Hoenn Gym Leaders
- Voiced in Japanese by: Yuri ShiratoriVoiced in English by: Karen NeillVoiced in Latin American Spanish by: Liliana Barba
The rock-type specialist that presides over the Rustboro Gym.
- Badass Teacher: Being both a Gym Leader and a Beginner class teacher really has its merits.
- Secret Weapon: Nosepass comes across this way - Ash had no idea what to expect of it, and its unique range of moves forced him and Pikachu to think outside the box to win.
- Warm-Up Boss: The first Hoenn Gym Leader Ash faced (in an official capacity, that is), but no pushover - her Geodude defeated Treecko despite a good effort from Ash, who needed to show how in sync he and Pikachu really can be, especially with the effective strategies she and her Nosepass implemented. Of course, Ash's victory here (fairly soon after an impressive Silver Conference showing) put him on an overconfident high which Brawley was there to straighten out soon after
- Voiced in Japanese by: Kohei KiyasuVoiced in English by: Jason GriffithVoiced in Latin American Spanish by: Noé Velásquez
Fighting-type gym leader of Dewford Town.
- Curbstomp Battle: After Makuhita evolved into Hariyama, it finished Treecko in a single strike.
- Eyes Always Shut: Makuhita.
- Humble Pie: Ash thought Brawley didn't take training seriously at all until the relaxed Gym Leader handed his ass to him. The lesson of training by "playing/working with nature" affected Ash for the rest of AG, too.
- Nice Guy: Cheery, patient, and easygoing. His good-natured attitude in his first appearance practically sets you against Ash - who was on overconfident high after his Silver Conference performance and earning his first Hoenn Badge against Roxanne.
- Subordinate Excuse: One of his apprentices has feelings for him.
- Surfer Dude: In the dub.
- Took a Level in Badass: He was already pummeling Ash's Treecko when his Makuhita evolved. Ash was well aware that Brawley would only be stronger when they had their rematch (having gotten right to work at training his new Hariyama), and he wasn't mistaken about this.
- Wake-Up Call Boss: As in the games, this is invoked - Ash loses to him due to overconfidence and it becomes a learning curve for him as a trainer.
- Voiced in Japanese by: Kenichi OgataVoiced in English by: Dan GreenVoiced in Latin American Spanish by: Armando Réndiz (episode 40), Jorge Santos (episode 59)
Setting up shop in Mauville City, Wattson's energetic attitude fits in with his type of choice.
- Curb-Stomp Battle: He unintentionally gets beaten by a fever stricken Pikachu.
- The Dog Bites Back: He got his "revenge" for Ash's sound victory when he set his new Manectric (freshly-evolved from his recently-caught Electrike) against Torkoal in a friendly match, and basically dictated the course of the battle from Point A. Also literally, as Manectric is a dog.
- Heroic BSoD: After being defeated by Ash so easily Wattson started to place doubt in himself as a Gym Leader. Befriending an Electrike snaps him out of it.
- Hoist by His Own Petard: The mechanical Raikou that gave Pikachu his electric fever was created by Wattson, thus, it was partly his own fault he was easily trounced in the gym battle.
- The Hyena: Even when he's down, he still finds some way to get a chortle in.
- Voiced in Japanese by: Rio NatsukiVoiced in English by: Lisa OrtizVoiced in Latin American Spanish by: María Fernanda Morales
Runs the Lavaridge Town hotsprings, which also doubles as her fire-type gym. She's a novice Gym Leader, having just taken the job from her retiring grandfather.
- Bare Your Midriff: Her outfit.
- Curtains Match the Window: She's as hyper and naive as her Fire-Type nature.
- Death-or-Glory Attack: Was really fond of using Overheat in her match. This comes back to bite her, as Overheat reduces in power whenever it's used, resulting in a flashy pillar of fire, but doing no damage to Ash's sleeping Corpfish.
- The Ditz: She knows very little about being a Gym Leader being that she's new to the position. Ash came to the Gym originally planning to take on her grandfather, who'd just retired and given Flannery his job.
- Heiress To The Dojo: She inherited the Gym from her grandfather after his retirement.
- Naïve Newcomer: Ash is Flannery's first opponent as the new Gym Leader. She makes some rookie mistakes during their match, most notably relying too much on Overheat. Her grandfather criticizes her for this, but he also commends her for being able to learn quickly and keep up with Ash.
