The power of teleportation is also quite interesting. In a Naruto fanfiction, a character with this power could instantly move from one location to another, whether it's across the village or to a far - off battlefield. This would be a great advantage in both combat and rescue missions. They could surprise their enemies by suddenly appearing behind them or quickly reach an ally in need. It would also change the way battles are fought as they could dodge attacks by teleporting away at the last moment.
In some fanfictions, Bella has the power of invisibility. This power gives her an edge in spying or sneaking around. She can observe her enemies without being detected, which is very useful in a world full of danger like the vampire world. She might use this power to uncover plots against her family or friends.
Another idea is that Kaneki is brought to the Naruto world by Orochimaru. Orochimaru, being interested in Kaneki's unique physiology, wants to study him. Kaneki has to escape from Orochimaru's clutches and teams up with Naruto and his friends. Along the way, they discover that there are some dark secrets in the Naruto world that are related to Kaneki's past in a strange, unexpected way.
Some fanfictions might give Naruto the power of elemental fusion. He could combine fire, wind, water, earth, and lightning in ways that are not possible in the original series. This would make his attacks extremely powerful and unpredictable. For instance, he could create a storm of lightning - infused water that not only electrocutes his enemies but also drowns them.
One interesting storyline could be Dark Naruto using the Rinnegan to reshape the ninja world according to his own dark vision. He might start by taking over hidden villages one by one, using the powers of the Rinnegan like the ability to summon powerful creatures or manipulate gravity. Another could be his interaction with other powerful characters. For example, how he would deal with Sasuke, who has his own set of powers and goals. It could lead to epic battles and power struggles.
A great crossover could involve the ninja clans of Naruto in the world of Game of Thrones. The Uchiha clan's Sharingan ability might be compared to the prophetic dreams some characters in Game of Thrones have. Maybe the Uchiha could use their powers to foresee battles or political upheavals. And the Hyuga clan's Byakugan could be used for surveillance in the castles and cities of Westeros, much like how the maesters keep an eye on things. Also, the concept of chakra could be introduced to the world of Game of Thrones, where it might be seen as a new form of magic.
One interesting plot could be Naruto mastering a new and extremely powerful genjutsu that even the strongest shinobi can't break. He might use it to defeat a great enemy that was thought to be invincible. Another could be Naruto using his genjutsu god - like powers to enter the minds of his friends and heal their inner traumas.
There's also a plot where Madara and Naruto are the only two people left in a post - apocalyptic shinobi world. They must rely on each other to survive and in the process, they discover new aspects of themselves and their powers. This plot is full of action and also explores their emotional connection in a desolate setting.
In Naruto reincarnation of Kaguya fanfiction, there could be a plot where Naruto discovers that he has the ability to open new dimensions like Kaguya did. This would give him an edge in battles but also attract unwanted attention from other powerful forces. Also, the story could revolve around Naruto trying to understand Kaguya's true motives for creating the chakra system. By doing so, he might find a way to make the shinobi world a better place, perhaps by redistributing chakra more fairly or something similar.
Perhaps a plot where Naruto is influenced by an evil godlike entity. This entity could be from a different dimension. It whispers dark thoughts into Naruto's mind, gradually turning him against the values he once held dear. As a result, he starts to perform actions that are completely out of character for the original Naruto, like attacking innocent villages to gain more power.
A possible crossover could involve the corruption aspect. The Shinju in Naruto has been associated with negative forces and power - hungry individuals. In Gotham, there is also a lot of corruption. Batman is constantly fighting against it. A fanfiction could show how the Shinju's influence might seep into Gotham, corrupting some of its inhabitants, and how Batman tries to stop this new form of evil. He might even have to team up with Naruto characters who understand the Shinju better to save the city.
