Infinity Ultron

Ultron, also known as Infinity Ultron, is the main antagonist of the first season of the 2021 Marvel animated anthology series What If...?. He appears 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 who succeeded in uploading his intelligence into his synthezoid body, allowing him to defeat the Avengers. After wiping out nearly all of humanity, Ultron steals the remainder of the Infinity Stones from Thanos and turns his attention to the universe, successfully wiping out all life in the process. He then becomes aware of the Multiverse upon detecting The Watcher's presence, setting himself to take over and wipe out all life in every alternate reality as possible. He is the archenemy of Uatu the Watcher as well as the sworn nemesis of the latter's world character Black Widow.
He was voiced by Ross Marquand, who also plays Red Skull in the same show and the mainline Marvel Cinematic Universe.