- Voiced in Japanese by: Jurota KosugiVoiced in English by: Dan GreenVoiced in Latin American Spanish by: Enrique Mederos (episode 3), Salvador Delgado (episodes 69-70)
- Graceful Loser: As expected of a Gym Leader. It's Max who has a difficult time processing that Norman can lose.
- Happily Married: With Caroline.
- Lightning Bruiser: In his first appearance, Vigoroth is fast and strong enough to beat Pikachu. That Pikachu ties with it in a rematch is considered an accomplishment (particularly since it beat Torkoal in a single move).
- Mighty Glacier: His Slaking was literally no slouch either in their battle giving Groyle a hell of a match.
- Papa Wolf: Team Rocket found this out the hard way, having (accidentally) stolen his daughter's Torchic.
- What Could Have Been: In-universe - if Ash had at least three Pokémon when he first met Norman, he'd have been the first Gym Leader Ash fought, which they both acknowledge. Norman still praised Ash for the maturity of wanting to start over, though, and was impressed by his growth when they met again later on.
- Voiced in Japanese by: Hyo-seiVoiced in English by: Amy BirnbaumVoiced in Latin American Spanish by: Erica Edwards
Flying-type specialist based in Fortree City.
- Demoted to Extra: She only uses her Skarmory (a staple of her team in all versions of the Hoenn games) as a mount, and doesn't actually use it to battle Ash in their gym match.
- Extra Oredinary: Skarmory, which she doesn't use in her battle.
- Giant Flyer: Her Skarmory is much larger than any normal Skarmory, enough to carry Winona and another passenger on its back.
- Voiced in English by: Jason Griffith (Tate), Andi Whaley (Liza)
Twin psychics, and leader of the Mossdeep Gym.
- Birds of a Feather: Liza and Tate, with May and Max, respectively. The boys especially, having common ground in seeing their sister as annoying.
- BrotherSister Team: Once they get their act together, they make a devastating tag team.
- Dishing Out Dirt: Solrock and Lunatone's secondary type.
- Dual Boss: Ash has to fight them both in a double battle. They have one Pokémon apiece, and Ash had to send in two of his own.
- Sibling Seniority Squabble: Apparently, Liza's the older twin, and she doesn't stop rubbing in this fact in Tate's face whenever they spar for practice.
- Voiced in Japanese by: Show HayamiVoiced in English by: Sean SchemmelVoiced in Latin American Spanish by: César Arias
- And Now For Something Completely Different: His gym battle is very different compared to previous Gym Leaders. It comes in 2 parts and it is a 5 on 5 battle. The first half is a double battle and then after both of Juan's Pokémon are defeated, they move to a different stage and do a single battle for the remainder.
- Badass Moustache: The strongest Gym Leader in Hoenn with a nice mustache.
- Chick Magnet: He's very popular with the ladies to the point of having a large harem.
- Climax Boss: Juan is the final Gym Leader Ash has to defeat in order to enter the Hoenn League. Not only that, he proves to give Ash a tough time with his unique battle rules and synergy with his team.
- Cool Old Guy: He's a relaxed older gentleman to anyone he meets.
- Cutting Off the Branches: Becomes Ash's last Hoenn gym leader instead of Wallace, to tie in with Emerald.
- Eyes Always Shut: His eyes are usually closed for the most part especially during battles or his water performances.
- Healing Factor: His Milotic big time. Ash struggled to defeat it due to it constantly using Recover over and over agin.
- Graceful Loser: He takes his defeat to Ash pretty well and congratulates him for winning as well as giving him the Rain Badge.
- Making a Splash: He specializes in using powerful Water Pokémon in battle.
- Mythology Gag: His team is a replica of Wallace's Ruby and Sapphire team.
- Retired Badass: He was once won the Grand Festival when he was younger and earned a Ribbon Cup. Later on he would retire as a coordinator and become the Sootopolis gym leader.
- Real Men Wear Pink: He was a former Top Coordinator.
- Signature Mon: Milotic. It's not only his most powerful Pokémon, but he also used it to win the Grand Festival as well as be the hardest for Ash to defeat.
- Voiced in Japanese by: Toshiyuki MorikawaVoiced in English by: Sean ReyesVoiced in Latin American Spanish by: José Luis Rivera
Former leader of the Sootopolis gym, and Juan's apprentice.
Kanto Battle Frontier
These are the tropes pertaining to the characters associated with the Battle Frontier.
