Jinchuuriki: Hoshigaki Kisame?
Tale in the Legend of the Tailed Beasts: Isonade is a shark shaped Bijuu with a sharp horn on the forehead. It lives in the deep waters on the West of Japan, fighting pirates. Every few months, Isonade will swim to the surface of the sea from the deep waters, to breath some fresh air. However, when he does this, storms erupt, oceans rage, and all ships will be swallowed by him as food. Isonade has a subordinate fish called Samehada (same name as Kisame's Sword). Depicted differently, but with same pronunciation). Samehada attaches itself to Isonade’s stomach, and absorbs its food to create huge amounts of chakra, proceeding to send it back to its body. Samehada’s power can enable Isonade to get 5 times the quantity of chakra it could originally get. Therefore, when Isonade battles, he will have unlimited chakra to receive from Samehada.

Situation in the Ancient War of the 9 Gods: Battled 5 times; 2 Wins, 3 Losses
Wins: Shukaku, Sokou
Losses: Houkou, Yamata no Orochi, Kyuubi
Fate: A ninja called Sarutobi (That’s right, but we don’t know if it’s the series’ Sandaime), in the legend, effectively eliminated Raijuu by using the technique “Kinjutsu: Raikiri”. (Now the confusion starts. This is supposed to be Kakashi’s move, but the way of writing may be different from the actual jutsu, and Kishimoto probably changed this legend to fit the story anyway). What actually happens is that the technique counters the lightning released by Raijuu by cutting it, making the beast receive its own attack, and become severely wounded. (Thus the name lightning edge.) He then is sealed by Sarutobi with the “Tool of Power: Hidden Thunder Prison” into the seal in the Thunder Shrine.
Japanese Myth Appearance: A species of weasel with golden yellow fur. The whole body’s fur grows upright. Its six tails take a lightning shape, just like the ancient God of Thunder.

More info about Raijuu:
Raijuu is also depicted as the companion of Raiden, the Shinto god of lightning. While the demon is generally calm and harmless, during thunderstorms, it becomes agitated and leaps about in trees, fields, and even buildings (trees that have been struck by lightning are said to have been scratched by Raijuu's claws).
Another of its peculiar behaviors is sleeping in human navels. This prompts Raiden to shoot arrows at Raijuu to wake the creature up, thus harming the person in whose belly the demon is resting. Superstitious people therefore often sleep on their stomachs during bad weather. Other legends say that Raijuu will only hide in the navels of people who sleep outdoors.
