A mewtwo fanfic could focus on its relationship with the scientists who created it. Maybe it tries to understand their motives and eventually forgives them. Another idea is a time - travel mewtwo fanfic, where it goes back in time to prevent its own creation but then realizes that it's an important part of the Pokémon universe. And a third interesting concept could be a mewtwo fanfic that's set in a post - apocalyptic Pokémon world and mewtwo has to use its powers to rebuild society.
One idea could be that a human scientist is working on a project related to Mewtwo's powers. They start to communicate on a deeper level, and Mewtwo begins to see the human as an ally rather than an enemy. The human, in turn, tries to understand Mewtwo's complex emotions.
A Mewtwo crossover with a science - fiction universe like Star Trek could be really cool. Mewtwo's psychic powers might be seen as a threat or a wonder in the Star Trek universe. There could be a plot where Mewtwo has to prove itself to the Federation and help them solve a problem using its unique abilities.
A possible plot could be that an evil organization creates a special diaper for Mewtwo which is actually a mind - control device. Mewtwo has to struggle against the control while trying to figure out how to remove the diaper. Or perhaps Mewtwo discovers a group of baby Pokemon who are being mistreated because they are always in dirty diapers. Mewtwo uses its powers to clean and care for them, and in the process, learns about the value of kindness and nurturing.
One idea could be a story where Mew and Mewtwo team up to save the Pokemon world from a new, powerful and evil artificial Pokemon created by humans. They have to overcome their differences first, as Mewtwo still has some resentment towards humans and Mew is more open - minded.
A possible plot could be that Mewtwo, in an attempt to protect Ash from a powerful and mysterious enemy, undergoes a self - imposed TF. This transformation gives Mewtwo the ability to access a hidden power within itself. Ash, on the other hand, has to figure out how to communicate with this new - formed Mewtwo and together they face the common foe. Throughout the story, their relationship evolves as they learn more about each other's capabilities.
A possible plot is that Ash, while in Mewtwo's form, is hunted by those who fear Mewtwo's power. He has to use his own knowledge of friendship and teamwork, which is so characteristic of Ash, to convince the people and Pokemon around him that he's not a threat. This could lead to some really cool battles where Ash, in Mewtwo's body, shows his unique fighting style combined with Mewtwo's strength.
One idea could be that Ash and Mewtwo form an unexpected bond. Mewtwo, being so powerful, could initially be distrustful of Ash. But Ash's pure heart and determination slowly break through Mewtwo's defenses. They might go on a journey together to stop a new evil threat that is targeting Pokemon with strong psychic powers. Another plot could involve Mewtwo using its powers to help Ash understand some of the mysteries of the Pokemon world that he has been curious about for a long time.
Another interesting plot would be her teaming up with a young trainer. The trainer might initially be afraid of her, but as they go on adventures together, they learn to trust each other. She could use her unique abilities to help the trainer in battles and in solving mysteries in the pokemon world. For example, she might be able to communicate with other pokemon in ways that normal trainers can't, which could lead to uncovering secrets about ancient pokemon or hidden locations. This would not only strengthen their bond but also show her growth as a character who is no longer just an outcast but a valuable part of a team.
One interesting storyline could be Ash befriending Mewtwo in a more in - depth way. Maybe Ash helps Mewtwo understand the true meaning of friendship among humans and Pokemon. He could show Mewtwo that not all humans are bad by introducing him to his friends like Brock and Misty, and how they all care for their Pokemon.
Well, one interesting aspect could be the exploration of Mewtwo's character in a unique way. In fanfics, Mewtwo is often given more depth and complex emotions that might not be fully explored in the original Pokemon series. However, it's important to note that if it's a 'lemon' fanfic, it might contain inappropriate or adult - themed content which goes against the family - friendly nature of the Pokemon franchise.
