Name:Kaku Shichibi
Jinchuuriki: Deidara!?!
Tale in the Legend of the Tailed Beasts: Kaku is a bijuu in the form of badger. Its Kanji is also read as Mujina, which is the name the Japanese subspecies of badger (Meles Meles Anaguma) receives in some parts of Japan. It has seven tails, and is the smallest bijuu out of the nine; though it is the most cunning and stealthy. Kaku hunts its prey underground most of the time. It kills by crumbling/destroying the piece of land that is under its target, making it fall right into his open mouth. Above land, whenever he is around he can transform into any type of creature, but he is unable to do it if he doesn’t have clay.
Situation in the Ancient War of the 9 Gods: Battled 4 times; 1 Win, 3 Flees
Wins: Sokou
Escapes: Nekomata, Isonade, Yamata no Orochi
Fate: Kaku’s storehouse of clay in a hole is found, and is burned by warriors. Kaku is unable to transform, and is defeated by the brave warrior Ikkyo Soujin, who proceeds to seal it with the “Tool of Power: Remnant Earth Altar” into the seal in the Earth Shrine.
Japanese Myth Appearance: Kaku is the smallest Bijuu. It has a blue color, and is good at using clay camouflage. Kaku is very difficult to bump into.

More info about Kaku:
During the Kamakura and Muromachi eras, some stories began to include more frightening, man-eating badger. The otogizoshi story of "Kachi-kachi Yama" features a badger that clubs an old lady to death and serves her to her unknowing husband as "old lady soup". Mujina is an old Japanese term for a badger. In Japanese folklore, these animals were avid shapeshifters, and one of the forms they were purported to take was that of a faceless ghost. This particular sort of monster is often referred to by English speakers as a mujina, but the Japanese know them as nopperabou.

Yamata no Orochi or Hachimata Hachibi
Jinchuuriki: Orochimaru?
Tale in the Legend of the Tailed Beasts: Yamata no Orochi is a Snake bijuu. It has crimsom red eyes, eight heads and eight tails (also depicted to having trees and vines growing around them) and has the power of the Demon world, a symbol of evil. Each head of Yamata no Orochi represents a symbol: Soul, Ghost, Evil, Devil, Monstrous, Kill, The Afterworld and Death. Its powers were originally weak, the members of the Kusanagi clan, when attacking it, acted carelessly, using the legendary sword Kusanagi no Tsurugi (Orochimaru’s sword). Because of that, as a consequence, Yamata no Orochi takes the sword from them, absorbing the power contained inside, and becoming an incredibly powerful creature, and finally storing it in its body. With the new power, Yamata no Orochi releases an insane amount of dark energy, awakening the other Bijuu and becoming arrogant. Yamata no Orochi proceeds to defeat many of the Bijuu, but when it battles with Kyuubi, it is defeated. The cause of this is simple: Kyuubi has an unlimited amount of power, making even a hole in the Kusanagi sword. As this happens, it shows how tremendously powerful Kyuubi is, deserving of the “King of Bijuu” title. Not even Sarutobi and Enma (I’m not sure how those two are into the legend) could scratch the Kusanagi no Tsurugi. (That makes connections to the Orochimaru x Sandaime battle) Legend also depicted it as having a power able to rival Kyuubi’s [in quality], but the fact is, Yamata no Orochi’s does have a limit.
Situation in the Ancient War of the 9 Gods: Battled 5 times; 4 Wins, 1 Losses
Wins: Shukaku, Isonade, Kaku, Raijuu
Losses: Kyuubi
Fate: Yamata no Orochi awaits a genius of the Yagami clan, which is the arch enemy of the Kusanagi clan. The purpose is to awake it [Yamata no Orochi], in order to fight Kyuubi again. Since Yamata no Orochi’s power inherits in the Yagami Clan, If the heir appears as the first genius in 1000 years that is able to awake Yamata no Orochi’s ability, it will be completely restored. Once the process is done, the genius with such crucial task will be destroyed due to the true body of Yamata no Orochi resurfacing, which has an all-new power. It won’t be found before the decisive battle with Kyuubi, and will be able to kill no matter of thing, destroy any type of place, and attain infinite vision (as Kyuubi has). The core of Yamata no Orochi’s power is in a kind of forbidden sealing jutsu. As soon as the Yagami clan heir comprehends enough of it, a bigger, much stronger power will surface in the grasp of Yamata no Orochi.
Japanese Myth Appearance: A super Snake of Eight heads and Eight tails, attached to a single body. Has a deep brown color. It definitely is the biggest bijuu - the lenghth of it is over eight mountains. Originally, it was weaker than Houkou and Nekomata; however, that was 1000 years before a brave warrior tried defeating it with the Kusanagi no Tsurugi. In the process, the sword’s power is absorbed instead by Yamata no Orochi, thus greatly expanding his power. He continues though to be able to use freely the sword in his belly.
Ability: The legendary sword: Kusanagi no Tsurugi; summoning of evil spirits
Bijuu Strength Ranking: 2nd
Bijuu Chakra/Stamina Ranking: 2nd
Symbolic Element: Devil
Origin / Discovered in: An old battlefield in Osaka
More info about Yamata no Orochi:
There is the story of the killing of the Eight-Headed Serpent by Susanoo. According to the legend, a local town had been living in fear of the Serpent, and the townspeople offered the sacrifice of a young girl each year to keep it appeased. Lord Susano heard about the town's dilemma, and became determined to slay the beast. He exterminated the serpent by serving it alcohol, and then cutting off its heads while it was intoxicated. Between the Kagura performances, this one is the most famous.

