"Corporate Raiders from Dimension X" is an episode of the 1987 Teenage Mutant Ninja Turtles cartoon series.

Plot Synopsis

The Turtles listen to April's newest broadcast, which reveals that men in business suits have kidnapped high ranking corporate executives, and the remaining execs are threatening to leave. Leonardo wonders if they should help, but Splinter, Raphael and Donatello all think that this is not their kind of crime.

However, the latest executive kidnapped works for a massive baking company that is the nation's biggest supplier of pizza crust dough, and a global pizza shortage is expected due to disruption of company operations. Taking this very personally, the Turtles decide that they're going to investigate.

They stake out another massive corporation that is due to be attacked, and see suspicious business-suited men with laser guns. Leonardo manages to get a briefcase away from them, and finds it full of stuff from the conglomerate Octopus Inc.

Unfortunately, they don't have much of a chance to infiltrate the conglomerate, given how they look. Michelangelo suggests that they get Casey Jones to infiltrate the place and find information on them. They lure Casey to the park with a fake personal ad claiming that they are going to rob a candy machine. He promptly attacks the Turtles, causing more damage to the machines than they would have. After Raphael subdues him, they explain what they want him to do.

Casey applies for a job at Octopus Inc., where his "ruthless violent attitude" and "take-charge aggressiveness" is immediately welcomed. He's brought into a new employee training program that hypnotically turns people into mindless slaves. Casey tries to escape, but is held back in his chair.

While the Turtles are anxiously waiting, more laser-toting businessmen arrive to take over a small corporation. As Leonardo, Michelangelo and Raphael are driven to seek cover, Donatello whips out the Retro-Catapult to fling garbage at them... but misses and hits his brothers instead. Donatello hits them with a bucket of water, which leaves the men confused and unable to remember what happened.

The Turtles infiltrate the building disguised as repairmen, and find Casey still being brainwashed. Donatello squirts Casey with water, breaking him out of it, and the human destroys the hypnotic equipment.

They accidentally overhear a board meeting where a man declares that the Octopus Stadium will be filled with all the brainwashed employees later that day, for the Grand Arising, after which they will take over the world. They keep squirting the brainwashed men, but soon discover someone has cut off the water supply to the entire building, leaving them no choice but to flee when the water runs out. With this, the Turtles realize that someone who's not brainwashed is pulling the strings.

In the office of the president of the company, they find Shredder, Rocksteady and Bebop. After a massive fight, Casey and the Turtles are tied up and thrown in with an old man who has also been tied and gagged.

Leonardo manages to free himself using a hacksaw, and frees the others. They find that the old man is the president of Octopus Inc, Octavius Ogilvy; his hearing aid is broken, which made him immune to the hypnotic brainwashing. He shows them the blueprints for the Octopus Stadium, which reveals to the Turtles that the "Grand Arising" is to raise the Technodrome to the surface.

At the stadium, Donatello tinkers with the hydraulics under the stadium. But instead of the Technodrome, a vast octopus-shaped device arises from the ground and sprays the audience with water, causing all the gathered executives to wake up from their hypnotic spell.

Shredder, Bebop and Rocksteady all flee the stadium, and the Turtles are congratulated by Ogilvy, who vows to make the world a better place. Raphael opines that "it may not be a realistic ending, but it is a happy one!"
