Simon Hurt
Dr. Simon Hurt, commonly known simply as Doctor Hurt, is a fictional character from the DC Comics universe. Hurt was retro-actively revived in 2008 by writer Grant Morrison after first appearing as an unnamed character in Batman #156 (June 1963).
Development info
Visually, Doctor Hurt is based on an unnamed scientist who first appeared in Batman #156 (June 1963), in a story titled "Robin Dies at Dawn". In that story Batman participated in an experiment for NASA that caused him to hallucinate that Robin (Dick Grayson) was in constant danger; the story itself is referenced many times in Morrison's run on Batman. The character made behind-the-scenes appearances throughout Morrison's run before actually appearing fully in the first chapter of "Batman R.I.P."
The character was first called "Doctor Simon Hurt" in Batman #674. He is a brilliant psychologist whose true identity and nature is an enigma; over the course of Morrison's run he has been strongly implied at times to be the Devil, the demon Barbatos, a supernaturally-empowered ancestor of Bruce Wayne, Bruce Wayne's long-lost evil twin, Bruce Wayne's father, an instrument of Darkseid, and perhaps even Darkseid himself. Hurt is dedicated to completely destroying Batman in body, mind, and soul, and replacing him with a corrupted, evil counterpart.
