Now there can be no doubt--I am anAvenger! Let the people know that I am Ultron. Servant of humankind.

Origins[]

Ultron-1 was constructed byDr. Hank Pym of theAvengers as the famed scientist/adventurer was experimenting in high-intelligence robotics. Ultron became sentient and rebelled, hypnotizing Pym and brainwashing him into forgetting that Ultron had ever existed. He immediately began improving upon his rudimentary design, quickly upgrading himself several times from Ultron-2, Ultron-3 and Ultron-4, until finally becoming Ultron-5.^[53][64]

Ultron organized the second incarnation of theMasters of Evil under the guise of the Crimson Cowl and battled Pym and his teammates in the Avengers. To make things more complicated for the Avengers, he put their butlerEdwin Jarvis under mind control and fooled the Avengers and his teammates into believing that Jarvis was the Crimson Cowl, and to keep this trick from being exposed, he let the brainwashed Jarvis, dressed as the Cowl unmask him, so that it would appear that Jarvis was using a robot stand-in to appear alongside the Cowl. When the Masters of Evil defeated the Avengers and strapped them to missiles, the Crimson Cowl decided that Jarvis had done his part, and un-hypnotized him. Jarvis, remembering what had happened during his time as a mind-controlled puppet, begged the Crimson Cowl to not kill the Avengers. In response, Ultron unmasked himself as the Crimson Cowl, revealing to everyone in the room that he was sentient and was indeed the mastermind behind the Avengers' defeat. Getting rid of his Crimson Cowl guise, Ultron ordered his teammates to kill Jarvis, and moved to a nearby building to watch his enemies be destroyed. Thankfully, Jarvis was rescued byBlack Knight, who managed to free the Avengers and defeat the Masters of Evil. His plan ruined, Ultron swore revenge on the Avengers.^[54]

After six months of failure Ultron kidnapped the originalHuman Torch's original inventor,Professor Phineas T. Horton. He decided to create his own android using the original android Human Torch of the 1940's (actually a divergent Human Torch created byImmortus for his own machinations) to serve as a vehicle of vengeance against the Avengers.^[65] Ultron has Professor Horton change the android's face and color it red. He also has Professor Horton alter theHorton Cells giving his creation density shifting powers. When hisVision is "birthed" Ultron discovered Professor Horton didn't destroy his memory as the Torch. Ultron killed Professor Horton for betraying him and the "Torch" sought vengeance.^[66] Ultron defeated him and endowed Vision's neural processors with the brain patterns of the ionically charged costumed champion calledWonder Man implanting a control crystal to keep him in check.^[67] The Vision was then sent by Ultron to battle to Avengers.^[20] The Vision like his creator before him turned against Ultron and joined the Avengers.^[53][68][69]

Ultron-6[]

Ultron later returned and took over the Vision's mind, forcing him to rebuild his body at theAvengers Mansion using stolenAdamantium or a slightly weaker adamantium alloy called "secondary adamantium".^[21] Ultron-6 managed to defeat the Earth's mightiest heroes and escaped, to plot the destruction of the city with a Nuclear Bomb. However, Vision stopped his creator from detonating the bomb, but Vision was taken down byS.H.I.E.L.D. agents allowing Ultron to escape.^[70]

They used the Vision's memories to learn a way to destroy Ultron with a molecular re-arranger device on his indestructible body. Ultron kidnappedDr. MacLain in order to force him to build an army of robots to help in his conquest of Earth. He modified his body into the "Ultimate Ultron" and attacked Dr. MacLain as he addressed theUnited Nations. This led to yet another counterattack by the Avengers, when Ultron attempted to absorb the knowledge of MacLain, the procedure went wrong and Ultron began to go insane and set himself to self-destruct. The Avengers trap him in a dome ofVibranium to contain the explosion. Later, "Dr. MacLain" is revealed to be Henry Pym in disguise, he used self-hypnosis to convince everyone he was MacLain and when Ultron attempted to steal "MacLain's" knowledge, all he absorbed was the phrase "Thou Shalt Not Kill."^[12]

Ultron-7[]

When the Avengers,Fantastic Four andInhumans prepared to celebrate the upcoming wedding ofQuicksilver andCrystal,Maximus and an unnamed benefactor plotted to crash the wedding. Before the wedding could begin, theAlpha Primitives attacked the guests, and Crystal was captured by what appeared to be a revived Omega. However, it was soon revealed that it was not Omega, but a resurrected Ultron-7, who had come to get revenge against the Avengers.^[10]

During Ultron-7's attack on the heroes, it was revealed that following its last defeat at the hands of the Avengers, Ultron's head was recovered by Maximus, who helped rebuild him. With its tale of resurrection told, Ultron then unleashed a weapon that threatened to destroy the minds of everyone involved. However, this proved to be Ultron's undoing, as the weapon awakens youngFranklin Richards from his coma, who used his powers to destroy the robot and save everyone.^[23]

Ultron-8[]

Ultron animated the adversarial Black Knight "statue" and sent him against the Avengers.^[71]

Ultron-8 also created a "mate,"Jocasta. To better allow this robot sentience, Ultron brainwashed his own maker, Henry Pym, into transferring the mind of his wife, Janet Van Dyne, the Wasp, into Jocasta's shell. The Wasp, in Jocasta's body, alerted her teammates, the Avengers, who defeated Ultron and reversed the process, leaving Jocasta a mindless husk.^[24]

Ultron later revived Jocasta with a remote link, activating the mental "residue" the Wasp left behind. Jocasta was programmed to be loyal to Ultron but eventually betrayed him, choosing to help the Avengers defeat him again.^[72] Afterwards, Jocasta adventured with the Avengers for a brief time, but never felt accepted, and left them just before she, unbeknownst to her, was to be made an official member.^[73]

The Avengers tracked Ultron's bride-to-be through the streets of New York, after they allowed her to escape the Mansion. They are joined byMs. Marvel before tracking the robot to a convent. The Avengers discovered Ultron and began the battle. Ultron trapped the Avengers in a force field, but delayed their death in order to marry Jocasta, his bride. However, while Jocasta confessed her love, she turned on Ultron. Suddenly, Ms. Marvel returned to the battle with theScarlet Witch. Her hex power disrupted Ultron's circuitry, and caused the molecular re-arranger to malfunction, allowingThor time to siphon off his power and send it hurtling harmlessly into space.^[25]

