Haroku

Haroku is the prince of snakes, along with Manda, and is summoned by Ryun and Tora Uchiha.

Personality
He is very calm, yet prideful, believing himself superior to most everyone, but he does what Ryun and Tora ask. Haroku obviously will not be in anything if there is nothing in it for himself, showing his greed. Though he has mentioned at some point that he likes being summoned by Ryun and Tora. He seems to respect Ryun. He's very strong and he knows it.

Abilities
Haroku is very powerful, and able to stand his own against Gamabunta and Katsuyu and even his brother, Manda. He is extremely fast, as he is quickly able to dodge and disable opponents, and is incredibly intelligent. It's also obvious that he's well known, as Gamakou is afraid of him just because of his gaze. He is also able to shed his skin somewhat like a Replacement jutsu, just like Manda, and to move underground.
