Dr. Simon Hurt, commonly known simply as Doctor Hurt, is a fictional character from the DC Comics universe. First appearing as an unnamed character in Batman #156 (June 1963), the character was retroactively revived in 2008 by writer Grant Morrison and established as Thomas Wayne, a distant relative of Bruce Wayne and his father Thomas Wayne.

Visually, Doctor Hurt is based on an unnamed scientist who appears in Batman #156 (June 1963), in a story titled "Robin Dies at Dawn". The character made behind-the-scenes appearances throughout Morrison's run before 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. Has been implied to be the devil, the demon Barbatos, a supernaturally-empowered ancestor of Bruce Wayne, Bruce Wayne's long-lost twin brother, Bruce Wayne's father, an instrument of Darkseid, and Darkseid himself. Hurt is dedicated to destroying Batman in body, mind, and soul, and replacing him with an evil counterpart.

Doctor Hurt led both the Black Glove and the Club of Villains against Batman in "Batman R.I.P." Hurt was the main antagonist of Morrison's run on Batman titles from 2007 to 2011, appearing in Batman, The Return of Bruce Wayne, and Batman and Robin, as well as behind-the-scenes in Final Crisis.

A psychiatrist, Doctor Hurt is involved in a program that creates three "replacement Batmen" with the participation of the Gotham City Police Department. Sometime after the replacements are trained, Hurt joins the Department of Defense to oversee an isolation experiment. During this process, he gives Batman a post-hypnotic trigger connected to the phrase "Zur-En-Arrh".

Going over his notes on Batman's psychology, Hurt realizes that Batman is "powered by tragedy" and intends to traumatize the three replacements to make them better crimefighters.

Years later, Doctor Hurt is working with the Black Glove when they decide to target Batman and his allies. Hurt is presumed dead after a helicopter explosion, but survives and resurfaces in Mexico. With Joker working as an unreliable ally, Hurt releases a drug into Gotham's air to drive its citizens insane. Hurt shoots Dick Grayson in the head and attempts to force Damian Wayne to swear allegiance to him. However, Dick survives and eventually recovers while Batman defeats Hurt. Hurt escapes before the Joker subdues him.

Hurt also appears in Convergence, where he is killed in battle with Batman.
