Galar League Challenge
The Champion of the Galar League, who eventually becomes the World Champion.
- The Ace: He becomes this for the entire world after defeating Lance in the Pokémon World Championships Finals, gaining the title of World Champion after a hard-fought battle.
- Adaptational Badass: In the games, Leon has never lost an official battle throughout his career, but he's still only the Champion of the Galar region and is never shown battling other Champions (though Raihan is noted to be on the level of some Champions). However, during his debut in the anime, Leon defeats Lance (the Champion of the Indigo League) in the final round of the Pokémon World Championships and gains the title of World Champion - being the first trainer in the series' 20-year history to do so, and making him the implicit strongest trainer in the world.
- Adaptational Intelligence: Is shown to be warier of Chairman Rose and notices suspicious intent in some of his words. When given the chance, he arranges to stay at the mines, secretly investigating Rose behind his back.
- Always Someone Better: He defeats both Lance and Ash—the Champions of the Kanto and Alola Regions, respectively—in battle.
- Big Brother Instinct: Despite only interacting with Ash and Goh a few times, he's shown a general fondness for both of them, and didn't hesitate to shield both of them from Eternatus and telling them to run to safety, even if it meant leaving him behind.
- Blow You Away: His Charizard knows Air Slash, which gets upgraded to a Max Move when Gigantamaxed.
- Childhood Friends: With Sonia as shown in JN043.
- Competition Freak: He feels that battles are no fun unless the trainers take them and the stakes seriously. Leon also asks Ash if he can put more entertainment value for his audience into his battles as well.
- Confusion Fu: Leon and Charizard switch up their movesets frequently depending on the opponent they are battling, going through as many different moves in forty-two episodes as Cynthia's Garchomp did in the entirety of Diamond and Pearl (191, plus the Best Wishes episodes they appeared in, and this is not including Max Moves). This allows them to cover not only a wide range of types but also techniques ranging from long range combat moves to close quarters combat to moves to limit their opponent's movements.
- Cool Car: Drives a van that resembles Charizard in the third version of the opening.
- Curb Stomp Cushion: On the giving end of one during his match against Ash; Ash and Pikachu's inexperience with Dynamax aside, they hold their own reasonably well, enduring and landing several attacks, but ultimately Leon wins without ever seriously being pushed to his limits. While this is rather impressive considering Leon explicitly didn't hold back, it still goes to show that even as a Champion Ash still has room for improvement if he truly wants to be the very best.
- Dishing Out Dirt: His Charizard uses Dig, a ground type move.
- Drives Like Crazy: Implied during the 3rd opening where it shows him driving through Galar with Ash, Goh, and Chloe.
- Fantastic Rank System: He's No.1 of the world's strongest 8 in the Master Class of trainers. The Championships Tournament is for those 8 only. Goh warns Ash it's no cakewalk to get into that category. The ranking system is based on an individual trainer's win-to-lose ratio. Ash can't advance if he loses too many battles. Leon swiftly shot up to this top-tier Master Class because he's never lost an official battle.
- Mythology Gag: His opening dialogue when about to start his battle against Lance is an exact match to what he says when he prepares to battle the player in-game.
- The jacket he wears in the childhood flashback is identical to the one Hop wears in the games.
- Nice Guy: Since Ash's Pikachu spontaneously Gigantamaxes without any instruction (which could be dangerous in the wrong circumstance) he gives the boy a Dynamax Band to control the power better, and tells him to keep it after their friendly match. Leon also gives an Oran Berry to restore the defeated Pikachu's health.
- No Sense of Direction: Just like his in game counterpart. Played with in the 3rd opening where it shows him constantly reading a map while Ash, Goh and Chloe and their Pokemon are enjoying the sights
- Our Dragons Are Different: In JN042, it is confirmed he has Dragapault in this continuity which uses Dragon Darts and Dragon Rush.
- The Rival: Ash decides to enter the Pokémon World Championships in order to face Leon again after losing to him during a friendly 1-On-1 battle.
- Shock and Awe: Charizard knows Thunder Punch, and gains access to its corresponding Max Move when it Gigantamaxes. This allows it to stand against Lance's Gyarados during an Aqua Tail barrage, and land a devastating blow near the end of the battle.
- Wind from Beneath My Wings: His Charizard knows Air Slash which usually is one of his most used moves.
- World's Best Warrior: Leon's the No. 1 Pokémon trainer. And he's never lost a battle since winning the Galar League at 10.
- World's Strongest Man: Since Charizard is Leon's strongest Pokémon and Leon is the best trainer in the world, Charizard has a reasonable claim to being the strongest trainer-owned Pokémon in the world. Even after being deprived of Gigantamaxing, it still manages to gain the upper hand against Eternatus and only loses the ability to fight back after it goes full One-Winged Angel.
The Hammerlocke Gym Leader and Leon's rival.
