The Kyodaija (巨大蛇, literally "Giant Snakes") are giant snakes, often summoned by Orochimaru during battle. There are many different kinds of Kyodaija. For instance, the Kyodaija that was summoned during the invasion of Konoha had marks on its skin similar to the Cursed Seal of Heaven, while the ones summoned by Orochimaru in the Forest of Death had no such marks. Anko Mitarashi also summoned a blue-colored snake of similar size during the Land of the Sea filler arc to protect Naruto, Shino, and Ino from a cave-in. The four took shelter within its mouth as it broke free of the cave. Over the timeskip, Sasuke Uchiha has the snake summoning contract applied to his arm, allowing him to summon snakes in combat.
