Overview
Byerley Turk is a character in Umamusume Pretty Derby who appears as a training support AI in the Grand Masters scenario. Modeled after one of the world's Three Goddesses revered at Tracen Academy, she was created around the core concept of discipline. Driven by the firm conviction that forging true strength is essential to pioneering the future, she adopts a stern, military-minded approach to guide horse girls toward excellence while ensuring they fulfill their maximum potential.
Appearance
She has the features of a horse girl with horse ears and a tail. Her hair is short with a two-toned brown and black gradient between the front and back, and her eyes are purple. A scar runs across her left eye, and she wears a crown-like ornament on her right ear. Her attire consists of a yellow military-style uniform featuring a cropped jacket, suspenders, gloves, and a military side cap.
Personality
Byerley Turk possesses a disciplined and unyielding military temperament. She harbors no tolerance for weakness, constantly pushing horse girls to stay ahead of their competition through rigorous expectations. Although her demeanor seems overly strict at first glance, her actions are rooted in a deep, noble desire to support the growth and future of every athlete. Once horse girls realize her noble intentions, they place immense trust in her guidance. In contrast to her stern exterior, she secretly holds a fondness for small trinkets and accessories shaped like bird feathers or wings.
Abilities
In the Grand Masters scenario, she operates as a training support AI. Her unique wisdom ability enables friendship training to trigger for support cards participating in a session, even if the training type differs from the card's specialty. The magnitude of this training bonus scales with the current level of the facility, making its impact lower during early training phases. Additionally, choices linked to her support card primarily enhance an athlete's stamina, power, and guts parameters.
Background
Within the world of Umamusume Pretty Derby, Byerley Turk is revered as one of the Three Goddesses who laid the foundations of racing history, with a statue sculpted in her image standing at Tracen Academy. When the Grand Masters training program was introduced, she manifested as an artificial intelligence embodying discipline to oversee the training of young horse girls. Her historical namesake is one of the three foundational sires of the Thoroughbred breed, known for serving as a warhorse in military campaigns such as the Battle of the Boyne before transitioning to breeding.
Relationships
Byerley Turk works alongside Darley Arabian and Godolphin Barb, fellow entities representing the Three Goddesses who together guide the athletes at Tracen Academy. While she maintains an exacting standard with the academy's horse girls, her unwavering commitment earns their respect and faith. In terms of historical bloodlines, she serves as the direct sire-line ancestor to the real-life inspirations of several characters, including Symboli Rudolf, Tokai Teio, Mejiro McQueen, Tsurumaru Tsuyoshi, Samson Big, and Daitaku Helios.
Trivia
Her martial demeanor and military costume stem from her real-world counterpart's history as a military mount owned by Captain Byerley. The name Byerley comes from her historical owner, while Turk references her horse breed origin. Although her direct sire line accounts for roughly 3.3 percent of modern Thoroughbred gene pools, her descendant Herod became a dominant cornerstone in horse breeding history, passing down a lasting legacy through lines such as Partholon.
