List Of Pokémon Characters

This is a list of characters in the ''Pokémon'' franchise, including the games. Characters may appear in multiple continuities, sometimes in the same basic role (e.g. Giovanni) and sometimes in very different roles (e.g. Brock).

All references to the "video games" collectively refer to ''Pokémon Red'', ''Green'', ''Blue'', ''Yellow'', ''Gold'', ''Silver'', ''Crystal'', ''Ruby'', ''Sapphire'', ''Colosseum'', ''FireRed'', ''LeafGreen'', ''Emerald'', ''XD: Gale of Darkness'', ''Diamond'', ''Pearl'', ''Platinum'', ''HeartGold'', ''SoulSilver'', ''Black'', ''White'', ''Black 2'', ''White 2'', ''X'', ''Y'', ''Omega Ruby'', ''Alpha Sapphire'', ''Sun'', ''Moon'', ''Ultra Sun'', ''Ultra Moon'', ''Let's Go, Pikachu!'', ''Let's Go, Eevee!'', ''Sword'', ''Shield'', ''Brilliant Diamond'', ''Shining Pearl'', ''Legends: Arceus'', ''Scarlet'', and ''Violet''.

Names in bold are the names from the English language versions of the video games or anime. Names within parentheses in plain text are the anglicized form of the characters' original Japanese language name if different from the English language version. ''Italicized'' names are the romanized version of the Japanese language name if different from the anglicized version.

Protagonists

The protagonist of the video games can be renamed by the player, but each has an array of default names. As the anime and the manga are, to differing degrees, based on the games, other Pokémon protagonists (or supporting characters) are often named after and share many characteristics with the game protagonists.

Main series

* : The protagonist of ''Pokémon Red'', ''Green'', ''Blue'' and ''Yellow'' and the male protagonist of ''Pokémon FireRed'' and ''LeafGreen''.

In ''Pokémon Adventures'', he is the champion of Kanto, and later, in the ''Yellow'' chapter, defeated by Bruno of the Elite Four on Mt. Moon and frozen by Lorelei, later freed by Giovanni, and given 3 infinite-use evolution stones for his genetically modified Eevee. He then beat Bruno in a rematch.

Rivals

Each game will have one or more rivals. Some rivals can be renamed, while some rivals cannot. They roughly correspond to several other characters in the anime and the manga. The rivals will usually pick a starter Pokémon which has a type advantage over the player's own. In the more recent games, the rival will pick the starter with a type disadvantage against the player, most likely to make the rival battles easier.

