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.
- Signature Mon: Nosepass is her main Pokémon ace, being the final exam for Ash and Pikachu to master Iron Tail.
- 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.
- Curtains Match the Window: He has blue eyes that matches with his sky blue hair.
- Eyes Always Shut: He has a Makuhita, which always shuts its eyes until it evolves into Hariyama.
- 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.
- Nigh-Invulnerability: His Machop is able to absorb dozens of attacks from Taillow and Treecko due to the fact that Brawly had trained his Pokémon to roll with the waves if they fall off their surfboard. Nevertheless, it gets worn out during its battle with Treecko and is beaten by the Wood Gecko Pokémon.
- Signature Mon: Makuhita is his main Pokémon battler, and it pulls a last minute win over Treekco by evolving into the stronger Hariyama, reminding Ash to never underestimate his opponents.
- 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.
- The Worf Effect: Brawly's formerly near invincible Machop is easily outmaneuvered by Treecko and then pummeled by Corphish's Bubble Beam in the rematch to show off Ash's training.
- 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.
- Berserk Button: After his Magnemite and Voltorb are beaten in one blow each, he angrily orders Magneton to unleash a Zap Cannon and the Electric/Steel-type is also mad as it unleashes the attack. Ash simply orders Pikachu to use Thunder which powers through the attack and K Os Magneton.
- Cool Old Guy: He's old but energetic and fun, trolling Ash and friends with his animatronic Pokémon.
- Curb-Stomp Battle: He unintentionally gets beaten by a fever stricken Pikachu with Wattson's Magnemite and Voltorb falling to a single Thunderbolt each while Magneton is beaten by Thunder.
- 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.
- Signature Mon: After he lost badly to Ash, Wattson ends up befriending a wild Electrike who, after they stop Team Rocket from stealing Pokémon, decides to be his new Pokémon partner. Wattson's Electrike reenergizes Wattson with new confidence and evolves into Manectric in Wattson's next appearance. Manectric would eventually define itself as Wattson's true ace by defeating Ash's Torkoal and giving Wattson redemption.
- Theme Naming: He has an assistant named, well, Watt.
- Trap Master: His gym is tricked out with various traps. While they're mostly just for amusement (not only for him, but for visitors as well), Wattson claims that the traps should keep challengers on their toes.
- 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.
- Counter-Attack: Her Pokemon know a number of attacks to deflect or thwart her opponents' offense, like Reflect, Smog and Yawn.
- 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 Corphish.
- 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. Flannery neglected to clean up the battlefield after her previous opponent left it full of holes from Dig, forgot where her grandfather put her Gym's badges and didn't even realize that she couldn't make substitutions during her battle with Ash.
- Fiery Redhead: She's impulsive, outgoing and energetic, able to improvise quickly during her match with Ash.
- Heiress To The Dojo: She inherited the Gym from her grandfather after his retirement.
- Naïve Newcomer: Ash is one of Flannery's first opponents 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.
- Signature Mon: Due to her love of Overheat, her main Pokémon battler is Torkoal, the only Pokémon on her team that actually knows that move.
- Tomboyish Ponytail: She's a fiery hot tomboy and thus has fiery ponytail to match.
- 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)
- Didn't Think This Through: Orders his Slakoth to use Blizzard (an Ice-type move) against Torkoal's Flamethrower. After a second of collision in mid-air, Slakoth is overpowered and knocked out.
- Good Parents: He's a good dad to his kids, which more than can be said about the other fathers who are conspicuously absent from their kids' lives. His son, in particular, worships him as a great trainer.
- 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.
- Recurring Character: Due to being May and Max's father, he has more appearances to his name than any other Hoenn Gym Leader.
- Signature Mon: He uses the Slakoth line as his battling Pokémon, and thus Slaking is his most powerful and iconic Pokémon at hand.
- 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.
- Signature Mon: Subverted with Skarmory. She is first seen flying on a giant Skarmory, but never actually chose it her Gym match with Ash. Instead, her real signature Pokémon in the anime is a Shiny Swellow, a formidable final opponent that nearly defeated Ash's Swellow had it not been for Ash's quick thinking tactic.
- 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.
- Signature Mon: They each have a Meteorite Pokémon as their Pokémon partner. Liza's partner is Lunatone, and Tate's partner is Solrock.
- Voiced in Japanese by: Show HayamiVoiced in English by: Sean SchemmelVoiced in Latin American Spanish by: César Arias
- 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.
- Graceful Loser: He takes his defeat to Ash pretty well and congratulates him for winning as well as giving him the Rain Badge.
- Healing Factor: His Milotic big time. Ash struggled to defeat it due to it constantly using Recover over and over agin.
- 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 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
The former Leader of the Sootopolis Gym, and Juan's apprentice. He initially was the Champion with Juan filling in for his duty during the AG-BW era, but lost the position to Steven around XY.
- Curb-Stomp Battle: Implicitly lost his battle against Ash in JN105 rather quickly.
- The Bus Came Back: He makes a return in Journeys in JN105, the episode featuring the anime debut of his niece, Lisia.
