professor Knock

Professor Knock made his entrance into the rich, shadow-drenched world of Dylan Dog in 1997, brought to life by the legendary Tiziano Sclavi and artist Bruno Brindisi in what was already one of Italy's most beloved horror comics. A figure who keeps genuinely remarkable company — sharing pages with Dylan Dog himself, the sardonic Groucho, the formidable Xabaras, and the brooding Ispettore Bloch — Professor Knock occupies a corner of the Sergio Bonelli Editore universe that rewards dedicated readers. With appearances stretching across nearly three decades into 2025, including turns in the prestige Dylan Dog Color Fest, this is a character whose staying power in one of European comics' great ongoing sagas makes him well worth seeking out for any serious collector of the genre.
