Action Comics Annual # 10 Adam Kubert / Joe Kubert Cover

Story 2: "The Many Deaths of Superman"

Luthor imagines what it would take to kill Superman (red sun solar fire, magic, brutal force, or kryptonite), as he's walking through a jungle looking for and finding a kryptonite meteor.

Story 3: "Who Is Clark Kent's Big Brother?"

Young Clark Kent tries to stop a rocket from crashing. Out steps a floating boy, speaking Kryptonese, and then English. He said "Son of Jor-El," but doesn't remember anything. Clark takes him home, and the boy sees the S shield, and recognizes it as the symbol of the house of El. He doesn't remember his name, so they make one up for him: Mon-El. They both operate under cover for a while, but Mon-El starts dreaming in a weird language, and saying "You don't belong here." So together they decide to test his Kryptonian heritage by exposing him to Kryptonite. Clark takes a lead box out of the safe, but before he can open the Kryptonite, Mon-El collapses, and regains his memory, remembering he was Lar Gand. He remembers being a seeker on Daxam, and researching data from Krypton's destruction. A rocket that left just before had a message; of which all that could be made out was "Son of Jor-El." Lar decided to follow the path of that rocket, to see if any Kryptonian artifacts could be found, but when he approached Earth's solar system, a sunspot disrupted his ship, so that he crashed. Now he realizes he is dying, as lead is toxic to his people. They try to figure out what to do, when Mon-El spots the phantom zone projector, and asks to be put in the zone. Clark does so, vowing to find a cure one day.

Story 4: "Mystery Under the Blue Sun"

Several Hawkmen and Hawkwomen from Thanagar are investigating the loss of several police cruisers, and find them wrecked in the vicinity of a cubical planet. Bizarros appear, trash this cruiser too, and return to the Bizarro World.

Story 6: "The Criminals of Krypton"

Zod, Non, and Ursa are being sentenced to the Phantom Zone by the Kryptonian Council. Flashback to an earlier time. Non, Jor-El's former teacher, is reviewing his findings about the planet's internal activities, and agrees that Krypton will explode within 90 days. But the General Zod, head of the Military Defense, interrupts and has them arrested (by Ursa). Non and Jor-El are warned not to discuss the heresy, and released. Jor-El starts working on a rocketship, but Non appeals to the people of Krypton instead, with Zod and Ursa observing. Zod starts to believe what Non is saying. But Non gets abducted, and lobotomized. Zod is outraged, and goes to Jor-El to have him join them in revolt. Jor-El cannot, as the council is needed to take quick action. Zod, Ursa, and Non try to take control anyway, but are defeated. Jor-El is made to be their jailer, and now is forced to exile them to the Phantom Zone.

Story 8: "The Deadliest Forms of Kyptonite"

Luthor talks about various kinds of kryptonite, imagining the effects of some of them. He ends up upgrading Metallo with all four kinds (green, red, blue, and gold) in preparation of starting a Revenge Squad.
