Trivia / Diabolik

• Defictionalization: In 2012 the Italian knife-maker Maserin produced a reproduction of Diabolik's iconic knife as part of the celebration for the fifty years of publication. Fans have verified and confirmed it's a good throwing knife.
• Fountain of Expies: Italian comic books of the late sixties were invaded by murder-prone Criminals with a K in the name (Satanik, Kriminal, and a few others). They were out of publication before the end of the seventies, with the exception of the titular Paperinik New Adventures and Cattivik.
• Life Imitates Art: Once in a while, one of Diabolik's gadgets is invented in Real Life. For example, Diabolik used an automotive navigation system (not linked with a satellite and limited to a single road, but still working) in the story "The Heart of Fire" published in 1967.
• No Export for You/Keep Circulating the Tapes: The animated series was produced by Saban Entertainment, and never made it to the US; it only aired on the international Fox Kids networks (which have since become Disney XD). Hence, it's never received a home media release, as Disney routinely neglects the Fox Kids/Saban archive programs they own.
• Reclusive Artist: Up to eleven with Zarcone (also known as "The German"), the mysterious artist who drew "The King of Terror" and disappeared right after delivering the pencilled art. Between that and Zarcone being a pen name (as it used to be the norm in Italy back then), nobody has any idea where he disappeared to, not even the private detective the Giussani sisters hired to track him down. Also, the fans didn't even know he existed for thirty years (most fans had read the first reprint, which had been redrawn by Luigi Marchesi, and those who had the original issue had only seen the name of the cover artist Brenno Fiumali and assumed he did the whole book), until the original creators revealed his name.
• The Shelf of Movie Languishment: Though the Saban cartoon was produced in 1997-98, it apparently didn't air until 2000.
• Uncredited Role: Abnormally for a Saban cartoon, the Toronto-based voice cast is uncredited completely, leaving people to speculate who voiced who.
