A Zero Month crossover. The leader of a bunch of bounty hunting bandits tells his team about the origins of the Main Man Lobo. We get to see Lobo’s birth; how Lobo killed everyone on his home planet Czarnia; Lobo’s fights with Superman and Santa Claus; how he was recruited to join the L.E.G.I.O.N.; and how he can regenerate any damage. The group accidentally crosses Lobo, who hunts down the team and kills each one of them, with one exception. Unfortunately, the survivor accidentally tampers with the bomb Lobo has attached to his wrist.
