Misty would be a good character to include. She was one of Ash's first friends and has her own unique personality and set of Pokemon. Her presence could add some nostalgia to the fanfiction. And then there's Dawn, who has her own experiences in contests and battles. Her skills and her relationship with Ash could be explored further in the context of the fanfiction with Trip.
Pikachu is a must - include. It's Ash's most iconic Pokemon and always adds a lot of charm and power to the story. Brock could also be great as he has a lot of knowledge about Pokemon and can offer valuable advice.
Ash is definitely one of the main characters since he's the one being saved. His Pokémon, especially Pikachu, are likely to be main characters too as they would probably be involved in the saving process.
Another possibility is Bulbasaur. It has always been a loyal and steady companion to Ash. During the trip, it could see how far they've come together and confess its gratitude for all the experiences and growth they've shared.
Brock could be a great addition. He could provide some comic relief and also be the voice of reason. For example, when Ash and Pikachu get into some crazy situations, Brock could be the one to offer practical solutions.
Maybe Dawn could be Ash's date. They have a great friendship and have journeyed together. Their knowledge of Pokemon contests and battles could be a fun part of their date during the trip. Also, Anabel from the Battle Frontier is a possibility. She's a strong trainer, and Ash has had interactions with her. A date with her during a trip to the Battle Frontier or another region could bring some new and exciting dynamics to the story.
The 'pokemon trip saves ash fanfiction' could have a plot where Ash is on a trip to explore a rare Pokémon habitat. However, he underestimates the perils there and ends up in a life - threatening situation. His loyal Pikachu might start the rescue mission. Along the trip, Pikachu could meet other Pokémon who join in the effort. They might use their unique abilities to overcome obstacles and finally reach Ash and save him. For example, a flying - type Pokémon could help them cross a large chasm, and a water - type Pokémon could find a way through a flooded area.
Trip's character often becomes more self - aware. His initial focus on being the best trainer might shift slightly as he realizes his feelings for Ash. He starts to see Ash not just as a rival but as someone important in his life.
Brock could be an interesting secondary character. His knowledge of Pokemon and his role as a sort of mentor figure could add depth to the story. He might give Ash and Trip advice on Pokemon care or training.
The OC themselves are often popular characters. Since they are original creations, they can have all sorts of unique personalities, abilities, and backstories. For example, an OC could be a shy but brilliant Pokemon trainer who gradually overcomes their insecurities with Ash's help.
