Манда

The largest and strongest of snakes, the Snake King. After each battle, it demanded a hundred human sacrifices from Orochimaru. It was summoned by Sasuke in the fight against Deidara when the latter decided to self-destruct, with Sasuke himself surviving, while Manda, wounded from the ordeal, perished. Sometime later, Kabuto created an even more powerful snake, Manda II, from Manda's cells.
