Levi Ackerman[1].

She is short and slender, yet flexible, an advantage when using the Three-Dimensional Maneuvering Equipment, allowing her greater speed and agility. Her hair is black, short, and straight, with the temples and nape of her neck shaved (like many male characters). Her eyes are small, narrow, and bluish-gray. She is characterized by her permanent, skeptical expression, which seems unchanging. He has frequently been seen wearing the standard military uniform, which is worn under the green Survey Corps cape on expeditions. When he was forced to take time off due to his ankle injury, he wore a black suit and tie. He mostly wears casual attire consisting of a green shirt and jeans. He lost his right eye and three fingers on his left hand after being blasted at point-blank range by Zeke Jaeger with a Lightning Lance, which also left him with a scar running from his chin to his forehead on the right side of his face. In the story's epilogue, three years after the Rumbling, Levi wears a formal suit with leather shoes and uses a wheelchair due to being paralyzed after the fight against Eren.

Levi is a serious person, with a firm character and clear ideas. He has a great respect for discipline and is a conscript with enormous potential to be a leader, as his orders are always clear and precise, with no one daring to question his authority. His seriousness and coldness convey that kind of respect, especially this first factor, as he is a man of few words and rarely expresses his feelings. He is fully aware of the responsibility that comes with managing a group of soldiers, and that depending on the nature of his orders, he can lead those soldiers to certain death. His expression varies between seriousness and neutrality, and it's very unusual to see him smile. However, that doesn't mean he doesn't feel anything. It's true that he's not the most emotional person on the planet, but that doesn't excuse his lack of sensitivity or empathy. He cares about his comrades and those he's trusted. He tries to do everything possible to protect them and always considers his actions, trying to cause as little harm as possible. However, being a leader, he shouldn't openly show these feelings, which is why he hides everything behind a serious and somewhat distant expression. He doesn't allow himself to be flattered by words, preferring to be guided by actions rather than false promises. He's somewhat distrustful of people he doesn't know, but once those people gain his trust, they become someone he holds in high regard, even though he's not someone who flatters with words. He's small in size, but despite this, he displays the mind and maturity of an adult, as well as the cunning of a soldier who has endured all kinds of hardships. It's easy to anger him, but very difficult to enrage him to the point of losing his temper. He has just the right amount of patience and always seems to have the right word for every situation.

He tends to get annoyed by frivolous things, such as booing in a crowd, loud voices, and especially actions committed in a reckless manner. He has very little patience with such people and tends to ignore them or give them warning glances to correct their behavior.

He is quite a perfectionist and has an unhealthy obsession with order and cleanliness, being called "clean freak" by Hange Zoë.
