One interesting story could be about the two - tails jinchuriki's journey to control the beast's power. Maybe they face a powerful enemy and have to learn to use the two - tails' abilities in a new way to defeat them.
Often, other Naruto characters like Naruto Uzumaki or Kakashi Hatake might be included in the two - tails jinchuriki fanfiction. Their interactions with the two - tails jinchuriki can create new and exciting plotlines, whether it's them helping the jinchuriki control their power or going on adventures together.
Yugito Nii is a very popular character as she is the actual 2 - Tails Jinchuriki in the Naruto series. In fanfiction, she often takes center stage, whether it's in stories about her training or her battles against powerful foes.
One idea could be the six - tails jinchuriki's struggle to control the power. For example, they constantly have to battle the inner urge of the six - tails to go on a rampage. Another plot could involve the jinchuriki being hunted by an evil organization that wants to extract the six - tails' power for their own malicious use. They would then have to fight and outwit this organization while also dealing with the social ostracism that often comes with being a jinchuriki.
In certain fanfiction, Naruto is indeed the Ten - Tails. This could be a really cool concept as it combines Naruto's already powerful nature with the ultimate power of the Ten - Tails. It might lead to stories where Naruto has to struggle with the dark side of such power, or he could use it to bring about a new era of peace in the ninja world. Maybe he would have to face off against old enemies who are now even more afraid of his new - found strength.
One idea could be exploring the relationship between the 2 - Tails Jinchuriki and the other Jinchuriki in the Naruto world. Maybe they form an alliance to protect themselves from those who would use their power for evil.
Sakura could be a great choice. She has strong medical ninjutsu skills and a no - nonsense attitude. She could help the six - tails jinchuriki when they get injured during battles against the power of the six - tails or external enemies. Also, her growth as a character could be further explored as she tries to understand and support the jinchuriki.
When Naruto is the Ten - Tails in fanfiction, there are several implications. Firstly, his physical and chakra abilities would be off the charts. He could potentially have new jutsu or techniques that are exclusive to the Ten - Tails' power. Secondly, the story's plot could revolve more around Naruto's internal struggle with the power. He might have to fight the urge to let the power corrupt him. And thirdly, the political situation in the ninja world would change. Villages might either try to ally with Naruto or plot against him out of fear of his new - found might.
Another cool plot twist could be that the Ten Tails has the ability to split into multiple smaller entities, each with its own unique power. This would force Naruto and his friends to come up with new strategies to deal with these new threats. And it might also lead to some of these smaller entities turning good and helping Naruto in unexpected ways.
Well, it could be about Naruto somehow having to control or deal with the power of the Ten - Tails. Maybe he has to fight an enemy who also wants to harness that power.
