DC Finest: Superboy: The Superdog from Krypton #[nn]

When Mr. and Mrs. Lang are believed to have died in Africa, the Kents take in their daughter Lana—only to find themselves entangled in a mystery when two criminals mistake her for Superboy.

In "The Super-Dog from Krypton!", a rocket carrying a super-powered dog crashes in Smallville, accompanied by records that reveal he’s the puppy Jor-El once used to test his space rockets—making him a long-lost companion to baby Kal-El. Though thrilled to be reunited with his old friend, Superboy must keep Krypto from accidentally exposing his secret identity while the dog’s wild energy leads to a series of chaotic adventures.

When Superboy vanishes for a week, Professor Wilson constructs a robot duplicate to fill in—only for the real Superboy to return, disoriented and with no memory, after a strange encounter with a comet. Now, the boy hero and his mechanical twin must navigate a world where identity and trust are anything but certain.
