The captain of the Straw Hat crew, Monkey D. Luffy, is one of the most recognizable anime designs alongside Goku and Naruto. Besides his straw hat, shaggy black hair, and toothy grin, many fans will recognize Luffy from his scars alone. Notably, Luffy has two scars: one under his left eye and an “X” across his chest. Luffy didn’t, however, always have these scars, and many people wonder where these trademark characteristics came from.
