Pokémon World Championship Participants
As A Whole
- Uncatty Resemblance: With the exception of Korrina and Tony, the majority of the challengers wears an outfit themed after the Pokemon type or Pokemon that they use.
The substitute Vermilion City Gym Leader.
- Bare Your Midriff: Wears a short green tanktop and matching green pants that shows her midsection.
- Brawn Hilda: Her superior is the Lightning American, so with her build that's as good as her Pokemon battling she could be a downplayed version of this.
- Confusion Fu: Her Electrode has specifically been trained with this fighting style in mind, allowing it to easily counter her opponent's own Confusion Fu.
- Dark-Skinned Blond: She's tanned and has light hair.
- Expy: She is named and modelled after Private Jenette Vasquez from Aliens.
- Human Hammer-Throw: The result of her Raichu grabbing Pikachu with its tail; though not referred to by any name, this could possibly be its execution of Seismic Toss- a potential type-coverage move that Raichu can learn in the games in which it's taught by a tutor or TM. Also unsuccessfully attempted on Gengar.
- Oh, Crap!: Her Raichu gets this expression when Ash's Gengar dodges its Thunderbolt, and remains that way for much of the battle as it becomes increasingly clear just how thoroughly outclassed it is.
- Shock and Awe: As the substitute gym leader she specializes in Electric types and is seen using Raichu and Electrode.
- Taking You with Me: Should her Electrode take enough damage, its ability Aftermath is triggered resulting in an explosion meant to catch the opponent and knock them out with it.
- Worthy Opponent: Surge's word about Ash makes Visquez take Ash's reputation as a challenger on a high note.
A trainer from Goldenrod City who specializes in Grass-types and challenges Ash during the Pokémon Orientation.
- Green Thumb: He uses a Meganium which has Razor Leaf and Solar Beam as two of its moves.
- Punny Name: Both he and his Meganium are named after a Comedy duo both in the Japanese series and the English Dub.
- His Japanese name Seiya and his Meganium's nickname Soshinium are named after Seiya and Soshina, two comedians who form the Japanese comedy duo Shimofuri Myojo. Ironically, Seiya also provided the voice for that character in the series.
- His English name Oliver and his Meganium's nickname Stanium are named after Oliver Hardy and Stan Laurel, two comedians who form the comedy duo Laurel and Hardy.
- Signature Move: Solar Beam. He mentions that until Ash, no trainer was able to withstand this attack.
- You Gotta Have Blue Hair: His hair is green with pink tips at the end to match his Meganium.
- Animal Motif: His outfit has a bull motif, matching how his Pokémon is a Tauros.
- Extra-ore-dinary: His Tauros knows Iron Head.
- The Leader: According to Goh's Pokédex, his Tauros is the leader of the pack thanks to features like it's build and its scarred horns.
- A Load of Bull: His signature Pokémon is Tauros and not to mention his Animal Motif.
- Non-Elemental: His only known Pokemon is a normal type.

- Alliterative Name: Kricketina Kylie in the dub.
- Animal Motif: Bugs. She even dresses up as a Kricketune.
- Berserk Button: She gets infuriated if people insult her cooking.
- Beware the Silly Ones: Despite her energetic character, Kylie holds a respectable ranking in Super Class of the World Coronation, so her status as a trainer is not to be taken lightly.
- Big Creepy-Crawlies: Her pokemon are all bug types.
- Cat Smile: Go with with her energetic personality.
- Cute Little Fangs: Has a slight prominent fang on the right side of her mouth.
- Genki Girl: Possibly the most energetic of Ash's Challengers barring Korrina, who moves around a lot with the aid of skates. This girl however is bouncing around the place on her own power alone.
- Shipper on Deck: Strongly towards Pinsir and Heracross when she sees how close they are.
- Supreme Chef: With the help of her Heracross, is able to cook up a stew (that she calls Kricketina Treats) as bait to lure Pinsir. It is so good that it gets stolen by Team Rocket.
- Bare-Fisted Monk: His only known Pokemon is Gurdurr, a fighting type..
- Bring It: His Gurdurr does one of these to Farfetdh's during their Coronation Match.
- Dishing Out Dirt: His Gurdurr knows High Horsepower (a Ground-type move).
- Gentle Giant: Is shown to be a pretty big and tough miner but still shows great care for his Pokemon after losing to Ash.

