Kanto Gym Leaders
- Long Bus Trip: The only Gym that was visited during the Battle Frontier saga (which was placed in Kanto instead of Hoenn note ) was the Pewter Gym. Misty did travel with the group at the beginning of the arc, but she parted ways just outside of Cerulean City.
- Leitmotif: Played with. Expectedly, an arrangement of the Red, Blue and Yellow's gym battle theme is used in the anime, though is more directly linked to Determinator moments. As such though, it is still played during a few gym battles.
- One-Shot Character: Lt. Surge, Erika & Koga.
- Out of Focus: In the anime, compared to several other mediums (most notably Pokémon Adventures, where several were even Team Rocket agents). Even the Johto Gym Leaders (most of them, anyway) didn't get it this bad.
- Wakeup Call Boss: Ash got his first two badges without actually battling for them, and was able to use Pikachu's electrity as a failsafe (he did battle Brock, but surrendered before he got the badge anyway for good sportsmanship). Lt. Surge's Raichu beat them badly, forcing them to improve their technique and truly earn their victories.
The oldest of the Brocklings after Brock, Forrest is one of Pewter City's gym leaders, sharing the position with his parents. He finally becomes the sole official Gym Leader after passing a test posited by the PIA.
- Dishing Out Dirt : As the Pewter Gym Leader, he's a specialist in rock type Pokémon.
- Extra-ore-dinary: Steelix is a Steel-type.
- Reasonable Authority Figure: Takes his role as Gym Leader seriously, much more than his parents and still more than his brother does
Brock's father, who helped Ash's Pikachu to become stronger and he kept the Gym running while Brock was travelling until his second son Forrest took over.
- Adapted Out: Nowhere to be seen or mentioned (by name) in the novelization, which mentions that Brock's numerous brothers and sisters are only his half-siblings. It's worth noting that the novel is fairly revisionist in its depiction of events, so make of that what you will.
- Brick Joke: His debut has him sitting in the outskirts of Pewter City in a Lotus Position. In the Chronicles episode showing Brock's return to Pewter City, he's back in the same spot again. He even has the same disguise!
- Disappeared Dad: Who came back. While he's certainly proven himself a bit more responsible than his wife, she can still drag him along into irresponsibility. Most notable when he's pulled along on vacation with her (taking Ludicolo to carry the bags), leaving Brock to clean up their mess.
- Dishing Out Dirt: Rock-Type specialist. His Golem is proof of this.
- Epic Fail: In a battle to decide the fate of the Pewter gym, Flint uses his Golem...on a battlefield that was a pool of water. Obviously, Lola didn't have to put too much effort into winning the battle...
- Eyes Always Shut: Passed this on to all his kids.
- Like Father, Like Son: Apparently, Brock takes his weakness for girls from him, although this was only shown around Lola.
- One Steve Limit: Averted: we also have Flint of the Sinnoh Elite Four.
- Parents as People: A surprisingly good example - when he's not being neglectful or just plain stupid, he can actually be a thoughtful and loving father. For instance, according to Brock he's the one who gifted Brock his Onix on his son's tenth birthday - the two of them sat together on Onix's head to watch the sunrise, and Flint's Happy Birthday message made Brock feel it was the first time he truly had his father's recognition.
- Sickeningly Sweethearts: with Lola, to the point that even their own children are creeped out.
Brock's mother, who has attempted several times to turn the Gym into a Water-Type Gym.
- Absurdly Youthful Mother: Despite being the mother of teenage Brock and nine other children, she looks like she could be in her early twenties at best.
- Cat Smile: A more subtle example, as only the corners of her upper lip curl upwards. It gives her more of a childish expression than specifically resembling a cat.
- Dub-Induced Plot Hole: The dub claimed she was dead, then she appeared later with nary an explanation or even a Hand Wave.
- Making a Splash: She specializes in Water-Types and has attempted several times to turn the Gym into a Water-Type Gym.
- Meaningful Name: Her Japanese name, Mizuho, contains the characters for mizu, which means "water".
- Missing Mom: Until she suddenly came back...with every intent of remodeling the Gym, against the wishes of pretty much her entire family.
- Parents as People: She loves her children, but was clearly not fit to ever be a parent, as her mental state is too flighty and immature, causing her to become distracted with other things too easily, and doing things like leaving Brock in charge of his siblings without even considering the strain it would put on him.
