My character's a pokemon trainer who's just passed the entrance exam (in my world, you need to be 18 and pass a test to be a trainer; pokemon can be dangerous and this is their way of regulating trainers and ensuring they have the capabilities to look after the pokemon they train).

The main people she'll meet will be other trainers -- I've not got many sorted out, only the main gym leaders copied straight from the game -- and be involved in quite a lot of pokemon battles. She has aspirations of becoming a champion trainer, and she needs to defeat the gym leaders and other trainers in order to do so.
