naruto father : the 4th hokage
Um...O.o No. Kyuubi is the title of the bijuu sealed inside of Naruto. Naruto's mother was Uzumaki Kushina.
Chapter 299 was the first time Naruto went kyuubi.
There is a Kyuubi Naruto on Naruto Arena. You must complete a certain Mission first. I'm pretty sure it's B-rank.
Kyuubi
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.
the kyuubi is the nine tailed demon fox yodaime sealed within Naruto.
Not necessarily "useless", but he is less powerful without Kyuubi.
you cant
Naruto is NOT Kyuubi! Get this into your head! He and the demon fox are ENTIRELY different! The villagers know that the fox is sealed into Naruto but they treat him as an outcast, not the hero keeping Kyuubi from getting his revenge on Konohagakure no Sato (Leaf Village)
When he is really mad.
The 9-tails or Kyuubi.
you can use an action replay code to get all the characters or you go to the summon sheet put in a code to grt a misson called Extreme Battle where you fight nine tailed naruto(kyuubi naruto) and sasuke in his second form and if you win you get the nine tailed spirit so naruto can turn in to kyuubi naruto in battle.
