Tales of the Legion of Super-Heroes in "The Face Behind the Lead Mask"
*During a routine meeting, the Legionnaires suddenly begin losing control over their powers. Even Superboy, whom they have summoned to the future, cannot discover the cause of their problem. After the World-Wide Police threaten to banish them from Earth, a lead-masked villain calling himself "Urthlo" appears and takes credit for the predicament.
Because Urthlo possesses a device that controls their powers, the heroes find themselves unable to stop him, until Saturn Girl and Superboy release Mon-El from the Phantom Zone, where he has been for 1000 years. After she provides him with Serum XY-4, a temporary lead-poisoning antidote, Mon-El defeats Urthlo, who turns out to be a robot sent into the future from Superboy's time by a vengeful Lex Luthor.
After the battle, Mon-El must be returned to the Zone, but only after being voted into the Legion. *Source: The Official Legion of Super-Heroes Index #2 - Published by ICG.
