- Voiced in Japanese by: Anri KatsuVoiced in English by: Todd HaberkornVoiced in Latin American Spanish by: Roberto Gutiérrez
A young Pokémon trainer with a passion for dancing that Ash meets at Sycamore's summer camp. A close friend of Shauna and Trevor.
- Acrofatic: Believe it or not, Tierno can do a triple side flip.
- Adaptational Badass: In the games, he's not much of a battler, preferring to study moves to make a dance team. In the anime, he's a skilled trainer that incorporates dance moves into his battle style. In addition, he makes it to the Kalos League with the rest of his group, and unlike Trevor, gets past the first round and holds his own against Sawyer until Sawyer uses Mega Evolution to tip the scales.
- Ascended Extra: In the anime he stands out more than Shauna and Trevor (even being more Ash's rival than the other two are), whereas in the games Shauna fills that role. This seems to be an intentional response to his unexpected popularity in Japan, ranking third in a popularity poll.
- Badass Normal: The guy managed to get quite far in a tournament filled with Mega Evolution and Bond Phenomenon trainers without having it himself
- Big Fun: Tierno's upbeat personality allows him to make friends easily, and he is noticeably more rotund than any of his friends.
- Catchphrase: "All right!"
- Cavalier Competitor: If Tierno loses, he accepts it and shakes it off, and readies himself for the next round.
- Chekhov's Skill: Subverted; Tierno tries teaching Ash his "rhythmic style" for Ash to use in his upcoming match with Korrina. By the time Ash's group arrives in Shalour City and up to the gym battle itself, Ash has yet to master the style, and ultimately opts for his own instead.
- Dance Battler: He trains his Pokémon to incorporate dance moves in their fighting styles.
- Demoted to Extra: He's set up as a major rival in the earlier parts of the series, but largely shifts out of focus when Sawyer and Alain enter the story.
- Gang of Hats: Fitting with his character, Tierno's team consists of natural dancers (Politoed, Hitmontop and Ludicolo). And the members who aren't, are pretty good on their toes as well (especially Blastoise, of all Pokémon).
- Hopeless Suitor: Has been pining for Serena ever since her Important Haircut. Sorry, Tierno, but Serena's heart currently belongs to a certain someone (no matter how dense that someone is).
- Making a Splash: His starter is Squirtle/Wartortle/Blastoise, and he has a Ludicolo and Politoed.
- The Rival: Towards Ash's group at summer camp, but especially towards Ash, as both are passionate individuals.
- ¡Three Amigos!: With Shauna and Trevor, being one of two guys.
- The Worf Effect: Initially downplayed against Sawyer; their Kalos League battle seemed like it could go either way, with Tierno at one point even having the numbers advantage. However, it's played straight once Sawyer reveals Mega Sceptile, rendering Tierno's Rain Dance + Thunder strategy useless and taking him out in one hit.

A young Pokémon trainer whose ambition is to see every Pokémon in the Pokédex. Ash meets him and his friends, Tierno and Shauna, at Sycamore's summer camp.
- Anti-Climax: In the first episode of the Kalos League, he's revealed to have obtained a Charizardite Y, and the battle between both forms of Mega Charizard is marketed as the highlight of the episode. Trevor's Charizard ends up getting one-shot along the rest of his team.
- Blood Knight: Much like Ash's own Charizard, Charmeleon is shown to be borderline uncontrollable when it wants to battle, though it's still more obedient than Ash's was at that stage.
- Camera Fiend: Trevor likes to photograph everything that interests him.
- Curb-Stomp Battle: He loses to Alain in a three-on-three in the first match of the Lumiose Conference. Alain only used Mega Charizard X, which defeated Trevor's own Mega Charizard Y, Aerodactyl, and Florges easily.
- Geek Physique: He's very scrawny, and the shortest amongst his friends.
- Invisible Subtle Difference: He likes to take photos of rare Pokémon. "Rare", in this case, meaning they look identical to others of their species but with some extremely subtle difference like thinner antennae.
- Motor Mouth: When he shows off the pictures he took to Ash and the gang, to the point that some subs had to keep up by minimizing the text to fit everything he says during that scene.
- Mythology Gag: He is revealed to own an Aerodactyl and a Florges like in the games.