- Really Gets Around: According to the novels by Takeshi Shudō, her many children are the product of numerous marriages and relationships which ended in divorce. However, considering the fact that the novels were created prior to her debut in the anime, along with all her children having a clear Strong Family Resemblance to Flint (with none of them sharing any real physical similarities to her), the canonicity of this is heavily debatable at best.
- Sickeningly Sweethearts: With Flint.
- Social Services Does Not Exist: Or else she (and even her husband) would have already received a call from them a long time ago.
Misty's eldest sister. Got a large role in two of the Chronicles specials, proving surprisingly popular in the process.
- Adventure Couple: With Tracey, although there's no clear indication they're an actual couple.
- An Ice Person: Dewgong is an actual ice type, and her Luvdisc uses Ice Beam.
- Bifauxnen: She's the "handsome prince" in the water show from the first season.
- Big Sister Bully: Is said by Misty to have been this in the past along with Violet and Lily, although by the time we meet her in the series proper she's already matured out of that position and ends up growing particularly close to Misty.
- Brainless Beauty: Played up a bit in the dub - the Valley Girl accent naturally doesn't help - but it's present to an extent in the original as well. Though she's actually a good deal smarter than she lets on.
- Canon Immigrant: Daisy, Violet, and Lily became Beauty-class trainers who can be fought at the Cerulean Gym in Let's Go.
- Character Development: Started off as a Flat Character like her sisters, but eventually developed her own unique personality.
- Crouching Moron, Hidden Badass: Sure, as the oldest, she didn't win the battling skills, but throw a pair of Cool Shades on her and suddenly she's an action heroine to be reckoned with, spearheading the mission to chase down Butch and Cassidy with her driving skills. Once the glasses come off, she of course freaks out and needs to team up with Misty in order to battle effectively.
- Dismotivation: Does not wish to do actual work, and is not above bribing gym challengers into completing household chores.
- Head-Turning Beauty: One-third of the Sensational Sisters.
- Imagine Spot: Notable for setting up a blatantly lying episode trailer that sent the shippers into conniption fits.
- Making a Splash: Water-type gym leader.
- Rapunzel Hair: Her blonde hair has waist length.
- Savvy Guy, Energetic Girl: Energetic Girl to Tracey's Savvy Guy.
- Shipper on Deck: Albeit in the most teasing, backhanded way possible. In fact, in the Cerulean gym's debut, all three sisters instantly ask Ash if he's Misty's boyfriend.
- Smash Sisters: We've only seen her battle once, and she holds her own quite well teamed up with Misty. Maybe it's just lack of effort?
Violet (Ayame) & Lily (Botan)
The middle siblings in Misty's family. Share several tropes with Daisy (above).
- Ballet: Violet is stated to be taking lessons in preparation for a stint as a model at the start of "A Date with Delcatty".
- Big Sister Bully: Are this when we first meet them, though their bullying is with their words and positions rather than anything physical. Lily in particular, being the second youngest and thus the most eager to assert their superiority.
- Floral Theme Naming: "Violet" and "Lily".
- Adaptational Jerkass: In the original games, he was a genuinely patriotic, if somewhat boastful, Flavor 1 Eaglelander. Here, he's just a flat-out bully. Even his Yellow Version counterpart is comparatively more mellow than that.
- Adapted Out: He doesn't have Voltorb or Pikachu like he does in Red and Blue and the remakes. Averted in Yellow.
- Affectionate Gesture to the Head: Pats Ash's head when he announces himself as the next gym challenger.
- The Brute: Surge is practically the largest human in the anime; his fighting style with his Raichu also reflects this.
- The Cameo: In Pokemon Journeys, over twenty years later, Ash visits the gym again for a PWC match. While Surge himself only appears in flashbacks due to being currently away, his subordinates tell Ash their gym battle has left quite the impression on their leader.
- Crossdressing Voices: Given that his VA is female in the Dub.
- Dark-Skinned Blond: Though it's more of a healthy tan.
- Defeat Means Respect: In Pokemon Journeys, this is apparently how Surge sees Ash nowadays. Surge's disciple and temporary gym leader, Visquez, says Ash's battle against Surge is an example to everyone at the Gym and Ash is considered a respectable opponent.
- Did Not Think This Through: As a gym leader, you'd expect him to have some understanding of the mechanics of stone evolution, namely that once Pikachu evolves into Raichu its moveset is stunted.
