"Episode 3" is the third episode of the Disney+ streaming television miniseries Marvel Zombies. It was released on September 24, 2025, alongside the rest of the series.
In a flashback, Peter Parker, Scott Lang's head, and T'Challa arrive in Wakanda only to see it conquered by a zombie Thanos. The trio fight him alongside Thor, Rocket Raccoon, and Groot. Thanos kills Groot, Rocket, and gravely injures Thor before attempting to snap the Infinity Gauntlet. T'Challa sacrifices himself to push Thanos into Wakanda's vibranium core, destroying the Infinity Stones and releasing a surge of energy. Peter and Scott are saved by the remaining sorcerers of Kamar-Taj. In the present, Kamala and her group reach New Asgard, with Blade convincing Valkyrie to let them in by way of the god Khonshu. The Asgardians have been feasting thanks to a gift from the Queen of Sokovia, Wanda herself. The food, revealed to be zombie remains, infects the Asgardians and Alexei, who then kill Zemo, Woo, and Death Dealer. The heroes flee while Thor fights Wanda, escaping in an Asgardian ship into space. They activate the transmitter, but the already stationed Nova Corps reveal that Earth has been condemned and quarantined, before attempting to kill them.