Main series

* : The rival of ''Pokémon Red'', ''Green'', ''Blue'' and ''Yellow'' and ''Pokémon FireRed'' and ''LeafGreen''. He is pushy and competitive, but is generally a good Pokémon Trainer. He is the grandson of Professor Oak and the player's childhood friend. After that he became the Champion of the Kanto region, waiting for the player to challenge him. Blue is the basis for Gary Oak in the anime. IGN listed Blue as the 98th best villain in video games, though they stressed that it was difficult to view him as a villain. However, they did say that he was kind of a "douche", citing his attempt to prevent the player character from getting a map. Three years later in ''Pokémon Gold'', ''Silver'' and ''Crystal'' and their remakes, ''Pokémon HeartGold'' and ''SoulSilver'', he becomes a Gym Leader for Viridian City. He acts as Kanto's Champion in ''Pokémon Black 2'' and ''White 2'''s Pokémon World Tournament, and alongside Red in ''Pokémon Sun'' and ''Moon'' and their ''Ultra'' versions.
* : The rival of ''Pokémon Gold'', ''Silver'' and '' ''Crystal'''' and ''Pokémon HeartGold'' and ''SoulSilver''. This character steals his first Pokémon from Professor Elm and tends to see Pokémon as tools, to use and discard. Unlike the first rival, his view on Pokémon makes him a mediocre trainer, though the sage in the Sprout Tower recognizes that he is talented and has great potential, as does Lance, the Johto Champion. He eventually realizes his wrongdoings and changes his ways by treating his Pokémon and even the player with respect. This comes to a head in ''Pokémon Masters EX'', in which he is identified by Ho-Oh as being pure of heart and becomes his Pokémon. He is finally revealed to be the son of Team Rocket Boss Giovanni.
* : The rival in ''Pokémon Ruby'', ''Sapphire'' and ''Emerald'' and ''Pokémon Omega Ruby'' and ''Alpha Sapphire''. In the beginning, he is a sickly young boy who needs help in catching a Pokémon. When he goes to the player's father for advice, Norman directs the player to help him catch a Pokémon. Using Norman's Zigzagoon, the player helps Wally catch a Ralts. The next time he battles the protagonist, he seems healthier and is in tune with his Pokémon. He battles the player for the last official time in Victory Road and waits there, always ready for another battle.
* : The rival of ''Pokémon Diamond'', ''Pearl'' and ''Platinum''. He is often impatient and is determined to be the best Trainer of all time. He is best friends with the player and his father, Palmer, owns the Battle Tower in Sinnoh. Sometimes he will aid the player. He tends to accidentally crash into people quite often as he runs about, and often tries to fine people for being too slow. This is due to him apparently wanting to save up for a Battle Tower to compete with his father's.
* : One of the rivals of ''Pokémon Black'' and ''White''. Cheren is intelligent and trustworthy; he often gives the player character advice and battles the player to test his skills. Like the player, he aims to become the Champion. He is one of the player's childhood friends. Two years later, in ''Black 2'' and ''White 2'', he becomes Aspertia City's Gym Leader. If the player used the Memory Link function in ''Black 2'' and ''White 2'', he challenges the player using his final team from ''Black'' and ''White''. His name is from the Bulgarian word for black: (''cheren'').
* : One of the rivals of ''Pokémon Black'' and ''White''. Bianca is spontaneous and sometimes unreliable, but she develops over the course of the journey. She also has a strong side, which she shows when she goes on a Pokémon journey against her father's wishes. Her father wants her to stay back at home, believing it unsafe out in the world, until he is eventually convinced to keep Bianca on her journey by Elesa. She is one of the player's childhood friends. Two years later in the events of ''Black 2'' and ''White 2'', Bianca becomes an assistant to Professor Juniper and gives the player their starter Pokémon. If the player used the Memory Link function in ''Black 2'' and ''White 2'', she challenges the player using her final team from ''Black'' and ''White''. Bianca's name is from the Italian word for white, while her Japanese name "Bel" has the same meaning from Russian: (''bel'').''CoroCoro Comic'' July 15, 2010
