Synopsis for the TV Cartoon Superman Meets His Match

A large chunk of Kryptonite collides with another meteor and hurtles down to earth. On the scene, Superman is weakened as the Kryptonite splashes into the ocean. Hitting the ocean floor, the Kryptonite cracks open revealing a strange green creature (modeled after the Creature from the Black Lagoon) who has the same powers as Superman. Unable to defeat the creature, Superman manages to knock it out long enough for him to fly it into space where he leaves it on a faraway planet.
