Levi Ackerman

Levi was born to a woman named Kuchel Ackerman and lived in the Underground. His mother died, and his uncle Kenny Ackerman took him in and raised him. Kenny taught Levi knife skills and how to get along with people. Levi is the leader of the Special Operations Squad in the Survey Corps. He was scouted by Erwin Smith and joined the Survey Corps, where he became one of Erwin's most trusted men. He is often seen with an expressionless face; he is cold, distant, and strict, but he has strong leadership skills that inspire others. He is also known to be a "clean freak."
