Perhaps Ash runs away after an argument with his friends. He feels like they don't understand him. He runs off to a beach town where he meets a mysterious old trainer. The old trainer tells Ash stories of his own past adventures and failures. Ash realizes that running away isn't the solution and decides to go back to his friends, with a new perspective on their relationships.
He could go to the mountains. There are so many hidden caves and areas in the mountains that he could explore. It would be a great place for him to hide and be alone with his thoughts. Plus, there might be some powerful Pokémon that live there that he could interact with.
In the fanfic about Ash running away to Mt. Silver, it's also possible that he has some personal issues with his friends or rivals. By going to Mt. Silver, he is trying to distance himself from those relationships for a while. There, he can focus solely on his own growth as a Pokémon trainer. The harsh environment of Mt. Silver would test his limits and perhaps lead to a transformation in his training methods and his overall approach to Pokémon battles.
One possible fanfiction could be about Ash feeling overwhelmed by the constant battles and expectations in the Pokemon world, so he runs away to a secluded forest. There, he discovers a rare and mysterious Pokemon that changes his perspective on his journey.
I'm not sure of a specific title, but there might be some on fanfiction.net. You can search for 'Pokemon Ash runs away' in their search bar and look through the results. Some might have Ash running away to find a more peaceful life with his Pikachu, away from the chaos of the Pokemon League.
In some fanfictions, the character's internal conflict can be a strong motivation for running away. Twilight might be struggling with her own identity or self - worth. She is a very studious and responsible pony, but she could be having doubts about whether she's truly making a difference or if she's just living up to others' expectations. Running away could be her way of trying to find herself without the pressures of her normal life in Ponyville.
The fanfiction about Ruby running away might focus on her internal conflict. Ruby is often seen as a strong leader in RWBY, but running away shows a different side. It could be that she's running from her responsibilities, feeling overwhelmed. Or perhaps she's running towards something she believes in but others don't understand. This could lead to a story of self - discovery and growth as she figures out what she really wants and how to get back on track.
One possible interpretation could be that the female character named Hiccup has some sort of internal turmoil or external pressure that makes her run away. In fanfiction, this could be a setup for an adventure or self - discovery journey. Maybe she's running away from a restrictive society or a difficult family situation.
Well, if Mal runs away in 'descendants' fanfiction, she might be seeking freedom from the expectations placed on her. Maybe she's tired of being in the middle of all the drama and power struggles in Auradon. She could go to a hidden place, perhaps an enchanted forest where she can be alone and figure out who she really is without all the royal and villainous influences.
