History

  A "fear parasite" from another dimension who made several members of the JLA experience their greatesr fears and temporarily quit their super-hero careers. Nekron lived and grew stronger from the fear of death he caused in the heroes and other people. However, he had to use physical force on Green Lantern who was allegedly born without fear. Nekron was finally defeated when Aquaman and the Atom used the Green Lantern's Power Ring to augment the fear of Superman – thus "overloading" Nekron with "super-fear". Nekron shrunk to the size of a bug and was imprisoned in the JLA satellite. His current whereabouts are unknown.
