Levi

Levi has short, straight, black hair that is parted to the right with the ends cut roughly; narrow, intimidating, dull grey-blue eyes with dark circles underneath them due to lack of sleep; and a deceptively youthful face. He is short in stature, but has well-developed muscles due to his frequent use of his vertical maneuvering gear. Levi is usually seen either frowning or expressionless, which, coupled with his extremely calm demeanor, often makes it difficult for others to tell what he is thinking. He is most often seen wearing his Survey Corps uniform, with a light grey button-up shirt underneath and his signature jabot. When going on expeditions beyond the walls, he also wears a green hooded cape with the Survey Corps emblem on the back. When Levi was forced to give up his captaincy due to injury, he wore a black suit, a simple white shirt, black patent leather shoes and the same white jabot.

Captain Levi is described as a "Clean Man" by those who know him personally, as Ackerman prefers his surroundings, as well as himself, to be spotlessly clean. He dislikes getting dirty, and has been known to wipe his own blood-stained blades clean while still on the battlefield. However, he will not hesitate to touch dirt if he deems it necessary.
Despite his love of cleanliness, Levi is very aloof and uncommunicative. He rarely shows emotion, leaving a bad impression on others. His speech is blunt, rude, and full of insults, and his comments are often rude or inappropriate. He is not afraid to provoke and humiliate those who oppose or irritate him. His sense of humor tends to be vulgar, offensive, and dark. All this makes him very difficult to communicate with for most people.
At the same time, he has no problem showing open disdain for any other people, and especially for those in power.
Although Levi rarely shows it, he has a sense of morality and empathy. He places great importance on preserving human life. Due to his dangerous profession and his personal moral principles, Levi cares about the well-being of his subordinates.
Despite being Erwin's subordinate, Levi acts quite independently. Many of his Titan kills were accomplished alone without the direct cooperation of other soldiers. Ackerman does not hesitate to give orders when necessary, but does not see himself as a leader like Erwin Smith.
Levi knows that his fighting skills are on a different level than almost any other soldier alive. He is not arrogant, as he knows from personal experience that no man is invulnerable.
Sometimes Levi loses his cool and uses threats, including violence, to force others to listen to him, even if they are members of the Survey Corps.

Levi collects black tea. Levi would like to open a tea shop one day. He once got a tea set, but when he grabbed the handle of the cup, the handle broke off and the cup itself fell and broke. Out of fear that this would happen again, he no longer holds cups like normal people. Levi has a good tolerance for alcohol, or rather, he does not get drunk. He sleeps on average 2-3 hours. Levi hates mold the most.
