Three Tails (Sanbi), Isonade

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.

Personal notes: Well, if this bijuu doesn’t scream KISAME to you, then this note is indeed useful. The Samehada connection is frightening (absorbs chakra), but there can be more about it, explaining WHY Kisame’s chakra reserve is SO big (as being the biggest in Akatsuki).
