Levi Ackerman
Levi is the captain of a special operations squad within the "Survey Corps".
Considered the strongest human soldier within the walls, he brings out his fearsome side. The way Levi stares with his piercing eyes gives anyone the creeps.
Levi is obsessed with cleanliness, enjoying having his equipment and rooms always clean and tidy.
Rarely showing emotions, Levi is not usually friendly, being impossible to wipe a smile of happiness from his face.
His lines are often inappropriate or belittling.
