Serena (セレナ) is a Pokemon Trainer in the Pokémon X and Y games. In the Pokémon anime series, she is an aspiring Pokémon Performer and a former traveling companion to Ash Ketchum.
During the first episode, she was very sassy and rebellious towards her own mother, and formerly hated Rhyhorn racing. However she later proves herself to be very kind and polite, being able to get along with others pretty well, and has shown concern for others (her friends).
She loves fashion and is particular about her appearance (she even adopted the habit of picking the outfit her mother won't choose). Serena is skilled in baking, making her cookies/poke-puffs for both her friends and the other Pokemon. She hates to be wet or muddy.
One thing that shines about her character is her deep affection towards Ash, ever since he saved her from a wild Poliwag and guided her back to the camp site. Although Serena hadn't seen Ash in years, she still recognizes him (after watching him on television), and embarked on a journey to find him (returning the handkerchief). Serena admires his sense of determination and takes his advice to heart, and often encourages him in his battles. She also blushes when looking at or talking to him. At the end of their journey before leaving for Hoenn, Serena ultimately musters up the courage to kiss Ash Ketchum.
At first she was uncertain of her goal, but in Dreaming a Performer's Dream, she decided to become a top-class Pokemon Performer (with the title of Kalos Queen), and hoping to one day face-off against Aria (the current Kalos Queen).
According to the anime, she appears to have known Ash Ketchum before and have been childhood friends with him ever since. Serena met Ash at the time they attended Professor Oak's Pokémon summer camp in Pallet Town. During that time, she got lost in the middle of a forest while trying to find her group. Just then, a wild Poliwag jumped out of the bushes and scared her, causing her to fall on the ground and hurt her knee. Scared and upset, she called out for her mother for help. But moments later, Ash came out of the bushes calling for Poliwag. He was also wondering through the forest looking for the same Poliwag. While he was looking for it, he stumbled upon the young and frightened girl. Seeing how incredibly hurt she is, he bandages her knee up with his clean, blue handkerchief. Then he lent her his hand, warning her to not give up til it's over, and helped her stand up on her feet. After that, he escorted her back to the campsite. Ever since their first encounter, Serena developed romantic feelings for him, and she kept the handkerchief as a reminder of the day she first met Ash.

She carries around a pink bag with black decals on it. She has a Mega Ring on her left wrist.

Anime (XY060-XYZ Series)
Serena's second, current and main outfit in the anime consists of a light pink dress over a grayish-black tank-top with a white collar. The dress is tied at the collar with a blue ribbon that Ash gave her in "Under the Pledging Tree!". Over her dress, she wears a long red vest with large pockets. She also wears black stockings and brown boots. On her head, she wears a pink-red fedora with a black hatband.
- In Giving Chase at the Rhyhorn Race!, during her flashbacks that shows her childhood with Ash, Serena wore a straw hat with a pink bow tied around it and a pink dress with pink shoes.
- In "Battling at Full Volume!", Serena posed as Ash by wearing his clothing.
- Rhyhorn (Diancie and the Cocoon of Destruction and "A Race for Home!")
- Skiddo ("A Race for Home!")
- Goomy ("One for the Goomy!")
- Frogadier ("So You're Having a Bad Day!")
- Chespin ("So You're Having a Bad Day!")
- Mamoswine ("Over the Mountain of Snow!")
- Pikachu ("Battling at Full Volume!")
- Talonflame (Volcanion and the Mechanical Marvel)
- She is the only female traveling companion to have a canonical crush on Ash, and also the first female companion to kiss Ash. Interestingly, she is the first one to know him before the start of the series. Whenever it has been openly discussed with her by another character, rather than attempting to deny it, Serena instead blushes and acts embarrassed.
- She is also the only female traveling companion who never got into an argument with Ash on a regular basis or be easily irritated by his actions, as Misty, May, Dawn (on a smaller extent) and Iris have all been easily irritated by his recklessness and have argued with him during their travels with him. The only time both Ash and Serena ever argued was in "Seeing the Forest for the Trees!", but it was over something serious instead of childish.
- Unlike Ash's other female-traveling companions, she was personally invited by him to join. She was also the only one to not get shocked by his Pikachu (nor does she own a bike).
- Serena physical change later in the series reflects the Japanese tradition involving women cutting their hair short to signify their new-found resolve.
- Serena's Pancham is the only Pokemon she has that is a male. Also, her Sylveon is the very first Pokemon owned by the main character to be a pure Fairy-Type (not counting Clemont's Dedenne which is a dual Fairy/Electric-type).
- Serena shares a lot of characteristics with May from the Advanced Generation series:
- Neither knew what their goal was at first, but eventually focused on one related to beauty and style.
- Both chose the Fire-Type starter: Torchic in May's case and Fennekin in Serena's.
- Both have caught a Pokémon based on a bear: Munchlax and Pancham, respectively.
- Both have obtained an Eevee that has evolved. (A Glaceon and Sylveon, respectively).
- Both were expected to have the same career as one of their parents, (a Gym Leader and Rhyhorn Racer respectively), neither of which wanted to pursue.
- Both girls pay attention to fashion, albeit in different areas: May focuses more on swimsuits while Serena focuses on outerwear.
- Serena also shares some characteristics with Dawn from the Diamond and Pearl series:
- Their starter Pokémon defended them from wild Bug-type Pokémon (Fennekin defended Serena from a Vespiquen and Piplup defended Dawn from an Ariados).
- They both become renowned through media (PokéVision and Showcases for Serena and The Wallace Cup for Dawn).
- They both had a large number of rivals in their professions for the the top spot.
- Since the beginning (especially when they first meet), they both had great admiration for Ash and his actions out of love for Pokémon (when Ash helped an agitated Garchomp on Prism Tower on live TV for Serena and when he rescued Pikachu by climbing one of Team Rocket's mechas for Dawn), and are never judgmental of and very kind to him, even going as far as always believing in Ash to win his battles.
- Serena is similar to Hinata Hyuga from the Naruto series in how they both have feelings for the main protagonist and were inspired by their resolve (a personality trait that both girls adopted).
- Serena is also similar to Isabella from Phineas and Ferb:
- They both have a crush on the male protagonist. (Serena on Ash & Isabella on Phineas)
- Neither of their crushes are aware that they have feelings for them.
- They both kissed the male protagonist.