- Out of Focus: More or less gets the short end of the stick out of the ¡Three Amigos!. Tierno is collecting gym badges while Shauna is competing with Serena in Pokévision. He is collecting badges on the side, but by the time Ash meets up with him, Trevor has just one while Ash has six. While he does make it to the Kalos League, he has the unfortunate luck of facing Alain as his first opponent, which ends in a very quick Curb-Stomp Battle in which Alain didn't lose a single Pokémon.
- Playing with Fire: His starter is Charmander (which later evolved into Charmeleon and eventually Charizard).
- Super Mode: His Charizard can Mega Evolve into Mega Charizard Y.
- The Rival: He initially starts out as a rival to Clemont at the summer camp, as both are the Smart Guys of their respective groups. However, he begins to focus on collecting gym badges to compete in the Lumiose Conference and ultimately ends up as a minor rival to Ash.
- ¡Three Amigos!: With Tierno and Shauna, being one of two guys.
- Transformation Trinket: His Charizard owns a Charizardite Y that's kept in a tail bracelet while Trevor has a Key Stone held in his camera.
- The Worf Effect: Gets this badly against Alain, who one-shots every one of his Pokemon with Mega Charizard X despite Trevor having his own Mega Charizard Y.
- Voiced in Japanese by: Ikue OhtaniVoiced in English by: Robby Duncan SharpeVoiced in Latin American Spanish by: Carlos Siller
A novice Pokémon trainer from Hoenn who writes down his battle experience in a note journal. Like Ash and Tierno, Sawyer is collecting badges to enter the Lumiose Conference.
- The Apprentice: While a rival of Ash, since Sawyer is also a rookie, he looks to Ash as his unofficial mentor. The opening in which he debuted even had Sawyer literally following in Ash's footsteps.
- Ascended Fanboy: By the end of the series, he's become Steven's assistant.
- Badass Crew: His team consists of three powerful Hoenn Pokémon and three powerful Kalos Pokémon: his ace Mega Sceptile, his pseudo-Legendary Salamence, his Stone Wall Slaking, his Lightning Bruiser Clawitzer, his Glass Cannon/Stone Wall Aegislash and his Long-Range Fighter Slurpuff.
- Beware My Stinger Tail: As Mega Sceptile, Leaf Storm has the added effect of firing its sharp, pointed tail at the foe.
- Catchphrase: "I'll be sure to make a note of this experience!"
- Chekhov's Gunman: He first appeared in XY064 losing to Clemont. His proper introduction is 9 episodes later.
- Cry Cute:
- For a brief moment, he tears up when he sees Ash-Greninja launching a devastating, match-ending blow on Mega Sceptile, putting Sawyer out of the league. He is grateful for the match, though.
- He does it again while he's reviewing the matches through videos, especially the one where he lost to Ash.
- Curb-Stomp Battle: In his early appearances, he doesn't win a single battle, let alone actually knock out an opponent's Pokémon. He apparently has gotten a lot more competent thanks to Ash's advice, but still gets creamed when they face off during XY105. In said episode, his Sceptile actually manages to match Greninja and even gains the upper hand using Leaf Storm, but gets beaten in one hit once Greninja transforms. Now the problem is how his other Pokémon can't size up to Ash's.
- Curb Stomp Cushion: Mega Sceptile's battle against Ash-Greninja is this. Though it eventually loses, it manages to corner Ash-Greninja with Frenzy Plant and is capable of fighting it in close range with Leaf Blade, even landing a hit with Leaf Storm despite Ash-Greninja's speed. It gets hit with an Aerial Ace combo (super-effective) and remains standing. It takes a giant Water Shuriken from Ash-Greninja to finally bring Mega Sceptile down.
- Double Knock Out: His Salamence and Slurpuff tie with Noivern and Goodra, respectively.
- Expy: He has some similarities with Wally from Omega Ruby and Alpha Sapphire as a green-haired beginner Trainer from Hoenn that looks up to the main character for inspiration, although Sawyer is not frail and sickly. They also eventually become strong enough to wield Mega Evolution near the end and become a Worthy Opponent to the main character.
- Foil: To Ash, as with most of his rivals.
- While Ash is an experienced trainer who had traveled multiple regions, Sawyer is a relatively new trainer.
- While Sawyer takes a very analytical approaching to battling, Ash is well-known for improvisation and unconventional strategies.
- To compound it, Sawyer's main Pokémon is a Sceptile, a Pokémon that Ash also owns and who was his main battler during his travels through Sawyer's home region, Hoenn.
