Rider (ライダー, Raidā?), Mounted Knight (騎乗兵?) and Heroic Spirit of the Mount (騎兵の英霊?), is one of the Four Cavalry Classes among the seven standard Servant classes summoned for the Holy Grail War. Servants placed within this Class are those known for riding mounts, whether living beasts or human constructs, during their lives. There are even some cases where legendary animals have been summoned as a Servant such as Vánagandr and Red Hare. They generally have lower attributes compared to the Three Knight Classes, but the abilities of the mounts described in their legends compensate by granting them powerful Noble Phantasms or abilities. They have the class abilities of Magic Resistance and a high rank in Riding, allowing them to fully utilize the abilities of their mounts. Depending on the rank, they can take full control of everything from simple horses, modern machinery like motorcycles and planes, and even Divine Beasts. Dragons are the only exception as the ability to ride them falls under a different Skill; however, rare exceptions do occur.
« The Rider tarot card proved to be the most difficult of the bunch. I was told to put Rider on something like a tank, and my first thought was the M1 Abrams. Of course it was a foolish thought, as a modern piece of equipment would look completely out of place on these tarot cards... I know, I know. So instead I wen with something that looked like the chariots they rode in the movie "Ben-Hur." But you know, the one they did for "Zero" was so much cooler. I feel like I should have done better! »
