Well, if Naruto was raised by Slenderman in fanfiction, it would be a wild departure from the original Naruto story. Naruto would likely grow up with a lack of the normal human connections he had in the original. He might be more solitary and his view of the world could be shaped by Slenderman's otherworldly existence. His idea of 'home' or 'family' would be completely different, and this would surely impact how he approaches his ninja duties, if he still has any in this strange new scenario.
In such a fanfiction, Naruto might have a very different personality. He could be more eerie and detached, influenced by Slenderman's strange nature. His ninja skills might also take on a darker, more unpredictable edge.
If Naruto was raised by Slenderman in fanfiction, it would be an extremely interesting and unique concept. Naruto's values would be completely different. Instead of the values of hard work and friendship from the original series, he might value secrecy and the unknown, like Slenderman. His appearance might also be affected, perhaps having a more shadowy or mysterious look. His relationships with other characters, like Sasuke or Sakura, would be non - existent or very different. He might not even be part of the Hidden Leaf Village but exist in some sort of liminal space under Slenderman's influence. And his powers? They could be a blend of his natural ninja abilities and some strange, Slenderman - like powers that are hard to fathom in the context of the Naruto universe.
In such a fanfiction, Harry might grow up with a very different set of values. Slenderman is often depicted as a creepy and somewhat malevolent figure. So Harry could be isolated from normal society. He might be trained in skills that are not typical for a regular upbringing, like how to move stealthily or sense danger in an uncanny way.
Well, in such a fanfiction, Naruto might learn different skills. Maybe he'd be trained in the Hyuuga's Gentle Fist style. This could make him a more versatile fighter, combining his own Uzumaki tenacity with the precision of the Hyuuga techniques.
In such a fanfiction, Naruto might grow up with a very different set of values and skills. Sephiroth is a complex and often dark character from Final Fantasy. Naruto could learn combat techniques that are far more ruthless compared to the ninja way. He might also develop a more solitary personality, as Sephiroth is not exactly a team - player. And his view of the world could be shaped by Sephiroth's own jaded perspective, leading to a Naruto who is less idealistic about the ninja world and more focused on power and self - preservation.
In this fanfiction, Naruto might gain unique abilities from the elves. For example, he could learn their magic or have enhanced senses like the elves. He may also develop a different personality, influenced by the peaceful and nature - loving ways of the elves.
In this kind of fanfiction, Naruto might grow up with a very different set of skills and values. He could be more attuned to the Uchiha's Sharingan - related techniques. Maybe he'd be more brooding like the typical Uchiha, instead of his usual energetic self. Also, his relationship with Sasuke would be really interesting, as they would be more like brothers from the start rather than rivals.
The story could also explore how Naruto's relationship with other characters in the Naruto universe would be affected. His friends like Sakura and Kakashi might be initially suspicious of Sasori's influence on Naruto. But as Naruto shows that he still holds onto his core values, they might come to accept this new situation. And Naruto's enemies would likely be more cautious, seeing that he has new abilities and a different kind of mentorship under Sasori.
In the 'Naruto raised by Shinigamis' fanfiction, Naruto's personality could be quite different. Since Shinigamis are often associated with death and judgment, Naruto might have a more solemn side. He could also have a different view on life and the ninja world. His training would probably be very different from what we see in the original Naruto series. Instead of learning from the traditional ninja senseis, he would be under the guidance of Shinigamis, which could lead to him developing skills that are completely new to the Naruto universe.
In a 'Naruto raised by Kenpachi' fanfiction, Naruto would likely become a much more aggressive and battle - hungry ninja. Kenpachi's fearless and combat - loving nature would rub off on Naruto. He might develop a more straightforward and brute - force approach to fighting, rather than relying so much on his shadow clones.
In such a fanfiction, Naruto might become extremely powerful at a young age. Kurama could teach him unique jutsu and survival skills. He would also likely have a very different view of the tailed beasts compared to canon Naruto.
In the 'naruto raised by izuna fanfiction', Naruto's entire upbringing would be transformed. Izuna, being from the Uchiha clan, would likely introduce Naruto to a world filled with Uchiha traditions and secrets. Naruto might learn to control his chakra in ways that are more in line with Uchiha methods. His social circle would also be different. Instead of growing up with the likes of Iruka and the other villagers, he would be surrounded by Uchiha members. This could lead to a different perception of the outside world for Naruto. He may not have the same drive to become Hokage in the traditional sense, but rather focus on uniting the Uchiha and the rest of the village in a new way, influenced by Izuna's own dreams and ideals.