- Drill Sergeant Nasty: Possibly, judging by his attitude towards strength and power.
- Eagleland: Flavor 2. His new-earned respect for Ash (after defeating him) shows some Flavor 1, though - he's a bit of both with emphasis on the 2nd.
- Graceful Loser: All Gym Leaders tend to be this in the anime, but even now Surge's attitude made him the most surprising of the bunch.
- Gratuitous English: In the original Japanese.
- Jerkass: Insults Ash and his Pikachu, calling them weak and worthless.
- Jerk with a Heart of Gold: After Ash defeats him, he gains respect for the former.
- Large and in Charge: Is abnormally tall in the anime. Assuming his Raichu is drawn to scale, his height would be over eight feet. Some scales go to even being over ten feet tall◊.
- Precision F-Strike: Lets off a "Goddamn!" in the Japanese version.
- Shock and Awe: Raichu is Electric-type.
- Walking Shirtless Scene: Wears no shirt under his open vest. The original anime game sprite and official art work had him drawn from an angle where the front of his torso wasn't visible.
- Wake-Up Call Boss: Surge is remembered as the first Gym Leader who makes Ash work for his victory and doesn't just give him a badge for a good deed. The sheer intensity of Raichu's electric attacks demands that Ash strategies to defeat Surge.
- Adaptation Dye-Job: From the games' blue/black hair to dark green.
- Adaptational Villainy: In the games, Sabrina is not at all malevolent and actually dislikes battling. Here, she has Split Personality issues, nearly trapped the group in her dollhouse for the rest of their lives and at the start of the episode nearly made Ash fall to his death.
- Adapted Out: She doesn't have Mr. Mime or Venomoth from Red and Blue and the remakes, and her only Kadabra has not yet evolved into Alakazam.
- Creepy Doll: Her younger self looks like a doll, but is really the physical manifestation of the childhood she gave up when she discovered her psychic powers.
- Creepy Monotone: In the English dub she doesn't emote.
- Curb-Stomp Battle: She handily beats Ash's team with just her Kadabra.
- Defeat Means Friendship: Or to explain it in episodes in which Ash faces her in battle: Defeat means being doomed to spend an eternity playing with her Split Personality doll. Defeating Sabrina, on the other hand, ends up redeeming her (though it was done unconventionally - due to her telepathic link with Kadabra, neither of them were able to continue battling after Haunter made her laugh and reignited the flame of her human soul).
- Easily Forgiven: Despite pulling a HeelFace Turn, she's never punished for any of the evil she committed, likely because most writers and viewers don't think it right to punish someone for something their "evil side" did.
- Eerie Pale-Skinned Brunette: Part of her menacing demeanor.
- Emotionless Girl: Her state of being until Haunter and Ash helped her reconnect with her humanity, causing a Split-Personality Merge.
- Enfant Terrible: When she was a child, after developing psychic powers. She drove away her father, turned her mother into a doll, and became such a cold, emotionless perfectionist that even her childlike side split from her.
- Invincible Villain: She is never actually beaten. She (actually, her dad) gives Ash the Marsh badge because Haunter made her laugh and gave her back the human side that she lost years ago.
- Knight of Cerebus: No mistake, Sabrina was the first antagonist to appear as a genuinely evil and dangerous threat to Ash and his friends. Telling is how it took three episodes for Ash to get a badge from her and even then it was the typical "gesture of thanks", when Pikachu still struggled to put a dent in Kadabra. Even Blaine - whose pokemon are meant to be stronger than Sabrina's - was beaten fairly in only two episodes.
- Obviously Evil: As several tropes listed above indicate. Friendly looking she is not...until she turns good, that is.
- Psychic Powers: Yep. Not just simple spoon-bending, but teleportation and transmutation, as well.
- Psychopathic Manchild: Her split personality, manifested by a Creepy Doll.
- Redemption Earns Life: In more than one way - Ash's determination to beat her not only turned her good, but essentially saved her soul as well.
- She's Got Legs: Sabrina's miniskirt shows off her legs. Sure she has boots on, but damn.
- Split Personality: The Creepy Doll she has in the anime is actually what Sabrina was like before she discovered her psychic powers (cheerful, smiling, and always wanting to play).
