BioShauna is a rival of the player in the Pokémon X and Y games for the Nintendo 3DS. She along with Tierno and Trevor are childhood friends who got their starter Pokémon from Professor Sycamore on the same day and then started their journey towards their respective dreams. They occasionally come together at events like the Pokémon Summer Camp to get each other up to speed on their journey.
Her dream is to become the world's number one Pokémon Performer. Every time she enters a Pokémon Center, she checks out the newest PokéVisions. Whenever she gets a new Pokémon or obtains a cute ribbon or something, she gets the urge to make a new PokéVision video.
Shauna watched Serena's PokéVision video and she recognized her at the Pokémon Summer Camp. She kept telling Trevor there was this really cute girl in the video and showed him Serena's PokéVision numerous times. Shauna took a liking to Serena's Fennekin and seeing it in the flesh was a great experience for her.
Shauna's Flabébé is an Orange Flower form Flabébé. It performed with Shauna's Bulbasaur in the final free performance round of the Hiyoku Tripokalon Rookie Class Tournament which was a stage of originality created by a combination of performance and moves. It helped gain enough points with its performance that Shauna (XY) was able to win the tournament.
Shauna's Ivysaur is the evolved form of Shauna's Bulbasaur. It evolved sometime after the Hiyoku Tripokalon Tournament. To help Serena's Eevee overcome its shyness and to learn how to battle, Shauna's Ivysaur teamed up with it in a tag battle against Ash and Tierno. The battle was cut short though as Serena got an idea for a new performance and wanted to practice it immediately.