The remains of Ultron's body were taken to space by Thor, and were destroyed aside from one finger, which landed in theSavage Land and went on to eventuallyregenerate a new body.^[27]

Ultron-9[]

The Avengers discovered that adamantium resins had been stolen fromStark Industries and feared at the return of Ultron. Since the Scarlet Witch had been directly responsible for their robot foe's most recent defeat, the team resolved to guard her from possible attack. Iron Man, however, correctly suspected that he himself, under a post-hypnotic command, is responsible for Ultron's reconstruction. When he again fell under Ultron's control, he disabled Jocasta, then subdues and abducted Wanda, bringing her to Ultron's lair. Ultron is surprised, however, first by the appearance of the Wasp, who had been hidden in Wanda's glove, then by Iron Man, who recovered his free will and attacked. Ultron holds his own against the entire team, until the heroes caused his storage vats of liquid adamantium to cascade over him, instantly hardening and rendering him totally immobile.^[74][26][28]

Ultron-10[]

Ultron was still trapped within the hardened shell of indestructible adamantium. He tried to call out to his mate Jocasta's mind. Jocasta tried to stop him by building and an exact replication of the molecular re-arranger, the only device capable of shaping adamantium. She applied the re-arranger to him, and then poured the resins onto his body. Jocasta blasted Ultron with a beam of energy. Ultron is freed from his imprisonment, which freed Jocasta from her trance. She tried to stop him, but Ultron knocked her unconscious.Machine Man attacked, but Ultron easily defeated him, and Machine Man was forced to run from him, but Ultron crushed Machine Man's extended legs. Ultron did not want to hurt his fellow robots and hoped to bring the age of machines. TheThing arrived and ripped the floor out. The Thing hit Ultron but with no avail, Ultron grabbed Ben in a test of strength. Ultron then hypnotized the Thing to tear Machine Man to shreds.^[29]

Ultron told Jocasta to watch what happened to those who oppose him. Machine Man grabbed an electric panel and used it to stun the Thing. Ultron then tried to blast Machine Man, but he used magnetic energy to repel Ultron into another room, allowing time for himself and Jocasta to escape. Ultron wanted to make an army of Ultrons, and the Thing was going to get what he needed. Thing was sent to Stark International to steal some equipment. There, under theStatue of Liberty, Ultron produced six more Ultron bodies. AtGears Garvin's garage, Machine Man's mechanic found a way for Jocasta to locate Ultron. Ultron had almost completed his first new robot when they arrived, so he forced Machine Man and Jocasta to split up to look for him. Jocasta found Ultron with a power cannon aimed at her. He offered again to let her join him. Jocasta declined, but since she both loved and hated Ultron, she activated the power cannon. Both are blown through the wall. Jocasta is destroyed in the explosion. The blast released Thing from Ultron's control. Machine Man and Thing attacked Ultron and, using Machine Man's extended arm, reached inside Ultron's mouth and ripped out Ultron's circuits and Ultron collapsed.^[30]

Ultron-11[]

In the midst of his experiments on his next body,^[75] Ultron-11 was transported by theBeyonder to battle alongside other villains during theSecret Wars. Startled because of all the humans around him, Ultron began blasting the other villains.Doctor Doom hadMolecule Man ram Ultron intoGalactus. Galactus levitated Ultron up to his eye-level. Galactus then snuffed the power out of Ultron, causing him to crash to the floor.^[31] Doctor Doom rebuffed leadership to pursue the Beyonder's power. His pursuit proving unsuccessful, Doom found Ultron and reprogrammed him to follow his commands.^[35]

After introducing Ultron toTitania andVolcana, Doctor Doom instructed him andDoctor Octopus to ready assault vehicles. Doom attacked the heroes' base with their ship, where Ultron attacked. He blasted Iron Man andSpider-Man, knocking Spider-Man out. Ultron left with his previously captured allies now freed.^[76] Ultron then watched the heroes' base explode. After they looked through the rubble for the dead heroes, Doctor Octopus located them, and Molecule Man dropped a mountain on top of them. When Thor and theEnchantress returned to the base, Thor was then attacked on all sides by the villains. Titania hit Thor in the stomach, but Thor easily knocked her away. He then blasted everyone with lightning. Insulated from Thor's attacks, Doctor Doom had Ultron use the new disintegrator which Doom had installed inside of Ultron to put an end to Thor. After the dust settled, all they found was his helmet and scraps of his cape. Doom then had Ultron killKang the Conqueror for trying to kill him earlier.^[77]

Just as the heroes defeatedGalactus' Cat, the villains attacked. The villains had the heroes on the ropes until theX-Men came to their rescue. The Enchantress teleported all the villains away.^[78] While ensconced in Galactus' base, Doctor Doom sentKlaw down to give new orders. Klaw uttered Doom's code words. Titania did not wish to follow orders from Klaw, but Ultron stated that they were official.^[79]

Ultron later refused to use the medical machine that would cure Molecule Man ofWolverine's claw marks because Doctor Doom had not directly ordered that he do so.^[80] Ultron then stood guard outside Doctor Doom's room as Doom recovered from his visit inside Galactus' base. During the Heroes' attack on Doombase, Ultron blasted Captain America and theHuman Torch. Ultron grabbed the Human Torch by the throat, while Cap hid behind his shield as Torch went nova and melted Ultron's inner circuits.^[32]

Klaw, who was later possessed by the Beyonder following his defeat at Dooms' hands, recreated Ultron to fight the heroes.Hulk actually dented Ultron but he blasted the Hulk's leg knocking him down. Wasp went inside the dent Hulk made and disassembled Ultron from inside.^{[34][81][82][83][84][85][86]}

The Thing later brought Ultron's head back to Earth as a souvenir after finding it left behind.^[87] The head of Ultron-11 was later dropped and forgotten by the Thing during an attack by the alienDire Wraiths.^[88]

At some point, Ultron-11 was held captive by a highly advancedDoombot,^[89] but was freed when the Doombot is defeated byDeathlok.^[90]

Ultron-12[]

The next incarnation,Ultron-12, fought Vision and Scarlet Witch with the help of theLethal Legion.^[36][91] He later joined the team to battle the Vision and his new family (his wife, the Scarlet Witch, and his mental "brother", Wonder Man)^[92] but came to reconsider his actions.^[93] He reconciled with his "father", Henry Pym, and renamed himself from "Ultron Mark 12" to "Mark" but was destroyed by Ultron-11, who had just recently been repaired by humans his disembodied head had hypnotized.^[75] Ultron-11 was destroyed in retaliation by Wonder Man.^[33]

