Manda

Manda is the king of snakes and is summoned by Orochimaru. He demands 100 human sacrifices after he is summoned. He first appears in Naruto Episode 96, summoned jointly by Orochimaru and Kabuto(as Orochimaru had his arms rendered useless by the Third Hokage in episode 78).

He is very snobbish and prideful, believing himself superior to everyone, and while he does what Orochimaru asks, it seems to be only because he wants to. When Kabuto attempts to calm him (note that Kabuto calls him 'Lord Manda', again reinforcing the snake's pride) Manda merely tells him to shut up, calling him a 'bug.' Kabuto at this point says something about Manda betraying them if he finds out that Orochimaru's arms are useless, making a comment about his loyalty. Manda obviously will not be in anything if there is nothing in it for himself, showing his greed. He mentions at some point that he doesn't like being summoned, leaving the impression that Orochimaru doesn't do that often. He doesn't seem to respect Orochimaru at all, even going to the extent of threatening to eat the Sannin when he is angry. When exchanging insults with Gamabunta he once again shows off his pride, as well as his confidence. He's very strong and he knows it, threatening to 'pop' Gamabunta.

Manda is very powerful, and able to stand his own against Gamabunta and Katsuyu. He is extremely fast, as he is quickly able to dodge and disable Katsuyu, and incredibly intelligent. It's also obvious that he's well known, as Gamakichi is afraid of him just because of his gaze. He is also able to shed his skin somewhat like a Replacement jutsu, which is seen during the battle with Gamabunta and Katsuyu, and to move underground. However, he is disabled and put out of the fight when Tsunade shoved Gamabunta's dagger through his mouth, pinning him to the ground.

He was killed by Deidara's suicide explosion when Sasuke used him as a shield. Suigetsu nagged Sasuke for doing that.
