The Scarlet Widow was one of the few female master criminals faced by Superman on radio's The Adventures of Superman. A dangerous, greedy hag, described as gaunt and ugly, the Widow was often assisted by her Cockney henchman Sniggers. Her most significant act was the theft of Kryptonite from the Metropolis Museum, which she then split into four chunks. Unlike most of Superman's enemies, however, the pragmatic Widow had only profit rather than revenge in mind, by splitting the Kryptonite into chunks and auctioning it off to four of Superman's greatest (radio only) enemies: The Laugher, The Vulture, Papa Raush, and Der Teufel.