- Adapted Out: None of the Frontier Brains exploit their various stipulations that gave the Frontier a challenging experience in the first place (probably because some of the stipulations can be hard to translate in anime form; looking at you, Greta); once Ash finds a facility, he gets to challenge the Frontier Brain right off the bat. The Silver Symbols are omitted, as well; Ash gets the Gold Symbol immediately after defeating one.
- Compressed Adaptation: The idea of setting the Frontier in the Kanto region is, on paper, a way to advertise both Emerald and FireRed and LeafGreen at the same time.
- Rank Up: A trainer that actually manages to beat the Battle Frontier is given the chance to become a Frontier Brain him-/herself. Scott actually offers this to Ash, only for the latter to turn it down.
- Voiced in Japanese by: Koichi SakaguchiVoiced in English by: Frank Frankson (4Kids), Bill Rogers (current)Voiced in Latin American Spanish by: Luis Alfonso Padilla
The owner of the Battle Frontier, he first appears as a witness to Ash's battle against the Elite Four member (and substitute Viridian leader) Agatha. Although Ash lost, Scott saw potential in the young trainer, and recommends that he take on the Frontier.
- Ascended Extra: In Emerald, he really doesn't do much. Here, he's present in each and every one of Ash's Frontier matches.
- The Chooser of The One: On the lookout for strong trainers, and sees that Ash has potential.
- Drives Like Crazy: He and Birch would probably get along pretty well.
- Hawaiian-Shirted Tourist: The fact that he even travels all over the place certainly gives him the image of one.
- Hidden Eyes: Averted, as this is perhaps the only adaptation where Scott removes his shades (although only once) to show his eyes.
- King Incognito: When Ash first meets him, Scott is looking for strong trainers, and tells him about the Battle Frontier. He later shows up for all ten of Ash's matches against the seven Frontier Brains (including his rematches with Anabel and Brandon), but doesn't reveal his status as the owner of the Battle Frontier until Ash is getting ready for his last match with Brandon.
- Nice Guy: He's friendly and well-mannered to pretty much everyone, and is understanding when Ash opts to continue traveling and challenging gyms rather than join him as a Frontier Brain, telling him the offer will always be open.
- Sigil Spam: The Gen III Battle Frontier logo, pasted on his car as well as his PokéNav.
- Voiced in Japanese by: Nobuyuki HiyamaVoiced in English by: David WillsVoiced in Latin American Spanish by: Jorge García
- Voiced in Japanese by: Sanae KobayashiVoiced in English by: Sonny DeiVoiced in Latin American Spanish by: Mildred Barrera
- Fangirl: Self-professed fan of Chuck and Brawly, explaining her preference for fighting-types.
- The Unreveal: Greta's roulette wheel (which decides the number of Pokémon the Brain and her challenger will use) has an option that can go up to three Pokémon per battle. But since Ash's spin landed the wheel on a 2-on-2 instead, the audience never found out what her 3rd Pokémon actually was.
- Voiced in Japanese by: Kenta MiyakeVoiced in English by: Bill RogersVoiced in Latin American Spanish by: Irwin Daayán
- Voiced in Japanese by: Atsuko TanakaVoiced in English by: Emily WilliamsVoiced in Latin American Spanish by: Laura Ayala
- Adaptational Nice Guy: She was an arrogant Sadist in the games, whereas she's an aloof but kind young lady here.
- Aloof Dark-Haired Girl: She gets the personality to play this trope straight, unlike in the games.
- Bare Your Midriff: Her outfit exposes her belly.
- Crush Blush: Gains one whenever Brock complimented her.
- Eyes Always Shut: Not her, but it's the main reason she likes Brock.
- Glass Cannon: Scott notes how her idea of battle is all offense.
- Onee-sama: Her assistants called her such in the original Japanese.
- Voiced in Japanese by: Nachi NozawaVoiced in English by: Eric SchusslerVoiced in Latin American Spanish by: Jorge Ornelas
- Cool Old Guy: Since their match takes place in the span of an entire forest, there is a lot of running among trainers and their Mons; Spenser has no trouble keeping up with either in spite of his age.
- Mid-Battle Tea Break: Offers Ash recess time so they can have lunch in the middle of their match.
- Voiced in Japanese by: Akiko KimuraVoiced in English by: Hilary ThomasVoiced in Latin American Spanish by: Rebeca Gómez
- Adaptational Badass: An odd, yet more conventional use of the trope in which she is the one who's become more badass rather than her party. In the games, she wasn't noted to have any kinds of special abilities and was essentially just a powerful trainer. In the anime, she possesses empathic abilities that allow her to command her team non-verbally.
