Superboy Season 1 Episode 9

The Alien Solution

A strange cloud-like alien who can take over others bodies comes to earth hoping to steal Superboy's body so he can add it to his collection of warriors. Knowing Superboy always comes to Lana's rescue, he puts her in danger and lures Superboy into the open. After Lana is almost killed by the alien's warrior body, Superboy agrees to do what the alien wants. He follow the alien to its ship, and destroys the alien's collection of warrior bodies. He then traps the alien in a canister, and hides the canister in a cryogenics lab on the college campus.