- Adaptational Jerkass: Erika almost ended Ash's journey to the Pokémon league simply because he passively insulted her perfume. When he proves resilient about it, she submits to a battle and, after Ash saves Gloom, proves quite friendly (especially considering he got it in danger in the first place). Played With, as the one who banned him from the Gym was her subordinates and Erika states that she has to accept his challenge when he issues it, implying they may simply have been acting without her say so.
- Adaptation Dye-Job: From black hair in the games to blue. Perhaps as a Mythology Gag, her disguise as a store owner does have black hair however.
- Breaking Lecture: Tries this with Ash during their Gym Battle by criticizing his "lack of compassion" towards his Pokémon, either to demoralise him or to teach him a lesson.
- Berserk Button: Being very sensitive about perfume, talking about it in a negative manner is not only enough to earn her ire and violent dismissal, but also indirectly get banned from her gym, as Ash had learned the hard way.
- The Cameo: Appears briefly in the 20th movie battling Ash.
- Defrosting Ice Queen: Towards Ash. She initially thinks Ash is callous due to hating perfume and his supposedly harsh treatment of his Pokémon. Then he risks his life to save her beloved Gloom.
- Disproportionate Retribution: Apparently thinks that badmouthing her perfume shop is enough reason to ban challengers access to her Gym, or at least her staff do. She does accept Ash's direct challenge (and implies she has to), though, and give him the badge in gratitude for saving her Gloom's life.
- Green Thumb: She specializes in Grass types.
- Keigo: Speaks this way in the Japanese version.
- Sensory Overload: Her main Pokémon is Gloom, which invokes this with its horrible smell. This poses a problem Ash, as said smell is bad enough to knock Pokémon out.
- Shamed by a Mob: A bad example. While Ash was certainly rude insulting Erika's perfume, to have not only her, but her employees, Brock, Misty and Pikachu shaming him on it was certainly uncalled for and excessive.
- Team Rocket Wins: Actually fell victim to a rare instance, as the trio blasted her gym on fire and stole her perfume (only an essence of it however, namely Gloom's, which they did not appreciate). Since Ash had indirectly helped them trying to get into Gym, he took this badly.
- Yamato Nadeshiko: The looks and the outfit are played straight but the rest is played with. Being a gym leader, she can't be the subtle, submissive type and instead of arranging flowers, she battles with them.
- Adaptational Nice Guy: He's a lot more reasonable than his Torture Technician game counterpart and other Kanto leaders by miles.
- Adapted Out: An extreme case, as none of his Pokémon in Red and Blue and the remakes match his anime team. Averted/subverted when Yellow is considered, as he has a Venomoth that evolved from Venonat on-screen, and Golbat became a Canon Immigrant when in the Gen II games, his Elite Four team included Crobat.
- Big Brother Mentor: Towards Aya, his younger sister.
- Big Creepy-Crawlies: Venonat/Venomoth's is a giant gnat/moth.
- The Cameo: Receives a very brief dubbed one in BW 116, during a flashback about Charizard's past. Probably the very first time we saw one of the original Kanto gym leaders that aren't Brock, Misty or Giovanni.
- Flight: Both Venomoth and Golbat.
- Highly Visible Ninja: Lampshaded by Misty.
- Actually he called his younger sister Aya out on this. Though Koga's anime attire still wasn't particularly shady.
- Poisonous Person: He specialises in Poison types.
- Adapted Out: One of the most extreme examples of all the Kanto Gym Leaders. None of the Pokémon in Red and Blue and the remakes match his anime team. In Yellow, the only Pokémon he has from the anime is Ninetales. In GSC and the remakes, the only Pokémon he has from the anime is Magmar.
- Bait-and-Switch: When Ash and company helped Blaine save the volcano from exploding due to Team Rocket's freezing it, he offered Ash something special. Ash thought Blaine was going to give him a Volcano Badge, to which Blaine Face Faulted. Instead, Blaine offered to give him a rematch for the Badge.
- Bald of Awesome: Though he wears a wig much of the time (possibly vanity), he proudly displays his bald pate to Ash once he's been defeated.
- Dishing Out Dirt: Has Rhydon, a Ground/Rock type, to go against Ash's Charizard.
- Horn Attack: Rhydon's Horn Drill.
- Mythology Gag: A subtle one with his disguise: take away his wig and balding hair, keep the glasses and paint the fake mustache white. You get videogame Blaine! Justified since his design had reportedly changed several times during the development of the games.
