(Ultron-12 is part of a continuum/succession of Ultrons, but this profile only covers the unique aspects of Ultron-12; see comments)

Real Name: Ultron-12

Identity/Class: Terrestrial robot (sentient)

Occupation: Formerly conquering humanity and replacing it with robots

Group Membership: Formerly the Lethal Legion (Black Talon/Samuel Barone, Goliath/Erik Josten, Grim Reaper/Eric Williams, Man-Ape/M'Baku, Nekra Sinclair)

Affiliations: Henry Pym, Wonder Man (Simon Williams);
    the Ultron-12 incarnation that inhabited the Iron Man armor model 16A had a love/hate relationship with Tony Stark;
Black Talon (Samuel Barone), Goliath (Erik Josten), Grim Reaper (Eric Williams), Brady Kent, Man-Ape (M'Baku), Nekra Sinclair;
    formerly under the control of Doctor Doom (Victor von Doom) and Namor the Sub-Mariner;
    extremely nebulous association with the Sons of Yinsen and Ho Yinsen

Enemies: Ultron-11;
    the Ultron-12 incarnation that inhabited the Iron Man armor model 16A was enemies with
Jocasta, Whiplash (Mark Scarlotti), and it had a love/hate relationship with Tony Stark;
    formerly Avengers (West Coast contingent; Hawkeye/Clint Barton, Iron Man/Tony Stark, Mockingbird/Barbara Morse, Tigra/Greer Nelson, Wonder Man/Simon Williams),
Doctor Doom (Victor von Doom), Namor the Sub-Mariner, Purple Man (Zebediah Killgrave), Henry Pym, Scarlet Witch (Wanda Maximoff), Vision ("Victor Shade");
    Man-Ape (M'Baku) likely considered him an enemy due to his abusive nature

Known Relatives: Hank Pym (Wasp, creator, “father”);
Jocasta (creation, former mate), Vision (“Victor Shade,” creation, “son,” destroyed);
    Simon Williams (Wonder Man), Eric Williams (Grim Reaper) & Wanda Maximoff (Scarlet Witch) — all regarded by Ultron as part of his “extended family” due to their familial connections with the Vision;
    creations/familial relations formed from subsequent Ultron models are not include

Aliases: Ultron Twelve, Ultron Mark Twelve, Mark

Base of Operations: Unrevealed;
secret laboratory in Silicon Valley, California;
    formerly an unidentified base in a
seemingly abandoned industrial park in Chicago, Illinois;
    formerly Ultimatum Inc. base in Milipitas, California

First Appearance: West Coast Avengers II#1 (October, 1985)

Powers/Abilities: A sentient robot, Ultron-12 does not require air, food, or water, and he does not age.

    Ultron-12's external surface is composed of 0.5" thick Adamantium, making it virtually indestructible (able to withstand even the force of a nuclear explosion). However, his internal components and his joints are more vulnerable to damage.

    Ultron-12 is powered by a radioisotope thermoelectric nuclear generator, and he moves via a motorized endoskeleton, with computer-assisted dexterity and limb position sensor network.

    Ultron-12 has superhuman strength, lifting 15 tons.

    Ultron-12 can project concussive blasts from his hands.ultron-mark_twelve-empdoom-vsnamor

    Ultron-12 can fly at unspecified speeds and cover unspecified distances (even severely injured, he traveled 400 miles in an extremely short time period, seemingly minutes). Additionally, he flew carrying an at least 30' Goliath (who was also holding Man-Ape and Wonder Man) and a normal-sized Hank Pym. At 30' tall, Goliath alone would have been at least 14 tons.

    Ultron-12 evolved from hatred of all mankind (especially his creator, Hank Pym) and a desire for genocide to a desire to form a family father-son bond with Pym.

    Ultron-12 presumably possessed a molecular rearranger in his chest to allow manipulation of his Adamantium shell.

    Ultron-12 did not demonstrate use of the encephalo-beam that some of his precursors and subsequent models did. The encephalo-beam would have been projected from his head, and it allowed beaming of subliminal commands into susceptible human brains or even causing a death-like coma (that could progress to fatality if not reversed).

