In some 'naruto acts cruel' fanfictions, Naruto might be depicted as being overly harsh in battle. For example, instead of showing his usual mercy, he could be written to use excessive force on opponents who are already defeated. This could be a way for the author to explore a darker side of Naruto's character, perhaps influenced by some extreme circumstances in the fan - created plot.
Well, sometimes in such fanfiction, Naruto may act cruel towards his friends. Maybe he's been deceived or brainwashed. For instance, he could lash out at Sakura or Sasuke in a way that's completely out of character for the original Naruto. It's a shock value thing that some fanfiction writers use to create a more edgy and different story line from the original series.
In some Naruto fanfictions, a cruel act could be Orochimaru performing even more inhumane experiments on his subjects. He might use innocent villagers or captured ninja in ways that are more extreme than in the original story.
One example is 'A Clockwork Orange'. It has very cruel and disturbing scenes, with the main character and his gang committing violent and immoral acts. Another is 'The Road' which shows a post - apocalyptic world full of cruelty and survival at any cost.
One example could be 'A Clockwork Orange' by Anthony Burgess. It has scenes of extreme violence and a rather unusual take on the concept of free will and conditioning, which some might consider cruel in its portrayal of the main character's actions and the society's response to him.
It can also break characters' spirits. Consider Sasuke in a fanfic where he endures continuous cruel acts. He could become completely desolate and lose all hope, which is different from his complex and somewhat hopeful character in the original story.
The story of Medgar Evers' assassination and the subsequent pursuit of justice can also be seen in a way as related to acts of vengeance, but in a more positive sense. After his unjust killing due to his civil rights activism, there was a strong push for justice which was like a form of vengeance against the wrongdoers in the form of legal prosecution.
The Rwandan Genocide is also an act of violence based on a true story. In 1994, ethnic tensions led to mass killings. Hundreds of thousands of Tutsi people were brutally murdered by Hutu extremists. This event has left deep scars on the nation and the international community has since been more vigilant about preventing such ethnic - based violence.
Maybe there's a curse placed on Naruto that slowly turns him into someone with Urahara's personality and abilities. As he transforms, he has to hide it from his friends at first. But as time goes on, they start to notice the changes. He then uses his new Urahara - like self to uncover the mystery behind the curse and who cast it. It could also be that Naruto meets a spirit that infuses him with Urahara - like qualities as a test. He has to prove that he can use these qualities for good in the ninja world.
I'm sorry, I'm not aware of specific 'acnologia is naruto fanfiction' examples off - hand. You could try searching on fanfiction websites like FanFiction.net or Archive of Our Own using relevant keywords to find such stories.
Some examples could be stories that focus on Naruto having a different jutsu system based on the prototype. For instance, if in the prototype he had a more nature - based jutsu instead of the shadow clone jutsu. Another example might be fanfictions that explore the relationships between characters like Sasuke and Naruto in a way that was different in the prototype, maybe they were friends from the start in the prototype and the fanfiction elaborates on that concept.
Well, Naruto in fanfiction often acts like a ninja in terms of his stealth. He might be able to blend into the shadows of the forest so well that even the most experienced ninja have trouble detecting him. And when it comes to intelligence gathering, he could use his charm and friendly nature to get information from villagers or even other ninja without them realizing they are being pumped for intel. Another way is his combat adaptability. He can quickly analyze his opponent's fighting style in a fanfiction battle and come up with a unique strategy on the fly, which is a very ninja - like trait.