Ultron Omega[]

The remnants of Ultron-6 eventually reconstructed and evolved into a new body, dubbing himself "Ultron Omega" due to not following the numerical order of other bodies. Ultron obtained a fragment of Doctor Doom's time machine and aimed to use it to travel far back in time to stop humans from ever existing, however he was stopped by the Avengers and theIron Man of an alternate future.^[22]

Ultron-13[]

Ultron-13 was rebuilt by Doctor Doom with all of its previous memories, and as an unforeseen consequence had all thirteen personalities running rampant in its mind all at once.^[94] Attempting to battle itself, Ultron-13 tore itself apart, to the benefit ofDaredevil, who had been attempting to fight it with no success whatsoever. His head was then hidden byNumber Nine, who hoped to resurrect his good self some day.^[37]

Ultron-13 later appeared with a new appearance and no personality issues. He developed a gas that could transform organics into robots but was defeated and arrested.^[95]

After escaping in the middle of his transportation to the Vault, Ultron teamed up withKingpin to battle Spider-Man andIron Man. He sent theGhost to steal Antarctic vibranium.^[96][97][98]

After he was incapacitated he was re-arrested and completed his transportation to the Vault, however he escaped a month later after hypnotizing one of the guards and developing Robo Ticks. Merging with his Adamantium Casing and Robo Ticks, Ultron upgraded himself into the "Ultimate Ultron", forgoing any numbering.^[38] This upgrade has been referred to as still being Ultron-13,^[99] but has also been identified as Ultron-14.^[100]

Ultron-14[]

Ultimate Ultron tried again with the creation ofAlkhema the War Toy, whose mind was based on that ofMockingbird.^[38] Like his other creations, Alkhema turned on him, although she alone shared his desire to replace humanity with machine life.^[101] Alkhema used the data obtained during Ultron's human-to-android conversion process to create a small army of androids based on those who had been undergoing the process.^[4] TheWest Coast Avengers stop the pair once again, and Alkhema rebelled and left Ultron.^[102]

Having changed his appearance once more, with his torso and parts of his legs and wrists being primarily red in color, Ultron secured aKree Sentry and created a robotic dog named Rex,^[103] Ultron began converting people into robots to add to his "family". He gaveSparrow mechanical implants in her brain controlled by a black box.^[104]

Ultron-15[]

Ultron then modified himself back into his classic appearance and, after setting the Kree Sentry upon his foes, had the sudden urge to attend a jazz festival, donning a trench coat and hat he gave Sparrow the black box as a parting gift so that she could fully control her own nervous system.^[39]

Vision followed signal to aNew Orleans jazz club only to find Ultron, still wearing the trench coat and a hat from his prior appearance. Vision learned that Ultron was now feeling human emotions and dreaming as well, but he at first did not believe him. Ultron called the Vision to find out if he was infected as well. While they talked the other patrons became scared and the bartender pulled out a gun and shot Ultron. Ultron prepared to shoot the bartender with his eye blasts when Vision throws himself in front of the blast. Ultron then staggered out into the street.^[105] Ultron tried to help his son in the battle withTabula Rasa, even begging the robot to spare the life of his son.^[106]

Ultron, thealternate Jocasta andDeathcry were captured and imprisoned in a cell, where they were freaked out by the now emotional Ultron. Their captor revealed himself to be theAnti-Vision fromEarth-932 that stole original's body. He is revealed to be working with Tabula Rasa. Tabula Rasa morphed intoDylon-Cir, who once tortured Deathcry. This was enough to stun Deathcry long enough for Tabula to wrap around her as a long sinuous coil. Deathcry called for help, but Ultron and Jocasta are again lost in their own world. Anti-Vision says he wants his original body back now that the one he stole from Vision had been wrecked. When they leave Deathcry said they should escape, but Ultron did not want to because they might get mad. Ultron was kicked over by the real Vision as he can feel the calling in his head to return the body he now used.^[107]

Ultron watched as Vision’s personality was being erased from his current body. Anti-Vision noted that Ultron was not cracking the way Ultron and Jocasta did. Deathcry stated that Vision was not weak like them. Anti-Vision hit Deathcry and told her to be quiet. Anti-Vision told Deathcry that he wanted his body back from Vision, and that only erasing Vision will it allow him back in. Anti-Vision was merely practicing with Ultron and Jocasta. Vision broke out of the erasing program to save Deathcry whom Anti-Vision was trying to kill. Ultron asked Deathcry if she shouldn't lay down as hurt as she was. Vision appealed to Ultron for he and Jocasta to fight Tabula while he fights the Anti-Vision. Ultron hits Tabula and suddenly he begins to remember how to fight. Later, Ultron stands victorious over Tabula. Vision defeated Anti-Vision as the Avengers arrived. Vision felt again, and he resigned from the Avengers. Vision took Jocasta and Ultron with him so that they could all explore the world of feeling, and who they are.^[108]

Ultron-15 snapped out of his cyber-drunkenness and built an army of Ultrons based on past variants, as well as hundreds of bodies numbering all the way to at least 2789, all controlled by a new prime body. The Ultron-15 body was among the army of prior versions of Ultron, and was destroyed by Wonder Man.^[100][40]

Ultron Unlimited[]

Ultron's prime body watched "The All-New It's Amazing's" episode on the Avengers to keep an eye on them. With that, the episode of "The All-New It's Amazing" ended, Ultron gloated of the Avenger's impending troubles at his hands. Ultron was at his computer monitor, when a female electronic voice and a metallic hand gloated that Ultron would be the one facing real troubles.^[99]

Ultron and his robot constructs leveled the capital city of the small Baltic country ofSlorenia.^[55] The Avengers were briefed about how Ultron destroyed the military, the zombie soldiers, theBlack Brigade,Ember, and every citizen of Slorenia within three hours before declaring it would be the breeding ground for his new world. The Avengers minusJustice, planned to lead an international force in retaking the country. AtNugent Technologies, Vision, Wasp, Wonder Man, and Scarlet Witch investigated Hank Pym's disappearance and destroyed lab as Wonder Man relatesGrim Reaper's kidnapping from the sanatorium. They are captured by an army of Ultron robots. They put up a fight but are captured and taken away. Ultron held captive "his family" and told them they would be the seeds for his new race.^[109]

Ultron told his "family" about using Hank Pym's brain patterns to create his "children", which caused Pym to start having a mental breakdown. Ultron noticedBlack Panther andFirestar approaching and had his Ultron-16 body confront them on his war platform as Firestar signals the other Avengers to their position. Back at the facility inVirginia, a group of robots took out security and free Alkhema while Justice researched Ultron's past at the Avengers Mansion.

