Chap 2. : "The Secret of Mon-El"

Although Superman would search in vain for a cure for years, Mon-El would eventually be released from the Phantom Zone permanently in the 30th century, and cured of his lead poisoning by a serum created by Saturn Girl and perfected by Brainiac 5. This story provides a clue to the element crucial to the serum’s long-term effects, Kryptonite, in a scene in which, in the presence of Kryptonite, Mon-El is unaffected by the proximity of lead.

This story is based in part on "Superman’s Big Brother" in the first story of Superman #80, which is the closest Earth-2 counterpart of this story.

Synopsis:
One evening outside Smallville, Superboy rescues an older teenager from an exploding rocketship. Although the boy cannot remember his origin, his super-powers, a medallion, and a note written by Superboy’s father Jor-El convince them both that he is Superboy’s older brother. Christened "Mon-El" after the day he arrived (Monday), he is adopted by the Kents, and takes the secret identity of Bob Cobb, brush salesman.

One night, Superboy notices that Mon-El’s belt buckle is made of non-Kryptonian metal. Playing a hunch, he exposes a sleeping Mon-El to Kryptonite and determines that, whoever this stranger is, he is not from Krypton. When the two of them confront a gang of criminals who are catapulting lead boulders on Smallville, Mon-El collapses, the crooks escape, and Superboy is convinced that his new friend is in league with them.

Intent on exposing this ruse, he confiscates the lead boulders and paints them to look like Green Kryptonite, and then arranges a fake meteor shower. Feigning agony, he watches Mon-El weaken; then he stands, accuses him of lying, and shows him the "evidence". However, the exposure to lead has returned Mon-El’s memory, and he explains that he is a traveller from a Krypton-like world, Daxam, who landed on Krypton and met Jor-El and Lara shortly before the planet exploded. Moreover, he says, a Daxamite is doomed once exposed to lead.

Fortunately, Superboy is able to save Mon-El’s life by projecting him into the Phantom Zone, and vows someday to find a way to free him.
