One possible plot could be that it causes chaos in the wizarding world. His friends like Hermione and Ron are devastated. They might start an investigation to find out the cause of his death, suspecting dark magic or a hidden enemy. This could lead to a series of adventures as they search for the truth.
Maybe it's a sacrifice. Harry could have died to protect someone or something important. His death could then inspire others to fight against the forces of evil more vigorously. For example, Neville could take up Harry's mantle and lead the resistance at Hogwarts. The story could then focus on how Neville and the others carry on Harry's legacy.
It could be a case of betrayal from within. Maybe someone who was thought to be an ally, like a wizard who was secretly working for the dark side all along. They could have used a powerful and unknown curse to kill Harry in the middle of the night without anyone suspecting them at first.
One possibility could be that Voldemort manages to find and kill Harry much earlier. Maybe the protection spell that Lily cast fails due to some unforeseen dark magic interference. This would change the entire wizarding world. Hogwarts might be taken over by Death Eaters completely, and there would be no 'Boy Who Lived' to inspire hope. The Order of the Phoenix would likely be crushed much sooner, and the wizarding world would descend into a much darker and more oppressive state than in the original story.
One possible plot development could be that his friends are left to pick up the pieces. They might struggle with grief and guilt, thinking they could have saved him. Another could be that Voldemort finally takes over completely without Harry to oppose him, leading to a dark reign over the wizarding world.
One possible plot could be that Naruto is poisoned by a Christmas - themed gift that was actually a trap set by an old enemy. As he slowly succumbs to the poison on Christmas, he reflects on his life and his friends. His friends gather around him, trying to find a cure, but it's too late, and he passes away, bringing a somber mood to the usually festive Christmas in the Hidden Leaf Village.
In the 'naruto dies boruto fanfic', it could be that Naruto is killed by an unexpected betrayal within the village. This shatters Boruto's world. He then goes on a journey to find out the truth behind the betrayal. Along the way, he meets some of Naruto's old friends who help him train and grow stronger. Boruto also starts to uncover secrets about the village's past that his father was trying to protect, and he realizes he has to be the one to expose these secrets and bring justice to his father's death.
Well, in this kind of fanfic, Harry could be neglected by Hogwarts staff. For example, teachers may be too preoccupied with other matters, such as political unrest in the wizarding world. Harry, feeling alone and abandoned, might venture into dangerous areas like the Forbidden Forest more often. He could encounter a powerful and malevolent creature that he's not ready to face, and ultimately die because there was no one to rescue him. Also, the Sorting Hat could potentially mis - sort him into a house where he doesn't fit in at all, and the neglect from his housemates could contribute to his downfall.
If Harry dies in the first task in fanfic, it would completely change the whole story. For one, Hogwarts would lose its hero. The Triwizard Tournament would be thrown into chaos. Cedric might become the sole focus then, but he also would be in shock as Harry was his competitor and also a fellow student. And Voldemort's plans related to Harry would be thwarted, at least for the time being, as he had some long - term designs involving Harry. It would also have a huge impact on Harry's friends, like Ron and Hermione. They would be devastated and might try to find out the real cause of his death.
It could be about a character's unexpected adventure during one night and two days. For example, a fanfic of a superhero who has to deal with a new villain that emerges during this short time frame. The superhero might struggle at first but then discovers the villain's weakness and saves the day.
One possible plot could be that the story focuses on the emotional turmoil of those around Sakura. Her friends and family might be in shock and disbelief as they were expecting a joyous birth but instead are faced with her death. They could struggle with guilt, thinking if there was something they could have done to prevent it.
Perhaps in this fanfic, Naruto's death at the Valley of the End could lead to a new era of power struggles. The other ninja villages might try to take over the Leaf's territory. Meanwhile, Naruto's death could inspire a new generation of ninjas who want to uphold his ideals. They would have to fight against the odds to keep the peace that Naruto once fought for.