* : The rival of ''Pokémon Black 2'' and ''White 2''. He is from Aspertia City and one of the player's childhood friends. Like the player characters and is also seeking to become a Pokémon Master. Throughout the game, the player helps Hugh retrieve his sister's Purrloin which was stolen by Team Plasma years ago.
* : One of the rivals and friends of ''Pokémon X'' and ''Y''. She is energetic and curious, but still does not know what she wants to gain from her experiences. She gives the player character a nickname at the outset of their journey. Like the other rivals, she is available as a Multi Battle partner at the Battle Maison.
* : One of the rivals and friends of ''Pokémon X'' and ''Y''. He is more interested in finding new Pokémon to make a perfect Pokémon Dance Team.
* : One of the rivals and friends of ''Pokémon X'' and ''Y''. He is studious and wishes to fill up all three parts of the Kalos Region's Pokédex.
* : One of the rivals of ''Pokémon Sun'' and ''Moon'' and ''Pokémon Ultra Sun'' and ''Ultra Moon''. Compared to previous rivals, he is more friendly, and loves malasadas. He is Melemele Kahuna Hala's grandson. In Ultra Sun and Ultra Moon, he challenges the player as their final battle before becoming Champion.
* : One of the rivals of ''Pokémon Sun'' and ''Moon'' and ''Pokémon Ultra Sun'' and ''Ultra Moon''. This young man lends his strength to Team Skull as an enforcer. He places a high value on being strong in Pokémon battles. His partner Pokémon is the mysterious Type: Null, which later becomes Silvally. He is Lusamine's son and Lillie's brother.
* : The rival of ''Pokémon: Let's Go, Pikachu!'' and ''Let's Go, Eevee!''. He is considered far too nice by many. He eventually becomes Champion of Kanto, and acts in a similar vein to Blue.
* : One of the rivals in ''Pokémon Sword'' and ''Shield''. He is the younger brother of Leon, the Champion of Galar. He idolizes his brother and only aspired to become Champion because of said reason. He continues to grow frustrated by constant losses to the player, until he eventually changes paths and sets out on becoming a Pokemon Professor.
* : One of the rivals in ''Pokémon Sword'' and ''Shield''. He is an arrogant trainer whose Pokémon journey is sponsored by Chairman Rose. After being disqualified from the Gym Challenge, Opal takes him under her wing and strongarms him into becoming her successor as the Ballonlea Gym Leader (Fairy Boot Camp). He initially specializes in Psychic-type Pokémon, but switches to Fairy types after becoming a Gym Leader (though a majority of his team still has the Psychic type).
* : One of the rivals in ''Pokémon Sword'' and ''Shield''. She is the younger sister of Piers, who is the Gym Leader of Spikemuth. Team Yell, a hooligan-esque group composed of Gym Trainers from Spikemuth, are her troublesome fans. After the game's conclusion, she succeeds Piers as the Spikemuth Gym Leader. She specializes in Dark-type Pokémon (with a little bit of diversity, as not all Pokémon on her team have the Dark type). In a secret post game cutscene in the Budew Drop Inn, she is shown to be incapable of smiling.
* Klara (クララ, ''Kurara''): The rival in the Isle of Armor story in ''Sword''. She specializes in Poison-type Pokémon. Her signature Pokémon is a Galarian Slowbro. She was an underground "idol" and aspires to become a Poison type gym leader to acquire fans. She cares a lot for her appearance, as she is shown to photoshop her league card (proven by looking at the weirdly shaped Slowbro behind her).
* Avery (セイボリー, ''Savory''): The rival in the Isle of Armor story in ''Shield''. He specializes in Psychic-type Pokémon. His signature Pokémon is a Galarian Slowking. He came from a family of psychics, but was shunned for not being able to teleport (as shown he always screams "Avery, Teleport!" while he runs away) nor read minds. He aspires to prove his family wrong and become a Psychic type gym leader.
* : The rival in ''Pokémon Scarlet'' and ''Violet''.

