Ash Ketchum (Japanese: サトシ,Satoshi) is the main protagonist of the Pokémon anime series who has always dreamed of becoming a Pokémon Master. As soon as he turned ten years old, he rushed to Professor Oak's Laboratory to get his first Pokémon. He is the first character to be introduced in the series. Originally wanting to choose Squirtle, Ash ended up getting the Pokémon Pikachu, and left on his journey. It is currently unknown how old he is as of the latest episode, although he was canonically 10 from seasons 1-3. Though it is said in the first episode of the Best Wishes series (on the TV) that Ash is ten. Which means that, yes, the directors have confirmed that Ash is still 10.
At first, Pikachu did not obey Ash and kept running away, so Ash had to tie him up. After getting chased by a flock of Spearow, Ash attempted to save Pikachu from them; seeing Ash so determined to help him, Pikachu protected Ash from the Spearow by electrocuting the entire flock. From then on, Pikachu and Ash became best friends for life. As a completely unskilled trainer, Ash started his adventure while meeting his friends Misty and Brock and capturing new Pokémon.
Ash eventually defeated all the Gym Leaders in Kanto, allowing him to enter in the Pokémon League. Since then, he has continued to travel, make new friends such as Tracey, May, Max, Dawn, Iris and Cilan, challenging all Gym Leaders and capturing new Pokémon while still following his goal of becoming a Pokémon Master. Since this goal is so close to his heart, he sometimes acts a bit rash and rushes to the next battle he can as fast as possible. Ash is currently traveling in the Kalos region, with his new friends Bonnie, Clemont and his old childhood friend Serena. Ash's name in the Japanese version of the anime is Satoshi, likely after Satoshi Tajiri, the creator of Pokémon. It's unknown who Ash's father is, but according to 'Pokémon Live!', his mother dated Giovanni and was in his gang but took a better route in life when she met Ash's father.
When Ash Ketchum was a little boy, he was enrolled in Professor Oak's Pokémon Summer Camp where he would learn about the basics of Pokémon and being a trainer once he gets older. One day, a young girl named Serena, who was also enrolled, got lost in a forest while trying to look for her group and injured her knee after a Poliwag startled her. But at the very same moment, Ash, who was looking for the Poliwag, arrived and found her. He wrapped a clean, blue handkerchief with a PokeBall on each corner around her wounded knee to brace it. But she couldn't get herself up due to the pain, so Ash lent her his hand and helped her stand up, guiding her out of the forest and taking her back to the campsite.
Pokémon: Indigo League
Years later after attending Pokémon Summer Camp, Ash started his Pokémon journey when he had just turned ten years old. However, he overslept and when he got to the Professor's Lab, there were no more Starter Pokémon left. The Professor had one Pokémon left, but he said the Pokémon wasn't very friendly and released Pikachu.
Pikachu disliked Ash straight away and shocked him with its Thundershock attack. (This marks the start of his journey with Pikachu.) Later, Pikachu starts to trust Ash. Upon challenging various Gyms, Ash started finding traveling companions such as Brock and Misty. On his journey he regularly encountered the wacky trio Jessie, James and Meowth of Team Rocket, who kept trying to (and still try to) steal Pikachu. He finished in the Top 16 in the Indigo League Competition. During his journey he participated in a Pokémon race, was involved in a movie, got sucked into cyberspace and helped with the Moltres flame. Before heading to the Orange Islands, he picked up the GS Ball from Professor Ivy and bade goodbye to Brock who'd decided to stay with her.
Pokémon: Adventures on the Orange Islands
During this time, Ash was sent to the Orange Islands by Professor Oak on an errand to retrieve the mysterious GS Ball as the transporter cannot send it to Oak's lab. Ash found out that there were Gyms in the Orange Islands and decided to challenge them, winning a trophy for beating the Gym Leaders. During his time in the Orange Islands, Ash gained a new travelling companion in Tracey Sketchit, a "Pokemon Watcher", who observes Pokemon in their natural habitats and draws them in his sketchbook, and caught new Pokémon, Snorlax and Lapras, as well. He battled the Orange Crew in a style of battling much different than what he was used to. Eventually he battled Drake and became the next Orange League Champion. Upon Ash's return to his lab with the GS Ball, Professor Oak couldn't open it either and asked Ash to deliver it to his associate Kurt in Azalea Town in the Johto region, where there are also Gyms for the Johto League. Brock returned and Tracey remained behind to help Professor Oak at his lab. Team Rocket tried to catch Pikachu again, but they were stopped by Gary.
