Bates, Swan and Blaisdel conclude the Faora story in Action 473 (July 1977).
Supergirl gets concerned when there is no word from Superman, despite Faora running wild in Metropolis. She finds a note in the Fortress, explaining that he has gone into the Phantom Zone, and other information that the reader is not privy to.
Faora gets into an argument with Steve Lombard, and is about to kill him when her greater scheme kicks in, reversing the Phantom Zone, releasing all its captives, while sending everyone on Earth into the Zone. Steve actually thinks he has died, until Jimmy Olsen explains the Zone to him. Batman and Green Lantern are also shown to now be phantoms, while Jax-Ur, General Zod, Kru-El and Professor Vakox enjoy their new freedom and solidity.
Faora takes dominance over the other Phantom Zone villains through her use of psychic bolts, but one Zone escapee is immune. It’s Superman, who figured out her bigger plan, and took precautions, including entering the Zone himself.
Superman is now stuck fighting against a number of similarly powered Kryptonians, and finds himself overpowered. Faora is about to kill him when the switch happens again. Bad timing! Superman rigged the projector to reverse Faora’s actions, sending the prisoners back into the Zone, and releasing the humans.
With one exception. The old man who still, after all this, believes Faora is his dead wife Katie. He gets to join her in the Zone.
From now on, Faora would be a regularly appearing Phantom Zone villain, almost always included when three or more are shown. But not the old man. We never find out what happened to him.
