Levi Ackerman is a short, muscular soldier with short black hair styled in an undercut curtain and dull gray eyes. He is depicted as a "clean freak" and is often expressionless, making it difficult to determine his thoughts. Despite his blunt and coarse manner of speaking, he has a strong sense of morality and empathy, valuing human life and caring deeply for the welfare of his subordinates.
Despite his cold exterior, he is deeply affected by the loss of his comrades.
