Kriminal is an English master thief, Anthony Logan, who dresses in black and yellow costume with a fearsome skull face for his adventures. The character was directly inspired by the contemporary Diabolik, with whom he shares the ability to use masks that allow him to assume any identity. In the earliest adventures, Kriminal was a near sadistic killer fighting for revenge against the criminals who had pushed his father to commit suicide. Having also lost his mother and sister, Logan spent his youth in a reformatory, from which he managed to escape, intent to pursue vengeance. Kriminal has a female companion, Lola Hudson whom he married and with whom he had a child, Max. He also has a love-hate relationship with Gloria, who was once the wife of Scotland Yard Inspector Patrick Milton, his main enemy. Gradually over time, Kriminal's most extreme villainous features were toned down, and in the later stories he assumed more positive and heroic connotations. The series was also notable as one of the first to employ continuity in Italian comic books, as any new story would begin exactly at the point the previous had ended, and the characters' lives continually evolved. Logan himself married and had a child, who soon died. The series ended in November 1974, after 419 episodes.
Censorship
Due to the violence and the proto-erotic scenes in the comic book, Bunker and Raviola had problems with Italian censorship. Bunker was prosecuted several times, but never condemned. The panels depicting semi-nude girls were often censored by the publisher itself.
Crossovers
In the episode #90, "Quello che non ti aspetti", Kriminal meets Satanik: this is the first example of crossover in Italian comics. The character is also featured in Alan Ford #150, also by Magnus & Bunker.
Cinema
Kriminal has been adapted for the big screen several times. The first film, simply titled Kriminal, was released in 1966 by Umberto Lenzi, starring Dutch actor Glenn Saxson in the lead role. The skeleton costume was slightly altered. A sequel, Il marchio di Kriminal directed by Fernando Cerchio, followed in the summer of 1968
