Fanfiction about Harry is dying: What are some possible plotlines?

One possible plotline could be Harry gradually losing his magic as the 'magical cancer' progresses. He might struggle to keep it a secret from his friends, especially Hermione and Ron, who would be desperate to find a cure. Another could be that he starts having strange visions or experiences related to the magical source of this 'cancer' which could lead him on a quest to find its origin in the wizarding world, even as his health deteriorates.

One possible plotline could be that Harry is suffering from a mysterious curse. Maybe he got it during a battle with a dark wizard. His friends would then be on a desperate quest to find a cure, traveling to far - off places and consulting with various magical experts.

One possible storyline could be that in a final battle against Voldemort, Harry sacrifices himself in a way that no one could reverse. For example, he might use a powerful spell that requires his life force to destroy the last of Voldemort's Horcruxes.

Maybe a character that was thought to be an ally actually turned out to be a double - agent and cast a fatal spell on Harry.

Perhaps in this alternative universe, human Loki is a political figure. He tries to bring about radical changes to a corrupt system. However, his enemies manage to frame him for a heinous crime. Unable to prove his innocence, he is sentenced to death. His death then sparks a revolution as the people realize they have been deceived.

Maybe Naruto is affected by a dark and ancient curse. This curse was placed on him by an unknown enemy. It starts to take hold gradually, making him weak and sick. He begins to have strange visions and nightmares. His body slowly deteriorates, and he loses his appetite. His friends notice his strange behavior and the physical changes, but Naruto is determined to keep fighting until they find out what's wrong with him.

Another idea is that there is a prophecy that requires Harry's early death to save the wizarding world in a different way. He discovers this prophecy and, being the selfless hero he is, willingly accepts his fate. His death then triggers a series of events that lead to a new era of peace and harmony in the wizarding community, but his friends and allies still deeply mourn his loss.

In a fanfiction with Naruto dying from cancer, the story might focus on how the ninja world reacts. His allies from different villages might come together to try and find a cure.

His death could also lead to a shift in the power dynamics among the villages, as he was a unifying figure.

It could be due to some kind of self - sacrifice he made in a previous battle. For example, he might have used a very dangerous spell that had a side - effect of slowly killing him to save his friends or the wizarding world.