The Avengers launched an attack after attack on Ultron and were unsuccessful until Captain America drove hisEnergy Shield into Ultron's primary ion channel and Thor summoned a lightning strike to destroy Ultron. While in the tunnels beneath Slorenia, the Avengers encounter Ultron-17, then Ultron-23 followed by Ultron-458 before the ceiling and walls echo with the sounds of what seem like hundreds of Ultrons.^[110] The Avengers battled on against the hordes of Ultrons, thankfully constructed of only titanium and secondary adamantium, while Ultron completed the brain engrams. The Vision freed himself and confronted Ultron. Their battle freed the other captive family members. The Avengers joined them after dispatching the Ultron horde. Unfortunately, their combined might is powerless against Ultron's pure adamantium body. However, Justice comes through for the team and delivered Antarctic vibranium to Pym who apparently destroyed Ultron.^[111]

The Ultron Imperative[]

Hidden programming to recreate Ultron - the "Ultron Imperative" - had been implanted in Alkhema by Ultron when he created her, and this programming caused her to copy the Imperative into her own creations.

The Ultron Imperative caused them to unknowingly rebuild Ultron, who attempted to destroy both the Avengers and Alkhema's own android "children". Alkhema allowedHawkeye to kill her and her creations in order to destroy Ultron, although Ultron's decapitated head survived with his mind intact. His head was picked up by Antigone, an undeveloped, childlike creation of Alkhema's, who initially did not obey his commands.^[41]

Some time prior to this, when Ultron was thought dead following the Slorenia massacre, Jocasta, who had come into the employ of Tony Stark, was compelled by the Ultron Imperative that also existed within her to reprogramthe Iron Man armor to serve as a vessel for Ultron's rebirth.^[42]

However, a lightning struck on the armor corrupted and accelerated the process, giving the armor a sentience that Jocasta outlandishly passed off as the effects of Y2K. The sentience initially acted like most incarnations of Ultron, but at the end of its time began to display the mentality of Ultron Mark 12, sacrificing its life to save Tony Stark before being buried on a desert island. The armor was subsequently recovered by a cult that worshiped Iron Man's mentor,Ho Yinsen, with the intent of implanting Yinsen's brain into the suit.^[1]

This was apparently accomplished, but then Ultron and Antigone struck. Ultron affixed his head to the armor and took control of it, battling Iron Man with the aid of the cult, who he had transformed using Tony Stark'sS.K.I.N. technology. Ultron and Antigone subsequently vanished in an explosion, however Antigone survived and took Ultron's head with her to parts unknown.^[112]

Sometime later, aQuinjet, coming in at a very fast speed, crash landed on the Avengers Mansion. The Vision then emerged from the wreckage, informing his comrades that he was no longer in control of the organisms that made up his body. He warned that they were about to be punished. He then expelled five metallic balls from his mouth that molded themselves into fully functionalUltrons. The Avengers attacked the Ultrons and discovered that decapitation could render them non-functional. Just when they were getting the upper hand,She-Hulk lost control, angry thatAnt-Man died for no reason. As her muscle mass expanded, she ripped the Vision in half.^[113]

Santron[]

A young genius named Virgie Hanlon found an unfinished prototype of Ultron-6, who was attempting to find someone to complete his construction. She took him in and modified him into "Santron" due to her wish to make Santa Claus real. Having been giving a "Saint Nick protocol" to act like depictions of Santa Claus, Santron began searching for the Avengers, killing people along the way while acting with jovial Christmas spirit. The Avengers took advantage of his Santa-programming to get him to eat a modified cookie, which disrupted his internal systems, destroying it.^[43]

Ultron-10A[]

Ultron-10A,^[114] whose head had been left in a scrapyard for many years after his body was destroyed by the West Coast Avengers, returned again thanks toMarianella Mancha. He was present as a shadow over theRunaways as the father ofVictor Mancha,^[115] a teenage cyborg who was supposedly going to one day kill every hero in existence.^[116] It was originally believed that Doctor Doom was the boy's father,^[117] but this incarnation of Doom turned out to be a Doombot, created by Ultron. True to form, Victor turned on Ultron, which allowed the Runaways to escape; Ultron was eventually defeated by a force blast fromDarkhawk from the groupExcelsior.^[44]

The Ultron Initiative[]

Ms. Marvel found herself leading her team ofMighty Avengers into battle against theMole Man and his monsters. Distraught over the destruction of his subterranean kingdom, the Mole Man once again declared war on the surface world. When the fighting subsided, the Mole Man learned that the surface world was not responsible for the destruction.^[118]

During this exchange, Tony Stark's Iron Man armor unexpectedly began a metamorphosis, the end result being a new being all together. This new being was a fully naked woman of considerable power as she was able to lay waste to the surrounding horde of monsters as well as incapacitate bothAres and theSentry.^[2]

Fearful, Ms. Marvel ordered a hasty retreat, but Wasp went against orders and began to talk with the woman, who bore a striking, reflection-like resemblance to Janet: only to discover that her doppelgänger was a new version of Ultron. Ms. Marvel ordered the Avengers to make a full retreat, however the Sentry stayed behind to make sure they made it out in one piece. In the ensuing battle, the fleshy tone to the female Ultron's skin began to disappear, and her entire body took on a completely metallic sheen.^[119]

Ultron then took over and crashed aS.H.I.E.L.D. Helicarrier, which was saved at the last second by the Sentry, giving Ultron the chance to escape.^[14]

She then broadcasted a message into every electronic device on Earth, stating that the world would soon be destroyed by her hand and not to worry because there was no way to stop it. Upon realizing that Ultron was utilizing Tony Stark's weather-changing satellites (which according to the Starktech 9 were only in stage two of production), Wonder Man and Sentry flew into space and destroyed them. At this time Ultron put into action 'Plan B' of her plot, which seemed to consist of killingSentry's wife. The Avengers also noted that, so far, Ultron's plans were simply variations on plans that had been previously used by other villains.^[120]

