"The entire Multiverse at your fingertips, and you spent all your time up there? Wow. Isn't this more fun than just watching? And to be honest, a lot less creepy on your part. The boundaries of the multiverse are irrelevant to beings like you and me. I didn't evolve by staying inside the lines. Run, watch, it doesn't matter. From here, I can see everything. No one can stop me now."
Ultron to The Watcher

What If... Ultron Won? is the eighth episode of the first season of What If...?.

Synopsis

Natasha Romanoff and Clint Barton seek to destroy the killer-robot Ultron following a cataclysmic event.

Plot

Ultron absorbs the Infinity Stones

Ultron successfully uploads himself into a new body made out of vibranium. Armed with the Mind Stone, the rogue AI manages to kill Thor, Bruce Banner, Steve Rogers and Tony Stark before unleashing Earth's entire arsenal of nuclear weapons upon humanity, leading to their decimation. When Thanos arrives on Earth with the other five Infinity Stones, Ultron effortlessly kills him with the Mind Stone and takes the Stones for himself. Ultron's newfound omnipotence makes him aware of the greater universe.

Ultron thus expands his mission to bring his version of peace to all corners of the cosmos. Spawning a fresh army of Ultron Sentries with the Reality Stone and creating a spherical spaceship, Ultron initiates his conquest, inflicting his will on every inhabited world of the universe. Asgard, the Sovereign, Sakaar and Ego are just some of the countless planets that fall to the genocidal AI. During his Xandar invasion, Carol Danvers attempts to destroy Ultron by ramming him into the planetary core. However, she is killed when he uses the Stones to obliterate the planet. After remaking all of the universe in his image, Ultron is left as a program without a purpose. But when he notices Uatu's presence, he learns of alternate realities within the Multiverse. Alarmed, The Watcher decides to turn his attention to that universe's last hope as the AI actively tracks him down.

The KGB Archive Building

Natasha Romanoff and Clint Barton are the only known survivors of the nuclear holocaust, spending the remainder of their days outrunning the Sentries. In Moscow, they infiltrate the KGB archives and attempt to find intel regarding an AI that can take on Ultron. After searching through countless numbers of files for hours, Romanoff locates the file on Dr. Arnim Zola, to Uatu’s relief as he observes. Determining Zola as a viable combatant to Ultron, Romanoff and Barton head to a HYDRA facility in Siberia, containing a second set of databanks for Zola's mind outside Camp Lehigh.

After activating the algorithm, Romanoff and Barton coerce Zola to help them destroy Ultron from the inside. After downloading Zola into one of Barton’s arrows, Romanoff lures the Sentries to the base, enabling Barton to transfer Zola to one of the Sentries and allow him to invade the hive code. Despite this, Zola is unable to execute his task, as Ultron has left their universe. As the Sentries swarm the facility, Barton-- having lost his will to live after the death of his family-- sacrifices himself to destroy the robot horde, buying Romanoff and the Zola sentry ample time to escape.

Uatu fights Ultron

Simultaneously, Ultron confronts Uatu in the Nexus of All Realities. In their fight, Uatu teleports to numerous universes in a futile attempt to flee. Ultron gains the upper hand as he mocks Uatu for the oath he swore preventing him from interfering before attempting to kill him. But Uatu manages to break free and escape to another universe, where he finds Stephen Strange, who beckons him to break his oath. With Ultron's ambitions threatening the Multiverse as a whole, Uatu reluctantly agrees and asks the sorcerer for help. Elsewhere, Ultron had taken control of the Nexus and now has all realities at his fingertips.

Trivia

  • This is the first episode of What If...? that does not feature a closing narration from The Watcher.
  • The universe depicted in this episode has several inconsistencies with the main universe:
    • Black Widow is seen in a recap with other Avengers and the Regeneration Cradle, when in Avengers: Age of Ultron, she had been captured by Ultron at that time.
    • During the shot where Uatu explains how Vision was created in the Sacred Timeline, Scarlet Witch and Quicksilver are notably absent, when they were present for this scene in Age of Ultron, and it was Wanda reading Ultron's thoughts through Vision's body that cued her in to Ultron's true plans.
    • Ego is shown being attacked and killed during Ultron's campaign against all life in the universe, although he should have already been killed a year earlier as shown in Guardians of the Galaxy Vol. 2, which takes place before Age of Ultron.
    • The Guardians of the Galaxy are shown on Sovereign presumably conducting their mission there as seen in the opening scene of Guardians of the Galaxy Vol. 2. This also occurred a year before the events of Age of Ultron and before they crossed paths with Ego.
    • Thanos is seen wielding the nearly-complete Infinity Gauntlet at the time of Age of Ultron. In the main timeline, he would not begin his quest until three years after Avengers: Age of Ultron, during Avengers: Infinity War.
      • The Tesseract, and with it, the Space Stone, was located on Asgard during the events of Age of Ultron.
      • Despite the Power Stone being located on Xandar in the main timeline, which Thanos destroyed to acquire it off-screen in Infinity War, the planet is shown to be intact, and is, in fact, the last surviving world to be attacked in Ultron's genocidal campaign.
      • Thanos is shown to be in possession of the Time Stone, which at the time of Age of Ultron, would have been in the possession of the Ancient One.
      • Thanos is also shown with the Reality Stone, which at the time should be in the possession of the Collector in Knowhere.
      • Although Thanos has the Soul Stone, Gamora is shown to be alive battling Ultron Sentries with the Guardians of the Galaxy on Sovereign.
    • The story of the episode is similar to the What If...Age of Ultron? comic.
      • The first issue had a universe where Wasp died making Hank Pym creating a more vicious Ultron. This leads into a world where Ultron successfully destroys all life on Earth. Later in the comic Ultron learns of the multiverse and invades the other universes that were shown in the comic only to be defeated by the multiversal hero team, Avengers Infinity. This is similar to this episode where Ultron is also successful in killing all life in his universe, until he learns of the multiverse. He continues his quest to kill all life across the entire multiverse until he was defeated by a multiversal hero team, the Guardians of the Multiverse.