- Glass Cannon: His Aegislash is very strong, but also very vulnerable in its Blade Forme.
- Graceful Loser: Despite frequently losing, he treats every defeat as a learning experience. He is right out proud when Ash defeats him in the semi-finals whom Sawyer admires so much.
- Green Thumb: His starter is Treecko, a Grass-Type Pokémon which he fully evolves into Sceptile and eventually into Mega Sceptile.
- Jack-of-All-Trades: His Sceptile has close-ranged and long-ranged moves, giving trouble to Close Range Combatants with its long-ranged moves and it can defend itself with close-ranged moves from said combatants. Mega Sceptile's Lightning Rod ability makes him also great against Electric-Type moves.
- Large Ham: Mega Sceptile has a much more aggressive and an even more animal-like voice than its base form, making its battles even more intense. It also adds more to its new Dragon-Type.
- Lightning Bruiser:
- Long-Range Fighter: His Slurpuff's offensive attacks are all long-ranged. His Clawitzer averts this trope, due to its powerful and fast Aqua Jet, giving it a close-range/mid-range option.
- Look What I Can Do Now!: He improves remarkably offscreen. Sawyer was introduced with just one badge and almost no skill in battles. Roughly 20 episodes later, he's caught stronger Pokémon and has collected six badges (the same amount Ash had when he met him, even) in that time. The universe just keeps giving him tools of destruction out of nowhere when he eventually manages to evolve his Sceptile and collect the items to make it Mega Evolve. He even gathers eight Gym Badges before Ash does.
- Meaningful Name: Scottie clearly references the European Scotland setting to allude the European-like setting Kalos. However, his name saw a revision as Sawyer surely because he moved from Hoenn, a not-European-like setting.
- Mythology Gag: Never seen without a notebook where he keeps jotting down notes. Writing on notebooks is how saving game progress is depicted in OmegaRuby and AlphaSapphire.
- Oh, Crap!: When Ash-Greninja's about to unleash his giant Water Shuriken, Sawyer realizes he is done for, and was panicking when he commands Sceptile to use Leaf Storm. His face tells everything.
- Our Dragons Are Different: Owns a Dragon-type, Bagon, which fully evolves into Salamence. Also, Sceptile gains the Dragon-Type after Mega Evolving.
- Playing with Fire: Two of his Pokémon know Fire-Type moves. Bagon had Fire Fang, then Incinerate once it evolved into Salamence. His Slurpuff knows Flamethrower.
- Product Placement: It becomes clear that Sawyer exists to promote Omega Ruby and Alpha Sapphire, but at the same time, he's very late in promoting it. Half of Sawyer's team consists of Pokémon from the Hoenn generation having the Hoenn grass-starter which can Mega-evolve (a Mega-evolution that was added in the Ruby and Sapphire remakes), a Slaking, as well as said region's pseudo-legendary dragon, Salamence.
- The Rival:
- To Ash as another Pokémon trainer collecting badges for the Lumiose Conference. He initially looks up to Ash and Sawyer dedicated himself to become stronger to eventually surpass his idol. As a result, Sawyer has grown so much that he becomes one of Ash's two main rivals in the Kalos League.
- After evolving into Grovyle, it has become a rival to Ash's Frogadier, and they grinned at each other whenever they met. Their relationship has continued as this even after their final evolution, although with less grinning.
- Spoiler Opening: The Opening to XY&Z revealed that Sawyer's Sceptile would gain the ability to Mega Evolve.
- Stone Wall: His Slaking is mostly focused on stalling. It takes hits like nothing and can heal itself. However, it barely moves or attacks, and it only counterattacks the opponent at the right moment.
- Sudden Name Change: Was previously called Scottie in his small debut episode, though the writers easily made the change due to never referring to Sawyer as his previous name in the episode.
- Super Mode: His Sceptile can Mega-evolve by the league.
- Sweet Tooth: Has said that he loves sweets when presented with Serena's desserts and Lumiose Galettes.
- Took a Level in Badass:
- He finally manages to defeat Ash during their third battle. While his Doublade still lost to Ash's Noivern, his newly aqcuired Clawitzer took down both Noivern and Hawlucha before losing to Greninja, and Sceptile managed to defeat Greninja largely because Ash was forcing the transformation too much instead of letting it happen naturally.
