Ghost-Maker / Clownhunter by James Tynion IV (Batman Vol. 3 #107-111)

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!
