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.

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.

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.

Focus on unique character development. Instead of just having the main characters, introduce new and interesting side characters related to the Eight Inner Gates. For example, a hermit who has been secretly studying the gates for years. Also, add some unexpected plot twists. Maybe the gates don't work as expected in a certain situation, or there's a hidden connection between the gates and an ancient prophecy.

One popular 'naruto learns martial arts fanfic' is 'Naruto's Martial Arts Ascension'. In this fic, Naruto travels to different hidden villages to learn unique martial arts styles from various masters. It's really exciting to see how he combines these new skills with his ninja techniques.

An organization of ninjas who believe that the Eight Gates should be used to create a new world order. They view the current ninja system as weak and want to use the extreme power of the gates to enforce their will. Their leader could be a mysterious figure who has his own reasons for believing in this radical ideology. They would constantly oppose Naruto and his allies who want to protect the balance in the ninja world.

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.