- Only the Worthy May Pass: Blaine got sick of all the second-rate trainers who challenged the Cinnabar Gym when the island became a tourist trap, so he burned it to the ground. He now tests trainers with riddles to see if they're worthy of facing him. If they can solve the riddles, they get to face him.
- Phrase Catcher: "Not another riddle!"
- Playing with Fire: He specializes in Fire types.
- Stealth Mentor: Blaine revealed it is not only a gym leader's job to test battle competence, but their judgment as owners of Pokémon, stating gym leaders may indeed disqualify trainers if they push their Pokémon past the limit, such as when he already had Ash beat in their first battle when he had Magmar curbstomp Pikachu in a losing battle, he was waiting for Ash to throw in the towel and commended him for doing so.
- Use Your Head: Magmar's Skull Bash.
- Wake-Up Call Boss: Just like Lt. Surge, Blaine was by far the strongest Gym Leader Ash faced to that point. Even before he brought out Magmar, Blaine already had the upper hand as his Ninetales curb-stomped Squirtle and Charizard refused to battle. If Pikachu had somehow defeated Magmar, he likely would have lost to Ninetales.
- You Have GOT to Be Kidding Me!: Blaine's reaction when Ash thinks that Blaine's going to give him a Volcano Badge for stopping the volcano from exploding. Blaine actually gives Ash a rematch for the Badge.
Orange Islands Gym Leaders
- Action Bomb: His Electrode knows explosion.
- Actually, I Am Him: he reveals himself as the Navel Island gym leader after accompanying Ash on a climb up a mountain enclosed on the grounds. Misty and Tracey said they figured it out when they took the lift to the top of the mountain and didn't find anybody there.
- An Ice Person: His Nidoqueen knows Ice Beam.
- Big Creepy-Crawlies: Has a Scyther, a giant mantis.
- Nice Guy: He's very supportive of Ash, giving him pointers on how to pass the trials needed to qualify for his own gym and warning him when he was about to break the rules.
- Betty and Veronica: In the Orange Islands episode where the trio meet Rudy, Misty is Archie, Ash is Betty and Rudy is Veronica when Rudy tries to flirt with Misty and Ash gets jealous.
- Big Creepy-Crawlies: His Venomoth is a giant moth.
- Dance Battler: Something he's trained all his team to do.
- Demoted to Extra: Averted in The Electric Tale of Pikachu; he and Drake are the only members of the Orange Crew shown in that adaptation.
- Ditto Fighter (Type 3): All of the Pokémon he uses in battle are intended to match the types of his opponent.note The attacks of said Pokémon need not apply, however...
- Graceful Loser: Rather graceful for losing to Ash in both the battle and for Misty (though Ash doesn't get the second one).note
- Green Thumb: His Exeggutor (used to fight Bulbasaur) is grass-type.
- Knight Templar Big Brother: Part of the reason why he was so adamant about marrying Misty is because his sister wanted her in the family after Misty saved her from drowning.
- Making a Splash: His Water-type Starmie (used to fight Squirtle)
- Playing with Fire: Has a Fire-type Ninetails at the Gym
- Psychic Powers: Has a Psychic-type Alakazam at the Gym.
- Shock and Awe: Electabuzz (used to fight Pikachu). Starmie also uses Thunderbolt.
- Action Mom: Has a son on his own journey (Who is an Expy of Ash down to a Pikachu and Inexplicably Identical Individuals syndrome), and is a Gym leader.
- Dishing Out Dirt: Has a Marowak.
- Early-Bird Cameo: Odd gameplay example, she did a double battle with Ash well before the mechanic was introduced in the games.
- Energy Weapon: Alakazam's Hyper Beam.
- Identical Stranger: Mistook Ash for her son Travis.
Leader of the Orange Islands Gyms - and he proves it in Ash's longest-at-the-time fight (the first 6-on-6 ever seen in the show, to boot). His Dragonite as well. takes on four members of Ash's team (including Charizard and Pikachu) and nearly wins.
Dragonite also has 10 moves, which exceeded the limit of anyone at the time before the anime started to enforce the move-limit. This was done on purpose by the writers to make it seem even more undefeatable.
- Beam-O-War: His Gengar and Ash's Lapras get into one. It ends in a double knock-out, the first one in the series.
