In the fanfiction 'Lost in the Shadows', a Pokemon dies because of a misunderstanding and a series of unfortunate events. It's a rather tragic tale that makes readers feel for the characters. Additionally, 'The Last Breath' is a story that shows a Pokemon using its last ounce of strength to protect its trainer and then succumbing to its injuries.
In some fanfiction, Dawn might be involved in a time - travel related incident. She accidentally alters the timeline in a way that causes her own death to save the Pokemon world from a great evil. This would be a complex and interesting take on the 'Dawn dies' concept.
One common theme is the exploration of grief among the trainers. When a Pokemon dies, it can shatter the bond between the trainer and the Pokemon. Trainers might have to come to terms with their own mortality as well, since the Pokemon was often like a partner in their adventures.
In a more complex story, there could be a curse placed on Pikachu by an ancient Pokemon spirit. This curse gradually weakens Pikachu over time. As it gets sicker, Ash tries everything he can to find a cure. But in the end, Pikachu's body gives out. Ash is left to deal with the grief, and he embarks on a journey to find a way to break the curse and bring Pikachu back.
There's also 'Spike's Ending'. This fanfiction could focus on how the other characters in the story react to Spike's death. It might explore their grief, and how they carry on with his memory, perhaps leading to some changes in their own lives.
One possible fanfiction could be where Aang sacrifices himself to save the world from a new, powerful dark spirit. In this story, his friends are left to carry on his legacy of peace and balance.
One could be 'The End of Sonic's Run' which explores the aftermath of Sonic's death on his friends and the world. It shows how they struggle to come to terms with the loss.
In certain fanfictions, Ash might die from an incurable disease that he contracts while exploring a new and mysterious region in the Pokémon world. His Pokémon then have to deal with his loss and some might go on a journey to find a way to bring him back. For example, Pikachu could be determined to find a mythical Pokémon that has the power to revive the dead.
In fanfiction, if Ash were to die in Pokemon XYZ, it would be a huge shock to the Pokemon world. His friends like Pikachu would be devastated. Maybe Team Rocket would even feel a strange sense of loss. It could lead to a whole new storyline where his friends try to avenge his death or carry on his legacy of becoming a Pokemon Master.
I'm not sure about the specific plot of this fanfiction as there could be many different versions. But generally, it might involve Misty's friends in the Pokémon world dealing with her death, perhaps Pikachu and Ash feeling sad and reminiscing about their adventures with her.
In fanfiction, the plot could vary greatly. Maybe it involves a dangerous battle where Barry is overpowered by a powerful Pokemon or a complex conspiracy in the Pokemon world that leads to his death. It could also be related to self - sacrifice for the greater good, like saving a town or his friends from a great threat.
