Golden Age Origin: 

Frost was a German saboteur who ingested a special pill which gave him ice powers. When Blue Fire attempts to stop him, Frost tries to shoot Blue Fire, but the bullets phase through him. Fire then tries to punch Frost, but he can not hit him while intangible. The two reach a stalemate and with Blue Fire's powers about to run out he left his foe. When he brought the police to capture Frost, the villain had escaped. Tanya Gerhst, a fellow German spy, and Frost were later confronted by Blue Fire at their hideout. Frost began to fight Fire, but lost control of his intangibility and plunged to the bottom floor of the building. Frost manages to escape capture by Blue Fire, but Fire stops him from freezing another ship.
