Booster Gold came face-to-face with Darkseid on the planet of Apokolips while trying to save MISTER MIRACLE from the Cluster (see MANGA KHAN) and Darkseid's stormtroopers, the Para-Demons. Booster Gold would later join the Justice League in confronting Darkseid's hyper-fauna construct that had dominated Bruce Wayne.

Much later (from Booster Gold's point of view, but not necessarily Despero's), Booster works against the schemes of a time-displaced Desporo as a member of the TIME STEALERS.

Encounters with Booster Gold: 8

The Director of Death (often called simply "Director") was the mastermind behind the high-tech criminal organization 1000.

When Booster Gold foiled Senator Ballard's plans to become President of the United States (see CHILLER), the Director turned all of the resources of the 1000 into destroying the hero. In essence, the Director was Booster Gold's original arch-nemesis. The Director was often accompanied by an unnamed android that responded to his commands telepathically.

The Director employed a number of agents, including Jan in the Metropolis Athletic Club, in an attempt to destroy Booster Gold. Senator Ballard's aide Myron launched a tax evasion crusade against Booster Gold. The armored Blackguard (Richard Hertz) and psychic Mindancer were hired by the 1000 to defeat Booster Gold in combat. The 1000 freed Clarence Schiffel from prison so that he could don his Shockwave armor and assault Booster Gold's headquarters, REILLEAU TOWERS. Doctor Shocker hacked into the programming of SKEETS to turn Booster Gold's robot sidekick against him.

First Meeting with Booster Gold: Justice League America #69, 1992

Encounters with Booster Gold: 12

The creature they call Doomsday is a bio-engineered creature filled only with madness and hatred, especially of all things Kryptonian in nature. The name "Doomsday" frequently used to refer to the mute monster was coined by Booster Gold.

Booster Gold and the JUSTICE LEAGUE intercepted Doomsday on its way toward Metropolis. Despite the combined power of the League, Doomsday's progress was barely even slowed. Several Leaguers, including Booster Gold and most notably SUPERMAN, suffered terrible injuries and loss of powers that would take years to restore.

The second time Booster Gold battled Doomsday, Booster unintentionally destroyed the penthouse apartment of Alexandra Gianopoulos and was forced to rescue her from the monster.
