Shauna appears in Pokémon X and Y as a friend of the player. Shauna is energetic and curious about her friends' progress in their travels. She also enjoys solving puzzles, and is a friend of Clemont and Bonnie.
After the player becomes Champion, she will trade the player the starter Pokémon which is weak in typing to the one the player originally chose in exchange for any Pokémon owned by the player.
Shauna also appears as one of the player's partners in the Battle Maison when choosing Multi Battle.
"We were just talking about you. C'mon have a seat!"
"What? No way! He's/She's a Lil'<player's name's first letter> for sure! What do you think, Trevor?"
"You want us to call you <nickname chose>?
Yes: "OK! ♪ <player's nickname> fits you perfectly! I'm sure we're gonna be great friends, so I'll call you that, too! Hey! Can we see the Pokémon now? I want to meet my new partner soon! <eighth note>"
"Would you like to give your Pokémon a nickname?"
Yes: "So you've decided on the nickname <Pokémon's nickname>. OK! My partner is Chespin/Fennekin/Froakie! Wow! We got together great! The two of us are just way-ay-ay too cute! <music note>"
Before battle
"<player's nickname>, wait!"
"You're going to be my opponent in my Pokémon-battling debut!"
Of course!: "That's right! We're going to battle! We ARE Pokémon Trainers, after all! ♪"
Nope. What is it?:
When defeated
"Battles with friends are really, really exciting!"
After being defeated
"That reminded me of our battle in Aquacorde Town! That was the first time for both of us to battle with our Pokémon!"
When Tierno and Trevor show up
"Nothing big. How about you guys?"
"Wow! Tierny asking someone to battle? What's up with that?"
"Wow! I don't think I've ever heard you worry about being weak or strong before, Trevor! ♪ You seem a lot bolder than you used to be. Is it because you went on a journey? Or maybe it's thanks to what you learned from being with your Pokémon, and with us--your friends!"
"Speaking of which... Where's Serena?"
"I'm so glad I went on a journey. I made some great friends. And thanks to my Li'l <starter Pokémon> that I met before we left, I was able to visit many places, meet a lot of nice people, and make many wonderful memories! ♪"
In Pokémon Adventures, Shauna is an aspiring Furfrou groomer. Additionally, she is childhood friends with X, Y, Tierno, and Trevor. She is first seen talking to Y after a failed attempt at getting a depressed X to come out of his house. Although she finds it hard to believe Y's efforts will produce any results, Shauna notes that she still holds on to the hope that she and her friends will be a happy group once again.
Soon after, the legendary Pokémon Xerneas and Yveltal appear and cause havoc in Vaniville Town while battling each other. Although Y manages to get everyone to safety with her Rhyhorn, Shauna's Furfrou was sent flying during the commotion and was lost. As the five group together, Shauna states that she intends on finding her missing Furfrou. The group then sets off on their adventure as friends once again.
Neko-P (Japanese: ネコPNeko-P) is Shauna's first known Pokémon. It was first seen with its Trainer in Vaniville Town watching Y's failed attempt to get X out of his house. Later, it escaped with Shauna while Xerneas and Yveltal rampaged.
Furfrou is Shauna's second known Pokémon that she uses in her studies to be a Furfrou groomer. It was first seen with its Trainer in Vaniville Town watching Y's failed attempt to get X out of his house. During the battle between Xerneas and Yveltal, Furfrou was sent flying and was separated from its Trainer.
Shauna was introduced as a Supporter card in the Pokémon Trading Card Game during the English XY Series (the Japanese XY Era). First released in the Japanese Xerneas and Yveltal Half Decks, the Shauna card later debuted in English in the XY expansion, with each print featuring an illustration based on the official Ken Sugimori artwork for the character. With the same effect as Professor Oak's Research of Expedition Base Set, Shauna allows the player to shuffle their hand into their deck and draw five new cards.
