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.
They can be a great source of creativity. The lack of attention means the author has more freedom to experiment. They might combine Naruto's ninja world with a post - apocalyptic setting or a fairy - tale world. This gives a fresh perspective on the Naruto character and his abilities.
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.
In a crossover with the DC Universe, Batman could be an interesting character. Batman, who also had a tragic past, could understand Naruto's feelings of being neglected. He could take Naruto under his wing and train him in new combat and detective skills. Another interesting character could be Superman. Superman, with his kind - hearted nature, could show Naruto what a real family should be like, as he has the Kents as his loving family.
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 neglected Naruto crossover swordsman fanfiction could be where Naruto is transported to a world full of swordsmen. In this type of story, he might learn new sword - fighting techniques and combine them with his own ninja skills. For example, he could use his shadow clone jutsu in creative ways during sword battles.
In a Naruto - Inuyasha crossover, the neglected dark Naruto could be shown as having a more brooding and angry demeanor. He might have a bit of a rivalry with Inuyasha at first because of their similar temperaments. His dark chakra could attract demons, and he'd have to learn to control it while also dealing with the feudal Japanese setting and the yokai.
One interesting neglected Naruto crossover fanfiction could be 'Naruto in the World of Bleach'. In this, Naruto is somehow transported to the Bleach universe. It shows how he adapts to the new world, his powers in relation to Soul Reapers and Hollows, and the unique interactions he has with characters like Ichigo. It's a great read for those who like to see their favorite characters in different settings.
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.
It could also be due to some family curse or prophecy. In the Naruto universe, there are often strange powers and curses. Maybe there was a prophecy that said Naruto's family had to keep their distance from him to protect him from some greater evil. So, they chose to neglect him in order to keep him safe, even if it was a difficult choice.