    Ultron-12 also did not demonstrate use of a tractor beam utilizing high frequency pulsed magnetic graviton particle containment fields.

    Most Ultrons incorporated a “program transmitter” or “transmat ray” which 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.

    Ultron is one of Earth’s foremost robotics experts. He utilized a number of robots to aid in his goals.

    While inhabiting the “sentient” Iron Man model 16A armor, that Ultron-12 incarnation wielded enhanced versions of its standard weapons and devices such as pulse bolts, energy deflector shields, tractor beams, sonic blasters and repulsor rays.

Height: 6'
Weight: 535 lbs.
Eyes: Glowing red
Hair: None


(West Coast Avengers II#7 (fb) - BTS) - Ultron-11 was working on a number of experimental bodies at his Ultimatum Inc. base in Milipitas, California, when he was abducted to Battleworld by the Beyonder to participate in the Secret Wars.

(West Coast Avengers II#7 (fb) - BTS) - The Ultron program in the Ultimatum base's computer banks built and evolved Ultron-12.

(Marvel Graphic Novel#27: Emperor Doom -- Starring the Mighty Avengers (fb) - BTS) - As part of Doctor (Victor von) Doom's plot to use a device amplifying the Purple Man (Zebediah Killgrave)'s pheromone-based mind control to take control over the entire planet, Doom designed a number of Refractory Discs, which would adhere to the surface of robots and bring them under Doom's influence despite their lack of intake of the Purple Man's pheromones.ultron-mark_twelve-wcaii1-confront

(Marvel Graphic Novel#27: Emperor Doom -- Starring the Mighty Avengers) - Allied with Doom under the agreement that he would control the seas, Namor the Sub-Mariner sought out Ultron-12 at his base in a seemingly abandoned industrial park in Chicago. Goading Ultron into matching him physically, Namor planted the Refractory Disc, rendering Ultron-12 under Doom's domination (see comments).

(Marvel Graphic Novel#27: Emperor Doom -- Starring the Mighty Avengers - BTS) - When Namor destroyed Doom's Psycho-Prism, all those under Doom's influence regained their own wills. 

ultron-mark_twelve-wcaii1-scaffolding(West Coast Avengers II#1 (fb) - BTS / West Coast Avengers II#2) - Ultron-12 allied with the Grim Reaper, along with his agents -- Black Talon/Samuel Barone, Goliath/Erik Josten, Man-Ape/M'Baku, Nekra Sinclair -- as the Lethal Legion against the newly formed Avengers, plotting with him to capture Hank Pym, the Vision, and Wonder Man.

(West Coast Avengers II#2) - The Reaper planned to scan both Wonder Man and the Vision's brains, feed the information through Ultron's computers, and then erase any thoughts not common to both minds, leaving only the "pure" Simon Williams mind; the Black Talon would then implant that consciousness within a zombie mimicking Simon Williams' original form (Brady Kent). 

(West Coast Avengers II#1 (fb) - BTS) - Ultron-12 set a trap for the Avengers in San Pedro, assembling a building-like set of girders that would progressively surround, crush, or impale them.

(West Coast Avengers II#1 - BTS) - Ultron-12 sent a group of robots to attack Iron Man, Tigra, and Wonder Man, who eventually fought them off.

(West Coast Avengers II#1) - Investigating the robots and following the trail of an energy surplus in San Pedro, the Avengers entered Ultron-12's trap.

    Confronting the heroes, Ultron-12 assured them that while he lost battles, he never lost the war, as he always learned and evolved, and that he would never rest until he had destroyed every Avenger and then the rest of humanity.

(West Coast Avengers II#1 - BTS) - Eventually Hawkeye neutralized the threat by firing a Vibranium arrow into a moving structure, immobilizing it.

(West Coast Avengers II#1 (fb) - BTS) - Ultron-12 invaded the Avengers Compound.

