"Episode 4" is the fourth and final episode of the Disney+ streaming television miniseries Marvel Zombies. It was released on September 24, 2025, alongside the rest of the series.
The Nova Corps shoots down the spaceship, but the heroes are rescued by the sorcerers of Kamar-Taj, who reveal that the surging energy of the Infinity Stones is being contained by "Infinity Hulk". Wanda arrives, having amassed enough zombies to defeat him and take the Infinity Stones' power for herself. Infinity Hulk initially fights off the zombies but is soon overpowered. The heroes arrive to help defend him, but one by one, they fall to the overwhelming hordes. Infinity Hulk unleashes a powerful blast to defeat the zombie Thor, leaving him vulnerable and allowing Wanda to take his power. Despite her initial refusal, Kamala is persuaded by Wanda to help her remake the world. After a blinding explosion, Kamala wakes up and reunites with Riri and Kate, with things seeming to have gone back to normal. However, reality flickers, and the real Riri tells Kamala she has hacked the system, and that what she is seeing is not real.
