One common element is the focus on mastering new and difficult jutsu. In these fanfictions, Naruto is often put through rigorous training to learn powerful and unique jutsu that are not part of the original series. This could involve hours of repetitive practice, combined with dangerous sparring sessions to test the new skills. There's also the element of isolation in some of these stories. Naruto might be sent to a remote location for training, away from his friends, to fully concentrate on his development.
Well, Naruto is at the core of these fanfictions. But there are others too. Rock Lee can be part of it. His own training methods, which are based on extreme hard work, can inspire the kind of brutal training Naruto might go through. Also, Orochimaru might be involved in some darker - themed fanfictions. He has his own motives and his knowledge of forbidden jutsu could lead to some really intense and dangerous training scenarios for Naruto, although this would be in a more morally ambiguous kind of story.
There might be fanfiction where Naruto himself has to become brutal in order to protect his loved ones. For example, he might be forced to make some really tough choices, like sacrificing the safety of a few to save the many, which goes against his usual kind - hearted nature. This internal struggle and the external actions that follow could be part of a 'naruto is brutal fanfiction'.
Well, in certain fanfiction about the Chunin Exams, Naruto could be seen as brutal because he might take advantage of his opponents' weaknesses in a rather ruthless way. He may not give them a chance to recover or adjust their strategies. Say, if an opponent is vulnerable after using a big move, Naruto might immediately strike with a powerful counter - attack instead of waiting for a fair rematch. This makes him seem brutal as it goes against the more sportsman - like nature of the regular Chunin Exams.
One common theme is the struggle for power. Naruto has to push himself to the limits to become a brutal fighter, often facing stronger opponents. Another theme is self - discovery. As he becomes more brutal in his fighting, he also discovers new aspects of himself.
In this fanfiction, Hokage Naruto might take Naruto to a special training ground. There, he could teach Naruto some of his own unique jutsu combinations. For example, he could show Naruto how to combine the Rasengan with his Sage Mode more effectively. This would give Naruto a huge power boost and also make him more confident in battles against tougher opponents.
It's a controversial type of fanfiction. In the Naruto universe, Naruto is a symbol of hope and perseverance. To portray him as brutal and bloodthirsty completely subverts the essence of his character. This type of fanfiction might attract those who enjoy exploring dark and alternative versions of characters, but it will also face a lot of criticism from fans who love the original Naruto for his positive traits.
In this fanfiction scenario, Naruto might learn unique chakra control techniques from Sarutobi. Sarutobi, being an experienced ninja, could teach Naruto how to better manage his large chakra reserves. This would lead to Naruto being able to perform jutsus more efficiently and with less waste of chakra.
Perhaps he's been influenced by someone who gives him bad advice. For example, if someone tells him that natural talent is enough and training is overrated. Also, he could be dealing with some personal problems, like a conflict within his family or among his friends that takes up all his time and mental energy, causing him to neglect training.
Well, it could be that the three of them are training Naruto for a big upcoming battle. Temari focuses on Naruto's physical combat skills, teaching him how to better use his speed and strength in combat. Yugito delves into the more spiritual side of chakra, guiding Naruto to connect with his inner power. Naruto, under their tutelage, not only hones his skills but also forms a strong bond with Temari and Yugito. This bond might be crucial in future challenges that Naruto will face in the fanfiction world.
