Well, perhaps it's because the Naruto universe has such a distinct and complex world - building. When it comes to crossovers, it's difficult to blend it seamlessly with other universes. For example, if you cross it with a modern - day superhero universe, the differences in power systems, cultures, and values are huge. This might make the crossover fanfiction seem forced or not as appealing, leading to it being neglected.
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.
One example could be a crossover where Naruto is neglected in a world of Fairy Tail. Maybe Naruto is transported there but because he doesn't have the same type of magic as in that world, he's initially overlooked and neglected. Another could be a Naruto and Bleach crossover where Naruto's unique skills are not recognized at first, leading to his neglect. There could also be a crossover with One Piece where Naruto's ninja abilities seem out of place and he's not given much attention at the start.
One interesting aspect could be the unique character development. When Naruto is 'godlike', it can lead to new power dynamics and relationships in the crossover. For example, he might interact with characters from other universes in ways that are not possible in the original Naruto storyline. This can create exciting new plot twists and story arcs.
One possible plotline could be Naruto finding a new family in the crossover world. For example, if it's a crossover with the Harry Potter universe, he might be taken in by the Weasley family who see his potential and give him the love and support he never had in his own family. Another plotline could be Naruto using his skills to prove his worth to his neglectful family after being influenced by the new world he's in. He could return to his own world with newfound confidence and make them realize what they missed out on.
One interesting plot could be where the neglected and dark Naruto is thrust into a crossover with another anime world, like Bleach. He could use his new - found darker powers to fight Hollows, and his experiences of being neglected could add depth to his character as he tries to find his place in this new world. Maybe he forms an unlikely alliance with a Soul Reaper who also has a troubled past.
Well, it's popular because it offers a fresh take on Naruto. We are so used to seeing him as a hero in his own universe. But in these crossovers where he's neglected, it gives a sense of vulnerability. It also appeals to fans who want to see how Naruto would interact with different characters and cultures in other fictional worlds. When he's neglected, the interactions become more complex and full of potential for interesting storylines. Plus, it can be a way for fans to insert their own ideas about how Naruto should handle difficult situations, especially when he's not in his comfort zone of being a respected ninja in Konoha.
One reason could be that other characters might be more popular among fanfiction writers. For example, if there are more glamorous or complex characters in the same universe, they might overshadow Percy. Another reason could be that the storylines involving Percy are not as easy to explore in fanfiction. Maybe his character arc in the original work is so straightforward that it doesn't offer much room for creative reinterpretation.
Perhaps there are family secrets or misunderstandings. His family might have some hidden agenda or past issues related to Naruto's brother that make them focus more on him. It could also be that Naruto's brother is seen as more compliant with the family's traditions and expectations, while Naruto is more of a free - spirit, which causes the neglect.
A great 'Naruto neglected crossover fanfic' idea could involve a crossover with the 'Dragon Ball' universe. Naruto's power - ups and his will to protect his friends could be put to the test against the super - powerful Saiyans. He might learn new ways to harness his energy from Goku and the others. And there could be some really epic battles. Another possible crossover could be with the 'One Piece' world. Naruto's journey to become Hokage could be compared to Luffy's journey to become the Pirate King. His crew - like relationships in Konoha could also be explored in relation to Luffy's Straw Hat crew.
One reason could be that his siblings have some special abilities or talents that overshadow Naruto. In the ninja world, those with unique powers often get more attention. So, if his siblings possess something extraordinary, Naruto might be pushed to the side.