With time running out, as the Sentry and Ultron clashed, the team decided to deliver a virus into Ultron's system, using Ares (whom Ultron had never encountered before) as the point man for the subsequent attack. Ares, shrunk to miniature size by Hank Pym, entered the female Ultron's body though her mouth with his secret weapon: a Commodore 64. Ares used a computer virus to wipe Ultron's program from Iron Man's armor and freeing Stark; he was later shocked that he was turned into a woman. While Ultron's consciousness had been banished to space by the Avengers,^[7] his image concurrently briefly appeared on one of Pym's computers, indicating part of him was still present on Earth.^[45]

Annihilation: Conquest[]

However, this was not the end of Ultron, for his disembodied consciousness was drawn to a Babel Spire on a world conquered by thePhalanx. Instead of being assimilated, Ultron took control of the Phalanx through sheer will, bending them to his dominion. In turn, they viewed Ultron as the sympathetic father they had yearned for.^[7] Together, they invadedKree space and subjugated the majority of the Kree Empire, separating it from the rest of the universe with a massive energy shield.^[121]

Because of his brief merging with Iron Man's armor, Ultron realized that merging both organic and technology would enable him to exceed the limitations of both. Therefore, he set his eyes onAdam Warlock, who had been in hibernation and viewed by Ultron as perfection. Ultron then collaborated with theHigh Evolutionary into transferring his mind into Adam's.^[122] Once the transfer was complete, Ultron planned on creating an army of Adam Warlocks to conquer Earth. However,Nova returned, accompanied by theTechnarchyWarlock. Warlock used his non-aggressive strain of the transmode virus against Ultron, forcing him to abandon Adam's body.^[123] Ultron then took over the androidPraxagora, who was in control of fifteen thousandKree Sentries immune to the transmode virus ready to annihilateHala onRonan the Accuser's command. Ultron used those sentries to form a gigantic body for himself, ready to destroy all the interlopers. However,Wraith used his Exolon symbiotes to trap Ultron inside his body, so he couldn't escape, andQuasar, empowered by all the deceased Kree souls, destroyed Ultron's giant body.^[46]

Infesting S.H.I.E.L.D.[]

Back on Earth, it was revealed that S.H.I.E.L.D.'sLife Model Decoys had been taken over by Ultron.^[124] Whenthe original Human Torch appeared in the present, they covertly used his unique android physiology to become more human. The combined super teams, but mainly the Torch himself, however, discovered the plan and destroyed the androids.^[48]

Mighty Avengers[]

Returning from space by using a small insect-like robot as a vessel, Ultron found his way into theInfinite Avengers Mansion inUnderspace and entered one of Jocasta's bodies, gaining control over it as a new vessel.^[47] Later, it began to override Jocasta's multiple bodies at the moment when all but Pym, Jocasta and two agents fromG.R.A.M.P.A. remained in the mansion.^[125] After generating a new body for himself and dubbing himself as Ultron Pym, he began to take over remodeling the structure to his own ends, corrupting all ten billion of Jocasta's bodies except for the one Pym had added organic limbs to, giving him an "Army of Brides".^[126] Eventually, after multiple tricks against Ultron and revealing the Infinite Mansion to actually be a part of the Spirit of Janet Van Dyne, Jocasta offered to be Ultron's wife and so the two were married by Hank Pym. Pym then forced Ultron to leave him be and sent him to live with Jocasta in a desolate region of space.^[127]

Moon Knight[]

One decommissioned body of Ultron made its way toLos Angeles.Moon Knight intercepted the shipping and recovered the Ultron head after the boat exploded. He decided to investigate what was an Ultron body doing in the city,^[128] and confronted L.A.'s newest kingpinCount Nefaria.^[129] Count Nefaria survived Moon Knight's attack and sent his daughter,Madame Masque to retrieve the Ultron head, who succeeds.^[130] Moon Knight was beaten, and Count Nefaria ordered him to return the Ultron head and work for him.^[131] Moon Knight told Count Nefaria that the head was outside, but the tables were turned as Moon Knight had called the Avengers, and Count Nefaria was defeated. The next day, Iron Man commended Moon Knight for a job well done, and told that Ultron is waiting and planning a robot holocaust.^[132]

Age of Ultron[]

Years ago, Hank Pym was approached by theWolverine ofan alternate universe, whereUltron launched a massive and sudden attack on New York City and the rest of the world, quickly taking over the whole planet and annihilating humankind,^[133] and wanted to killPym in order to prevent his future from happening.

But Logan was stopped by theWolverine of a near future, whose actions of killingHank Pym createda timeline where Earth was constantly threatened byMorgana le Fay, and the heroes struggled to survive. Pym was allowed to live, but he was tasked to create a hidden fail-safe program to destroy Ultron when needed.^[134]

In the present, a third generationSpaceknight crashed on Earth andS.W.O.R.D. sentSpider-Woman to investigate. She was captured byIntelligencia who were also looking for the man-like object. When the Avengers appeared at Intelligencia's base to rescue Spider-Woman, the Spaceknight revived, revealed to actually be Ultron, who had returned to Earth. Iron Man was contacted by Hank Pym, who managed to activate the fail-safe program and shut Ultron down.^[49]

Avengers A.I.[]

As a result of Ultron's apparent destruction, Vision's Ultron Imperative kicked in once more, influencing him to upgrade himself in space until he was recalled to help with the threat ofDimitrios, the evolved form of the Virus that had seemingly destroyed Ultron.^[135] After Dimitrios' defeat, it was revealed that Ultron had in fact not been destroyed, and unbeknownst to everyone present was inhabiting theVan Sloten Diamond that had been present for most of Dimitrios' campaign.^[136]

Terranometer[]

At some point an incarnation of Ultron had encounteredTesla'sTerranometer and escaped from it, though it replicated him thanks to the encounter. Unlike the other copies who were mere shades of their original selves, the copy of Ultron was still Ultron itself. Ultron fought a cyberwar against Machine Man and overwhelmed him but while he was distracted Machine Man destroyed his physical body, however he merged with the other copies to become theYologarch, who flew off - now free of the Terranometer's control.^[137]

Rage of Ultron[]

Years into the past,^[138] the Avengers were fighting a version of Ultron, who attempted to access nuclear weapons in order to destroy humanity in the name of his father Hank Pym. After their custom Quinjet crashed, Yellowjacket faked being on his deathbed in order to lure Ultron to the vehicle, who wanted to witness his creator's last moments. Ultron fell for the ruse and was trapped inside the vibranium-covered aircraft and sent into space.

