Well, a great plot for 'Eight Gates Naruto Fanfiction' could be about a young ninja from a small village who idolizes Rock Lee and his use of the Eight Gates. This ninja tries to learn the technique secretly but faces many difficulties. As the story progresses, Naruto discovers his efforts and decides to help him train properly. It could also explore how the Eight Gates affect a ninja's body and mind in more detail than the original show, like what happens when a ninja tries to open a gate without proper training.
Maybe a fanfiction where an older Naruto, who has mastered the eight gates, passes on his knowledge to a new generation of ninjas. The story could focus on the challenges the students face in learning such a dangerous and powerful technique, and how Naruto helps them overcome their fears and limitations.
One idea could be exploring what would happen if a new character mastered the Eight Inner Gates in a unique way. For example, instead of using it just for combat, they use it to enhance their medical ninjutsu, being able to heal more quickly or even perform impossible surgeries by supercharging their chakra control with the gates. Another idea is a time - travel fanfic where a character from the future comes back to train the early Naruto characters in the proper use of the Eight Inner Gates, changing the course of many battles.
One plot twist could be that the person who was thought to be teaching Naruto about the eight gates was actually a spy from an enemy village. They were trying to get Naruto to overuse the eight gates and destroy himself so that Konoha would be weakened. But Naruto figures this out just in time and uses this knowledge to turn the tables on the enemy.
One idea could be a story where a new character discovers the power of the Celestial Gates and has to learn to control it while facing off against powerful enemies from the Naruto universe. Maybe they accidentally open too many gates at once and have to deal with the consequences.
Another concept could be a story set in an alternate universe where the Eight Celestial Gates are not just physical techniques, but also have a spiritual connection. Naruto, in this universe, has to go on a spiritual journey to fully master the gates and in the process, he learns more about the history and secrets of his ninja world.
One interesting idea could be exploring the limits of the 8 gates beyond what was shown in the original Naruto series. Maybe a character unlocks a new level of power within the 8 gates that no one has ever seen before.
One idea could be a story where a new character discovers a hidden ninth gate within the Eight Inner Gates system. This character, inspired by Naruto's determination, attempts to master this gate while also facing off against old enemies who want to use this power for evil.
One idea could be a story where a new character discovers a hidden power related to the Nine Gates that was lost in history. They then have to learn how to control it while facing off against old Naruto villains who also want this power for their own evil purposes.
In fanfiction, if Naruto became the master of the eight gates, he would be extremely powerful. His already formidable combat skills combined with the power of the eight gates could make him nearly unbeatable. He could use this new ability to protect Konoha in ways he couldn't before. For example, in battles against powerful foes like Madara or Kaguya, he could open the gates one by one to gain more power and surprise his enemies.
A plot could revolve around a young ninja who has a natural affinity for the Eight Inner Gates but is from an outcast clan. Naruto takes this ninja under his wing. They train together, and the young ninja gradually unlocks new levels of power within the gates. However, this new power attracts the attention of a powerful and jealous ninja from another village who wants to steal the secret of the gates for themselves. This leads to a series of battles and challenges.
