Justice League Dark, or JLD, is a superhero team appearing in American comic books published by DC Comics. The team made their debut in Justice League Dark #1. The team features some of the more supernatural characters in the DC Universe, handling mystical threats and situations deemed outside the scope of the traditional Justice League. Similarly to the Justice League title, the team features well-known characters such as John Constantine, Zatanna, Doctor Fate, and Wonder Woman while also bringing exposure to lesser-known supernatural characters. The team has starred in an eponymous animated film and in Justice League Dark: Apokolips War.
