Robony is a mechanical horse that crashes to Earth from Planet Muzanda inside a meteor-like object, landing near Mount Fuji. It serves as the primary mecha steed and combat partner for the protagonist when he transforms into the hero Devander. Robony provides essential transportation and combat support during battles against King Bull and his invading forces from Planet Muzanda, enabling Devander to confront their attempts to extract Earth's "Gaia Energy." Despite its extraterrestrial origins, Robony integrates into terrestrial life, forming a close operational bond with Lovely, an organic horse living on the farm with Devander's human alter ego and his sister. This character appears exclusively within the 2012 OVA narrative.
