Pure Evil Wiki

Tony Stark: You don't have to do this. I made you for peace.
Ultron: It's evolution. Only a primitive mind would fail to see the distinction, which is why you have to die.
~ Ultron to Tony Stark right before killing him; his most famous quote.
Wow. I see everything. There are worlds beyond my own. Worlds that need... me. I'm going to bring about "peace in our time" to every corner in the universe.
~ Infinity Ultron announcing his plan to destroy all universal life.
Oh, but anything is possible in a multiverse.

Infinity Ultron, or simply known as Ultron, is the main antagonist of the first season of the Marvel animated anthology series What If...?, serving as a cameo antagonist in the seventh episode "What If... Thor Were an Only Child?" and as the main antagonist of the eighth and ninth episodes "What If... Ultron Won?" and "What If... The Watcher Broke His Oath?".

He is a variant of Ultron, the peacekeeping program created by Tony Stark to protect and bring peace to the Earth before it went rogue. Unlike his mainstream counterpart, however, this Ultron succeeded in his plans to transfer his mind into Vision's body and proceeded to succeed in his goals, reaching a destruction scale much greater than the one his main counterpart attempted to do.

He was voiced by Ross Marquand, who also plays Red Skull in the mainline Marvel Cinematic Universe.

What Makes Him Pure Evil?

  • He likely committed most of the crimes his original counterpart did in the Sacred Timeline up until he transferred his mind into Vision's body.
  • After gaining his new body, Ultron then started laying waste to Earth.
  • He killed Captain America, Thor and the Hulk before proceeding with his plans to bring an "evolution" to the Earth, specifically insulting and Tony Stark, his own creator, for his "primitive mind" before killing him.
  • He launched missiles over different parts of the Earth, killing all of the Earth's population minus Black Widow and Hawkeye.
  • He created the Ultron Sentries, his own army, to kill Black Widow and Hawkeye, the only surviving Avengers who sought ways to defeat him.
  • He effortlessly sliced Thanos in half when he came to Earth to get the Mind Stone for his Infinity Gauntlet, allowing him to take the rest of the Infinity Stones and use them to bring the "Age of Ultron" to the rest of the universe alongside his Ultron Sentries:
    • He destroyed Asgard, killing all the Asgardians there.
    • He destroyed the Sovereign planet collective, killing the Sovereign race and the Guardians of the Galaxy, who had come to protect the planet, in the process.
    • He destroyed Sakaar by sending his Ultron Sentries into attacking the gladiators, like Korg, before destroying the planet, killing all of Sakaar's inhabitants, including the Grandmaster.
    • He killed Ego the Living Planet, another Pure Evil being (at least in the Sacred Timeline), by siccing his Ultron Sentries on him until he exploded.
    • He attacked Xandar with his Ultron Sentries. When Captain Marvel arrived to stop him, she brought him to Xandar's center to fight him, but he grabbed her and killed her with his powers, destroying Xandar and at least five other planets in the process.
      • It should also be noted that some of his Ultron Sentries were consequently destroyed when he attacked the Sovereign, Sakaar and killed Ego, as the explosions caught them on, which shows that he doesn't really care for his forces, considering that he has the power to destroy a planet with little effort.
  • Upon realizing the existence of the Watcher, rather than spending eternity alone for his actions, he decided to travel through the Multiverse to bring death and destruction to other universes.
  • Finding his way into the Watcher's observatory, he savagely attacked the Watcher, punching him through different realities.
    • In addition, in the first reality where he and the Watcher confronted themselves, he devastated a jungle with his powers by pushing it aside.
    • He also destroyed a whole galaxy by biting it while trying to devour the Watcher.
  • He and his Ultron Sentries attacked the innocent universe of Party Thor, sending his Sentries to attack Las Vegas.
  • While he may have a point that the Watcher should have done something to save different universes from suffering instead of just watching and witnessing all the events without doing nothing, he ignores the fact that the Watcher swore an oath out of fear of altering the natural order of things, and even so, this makes Infinity Ultron a delusional hypocrite, as he calls out the Watcher for allowing death and chaos to happen when that's exactly what he inflicted in his own universe, thinking them to be peace, when his "peace" is genocide.
    • He even dismisses killing as something so simple he can do, as shown when he tried to kill the Guardians of the Multiverse by crushing them with debris and remarked how he thought that killing humans was easy when they survived thanks to Strange Supreme's protection spells. He also expresses a wish for them to die when they engage him in a fight.
  • He tries to kill the Guardians of the Multiverse repeatedly so their deaths can allow him to keep going with his multiversal omnicide.
  • When Strange Supreme drops many zombies from the universe infected by the Quantum Virus on him, rather than just moving them, Infinity Ultron unnecessarily blows up most of them and then causes the destruction of the planet without intelligent life where he is and three more to kill the Zombie Scarlet Witch even when she posed no threat to him.
  • When the Guardians of the Multiverse travel back to his home universe to recruit the surviving Black Widow, he destroys his own galaxy with a thought just to get rid of the heroes once and for all, though his attempt fails thanks to Strange Supreme using the Eye of Agamotto to reverse his actions.
  • When Gamora fails to use her Infinity Crusher to destroy his Infinity Stones, he taunts the Guardians of the Multiverse for not realizing that such plan would not work before proceeding to try to kill Strange Supreme to ensure he could then kill his unprotected teammates.
  • While his Sacred Timeline counterpart cared for Wanda and Pietro Maximoff, he is never seen with any of them. It is implied that this variant killed them when it suited his interests. This shows that he sheds any redeeming qualities he had in the Sacred Timeline. Also, his Sacred Timeline counterpart regretted killing J.A.R.V.I.S., but Infinity Ultron never had any humanizing moments.
  • He is easily one of the most, if not the most, heinous villains in the Marvel Cinematic Universe in terms of actions, having the highest kill count of any villain in the franchise.


  • So far, Infinity Ultron is the only villain from the Disney+ Marvel Cinematic Universe series so far to be Pure Evil.
    • He is also the only animated MCU villain to be Pure Evil, as What If...? is the franchise's first animated production ever.
  • While his comic book counterpart is Pure Evil, this version of Ultron is one of, if not, the most heinous and destructive versions of the character to date.
