There was not much similarity between Pokemon Leafgreen and the previous versions because the Pokemon series had been modified and adapted many times. There might be some differences between the different versions.
However, there were some differences in the plot between Pokemon Leafgreen and the previous versions. In Leafy's version, Billy and his friends found a mysterious Pokemon ball and decided to go to the Pokémon Center to find the whereabouts of the ball. In this version, Billy's character became more independent and confident, and his journey became more challenging and dramatic.
In addition, Ye Lu also introduced some new storylines and characters, such as Xiao Yao and Pikachu, who met on the road and became good friends. Leafy's version also added some new Pokémon, including new evolutionary forms and special abilities to make the game more interesting and diverse.
The plot of Pokemon Leafgreen was different from the previous versions, but they were both excellent games that attracted countless players.
Ash could be one. He has a way of befriending all kinds of Pokémon, and his encounter with a friendly Mewtwo would be an exciting story. He could learn a lot from Mewtwo's psychic powers and wisdom.
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.
Perhaps in a dangerous environment like an unstable cave or a place filled with wild and aggressive Pokémon. Mewtwo would constantly be on guard around Ash, using its powers to sense any approaching threats and keeping Ash away from potential danger areas. It might even carry Ash to safety if it senses immediate danger.
The Mewtwo real story is that it was created in a laboratory. Scientists used Mew's DNA to create Mewtwo. Mewtwo was genetically engineered to be a powerful Pokémon. It was created with the intention of being a weapon. However, Mewtwo soon realized its own existence and purpose and rebelled against its creators.
There might be some fanfiction out there that deals with the concept in a non - inappropriate way. However, it's not a very common or mainstream theme. You could try searching on some fan - made fiction websites, but be prepared to sift through a lot of content to find something suitable.
There could be other Pokémon like Pikachu. Pikachu could be their friend who helps the little brother adjust to the new world. He could also offer some comic relief in the story. Another possible character could be Ash. Ash has a lot of experience with Pokémon, and he could offer some guidance to Mewtwo on how to take care of his little brother.
The relationship could be developed through shared dreams. Maybe Mewtwo has the ability to enter Ash's dreams, and in these dreams, they have adventures together that are different from their real - world experiences. This would create a very special and unique bond between them.
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.
