Lauda has neck-length brown hair that he keeps tied back. He is only ever seen wearing the typical uniform of the Survey Corps.
Lauda is a brave and conditioned soldier, demonstrated by the way he took charge of Team 2 under Hange's orders.
Lauda is among the soldiers who participate in the battle with Annie Leonhart in Stohess District. When Eren Yeager manages to temporarily stop Annie's attempt to escape Stohess, Lauda and others in the Fourth Squad attempt to cut off Annie's escape route.
After Bertolt Hoover and Reiner Braun betray the Survey Corps and attempt to kidnap Eren and Ymir, Hange Zoë attacks Bertolt, leaving Lauda in charge of Team 2. The subsequent battle leaves Lauda seriously injured, and unable to participate in the mission to rescue Eren and Ymir.
- Lauda is not among the 9 survivors of the Battle of Shiganshina District which suggests he is either dead or left the Survey Corps prior.
