Comics Heroes and Villians: Lex Luthor Traditional Cache

The character was originally depicted as a mad scientist who, in the vein of pulp novels, wreaks havoc on the world with his futuristic weaponry. In his earliest appearances, Luthor is shown with a full head of red hair; despite this, the character later became hairless as the result of an artist's mistake. A 1960 story by Jerry Siegel expanded upon Luthor's origin and motivations, revealing him to be a childhood friend of Superman’s, who lost his hair when a fire destroyed his laboratory; Luthor vowed revenge.
