Manda
Manda is the personal summon of Orochimaru.
Manda was the largest snake in the world, before being recently out-sized by his clone, Manda II. He easily towers over buildings, trees, and large rock formations. Due to his length, he is even larger than Gamabunta and Katsuyu, easily coiling around Katsuyu and having more length behind him, and he could open his jaws wide enough to swallow Gamabunta whole.
He is colored purple, and has black rings running down intervals on his body. He has massive fangs, though they are arranged in a way similar to that of a constrictor snake instead of a viper or other venomous snake species, presumably carrying venom in them from the way they were designed, and green eyes. He also has four horn-like protrusions on his head.
