One interesting plotline could be Naruto struggling to master a particular elemental ninjutsu like lightning. He might face a tough opponent who uses lightning attacks, which forces him to quickly learn and adapt. Another could be Naruto learning from an unexpected source, perhaps an old hermit in a far - off land who has a unique way of teaching elemental ninjutsu. It could also involve Naruto combining different elemental ninjutsu in creative ways, for example, mixing fire and wind to create a more powerful attack.
One interesting plotline could be Naruto making unexpected alliances with different clans in the elemental nations. For example, he might team up with a water - based clan and learn their unique water - style jutsu techniques, which he can then combine with his own skills.
One interesting plotline could be the main character's journey to master the elemental dragons. They might face challenges like finding and bonding with each dragon, which has its own unique personality and power. Another could be how they use the dragon's powers in battles against powerful foes in the Naruto universe, like the Akatsuki members.
One great fanfiction could be 'Naruto's Medical Journey'. In this story, Naruto starts learning medical ninjutsu from Tsunade. He faces many challenges as he has to balance his normal training with this new form of ninjutsu. But his determination helps him progress steadily.
In some fanfictions, there are ninjutsu that can manipulate time on a small scale. For example, a ninja might be able to slow down time for a brief moment to gain an advantage in combat. This type of ninjutsu adds a really interesting twist to the battles. It requires a great deal of chakra control and is often only mastered by the most skilled ninjas in the fanfiction world.
Another concept could be a character who is an outcast in the ninja world but has a natural talent for medical ninjutsu. This character could be inspired by Naruto's journey of being an underdog. They might use medical ninjutsu in unorthodox ways, like using it to enhance the physical abilities of other outcasts.
One interesting plotline could be a sorcerer who discovers a new elemental magic that combines two or more existing elements in a unique way. For example, a blend of fire and water to create a steam - based offensive spell.
Well, one common story could be about the character being a ninjutsu prodigy who quickly masters advanced jutsus that others struggle with for years. For example, they might develop a unique way to combine fire and wind jutsus in a more powerful form.
One popular plotline often involves the main character exploring and mastering new elemental sage powers. For example, they might discover a new combination of elements that gives them an edge in battle. Another is the character's journey to find the origin of the elemental sage powers, which could lead to uncovering ancient secrets and forgotten lore.
Jiraiya could be one of his mentors. He's already Naruto's teacher in many ways and has a vast knowledge of different ninjutsu, so he would be a great choice to teach Naruto about elemental ninjutsu. Another potential mentor could be Kakashi. He's known for his wide range of skills and could pass on his knowledge about elements to Naruto. Also, Tsunade might be a mentor. She has great control over her chakra and could teach Naruto how to use his chakra more effectively for elemental ninjutsu.
One idea could be a young ninja who discovers a long - lost scroll on bubble ninjutsu. They start to practice it secretly and use it in unexpected ways during battles, like creating giant bubble shields or using bubbles to carry messages. Another plot could involve a competition where the bubble ninjutsu is the main focus, and ninjas from different clans compete to show off their unique bubble - based techniques.
