Ash would feel a deep sense of betrayal that could shatter his usually upbeat attitude. He might go through a period of self - doubt. However, his love for his Pokémon and his sense of justice would pull him out of it. Mewtwo, having already experienced betrayal from humans in the past, would be filled with a cold fury. It would use its psychic abilities to gather information about the betrayers. Ash and Mewtwo would work together, Ash learning from Mewtwo's insights and Mewtwo being inspired by Ash's tenacity in the face of betrayal.
One common theme is the exploration of trust. When Ash and Mewtwo's relationship is broken by the idea of betrayal, it makes the reader think about how fragile trust can be. Another theme could be redemption. If Mewtwo has been made to betray Ash against its will, the story might focus on how it tries to make amends.
Perhaps in the fanfic, a new and mysterious Pokémon arrives. This Pokémon is able to manipulate the thoughts of those around it. It makes Mewtwo believe that Ash is a threat to all Pokémon. So Mewtwo starts to act against Ash. Ash, on the other hand, is clueless as to why Mewtwo has suddenly turned on him. He has to dig deep into the secrets of this new Pokémon and find a way to reverse what it has done to Mewtwo.
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 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.
Ash's character can be developed through his interactions with the transformed Mewtwo. He might have to learn new ways to battle or strategize, which could make him a more well - rounded trainer. Mewtwo, on the other hand, could develop by exploring its new form. It might discover new emotions or abilities that it didn't have before. This could lead to internal conflicts, like whether to embrace this new self or try to return to its original form. Ash could be the one to help Mewtwo make that decision, further deepening their bond.
However, as time goes by, Ash could come to understand that Mewtwo's overprotectiveness comes from a place of care. He might start to rely on Mewtwo in certain situations, like when they are in an extremely dangerous and unfamiliar territory. Ash could also try to communicate with Mewtwo, asking it to let him handle some things on his own while still appreciating its protection.
In a Pokemon fanfiction with Ash and Mewtwo, it could start with Ash encountering Mewtwo in an unexpected place. Maybe in a hidden forest where Mewtwo is observing the wild Pokemon. Ash, being his curious self, tries to approach Mewtwo. Mewtwo, initially hostile, realizes Ash's pure intentions and they start an unlikely friendship. This could lead to many adventures where Ash and Mewtwo face various challenges together, like battling against a new, powerful and evil Pokemon organization.
In Ash and Mewtwo romance fanfiction, it often explores a very unique relationship. It's a stretch from their original interactions in the Pokémon series. Usually, it involves creating a deep emotional bond between Ash, the determined trainer, and Mewtwo, the powerful psychic Pokémon. This might include scenarios where they understand each other on a level not seen in the canon, perhaps Ash being the one to truly reach Mewtwo's heart and break through its often aloof exterior.
Ash and Mewtwo yaoi fanfiction can be quite interesting as it delves into the personalities of these two iconic characters from the Pokémon franchise. It might play with the idea of Mewtwo's aloofness and Ash's enthusiasm. Writers may create scenarios where they have to rely on each other more than in the original series, leading to a deepening of their relationship that goes beyond the typical trainer - Pokémon relationship.
