Gold Toothed Doctor

The Gold Toothed Doctor was a character in the Fullmetal Alchemist manga and 2009 anime Brotherhood. He is an old man who possesses his own Philosopher's Stone and was responsible for the creation of Wrath, or Fuehrer King Bradley. He is never named and only ever adressed as Doctor. He gets his name from his one gleaming golden tooth.

Description
The Gold Toothed Doctor is a short old man, possibly in his sixties. He has short auburn hair and a small moustache. He was known for his one golden tooth, hence his nickname. His glasses are usually seen to be very shiny, however when the glint is gone, you can see his eyes are spaced apart (almost like a fish's). He always wore a white lab coat with the sleeve's rolled up on top of a maroon dress shirt.

Role in the Story
A younger version of the Doctor is seen in a flashback when Wrath is talking to Roy Mustang, discussing his creation, it is seen that he always had the golden tooth then. He appears later at Fort Briggs to heal Solf J. Kimblee, who lost his fight badly against the vengefull Ishvalan Scar. He then is absent from the story for a long period of time, that is, until Edward and co. run into him after Envy commits suicide, continuing on their search for the Homunculi's Father. He is shocked to see that Roy Mustang is with them, which leads into thier plan perfectly, being that Mustang has been slated to be the Fifth Sacrifice in Father's Nationwide Transmutation Circle. He himself does not engage them himself, however, he still has the people who were going to be Wrath at his disposal, and they attack the band of heroes, while they're no Fuerher Bradley, they still have heightened battle know how and tactics. It is later found that they were really just a distraction as the Doctor finished his transmutation circle, which then activated the circle in Central, which transported Edward, Izumi Curtis, and Alphonse Elric to Father's lair (Hoenheim was already in his lair). Afterwords, The Doctor knew his job was to get Mustang to open the portal of truth. To do this, he had one of his men severely injure his suboordinate Riza Hawkeye. He informed Mustang that if he refused to open the portal, the girl would die, but if he did, he would use his Philosopher's Stone to save her life. Even still, Mustang's loyalty to his nation made him refuse the doctor's offer. Before he can react, however, the doctor is subdued by back up from some other heroes who had gone searching another way. However, thier relief is short, as Pride and Wrath arrive. The Doctor praises Wrath as he incapacitates many of the heroes, but is unexpectedly stabbed by Pride to be used as a raw human sacrifice to force Mustang through the gate. When the smoke clears, it is revealed that the Golden Toothed Doctor is now a disgusting mass of flesh. His only resemblance is his golden tooth and his crooked eyes.

Abilities
The Golden Toothed Doctor has preformed numerous inhumane experiments with alchemy and his Philosopher's Stone. He is primarily oriented on healing and medical alchemy, but he is also shown to possess great knowledge of creating Philosopher's Stones. Despite all of this, he is also shown to be very intelligent.
