Justice League / Black Hammer

In this 2020 one-shot from Urban Comics, writer Jeff Lemire and artist Michael Walsh (with Julien Di Giacomo on scripting) bridge the worlds of the Justice League and the Black Hammer universe. The story brings together two distinct superhero mythologies, exploring how their heroes might interact when confronted by a shared cosmic threat. A concise, imaginative crossover that showcases Lemire's knack for character-driven storytelling within a single, self-contained issue.
