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, though she lacks a clear goal herself. She also enjoys solving puzzles, and is a friend of Clemont and Bonnie.
After the player becomes the Champion, she will trade the player the unevolved form of her starter Pokémon in exchange for any Pokémon owned by the player.
"<player's nickname>! Check this out! You can make Trainer PR Videos here! It's called the PR Video Studio! ♪ Making my own PR Video! It's like a dream come true! They can make a quick video for you, or you can edit your own masterpiece! ♪ I'll put my heart into those 10 seconds and put them out there for the world to see!"
"That's path over there leads to a dead end! Let's split up, chase Furfrou, and corner it in there!"
"I'll keep it from getting away, so pick a point for me to stand. Somewhere like…" (points at a spot on the east side of the hedge maze) "Over there…" (points at a spot on the west side of the hedge maze) "Over there…"
"Let me know when you've decided where I should stand! If the two of us work together, we can solve this puzzle and catch Furfrou!"
"Where should I wait? Around here? Is this place OK?"
Yes: "Got it! ♪"
No: "Oh... OK. Where should I wait?
"Should I wait in a different place?"
Yes: "OK, I'll follow you!"
No: "OK! I'll wait here! ♪"
"Maybe it would be better for me to wait where I can see in several directions…"
"<player's nickname>! Know what I think?"
"This IS a puzzle! We have to corner it where the path leads to a dead end, right? Hmm. Maybe I should wait by the entrance."
"Hey, <player's nickname>? Are we close to cornering it? Maybe it would be better if I waited over there?"
"Phew! Well done! We finally caught it!"
"<player's nickname>, you're amazing! ♪ We caught it because you understand how Pokémon feel!"
"Maybe Furfrou would've been better off if we hadn't found it…"
"If I were a Pokémon, I'd hate to have a Trainer like that! But I really love fireworks, so let's make the best of it!"
"Um… You know… I've never watched fireworks alone with a boy before./I really hope we get to be great friends, <player>…"
"We haven't even seen them yet, but I know I'll never forget these fireworks! 'Cause I watched them with you, <player>."
"… Wow! That. Was. AMAZING! I never ever want to forget this, so I'll keep this memory in an album in my heart!"
"I ran after you like crazy when I spotted you up ahead! Know what? I heard the power's back on here in Lumiose City! Some really bad people were stealing electricity from the Kalos Power Plant… and then somebody came and stopped 'em! No one knows who, but they must be awesome! Who do you think it was?"
It was me!: "Whoa! NO WAY! You, <player's nickname>?!"
Who knows?: "I guess there's someone else out there as strong as you, <player's nickname>!"
"And get this! They're gonna light the tower! Let's go see it, <player's nickname>! It's Lumiose City's most famous sight!"
"This way! Straight ahead you'll run smack into Prism Tower!"
If the player tries to go to another direction
"Hey! What are you doing? Let's go see Prism Tower!"
"You're amazing, <player's nickname>! A Legendary Pokémon wanting to be your friend like that! It's unbelievable!"
"Wh-what's going on with that outfit! Is that really you, Lysandre? Oh, whatever! <player's nickname> already beat you! What are you doing here?"
"Um… Know what I think? Even if there's only a little bit of something, it's still best to share it. Even you managed to use Mega Evolution… That's because Gyarados shared its power with you, didn't it? And not just Gyarados, but your other Pokémon, too…"
Of course!: "That's right! We're going to battle! We ARE Pokémon Trainers, after all! ♪"
Nope. What is it?: "We're going to battle, silly! We ARE Pokémon Trainers, after all! ♪"
"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 Calem/Serena?"
"I'm so glad I went on a journey. I made some great friends. And thanks to my Li'l Chespin/Fennekin/Froakie that I met before we left, I was able to visit many places, meet a lot of nice people, and make many wonderful memories! ♪"
