Serena

Biography
Ash, Serena, Clemont, Bonnie and Sawyer arrived in Snowbelle City for Ash's final Gym Battle of the Kalos League. When they went in the gym, they were greeted by Wulfric, the Gym Leader. They immediately started the battle, but to Serena's disappointment, Ash lost. Sawyer then left to train for the Kalos League.

When Ash has gone missing, Serena went to look for him. She found him and wanted to know what's wrong. He told her it was none of her business. She responded by throwing snowballs at him saying he's not "the real Ash." She then ran away crying. When a blizzard struck, Nurse Joy told everyone to come inside the Pokémon Center, but Serena wanted to find Ash. When they couldn't find him, Serena, Clemont and Bonnie waited inside a cave. After the snow cleared in the morning, Serena, Clemont and Bonnie saw a silhouette in the fog which turned out to be Ash. They found out that the Kalos League will take place in Lumiose City.
