Underworld Unleashed

In 1998, DC Comics unleashed a one-shot by writer Mark Waid and artist Howard Porter that redefined the stakes of the DC Universe. The story sees a powerful demonic entity offering Earth's villains a chance to trade their souls for immense power, forcing heroes to confront the dark bargain. This single issue matters for its bold, high-concept premise and its enduring influence on how DC explores the moral complexities of its rogues' gallery.
