Theodore B. Carrigan is a carnival mystic who turns to crime, basing his robberies on horoscopes. In his first outing, he is apprehended by Batman, Robin and Superman. Later, he steals a dozen coins from Atlantis, each bearing a Zodiac symbol, which bestow him with various powers. Once again, Batman and Superman thwart his plans. Still later, he allies himself with Madame Zodiac to obtain a different set of Zodiac coins, but the two of them are defeated by Batman, Superman, and Zatanna.
