EARTH: Heterodyne Boys

The world of the Heterodyne Boys is one of black and white, where good and evil are strictly defined and the good guys always win. Bill and Barry Heterodyne are heroes in the early 20th century who routinely vanquish villains and monsters using their exceptional strength, intelligence and moral fiber.

The Heterodyne Boys traveled briefly to the interdimensional city of Cynosure, where they gave a sound thrashing to the regulars of Munden's Bar.

The brothers also appeared in a series of novels in the DC universe. It is mentioned that the novels were recounting the adventures of the actual DC counterparts of the Heterodyne Boys.

An alternate version of the Heterodyne Boys existed in the Girl Genius universe.

Herschel Clay, handyman at PS238, is a descendant of an alternate Agatha Clay (Heterodyne).
