Another scenario could be that he sacrifices himself to save someone important. For example, if there was a young cadet in danger, he might put himself in harm's way. He could be fatally injured while trying to stop a large-scale destruction or a dangerous weapon from being used.
In some possible scenarios, he might die heroically in a battle against a powerful enemy. Maybe while defending his comrades or an important location.
One scenario might be related to a failed mission. Maybe Naruto is sent on a top - secret mission that is much more dangerous than anyone anticipated. He could be betrayed by someone he trusts during the mission, leading to his death. Or perhaps there are some unforeseen circumstances, like a strange and deadly curse that gets unleashed during the mission which he succumbs to.
An alien race with a grudge against the Republic could also be the main antagonist. They might target Rex specifically because of his strategic importance and his role in leading many successful missions against them in the past. His death at their hands would be a major blow to the Republic's morale.
Perhaps in the fanfic, the singer's death is a mystery, and fans start to investigate, uncovering secrets about the singer's life that were previously unknown. This could involve looking into the singer's relationships, unfulfilled dreams, or hidden talents.
In some scenarios, she might die heroically in a battle against a powerful Grimm. For example, she could sacrifice herself to save her friends from a horde of Nevermores.

Or she could die due to some unforeseen magical or technological accident in the RWBY universe.

Well, it could explore themes of survival. If Rex is being tortured, how does he manage to hold on? There might also be themes related to loyalty. Does he betray his comrades under torture or does he stay true? And it could also touch on the theme of the psychological impact of extreme situations. Torture can break a person's mind, and the fanfic could show how Rex copes with that on a mental level.
Well, perhaps in the fanfic, Jake's death could lead to a change in the balance of power in Ooo. Evil forces that were previously held at bay by Jake's strength start to emerge. Maybe the Ice King, instead of seeing Jake as an obstacle to his schemes regarding Princess Bubblegum, now has free rein. Finn would have to step up in a big way, but without his best friend, it would be extremely difficult. He may struggle with feelings of guilt, thinking he could have saved Jake.
Perhaps in the fanfic, there is a curse within Shell Cottage that targets Hermione specifically. It could be an ancient, dark magic that was dormant until she arrived, and it slowly takes her life despite the efforts of her friends to save her. For example, it might start with strange symptoms like sudden weakness and then gradually lead to her death.
Well, in the 'Captain America weight gain fanfic', it could be that he is mind - controlled to overeat. Imagine an enemy using some sort of mind - control device to make Steve Rogers consume large amounts of food. Or perhaps he's on a mission in a place where food is scarce, but when he finally gets access to it, he overindulges because of the long - term deprivation. This could lead to a significant weight gain. Also, it could be a story where he has to adapt to a new civilian life after a long time as Captain America and the change in routine and diet causes him to put on pounds.
One possible scenario could be that he succumbs to the hardships in the village as a child. Maybe the villagers' hatred towards him is too much to bear, and he gets into a situation where he can't defend himself.
