Many notable examples of horses appear in the Castlevania series in many different roles beyond being just mounts.
In the majority of their apparitions in the series, horses are portrayed as enemies, such as equine demons, hybrids or as undead creatures. But they also appear as special attacks, landmarks or benevolent spirits.
The Valhalla Knight, the Dullahan in Castlevania: Circle of the Moon, and the Dead Warriors are examples of horses being ridden by knights. They gallop back and forth on horses that are missing their hind side, patrolling a set area. Horses are also seen pulling chariots in the series such as for Richter Belmont on Rondo of Blood, and for the Gladiator in Castlevania: Aria of Sorrow, which shoots arrows. Nightmare is a ghostly horse, which may or may not have a rider, which has a skeletal back half, but a fleshy front half.
Mr. Hed is a disembodied, floating horse head that will attack the player in the first stage of the game, The Ruined Mansion. It will remain in place while undisturbed but, if Simon approaches, it will charge in his direction and rise in the air trying to tackle him.
Later in the stage, the skeleton knight Rowdain appears as a boss, riding a skeletal horse capable of shooting fireballs. By dealing enough damage to them, the horse is destroyed, leaving Rowdain to attack alone.
The Valhalla Knight is seen running back and forth in some places of the castle, riding an undead horse that has been ripped in half. If the player attempts to jump over this enemy, the knight will point his spear at them, at which point the horse will take a leap when it gets close enough to Alucard.
The Hellfire Beast is a thunder demon with a horse head. It is inspired on the Goetic demon Amduscias, which took the form of a unicorn.
Living horses are seen being ridden by Maria and Richter, but only on the extra modes with these characters and only in the Saturn port of Symphony of the Night. It is also possible to summon a horse spirit with Alucard via the Shield Rod+Knight Shield combo, increasing Alucard's attack by 20 points.
Nightmare makes its first appearance in the form of a horse in this game. It patrols different areas of the castle by running back and forth, similarly to the Dead Warriors. Some of them have a rider, while others do not. By capturing the Nightmare's soul, Soma Cruz gains the ability to shoot Nightmares as projectiles.
Concept art suggests that the Nightmare was intended to show up in this game, but no such enemy appears. Yet the Valhalla Knight returns from Symphony of the Night, rebranded as "Dead Warrior".
Nightmares return in this game as enemies in the Tymeo Mountains, using the design seen on concept art for Dawn of Sorrow. They are armored horses whose back has decayed and exposed its bones. They run across the room attempting to trample the player, and drop Horse Hair, which is used by George to create his violin.
Eligor is a gigantic armored centaur boss whose body is covered in weapons. Shanoa must maneuver between Eligor's legs while avoiding his hooves, evading giant arrows and his tail that shoots out like a harpoon. Defeating him without taking damage awards the player with a Boss Medal describing Eligor as a demon-horse rider.
Horses are important animals which role as mounts in Castlevania: Lords of Shadow. During the game, Gabriel's horse makes its first appearance as a mount, but it dies when Gabriel is fighting with werewolves. As the game begins, Pan takes form of a horse who is able to ride through the Hunting Path. Gabriel rides this horse to escape wargs.