Pokémon: The Johto Journeys
Ash heard that there was a region called Johto and traveled there to find and catch new Pokémon unseen in Kanto. He battled the Gym Leaders there and caught the three Starter Pokémon, just as he'd done in Kanto. Brock returned and left Professor Ivy (for unknown reasons) and Tracey remained at Professor Oak's Lab. During this season, Ash won two badges for the Johto League, by facing Falkner of the Violet Gym and Bugsy of the Azalea Town Gym. He also catches a Shiny Noctowl, had another battle with Misty and said goodbye to his Charizard as he left it at the Charicific Valley so it could become stronger.
Pokémon: Johto League Champions
Ash won three more badges, but was delayed from having his sixth Gym Battle as the Gym Leader was preoccupied with caring for an ill Electric Pokemon, Ampharos, that fueled the lighthouse's power. Determined to get his Gym Battle, Ash traveled over to Cianwood City to get the medicine needed for Ampharos. Along the way he meets Whitney, Morty, Jasmine and Chuck, along with some new friends like Sakura, an aspiring Trainer and one of the 5 Kimono Sisters and reunites with Casey, whose Chikorita evolved into Bayleef. After his Gym Battle with Chuck, Ash and his mates traveled to the Whirl Islands on Chuck's suggestion to take part in the Whirl Cup Competition, a tournament for Water-type Pokémon.
Pokémon: Master Quest
During this season, Ash finally collected the remaining three badges to enter the Johto League by beating Jasmine, Pryce and Clair. He also met Lance and stopped Team Rocket's latest scheme at the Lake of Rage and brought a Larvitar back to its mother. In the Johto League, he battled his old rival Gary and finally defeated him, bringing their long rivalry to an end, then fought Harrison from the Hoenn region, who had a Blaziken, a Fire-Type Pokemon Ash had never seen before. To face it, Ash chose his trusty Charizard: the two Fire-Types fought fiercely, but ultimately Charizard fainted and Ash lost. (However, Charizard managed to wound Blaziken badly enough to prevent Harrison from using it in his next match, which led to his defeat.) Ash then decided to travel to the Hoenn region, but sadly both of his friends had to return home and thus would not be traveling with him this time.
Starting a new journey, Ash received new clothes from his mom, trading his familiar button-up shirt for a sleeveless hoodie, his green gloves for black ones and got a new cap. Breaking with what he'd done previously when he left for Johto, Ash left the rest of his team with Professor Oak and Tracey, intent on capturing new Pokemon in Hoenn, taking only Pikachu, his Starter, with him from home - the idea being to recapture the feeling of first leaving Pallet Town as a new Trainer. Upon arrival, he gained two new traveling companions in May, a beginner Trainer starting out on her journey with no clue what to do, and her younger brother Max, who has an extensive, impressive knowledge of Pokémon that far exceeds his years. Brock also returned, having finished his errands at home. Ash won his first three badges by the end of the season: the Stone Badge from Roxanne of the Rustboro Gym, the Knuckle Badge from a rematch with Brawly from the Dewford Gym, and the Dynamo Badge from Wattson of the Mauville Gym.
Pokémon: Advanced Challenge
Ash was eager to challenge more Gyms but was held up by May as she decided to be a Pokémon Coordinator. Ash encountered both Team Magma and Team Aqua, two villainous crime syndicates occupying the Hoenn region for the first time. Ash also won the Heat Badge from Flannery, the Balance Badge from Norman, May and Max's father, and a Feather Badge from Winona.
Pokémon: Advanced Battle
Before winning his last few badges, Ash was caught in a clash between Teams Magma and Aqua as they unleashed the legendary PokémonGroudon and Kyogre to reshape the world. Due to Pikachu's connection with Groudon, both teams were stopped and the legendary Pokémon returned to rest. After that, Ash beat the twin Gym Leaders Tate and Liza for the Mind Badge and Grand Festival winner Juan for the Rain Badge. Prior to entering the Hoenn League, Ash declined an offer from Professor Oak to trade in his current Pokémon with his previous captures on the grounds that his new team had earned it for themselves. He gained two new rivals in Morrison and Tyson, the former he would beat, but the latter he would lose to. He placed among the Top 8.
