The Adventures of Superboy (1988)

Revenge of the Alien (2) (1x14)

:

Now controlling Pa Kent, the alien makes his move to get revenge. He kinaps Lana and holds her hostage on a rooftop near Shuster University. Clark sees his father on the news with Lana and realizes something is wrong. When Lieutenant Harris tells Superboy that the cryogenics lab was robbed the night before, Superboy realizes who he is dealing with. He finds Pa Kent, and tells the alien that he will allow it to enter his body as long as he lets Pa Kent go. The alien agrees and Superboy takes the alien to Professor Peterson's lab. After the alien enters his body, Superboy activates a kryptonite ray in the lab. The kryptonite begins to kill Superboy and the alien inside is in agony. Superboy realizes he is dying. Pa Kent helps him move into a cryogenic freezer. Inside, the alien exits Superboy's body not realizing where he is. Once he goes into the cold air, his gaseous body freezes and becomes solid. Then it breaks apart into hundreds of pieces.
