Horses are mammals that live on Planet Earth and Mobius. Throughout history, horses have been closely associated with humans, often used to carry supplies or act as a steed for a brave knight. They even fulfilled this act on Mobius once in their history:
- Xavier Pendragon has an irrational hatred of horses, as explained in the Eternal Champions Special.
- Joe Musashi is shown to be a skilled horse rider, controlling one whilst performing archery on Mount Hotaka.
- Centaurs are half horse, half human creatures. A whole town of them live in Portstable, an area of the Nameless Zone, whilst Chester is another in the Shining Force series.
- Speaking horses once existed, as evidenced in the Bravehog story. Aligned with King Leer and his hyena kingdom, the horses transported the evil creatures around and revealed to the badger tribe that they put up with the evil acts as long they feed the horses oats. They were not present in the final battle against the hyenas.
- Amy Rose arrived to save Tekno the Canary on the back of a horse in 1870s Kansas during Out of Time. In return, the local sheriff arrived on his own horse to save them from Colonel Granite.
- The soldiers of Romanus once seemed to ride around on horses, although they may have been robotic, judging by their shiny coats.
- Several walking, talking horses lived in an area somewhere outside the main city of Shanazar. The Knight's Baron led these evil horses in a march against other kingdoms, tricking Amy and Sonic the Hedgehog into fighting their enemies, the Kritturs. Once the heroes discovered who the true villains were, Amy convinced the horses to ignore their kingdom from then on.
- A horse acted as a security guard for the Kane Broadcasting Company headquarters, stopping the Freedom Fighters from entering until he saw their armbands. Unfortunately, he was attacked by Fockewulf de Shrike for not letting him through.
Outside of these areas, alternatives were used for horses. The Legend of the Golden Axe has heroes and villains riding on a variety of Bizarrian steeds. Recent Nameless Zone stories see that winged horses are a mode of transport within the Land Beyond.
