Serena

Serena is a Pokémon Trainer who is just starting her journey. However, she has a history with Ash, having been childhood friends in years gone by. Years before Ash Ketchum began his journey as a Pokemon trainer, both he and Serena attended Professor Oak's Pokemon summer camp when they were little kids. During their time, Serena got lost in the middle of a forest while trying to look for her group. A wild Poliwag jumped out of the bushes and scares her, causing her to fall and hurt her knee. She was so scared that she called for her mother. But then moments later, Ash came out of the bushes while looking for Poliwag and finds her injured. He bandaged up her wound and helped her find a way back to the campsite. Serena had developed feelings for Ash after the way he helped her and had been a close childhood friend with him ever since.
