Garth Ennis has been writing comics since 1989. His credits include Preacher, Hitman, The Boys and the war series Battlefields and War Story, as well as successful runs on The Punisher and Fury for Marvel Comics. Originally from Belfast, Northern Ireland, Ennis now resides in New York City with his wife, Ruth.

The late artist Steve Dillon had his first paying work at age 16 for the UK-based Hulk Weekly magazine. Like many of his British contemporaries, Dillon honed his skills on the legendary 2000AD. In 1993, Dillon joined writer Garth Ennis on DC/Vertigo's Hellblazer. Their work earned overwhelming praise from the title's devoted fan base and led to a second collaboration on Preacher, which earned an "A" grade from Entertainment Weekly and was later turned into a TV series on AMC. After Preacher's 66-issue run, Dillon again teamed with Ennis on a revival of Marvel's classic antihero, Punisher. Dillon later illustrated Daniel Way's Wolverine: Origins, Ennis' Punisher: War Zone, Mark Millar's Ultimate Avengers and Jason Aaron's Punisher MAX. Dillon again drew Frank Castle for Marvel NOW! in the relaunched Thunderbolts and later in All-New, All-Different Marvel's The Punisher.