- Adaptational Nice Guy: Anabel in the games was a big case of Good Is Not Nice - she's respectful and nice only to trainers who impress her with their battle skills, while taunting and looking down upon those who don't as people with "no talent". It's highly unlikely that the games' version of Anabel would help Ash, much less fall in love with him, after he lost to her.
- Adaptational Wimp: While her team is quite powerful for a psychic-type specialist such as herself, it has nothing on the Olympus Mons she commanded in the games.
- All Love Is Unrequited: She clearly has it bad for Ash, but being a Chaste Hero Oblivious to Love, he doesn't see the cues.
- Bifauxnen: Ash and friends didn't realize she was a girl thanks to her appearance and androgynous voice.
- Curtains Match the Window: Violet hair and eyes.
- The Empath: Can even mentally communicate with her Pokémon when she really gets into battle.
- Quickly-Demoted Woman: In the games she was the leader, and the strongest member of the Hoenn Battle Frontier. For the Kanto Battle Frontier in the anime, she's second-strongest to Brandon. That said, she's still quite powerful in her own right and gives Ash a hard time in their matches, being the only one in the Frontier other than Brandon to beat him (and without being pushed too hard - Ash only beat her Alakazam in a 3-on-3, partly just because it was tired from battling Corphish and Tauros). Plus, she doesn't have any legendaries to bolster her team like Brandon does.
- A Taste of Defeat: Ash's winning streak in the Frontier screeched to a halt with her. In their first match, she defeats Ash with only one of her three Mons knocked out.
- You Gotta Have Blue Hair: Violet, in fact.
- Voiced in Japanese by: Masayuki OmoroVoiced in English by: Craig BlairVoiced in Latin American Spanish by: Rolando de Castro (Advance Generation), Manuel Campuzano (Diamond & Pearl)
- The Ace: He's the strongest of the Frontier Brains, and owns the immensely powerful legendary golem trio. Many a trainer's Battle Frontier winning streak (including Paul's brother Reggie) ended against him. It took Ash gathering his original three starters (Squirtle, Bulbasaur and Charizard) and Brandon using a handicapped team for Ash to just BARELY manage to win against this utter beast of a trainer.
- Arc Welding: In DP, it was revealed that he indirectly caused Paul's Freudian Excuse.
- Barrier Maiden: He states his intent to have his three Regis become the new pillars that protect Regigigas after Hunter J destroyed/murdered the previous ones.
- Big "NO!": Yells these out whenever he disapproves of something.
- The Bus Came Back: Returns during the Snowpoint City episodes in the DP saga.
- Curb-Stomp Battle: He effortlessly defeats Paul in a full battle, and without allowing any of his Pokémon to be knocked out.
- Curtains Match the Window: His brown hair and eyes.
- Don't Call Me "Sir": He hates being called "Mister".
- Final Boss: Brandon is the final opponent of the Battle Frontier that Ash faces and definitely lives up to the title of "Pyramid King".
- Futuristic Pyramid: This version of the Battle Pyramid is a giant flying contraption which he uses to travel around.
- Genius Bruiser: The bruising mainly comes from his mons, but he is an accomplished Archaeologist and is knowledgeable in ancient history and language.
- Olympus Mons: Used to utilize the three Regis in his battles.
- Perpetual Frowner: He almost always has a stern-looking expression on his face. He does smile on several occasions, though.
- Scissors Cuts Rock: Protect is a move that blocks almost any move no matter how powerful. Yet Brandon's Regirock destroys Paul's Electabuzz's Protect with a really strong Stone Edge.
- Taken for Granite: The only human who was petrified by J's technology (as were his three Regis). Thankfully, Regigigas reversed it using Hidden Power.
- That One Boss: In-Universe. He's the only major, certified opponent so far who Ash had to battle thrice (though the first time, Ash was possessed by an evil spirit), he has three Legendaries, he was the only opponent Reggie could scarcely scratch (and the loss caused him to decide to quit training professionally), and he's only the second person known to have given Paul a Curb-Stomp Battle (the other is Cynthia). And when Ash did beat him, he was only using one of the Regi trio - the freshly-caught Regice. So yes, he qualifies for this.
- Third Time's the Charm: Ash only beat him on his third try.
- What the Hell, Hero?: He points out that the reason Ash got possessed by the evil king was because of Ash's arrogance and carelessness.