- Ditto Fighter: In the first round of six-on-six battling, Drake's Ditto takes on Ash's Pikachu. Pikachu wins because it has more stamina.Ash: They can copy Pikachu, but there's nothing like the real thing!
- Energy Weapon: Dragonite's Hyper Beam.
- Expy: Rather obviously based on Lance of the Elite Four.
- Shock and Awe: Electabuzz is an electric-type.
- Victory Is Boring: When introduced, he's become tired of his own invincibility and that no challenger has ever beaten him since his ascension. So you can imagine that when Ash defeats him, he gracefully praises the young trainer on his victory.
- Worf Had the Flu: Ash's Pikachu was only to defeat Drake insanely powerful Dragonite after it had already battled his Charizard, Squirtle, Tauros in a row and was visibly exhausted.
Johto Gym Leaders
- Adaptational Badass: As the first gym leader in the games, he was a real pushover (infamously he is the only gym leader who sports a team still in the single digits). Here he boasts an exceptional team that made Ash sweat to win his victory. His Pidgeot was actually winning against Charizard until Ash figured out its attack patterns.
- Big Damn Heroes: He first appears on a hang-glider, rescues Pikachu, and blasts off Team Rocket. Then introductions are made.
- Break the Haughty: Ash's victory is implied to have humbled him somewhat.
- Hoist by His Own Petard: In the final part of his match with Ash, his Pidgeot had Charizard outclassed in terms of speed. It moved too fast for Charizard to be able to counterattack...but it kept using the same attack pattern. That helped Ash figure it out, and when he had Charizard trap Pidgeot with a Fire Spin, it was all over.
- Hypocrite: He states how he hates the consensus that Flying types would always lose to Electric types due to a type disadvantage...and then subsequently patronizes Ash for using Chikorita, for no reason besides her type disadvantage. He backed it up, but it was still an egotistical thing to do, and was followed by Laser-Guided Karma (below).
- In a Single Bound: His Dodrio is a very good jumper.
- Inertia Is a Cruel Mistress: Ash beat him using the old "attack where he's going" shtick.
- Jerk with a Heart of Gold: He's boastful of the superiority of his chosen Pokémon type and self-righteous about his methods, but he's good at heart and even went out of his way to save Pikachu with no personal gain involved. He also gracefully accepted his defeat.
- Laser-Guided Karma: After boasting of the strength of his Flying types, his Hoothoot takes out Ash's Chikorita easily; following that, his first two Pokémon are both defeated by Pikachu.
- Achilles' Heel: His Scyther can use Swords Dance to create the perfect shield from Fire type attacks, except those coming from directly above, which Ash exploits to defeat him.
- Arrogant Kung-Fu Guy: As Falkner, Bugsy boasts about his Pokémon specialty's superiority.
- Didn't See That Coming: Bugsy is shocked when Ash exploits the vulnerability resulting from Scyther's use of Swords Dance.
- Adapted Out: His Kakuna in the games is replaced by a Spinarak in the anime.
- Big Creepy-Crawlies: He raises Bug type Pokémon, bigger than normal bugs.
- Adaptational Nice Guy: In the games, Whitney was even more insufferable due to throwing a tantrum and initially refusing to give you a badge when you defeated her. Here, she's a Graceful Loser and willingly gives Ash the Plain Badge.
- Ascended Meme: Rarely was there ever a player who didn't get through her Clefairy on the first try, only to have their entire team clobbered by Miltank. Guess what happened to Ash the first time he battled her?
- Crouching Moron, Hidden Badass: She seems silly and playful, and her Nidorina and Clefairy go down quickly, but she's still the only Johto Gym Leader who Ash ever actually lost against in an official battle (his first battle with Pryce was unofficial and his first bout with Clair was interrupted by Team Rocket's thievery, so it doesn't technically count despite her having the edge).
- Nice Girl: She a bit a ditz, but she's real sweetheart and even though her second match with Ash had taken place outside the Gym, Whitney still accepted her defeat as official and awarded Ash the Plain Badge.
- Non-Elemental: Clefairy and Miltank. Clefairy would become a Fairy type later.
- No Sense of Direction: Gets lost in her own home town.
- The Bus Came Back: Returned in "For Ho-Oh The Bells Toll".
- Psychic Powers: Ghastly's Confusion and Haunter's Hypnosis.
