Pieck's father is a middle-aged man with dark hair and beard. He is seen wearing a white shirt, a jacket and a hat.
While he was attained by a grave illness, his daughter selflessly volunteered herself to join the Warriors and succeeded in earning the right to inherit the Cart Titan, this managed to save his life by providing him the necessary medicaments. However, he expressed his distress and despair by his daughter's sacrifice and foreseeable death by the Curse of Ymir.
Pieck's father is among a group of Eldians who desperately try to convince Liberio's guards to allow them to leave after receiving Eren's message announcing the Rumbling. Unfortunately, the guards do not believe the crowd, as only Eldians were able to see Eren's broadcast, and accuse the Eldians of plotting to escape their internment camps. He and the others begin surrendering to the guards until Leonhart lashes out against them.
