“Black Hammer/Justice League: Hammer of Justice is a project that I still can't believe is actually real, even though I've written the whole series already,” Lemire said Wednesday in a statement. “Everyone who knows me and knows Black Hammer is aware of my love of the DC Universe. Getting this great opportunity to work with an artist like Michael Walsh to bring the Black Hammer and DC universes together for a special story was just too much fun. I'm incredibly excited about the story and think fans of both universes will enjoy reading it as much as Michael and I enjoyed creating it."

Lemire’s Black Hammer, created with artist Dean Ormston, debuted from Dark Horse Comics in 2016 and has since expanded to include a number of spinoff series including Sherlock Frankenstein and The Quantum Age, all with Lemire attached as writer or co-writer. The series, which won the Eisner Award for best new series in 2017, was optioned by Legendary Entertainment last year, with a view to adapting into a multi-project franchise spanning movies and television.

The first issue of Black Hammer/Justice League: Hammer of Justice is set to be released digitally and in comic book stores July 10.
