In the upcoming Batman #12, set for release on August 5, 2026, DC Comics introduces a new group of six assassins, echoing Spider-Man’s Sinister Six. The main cover showcases five of the six killers, including a woman with horned heels and a skull face, a muscular man, and a smaller figure with wild hair holding a beaker. The sixth assassin remains a mystery, adding intrigue to the storyline. The solicitation teases a dramatic narrative where these deadly killers invade Gotham City, prompting Batman to uncover the mastermind behind their arrival. This issue will also feature a significant development with the introduction of a new ally for Batman, potentially a new butler character, as he prepares for the Batman: Bad Seeds Poison Ivy event. With the promise of action and worldbuilding, Batman #12 is shaping up to be a pivotal installment in the series.
