Death Cavalier (デス・キャバリエ) is an undead rider knight and one of Ainz's undead summoned monsters.
A black-armored knight which rides a red-eyed unicorn, whose body is jet black and sporting two horns on its head. One can imagine that the rider is not human. It emanates an aura of mortal danger, as radiant as the sun. Its full plate armor pulses as though it was alive.
Death Cavaliers are strong creatures. Though they have the ability to properly speak unlike most undead.
