It gives fans a chance to explore different 'what - if' scenarios. By seeing the Avengers' reactions, fans can get a deeper understanding of the characters.
The Naruto fandom would probably react very negatively. Fans are used to seeing Naruto as a hero, a symbol of hope and growth. A fanfic that portrays him as a slave goes against the very essence of what Naruto represents. There would be a lot of criticism on social media platforms, and many fans might even call for the fanfic to be removed or boycotted.
There would be a portion of fans who are very against it. They are so used to the idea of Sakura and Sasuke being a potential couple that any deviation from that would seem wrong to them. They might feel that it goes against the 'canon' in a way, even though it's a fanfic.
The Naruto fandom would likely be very divided. Some fans might be intrigued by this unique and unexpected plot twist, seeing it as an interesting exploration of an alternate Naruto universe. However, many fans would probably be quite shocked and even appalled, as it goes against the traditional understanding of the characters and the series.
Some fans might be really sad about it. They love the idea of Sasuke and Sakura together as a couple and see their relationship as a symbol of hope and growth. So, divorce fanfiction goes against their ideal view of the couple.
One idea could be a story where a young hero has the determination of Naruto and the combat style of Garou. He could be from a small village that's looked down upon, much like Naruto's Konoha in the beginning. He trains hard, using Naruto - like perseverance and Garou - like fighting instincts to rise through the ranks and prove himself to the world.
Writing a great 'naruto like garou fanfic' is no easy feat. You should start by deciding on the central theme. Is it about redemption like some of Garou's storylines or about achieving a great goal like Naruto? Then, think about the setting. It could be a new world that blends the fantastical elements of Naruto's world with the more gritty and urban feel of Garou's. When creating the characters, give them traits from both Naruto and Garou. For the plot, create a series of challenges that force the characters to use both Naruto - like and Garou - like skills. For instance, they might have to face a moral dilemma like Naruto and then fight their way out of it using Garou's combat skills. Also, don't forget to add some emotional depth to the story, so the readers can really connect with the characters.
