Teenage Mutant Ninja Turtles: After befriending the once-human creatures in an abandoned underground Foot Genetics Lab, the Turtles join them on a journey deeper into the earth, where they come upon the ruins of a once-great subterranean city. When the Turtles and Creatures start vanishing one by one, only Michelangelo is left — and he finally finds the perpetrator — the city's lone surviving Entity. Though the Entity initially appears benevolent by restoring the creatures to their normal human selves, his true intentions become shockingly clear when he demands that they, and the Turtles, will remain in the city forever.