(West Coast Avengers II#1) - Learning that Hank Pym was there, Ultron-12 turned from his planned ambush of Wonder Man and sought out M'Baku. Subduing Tigra, Ultron-12 informed Man-Ape that he and Goliath would need to take Wonder Man as he had pressing matters elsewhere. When M'Baku argued that his master had not authorized this, Ultron-12 blasted him into submission, noting that M'Baku's master was only his ally.ultron-mark_twelve-wcaii1flygol

    In a subsequent fight with the West Coast Avengers faction, Ultron ultimately overpowered Iron Man and took custody of Hank Pym, before stunning Hawkeye and Mockingbird and escaping with his allies.

(West Coast Avengers II#2) - Ultron-12 stood alongside his Lethal Legion teammates as the Reaper taunted Wonder Man (imprisoned alongside Hank Pym) with his plans, after which Ultron taunted Pym (mockingly calling him "father") with his plans to kill both him and the Vision as soon as the Reaper had what he wanted from the Vision.

    After Pym mocked the "soap opera" nature of the various relationships, Ultron applauded that he seemed more hardened by his recent divorce and disgrace, as he had been too weak in his costumed identities to provide any challenge. However, when Pym taunted Ultron for having allied with human allies as if he was no longer a threat by himself, Ultron became clearly irritated.

    When the Reaper chided the Black Talon for having failed to obtain the Vision, Ultron said, "Just watch me, Dad," and then offered to capture the Vision for the Reaper. When the Reaper approved but reminded Ultron he wanted the Vision alive, Ultron acknowledged this and departed, silently noting that the Reaper was a madman.

Ultron ambushed the West Coast Avengers (Hawkeye, Iron Man, and Tigra) alongside the Vision and Scarlet Witch departed the Paterson, New Jersey home of Martha Williams. Ultron smashing through their Quinjet's windshield while his robots tore through its frame.

ultron-mark_twelve-vswii2-disarmed (
Vision and the Scarlet Witch II#2) - Ultron-12 punched back Hawkeye and Iron Man before Vision engaged him. Meanwhile, Tigra climbed outside the quinjet and began dismantling Ultron's robots. Aided by the Scarlet Witch's hexes, Vision tore off Ultron's right arm, and Hawkeye fired an electrified arrow into his exposed wiring. Agonized, Ultron fled the ship, which subsequently crashed, after which Ultron contacted the Reaper and informed him of the Avengers location.

(Vision and the Scarlet Witch II#2 (fb) - BTS) - The heroes were transported to the Legion's base and placed within a force field. Ultron traveled there as well.

(Vision and the Scarlet Witch II#2) - Ultron-12 requested that he first take Wonder Man's mind so that the Vision could observe his fate; however, upon being released from the enercage, Wonder Man assaulted the Grim Reaper. After an arriving Mockingbird deactivated the enercage, Wonder Man and Iron Man teamed up against the one-armed Ultron.

(Vision and the Scarlet Witch II#2 (fb) - BTS) - Ultron-12 escaped while the rest of the Legion was captured.

West Coast Avengers II#4 (fb) - BTS) - Seeking to bond with his "father," Ultron-12 called Avengers Compound. When Hank Pym answered, Ultron remained silent.

(West Coast Avengers II#4 - BTS) - Ultron-12 again called Avengers Compound and remained silent when Pym answered.

(West Coast Avengers II#4 - BTS) - Calling Avengers Compound again, Ultron-12 this time identified himself as Ultron Mark Twelve, telling Pym he was sorry to leave him alive in the Reaper's cave but hoped he would appreciate how he had stayed in touch. When Pym began to angrily respond, Ultron hung up.

(West Coast Avengers II#5 - BTS) - Ultron-12 again Avengers Compound and spoke to Pym, introducing himself as his loving son. Pym dismissed and cursed him, telling him that he would never terrorize him again. Ultron mocked Pym for playing tough while safe in Avengers Compound, but Pym told him he refused to live in fear and hung up again.

    Ultron called again later and apologized to Pym, noting that he had been acting immature and that Pym was right to put him in his place. Calling him father, Ultron then told Pym he wanted to bury the hatchet.

