Justice League Dark is a comic book series published by DC Comics, debuting in September 2011 as part of the New 52 relaunch. Created by writer Peter Milligan and artist Mikel Janín, it introduced a supernatural spin-off team from the main Justice League, focusing on occult experts and magical heroes who handle threats too arcane for conventional superheroes. The core roster includes John Constantine, Zatanna, Deadman, Madame Xanadu, and Swamp Thing, with occasional involvement from characters like Batman and Wonder Woman.
The series blends horror, mystery, and superhero action, exploring themes of magic, the occult, and the blurred lines between good and evil. Milligan's run delved into psychological horror and team dynamics strained by Constantine's cynical leadership, while subsequent writers like Jeff Lemire expanded the lore with epic battles against entities like the Others and the mysterious House of Mystery. It ran for 40 issues until 2015, spawning spin-offs and cementing its place in DC's Vertigo-influenced supernatural corner.
Justice League Dark has had a lasting impact, influencing DC's broader multiverse narratives and inspiring merchandise, video games, and fan interest in its gritty, mature take on the superhero genre.
