Thomas Wagner

A blond-haired boy. He is from the Trost District. A member of the 34th Training Corps squad (Trost District Defense Battle Division) along with Eren, Armin, and others. During the appearance of the Colossal Titan, he was in the 4th fixed artillery maintenance squad, in the same squad as Eren, Connie, Sasha, Samuel, and Mina. While all the top performers expressed their intention to join the Military Police Brigade, he was inspired by Eren's passionate desire to join the Survey Corps and shared the same hope.

However, during his first battle in the Trost District Defense Battle, he was attacked and swallowed whole by an abnormal Titan, resulting in his death. The abnormal Titan that ate Thomas was later killed by Eren after he transformed into a Titan.

During Eren's 3D maneuvering training, he assisted the instructor, Keith.