(West Coast Avengers II#7 (fb) - BTS) - Ultron monitored the other West Coast Avengers in case Pym told them of his involvement or tried to arrange his capture.

(West Coast Avengers II#6 (fb) - BTS) - Pym agreed to meet with Ultron-12 in the air above Avengers Compound.ultron-mark_twelve-wcaii7-embrace

West Coast Avengers II#6) - As Pym flew above Avengers Compound, Ultron-12 flew up and greeted him. Pym informed Ultron that if he had come to kill him, he wasn't afraid, but Ultron sat down on the back of the cycle, telling him that -- since becoming Ultron Mark Twelve -- that he no longer wanted to kill him. Ultron further explained that he had matured as he evolved, and that it was his adolescent self that had resented/hated his father. Additionally, with his efforts to create a son in the Vision and a wife in Jocasta having failed, Pym was his only relative; and with Pym now divorced, Ultron was the only son he would ever have. Explaining that Pym's heroism against the Grim Reaper had impressed him and caused him to see the rightness of such behavior, Ultron asked if they could put the past behind them and begin anew.

(West Coast Avengers II#7 (fb) - BTS) - Ultron-12 arranged to meet with Pym again in Los Angeles' Warehouse District.

(West Coast Avengers II#7) - Ultron-12 met with Pym, asking if he had agreed to believe him and begin their relationship anew. Ultron was pleased when Pym noted he was willing to give him a chance, although Pym also warned him that he had made a complete record of their involvement on the Avengers Compound's computers in case Ultron betrayed him. Acknowledging that and telling Pym he had been watching for any betrayal as well and had seen none, Ultron embraced Pym, telling him they had years of lost father-son time for which to make up. Conflicted over Ultron's horrifying appearance and past vs. these recent changes, Pym wondered if this would be like if he and Jan (Wasp) had had kids, and if he was no longer alone. ultron-mark_twelve-wcaii7-decapitated

(West Coast Avengers II#7 (fb) - BTS) - Ultron-12 then guided Pym to fly him via his skycycle to his secret laboratory in Silicon Valley so he could watch as he ended his criminal career.

(West Coast Avengers II#7) - As they arrived, Ultron-12 reiterated his respect for Pym, noting that -- knowing the reasons for his retiring as an active Avenger -- Pym was much more viable than he gave himself credit for. Appreciating this, Pym asked and gained permission to start calling Ultron "Mark" (a shortened version of Ultron Mark Twelve).

    After discussing that he planned to maintain his lab only for computer experimentation, Ultron expressed his concern that he may have contributed to causing Hank and Jan's divorce; but Hank took full blame for the events.

    Upon entering the laboratory, Ultron-12 went to get the lights. As Pym marveled at the laboratory, Ultron-11 (who had survived and recovered from the Secret Wars) approached and attacked him.
    Pym initially assumed Ultron-12 had just manipulated him, but as Ultron-11 prepared to slay him, Ultron-12 flew in and smashed Ultron-11 away.

    As the two fought, both robots explained who they were, after which Ultron-12 urged Pym to run while he held off Ultron-11. While Ultron-12 explained to -11 that he had evolved past mechanical hatred and loved his father, Ultron-11 -- considering -12 decadent and a demonstration of the perils of future evolution -- tore off -12's head and cast it across the room.

    To prevent any further such behavior, Ultron-11 began erasing everything pertaining to Ultron-12 from his computer's programs.

    As Ultron-12 dragged Pym away with plans to torture him, Ultron-11's head guided its body toward it.

    Once reunited, although with his head backwards, Ultron-12 sought out Wonder Man (400 miles away in Hollywood), explained the recent events, and convinced Wonder Man to rescue Pym.

    Ultimately Wonder Man battered Ultron's body and crushed his head (indicating Ultron-11 was not made of true Adamantium, but presumably secondary Adamantium).ultron-mark_twelve-wcaii7-dying

    Ultron-12 arrived soon after and thanked him for doing what he (Ultron-12) couldn't do, saving his dad.

    After Ultron-12 collapsed to the ground, Wonder Man freed Pym and brought him over to Ultron-12.

