Superboy #91

Superboy stumbles into a strange planet where android duplicates of Smallville’s townsfolk are locked in a reenactment of the Civil War. When he tries to save Clark Brent from a firing squad and later General Kane, Private Rothul, and Nurse Bertha, he realizes the conflict is far from real—only a game played by two ancient alien generals.

When "Sparkle" Smith blackmails Jim Marsh into posing as Superboy to swindle the people of Bigville, the real Superboy must outwit the impostor and his henchmen without exposing Jim’s father, Lionel Marsh’s past. With Krypto by his side and the town watching, Superboy turns the con around in a clever twist that leaves the frauds caught and the truth intact.

When a fire-breathing metal-eater from space leaves Superboy and Krypto ravenously hungry—eating everything from park benches to paint and even iodine—the Kent family in Smallville must help them figure out what’s behind the strange craving. Superboy soon discovers the hunger is tied to green and red objects, leading him and Krypto to set off toward distant moons of those colors to satisfy their unusual needs.
