Chakra is believed to be real but no the tails chakra isn't real.
The nine tail fox chakra is very immense but it does not have an infinite supply.
No Gaara doesn't have the red chakra. Naruto has it due to the fact that the nine tails is sealed in him. And even if Shikaku (One Tail) did have red chakra Gaara wouldn't be able to use it because the Akatsuki extracted the one tail from him.
no, no matter what he can't get that power due to the death reaper seal his father used, half of the nine tail's chakra will remail forever in battle with the fourth hokage.
No they are not they are only fiction.
The 4th Hokage, Minato Namikaze, Naruto's father told Naruto that when he fought the nine tailed fox he felt that someone is controlling it and when he felt Tobi's chakra while in Naruto's. He told Naruto that it's the same chakra he felt while fighting with the nine tailed beast.
Naruto power when he has a chakra tug o war with kurama (nine tails) and won
Yes, Naruto becomes stronger without using the Nine Tails Chakra. After hearing what he did to Sakura when he was transforming into the Nine Tails, he swore to not use the Nine Tails Chakra unless he really needed to. Instead he undergoes instense training to become stronger and learns new techniques that help him later in the series.
Yeah it has unilimited chakra that's why Its the strongest bijuu
no
Probably not.
yes it is
well The Nine-Tails' chakra usually comes to Naruto during life-threatening or other stressful situations, given to him by the Nine-Tails itself to ensure its survival. Naruto eventually learns to contact the Nine-Tails and demand some of its chakra, which it seems to comply to out of amusement. The reason Naruto is able to access its chakra is because of the unique way in which it was sealed. Though the Nine-Tails remains trapped within Naruto, its chakra can leak out through the seal and mix with Naruto's. The Nine-Tails' massive supply of chakra becomes an invaluable weapon for Naruto, often turning the tide of a difficult battle in his favor. Though useful, expanding the magnitude of his other abilities, Naruto cannot handle too much of the Nine-Tails' influence. As he draws upon additional amounts of the Nine-Tails' chakra, "tails" are produced, and from the fourth tail onwards he is reduced to animal instincts, no longer being able to differentiate between friend and foe. Although he usually stops himself from getting too far, once the fourth tail is attained, he needs outside assistance to force the Nine-Tails' influence to recede. Naruto has at least some understanding on how the seal that keeps the Nine-Tails trapped inside him works, as he is able to manipulate it willingly after receiving its key. Since Naruto has separated the Nine-Tails' chakra from its will, and imprisoned the Nine-Tails itself into a new seal, it is unknown how its chakra will affect Naruto in the future.