- Having made it all the way to the Kalos League semi-finals and giving Ash a very challenging full 6v6 battle that Sawyer narrowly lost, compared to how Ash did his first time around in the Indigo League, he sure has taken in several levels of it.
- Training from Hell: He mentioned that he worked very hard to catch up to Ash, and eventually the results show as he collects eight badges before Ash does and defeats Ash in a 3-on-3 match.
- Transformation Trinket: At the Lumiose Conference, his signature notebook's bookmark is equipped with a Key Stone while his Sceptile has a Sceptilite clipped onto a green scarf around its neck.
- Warts and All: Downplayed and eventually subverted. After Ash loses to Wulfric, Sawyer leaves the team, silently concerned his idol has fallen behind him. However, he's confident that Ash will bounce back in time for the Kalos League, which he does, restoring Sawyer's faith in him.
- Weak, but Skilled: All throughout the rivalry, Sawyer is shown to be far below Ash in terms of raw power, even after he Takes a Level in Badass. He makes up for this through tactics, having analyzed Ash's battling style from their previous encounters and preparing counter-strategies.
- When Trees Attack: Sceptile knows the ultimate Grass-Type attack, Frenzy Plant, a mass of gigantic roots that swamp the opponent in all directions.
- The Worf Barrage: Despite Frenzy Plant being the most powerful Grass-Type attack and earlier having defeated Tierno's Blastoise and Ash's Pikachu, Sceptile's Frenzy Plant never hits Greninja.
- Worthy Opponent: What Sawyer and his Sceptile proves to be when facing Ash and his Greninja in the semi-finals. Even after losing, he was happy for Ash and vows to get stronger and one day surpass him.

A young and outgoing Pokémon trainer who loves PokéVision videos. She becomes acquainted to Ash and co. at Sycamore's summer camp.
- Badass Adorable: Unlike her friends, who fully evolve their starters, her Bulbasaur stops evolving at Ivysaur, presumably because the massive Venusaur wouldn't be as useful in Showcases.
- Genki Girl: Every bit as excitable as her game counterpart.
- Graceful Loser: She cries a little when she's unable to go to the final round of the final showcase, but she encourages Serena to go for the gold.
- Green Thumb: Her starter is Bulbasaur/Ivysaur, a Grass-Type.
- Instant Expert: Despite being a rookie performer, she catches on to it with relative ease, even winning her first showcase.
- The Rival: To Ash's group at summer camp, but especially to Serena, who also has an interest in PokéVision.
- Shipper on Deck: Like Miette, Shauna teases Serena about her crush on Ash.
- ¡Three Amigos!: With Trevor and Tierno, with her being the girl.
- Tomboy and Girly Girl: The tomboy to Serena's girly girl.

A famous Pokémon Performer. Aria is the current Kalos Queen.
- The Ace: She is the undisputed best Pokémon Performer in all of Kalos.
- Ascended Extra: Her first few appearances were minor ones, usually through videos or flashbacks. Then, Aria's role is expanded a little more when she meets Serena while in disguise.
- Clark Kenting: Add glasses, put on a hat, and you got Ariana (Elena).
- Curtains Match the Window: Red hair with red eyes.
- Famed in Story: She is the crowned Kalos Queen that every other Pokémon Performer strives to achieve. She still gets to keep it for much longer after the Master Class Showcase is over.
- Opera Gloves: Her performance dress comes with long white gloves.
- Pimped-Out Dress: Her primary dress when seen as the Kalos Queen is odd to say the very least. Somehow combining a neck-tie with a matching thigh-high Zettai Ryouiki, white Opera Gloves, and Frills of Justice.
- Status Quo Is God: Unsurprisingly, she easily gets to keep her Kalos Queen title for even longer after getting almost double the amount of votes Serena had at the Master Class Showcase.

A Pokémon Performer knowledgeable in cooking Poké Puffs. She develops a crush on Ash, becoming a rival to Serena.
- Arc Welding: Introduced as a rival to Serena for a couple of things (baking, Ash). Later, Showcases are introduced and Serena focuses her attention on the competition, so when Miette returns, she has conveniently the same goal in mind, keeping their rivalry fresh.
- Ascended Extra: Was a One-Shot Character in an early XY episode, but makes a return about 50 episodes later.
- Betty and Veronica: The Veronica to Serena's Betty for Ash's Archie.
