Snake

, more commonly known as, are the signature summons of Orochimaru and his brief students, Sasuke and Anko. They vary greatly in size, from small enough to hide in one's sleeves to larger than most buildings. Appearing first in episode 27 of the Anime, Orochimaru frequently summons them as allies in battle, either having them attack for him or instructing them to carry out other tasks. Despite this, he treats them as disposable pawns, typically sending them into battles during which they are likely to be killed. Sasuke is equally unattached to these snakes, often summoning them only for use as a shield. While most snakes are very obedient and do what is instructed of them, the largest snake, Manda, will not help others without payment, demanding a sacrifice of a hundred humans in exchange for helping Orochimaru, yet even then would readily turn against Orochimaru if he thought he could win.
