What could be the plot of an 'Ash Pokemon Experiment' fanfiction?

Perhaps a powerful and mysterious trainer. This trainer is jealous of Ash's connection with his Pokemon and his ability to conduct these experiments. He wants to prove that he is the better trainer. So he tries to disrupt Ash's experiments by challenging him to battles at inconvenient times. He also spreads false rumors about Ash's experiments being dangerous to other Pokemon, which causes some local Pokemon communities to be hostile towards Ash.

It could be a story where Ash somehow gets involved with Team Plasma's experiments. Maybe they are trying to create a new type of Pokemon using some unethical methods and Ash tries to stop them.

In this fanfiction, if Ash turns into a pokemon, perhaps he becomes a Charmander. He could struggle with being in a different form. He might have to adapt to the life of a fire - type pokemon, facing challenges like being weak against water - type attacks and trying to find a way to change back while still having adventures with his friends, who now have to protect him in a different way.

Perhaps a story where a mad scientist is conducting cruel Pokemon experiments in a secret lair. His goal is to create the ultimate fighting Pokemon by using unethical methods. A young and brave Pokemon trainer gets wind of this and decides to put a stop to it. The trainer has to battle through various mutated and tortured Pokemon created by the experiment before facing the mad scientist himself.

One interesting story could be about Ash being part of a secret Pokemon evolution experiment. In this fic, scientists might be trying to force-evolve Pikachu in a way that goes against nature. Ash has to fight to protect Pikachu and the bond they share. It shows his determination to keep his Pokemon's well - being a top priority.

The plot might involve a strange scientific experiment gone wrong. Ash volunteers for an experiment that aims to enhance the bond between trainers and Pokemon. However, something goes haywire and he begins to transform into a Pokemon. In his new form, he has to participate in Pokemon battles in a very different way. He might be able to use moves in ways that normal Pokemon can't because of his human knowledge. His transformation also causes chaos in the Pokemon community as they are not used to a human - turned - Pokemon, and his friends struggle to keep his identity a secret while trying to reverse the process.

Well, the plot could involve Ash visiting a dairy farm where there are many Miltank. One particular Miltank is very shy and doesn't produce milk like the others. Ash decides to help it gain confidence. He uses his knowledge of Pokemon and training methods. He spends time with the Miltank, shows it kindness, and eventually, the Miltank overcomes its shyness and becomes one of the best milk - producing Miltank on the farm. This story could also include Ash learning about the importance of different types of Pokemon in different industries, like the dairy industry in the Pokemon world.

A possible plot could be that Ash discovers a rare male Pokemon that has unique powers. He decides to catch it and train it. Along the way, he faces other trainers who also want this Pokemon. This leads to intense battles and strategic planning on Ash's part to keep his new male Pokemon friend safe and to help it reach its full potential.

The plot could involve a threat to Alola. Ash and Lillie, now in love and getting married, have to put their wedding plans on hold to save the region. Along the way, they discover that their love gives them extra strength. They defeat the threat together and then have a grand wedding celebration, which is attended by Pokemon trainers from all over the world.

One possibility is that Ash's Ekans could be a special one with unique abilities. Maybe it has a hidden power that helps Ash in battles against stronger opponents. For example, it could have a super-effective type of attack that is not common among Ekans, like a special poison - type move that can paralyze opponents for a long time.
