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.
One possible scenario in this fanfiction could be that Ash encounters Mewtwo in a new, uncharted region. Mewtwo, being intrigued by Ash's unwavering spirit, decides to test him. Ash passes the tests with the help of his Pikachu and other Pokemon. This leads to Mewtwo seeing Ash as a worthy trainer and allowing itself to be caught. It would be a great twist on the usual Pokemon-catching storylines.
The relationship can develop through shared experiences. For example, if they get trapped in a strange dimension together. They'll have to rely on each other to find a way out. This mutual dependence can lead to a stronger bond.
Typically, they often focus on the contrast between Ash's warm - hearted nature and Mewtwo's more complex and often aloof personality. Their relationship is usually at the center, exploring how they come to understand and care for each other.
Ash might interact with Mewtwo in a very respectful way. He could see Mewtwo as an extremely powerful and intelligent being. He would probably listen to Mewtwo's thoughts and ideas, and work together with it on various tasks or challenges in the fanfiction.
Mewtwo's character can be developed further by exploring its emotions more deeply. For example, showing its fear of being alone or its longing for a true family. Fanfiction can also focus on Mewtwo's moral struggles, like whether it should use its powers for revenge or for good.
Well, Ash is known for his adventurous and curious nature. In Mewtwo's body, that adventurous spirit might be redirected. Instead of running around exploring physically, he might use Mewtwo's psychic powers to explore the minds of other Pokemon or discover hidden places in the psychic realm. His personality would also become more complex as he'd have to deal with Mewtwo's memories and emotions. He'd still be the same Ash at heart, but there would be an added layer of depth and thoughtfulness, perhaps a bit of melancholy too as he'd understand Mewtwo's pain of being created for the wrong reasons. And his interactions with other Pokemon and humans would be different. He might seem more intimidating at first because of Mewtwo's appearance, but as soon as he started to communicate, his friendly and helpful Ash - like personality would show through.
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.
One interesting storyline could be Ash befriending Mewtwo in a more in - depth way. Maybe Mewtwo decides to travel with Ash and his team, and they face challenges together. Ash could help Mewtwo understand the true meaning of friendship and trust, which Mewtwo has always struggled with due to its creation and past experiences.