- Bare-Fisted Monk: His Gallade is part Fighting-type and knows Close Combat.
- Curb-Stomp Battle: Gives one to Farfetch'd in their first meeting. His Gallade is able to take it down in 2 hits while Farfetch'd is unable to even land one.
- Expy: To Tad from the Orange Islands. He battled Ash while he was dealing with an unruly Pokemon, sort of helping him reigning said Pokemon in, and then saying they'll have a rematch when Ash gets a better handle on the Pokemon. Unlike Tad however, he returns for a second episode. Though his appearance and Pokemon choice of Gallade reminds a few fans of Wally from Pokémon Ruby and Sapphire
- Oh, Crap!: After Farfetch'd gets fully motivated by Ash and starts a come back, Rinto not only is visibly surprised, as his Gallade flinches and even shivers after being hit consecutively three times!
- Psychic Powers: Gallade is part Psychic-type and knows Psycho Cut.
- Small Role, Big Impact: His first appearance and battle with Ash and Farfetch'd, short and swift it was, is what encourages Ash to try to get more in sync with it so they can battle better next time.
- Stealth Mentor: Apparently, tries to point what's wrong about Ash & Farfetch'd's team work, but, he spent a good part of the battle being dismissive and not actually telling the problem.
- We Will Meet Again: He promises Ash they will meet again for a proper battle once he and Farfetch'd improve their teamwork. He does nine episodes later.
- You Gotta Have Blue Hair: His hair is dark green and looks like Gallade's helmet.

- First Friend: Is this to Goh (well first friend really into Pokémon, that is).
- Goal in Life: To find Celebi.
- Green Thumb: His starter Pokémon is a Chikorita.
- Meaningful Name: Horace is Latin for "man of time", quite fitting for someone who wishes to hunt for the time-travelling Celebi.
- My Greatest Failure: He fell ill the day after meeting Goh and felt guilty for making Goh believe they weren't friends anymore. Upon finding Celebi's shrine, he wrote a letter for Goh to find to explain what had happened and even wished for Celebi to make him go back in time a year prior just to apologize.
- Small Role, Big Impact: Horace falling ill and being unable to meet up with Goh was what caused Goh to close himself off from people and become obsessed with capturing Pokemon to fill that void.

- Establishing Character Moment: Arrives riding his Hariyama shadowing Ash and glaring at him, asking him to move...so he can put his empty water bottle into the recycling bin.
- '50s Hair: He has an impressive pompadour, which also has what resembles a flat open palm in the front. In episode 64, he is constantly combing it while chatting with Ash and Goh.
- Face of a Thug: He has pointed teeth and a pompadour, but is actually a pretty nice guy. Episode 64 shows that the sharp teeth were inherited from his uncle.
- Like Father, Unlike Son: Or Uncle in this case. He is the polar opposite of his more Hot-Blooded uncle, to the point of objecting to his idea of how to capture Absol.
- Sore Loser: Subverted. He looks like he's about to pitch a fit after Ash beats him, going through the exact same movements from his Establishing Character Moment too, but he thanks him for a good battle instead.
- Uncatty Resemblance: His eyes, smile and clothes give him the look of a Garchomp...even though he doesn't have that Pokémon on him.
- Wake-Up Call Boss: He serves as this for Goh, being his first opponent with actual skill.

- Spy Catsuit: Jacqueline naturally wears one in the movie.
Information about him is found in Pokémon XY Anime Cast.
- Big Damn Heroes: He along with Ash and Goh rescue Chloe, Eevee and Dewgong from an angry Huntail who has trapped hem in a cave. He deals with the Huntail while Ash and Goh free her.

- Making a Splash: He has a Vaporeon that knows Hydro Pump.
- Small Role, Big Impact: While he only appears in one episode, he and his Vaporeon serve as the first step for Chloe and Eevee and deciding what she wants to evolve into, deciding to wait rather than jump to becoming Vaporeon.
