The Day the Earth Disappeared is a the seventh episode of season 10 of the 1987-1996 series. It originally aired at CBS on 26 October 1996.


The Turtles surface just as a massive earthquake rocks the entire city, tearing streets apart and raising volcanoes. The Dreggnaught appears overhead and the Turtles battle the Batmen, before Dregg appears and defeats both Leonardo and Raphael, and then seemingly kills all four of them. It turns out that what he killed were extremely realistic holograms, allowing the real Turtles to get the drop on him.

After being forced into retreat, Dregg reveals that he's planning to use his transporter to teleport Earth into a Dimension X solar system. In this way, he's hoping that he'll be able to finally defeat the Turtles. A space warp starts appearing near the Earth, growing large enough to swallow the planet in just a few hours. 

Donatello attempts to trace the origin of the warp, but Dregg uses a black hole's gravity to pull Leonardo, Donatello and Splinter inside. Donatello and Leonardo end up on a planetoid, while Splinter ends up on Dregg's ship. 

Raphael and Michelangelo fall through the black hole several minutes later, finding themselves separated from their brothers, and all four Turtles are confronted by various monsters. Meanwhile, Splinter fights a few Batmen and sabotages the ship, before accidentally encountering Dregg and Mung

Splinter uses the transporter to beam Leonardo and Donatello out of the black hole, Leonardo destroys the controls, which means that the ship will be sucked into the black hole. They manage to escape through the portal to the lair, where April greets them, just before the Dreggnaught is sucked into the black hole and destroyed. 

Donatello repairs the portal, only for a giant blue hand to reach through. Leonardo destroys the controls and shuts it off, and Donatello promises not to turn it on again.
