Pieck Finger is an Eldian who served as one of Marley's Warriors and possessed the power of the Cart Titan.
Pieck is a short young woman with long, disheveled shoulder-length black hair, a Greek nose and relaxed dark brown eyes. She wears a white blouse, a long trench coat, and skirt which goes down to her ankles as well as black lace-up boots. She also wears the Eldian armband on her left arm, as required of all Eldians under the authority of Marley. Since the end of the Marley Mid-East War, Pieck has been walking with a crutch, having lost some grasp on the ability to walk upright after spending two months in her Cart Titan form without interruption, which she claims is typical for her. However, she can be seen walking on all fours when there are few people around, as she claims it "feels more natural." During her infiltration on Paradis Island, Pieck stole a Survey Corps uniform and used it as a disguise to infiltrate the group known as the Yeagerists.
Pieck is shown to be somewhat sweet and kind, consistently shown to care about her fellow Warriors and the Warrior candidates. She is incredibly intelligent, able to quickly deduce a situation. When the Warriors were discussing the prospect of using the Tybur family to assist in their operations, Pieck was able to quickly figure things out, and Zeke Yeager implies this happens quite often. However, Pieck is usually shown to be quite eccentric and easy going. During the train ride to Liberio, Pieck gladly gave Colt Grice a drink when he asked for one, which led to him getting drunk and leading the other Eldian soldiers in a chant in favor of Gabi Braun. As a result of constantly being in her Titan form, Pieck has shown the habit of walking on all fours when few people are around, stating that it feels more natural and even curling up on a sofa like a cat; she is still capable of walking upright, although she occasionally requires a crutch to do so.

History: Pieck grew up in the Liberio Internment Zone and lost her mother early on in childhood; seeing that her father had gotten sick and would not survive long without proper medical care, Pieck joined the Warrior program as soon as she was eligible. After performing well enough to be selected to inherit one of the Marleyan Titans, Pieck was able to secure her father the treatment he needed.
