In some fanfictions, if Harry Potter sacrifices himself, it could lead to a dark and desolate wizarding world. His friends would be left to pick up the pieces, mourning his loss deeply. For example, Hermione might be driven to find a way to reverse his sacrifice through her vast knowledge, while Ron would be filled with a sense of vengeance towards the forces that led to Harry's death.
In fanfiction, Naruto sacrificing himself for Obito could be a very emotional and dramatic concept. It might show Naruto's ultimate selflessness, believing that Obito is worth saving at the cost of his own life. This could be due to Naruto seeing the good in Obito that others might not, like the part of Obito that was once a kind - hearted shinobi.
When Batman sacrifices himself in fanfiction, it can also be a way to explore the darker side of Gotham. Maybe his sacrifice was in vain, and the city falls deeper into crime and corruption. Or perhaps it leads to a new kind of hero emerging, inspired by Batman's last act. It could also show how the villains react, some might be glad that their nemesis is gone, while others may feel a strange sense of loss as Batman was always a worthy opponent.
One popular fanfic could be 'The Ultimate Sacrifice'. In it, Harry's self - sacrifice is a very emotional and heroic act. He does it out of deep love and friendship for Hermione.
In the fanfic, it could be that Fleur is in a situation where she has to perform a dangerous task to save the wizarding world, like going into an ancient and deadly magical place. Harry, realizing the importance of her mission and also having deep feelings for her (maybe a secret love), sacrifices his own safety by going with her and ultimately giving his life to ensure she can complete the task and save everyone.
If he stabs himself in a non - vital area, he might survive but be severely weakened. This could lead to him having to rely on his friends more for protection and support, changing the dynamics of their relationships.
Peter could sacrifice himself to stop a deadly virus from spreading. He might be a scientist who discovers that his own body can be used to create a cure, but it will cost him his life. So, he decides to go ahead with it to save the world.
It could be due to the trauma he has experienced. Losing friends and facing Voldemort multiple times has surely left deep scars. Isolating himself might be his way of dealing with the post - trauma stress. He needs time alone to heal and come to terms with everything that has happened.
No. The Harry Potter series is aimed at a wide range of audiences, including children and young adults. Such a concept is inappropriate and goes against the values of the original story which promotes friendship, courage, and the fight against evil.
Perhaps in the fanfiction, Naruto gives his life energy to Boruto to save him from a deadly curse. Boruto then has to deal with the newfound power within him, which is a mix of his own and his father's. He may struggle to control it at first but eventually learns to use it for good. This could also lead to a rift between Boruto and some of the villagers who blame him for Naruto's death.