Returning to Kanto with Brock, May and Max, Ash was invited to partake in the Battle Frontier, battling Frontier Brains for Frontier Symbols. Upon encountering the first Frontier Brain, Noland and his Articuno, Ash left his friends for a quick bit while the Factory Head took Max and Pikachu up in his airplane, telling them "I had to make a phone call." Later that night as the gang was watching Noland's Pokémon eat dinner, they speculated which of Noland's Pokémon Ash would challenge: Max guessed Venusaur, May guessed Rhyhorn, but Ash, aiming high, boldly decided on Articuno. Wondering which of Ash's Pokémon he would use against a Legendary, the gang was excited when they saw his pick; Ash had gone straight to the top and brought in the big guns, calling in Charizard from the Charicific Valley to take on the Ice/Flying-type head-to-head. Despite the Type advantage being set against it, Noland's Articuno demonstrated its ability to quickly recover after taking direct hits from Charizard's Flamethrower and DragonBreath attacks and managed to gain an advantage over the fiery behemoth with an Ice Beam to the wingtip and repeatedly combining its Ice Beam and Water Pulse attacks, the latter move being strong enough to counter Charizard's newest move: Overheat. Ultimately though, Charizard managed to withstand Articuno's Steel Wing attack, and as the Legendary Bird came in for one last strike, it grabbed its wings in midair, stopping the attack before it could connect and topped it off with its signature Seismic Toss, knocking out Articuno for the win and earning Ash the Knowledge Symbol.
Pokémon: Battle Frontier
Ash battled all of the remaining Frontier Brains and earned their Frontier Symbols. The last Frontier Brain however, Pyramid King Brandon, proved to be more difficult for Ash to defeat; Their first official battle saw Brandon's Registeel defeating Ash's Torkoal in spite of a new move it learned. For their rematch, which would be four-on-four, Ash took a "back to your roots" approach, once again calling in Charizard but also this time bringing in Bulbasaur and Squirtle to reunite his trio of Kanto Starters. Putting them together with Pikachu, Ash formed a team of aces from his early days: pitting the four aces against Brandon's Dusclops, Ninjask, Solrock and Regice, he finally claimed victory and the final Frontier Symbol - the Brave Symbol - completing the set and winning the Battle Frontier. After his victory, Scott offered Ash the position of Frontier Brain when one of them retired but he declined, opting instead to continue his journey. Before saying goodbye to May, Ash competed against her in the Terratta Pokemon Contest, their match ending in a tie. There was only one ribbon and they couldn't decide who to give it to. Ash had his Sceptile use Leaf Blade to cut the ribbon in half, choosing to split it with May before they all parted ways. Returning home, Ash met up with Gary again and saw the latter's new Electivire. Gary informed Ash about the region of Sinnoh, to which he immediately decided to travel next on his journey.
Diamond and Pearl Series
Pokémon: Diamond and Pearl
Departing for Sinnoh, Ash once again left his previous captures at Professor Oak's laboratory, with the exception of his Aipom who'd snuck along. After arriving in Sinnoh by boat and reuniting with Brock, he gained yet another new traveling companion in Dawn, a confident girl interested in following in her mother's footsteps as a Pokemon Coordinator. After receiving new clothes from his mother in the mail, Ash gained a new rival in a Trainer named Paul. Later in the season, Ash misses meeting Team Galactic due to moving on with his journey too soon. He won his first two Sinnoh Gym Badges: a Coal Badge from Roark and a Forest Badge from Gardenia. Ash encountered Pokemon Hunter J, who temporarily kidnapped Pikachu by turning it into stone. Ash's first Sinnoh capture was a Starly which evolved into Staravia, and a Turtwig. His final Sinnoh acquisition came when he adopted Paul's Chimchar by the end of the season.
Pokémon: DP Battle Dimension
In this season, Ash continued battling and earning badges while Dawn continued to earn contest ribbons. They also encountered Team Galactic and tried to stop them from stealing the Adamant Orb. During this time, Ash earns his fifth Gym Badge. For most of the season, Ash had to wait for Gym Leader Fantina to return to her Gym in order to challenge her. Ash reunited with May during the Wallace Cup and took part as a coordinator once again (per Wallace's request). Late one night with Pikachu, he saw the spirit of Azelf rise out of the lake the contest was being held at. He tied with Maylene but earned a Cobble Badge from her and defeated both Crasher Wake and Fantina for the Fen and Relic Badges. He also acquired a new rival in Barry, a somewhat clumsy boy who insists on fining people. Ash acquired a few more Pokemon during this season; at the suggestion of Zoey, he traded his Aipom for Dawn's Buizel, the only trade so far he hasn't reversed; his Turtwig evolved into Grotle; and he caught a Gligar which became a Gliscor.