- Making a Splash: He specializes in the Water-type, and owns a Milotic, Swampert, and Walrein.
- Mythology Gag: His usage of Swampert and Walrein is a nod to the World Tournament in Pokémon Black 2 and White 2.
- Narcissist: He gets annoyed when Ash doesn't remember who he is in Journeys, refuses to let him leave until they have a battle, and becomes jealous when Ash shows that he does remember Steven Stone.
- Same Character, But Different: His personality in Journeys is completely overhauled from how it was in Diamond and Pearl. During the Wallace Cup arc, he was portrayed as kind, wise, and relatively humble despite his status, while Journeys makes him far more petty, flamboyant, and egotistical.
- Signature Mon: His ace is Milotic, getting displayed several times throughout the Wallace Cup and being the last Pokémon used in his battle with Ash.
- The Worf Effect: He claims to be an equal to Steven Stone, one of the strongest trainers in the world (and despite his new narcissistic personality in Journeys, this holds weight as he's a former Champion himself). He still loses to Ash in their battle to show how powerful the latter has become.
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
The Frontier Brain of the Battle Factory, which is located near Cerulean City. When Ash comes to challenge him, Noland allows Ash to choose which of the former's factory Pokémon he desires to have a 1-on-1 battle against. However, Ash ends up picking to battle the Articuno that Noland managed to befriend. Noland provides the Knowledge Symbol to those who defeat him.
- Androcles' Lion: Befriended a wild Articuno after he saved its life.
- Signature Mon: Articuno. Noland has many regular Pokémon at hand, from Venusaur to Machamp to Camerupt. But he is most associated with Articuno because Ash chose it as his opponent Pokémon, leading to an epic battle that sees Ash's Charizard narrowly defeating Articuno, giving Ash's first victory over a Legendary Pokémon.
- Unexpected Character: In-universe, not a single person present (except probably Noland himself) expected Ash to choose Articuno as his opponent in their Frontier match.
- Voiced in Japanese by: Sanae KobayashiVoiced in English by: Sonny DeiVoiced in Latin American Spanish by: Mildred Barrera
The Frontier Brain of the Battle Arena, which is located near Saffron City. Greta in the anime is made a Fighting-type expert, and when Ash comes to challenge her, he has to spin a roulette to see if he will be taking her on in a 1-on-1, 2-on-2, or 3-on-3 Pokémon battle. He ends having a 2-on-2 against her. Greta provides the Guts Symbol to those who defeat her.
- Bare-Fisted Monk: Unlike the games, she clearly specializes in Fighting-type Pokémon.
- Fangirl: Self-professed fan of Chuck and Brawly, explaining her preference for fighting-types.
- Hot-Blooded: Like Ash, she is incredibly passionate about battling and is always in high spirit.
- One-Shot Character: She only appears in her debut episode.
- 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
The Frontier Brain of the Battle Dome, which is located near Lavender Town. Tucker in the anime is a famous superstar who shows off in front of a large stadium audience. He faces off against Ash in a Double Battle where he puts to use his strategy of combining Fire and Water into a fusion attack; a tactic that May puts to use for her Contest battles. Tucker provides the Tactics Symbol to those who defeat him.
- Ambiguously Gay: He's incredibly flamboyant in appearance and personality, and gives very romantic descriptions of Pokémon moves. But his sexuality is left unmentioned.
- Agent Peacock: Despite his flamboyant appearance and hammy attitude, he gave Ash one hell of a battle.
- Dual Boss: Faces Ash down in a Double Battle.
- Hoist by His Own Petard: His Arcanine and Swampert are beaten when Ash's Corphish and Swellow use their own Combination Attack on them.
- One-Shot Character: Only appears in his debut episode.
- Voiced in Japanese by: Atsuko TanakaVoiced in English by: Emily WilliamsVoiced in Latin American Spanish by: Laura Ayala
The Frontier Brain of the Battle Pike, which is located near Fuchsia City. When Ash comes to challenge her, Lucy faces off against him in a 2-on-2 utilizing serpent-like Pokémon. She also owns a wide variety of Pokémon who all have closed eyes, which plays into why Lucy develops a crush on Brock. Lucy provides the Luck Symbol to those who defeat her.
- 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.
- Always Someone Better: Her Seviper easily crushes Jessie's Seviper in a battle, reminding Ash that she won't be a pushover like Team Rocket.
- Animal Motif: Snakes. Her introductory episode is even titled Queen of the Serpentine.
- 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.
- Has a Type: It is implied that at least part of the reason she has a crush on Brock is because of his Eyes Always Shut. When she returns home at the end of the episode and is greeted by all her other Pokémon, they have similar eyes as Brock, and she comments she met someone whose eyes reminded her of them.
- Onee-sama: Her assistants called her such in the original Japanese.
- One-Shot Character: Only appears in her debut episode.
- Signature Mon: Seviper. Her outfit is modeled after Seviper and it's her easily her most trusted Pokémon.
- Snakes Are Sinister: Subverted. Lucy in the anime is quite nice and she even has a beautiful Milotic on her team.
