Synopsis

What If... The Watcher Broke His Oath?

Plot

Golden Jaguar What If.png

While infiltrating Georges Batroc's ship, Peggy Carter is visited by Uatu, who has chosen her to fight against Ultron. In other universes, Uatu also visits and abducts T'Challa as he fights Ego during his expansion, Gamora as she melts the Infinity Gauntlet with Tony Stark and Eitri, Erik Killmonger just as Pepper Potts, Shuri and the Dora Milaje close in on him in Wakanda, and Thor during his brawl against Ultron Sentries in Las Vegas. The five are taken to a pub created by Stephen Strange, where he and Uatu brief them about Ultron's war on the Multiverse.

When Thor carries the head of a Sentry along with him, Killmonger takes it for himself. The newly-christened Guardians of the Multiverse devise a plan on confronting Ultron: Thor will lure him to their position as the team targets the Soul Stone for removal. Then, Gamora will utilize her Infinity Crusher to destroy the rest of the Infinity Stones. Afterwards, Uatu transports them to another universe to set their plan in motion as Strange enchants the team with an advanced protection spell. However, Thor accidentally gains Ultron's attention prematurely, forcing the Guardians to accelerate their plan as Gamora and Killmonger enter a portal crated by the Watcher.

Strange and Thor bombard Ultron with a swarm of Mjølnirs, allowing T'Challa to steal the Soul Stone. Strange then summons a horde of zombies on Ultron before the team depart to his home universe, where Natasha Romanoff intercepts the Soul Stone, believing the Guardians to be Ultron's lackeys. Carter reveals her close friendship to the Romanoff of her time, indirectly recruiting her to the team. Not long after, Ultron arrives to reclaim his missing Stone, having made quick work of the zombie horde.

Ultron attempts to destroy the galaxy with the five Stones, but is negated by Strange. As the AI and the Guardians wrestle for the Soul Stone, Strange manages to repeatedly nullify Ultron's attacks as the team pin him down, allowing Gamora to attach the Crusher onto the Stones. This fails as the Crusher was only designed to destroy the Infinity Stones of its original universe, allowing Ultron to recover the Soul Stone. He turns his sights on Strange and attempts to kill the sorcerer. Carter and Romanoff are blown away and land next to Romanoff's motorbike, where she finds the arrow infused with Arnim Zola laying beside it.

Romanoff gets Carter to expose Ultron's eye, allowing her to pierce it with the Zola arrow and have the HYDRA algorithm destroy the AI's codebase. However, Killmonger uses his Sentry Head to claim Ultron's armor and the Stones for himself. Zola-- who had assumed Ultron's body-- attempts to take them back, pitting the two in a deadlock struggle. Realizing that there is no way to truly win, Strange encapsulates Zola and Killmonger in a pocket dimension as Uatu teleports him back to his home. Strange assigns himself to observe the reality bubble, while Uatu sends the rest of his recruits back to their home universes.

Noticing a portrait of Steve Rogers, Carter considers heading back into her past, but Uatu convinces her to attend to her present day. Unable to restore Romanoff's world, Uatu instead places her in the universe where the Avengers had been assassinated, as Nick Fury, Carol Danvers and their Rogers fight Loki and the Asgardians. There, Romanoff steals the Scepter and uses it to subdue the God of Mischief. Meanwhile, Peter Quill joins T'Challa to fight Ego, Gamora and Thor reunite with Stark and Jane Foster in their respective realities, and Carter finds the HYDRA Stomper Armor stashed away on Batroc's ship with the help of her Romanoff. Reclaiming control of the Nexus of All Realities, Uatu vows to protect the Multiverse for as long as he can.
