Four Horsemen of the Apocalypse is Koshaku Kyuuketsuki's technique and is one of his most powerful. Koshaku has prepared the bodies of the eight dead clan members he killed during the slaughter, and merged every two bodies into one, to create four grotesque four-armed beings with double the muscle mass and physical abilities of a Jounin. The beings are controlled by his making hand movements, and rush an opponent to strike them. They are still merely mutated corpses being used for battle, and a very strong fire or lightning technique can completely eradicate them. They also do not possess any of the abilities they once had in their lives.
