No. Naruto does not lose the Nine Tailed Demon Fox
Honestly i dont remmber how many tails he has had but if possible he can get all 9 tails but then the fox demon has utter control over naruto or is possibly unleashed.
Naruto`s father Minato shows up in Naruto manga 439 when naruto i close to release the 9 tails.
No, the 4th hokage/Naruto's dad, SEALED the demon in Naruto which kills him,that's why Naruto was so lonley anywho, it's physical body is gone, but it spirit still rages on(inside of Naruto).
Naruto first encounters the Nine-Tails Fox within his own subconscious mind. This happens during his fight against Mizuki in the Forest of Death. Naruto accidentally taps into the fox's power and begins to manifest the fox's chakra, catching the attention of his inner beast.
There are nine versions of the Kyuubi [Nine Tailed Demon Fox] since it has 9 tails and Naruto, so far that I've seen, can summon up 4 but then he goes way out of control!
he has a demon fox inside of his that whats to live he will die from overusing demon fox chakra.
To protect the leaf village...Minato sealed the fox in naruto
Naruto has the nine tailed fox demon sealed inside of him. In later episodes, they usually refer to it as a chakra monster.
Kyuubi or Kyubi is the nine tailed demon fox from Naruto; he (it) possesses Naruto himself. ^^
It almost did when Naruto was in 8 tailed form while fighting with God Realm Pain. Naruto ,while in 8 tailed form was uncounciusly talking with the Demon Fox. The Demon Fox persuade naruto on taking off the seal and Naruto almost take it off, that's when his father, the 4th Hokage appear as a memory and pull naruto away from the Demon Fox and tell naruto that he is his father and tell him stuff about the time when the Demon Fox attack Konoha. For more info read Naruto manga chapter 440 - 441.
The three toughest characters in the Naruto series to date are Nagato (controler of the Pains; leader of Akatsuki), garra,of the desert (Tobi), and Naruto Uzumaki when in sage mode and in his demon-fox form (so far he has only grown up to six tails so with the pattern increasing the power when he uses all nine tails will be the power of the fox itself, making Naruto invincible for the time he is in that mode.)
