The Scarred Man, known more casually as "Scar" is a nameless lone serial killer and vigilante who targets State Alchemists for his own brand of lethal justice in accordance with the fundamental tenets of his religion and for the revenge of his slaughtered people and family. An Ishvalan survivor of the Ishvalan Civil War, Scar's moniker comes from the large X-shaped scar on his forehead and sports a conspicuous and intricate alchemical tattoo on his right arm, which originally belonged to his older brother, and which he uses as his murder weapon of choice.
And he is reprised by J. Michael Tatum in the English dub and Kenta Miyake in the Japanese dub.