Name:Kyuubi Yoko or Nine-Tailed Demon Fox
Jinchuuriki: Uzumaki Naruto
Tale in the Legend of the Tailed Beasts: This is a bijuu in the shape of a nine-tailed fox, and the strongest of them all. The reason he is so powerful is simple: Kyuubi has an unlimited amount of power, earning it the “King of Bijuu” title. The power is generated by Kyuubi’s Fire Seal, and as a result, after battling for 100 years with Yamata no Orochi, it becomes exhausted; but Kyuubi continues standing, able to fight. It is also pretty cunning and smart.
Situation in the Ancient War of the 9 Gods: Battled 4 times; All of them victories
Wins: Nekomata, Houkou, Raijuu, Yamata no Orochi
Fate: In unclear whereabouts, Kyuubi continues to kill all the people on his way to find the one who awakened him, and the one who managed to seal him before. (That being Yondaime, probably) Yamata no Orochi didn’t tell Kyuubi, though, that the one who awakened him was the Eight Tails himself.
Japanese Myth Appearance: Kyuubi Yoko is the strongest (S Level) Bijuu of the Japanese Myth. Its body has a red fur; Kyuubi represents the element of Fire. Its abilities are incredible. Because it has never been defeated by any youkai, its total strength is unable to estimate. His tails create cyclones by spinning quickly, and Kyuubi proceeds to rip its enemies with its huge claws. At the same time his fur may shoot fireballs similar to meteorites endlessly, instantly destroying villages. In the ancient Bijuu wars, a challenge results in Houkou being severely wounded, and Nekomata nearly dying, but ending up being rescued by his master, Shinigami (God of Death). Yamata no Orochi depended on the Kusanagi no Tsurugi to fight Kyuubi, but was defeated and the sword received a cracked hole, courtesy of our kitsune.
Ability: Fire element attacks, Flaming claws, and other things depicted above
Bijuu Strength Ranking: 1st
Bijuu Chakra/Stamina Ranking: 1st
Symbolic Element: Fire (God of Fire)
Origin / Discovered in: Hidden Altar of Gods in Kobe
More info about Kyuubi:
The Kyuubi is an intelligent demon that is capable of speech and has a scathing, sadistic personality. However
he has also a sense of fairness and sarcastic honour, as he sometimes helps Naruto when he is in a difficult situation. This could be for purely selfish reasons, however, for it is speculated that if Naruto dies, then the Kyuubi will die with him. It seems likely that the Kyubi has some concept of a loathing respect for Naruto and even more so for the Yondaime Hokage.
like the tanuki (racoon), the fox has long been considered an animal possessing supernatural powers, but the fox is less amusing than fearsome. stone foxes are often found at the entrance to shrines venetrating Inari, the guardian god of cereal crops. in the medieval times, the white fox was believed to be sacred, and it came to be regarded as god's messenger.

That's it for everyone!
