Boldman, Saviuk and Schaffenberger share the last in-continuity pre-Crisis Superman story in Action 582 (Aug. 86).
After having a number of vivid dreams about Jor-El and Lara, Superman discovers that there are two other, distinct, brain-waves in his head. He believes these two be the minds of his parents, somehow preserved within him.
He creates clone bodies for them, and is thrilled when the brain-waves transfer from his mind into the bodies, animating them and bringing his parents back to life. He provides them with human identities, and shows them around Metropolis, and Earth, while helping them adjust to their new powers.
Superman brings them to his Fortress of Solitude, but when he shows them the Phantom Zone viewer, he is surprised that the villains, General Zod, Jax-Ur, Professor Vakox and Faora, are cursing him, and not his father, the man who invented the Zone and sent many of them there.
And, indeed, his parents are not his real parents. How the Phantom Zone villains could tell is not clear, but once Superman suspects them, they drop the act and try to kill him. They put him in a rocket and fire him into space.
Superman escapes from the rocket, but spots a familiar ship orbiting Earth. It belongs to Rokk and Sorban, the compulsive gamblers from Ventura. Frequent guests in Superman’s own comic, and World’s Finest, back in the 60s, this is their first, and only, appearance in Action. They used some “free-floating” consciousnesses for Jor-El and Lara, but the bet at the core was whether Superman would be angry enough to kill the phonies, or not.
The story ends as Superman takes Rokk and Sorban to the “prison planet,” (Takron-Galtos?) Superman shows little concern about what the phony Jor-El and Lara are up to, loose on Earth, with all their powers. But the gamblers assure Superman that they will return to their non-corporeal state.
