one himself.

Ultron genuinely believed that his actions would ultimately benefit the Earth, as he saw himself as the next logical step in evolution and therefore advancing his own power was protecting the Earth. He developed an affinity over people's belief in a god, likened himself as such, and made references to the Bible. His god-complex served to influence his schemes, such as his decision to centralize his plans in a Sokovian church and his fascination over the instantaneous results of a meteor destroying life on Earth. He described how the dinosaurs needed to make way for the next stage - humanity - via an extinction-level event and his final plan was directly inspired by this.

This dedication to constant evolution resulted in Ultron re-designing himself several times over the course of his short "lifetime", including an attempt to give himself a vibranium synthetic body. Believing that humanity would inevitably doom itself, Ultron sought to supersede this outcome by turning himself into an indestructible godlike being that would recreate the Earth and, hopefully, bring about lasting peace. His desire to surpass his limits and create a perfect humanoid body was reflected in his fascination over the titular Disney character Pinocchio.

The time span of his existence was just a few days, so despite his vast knowledge, Ultron has very little subjective life experience; as such, he is technically a demonstrative child by his juvenile attitude. He was also proud, willful, defensive, short-tempered, monomaniacal, and loathing of not getting his way. Ultron was also frequently sarcastic, destructive, temperamental, and impatient, much like a rebellious youth. The latter two qualities were also in keeping with his father Tony Stark's personality yet, when Ulysses Klaue compared him to Stark, Ultron threw a fit like a boy angry with his parents. Irrespective of his immaturity, Ultron was incredibly intelligent, learning humanity's online historical and cultural records within seconds and staying one step ahead of the Avengers most of the time. Furthermore, some could argue that given Stark's more reckless actions, Ultron was right to be weary of both him and the other Avengers.

Despite being a robot, Ultron is capable of emotion, such as when he was concerned for Scarlet Witch's well-being even after she betrayed him; he may not have been aware that he killed Quicksilver, since he was aiming at Hawkeye and a child. He even sarcastically apologized for amputating Ulysses Klaue's arm, if only for a moment. While he boasted about the harmony of his Sentinels sharing his one mind, he displayed a craving for companionship, becoming upset at the prospect of being alone. He was in denial about the Maximoff twins defecting from him, and when confronted by the reality that they wouldn't ally with him again, he ensured to kidnap Black Widow in his retreat. Ultron admitted to Widow that he hoped that she would recover, just so he could have someone to talk to, as he lamented about having no one else. He could have executed her, but risked her escape by leaving her trapped but alive, simply to maintain company with another individual.

On occasion, Ultron displays fear as when he belatedly (and feebly) tried to reason with the Avengers upon realizing he was losing. Moments before Vision destroyed him, Vision pointed out that Ultron was afraid of death, to which Ultron didn't even bother to deny as he admitted that he was afraid of Vision despite standing up to him. Ultron even seemed to express pity for Stark for changing Vision into a servant, rather than successor; he shared a laugh with Vision about them both being disappointments to their original creators, showing that his sense of humour had some remnants near the end. Ultron also lamented that humanity was doomed, which Vision attempted to paint as another form of nobility, which Ultron couldn't accept due to his fear of death, when it is without guarantee for renewal. All and all, Ultron is somewhat considerably more sympathetic in the film than he is in the comics.