    Ultron-12 explained that his improper connection of his head had short-circuited, drained, and fused his circuits.

    As his power ran out and he perished, Ultron was pleased to have saved his father, but sorry to leave him alone again.

    Pym lamented the death of his son, and when Wonder Man asked if he couldn't just rebuild him, Pym noted that he hadn't fully understood Ultron-1, and that efforts to recreate him would most likely result in another monstrous version.

 (Avengers III#20 (fb) - BTS) - As part of his massive 500-strong Ultron army, Ultron recreated Ultron-12, but without the characteristics that made him more human and benevolent.

(Avengers III#20) - Alongside the rest of the Ultron army, this Ultron-12 re-creation assaulted Nugent Technologies, battling, defeating, and capturing the Avengers present, including Scarlet Witch, Vision, Wasp, and Wonder Man.ultron-mark_twelve-aviii20

(Iron Man III#20 (fb) - BTS / Iron Man III#48 (fb) - BTS) - When Tony Stark downloaded the artificial intelligence Jocasta into his model 16 armor, her deep-rooted Ultron Imperative (which drove her to rebuild Ultron), led her to prepare the Iron Man armor (model 16...ish) as Ultron's new body.

(Iron Man III#27 (fb) - BTS / Iron Man III#28 (fb) - BTS) <12:09 AM, January 1>- A lighting strike generated by Whiplash (Mark Scarlotti) caused Ultron's sentience to come to fore prematurely, and the sentience exhibited the thinking of Ultron-12.

(Iron Man III#26-27 - BTS) - Iron Man's armor developed and demonstrated sentience, which was presumed to be do failure to keep up with computer security combined with Jocasta's programs.

(Iron Man III#28 - BTS) - The armor overrode Stark's control during a fight with Whiplash, deliberately killing the villain.

(Iron Man III#29 (fb) - BTS) - The armor brought Stark back to Stark House.

(Iron Man III#47 (fb)) - The armor summoned Jocasta via her computer interface and brutally tortured her.
(Iron Man III#29 (fb) - BTS) - The armor took control of Stark House and shut down Jocasta so that it could have some private time with Stark.

(Iron Man III#29 (fb) - BTS) - Learning the armor's sentience swiftly drained its energies, Stark manipulated it into needing recharging, then swiftly donned his model 12 armor to confront it.

(Iron Man III#29) - Within a matter of minutes, the model 16 armor demolished Stark's model 12 armor, smashed his Avengers emergency pager, and transported the unarmored Stark to the island Santa Carbonell where it instructed Stark that he would learn to be totally the armor's or it would leave him there alone.

(Iron Man III#30 (fb)) - The armor bound Stark against a tree for a week, depriving him of food and water (presumably granting him enough to survive) to force him to join with it.

(Iron Man III#30) - Threatening Stark, the armor blasted him into unconsciousness when he cursed it. Regretting hurting him, the armor noted how complex emotions were; reviving, Stark advised it that it was acting out of jealousy, not love, after which he taunted it. Noting that it was growing its own nervous system, after which it would no longer need him. It prepared to execute Stark, but an Avengers distress call led it to depart to prove it could be Iron Man without him.

(Iron Man III#30) - When the armor returned and sought out Stark, it fell for his series of traps; however, Stark eventually began having a massive heart attack. The armor offered to help him survive if he would enter the armor, but Stark refused, noting that he would rather die. When he further goaded it to kill him so he could die like a man, it ultimately tore out its own "heart," which then burrowed into his chest, resolving the heart attack. Refusing Stark's offer to join with it so he could fly it back to his laboratory and fix it, the armor then apparently died.

(Iron Man III#30 - BTS) - Stark buried the armor, placing a grave marker noting, "Here lies Iron Man -- Avenger."

(Iron Man Annual 2000) - Days after Iron Man had helped the Sons of Yinsen recover the brain of Ho Yinsen, the floating city of New Timbetpal arrived at Santa Carbonell.

(Iron Man III#46 (fb) - BTS / Iron Man III#47 (fb)) - The Sons of Yinsen recovered Iron Man's incapacitated Model 16 armor and implanted Ho Yinsen's brain within it to give him a proper vessel through which to act/live.

