He could die in a battle against a very powerful and evil Pokemon. Maybe a new, extremely strong legendary Pokemon that he underestimated, and it managed to land a fatal blow.
Another way could be through some sort of illness or poison that he gets exposed to while exploring a new and dangerous area in the Pokemon XYZ world. Since he's always out there exploring, he might come across a deadly plant or a poisoned environment that his body can't fight off.
Perhaps he sacrifices himself to save his friends or Pikachu. For instance, if there was a dangerous situation like a collapsing cave or a powerful attack aimed at his friends, he could put himself in harm's way and not survive.
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.
Obviously, Dark Ash is one of the main characters. He's the center of the story with his transformed state. Serena might also be a main character as she could be trying to reach out to Ash or deal with the new Dark Ash.
One possible interesting plotline could be Dark Ash's struggle with his new, darker side while still having memories of his former self. Maybe he has to face off against his old friends who don't recognize him at first.
In some fanfictions, Ash might die while protecting his Pokémon from a powerful and evil force. He could sacrifice himself to ensure their safety.
