Give the character a unique backstory. For instance, if they grew up in a region that's not known for Pokemon training but has a strong cultural influence on how they interact with Pokemon. Maybe they come from a family of fishermen and they have a different perspective on Water - type Pokemon compared to others.
A common starting point could be getting a starter Pokemon from a local Professor. For example, in many fanfictions, the protagonist goes to Professor Oak's lab in Pallet Town and chooses between Bulbasaur, Charmander, and Squirtle. This is a classic and well - known way to start the journey.
She could have a Bulbasaur. Since she might be related to Professor Oak, it would make sense for her to start with a classic Grass - type like Bulbasaur. It's cute and has great potential in battles as it evolves.
Well, in Pokemon journey fanfiction, Alexandria Oak could be an original character. Maybe she's related to Professor Oak in some way. She could be a trainer starting her own journey, facing various challenges and making new friends along the way. For example, she might encounter rare Pokemon or get involved in local Pokemon competitions in the fictional story.
Ash could face some tough challenges in this fanfiction. He might have to train in harsh conditions to become a champion. For instance, training on a snowy mountain where Pokemon are stronger due to the environment. His team would need to adapt and grow. Maybe he gets a new Pokemon that is a bit of a troublemaker at first but later becomes a key player in his battles.
Another possibility is a Torchic. Torchic is a fire - type, and it's small and cute but can grow into a very strong Combusken and then Blaziken. It would bring a lot of energy to Fem Ash's team and could be a great partner for her in the early stages of her Pokemon journey, especially when facing off against grass - type Pokemon.
I'm not sure specifically as there could be many different plots in this fanfiction. It might involve the adventures of the trainer in the Kalos region, encounters with new Pokemon, and the journey to become a Pokemon master.
One common theme is friendship. Ash's relationships with his Pokemon and other trainers are often explored deeply. For example, how he bonds with new Pokemon he catches or how he helps his friends in tough situations.
Since it's a fanfiction about Pokemon in the Alola region, it could involve the main character exploring different islands. They might take part in the island challenges, meet unique Alola Pokemon forms, and have interactions with the local characters. For example, they could team up with Hau or Lillie to battle Team Skull or discover some hidden secrets in the Alola region's beautiful landscapes.
