One aspect of this fanfiction could be the exploration of the harsh realities within the Naruto universe. It might show characters being forced to make difficult choices between killing their opponents or being killed themselves. This could lead to a deeper understanding of the moral gray areas that exist in a world full of ninja battles and power struggles.
The high - stakes nature of the 'kill or be killed' concept makes it interesting. It amps up the drama and tension. We see our favorite Naruto characters in life - threatening situations, which makes for a gripping read.
His father, Minato, could be a likely candidate in a really dark fanfiction. Maybe he was resurrected in an imperfect way and his mind was warped, causing him to turn on Naruto.
No. Fanfiction is a form of creative expression. Naruto fans write fanfiction to explore different ideas and stories within the Naruto world. Just because someone doesn't like it doesn't mean it should be 'killed'.
One idea could be that Naruto and Sasuke are somehow transported to the world of Kill la Kill. They might get involved in the fight against the Life Fibers, with their ninja skills being a unique addition. Maybe Naruto's Rasengan could be used to disrupt the Life Fibers in a new way.
There may be some dark or alternate universe fanfictions out there with such a plot, but it goes against the general nature of the Naruto series. Naruto is more about friendship and growth, not about killing main characters like Tsunade in a random way.
Yes, there might be such fanfictions out there in the vast world of fan - created content. However, this goes against the general storyline of the Naruto series where they are comrades.
It could be his own mother. She might realize that he has become too dangerous and, in a moment of heart - breaking decision, find a way to destroy him. Maybe she discovers a weakness and uses it against him, driven by her love for humanity and the knowledge of the destruction he could cause.
It could be a new and powerful dark side user. This character might have emerged from the shadows, having trained in secret, and their sole purpose is to take down Anakin as he is seen as a threat to their plans for galactic domination.
One interesting crossover is when the ninjutsu from Naruto is combined with the combat style of Kill la Kill. For instance, Naruto using his shadow clone jutsu while Ryuko uses her scissor blade attacks in tandem. It creates a very dynamic and visually appealing fight sequence.
