Levi Ackermann

Levi Ackerman (often called Captain Levi) is one of the most iconic characters in Attack on Titan.

He is widely regarded as humanity's strongest soldier, serving as the squad captain of the Survey Corps' Special Operations Squad (commonly known as Levi Squad). Despite his short stature (160 cm / 5'3"), Levi possesses extraordinary combat ability, particularly when using Omni-Directional Mobility (ODM) gear — his precision, speed, and technique are considered unmatched.

Personality-wise, Levi is:

• Extremely disciplined and clean-obsessed (a famous germaphobe)
• Calm and stoic under pressure
• Blunt, sarcastic, and often harsh in speech
• Deeply loyal to his comrades (especially Erwin Smith) while appearing cold on the surface
• Ruthlessly pragmatic in battle

His backstory involves growing up in the underground city, being trained by his uncle Kenny Ackerman, and later joining the Survey Corps. His Ackerman bloodline gives him exceptional physical strength and combat instincts when awakened.

In short: small, deadly, foul-mouthed cleaning freak who's probably the most respected and feared soldier within the walls.
