JLA Superpower is a perfect-bound one-shot released by DC Comics in 1999. It stars Mark Antaeus, a young hero who becomes a member of the Justice League. Over the course of the issue, we witness the rise and fall of a super-hero. This marks the DC Comics' debut for writer John Arcudi, who gained fame co-writing the various B.P.R.D.miniseries and one-shots for publisher Dark Horse with creator Mike Mignola. Arcudi would go on to write another JLA miniseries ( JLA: Destiny) before relaunching the Doom Patrol. The artwork for this one-shot was done by Scot Eaton and Ray Kryssing.
