Scar

A major Ishbalan character in both the anime and manga, Scar is one of the primary antagonists throughout the series, though his role becomes more complex as the series develops.

His real name is never revealed, but he is referred to as "Scar" because of the X-shaped scar on his face. Scar's right arm, which is tattooed with a rare transmutation circle, was given to him by his brother shortly before he died.

Scar believes himself to be an instrument of God, and kills State Alchemists using his alchemical skills, despite the fact that he believes alchemy is an abomination against the natural world.
