Some time ago, Bruce Wayne took part in an isolation experiment overseen by Dr. Simon Hurt in which the psychiatrist gave Bruce the post-hypnotic phrase ""Zur-En-Arrh."" When heard by Bruce years later, this trigger phrase shatters his mind and leaves him wandering Gotham City in a daze. Always ready with a back-up plan, though, Batman had previously developed a persona within himself-a Batman without Bruce Wayne-and stitches together a new Batsuit, calling himself the Batman of Zur-En-Arrh!
