Manga and Brotherhood
The Doctor is first seen in a flashback scene, when King Bradley becomes a Homunculus, injecting him with liquid Philosopher's Stone. Later he appears in Briggs to heal Solf J. Kimblee from his wound that he got in battle against Scar. After the attack on Central Edward Elric, Roy Mustang, Scar and Riza Hawkeye search the maze under central command for Mei Chan, they meet him, talking about the Promised Day. Mustang tries to kill him but he calls soldiers to help. These men are revealed to be failed Führer candidates and as such possess almost as good fighting abilities as Wrath himself. After a short fight Doctor activates a transmutation circle in Central which sucks Edward, Al, and Izumi Curtis to The Gate. Führer soldiers restrain Mustang, Hawkeye and Scar. The Doctor tries to persuade Mustang to try Human Transmutation but he refuses. The Doctor says they have no time and one of the Führer soldiers slashes Hawkeye's across her throat, causing her to bleed heavily. Mustang refuses to do Human Transmutation on sign form Hawkeye. The Doctor is then subdued by Jerso and the others defeat rest of the Führer soldiers. Relief, however, is short, as both Wrath and Pride arrive. Wrath pins Mustang to ground by stabbing swords through his palms. The Doctor praises Wrath but Pride unexpectedly stabs him through his back to use him as a human sacrifice. A Transmutation circle under them then activates, Pride and Mustang disappear. After Pride and Roy are gone and the smoke clears, the only thing left of him is a disgusting mass of flesh that resembles him, a by product of the human transmutation.
