Morgan Edge was a black market collector.
Morgan Edge owned a private island that wasn't located on any map. He had recently acquired the criminal Clayface and siphoned him into biohazard canisters. He became a target of the Secret Society, because Grodd learned that Edge had Clayface captive.
Edge attempted to escape of the Secret Society's clutches by disguising himself as a chef, but was foiled when Grodd used his mental powers on him. When the team freed Clayface, Edge was killed by Killer Frost, presumably by being frozen to death.
Morgan Edge first appeared in Superman's Pal, Jimmy Olsen #133 in 1970, created by Jack Kirby. Edge was the CEO of Galaxy Communications (a.k.a Galaxy Broadcasting Program) which took over the Daily Planet and got Clark Kent and Lois Lane involved in TV news broadcasting as well as newspaper journalism. At one stage he appeared to be the leader of Intergang but this turned out to be a clone impersonating Edge.
When the DC world was radically changed following the Infinity Crisis of 1985, Edge became more evil and was genuinely connected to Intergang and Darkseid. Though he was incarcerated, he eventually escaped and became the founder of the Superman Revenge Squad.