Pokémon: DP Galactic Battles
Continuing his journey in Sinnoh, Ash managed to beat Byron, winning the Mine Badge and Candice, winning the Icicle Badge. Along the trip to Sunyshore City, Ash and his friends encounter International Policeman Looker and were recruited to help stop the plans of Team Galactic as the three of them were chosen to share a bond with the three Lake Spirit Pokémon, during which Brock managed to find Uxie. Managing to find Team Galactic in the middle of creating a new universe with the captive Lake Trio controlling Palkia and Dialga, Ash, Dawn and Brock freed the trio and Team Galactic was arrested while their leader vanished into the collapsing new world, effectively disbanding Team Galactic. At the end of the season, Ash caught himself a Gible which was learning Draco Meteor.
Pokémon: DP Sinnoh League Victors
After the Team Galactic incident, Ash entered the Sinnoh League after beating Volkner and earning the Beacon Badge. He also reunited with Jasmine from the Olivine Gym before heading to Lily-of-the-Valley. Taking a different approach in this League than he did in Hoenn, Ash combined his previous captures with his current Pokemon to form well-balanced teams of new and old. The Sinnoh League was one of the hardest and most intense Leagues he ever competed in, as he had rivals Paul and Barry to compete with, and a mysterious trainer who joined with the Legendary PokémonDarkrai. He battled against most of his rivals save for Barry, who battled Paul and lost, so Ash's next match was against Paul.
The battle was intense as Paul showed Pokémon that he didn't normally use while Ash had reassembled his team of six from their earlier battle at Lake Valor. The fight came down to Paul's Electivire and Ash's Infernape. Despite taking heavy damage, Infernape won the match for Ash with its ability, Blaze. After defeating Paul, Ash faced an opponent other Trainers in the League dreaded to face as he was hard to defeat: the Trainer with the Darkrai: Tobias. After losing a couple of Pokemon to it, Ash was able to defeat Tobias' Darkrai with Sceptile and even knocked out Tobias' Latios with Pikachu. However, as the rest of Ash's Pokémon had fainted, he was eliminated. To this day, the Sinnoh League remains Ash's most impressive performance in a Pokemon League Tournament: he reached the Top 4 - the farthest he'd ever gotten in any Pokemon League - and was the only one of Tobias' opponents to defeat two of his Pokemon, let alone his Darkrai. After the Sinnoh League, Ash bade farewell to Dawn as she wished to continue entering contests, and also parted ways with Brock, his oldest friend and longest-running traveling companion for the final time, as Brock now wished to become a Pokémon Doctor.
Black and White Series
Pokémon: Black & White
At home in Pallet Town, Ash received new clothes and was invited along with his mother by Professor Oak to take a trip to the far away Unova region for a scientific expedition. Upon arrival, a more formidable Team Rocket - no longer fooling around and acting in a more serious capacity - once again tried to capture Pikachu. This was prevented by the timely intervention of Zekrom, one of Unova's two Legendary Pokemon. Zekrom caused a storm that scared away Team Rocket and temporarily knocked Pikachu out. Arriving at Professor Juniper's lab, Ash encountered a new rival named Trip, an insolent boy with an intolerant attitude towards Trainers from Kanto. Ash battled Trip, but lost as Pikachu's Electric attacks had been temporarily disabled from the encounter with Zekrom. Ash later decided to go out on a new quest to win the Unova League. After leaving on his new journey, Ash gained new traveling companions in Iris, an up-and-coming Dragon Master with keen eyesight, and Cilan, one of the three optional Gym Leaders of the Striaton City Gym who utilized Grass-Type Pokemon and also a Pokemon Connoisseur. Ash continued his inadvertent tradition of catching all three Starter Pokemon of a region, something not done since Johto: He adopted an Oshawott that had snuck away from Professor Juniper's lab and an abandoned Tepig whose Trainer no longer wanted it. Last but not least, Ash caught a very strong Snivy which acts like the mother of his team. Ash won the Trio Badge, Basic Badge and Insect Badge. As the season continued, he acquired a mysterious egg which later hatched into his Scraggy.
