An early version of Justice League Dark is the most powerful version of the team ever. Today, no one questions the existence of a team comprised solely of magic users such as Zatanna and John Constatine, but in the mid-1990s, the concept was still unheard of–that is until 1995’s Underworld Unleashed: Abyss: Hell’s Sentinel #1. This special one-shot, which tied into the publisher’s Underworld Unleashed event, introduced a team of sorcerers and other supernatural characters 16 years before Justice League Dark made its debut. And this early version of the team was its most powerful incarnation as well.
