Christopher Hutton
Christopher William Clayton Hutton (1893–1965) a soldier, airman, journalist and inventor, was recruited as an intelligence officer to work for MI9, a branch of the British Military Intelligence, during the Second World War. Known as 'Clutty' to his friends, he was engaged towards the end of 1939 by the War Office to work under Major (later Brigadier) Norman Crockatt, in order to set up and run operations to create and distribute escape and evasion aids for Allied servicemen. Hutton's small team identified suitable manufacturers, ensured supplies and devised methods by which the concealed aids could be sent to prisoner of war camps.
Simon Hurt
Hurt was believed to be dead after a helicopter explosion, but somehow survived and reappeared approximately six months later in Mexico, disguised as the drug lord El Penitente, but left to return to Gotham City. With the Joker working as an unreliable ally, Hurt used the Circus of Crime to release a drug into Gotham's air with the intention of driving the city mad, subsequently making a public return as Thomas with the intention of setting up his headquarters in the Batcave. Hurt shot Dick Grayson in the back of the head and attempted to force Damian Wayne to swear allegiance to him in order to save Grayson's life. However, Grayson and Damian had already anticipated his attack; the attempts to open the box that Bruce revealing nothing but a Batarang and a note saying "Gotcha!", the room subsequently filling with smoke as another Batman appears, marking Bruce's return to the fold. It is revealed that he's a relative of the Wayne family from the 17th century whose true identity is Thomas Wayne, a black sheep of the family for his devil worshippings. Hurt prolonged his life through a series of occult rituals. In a story immediately previous, Batman states that Darkseid is attempting to "incarnate . . . in Hurt . . . in the Doctor". In the subsequent confrontation, Hurt attempts—and fails—to trap Bruce in a prison in the Batcave, but nevertheless escapes through the cave's water access while Bruce is busy rescuing Alfred. Having escaped to a graveyard, Hurt is confronted and defeated by the Joker when he slips on a banana peel and breaks his neck. The Joker doses Hurt with Joker venom and buries him alive, claiming that he proved to be a disappointment as a "new" arch-enemy. It is revealed that Dick has survived the injuries despite Hurt's intent to eventually render him comatose and nearly brain dead. The Joker claims that he has "taken care" of Hurt, but Bruce is not quite willing to believe that the Doctor is truly dead.