Pokémon: BW Rival Destinies
Continuing on his journey through Unova with Iris and Cilan, after they stopped Team Rocket from stealing Pokémon from the Nimbasa Pokémon Center, Ash and co. met up with Bianca and encountered both the Gym Leader Elesa and Bianca's father. After he allowed both his daughter and Ash to continue their respective journeys, Ash battled Elesa and won the Bolt Badge. Then he had the honor of meeting Alder, the Unova League Champion. He also saved Unova from being torn apart by Tornadus and Thundurus by summoning Landorus. Following this, Ash had a Gym Battle with Clay after getting him some Revival Herbs. During the battle Ash's Roggenrola evolved into a Boldore; using its ability, Sturdy, Ash defeated Clay, earning him the Quake Badge. After that he helped Bianca with her newly evolved Escavailer and met Cedric Juniper. He managed to catch the Krokorok that followed him, adding it to his team. Finally, he had a Gym battle with Skyla, duuring which his Tranquill evolved into Unfezant and managed to beat her, winning the Jet Badge. He participated in a race to the top of Celestial Tower and came in a close second losing to Stephan, as well as the Donamite tournament and ranked Semi-finalist. He also confronted Tepig's original trainer, Shamus, during which Tepig evolved into Pignite. He also had to endure a harsh training session from Brycen, which paid off as he won the Freeze Badge. His plans to go to Opelucid City were on hold as he found out the Gym was closed and had to go to Virbank City instead, where he battled Roxie and won his final badge, the Toxic Badge. He also met and befriended a Meloetta and reunited with his old friend Dawn from his time in Sinnoh and stopped Team Rocket's latest plot involving Meloetta. Along the way he met Cameron who faced off against Marlon, the Humilau CityGym Leader.
Pokémon: BW Adventures in Unova
Ash finally arrived at and competed in the Unova League, placing in the Top 8 as he'd done before. He made a new friend, N and learned about Team Plasma and another Legendary Pokémon, Reshiram. With N's help, Ash was able to stop Team Plasma. With his adventures in Unova behind him, it was time for him to head home again: fortunately for Ash, Professor Juniper scored him boarding tickets to the Queen Decolore which traversed through the Decolore Islands. Along the way he met Alexa, a reporter from the Kalos region and briefly reunited with Clair from the Blackthorn Gym to help find a Shiny Druddigon. After arriving in Vermillion City, he parted ways with Iris and Cilan as the two were headed to Johto, and returned home to Pallet Town once again with Alexa.

He gained new traveling companions in the siblings Clemont and Bonnie and later reunited with his childhood friend Serena, who still remembered Ash rescuing her a long time ago and would travel with him as well. Despite being childhood friends with Serena, he had no memory of their relationship until Serena showed him the handkerchief he used to mend her knee when they were little kids in the episode, Giving Chase at the Rhyhorn Race!. Ash also caught three new Pokemon: his first Kalos capture was a Froakie followed by a Fletchling then a Hawlucha. Within the first five episodes of the season, Ash faced Alexa's sister Viola, the Gym Leader of Santalune City who specialized in Bug-type Pokemon. During their battle, Ash faced difficulty against Viola's Surskit, who gained an advantage over Pikachu by freezing the arena, turning it into an ice field. Ash decided that what needed improving was his Pokemon's balance, and with Alexa's help, engaged in special training designed to combat this flaw. Clemont also tried to help using one of his latest devices, but the machine backfired and exploded. In a rematch, Ash ultimately defeated Viola and claimed the Bug Badge, his first badge from a Kalos Gym. Much later, Ash battled against the Cyllage City Gym Leader Grant and his Rock-Type Pokemon. Having seen Grant defeat Viola at the Battle Chateau, Ash sought a way to defeat Grant's Rock Tomb. When he faced Grant, this ended up becoming Rock Tomb Climb, the use of which earned Ash his second Kalos Badge, the Cliff Badge. Some time later, Ash battle Moria, a Sky Trainer who specializes Sky Battles, and her Talonflame. During the battle his Fletchling evolved into a Fletchinder and won. At the Pokémon Summer Camp, Ash and his friends met Shauna, Trevor, and Tierno. He later had a first-touch-battle against Tierno's Squirtle with Froakie and lost. After spending a good time at the Pokémon Summer Camp, Ash went to Shalour City and battled Korrina, a Gym Leader who previously traveled with Ash and his friends in order to help her understand Mega Evolution with her Lucario. Despite a failed attempt of using Tierno's dancing strategy, Ash managed to win his third Kalos Badge, the Rumble Badge.
