1. “What If… Ultron Won?”

Number: 8
Air Date: September 29, 2021
Starring: Jeremy Renner (Hawkeye), Benedict Cumberbatch (Doctor Strange), Toby Jones (Arnim Zola), Ross Marquand (Ultron)

Ultron, having taken Vision’s Mind Stone and vibranium body, has defeated the Avengers and launched a global nuclear holocaust. Thanos appears on Earth to complete the Infinity Gauntlet, but Ultron instantly kills him and takes his five Infinity Stones, thus gaining control of all six.

He uses them to create a massive army of drones and eradicate all life throughout the universe, leaving Carol Danvers, Clint Barton, and Natasha Romanoff as the only survivors. Danvers fights Ultron, but he also kills her.

Barton and Romanoff find a copy of Arnim Zola’s consciousness and try to upload it to Ultron’s mind to destroy him. Barton sacrifices himself to allow Romanoff and Zola, now in the body of an Ultron drone, to escape.

The charge fails because Ultron’s main body is no longer in his universe: Ultron has realized the existence of the multiverse and attacks the Watcher. They fight through the multiverse until Ultron gains the upper hand. The Watcher flees and reluctantly asks Strange Supreme for help.

Score: 9.5/10

2. “What If… Doctor Strange Lost His Heart Instead of His Hands?”


Number: 4
Air Date: September 1, 2021
Starring: Benedict Cumberbatch (Doctor Strange), Rachel McAdams (Christine Palmer), Benedict Wong (Wong), Tilda Swinton (Ancient One)

After losing his girlfriend, Dr. Christine Palmer, in a car accident, Dr. Stephen Strange travels to Kamar-Taj and learns of the Mystic Arts. He discovers the Eye of Agamotto, which can manipulate time, but the Ancient One and Wong warn him that doing so could destroy reality.

Two years later, Strange tries to use the Eye to save Palmer, but he always dies in all settings. The Ancient One tells Strange that Palmer’s death is an “absolute point” on the timeline that cannot be undone, but Strange refuses to listen.

Using the power of the Dark Dimension, the Ancient One divides Strange into two alternate versions: one where Strange accepts Palmer’s death while in the other he discovers how to gain power by absorbing mystical beings, becoming Doctor Strange Supreme. This evil version defeats the good Strange, absorbs him, and uses his power to resurrect Palmer, shattering reality.

Supreme Strange asks the Watcher for help, but he refuses to intervene. Palmer disintegrates and the universe collapses, leaving Supreme Strange crying in his loneliness.

Score: 9.1/10

The Watcher seeks out and recruits Captain Carter, Star-Lord T’Challa, Party Thor, Killmonger, and a variant of Gamora who killed Thanos from their respective universes, and along with Strange Supreme, establishes a team nicknamed the Guardians of the Multiverse to fight Ultron.

After the Watcher sent the team to an uninhabited world so they can prepare for battle, Thor accidentally draws Ultron’s attention to them. A battle ensues before T’Challa is able to steal Ultron’s Soul Stone, and the team escapes as a herd of zombies, including the zombified Wanda Maximoff, falls on Ultron to stop him.

Upon reaching Ultron’s home universe, they attempt to use the Soul Stone to power Gamora’s Infinity Crusher, but are interrupted by that universe’s Natasha Romanoff. Ultron finds them again, and an intense battle for the Soul Stone ensues, until Romanoff and Carter are able to shoot Ultron with the arrow containing Arnim Zola’s AI.

Zola eliminates Ultron from the inside, while Killmonger betrays the team and attempts to take the gems for himself. Zola, now in control of Ultron’s body, battles Killmonger for control of the Gems, until they are both frozen in a pocket dimension by Strange Supreme and the Watcher.

Strange Supreme returns to his collapsed universe to protect Zola and Killmonger for eternity. The Watcher then returns each Guardian to his own universe, with the exception of Romanoff, whom he brings to the universe where the original Black Widow was killed so that she can help restore peace to that Earth.

In a mid-credits scene, Carter discovers the Hydra Stomper armor, with someone inside.