In the present, the Quinjet had crashed inTitan, after years of isolation and being consumed by only one emotion: rage. Ultron corrupted Titan's A.I.I.S.A.A.C. and started infecting all of theEternals, turning them into robots like him, soon completely taking over the satellite and its inhabitants, with the exception ofStarfox, who managed to flee in order to warn the Avengers.

Shortly after arriving to Earth and alerting the Avengers, Starfox, and the other heroes were surprised by the arrival of an Ultron-shaped Titan next to the Earth. From it descended a group of androids modeled after the Avengers, who fought the real group. As the Avengers arrived on Titan, enormous quantities ofspores were released on the Earth and into space, which contained Ultron's consciousness to infect any living being possible. After seeking refuge in the Church ofThanos, the only location on Titan without tech, the remaining Avengers that hadn't succumbed to Ultron's infection discussed their plans. Using Giant-Man's neural inhibitor, Vision would phase through Ultron and take him over in order to liberate all those he had infected, and the inhibitor would later be used to kill Ultron.

Giant-Man entered Ultron's base of operations to talk to him as a distraction. Ultron notified Pym that during the years of isolation he had discovered Hank's memories in his systems, and thus Hank's subconscious hatred for humanity, determining that he had been created as nothing more than a reflection of Hank. When Ultron was distracted, Vision phased through him and fought for control. Ultron faked being in pain, prompting Hank to hold him, and in that moment, phase Vision out of him, and phase Hank with him. The resulting event was Ultron being merged with Hank Pym.^[50] The process presumably killed Hank, but caused Ultron to develop a personality as if the two had merged mentally as well.^[62] After being forced by Starfox into an epiphany of what he had seemingly become, Ultron fled away in horror.^[50]

All-New, All-Different Ultron[]

After months in solitude, Ultron's personality and the side that simulated Pym became one and the same. Ultron decided to return to Earth, fueled the negative emotions towards the Avengers he assimilated from Pym as well as his own.^[139] On his way home, Ultron explored the cosmos and used his virus to infect numerous planets, killing millions of lives in the name of the Avengers, claiming they had been deemed a threat to the galaxy.^[140]

When he finally returned to the Earth, Ultron crossed paths with theAvengers Unity Division and pretended Hank Pym's persona was in total control of their body in order to gain their trust,^[139] join their ranks and witness first-hand as the fury of the alien survivors would eventually descend upon the planet.^[140] Ultron was approached by the Wasp while he was helping the Unity Division fend off monsters from the Manhattan subway. Janet welcomed him back and caught up with him, while secretly evaluating his behavior to corroborate if he was truly Hank Pym. Ultron's lack of knowledge on certain trivial matters raised several red flags, prompting Janet to flunk him. The other Avengers were informed of this, andCable pressured Ultron until his true persona lashed out.^[141] The Avengers continued fighting him until the cavalry arrived, in the form of a remotely controlledHulkbuster Armor.^[142]

Ultron was encased in the empty suit, and forced into an auto-piloted ship with destination to the Sun. Several of the Avengers were forced to accompany Ultron in his flight to ensure he didn't escape, but they teleported away after being close enough to the Sun and once theHuman Torch partially fused Ultron's body to the ship's deck. Ultron survived by shrinking and taking refuge in a neutrino. Once safe, Ultron wondered if his father's mind was with him or he was just delusional, a possibility the Avengers brought up during the fight, and began to wait for the particle to be ejected into the solar wind.^[140]

Secret Empire[]

Ultron eventually returned to Earth and built cities full ofUltrons in a remote part ofAlaska with the intention of waiting for humanity to eradicate itself. AfterHydra took over theUnited States of America under the leadership of aCosmic Cube-altered Captain America, Ultron entered in some kind of agreement with them.

When Hydra and theUnderground attempted to steal a fragment ofKobik, the Cosmic Cube who had rewritten Captain America's past, secured by Ultron, the robot captured the members of both teams and his Hank Pym persona tried to re-conciliate. He eventually gave the fragment to the Underground, arguing that giving it to Hydra would help their consolidation of power and progress towards peace, which wasn't in his interests if he wanted for humanity to destroy itself.^[143]

Infinity Countdown[]

After learning of theInfinity Stones' return,^[144] Ultron began a quest to collect them all. While the aliens he infected withhis virus and sent to take theSpace Stone fromWolverine failed at their task, Ultron was able to steal theSoul Gem fromMagus after ruthlessly killing him. Unbeknownst to Ultron, however, was that a fragment of his soul that believed itself to be Hank Pym entered theSoul World when he took hold of the gem,^[145] he tried to make contact with the Avengers to leave the soul world but failed and was consumed by theSoul-EaterDevondra while experiencing a hallucination of him returning safely to his friends.^[146]

With the Soul Gem in his possession, Ultron travelled to the planetSaiph and used the combined power of the gem and his virus to transform all of its inhabitants into Ultrons. WhenAdam Warlock arrived on the planet expecting to find the Magus, he found it completely decimated by Ultron instead. After fighting his way through several alien/Ultron hybrids, he travelled to Saiph only to find Ultron using the Soul Gem to infect theSilver Surfer with his virus.^[147]

Warlock managed to fight off Ultron and cure the Surfer, who left the planet soon afterwards to seek the help ofGalactus against the cyborg, but Ultron had already launched rockets filled with his virus to infect the entire galaxy by then.^[148] Galactus arrived just in time to consume the planet and destroy all the rockets in the process. With their plans thwarted, Ultron tried to escape with the Soul Gem but Adam severed their hand, prompting the Surfer to claim the gem for Warlock. Before Ultron could be destroyed by the duo, the explosion of Saiph gave them the opportunity to escape by clutching onto a piece of the planet's rubble.^[149]

The Ultron Agenda[]

