What If... Ultron Won?
8th episode of the 1st season of What If...?

"What If... Ultron Won?" is the eighth episode of the American animated television series What If...?, based on the Marvel Comics series of the same name. It explores what would happen if the events of the Marvel Cinematic Universe (MCU) film Avengers: Age of Ultron (2015) occurred differently, with Ultron using the Infinity Stones to eliminate all life in the universe after successfully transferring his consciousness into Vision's body. It also serves to set up the first season's finale, as Ultron finds a way to traverse to other universes (established in the previous episodes), threatening the balance of the multiverse. The episode was written by story editor Matthew Chauncey and directed by Bryan Andrews.
Jeffrey Wright narrates the series as the Watcher, with this episode also starring the voices of Jeremy Renner, Lake Bell, Toby Jones, Ross Marquand (Ultron), Josh Keaton, Mick Wingert, Alexandra Daniels, and Benedict Cumberbatch. The series began development by September 2018, with Andrews joining soon after, and many actors expected to reprise their roles from the MCU films. Animation for the episode was provided by Flying Bark Productions, Squeeze, and Stellar Creative Lab, with Stephan Franck serving as head of animation.
"What If... Ultron Won?" was released on Disney+ on September 29, 2021.
This brief starts where responsible research should: with the source description of “What If... Ultron Won?” as 8th episode of the 1st season of What If. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as 8th episode of the 1st season of What If. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 11, 2026. The linked authority identifier is Q108738871. 1 of 1 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 2015, 2018 and 2021.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