Ash was given Pikachu by Professor Oak as the original Kanto starter Pokemon had been taken. Originally, Pikachu would not listen to Ash and constantly shocked him. However, after accidentally angering a flock of Spearow, Pikachu had a change of heart when it saw Ash defend him. Since then, Pikachu has assisted and been very successful in many of Ash's wins and over time has adopted Ash's mannerisms.

Froakie knows Water Pulse, Bubble, Pound, Double Team, and Cut.
Fletchling first appeared where it swooped down to take a berry that Bonnie gave to a Dedenne.

Ash threw a Poké Ball at it but the capture was unsuccessful. Froakie continued the battle with Fletchling and landed a hit with Water Pulse. Ash threw another Poké Ball at Fletchling and managed to catch it this time. It later evolved into Fletchinder during a sky battle against Moria's Talonflame.

Ash's Staraptor evolved from Staravia during a PokéRinger contest against Paul's Honchkrow. As it has evolved, it is likely to become one of the powerhouses of Ash's team and will still likely be used for long-distance searching. With it's bigger size and strength, as soon as it evolved, it learned the move Close Combat, which will be helpful for many close flying battles.
Torterra is the Grass type Pokémon of Ash's Team. After being used in a gym battle against Volkner, which got postponed, Ash's Grotle evolved during a battle with Team Rocket.

Buizel will likely be called upon often for battles.
During its Gligar stage, Gliscor was a fairly weak Pokémon, not knowing many attacks and thus not being very strong, all due to its age.

Ash's Japanese name, Satoshi, comes from Satoshi Tajiri, the creator of Pokémon. Ash may be a shortening of Satoshi and his last name, Ketchum, may have come from the phrase "Gotta catch 'em all".
Ash has had 49 Pokémon including different evolutionary forms (78 if all Tauros are included).
Ash has caught at least one of the Starter Pokémon in every region, and has caught the main bird Pokémon that appears in that region's Pokédex.
He caught Pidgeotto in Kanto that later evolved into Pidgeot (Ash also almost captured a Spearow and later that same Pokemon evolved into Fearow) which he soon released to protect and lead a flock Pidgey and Pidgeotto.
It is Interesting to note that Ash must have accidentally evolved the Spearow into a Fearow a few episodes after its first appearance.
He captured Taillow that later evolved into Swellow in Hoenn.
He captured Starly that later evolved into Staravia then Staraptor in Sinnoh.
He caught a female Pidove that evolved into Tranquill then Unfezant in Unova.

Ash is the only known trainer to have ever defeated Tobias' Darkrai.
In the Kanto region, Ash often turned his cap backwards when preparing for a battle or to capture a Pokemon. This habit wore off as time went on. However he was shown turning his cap backwards when he was battling Tobias, presumably because Tobias was arguably the strongest trainer he'd ever faced, being the only one who was capable of beating all six of his Pokemon using only two of his own. Although in the Best Wishes series, Ash is seen turning his cap backwards more often. He recently turned his hat around in A Battle of Aerial Mobility! when he used Froakie to help defeat and capture Fletching.
Ash turned 10 at the start of the series and was canonically so from seasons 1-3, though it is unknown if he actually aged. According to the narration of In the Shadow of Zekrom!, he's still 10, although this narration is probably inaccurate, or maybe the directors have confirmed that Ash is still 10.
Ash has seen every legendary Pokémon from Kanto to Unova.
In Tekken 6, there is a female character named Eleonore "Leo" Kliesen, who can be customized to look like Ash Ketchum. Coincidentally, both characters were voiced by Veronica Taylor and sounded very similar.
Almost every character in the Pokémon anime are featured in the games, such as Misty (who even appeared as a trophie in Super Smash Bros. Melee), Brock (who appeared in Pokémon Red/Blue version), and Lyra (from Diamond & Pearl), as a Trainer♀ in Pokemon HeartGold/SoulSilver version and Gary, who appeared as main rival in Pokémon Red/Blue version default named as Blue.
