Serena

Serena is a main character of the series, and a new Pokemon trainer

History
As a young child, Serena was sent to  Kanto,  against her will, to attend a Pokémon Summer  Camp,  which was hosted by  Professor Oak. One day, while at the camp, she got lost in a nearby forest and was startled by a Poliwag, falling over and hurting her knee. Then, she met  Ash Ketchum, who was looking for the same Poliwag and spotted Serena. Noticing her knee injury, he pulled out a handkerchief and wrapped it around her wounded knee, saying that it is a good-luck charm and that the pain would go away. However, when Serena's knee continued to hurt, Ash advised her to never give up until the end and helped her up before escorting her out of the forest. Afterwards, she returned to Kalos, bringing along the handkerchief and the memory of her meeting with Ash. Serena made her first onscreen appearance in Kalos, Where Dreams and Adventures Begin!, where she was forcibly woken up by her mother's Fletchling. In Lumiose City Pursuit!, she attempted to practice Rhyhorn racing after being encouraged by her mother, a famous Rhyhorn racer herself. However, Serena's attempts at controlling her mother's Rhyhorn ended with her being sent crashing into the ground.

Later that evening, Serena complained about her earlier practice leaving several scratches on her face. She sat down to watch a news report on an incident that was occurring in Lumiose City. On the screen, she saw Ash trying to calm down a rampaging Garchomp at Prism Tower and recognized Ash as a boy she had known in her childhood. The next day, while feeding Rhyhorn, Serena thought aloud that something interesting was going to happen and that it involved Ash.

She began her Pokémon journey in A Battle of Aerial Mobility! when she set off to Professor Sycamore's lab in Lumiose City. Immediately upon arriving, Serena questioned the Professor about the boy on television and he confirmed that it was indeed Ash Ketchum. However, to Serena's disappointment, Ash had already left Lumiose City the previous day. Serena was then offered to choose her starter Pokémon.
