* The Mare: Spirit's mother, she is caring and protective.
* The Old Stallion: The leader of the herd, he is wise and experienced.
* The Foals: Younger horses, they are playful and curious.
However, the horse that's often referred to as "Spirit's best friend" and plays a significant role in the story is a bay horse. While he doesn't have an official name, he is known for being a loyal companion to Spirit.
It's worth noting that the 2002 movie is based on the graphic novel series "Spirit: Stallion of the Cimarron" by Jaime Diaz, and there, the horses have names. However, the movie and the graphic novel are different, and the movie characters do not use the names from the book.