- Voiced in Japanese by: Nachi NozawaVoiced in English by: Eric SchusslerVoiced in Latin American Spanish by: Jorge Ornelas
The Frontier Brain of the Battle Place, which is located on an island near the Seafoam Islands. Spenser in the anime appears to be an expert at naturesk Pokémon, such as utilizing Grass-types. He's first introduced helping Ash out with his Sceptile, who needed comfort after a love rejection broke his heart. Once it's time for battle, Spenser faces off against Ash in a 3-on-3 where the trainers can run along with their Pokémon in order for the battling to take place amongst the natural surroundings. Spenser provides the Spirits Symbol to those who defeat him.
- 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.
- Friend to All Living Things: He lives a simple life to appreciate the wonders of the natural world, and his knowledge helps Sceptile get over his broken heart.
- 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
The Frontier Brain of the Battle Tower, which is located near Tohjo Falls. In the anime, Anabel is made a Psychic-type expert to the point of being able to telepathically speak to her Pokémon through her mind, and her role as the leader of the Frontier Brains was given to Brandon. Anabel faces off against Ash in two 3-on-3 battles due to Ash losing the first match against her. The time that Anabel spent interacting with Ash, such as witnessing how much he cares for his Pokémon, is also what results in her developing a crush on him. Anabel provides the Ability Symbol to those who defeat her.
- 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: Unlike in the games, she's not the leader of the Battle Frontier (that role going to Brandon instead). Her team also lacks the Olympus Mons she commanded in the games, even though her team is quite powerful for a Psychic-type specialist such as herself.
- 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.
- Signature Mon: Espeon is her favorite Pokémon and thus her final Pokémon in her rematch against Ash. It nearly defeats Ash's Pikachu, only losing when Pikachu turns off the lights (preventing Anabel from seeing Ash's next move) and then uses Volt Tackle as the finisher.
- 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.
- 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 Frontier Brain of the Battle Pyramid, which because of the structure's ability to fly can be found at any location. Unlike the games, Brandon is made the leader of the Frontier Brains. Brandon is currently searching around ancient ruins in order to capture the legendary Regi-trio, which Ash first arrives at the Battle Pyramid when it was landed near Pewter City. However, his 1-on-1 battle with Brandon gets all weird when Ash's body ends up getting taken over by the spirit of the Pokélantis King. Brandon's battle against the spirit frees Ash, but the Pyramid King is left unimpressed by Ash's incompetence of getting taken over by a spirit, and holds off the rematch for a later time.
Later on when the Battle Pyramid is grounded at a valley ruin, Ash gets to have his 1-on-1 rematch with Brandon, but ends up losing, which leaves Ash to train some more until Brandon is free for a second rematch. Once Brandon is ready again, he notices the close bonds that Ash has with the four Pokémon (Pikachu, Bulbasaur, Charizard, and Squirtle) that Ash had since early Kanto, which Brandon instead challenges Ash to a 4-on-4 to battle against Ash's original squad, which Ash accepts. After a hard-fought battle, Ash finally manages to triumph over Brandon, and he's declared to have completed the Battle Frontier. Brandon provides the Brave Symbol to those who defeat him.
Brandon makes a return in Sinnoh where he flies his Battle Pyramid to Snowpoint City in order to investigate the nearby Snowpoint Temple that houses Regigigas. While there, he winds up having a 3-on-6 battle against Paul due to a past gripe regarding his older brother, Reggie, and ends up having to protect Regigigas against Pokémon Hunter J.
- 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.
- Adaptational Personality Change: In the games, Brandon is Hot-Blooded Thrill Seeker who theatrically invokes danger as a key part of adventure, while in the anime, Brandon is a Stern Teacher who severely chastises people for getting into danger.
- Adventurer Archaeologist: Not only is Brandon one of them, there's scarcely an appearance of his that doesn't involve ruins to be explored.
- 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:
- Ash's first match with him went down like this. Despite having a type advantage with Sceptile and being possessed by an evil king that played extremely dirty to win, Ash was defeated in one hit.
- It's revealed in a flashback that when Reggie challenged him, he lost without defeating a single one of Brandon's Pokémon.
- He effortlessly defeats Paul in a full battle, once again 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.
- "The Reason You Suck" Speech: He's prone to giving these out to people he's defeated.
- He points out that the reason Ash got possessed by the evil king was because of Ash's arrogance and carelessness.
- After effortlessly defeating Reggie, he lambasts him for his lack of a distinct quality or strength in his battling style, indirectly inspiring Paul's own obsession with strength moving forward.
- Lastly, he gives his biggest and most important one to Paul himself, tearing into his single-minded approach to power and for letting his emotions overtake him in battle. This speech, on the other hand, is the catalyst for Paul's Character Development, causing him to become significantly more respectful of both his Pokémon and opponents."NO! All wrapped up in the past. But, why then, do you walk the Pokémon path in the first place? Tell me why do you battle?"
- 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. Bulbapedia marks it as an error, stating that only Feint, Shadow Force and Phantom Force are supposed to get through Protect normally.
- Signature Mon: His Regi trio, Regirock, Registeel and Regice, are his most famous Pokémon on hand.
- 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.
