Today Chris and Daniel recap episode 9 of MARVEL's What If...? This episode is titled "What If... the Watcher Broke His Oath?"

Summary:

The Watcher recruits Strange-Supreme, Captain Carter, Star-Lord T'Challa, "Party" Thor, Black Panther Killmonger, and a Gamora variant who killed Thanos[a] from their respective universes to battle Ultron. Ultron confronts them in a universe lacking intelligent life, where T'Challa steals the Soul Stone. Strange teleports in a zombie horde, including Wanda Maximoff, who Ultron overpowers. The team goes to Ultron's home universe, meeting Natasha Romanoff. Ultron follows, restarting the battle, where Gamora's Infinity Crusher device fails to destroy the Infinity Stones as they are from a different universe. Carter helps Romanoff shoot Ultron with an arrow containing Arnim Zola's mind. Zola wipes Ultron's mind and takes over Ultron's body. Killmonger steals the Infinity Stones for himself, but Zola fights him over them. Strange and the Watcher seal Killmonger and Zola in a pocket dimension, which Strange agrees to watch over. The Watcher returns Strange, Carter, T'Challa, Gamora, and Thor to their respective universes. Romanoff refuses to return to hers, so the Watcher brings her to one in which the Avengers candidates were assassinated,[b] where she helps defeat Loki. In a mid-credits scene, Carter and her universe's Romanoff discover the Hydra Stomper armor with someone inside.
