Rider is the Rider-class Servant of Waver Velvet in the Fourth Holy Grail War of Fate/Zero. Rider's identity is Alexander the Great, also known as Iskandar and Al-Iskandar, the King of Conquerors. He wears bronze armor with cuffs and greaves with fringes that leaves his arms and thighs unprotected. He wears a thick mantle, with fringes like his cuffs, dyed in a similar red to his hair. It is luxuriously decorated, and looks like a curtain wrapping the stage of a theater!
