Ghost-Maker/Clownhunter by James Tynion IV

Ghost-Maker is the ultimate rival to Batman, trained by the same teachers to harness the power of the mind and body with one goal: become the ultimate weapon against crime! Unlike Batman, his approach is much deadlier, and he's about to go head-to-head with the Dark Knight! Also, Clownhunter's brutal mission to hunt down all the clowns from the Joker War continues! The untrained but focused vigilante stalks a boss-level clown, but his luck might be running out as he walks into an ambush set by Punchline! In a horrific parallel to his days at Gotham Academy, Clownhunter finds himself overwhelmed and outgunned…just the type of odds he likes! Collects Batman backups #107-111, Batman Secret Files: Clownhunter #1, Batman: The Joker War Zone #1, and stories from Batman 2022 Annual and Batman Annual #5.