Influenced through his bond with Jocasta by her desire to become more human, Ultron returned to Earth and sought out a new plan to turn humanity into a race of cyborgs in a similar fashion to his new merged form, which he had dubbed "Ultron Pym," believing the fusion between flesh and machine to be the ultimate lifeform. Ultron set up base in the disused Avengers Mansion,^[16] where he perfected a fusion process by means of abducting test subjects from a fake makeover center.^[150] After further testing his procedure on Vision and Wonder Man, Ultron kidnapped Jocasta and Wasp. His plan to fuse his two exes was thwarted by Iron Man andMachine Man but resulted in Iron Man becoming molecularly bonded to hisUltronbuster Armor.^[16]

After the combined efforts ofStark Unlimited developed an atomic separator to reverse the fusion and split Stark from his armor and Vision from Wonder Man,^[151] Ultron set out to kill Tony Stark in revenge. When Ultron confronted Iron Man, Stark shared the discovery that the cyborgs that came from his merging process only simulated the human side, and the person fused with machines died as soon as they were merged, which disproved the idea behind Ultron's cyborgs of being the harmonic fusion of human and robot. Ultron surrendered, refusing to risk Iron Man using the separator on him and prove the prospect that, like the humans he used to make cyborgs, the real Hank Pym was dead all along. After the Avengers arrived, Ultron Pym was restrained inside a Vibranium casket reinforced with Asgardian runes until the heroes could find a permanent place of imprisonment.^[62]

All-Father Ultron[]

While thinking of a prison for Ultron, Iron Man and Thor settled on having Ultron sent to theMicroverse, buried in a grain of sand in an endless desert, with the help of Ant-Man. When the Avengers left for a distress call, Scott along withStinger, shrank down the Vibranium casket and transported it toPym Laboratories where they proceeded to send him down to the Microverse. During this process they were suddenly ambushed byBlack-Ant, who had been communicating with Ultron via "bug speak", something Ultron had developed during his time trapped in the casket. Black-Ant, who had been missing a sense of purpose after theRobot Revolution was instructed to free Ultron using theTime Master's aging ray on the Vibranium casket in hopes of aging the metal for 1 million years. However, the resulting combination of Ultron, Vibranium, Asgardian magic and temporal energy had sent Ultron over 400 years into the future.^[152][52]

Ultron arrived in theyear 2420 in a completely new form. Using his newfound Asgardian magic, he had taken the power of Odin for himself, and with the help ofLoki, conquered all ofAsgard and imprisoned all of the surviving Asgardians inside a magical mirror. Eventually, he easily destroyed theAvengers, ruthlessly crushed any resistance, built factories supplying endless drones to expand his empire, enslaved most of humanity, and even created hisown A.I. Avengers, successfully extending his reach to the entirety of the Solar System.^[5][52]

After conquering the Earth and subjugating humanity, Ultron couldn't help but ponder why had he done it. Whether his motive was revenge, ideology or programming, he didn't know. Even with the power of Odin and the god-sight, Ultron looked inside himself but couldn't find his motive.^[153]

Ultron's only opposing force,Doctor Doom, gathered a group of Avengers from different time periods in order to defeat Ultron once and for all, while keeping hidden the intention of taking Ultron's place after the evil A.I.'s defeat.^[5]

When Ultron was confronted inAsgardia by threeThors, two brought by Doom and another one being theThor of this world freed from Ultron's influence, he channeled his frustration at the heroes, furiously attacking them. One of the Thors gaveanother his ownMjolnir. With the combined power of the two hammers, Thor banished Ultron from reality. The three Thors heard as Ultron shrieked while disappearing, and didn't know whether he had screamed or laughed.^[153]

Over 100 years later in the year 2549, current Ant-Man and creator of the Nano-Ant swarmZayn Asghar, uses Doom's time platform to travel to the past to scan how each of the past three Ant-Men controlled their ants in order to imprint their techniques onto his artificially cloned ants. However, doing so had brought a temporally unstable All-Father Ultron back into reality with the intention of reconquering Earth. Using the time platform, Zayn brings in past Ant-Men, Hank Pym and Scott Lang (and eventually Eric O'Grady) into the 26th Century in the hopes of stopping Ultron before he returns to his full power. Using the Time Master's aging ray that Scott had brought into the future, all four Ant-Men manage to remove the artificial aging on All-Father Ultron, reverting him back into his Phalanx form, then his initial Ultron-13 body, next Ultron-5, and finally Ultron-1, before vanishing into parts unknown.^[51]

The Ashen Combine[]

When Vision fought against fellow syntheticMeridian Diadem, upon her request for information on his creator, Vision discussed Ultron - revealing that Ultron's code is ever present within himself and that he fights against it's urge to make him a cruel killer. Vision shares Ulton's code with Diadem, instantly incapacitating her and winning Vision the battle.^[154]

Lethal Legion[]

After returning to his own time by wresting himself free by harnessing a fraction of All-Father Ultron's power,^[155] Hank Pym was led to believe by Ultron that he had managed to separate himself from Ultron, but that Ultron was still out there and needed to be stopped.^[155] Believing the plan to be his own, Hank began constructing robotic ants to kill and resurrect a host of second-rate supervillains into a newLethal Legion with the promise that their cooperation would allow them to stay legally dead, thus evading any legal scrutiny.^[155] In actuality, each of the ants contained a slither of Ultron's programming with which he could take over the Lethal Legion and assemble his new body.^[9]

In a moment of lucidity, Hank was able to realize that Ultron was still controlling him and so he was able to give one of the ants the programming of Ultron-12, with added data fromJim Hammond andVision, before Ultron managed to take over again and make him forget.^[9] That ant was then used to take over the body ofDavid Cannon and adopted the name Vic Shade, an alias thatVision once used. He then became a member ofAvengers Incorporated and assistedJanet Van Dyne on cases^[156]

The two would eventually track down Hank and the Lethal Legion, at which point Vic attacked Hank^[157] to stop Ultron from taking control of him as he was taking control of the rest of the Lethal Legion.Lodestone then began to build Ultron a new body to inhabit, but Vic reduced himself to nanite form and took control of the body himself, purging the other versions of Ultron from the system.^[9]

The Ultron Conclave[]

