The dark origin of Batman's Future State adversary, Peacekeeper-01, will be explored in the upcoming one-shot Batman Secret Files: Peacekeeper-01. 

Batman Secret Files: Peacekeeper-01 will fill in the gaps from the Arkham Asylum guard readers met in March's Infinite Frontier #0 to become the sinister superhero hunter named Peacekeeper-01 who rules Gotham City in the near-future storyline 'Future State.'

Peacekeeper-01 is really Sean Mahoney, who following the attack on Arkham Asylum was enlisted for a new Gotham private security force. In one of his early missions however, he was dosed with the Scarecrow's Fear Toxin which led him into a tailspin that has him going rogue from his organization - and running wild in Gotham City.

But unless there's a twist in the story, we already know Peacekeeper-01 will takeover Gotham eventually as part of the organization known as the Magistrate. In the 'Future State' event, Peacekeeper-01 kills Batman - or so he thinks, as Bruce Wayne survived but decides to leave the mantle of Batman behind and instead become a vigilante known as the Dark Detective.

Future State's Peacekeeper-01 is known to have a deep and personal hatred for Batman, so the seeds of that may become evident during this Batman Secret Files: Peacekeeper-01 one-shot.

James Tynion IV and Ed Brisson are co-writing Batman Secret Files: Peacekeeper-01, with art by Joshua Hixson - who's also drawing the upcoming Batman/Fortnite: Foundation.