- Adaptational Badass: The 8th Gym Leader in the games of Sword and Shield. Here, he's one of the 3 that's confirmed to be Top 8 (along with Lance and Leon, the other 5 are yet to be revealed) of the Pokémon World Championships. (That said, it has been suggested in the games that he could easily become the Champion of a region other than Galar if he wanted to.)
- Adaptational Heroism: In the anime, he fights off Oleana's subordinates to protect Sonia during the darkest day in contract to his game counterpart where he simply evacuates the gym like the other gym leaders.
- The Casanova: He tends to act very flirtatious when it comes to "beautiful women" as shown with his interactions towards Sonia.
- Dishing Out Dirt: His Duruladon knows Stone Edge.
- Extra-ore-dinary: His Pokémon is Duraludon which is part steel type which knows Metal Claw, Iron Defense and Steel Beam.
- Ship Tease: With Sonia. His interactions with her tend to be quite flirtatious and after defeating Oleana's subordinates, he winks at her. On top of that, he planned to ask her on a date if it weren't for their situation. In the Japanese version, he calls her "babe" but in the English dub, he calls her "lovely lady".
The Stow-On-Side Gym Leader who serves as Ash's challenger in JN034 and later his rival in JN039.
- Adaptational Jerkass: Compared to her original game incarnation, this version of Bea debuts as an Arrogant Kung-Fu Girl. After Ash mentions his past victory over fellow Fighting-Type Gym Leader Korrina, Bea calls her soft.
- Arrogant Kung-Fu Girl: In her first appearance, she dismisses Korrina as "too soft", which triggers Ash's temper. She also doesn't even speak to Ash once she beats him or even offers him a handshake, she simply walks away without a word as he tends to his fallen Riolu.
- Bare-Fisted Monk: She is the Fighting type Gym Leader and a master of the Galar Karate.
- Blow You Away: Her Hawlucha is part Flying type, allowing her to counter other Fighting types.
- Demoted to Extra: Her in-game ace, Machamp, only appears in an image. Grapploct is her main Pokemon instead.
- Does Not Like Shoes: As typical with Fighting Type Gym Leaders.
- Hey, You!: She refers to Ash as the "Riolu's trainer" rather than his name, even after acknowledging him as her rival.
- Like Father, Like Son: Or daughter in this case. Episode 39 reveals her attitude, battling skill and martial arts technique comes from her father who was a Dojo Master in Galar.
- No-Sell: During their first battle, Ash's improvisations don't work on her at all; he sees much greater success during their second battle.
- Not So Stoic: She loosens up significantly when sweets are involved.
- Pink Is Feminine: Downplayed. She has a pink Rotom Phone but isn't particularly feminine.
- Sugar-and-Ice Personality: She is usually seen with a stern-nonsense personality, especially during training and battles. But when she's enjoying sweets wish Ash and Goh, she shows a much softer side and even shares her slice of cake with Pikachu and Riolu.
- The Rival: She shares this role with Leon towards Ash as he vows to rematch her sometime in the World Coronation. After their second battle, she fully acknowledges Ash as a rival, with the two planning to compete to see who can defeat Leon first.
- Spectacular Spinning: Her Hitmontop knows Gyro Ball.
- The Stoic: A completely focused and no-nonsense person. Ash's strategies don't even make her flinch during their first battle.
- Sweet Tooth: Her entire party seems to love sweets. It lets down her guard enough to share some cake with Pikachu and Riolu.
- Wake-Up Call Boss: Serves as this for Ash after she defeats him in a Curb-Stomp Battle.
- When She Smiles: When Ash and Goh are enjoying sweets together they are surprised to see Bea join them and have a genuine smile, followed by a much softer side to her.
- Worthy Opponent: She views Ash and his Riolu this way after their second battle ends in a draw, openly praising them for finding a way to combat her Grapploct's Octolock.
The Ballonlea Gym Leader who appeared in episode 55.
- Establishing Character Moment: The first thing she tells Ash and Goh when she sees them is that they are lacking pink, quite similar to her in-game counterpart when she greets the player character during their Gym Challenge at Ballonlea Stadium.
- Mythology Gag: The two questions that she asks Ash and Goh are the same ones asked during her gym battle. She also has the same dialogue when they get their two questions wrong.
- Pink Is Feminine: Just like her in game counterpart, pink is what she sees in others and also gives Ash, Goh, and their Pokémon pink clothing to wear, much to their dismay (save for Cinderace, who actually likes wearing its new pink outfit).
- The Reveal: At the end, she reveals the real reason she gave them the quiz is to get them to wait patiently for Chloe to return rather than blindly go searching for her.
- Wham Line: Her last question was who they think the person behind her is. Turns out the answer was Chloe. This also leads to the real reason behind her quiz for Ash and Goh.
The Chairman of the Galar Region who serves as the Arc Villain when the anime gets around to adapting the Darkest Day storyline. The arc revolves around Rose's plan to unleash Eternatus upon Galar in an attempt to resolve the region's Dynamax energy crisis.
