Levi Ackerman, often formally referred to as Captain Levi, is the squad captain of the Special Operations Squad within the Survey Corps and is widely known as humanity’s strongest soldier.

Levi has short, straight black hair styled in an undercut curtain, as well as narrow, intimidating dull gray eyes with dark circles under them and a deceptively youthful face. He is quite short, but his physique is well-developed in musculature from extensive vertical maneuvering equipment usage. He is usually either frowning or expressionless; that, plus his extremely calm demeanor, often makes it difficult for others to guess what he is thinking.
