One theory could be that Ash has some hidden Pokémon powers that he doesn't fully understand yet. Maybe his ability to bond so deeply with Pokémon is more than just a trainer's skill. Another possibility is that his journey is all part of a grand plan by the Pokémon world to test him as one of their own. It could also be that he has a special heritage that ties him to the Pokémon in a way that no one else does.
Well, perhaps Ash is secretly a Pokémon because he has shown extraordinary empathy towards them. He can often understand their feelings without much effort. This might be a sign that he is actually part of their species on a deeper level. Also, his resilience in battles and his ability to adapt quickly could be traits that are more Pokémon - like. For example, Pokémon are known for their ability to adapt to different environments and opponents, and Ash seems to have that same quality.
There could be a connection to a legendary Pokémon. Maybe in the past, there was some kind of interaction between a legendary Pokémon and Ash's family that led to him having Pokémon - like qualities. His uncanny ability to attract rare Pokémon might also be an indication. In many Pokémon stories, special things happen to those who have a connection to the Pokémon world on a fundamental level. Ash might be one of those special cases where he is unknowingly a Pokémon or has a strong Pokémon essence within him.
If Ash was secretly a Pokémon, trainers might view Pokémon in a whole new light. They would see that Pokémon could be more like them, with complex emotions and motives. Also, Ash's relationships with other Pokémon and trainers would be re - evaluated. His Pokémon friends might see him as an equal rather than just a trainer.
Some of his Pokémon might be very confused and sad. Pokémon like Pikachu, who has been with Ash for a long time, would probably miss the adventures and battles they had together. Pikachu might try to cheer Ash up and convince him to change his mind.
Well, it could mean that his story would be a wild mix of different fan - created ideas. In fanfiction, various authors might have different takes on how he was raised, so he could be more of a rebel or have some strange powers. For example, some fanfictions might have him being raised by a rare and powerful Pokémon, which would give him a very different upbringing and perspective on the Pokémon world compared to the official story.
One interesting story could be about Ash and Pikachu encountering a female Eevee and the adventures they have together. The story might focus on how Ash helps the Eevee evolve into a Sylveon through their strong bond.
Well, perhaps in a fanfiction, Ash is exploring a new region and comes across a poisonous plant. Unknowingly, he breathes in the fumes or touches it and it makes him ill, resulting in vomiting. Or maybe a Pokémon he befriends has an ability that has an unexpected side effect on Ash, like making him nauseous and causing him to vomit. There are many creative ways that authors can come up with in Pokémon Ash Vomiting fanfiction.
One great Ash and Shadow Pokémon fanfiction could be one where Ash discovers a Shadow Pokémon in a mysterious forest. The story could focus on his journey to purify it, with lots of action and his unique bond with Pokémon guiding him.
A Darkrai could be in Ash's secret team. Darkrai is known for its ability to create nightmares, which could be used to disorient opponents in battle. It's a very powerful and mysterious Pokémon that would add an element of surprise to Ash's team.
Some of his Pokémon might sense the change in Ash immediately. Pikachu, being his closest partner, could be both curious and a bit protective. It might stay closer to Ash during battles, as if it knows Ash has a new power to draw from. Other Pokémon like Charizard might be a bit more aloof at first, but as they see the benefits of Ash's aura powers in battles and in protecting them, they would come to accept and rely on it.
One reason could be that he gets tired of the constant traveling and battles. It's a very physically and mentally exhausting lifestyle. Another might be that he experiences a major loss, like losing his beloved Pokémon, which makes him lose his passion for training. Or perhaps he discovers a new interest that he finds more fulfilling than Pokémon training.
Well, in fanfiction, Ash talking to his Pokémon has many benefits. It can lead to more complex character development. For instance, Pikachu might tell Ash about its dreams and aspirations, which can in turn influence Ash's own goals. It also makes the Pokémon seem more intelligent and sentient, as they can convey their thoughts and ideas clearly. This can result in some really thought - provoking stories where the relationship between Ash and his Pokémon is explored in great detail. It can also open up new plot possibilities, like the Pokémon guiding Ash through a mysterious place by giving detailed directions through speech.