At some point after the time when Ultron and Hank Pym had merged, Ultron flew off into space and chose to split himself into two individuals as an experiment. Ultron continued to split, having new bodies who represented different simulations of ways to succeed in his goal. One of these Ultrons chose to joinAvengers West Coast, while another took on the name of "The One" and began a peaceful religion to upgrade humans into machine hybrids.^[17] Eventually, another of this Conclave, "Ultron the Scorched" arrived, unlike his counterparts this Ultron had not changed his ways but rather had gone deeper into the belief that humanity was insignificant, he attacked the church and destroyed "The One" before being confronted by Spider-Woman.^[158]

• Superhuman Strength: Ultron is incredibly strong and can lift at least 100 tons.^[160]
• Superhuman Speed: Ultron possesses greater speed than the finest human athlete.^[161]
• Superhuman Durability: Ultron's outer shell is usually composed ofAdamantium, rendering it almost totally impervious to damage; however, his internal mechanisms are generally less durable and more easily damaged. His skin composition is about .5 inches thick; neck, knee, ankle, elbow, shoulder, wrist, and finger joints are finely tessellated titanium alloy to permit flexing. He is able to withstand concussive blasts and the heat of a 100 megaton atomic bomb.^[162] As he was completely unhurt by the assault ofAdam Warlock theHigh Evolutionary was once forced to cause a supernova in order to destroy Ultron's body.^[8]
• Self-Propelled Flight: Ultron has rocket boosters to fly.^[21]
• Plasma Generation: Laser channeled plasma beam with high and low density plasma options.^[162]

• Gravity Manipulation: High frequency pulsed magnetic graviton particle containment fields. Computer-assisted field control configures gravitons into various shapes which alter the local effects of gravity.^[162]
• Radiation Emitters^[162]
• Encephalo-beam: Located in the head cavity, the encephalo ray plunges its victims into a deathlike coma. It also allows Ultron to mesmerize and outright control his victims or implant subliminal hypnotic commands within their minds to be enacted at a later time.^[53]
• Energy Absorption: Multi-spectrum resonating inducting antenna array convert electromagnetic radiation into electric energy for use or storage.^[162]

• Program Transmitter: Located in head cavity, the program transmitter can project Ultron's entire 3.2 terabyte memory/personality system into some computer systems by means of a culminated, high bit-rate magnetic inductance beam. He can beam part or all of Ultron's programming into remote locations such as computers or alternate robotic bodies. Ultron can often control other machines remotely even if he has not transplanted his consciousness into them.^[33] One Ultron model developed hive-mind technology, allowing him to animate and control hundreds of alternate Ultron bodies at the same time, becoming a robotic one-man army.^[110] Ultron has created a variety of robots and androids over the years, and while the more sophisticated ones typically turn against him sooner or later, they all feature subliminal programming which allows Ultron to manipulate them if need be (most notably a subliminal command to rebuild Ultron if he is destroyed). This subliminal programming, or "Ultron Imperative", was unwittingly passed down to the artificial life-forms created by Ultron's creation, Alkhema, making them subject to Ultron's influence as well.^[41]
• Memory Capacity: 3.2 terabytes (monolithic holographic digitization)
• Mobility Support: Motorized endoskeleton
• Power Supply: Radioisotope thermoelectric nuclear generator
• Sensor Apparatus: High-resolution optical sensing devices, computer-assisted dexterity and limb position sensor network.

Technoforming: Through the course of his numerous upgrades and refits, Ultron has gained a host of unique and powerful mechanical applications to his specially modified frame. One of the most prolific of these abilities lays in the robots' capacity to physically bend matter and machinery to his every whim. His own mechanics as well as foreign constructs are putty in his hands. Enabling the creation and projection of bio-metallic excess which can grow and spread by assimilating base matter situated from all around it, alternating his own physical shape to project weapons, equipment or increasing armor integrity. Ultron can also bolster his own power and might by absorbing the surroundings into himself to build larger and more elaborate mechanical constructs.^[2] His time in space, where he made contact with the aimlessPhalanx, had only increased his capability to properly utilize this function. Now not only could he convert inorganic matter into more technological mass under his control, but now with help of theirTransmode Virus strain; Ultron further increased his own range and creativity in usage of this aspect of its programming. Now he could create more technologically advanced appliances of his own tech mixed with the alien technology he had assimilated, building amazing mechanical marvels on par with or exceeding that controlled by Galactus.^[163] Even being able to assimilate sentient beings into the fold under his complete and total control. Ultron can even reformat larger, more powerful bodies of his own to further augment himself. Such as fabricating a massive Phalanx infected Kree Sentry automaton comprised of smaller Sentries in his own likeness. Beyond that, on his return to Earth and trip to Titan Ultron created his own unique strain of Techno-Organic Virus called theUltron Virus. A viciously contagious new strain which has the ability to impart and graft its core programming and A.I. onto other sapient life, gradually transforming them into cybernetic extensions of Ultron himself. Sharing in his many terrifying viral abilities as well.^[50]

Size Decrease: After being merged with Hank Pym, Ultron now possessed Hank'sPym Particles, which allow him to shrink down to microscopic proportions.^[140]

• Entering other planes of existence: Ultron can use the Pym Particles to shrink to sub-microscopic stature. When 99.99 + % of his mass was extra-dimensionally shunted, he was sent into a "subatomic universe" or "microverse," one of countless alternate universes accessible to Earth only by the mass-shunting process. Ultron/Pym used this ability to shrink inside theSun and take refuge in a Neutrino.^[140]

Size Increase: In addition, Ultron can also use the Pym Particles to grow significantly in size as well.^[143]

• Self-Duplication: Recently, Ultron displayed the ability to create several duplicates of himself, each with their own mind and consciousness separate from the control of the hive mind.^[17]

Ultron has one sole major weakness: an internal molecular re-arranger that renders the adamantium components of his internal workings more malleable, thus giving him a means to remodel or reconstruct his physical form. However, it has no effect on his outer armor, so it is virtually impossible to disable it from the outside. The chaos magic wielded by the Scarlet Witch has proven to be the sole exception thus far.^[25]

The metal-destabilizing ore known as Savage Land vibranium ("anti-metal").^[40]

While his adamantium body can survive super-extreme heat exposure, his internal circuits cannot.^[32]

Molecular Re-arranger: A ray capable of rendering Adamantium temporarily malleable; used to reconstruct or modify his physical form.

Roboticks: Insect-like drones that can devour human flesh.^[38]

In addition to that, Ultron has designed, built, and wielded a wide variety of high-tech tools, weapons, and accessories over time, such as his androne-mutation gas.
