"Teenagers From Dimension X" is the eleventh episode of the second season (1988) of the 1987 Teenage Mutant Ninja Turtles cartoon series. It was written by Michael Reaves. It originally aired on December 10, 1988.
In Dimension X, the three Neutrinos spot the Technodrome and decide to sneak into a cargo bay. They intercept a message from Krang to Shredder, preparing to send through the Mental Neutralizer so that Shredder can turn the Turtles into "mindless zombies." The Neutrinos open their own portal to Earth so that they can save the Turtles.
To make the Turtles find them, the Neutrinos buzz the Channel 6 building. April tips off the Turtles, but also accidentally lets Shredder know where the Neutrinos are. Before the Turtles can lead their friends to safety, Rocksteady and Bebop capture them. The Turtles attempt to catch up, but an updraft causes the glider to crash.
Michelangelo is extremely anxious about the situation, but his attempts to meditate are wrecked when Donatello unveils his latest invention, the Cheapskate, a motorized skateboard.
Meanwhile, Shredder demands the trans-dimensional device the Neutrinos have, but it's part of the Starmobile... which Rocksteady and Bebop left behind. As a result, it was towed. Just then the Turtles burst into Shredder's amusement-park hideout and rescue the Neutrinos.
The Neutrinos explain Krang and Shredder's plan to turn them into mindless zombies, and how the Starmobile can neutralize the Mental Neutralizer with a flip of the switch on their dashboard. However, the trilithium crystal that powers their Star Mobile is cracked, and can only be replaced in Dimension X. Fortunately, Leonardo knows the location of a particle accelerator that can repair the crystal, and though it seems that the crystal is about to explode, they manage to repair it.
Unfortunately, the power surge was enough for Krang to detect and locate them. Shredder and his goons appear just as the Turtles and Neutrinos are about to escape, and stun them all. Shredder takes the newly-repaired Starmobile and the unconscious Turtles, leaving the Neutrinos on the sidewalk.
Fortunately, April rescues the Neutrinos, having gotten a distress signal from Leonardo. They run afoul of a gang called the Cyberpunks, but manage to escape into the sewers.
Meanwhile, the Turtles wake up bound in the Starmobile, and quickly placed inside the Mental Neutralizer. But as Shredder tries to open a portal, the Starmobile's security features cause him to be frozen in place. The Turtles slip out of the Neutralizer and manage to trick Rocksteady and Bebop into shooting them free.
The Cyberpunks arrive at the location and chase Shredder, Bebop and Rocksteady into a collapsing building, while April, the Neutrinos and the Turtles all escape in the Starmobile. The Neutrinos say their goodbyes, and Michelangelo gives them a pizza, which burns their hands as they depart. Michelangelo is downcast, but cheers up when Raphael points out that no Kala means more pizza for him.
