(Superman I #684) - Superman and the Science Police freed Parasite and the other criminals trapped in the Phantom Zone to return them to prison. Parasite took the opportunity to briefly pull Mon-El from the Phantom Zone to absorb some of his Daxamite power. Superman quickly handled Parasite, and he was briefly imprisoned, but the energy he'd absorbed made him strong enough to escape. Parasite was on the run and absorbed the life energy of a gas station attendant and patron. He reflected that the patron's attractive girlfriend would have been useful when he posed as Lois Lane to capture Lex Luthor's heart, and his thoughts were clearer because he'd retained the way Torval Freeman thought. He wanted to find Mon-El again, because with his power he could rule Metropolis.
