Serena is a Pokemon trainer who has a crush on Ash Ketchum . She briefly met him at Professor Oak's Summer Camp in Pallet Town years ago. Serena is a traveling companion of Ash Ketchum, Clemont, and Bonnie. Serena blushes when she sees him.
Serena first met Ash several years ago when they attended the same camp in Pallet Town. Serena wondered into the woods and got lost, and accidentally hurt her leg. Ash found her and cheered her up before walking hand-in-hand with her back to the camp. Serena ended up developing a crush on Ash, although she never saw him after that and he never learned her name.
Years later, Serena became a pokemon a trainer when she saw Ash on tv and decided to meet him again.
Serena is a complex young girl. While gentle and kind with a highly caring nature towards pretty much everyone she meets, she also has a temper that she often tries and sometimes fails to hide. She enjoys more feminine hobbies, but understands that there is a time and place for everything. She originally started her journey both to avoid becoming a Rhyhorn racer like her mother and to get to travel with Ash some, but she later started learning about herself and eventually became a Performer.
Serena has known Ash since childhood, although Ash initially forgot their first meeting until she mentioned the camp they attended and he only remembered her as "the girl with the straw hat". Secretly, Serena has developed a crush on him and seems to entertain the thought of becoming his bride. She tends to blush in his presence and gets shy at the idea of getting close to him. Even the thought of holding his hand will make her embarrassed. While she can be bothered from Ash's naive antics, Serena truly likes seeing him smile and be happy. It is Ash's bravery and determination to never give up that inspires Serena to decide her own dream and work hard to achieve it, and she adopts many training and fighting traits from him. Serena also can get upset at other girls who pay romantic attention to Ash. However, she reacts with embarrassment when other girls note the closeness between Serena and Ash. All the while, Ash truly cares for Serena and is willing to do anything to help and protect her, but he is naïve when it comes to romance and treats her as a dear friend.
