Mon-El
Mon-El
Real name: Lar Gand.
Mon-El first arrived on Earth suffering from amnesia during Superboy's time in Smallville. Mistakenly believing he was from Krypton, Mon-El was "Superboy's Big Brother" (SB No. 89, Feb 1961).
However, with his memory restored, Superboy and Mon-El learn he is actually a native of the planet Daxam, a Krypton-like world, which gives Mon-El super powers under a yellow sun. A Daxamite's one weakness is lead, which is abundant on Earth. Unlike exposure to Kryptonite in Superboy's case, lead exposure to a Daxamite is fatal. To save his friend's life, Superboy projects Mon-El into the Phantom Zone.
Mon-El remains trapped in that twilight dimension for over a thousand years until Brainiac 5 of the Legion of Super-Heroes concocts a final antidote for Mon-El's lead poisioning.
Fully cured, Mon-El becomes a member of that heroic teen brigade of the future, the Legion of Super-Heroes.
When Superman visits the Adult Legion of Super-Heroes, he learns that Mon-El was roaming the spaceways as an explorer, clearing the way for intergalactic settlers.
