In fanfiction where Harry Potter dies young, how do the other characters react?

Hermione would likely be devastated. She might go into a deep state of mourning, but also use her intelligence to try and figure out what led to Harry's death. Ron would be angry and heartbroken at the same time. He'd probably want to seek revenge if there was someone or something responsible.

The characters would be devastated. Kurt, being one of her closest friends, would probably be in shock at first. He might go through a period of denial, thinking it's all a cruel joke. Then he would break down and cry, remembering all the times they shared together, from their fashion debates to their duets. He would likely be the one to organize a proper memorial for her, making sure it was as grand as Rachel would have wanted.

Naruto would be extremely devastated. He sees Kakashi as a mentor and father figure. He might go into a period of deep depression at first, but then turn his grief into motivation to become stronger. Sakura would also be very sad and might focus more on her medical skills, vowing to save more lives in Kakashi's memory. Sasuke might have a more internal reaction, feeling guilty if Kakashi died protecting him, and it could further fuel his own goals, whatever they may be at that time.

Hermione would be heartbroken as well. She would likely try to find a way to bring Lupin back, delving deep into the library's restricted section for any possible spells or solutions. She would also be the one to comfort Harry and Ron, using her logic to try to make sense of the senseless loss.

Winry would be heartbroken. She loves Edward deeply. She might initially go into denial and then be filled with anger at the circumstances that led to his death. She could also turn her grief into a determination to help others with her mechanical skills, in memory of Edward.

Sasuke would be deeply affected. He and Naruto had a complex relationship. He might feel a sense of regret for all the times he had pushed Naruto away. His reaction could range from anger at the situation to a new - found respect for Naruto's sacrifice.

Ruby would be devastated. Qrow is her uncle and has been an important figure in her life. She might initially go into denial and then be filled with rage, vowing to avenge his death. She could become more determined than ever to take down Salem, seeing it as the only way to make his sacrifice meaningful.

Lucy would be completely devastated. She and Natsu have a very close bond. She might go into a deep depression, constantly blaming herself for not being able to save him. Gray would be angry at first, feeling like he should have been there to help Natsu. Then he'd be sad and would probably vow to avenge Natsu. Erza would be strong on the outside but inside she'd be broken. She might try to keep Fairy Tail together in Natsu's memory. Happy would be inconsolable, constantly flying around looking for Natsu and refusing to believe he's really gone.

Well, some characters' reactions can be really complex. For example, Dumbledore's portrait might show a solemn look, as if he knew this was an inevitable outcome. The students at Hogwarts would be in a state of shock. Those who were in Slytherin house might feel a sense of loss for their head of house, even if they didn't always understand him. And Neville, he might see Snape's death as a tragic end to a misunderstood hero.

The Hogwarts students would be greatly affected. The younger students who saw Harry as a hero would be in shock. They would lose their sense of safety and hope. The older students who knew Harry personally would feel a personal loss. The teachers, like McGonagall, would be grief - stricken. She had watched Harry grow up at Hogwarts and had seen his potential. His death would make her question the future of Hogwarts and the wizarding world. Even the ghosts at Hogwarts would feel a strange melancholy. Harry had interacted with them, and his death would be a significant event in the history of the school.
