At the beginning of "Superman", Non is one of the three Kryptonian criminals, along with General Zod and Ursa, on trial for their attempted coup against the Kryptonian government. With Jor-El as their prosecutor, the three are found guilty and sentenced to be imprisoned in the Phantom Zone. They are cast into the Phantom Zone portal shortly before the planet Krypton is destroyed. Non, lacking the ability to speak, communicates only through occasional whines and moans as well as his penchant for wanton violence. Non's name is mentioned twice during the film "Superman II", once in the beginning by the unseen prosecutor during the trial recap and once by Ursa ("he's caged Non"); Jor-El's only reference to him is to proclaim that he is ""a mindless aberration, whose only means of expression are wanton violence and destruction."
