Führer Hell Saturn revealed himself at the beginning of Black Magma's campaign to conquer the world, giving a vision to the general assembly of the United Nations after several Guardians of World Peace planes were shot down at the North Pole to declare their existence and intent. Through this, the UN activate the GWP's Sun Vulcan program to deal with the machine empire.

Commanding Black Magma from Iron Claw Castle, Hell Saturn mainly appeared to direct the organization, commanding his Zero Girls and Machinemen in combat, directing the development of Dark Q spies and Mongers for his intent of causing global chaos and disruption. Aside from global chaos and maintaining his group, he likewise tended to have a knack for searching for hidden treasures that would allow for the organization to gain a monetary supply they can control. His battles appear to be fought for the sake of the "Black Sun God", a supernatural being of the black sun symbolized by a statue within a chamber of his castle; but in truth it is merely a symbol for his real boss: The Omnipotent God, who was hidden away deeper within the castle and who was the true mastermind giving him orders for his mission.