- Reasonable Authority Figure: He has little reason to believe that Ash truly saw Ho-Oh (a Pokémon last seen three centuries ago), but he doesn't completely dismiss the notion and later, impressed by Ash's victory and "spirit", he concedes his challenger may indeed have seen Ho-Oh. He's also quite forgiving of their disturbing the Pokémon that live at the Burned Tower.
- Recurring Character: He even gets one guest appearance in the "Master Quest" season.
- Adapted Out: Chuck's Primeape in the games was replaced by a Machoke in the anime.
- Badass Normal: He can fight and train with his own Pokémon, but he's also...
- Brilliant, but Lazy: Thus, he's let himself go, tiring easily and having put on a little weight.
- Bruiser With A Soft Centre: Chuck and his Machoke not only embody this trope, they're proud of it.
- The Bus Came Back: He returns from a '''LONG''' bus trip and reappears in Journeys Episode #39.
- Catchphrase: He constantly tells his Pokemon to "focus their energy" and not give up when they're weakening.
- Hot-Blooded: Likely one of the most hot-blooded Gym Leaders in the entire series.
- Improbable Hairstyle: The way the hair on the back of his head sticks up.
- Long Bus Trip: With 915 episodes between his appearance in the Original Series and Pokemon Journeys, Chuck actually holds the record for longest absence between appearances for human characters.
- Making a Splash: Poliwrath is a Water-type.
- The Mentor: Has many students, the most notable two we know of being Brawly the Gym Leader of Dewford Town (in Hoenn) and Bea.
- Adapted Out: Sort of. She only uses one Magnemite in the anime, rather than two as in the games.
- Adaptational Badass: In the games, she's really shy and has trouble speaking. In the episode "Nerves of Steelix" of the anime, she jumps off from a cliff straight onto her Steelix's head, and doesn't even show a scratch. She's also a very aggresive Pokémon trainer, something you would never think of when playing the games. She's still a nice, cute girl outside of battle, though.
- Badass Adorable: She's a cute, gentle girl, but don't let that fool you. She doesn't hesitate to try and wipe out Ash's Pokémon party with her almighty Steelix. And even that of Flint from the Sinnoh Elite Four.
- Big Damn Heroes: For once, Team Rocket succesfully kidnap Ash's Pikachu near Olivine City, and Ash can't do anything about it. Seems like Jessie, James and Meowth are being thrown a bone after all these episodes, right? Wrong! Suddenly, a Steelix appears out of nowhere to stop these guys on their feet. Right after that, Jasmine joins in by making a jump that would destroy any normal person's legs and orders Steelix to send Team Rocket flying with an overpowered Iron Tail attack. Ash gets Pikachu back and thanks Jasmine, who reminds him there's a heated battle awaiting both of them back at the gym.
- The Bus Came Back: Makes a one-episode appearance in the "Diamond and Pearl" series.
- Characterisation Marches On: Was a borderline Shrinking Violet in her first episode. When she reappears, she's clearly taken a level in confidence and is more headstrong than before. Justified in that her Ampharos was terribly sick at first, leaving her concerned for its safety above all else.
- Extra-ore-dinary: She trains Steel types.
- Head-Turning Beauty: It's implied In-Universe that a chunk of the trainer community sees her as a good-looking gym leader, because she's nicknamed as "the fighting beauty" or something along those lines. Apart from the alias, no one ever comments on her beauty, though (besides Brock, that is).
- Hot-Blooded: Depending on the situation. She's calm and polite most of the time, but when it comes to a Pokémon battle, it's like someone put her on flames. She seems a totally different person.
- Made of Iron: She seems unfazed when she jumps on top of her Steelix's hard head from a cliff. But what did you expect? Her specialty is Steel types.
- Rapunzel Hair: In contrast with Whitney, Jasmine has quite the curtain of brown hair behind her. It goes past her waist, and sometimes it even reaches her butt. It not only has a large length, but a big volume as well, as demonstrated in the episode "Nerves of Steelix": when Magnemite is thrown all the way back to the gym wall, Jasmine's hair is completely blown around, giving quite the show, even if briefly.
- Recurring Character: She appeared multiple times in Johto, and even had a guest appearance in Sinnoh (to correspond with her cameo in the games).
