Diabolik ( or ) is an Italian comic series created by sisters Angela and Luciana Giussani. One of the most popular series in the history of Italian comics, Diabolik was created in 1962 and consists of more than 900 volumes, and has led to the birth of the fumetti neri comic subgenre. The series is named after its protagonist, an anti-heroic thief, inspired by several previous pulp fiction characters from Italy and other countries. Its stories consist of monthly black-and-white, digest-sized volumes. The series takes place in the fictional town Clerville and stars the titular Diabolik, initially represented as a ruthless and cruel thief who does not hesitate to murder anyone in order to accomplish his deeds, aided by his partner and lover Eva Kant. Over time, the character evolved his personality, developing healthy roots and ethical principles such as honor, the sense of friendship and gratitude, and respect for noble souls, robbing and killing other criminals. Throughout his adventures, he is pursued mainly by the Inspector Ginko. The series sold more than 150 million copies worldwide, becoming one of the best-known and best-selling comics series from Europe. Live-action movie adaptations were made: Danger: Diabolik (1968) and a movie trilogy consisting in Diabolik (2021), Diabolik - Ginko Attacks! (2022) and an upcoming feature. Its success had also inspired a radio show, an animated television series, video games, novels, and countless parodies.

Co-creator Angela Giussani, who lived near Milano Cadorna railway station, thought of making comics in a format designed for travelling and carrying in one's pocket. To better understand the tastes of her potential readers, Angela made a survey of the market, from which she concluded that many commuters read mystery novels. Another version of the story claims that the very idea came from her finding a Fantomas novel abandoned in a train. Thus, was born the "Diabolik format" (a small 12 x book), which proved popular with other publications in the same genre. The pocketbook format contributed, in fact, to the success of the character. Plot Diabolik is a ruthless master thief. He typically steals from criminals (and has no issue with killing them if need be, but rarely, if ever, kills the innocent or the police), and has a set of lifelike masks which he uses to fool his opponents, assuming
