The What If...? season 2 finale begins with a brand new Marvel Animation fanfare mostly comprised of footage from this latest batch of episodes. However, we also get to see T'Challa Star-Lord and, weirdly, Red Guardian (who doesn't appear in this show but is expected to be a major part of Marvel Zombies).
It concludes with Captain Carter taking Captain America's place, a fitting decision seeing as she's key to "What If... Strange Supreme Intervened?"
In 1602, Doctor Strange tells Peggy about a threat to the Multiverse like any other before transporting her to his Sanctum Infinitum. He's been collecting universe killers such as Infinity Ultron, but one has escaped and Strange needs Cap's help tracking them down.
We then visit a world where HYDRA won the war and laid waste to the world (Red Skull's image even adorns Mount Rushmore) and it's there we find Kahhori! She's stranded in the wrong reality and tells Peggy that Strange is lying, capturing righteous heroes as well as universe killers to feed them to a forge which will rebirth the reality he destroyed.
Discovered, Strange shows his true colours and Peggy frees many of those trapped Variants, including a bizarre-looking Hulk, a monstrous Rocket, and the returning zombie Scarlet Witch. We see a version of Hela take control of those zombies before clashing with Surtur and Cap and Kahhori later encounter the Killmonger who stole Infinity Ultron's suit in What If...? season 1.
Kahhori teleports him out of the suit and sends him into battle with all those other Variants, giving us a taste of what Avengers: Secret Wars could look like (we even see some Thor vs. Thor action).
Peggy then takes control of the Infinity Stones and battles Strange; he tries posing as Steve Rogers to throw her off guard and, while she sees through it, the distraction allows him to begin feeding those Variants into the forge. Luckily, Kahhori can counteract him and, using her powers to wield Mjolnir and the Ten Rings (Peggy, meanwhile, dons Hela's crown and wields The Hulk's sword), they're all sent back to their respective realities.
Strange is no longer able to hid his monstrous true form as his grief has grown too powerful. Captain Carter dispatches him with a well-placed Infinity punch and, as he falls into the forge, the Sorcerer Supreme pulls his grief in with him and finally accepts his fate by conquering his demons.
As a result, Strange's world - and Christine Palmer - are reborn...without him. The Watcher explains that he was never born in that reality and never will be. He saved Peggy and Kahhori before Sanctum Infinitum blew up and shows Cap the Multiverse which has now taken on the same tree-like form we saw in Loki.
Peggy suggests they take the scenic route home, suggesting there are more Multiversal adventures to come...we just hope it wasn't this Variant on Earth-838!
In terms of the cast, we have Hayley Atwell as Captain Carter, Benedict Cumberbatch as Strange Supreme, Devery Jacobs as Kahhori, Cate Blanchett as Hela, Clancy Brown as Surtur, and Stanley Tucci as Dr. Erskine. The major recasts are Josh Keaton as Captain America and Feodor Chin as Wenwu.