- Sempai/Kohai: As a gym leader, Jasmine's duty is to teach Janina, a very young Pokémon trainer, how to battle. Janina is enthusiastic about connecting with her Onix so they can battle effectively, but completely misunderstands one of Jasmine's teachings: she thought Jasmine wanted her to eliminate Onix's weakness against water with wax, instead of talking with him so they could come up with proper defense strategies. When Jasmine notices this, she gets pretty angry, which stands out in comparison with her depressed state in the episode "Fight for the Light". Fortunately, Janina eventually understands what Jasmine was talking about and makes a strong connection with Onix to defeat Team Rocket. This appears to settle things between master and student.
- Shrinking Violet: Played with. She only acts hesitant and reserved when her Ampharos is sick (that is, in the episode "Fight for the Light"). In the other episodes, she's surprisingly outgoing and even aggresive when it comes to Pokémon battles.
- Signature Headgear: She wears a pair of cute, spiked pigtails pointing upward. Always pointing upward, no matter the pose or situation. She uses orange orbs to set them in place. These orbs being orange is no coincidence: Jasmine's name in Japanese is Mikan, which means "orange".
- Silk Hiding Steel: Puns aside, she's an elegant Girly Girl with the willpower to slaughter any Pokémon trainer she comes across. Even if they're supposed to be stronger than her (Flint from Sinnoh's Elte 4).
- Adaptational Jerkass: In the games, he's a perfectly pleasant and decent man. Here, he's a Jerk with a Heart of Gold.
- Cool Old Guy: Once he mellows out a little.
- Defrosting Ice King: He was a cold trainer due to his Freudian Excuse, but once he reunites with his Piloswine, he mellows out.
- Dishing Out Dirt: Piloswine is a Ground-Type.
- Early-Bird Cameo: He appears briefly in "Rage of Innocence" before having his full introduction in the following episode.
- Freudian Excuse: As a boy, he loved Pokémon dearly and was a skilled trainer. One day, he and Piloswine faced a tough Fire type, and Pryce's attempt to keep his friend from getting hurt only resulted in both of them being badly burned. While he was recovering, Piloswine up and left and never returned, leading Pryce to believe it had abandoned him for losing and subsequently hardening his heart towards Pokémon. Only after meeting Ash was it revealed that Piloswine had actually gone to get special herbs for healing burns, but ended up frozen in ice for years, leading to Pryce's My God, What Have I Done? realisation.
- Human Popsicle: His Piloswine was frozen for decades in a block of ice.
- An Ice Person: He specializes in Ice-Type Pokémon.
- Jerk with a Heart of Gold: Even in his "hating Pokémon" period, his softer side wasn't gone, just...buried, way deep down.
- Tender Tears: When he realizes that he was wrong about Piloswine, and again when Piloswine recognizes him despite his changed appearance.
- Use Your Head: Dewgong's Skull Bash.
- The Ace: The best of the best in Johto Gym Leaders, and arguably the most powerful trainer Ash faced up to that point aside from Prima. She's shown to be too strong for Ash's normal team, and he has to call in some of his most powerful 11th-Hour Ranger Pokemon to stand a chance.
- Adaptational Nice Guy: Her anime personality is far nicer than her game one.
- The Bus Came Back: Returns for a guest appearance in BW136, and battles Iris at the end of the Best Wishes! Saga. Interestingly, she is the first Gym Leader guest character to return and have met with all different traveling companions of Ash because Brock is no longer a main companion after the end of Diamond and Pearl.
- A Day in the Limelight: She has a five-episode arc.
- Curb-Stomp Battle: In Ash's first match with Clair, he used his regular team. Although Team Rocket interrupted the match, it was clearly heading this way in Clair's favor. When they had a rematch, Ash had to change up his team and bring in some of his best 11th-Hour Ranger Pokemon to have any hope of winning. Even then, he only won through some very creative tactics.
- Energy Weapon: Gyarados, Dragonair's and Kindgra's Hyper Beam.
- Extra-ore-dinary: Dragonair's Iron Tail.
- Making a Splash: Kingdra & Gyarados are water-types and Dragonair's Rain Dance causes raining.
- Palette Swap: Her Druddigon is shiny.
- Shock and Awe: Dragonair's Thunder Wave.
- 10-Minute Retirement: In her first episode, she refused to do anything (including perform the tri-annual ritual required of her) while her Dratini was shedding. It actually turned out to be in the process of evolving.
- You Gotta Have Blue Hair: As the trope name implies, she has blue hair.
