Hellblazer

John Constantine, Hellblazer is an American contemporary horror comic-book series published by DC Comics since January 1988, and subsequently by its Vertigo imprint since March 1993, when the imprint was introduced. Its central character is the streetwise English sorcerer and con man John Constantine, who was created by Alan Moore and Stephen R. Bissette, and first appeared as a supporting character in Swamp Thing (vol. 2) #37 (June 1985), during that creative team's run on that title. Hellblazer was released as launch title for Vertigo in March 1993, becoming the imprint's longest-running series and the only launch title to continue its run into the new century. In 2013, the series concluded with issue 300, and was replaced by Constantine, which returned the character to the mainstream DC Universe. The original series was revived in November 2019 for twenty-four issues as part of The Sandman Universe line of comics, under the DC Black Label brand. Well known for its extremely pessimistic tone and social/political commentary, the series has spawned a film adaptation, television show, novels, and multiple spin-offs and crossovers.

The series was the longest-running and one of the most successful titles of DC's Vertigo imprint, and was the stepping stone for many British writers. Notable writers who have contributed to the series include Jamie Delano, Garth Ennis, Eddie Campbell, Paul Jenkins, Warren Ellis, Grant Morrison, Neil Gaiman, Brian Azzarello, Mike Carey, Denise Mina, Andy Diggle, and Peter Milligan. Hellblazer was one of the first modern occult detective fiction works and heavily influenced the genre to come.
