Kishimoto is very superstitious. The 9 Bijuu come from Japanese mythology.
i think he does, if your not sure type kitsune!
Kyuubi is Japanese word. 'Kyu' means 9 in Japanese. So Kyuubi is 9 tailed
the kyuubi is the nine tailed demon fox yodaime sealed within Naruto.
Not necessarily "useless", but he is less powerful without Kyuubi.
No. Kyuubi strongly resents the fact that the Yondaime managed to seal him.
Chapter 299 was the first time Naruto went kyuubi.
Kurama
Almost everybody
Kyuubi
Om. Probably cause it can hurt others?
Um...O.o No. Kyuubi is the title of the bijuu sealed inside of Naruto. Naruto's mother was Uzumaki Kushina.
Yup. Because of the seal, Naruto doesn't have access to all of Kyuubi power and Kyuubi can easily regenerate all his chakra. He probably has other tricks up his sleeve.
