Yamata Orochi is a jutsu used by Susanoo Mikoto. To use he stabs the Sword of Kusanagi in something (Usually the ground) he then flows chakra into the sword then makes the serpent seal. This causes a giant eight headed serpent that is made up of whatever the sword is stab into to appear. This just requires a lot of materials to create the serpent. Though he has stated that he does not like using this jutsu due to his dislike for serpents.
