Henry Douglas

Douglas is formal and professional in his limited appearances. He operates within the military bureaucracy and approaches investigations through official procedure.

Canon provides little material about his personal life, beliefs or ambitions, so his characterization remains primarily occupational.

Douglas has no established alchemical or supernatural abilities.

As a colonel attached to Military Police headquarters, he holds significant rank and administrative authority. His demonstrated responsibilities concern military law enforcement and investigation rather than frontline combat.

Douglas appears in Central in connection with the investigation following Hughes's murder. His involvement places him among the military officials handling one of the most sensitive cases within Central Command.

His role remains peripheral, with the larger investigation increasingly driven by Roy Mustang and the people personally connected to Hughes.

Maes Hughes is the military officer whose murder brings Douglas into the relevant investigation.

Roy Mustang conducts his own increasingly suspicious inquiry into the circumstances surrounding Hughes's death.

Maria Ross becomes a central subject of the official investigation after evidence is produced against her.
