High Quality Content by WIKIPEDIA articles! The Maggia is a fictional international crime syndicate that has appeared in various comic book series published by Marvel Comics. The organization exists in Marvel`s main shared universe, known as the Marvel Universe. Its structure is somewhat similar to the Mafia (which is itself almost never referred to in Marvel stories), but the Maggia differs in that it frequently hires supervillains and mad scientists to work for them. The characters Count Nefaria and his daughter Madame Masque have both been leaders of an important Maggia family. It first debuted in Avengers #13 (February 1965), and was created by Stan Lee and Don Heck.