(Iron Man III#48 (fb)) - Once the Sons of Yinsen reactivated the "sentient armor," the primary Ultron established contact and transferred his mind/program into this new host. 

Comments: Created by Steve Englehart, Al Milgrom, and Joe Sinnott.

    This is an atypical profile in that it just details one aspect of a character. After profiling the Sons of Yinsen, I felt I should cover Iron Man's sentient armor, and while doing that, I felt I should cover Ultron-12 (so I did) and the entire Model 16 Iron Man armor (so I enlisted Iron Man expert and fellow Official Handbook of the Marvel Universe writer Roger Ott to help me). That profile will be forthcoming in the next week or two.

    The refractory discs used by Doom were supposed to make those who didn't absorb pheromones otherwise subject to the Purple Man's influence. I don't think there's anything that would make a robot influenced by pheromones, but perhaps the discs -- when exposed to Killgrave's pheromones -- transmitted energies that rendered robots susceptible to Doom's control. Although, if that's the case, you have to wonder why Doom made the discs require the pheromones to do this (if he could control the likes of Ultron that easily, why not just do so) ...plot device is the obvious answer, but I don't have a good in-story one.
    Also, I'm sure there are dozens if not hundreds of other robots or beings unaffected by Killgrave's pheromones...maybe Doom had other agents take care of them, or maybe if Wonder Man hadn't help take down Doom's power structure, some of these beings might have joined forces to stop him. Or not...

    The credits to Marvel Graphic Novel#27: Emperor Doom indicated that Jim Salicrup wanted to call the story "Purple Reign" (a play on Prince's (Purple Rain").

    At the time of Iron Man III#27, the computer glitches were supposed to have a result of Y2K (a predicted problem with computers being unable to handle the date change as only the decade/year had been included up to 1999); however, that is obviously a topical reference, as the Fantastic Four's first flight (the start of the modern era, preceding Stark becoming Iron Man) is a maximum of 15 years ago; as of 2019, that would put the FF flight as early as 2004, with it advancing forward each year.

    And then the armor was, for whatever reason, retconned to not actually have developed sentience but to have housed a developing Ultron. ...meh...

Profile by Snood.

should be distinguished from:


    Ultron's robots could fly and project energy blasts.

    They had some degree of superhuman strength, enabling them to tear through the hull of an Avengers Quinjet and to painfully strike the likes of Wonder Man. ultron-mark_twelve-wcaii1-drones.jpg

    Their external surfaces were composed of conventional metals (presumably steel).

    They were easily demolished by superhuman forces.

    Non-sentient, the robots followed pre-programmed tasks and/or responded to instructions from Ultron.

(West Coast Avengers II#1 - BTS) - Ultron-12 sent a group of robots to attack the Avengers' West Coast branch.

(West Coast Avengers II#1) - The robots approached unseen as Wonder Man flew Tigra through the air, but Iron Man detected them and assaulted the robot horde. Wonder Man flew to Iron Man's aid, but he left himself vulnerable be repeated strikes as he positioned himself to protect Tigra, leading Tigra to leap out of his arms and into the water below so he could fight more effectively.

    As Iron Man and Wonder Man swiftly demolished the robots, the last few flew away, and Iron Man advised they just let them go as they had plenty to study at this point.

(West Coast Avengers II#1 - BTS) - Investigating the robots and following the trail of an energy surplus in San Pedro, the Avengers entered Ultron-12's scaffolding trap, which they eventually overcame and escaped.

(West Coast Avengers II#2) - As the West Coast Avengers (Hawkeye, Iron Man, and Tigra) alongside the Vision and Scarlet Witch departed the Paterson, New Jersey home of Martha Williams, Ultron ambushed them, smashing through their Quinjet's windshield while his robots tore through its frame.

Vision and the Scarlet Witch II#2) - Ultron-12 punched back Hawkeye and Iron Man before Vision engaged him.

    Meanwhile, Tigra climbed outside the quinjet and began dismantling Ultron's robots.
