Part 2: "The Revenge of Superman"

Synopsis:
An alien race contacts Batman and brings him to an alien world under the pretense of aiding a great emergency. When he arrives on the alien world, Batman is hypnotized by the aliens into becoming a cruel prison warden. His prisoners are the innocent heroes of many worlds.

Batman then tricks Superman into coming to the planet. The aliens use a filter to cause the sun's rays to become red, removing nearly all of Superman's powers. Superman then becomes a prisoner.

With his last remaining bit of super powers, Superman manages to restore the powers of some of the other prisoners. They break free, help Superman fake his powers, and overthrow Batman. Superman then puts Batman to work as a prisoner.

The aliens discover Superman's escape and return to the planet to investigate. They discover that Superman does not have his powers. However, Superman has helped Batman break the hypnosis. While the aliens are investigating Superman, Batman destroys the red sun filter with the aliens' own ship. Superman's powers are restored. He frees the wrongly imprisoned heroes and ends the aliens' plans to conquer the galaxy.
