Venerdì 12 (Friday 12) is a comic strip series created by Italian author Leo Ortolani. It tells the story of Aldo, a man who becomes an hideous monster after being dumped by his girlfriend Bedelia. A cornerstone of the series is Giuda (Judas), Aldo's evil servant. Venerdì 12 started as a series of the comic magazine L'isola che non c'è and continued on the Rat-Man Collection, where it was also completed.
