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 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.
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.
A possible fanfiction could be centered around the Jinchuriki's role in a major battle. For example, in a war against an enemy ninja force, the Jinchuriki could unleash Matatabi's power in a strategic way to turn the tide of the battle. They might combine Matatabi's fire - based attacks with other ninja techniques they've learned, like water - style jutsu to create a steamy and powerful defense or offense. Also, their bond with Matatabi could give them an edge in terms of sensing the enemy's moves before they happen.
Gaara is a very likely recipient. He was a Jinchuriki like Naruto and they have a strong bond. Naruto might send him letters to check up on him and continue their friendship.
It could also be a form of building alliances. By reaching out to the Jinchuriki through letters, Naruto is establishing a connection. This can be important in the Naruto universe where having allies is crucial for the safety of the villages and the world at large. He may be hoping to create a united front among the Jinchuriki against common enemies.
Naruto could be one of his allies. Naruto has this knack for seeing the good in people and would probably be willing to give Obito a chance to redeem himself. Also, Sakura, with her skills as a medic - ninja, could be an ally. She might help heal Obito if he was injured during the war and see the potential in him to be a force for good.
First, focus on their backstory. Maybe they were an orphan who was chosen to be the Jinchuriki and had a tough upbringing because of it. This would shape their personality as someone who is both strong - willed but also has insecurities. Second, explore their relationship with Matatabi. They could start by hating the fact that they're a Jinchuriki but as they get to know Matatabi better, they form a unique bond. Third, show their growth in terms of power. Start with them being unable to control Matatabi's power at all and then gradually become a force to be reckoned with.
