Roxie was born and raised in Virbank City, Unova. Daughter of two entertainers, Roxie was brought up in a musical background, and was bought a Music Club at a young age. She then took up Pokémon training while studying.
Similar to Marlon, Roxie decided to campaign to make her Music Club into a Gym and becoming an officially recognized Gym Leader. She was accepted and replaced the Striaton trio when they stepped down.
