2nd Feature: (The first Adventure issue to feature a story of the Legion of Super Heroes). Saturn Girl, Cosmic Boy, Lightning Lad and Sun Boy are having trouble with their powers. They request Superboy's help. He joins them from the past where they are attacked by a masked villain. They request additional help from Mon-El, who's still trapped in the Phantom Zone.
The Legion is about to be exiled from Earth since they can't control their powers, and a man in a lead mask who calls himself Urthlo claims he is responsible. When Mon-El is summoned from the Phantom Zone, Saturn Girl gives him a potion which cures him of lead poisoning, so he can defeat Urthlo, who turns out to be a robot with the face of Lex Luthor. Back in Superboy's time, Luthor built the robot and equipped it with a super-power nullifier, then sent it into the future in an attempt to destroy the Legion.
