It could be a young and inexperienced trainer who has big dreams but is still learning the ropes. Losing the battle would be a huge setback for them.
A possible plot could be that the trainer who loses the battle is so distraught that they start to question their entire journey. They might have a moment of self - reflection and decide to train harder. Maybe they also lose a special pokemon in that battle which adds to their grief.
Deku could be a main character. Since his whole journey has been centered around his quirk, losing it would be a huge deal. He would have to face the fact that all his training and growth related to his quirk was now useless, and he'd have to start from scratch in a different way.
It could be a professional Pokemon groomer. They are known all over the region for their amazing skills in giving Pokemon haircuts. They have a special bond with each Pokemon they groom, and they often get requests from famous trainers.

A half - vampire, half - human character would be really interesting. They would have the strength and some of the powers of a vampire, but also the connection to the human world of Pokemon training.

They might face discrimination from all sides, but also find unique ways to use their abilities to their advantage in Pokemon battles.
It could be a Pokemon trainer who has a special connection with a particular Pokemon. This trainer gets recruited for an experiment because their Pokemon has shown some unique abilities. The trainer then has to balance their normal training routine with the demands of the experiment, all while protecting their beloved Pokemon from any potential harm that the experiment might bring.
A less obvious choice could be Team Rocket's Jessie. She has been around Pokémon a lot, even if in not - so - ethical ways at first. But she could have a change of heart and use her knowledge of the Pokémon underworld to clean up any illegal Pokémon trading and fighting rings as president.
A Totodile might be the main character. Totodile is a bit mischievous. It could use its big jaws to grab onto opponents and its energetic nature to perform wild and unpredictable wrestling maneuvers. Plus, its evolution into a Feraligatr could be a major part of its character arc in the fanfic as it becomes an even more formidable wrestler.
Maybe an experienced trainer who has heard rumors about a haunted house and decides to investigate. This trainer would be confident in their abilities and their Pokemon's strength.

However, they soon find out that the hauntings are real and more dangerous than they thought.
It could be a young and curious Pokemon researcher. This person is fascinated by the idea of creating Genesect and devotes all their time to studying the necessary genetics. They might be a bit of an outcast in the scientific community because their ideas are so radical.
