Shauna is a heroine from Pokémon X and Pokémon Y and the main Pokémon anime.
She was voiced by Yurie Kobori in the Japanese version, and by Jo Armeniox in the English version.
Shauna made her debut appearance in Summer of Discovery!, where she first met Ash and his friends while attending Professor Sycamore's Pokémon Summer Camp. She had seen the PokéVision video that Serena filmed in Lumiose City and recognized her from it. She later used her Bulbasaur to battle Serena's Fennekin during the Pokémon Battle Tournament held that same day.
In Day Three Blockbusters!, she informed Serena about Pokémon Showcases and said her goal was to win the title of Kalos Queen, which led to Serena wanting to become a Pokémon Performer as well. She also filmed a new PokéVision video together with Tierno and Trevor as part of the activities of the Pokémon Summer Camp.
In Foggy Pokémon Orienteering!, Shauna, along with Tierno and Trevor, decided to put the PokéEnteering competition on hold to help Ash, Serena, and Clemont find Bonnie. The group later encountered a mysterious Pokémon with an X mark on their way back to the camp. Although they arrived too late at the camp to win any points in the race, they declared that helping their friends was worth it.
In Battling Into the Hall of Fame!, Shauna, Tierno, and Trevor participated in a Team Battle with Bulbasaur, Squirtle, and Charmander, respectively. Their opponents were their new friends and rivals, Ash, Serena, and Clemont using Pikachu, Fennekin, and Chespin as their partners. Shauna and her Bulbasaur were defeated after a hard battle against Pikachu and Chespin, leaving Tierno and Squirtle alone.
Shauna reappeared in Dreaming a Performer's Dream!. She had arranged a meeting with Serena and her friends in Lagoon Town. She told them that Aria would give an exhibition performance at a Pokémon Showcase there. As such, she was in the crowd at the Showcase theater together with the group, having her Bulbasaur watch it too. After watching Aria's performance, Shauna announced to Serena that she had registered for an upcoming Pokémon Showcase. She then left to train and promised to stay in contact with Serena.
She reappeared in A Showcase Debut!, where she participated in the Rookie Class Pokémon Showcase that was being held in Coumarine City. In the first round, which consisted of dressing up Pokémon with accessories, she competed against Jessie and Alouette using her Bulbasaur, which she decorated with flowers. She earned the most votes from the audience and advanced to the second round, where she performed together with her Bulbasaur and Flabébé. After the round was over, Shauna was declared the winner of the tournament, earning her first Princess Key.
She appeared in a PokéVision in Battling with Elegance and a Big Smile!, recapping her victory in the Coumarine Showcase. She reappeared in Performing with Fiery Charm!, where she watched Serena compete in the Dendemille Showcase along with Tierno and Trevor. After Serena's victory, she was seen celebrating. She also appeared in a flashback in A Legendary Photo Op!.
Shauna's next appearance was in Tag Team Battle Inspiration!, where she met up with Ash and his friends again. Together with Serena, she faced off against Ash and Tierno in a Tag Battle, which was called off.
In A Performance Pop Quiz!, she participated in the Anistar City Rookie Class Pokémon Showcase along with Serena, Jessie, and Nini. During the Theme Performance, she managed to answer Pierre's questions correctly, granting her a spot in the second round. There, she delivered a performance along with her Ivysaur and Flabébé which was well received by the audience. However, she did not get enough votes to win the competition, and ended up in second place. She later revealed she had already obtained her second Princess Key.
In Master Class Choices!, Shauna was called during a video chat by Serena, who told her about her victory following the Fleurrh City Showcase. As a result, Serena now qualifies for the Master Class Showcase.
In The Master Class Is In Session!, Shauna, Miette, Nini, Serena and Jessilee entered the Pokemon Showcase Master Class located in Gloire City. With the help of her Ivysaur, she made it to the semi-finals competing against Jessilee and Serena in order to get a spot in the finals. Unfortunately in Performing A Pathway to the Future!, Serena made it to the final round, where she would compete against Aria for the status of Kalos Queen.
