such as Hellboy, Supernatural, Grimm, The Originals, and The Dresden Files have been influenced by it, and many imitators of both the series and its character flourished such as Criminal Macabre, Gravel, Planetary, and others. Its elements and style have been used countless of times in other works and many analogues of the cynical protagonist John Constantine have appeared. Other examples of occult detectives in comic books include Doctor Spektor from Gold Key Comics, Hellboy from the Dark Horse series of same name, Dylan Dog from the Sergio Bonelli Editore series, Nightlinger by Steven Philip Jones and published by Caliber Comics; certain elements and characters in The Goon; Martin Hel, a character created by Robin Wood; the Joe Golem series; and Witchblade from Top Cow Productions. Two Hellblazer writers have gone on to write their own occult detective characters: Sebastian O also at Vertigo by Grant Morrison and Warren Ellis' Gravel from Avatar Press. 2000 AD has featured a number over the years in their own eponymous series: Bix Barton, Devlin Waugh, Ampney Crucis Investigates and Dandridge. The occult detective team of Syd Deadlocke and Doc Martin, featured in Pulse of Darkness and other comics by Chris G.C. Sequeira, also fits into this genre. There is also the comic book series Ruse, once owned by CrossGen and now by Marvel Comics. Examples in manga and anime include Majin Tantei Nōgami Neuro, Mushishi, YuYu Hakusho, Ghost Hunt, Mononoke, Death Note, Ghosts at School, Dream Hunter Rem, Bakemonogatari and Nightwalker: The Midnight Detective.
