It could make some characters more sympathetic towards him. For example, if Harry Potter were to find out in the fanfiction, he might start to see Snape in a different light, realizing that Snape has his own deep - seated problems. This could potentially lead to a more complex and nuanced relationship between them.
In such a fanfiction, Naruto keeping to himself might make others initially find it hard to approach him. For example, his friends like Sasuke and Sakura might be a bit confused at first. Sasuke, who is also a bit of a loner in his own way, might not know how to deal with this new Naruto. Sakura, on the other hand, might try harder to break through his shell. This could lead to some strained relationships at the start, but as the story progresses, those who truly care about Naruto would try to understand him better and build deeper, more meaningful relationships with him.
With Hermione Granger, Snape might see her as a threat to his new - found power. Hermione's intelligence and thirst for knowledge could be a problem for Snape as the Dark Lord. He might try to either recruit her or eliminate her, and Hermione would be in a constant battle of wits with him.
If he changes to a more approachable look, like wearing lighter colors and having a more open expression, his relationship with his students could improve. They might be less intimidated and more willing to ask him for help. For instance, Neville Longbottom could finally feel comfortable enough to approach Snape for extra Potions lessons.
One possible reason could be his self - loathing. He has a complex past and has made many difficult choices. In fanfiction, the authors might explore his inner turmoil through self - harm as a way of expressing his pain. He may feel that he doesn't deserve any better because of his actions and mistakes.
His relationship with Sasuke could be really interesting. Sasuke, who has his own complex view of the world, might see Naruto's new behavior as either a sign of weakness or a new strength. If he views it as a weakness, he could use it to taunt Naruto. But if he thinks it's a strength, it might make him more curious about Naruto and what he's discovered. This could lead to a new dynamic in their relationship, either more competitive or more collaborative depending on how Sasuke interprets Naruto's act of eating raw meat.
In romantic relationships in fanfiction, Snape can be quite badass. He might be very guarded at first, not easily giving in to his feelings. But when he does, he's all in. He'll protect his love interest from any danger, whether it's from dark wizards or from the prying eyes and gossiping tongues of Hogwarts. He uses his skills and knowledge to keep them safe, and if anyone tries to come between them, he'll use his wit and magic to drive them away.
In certain fanfictions, the izuku system is a secret. This secrecy can strain his relationships as he has to constantly lie or be evasive about his sudden improvements. But when the truth comes out, it can either lead to a huge rift or a deeper understanding among his friends, depending on how the writer chooses to portray it.
His relationship with his sensei, like Kakashi, could become more complex. Kakashi would feel guilty for not being able to protect Naruto from the experiments. And Naruto might start to question Kakashi's ability to keep him safe. This could lead to a strain in their relationship at first, but later they could grow closer as Kakashi helps Naruto recover from the trauma of the experiments.
Well, Snape has always had a complex relationship with Harry. When he finds Harry cutting himself in this fanfiction, he might be angry at first, thinking it's a sign of weakness. But then, as he realizes the depth of Harry's pain, he could soften. He might start to see Harry more as a troubled child rather than just James Potter's son. Snape could use his knowledge of potions to create something to heal the physical wounds and also try to offer some form of emotional support, albeit in his own gruff way.
If Snape was an Animagus, it could make his relationship with Harry even more complex. Harry might be initially distrustful of Snape's Animagus form, seeing it as another way for Snape to spy on him. However, as time goes on, he might come to understand that Snape's Animagus ability is also used for other purposes, like protecting Hogwarts in a different way.
