Thundarr the Barbarian

After saving a old man named Tyron from the rat-like Groundlings, Thundarr, Ariel and Ookla learns that the Groundlings are in search of The Black Pearl, which the evil wizard Gemini fears it's power. Thundarr, Ariel and Ookla agrees to deliver the Black Pearl to the village of Manhat (the ruins of Manhattan). But Ariel is captured and taken to Gemini's tower and Gemini demands that Thundarr and Ookla gives him the Black Pearl or Ariel will die.

Thundarr, Princess Ariel, and Ookla encounter a train carrying Death Flowers (whose pollen can hypnotise both humans and Moks) being transported by the Carocs (a race of crocodile people) to a wizard.

The evil wizard Mindok lost his body in the Great Cataclysm 2000 years earlier, although his brain survived. He, General Zoa, and Zoa's minions seek out cryogenically frozen 20th-century scientists called "Ice People" in a plot to build Mindok a new body for his brain.
