When the Leader detonated a gamma bomb in the town of Middletown, Arizona, later known as "Gammatown", only a few of its population of nearly 5000 survived, all mutated by gamma radiation: salesman Burt Horowitz, who gained the superhuman intellect of Omnibus was one of them.
When the Leader apparently died after trying to bring back Marlo Chandler to life, his position was taken over by Omnibus who, not content with the Freeholders' peaceful existence and apparently possessed by the Leader's surviving consciousness and mind control powers, manipulated Major Matt Talbot and others in the U.S. government in his own power-seeking plans.
