It's not often in the MCU that one superhero in a band of others towers above the rest, but this is exactly what happens in Episode 9 of "What If...?," entitled "What If...The Watcher Broke His Oath."
At the start of the finale, the Watcher (voiced by Jeffrey Wright) recruits heroes from the previous "What If...?" tales in an attempt to defeat Infinity Ultron as he continues his onslaught of the multiverse. Doctor Strange (Benedict Cumberbatch) — now known as Strange Supreme following the events of Episode 4 — was the very first hero the Watcher recruited, and now we all see why.
The sorcerer is at the forefront of the Guardians of the Multiverse's battle with Ultron throughout the episode, and even manages to keep his fellow heroes safe with a protection spell during the worst of it. Strange Supreme spent centuries absorbing other powerful beings and their powers during Episode 4, and he uses these abilities in a number of ways during the finale.
At one point, the Doctor multiplies Thor's hammer in an attack on Ultron. He later unleashes a trio of fire-breathing dragons onto the big baddie before straight up swallowing and eating a blast attack from him like it's a potato chip. "Wait, what?!" Ultron shockingly asks himself after seeing Strange's unlimited power. It's a display of shock that shows just how powerful Strange Supreme really is, especially compared to beings like Ultron and even the Eternals.
