halo (racehorse)

American Thoroughbred racehorse. A competent racer in his own regard, with nine wins out of 31 starts, who was preferentially a turf runner. Best known for his career as a stud, having sired Sunday Silence and Goodbye Halo among many others.

Infrequently depicted as an Umamusume - often with a muzzle or some sort of mask; the real Halo bit hard and often, and was frequently muzzled to prevent him from chewing on the fences or on an unsuspecting stablehand.
