The Star Horse is a mysterious breed that appears in the Starshine Legacy games and related side material. The breed first appeared on Jorvik after the legendary meteor shower hundreds of years ago. This breed is known for it's bright white coat and blue manes. Due to its extremely proud and wild ways, the breed is said to be almost completely untrainable.
Only one horse was shown as an example of this breed, and that was Lisa's horse Starshine. He Remained the only Star Horse until sometime later when the Starshine Legacy comics began to refer to him as a Starbreed, which was described as a horse with the same characteristics of the Star Horse but just under a different name.
Star Stable Online
Starshine was presented as a Star Horse in Star Stable Online for some time until his model was updated. Starshine became a Jorvik Wild Horse and Starbreed became an entirely new concept. This marked the removal of the Star Horse from Star Stable's canon.
