Not currently -- I know what her parents do/did (her mother competed in quite a few Indigo League battles when she was around my MC's age and now gives lectures about pokemon training; her father is a scientist who works for Silph Co. in Saffron City) so I could easily build up around that.

Hmm, I do now have an idea that she's wanting to live up to her mother's legacy. Perhaps in her first Gym challenge (which I'm still not sure which one it'll be: the games start with Pewter City; my MC lives in Celadon City which has a gym but is the 4th one to be challenged in the game. She starts with a grass-type pokemon, which is great against Pewter Gym's rock type, but has no advantage or disadvantage against Celadon City's grass types) she'll lose and be unsure of how to go forward from that?
