A plotline might involve Ash as a female Mewtwo being hunted by some evil organization that wants to capture and study her. She then has to use her new form and wits to evade them. It could also include her trying to find a way to turn back into her original self while also learning about the secrets of the Mewtwo species.
In some fanfics, the plot could be that Ash as a female Mewtwo forms a new bond with other Pokémon who are outcasts. Together, they try to change the way Pokémon are treated in the world. Or perhaps she discovers a hidden ability in her Mewtwo form that could potentially save the Pokémon world from a great danger.
One possible plotline could be that Ash is betrayed by his so - called friends in the Pokémon world. They might spread false rumors about him, making everyone turn against him. Meanwhile, Mewtwo, who has formed an unlikely bond with Ash, is also betrayed by the scientists who created it again. They try to recapture Mewtwo to use it for their evil experiments. Ash and Mewtwo then team up to fight against their betrayers and prove their worth.
One possible plotline is a redemption story for Mewtwo. He starts off as a bit of an outcast or a threat, but through his interactions with Mew, he begins to see the value in life and friendship. Another could be a search for power. They both realize they can gain more strength by working together and embark on a journey to unlock hidden powers within themselves.
One possible motive could be that Mewtwo sees Ash as a threat to its own power or freedom. Ash is constantly on a journey to catch and train Pokémon, and Mewtwo, being a powerful and intelligent Pokémon, might view Ash's actions as a potential danger to its kind or its own existence.
It could be that Mewtwo is on a quest to find its true origin or purpose. Ash joins Mewtwo on this journey. Along the way, they meet other powerful Pokémon and trainers. There are battles and competitions, but also moments of self - discovery for both Ash and Mewtwo. The fanfic might explore themes of identity, friendship, and the power of Pokémon in a more profound way through this plot.
In an 'Ash into Mewtwo' fanfic, one aspect could be the change in relationships. His Pokémon might not recognize him at first, and he'd have to find a way to communicate and regain their trust. Also, trainers like Misty and Brock would be shocked. The fanfic could delve into how Ash tries to convince them that he's still the same person inside, just in a different form.
One possible plotline could be Ash and Froakie's journey to become stronger together. They might face various challenges in Pokémon battles and overcome them with their bond. Another could be Froakie having some special ability that Ash helps it to discover and master.
The relationship could start with mutual respect. Ash respects Mewtwo's power and intelligence, and Mewtwo respects Ash's courage. Then, through shared experiences like helping other Pokémon in need, they start to trust each other more. This trust can then turn into a deeper emotional connection.
Well, one way is through shared dreams. Mewtwo could enter Ash's dreams and they could communicate on a deeper level there. This would be a very unique way to develop their relationship as it's not a typical form of interaction. Ash could learn more about Mewtwo's fears and hopes in these dream encounters.
One possible plotline could be that Ash starts from humble beginnings. Maybe he is an underdog in a competition related to Kohl's, like a Kohl's - sponsored sports event. He faces tough opponents but through his determination and unique skills, he gradually climbs the ranks and eventually becomes the champion.
A plotline could also be that Ash's transformation into Kolos Chompaine is part of a prophecy or a greater plan. There could be a group of characters who are either helping him fulfill this prophecy or trying to stop it. Along the way, Ash might discover hidden powers within the Kolos Chompaine form. He could also form new relationships with other characters who are either intrigued or afraid of his new form, and these relationships could shape the overall story as he tries to figure out his purpose in this new state.