- Blue/Orange Contrast: She dresses in blue with bits of orange like her tie and hair ribbon.
- Chekhov's Gun: When Serena runs afoul of some wild Swirlix, it was Miette who realized that they were disturbed by something. She immediately points out that the reason she knows their behavior is because her signature Pokémon, Slurpuff, is Swirlix's evolved form.
- Cooking Duel: Serena and her enter a Poké Puff Contest in order to find out who makes better Poké Puffs.
- The Gadfly: Plays this role to Serena with glee. She's fond of popping up behind her out of nowhere to startle her, and using her crush on Ash against her by implying that she'll steal him away from her. It's pretty clear that her actual interest in Ash, if any, is nowhere near as genuine as Serena's, she just likes seeing her flustered.
- Graceful Loser: She nearly breaks in tears for not making it to the semifinals, but she's able to compose herself and cheer on Serena's progress.
- It Amused Me: Possibly one of the reasons why she teases Serena on her feelings on Ash, just to see her get comically flustered over them.
- Meaningful Name: Millefeui is a reference to the mille-feuille dessert, fitting with her being good at baking. Her dub name (Miette) is French for "Breadcrumb".
- No Sense of Personal Space: She seems to enjoy sneaking up behind Serena and getting startling close to her when making sly remarks about Ash, particularly at the end of the Dendemille Showcase. She also clings onto Ash's arm during the dance episode after he accepts to be her partner, much to Serena's annoyance. Ash is uncomfortable a bit with the closeness, but is too kind to not tell her to get off.
- Right for the Wrong Reasons: Upon seeing Serena's new look, Miette was correct that Serena changed her appearances for a reason but had the facts wrong as she thought she did so for Ash, although she was teasing her a little bit.
- The Rival: Towards Serena as a fellow Pokémon Performer. Miette did well enough to score third place in the Dendemille Showcase she competed in against Serena. She also pretends to be a romantic rival as well, to Serena's chagrin.
- Running Gag: Practically every time she makes an appearance in an episode, her first order of business is to tease Serena on her feelings while putting the moves on Ash right in front of her.
- Shipper on Deck: Immediately catches on to Serena's crush on Ash, and teases her about it just to get on her nerves. It's implied (and ultimately confirmed when the group splits up after the Master Class Showcase) that she's doing it at least partially to push Serena to act on her feelings.
- Supreme Chef: A Poké Puff cook.
- The Tease: Miette whispers to Serena that she might take Ash for herself if she doesn't make her move; causing her to blush.
- True Blue Femininity: She dresses up in blue to contrast Serena's red and pinks.
- Trying Not to Cry: Before congratulating Serena on her win of the first round of the Master Class Showcase, she cries due to having lost to her at that round. Even after wiping her tears, the poor girl still breaks down a bit in front of Serena.
- Who Wears Short Shorts?
- Voiced in Japanese by: Motoko KumaiVoiced in English by: Jenny EmmVoiced in Latin American Spanish by: Georgina "Gina" Sánchez
A rookie Pokémon Performer who trains her Pokémon to follow a dance routine she calls "Heartbreak."
- Abhorrent Admirer: Her Smoochum is attracted to Serena's Pancham, who wants nothing to do with her.
- Big Fun: She's pretty chubby, and has a cheerful disposition.
- Girlish Pigtails: Her hairstyle, which comes with two tiny red hair-ties.
- Graceful Loser: She takes her early loss in the Anistar Showcase well, and wishes Serena luck for the performance portion.
- Nice Hat: Wears a tiny red hat with a pink ribbon band.
- The Rival: Towards Serena as a fellow Pokémon Performer. The two meet each other in XY050, and decide to show off their performances to one another for critique. In episode XY091, they compete against one another in the Anistar Showcase.
- Shipper on Deck: She (like the rest of Serena's rivals) is very much aware of Serena's feelings for Ash and joins in teasing her about it when she meets her in the Master Class.
- Small Name, Big Ego: In the dub, once she appears in Serena's second performance, she nearly borders on being the Jerkass rival to Serena if it hadn't been for her being a Graceful Loser and Serena (and Shauna) being too nice to her egotistical boasts.
- Trying Not to Cry: While still out on stage for the results, she holds her head down, though unable to hold back tears, after losing to Jessie at first round of the Master Class Showcase.
