Duncan Pramble was once a research assistant to an archaeologist named Doctor Charles Ferris. Many years ago, Pramble accompanied Doctor Ferris as well as the Challengers of the Unknown on an expedition to an island known as Ruins. Within the ruins of the island, Pramble discovered an ancient elixir known as "Liquid Light." According to nearby hieroglyphs, consumption of this elixir granted the imbiber additional lives. With each new life, the partaker would also receive a new power. Pramble greedily drank the chemical fluid and, as promised, gained extraordinary new powers. He decided to use his new powers to become a criminal and turned his attention towards defeating the Challengers.
