Serena is one of Ash's traveling companions during his journey in the Kalos region. Her main goal is to be named Kalos Queen, the highest prestige achievable for Pokémon Performers. She is a very kind and polite girl. She is always concerned about what her friends are doing and is always supportive of them. She also has a passion for fashion and clothes as she tries to find the prettiest clothes. Her first Pokémon was a Fennekin that she received from Professor Sycamore.

She and Ash met before the events of the series when Ash aided her in her time of need. Through her journey, Serena went through a great change in her personality as she became a very strong and determined girl, shown when she reminded herself of Ash's motto "Don't give up till it's over" and when she would take hits for her Pokémon.

In the end of the _Pokemon XY & Z_ series Serena told Ash she vowed to become better, especially for him the next time they met. She then leaned towards him and she gave him a kiss.
