In [i][[Umamusume]][/i], the Byerley Turk refers both to one of the Three Goddesses of the [i]Umamusume[/i] universe as well as a training AI based on her, who is one of the hosts of the Grand Masters scenario. She represents "Discipline" and is represented by the color yellow.

A [[horse girl]], she has short brown and black two-toned hair as well as purple eyes. She wears a yellow military-style outfit and has a scar across her left eye. Overall, she somewhat resembles [[Symboli Rudolf (umamusume)|]] (and not by coincidence, as described below). She has a crown-like accessory on [b]her right ear[/b].

She is based on the Byerley Turk, one of the foundation sires of the Thoroughbred breed of horses. His umamusume's military theme is based on the fact that the Byerley Turk was originally a war horse. Through Herod, he is the sire-line ancestor of about 4% of all Thoroughbreds. In the context of [i]Umamusume[/i], he is the real-life ancestor of only 6 characters: Those who are part of Partholon's sire-line ([[Symboli Rudolf (umamusume)|]], [[Tokai Teio (umamusume)|]], [[Tsurumaru Tsuyoshi (umamusume)|]], [[Samson Big (umamusume)|]] and [[Mejiro McQueen (umamusume)|]]) as well as [[Daitaku Helios (umamusume)|]].
