In issues #23-#25, Krang, who was banished to the toxic waste dump planet "Morbus" for exiled criminals, befriended two other criminals, Slash and Bellybomb. The group stole a spaceship and headed to Earth and happened to stop along the way at the same Eden World that Bebop and Rocksteady inhabited. Being bored of Paradise, Rocksteady and Bebop joined them on the trip back to Earth. However, rather than battle the turtles, the pair left Krang and the villains to fight the turtles and wandered the streets of New York City on their own. They robbed a clothing store to get clothes similar to their original attire, and a gun store for some guns. They then went to the zoo and blasted all the cages, setting all the animals free. Just as the turtles managed to defeat Krang (who had taken over Shredder's body), Rocksteady and Bebop arrived with guns and all the zoo animals, intending to take them back to the same Eden World. The turtles surrendered and let Bebop and Rocksteady escape in the spaceship with the animals. Leonardo asked them to take the defeated Krang and Bellybomb with them back to Morbus in Dimension X (Slash had already left the scene and was wandering the city). Bebop and Rocksteady did as asked and bid the Ninja Turtles farewell. The final panel of #25 shows the two mutants removing their clothes and going back to their simple life in the wilds of the Eden World.