- Adaptation Expansion: The anime reveals that his father worked in the mines, but died in an accident. This drove him towards finding alternative forms of energy, in order to keep others from going through what he did.
- Adaptational Personality Change: Whereas in the games he was a Graceful Loser who still acted cordial to the player before going on the face Eternatus, here, Rose is much more easily excitable and freaked out. Zacian and Zamazenta damaging Eternamax Eternatus rattles him so much that he even pulls off a villanous Nightmare Face.
- Adaptational Villainy: Not to the extreme, since Rose is still a sympathetic character who's doing what he's doing for the future of Galar (which is rooted in childhood trauma, no less), but the anime's interpretation makes it clear he's The Unfettered in regards to Galar's people, not caring in the slightest if people or Pokémon end up hurt if it means his goal will still be achieved. He is even willing to attack Ash directly with his Pokémon.
- Anti-Villain: Just like his game counterpart, but somewhat less Anti and more Villain in this case.
- The Cameo: He makes a slight appearance in JN027 as his debut episode.
- Demoted to Extra: The Big Bad in Pokémon Sword and Shield, in the anime though he's an Arc Villain for the Darkest Day 4-episode subplot.
- Extra-ore-dinary: Like in the games, his Pokémon team consists of Steel-types.
- Karma Houdini: Unlike in the games, he and Oleana escape and are on the loose at the end of the Darkest Day arc.
- Obviously Evil: Due to his Arc Villain status, he's suspected as being shadier than he lets on by Leon very quickly, and even Pikachu started to make faces the moment he met Ash.
- Pet the Dog: After his Pokémon are defeated by Ash, he frantically rushes to their side and asks if they are all right, showing that he cares deeply for his team.
- Well-Intentioned Extremist: He deeply loves the region of Galar, in spite of his methods. After his father died in a mining accident and vowing no one should have to suffer the loss he had, he wants people to turn away from fossil fuels and harness the might of Eternatus instead. Oblivious to the fact that, no one can control the extraterrestrial giant-creating Pokémon.
- Would Hurt a Child: He orders two of his Pokémon to attack Ash directly during their battle.
Chairman Rose's secretary who makes her first appearance in JN042 alongside him.
- Adaptational Villainy: She fully supports Rose's scheme with Eternatus and does not reconsider changing her mind once it goes on a rampage, whereas in the games she became concerned about it and Rose's well-being when things were starting to look too dire. Going so far as to allegedly give away her Garbodor to a random subordinate only implies she's less human than implied in the games.
- Death Glare: Gives a very serious one to Ash and Pikachu for declining Rose's offer. Even Chairman Rose could feel it from behind him.
- Demoted to Extra: Her Garbordor only appears in two episodes but under the ownership of her subordinate, Her only known Pokemon she uses is Milotic to battle against Goh.
- Karma Houdini: Unlike in the games, she and Rose escape and are on the loose at the end of the Darkest Day arc.
- Little "No": Her response after being defeated by Goh after their battle.
- Making a Splash: Her only known Pokemon is Milotic that knows Water Pulse and Aqua Tail.
- Not So Stoic: Normally she is The Stoic. But at times she can show emotion, like rage.
- Undying Loyalty: Just like her game counterpart, she shows shades of this.
- You Shall Not Pass!: She does this to Goh at the end of Episode 45, resulting in a battle between them.
- Zerg Rush: She sends her Subordinates to stop Sonia and Goh.
Other Galar Characters
The granddaughter and assistant of Professor Magnolia who is doing research on what was the Darkest Day.
- Adapted Out: Her in game Yamper doesn't make any appearances in the anime. This is most likely because Yamper in Journeys belongs to Professor Cerise and mainly serves as one of Chloe's Pokemon instead.
- Childhood Friends: With Leon as shown in JN043
- Cuteness Proximity: Her reaction upon first meeting Ash's Pikachu and Goh's Raboot, squeezing their ears in delight.

- Covered in Gunge: Her face, hands and coat are all covered in mud.
- Establishing Character Moment: Upon first meeting her, she's arriving late because she forgot to set her alarm clock, immediately showing how careless she can be.
- Fashionable Asymmetry: Just like her video game counterpart, she has one red and one yellow shoe.
- Human Popsicle: After she and Gasattsu are hit by Arctozolt's Icy Wind.
- Lethal Chef: Zigzagged: When they end up making Whipped Cream Curry for lunch, even she is unimpressed with the result. At the end, the group find it surprisingly delicious.
- Nightmare Face: She and Gasattsu have these when the fossil Pokemon are about to be revealed.
- Not So Different: She and Gasattsu are equally as scatterbrained despite the quarreling they go through in the episode. With Gasattsu complaining about her being careless and her complaining he's too rough with things.
- Punny Name: She is indeed quite careless.
- The Rival: Her relationship with Gasattsu appears as this.
- Sweet Tooth: She's shown to to really love chocolate
