Edit
In Umamusume, the Darley Arabian refers both to one of the Three Goddesses of the Umamusume universe as well as a training AI based on her, who is one of the hosts of the Grand Masters scenario. She represents "Bravery" and is represented by the color red.
A horse girl, she has long red hair with a white blaze marking as well as green eyes. She has distinctively dark skin and wears a summer casual outfit bearing her shoulders. She has an accessory on her right ear.
She is based on the Darley Arabian, one of the foundation sires of the Thoroughbred breed of horses. Through Eclipse, he is the sire-line ancestor of 95% of all Thoroughbreds. In the context of Umamusume, he is the real-life sire-line ancestor of the vast majority of the cast.
