Fanhunter is a bizarre "universe" created by the Spanish comic author Cels Piñol. The Fanhunter universe combines subcultural elements from comics, science fiction, role playing games, action films... with bizarre parody characters from the Spanish comics scene (comicbooks mailings, meetings, specialized libraries and stores...) acting as constant conspiratorial wink to its target audience.
Characters are mostly inspired in real-life people who are important for the Spanish comic-book and subculture community, and also in fictional characters easily referenced. Alejo Cuervo, for instance, is a real-life publisher who is in good terms with author Piñol, and the Fanhunters were initially a parody of DC Comics characters Manhunters.