Spin-offs

* : The rival of ''Pokémon Trading Card Game'' and '' Pokémon Card GB2: Here Comes Great Team Rocket!''.

* : The initial rival of ''Pokémon Masters EX'', eventually supplanted in this role by Lear.

Professors

The Pokémon Professors give new Pokémon trainers a starting Pokémon appropriate to their region and entrust them with a task (be it completing a Pokédex, delivering an object or otherwise offering encouragement). They are also leading researchers of Pokémon-related topics and mentor Pokémon trainers in a general way.

Main series

* Professor Samuel Oak (): A Pokémon researcher and the grandfather of Blue in ''Pokémon Red'', ''Blue'', ''Green'', ''Yellow'', ''FireRed'' and ''LeafGreen'' and ''Let's Go, Pikachu!'' and ''Let's Go, Eevee!''. He is often considered the leading Pokémon expert, often giving lectures to Pokémon academies and hosting a radio show in Goldenrod City and specializes in Pokémon behavioral science. Alongside his research, he is also authorized by the Pokémon League to give new Pokémon trainers one of the three Kanto starter Pokémon: Bulbasaur, Squirtle and Charmander. In the anime, he gives Ash his Pikachu after Ash arrives too late to receive one of the usual three starter Pokémon. In '' Pokémon Yellow: Special Pikachu Edition'', he simply gives the player a Pikachu after the rival takes the Eevee that Oak intended to give the player. He is a master Pokémon poet. All Pokémon he "baby-sits" are loyal to him and he had a Charmeleon as a young boy. In ''Pokémon 4Ever'', it is shown that he traveled forward in time to the future when he was a boy and Ash became friends with him. When Ash tells Professor Oak about him, he replies that he is sure that "Sammy" will always be his friend, even though Misty later realizes that Ash never told him his name; the current Professor Oak is later seen looking through a book of old drawings he made as a kid (the predecessor to the Pokédex, which he invented with the other professors). He is colleagues with many other professors, including Rowan and Willow.
* Professor Elm (): An absent-minded Pokémon researcher and former student of Professor Oak. In ''Pokémon Gold'', ''Silver'' and ''Crystal'', he is authorized by the Pokémon League to give new Pokémon trainers one of the three Johto starter Pokémon: Chikorita, Cyndaquil and Totodile. He is also credited as discovering that Pikachu is an evolved Pokémon. In the ''Pokémon'' anime, Jessie, James and Meowth temporarily steal a Totodile from him (in reality he tells them to take it, thinking they are Nurse Joy). His 'absent minded professor' stereotype is even more pronounced in the games as he often forgets to visit his family and his wife worries that he may not remember to eat. He specializes in research regarding Pokémon breeding and is credited with the discovery of Pokémon eggs, even gifting the player a Togepi egg for research via his aide in the games.
* Professor Birch (): A Pokémon researcher, known for his fieldwork and research on Pokémon habitual distribution. In ''Pokémon Ruby'', ''Sapphire'', ''Emerald'', ''Omega Ruby'' and ''Alpha Sapphire'', he is authorized by the Pokémon League to give new Pokémon trainers one of the three Hoenn starter Pokémon: Treecko, Torchic and Mudkip. He is the father of the rival character. In the anime, he gives May her Torchic. In the manga, he is the father of Sapphire. At the beginning of the game, he is attacked by a Poochyena ( Ruby, Sapphire, Omega Ruby, Alpha Sapphire) or Zigzagoon (Emerald), and drops his bag, resulting in the player having to use one of his Pokemon, the Hoenn starter Pokemon, to save him from his attacker. He later gives the player the starter they chose and a Pokedex.
* Professor Rowan (): The Pokémon Professor in the ''Pokémon Diamond'' and ''Pearl'' games, having returned to Sinnoh after four years of traveling abroad. A senior researcher to and old friend of Professor Oak, Professor Rowan is known for his research on Pokémon evolution. He is authorized to give trainers one of three Sinnoh starter Pokémon, Turtwig, Chimchar or Piplup. In the anime, he gives Dawn her Piplup. He has an assistant, either Lucas or Dawn, depending on which player character was not chosen by the player.
* Professor Aurea Juniper (): The Pokémon Professor in the ''Pokémon Black'' and ''White'' games, the first female professor to appear in the video game series. Professor Juniper specializes in research involving the origins of Pokémon. She is authorized by the Pokémon League to give new trainers one of three Unova starter Pokémon, Snivy, Tepig and Oshawott. In the game, she leaves a present at the player's house containing starter Pokémon for the player and the player's rivals, Bianca and Cheren. In the anime, she gives Trip a Snivy and allows Ash to keep an Oshawott that escapes from her lab. Her father, Cedric Juniper, was also a Pokémon Professor and has since retired; in the games, he upgrades the player's Pokédex to the National mode after the player defeats N and Ghetsis.
* Fennel (): Fennel is a Pokémon professor in the Unova Region who studies Pokémon trainers as well as the dreams of Pokémon. The player encounters her when Team Plasma abducts a Munna from her research facility to use its Dream Mist powers to reach its goals. She gives players the C-Gear item as well as access to the Pokémon Dream World online system.
* Professor Augustine Sycamore (): A professor who debuts in the Pokémon games ''Pokémon X'' and ''Y''. He battles the player from time to time. Unlike previous professors who gave out the regions' new starter Pokémon, Kalos's starter Pokémon Chespin, Fennekin and Froakie are given to you by one of the player character's friends. Instead, Professor Sycamore gives the player a choice amongst Kanto's starter Pokémon: Bulbasaur, Charmander and Squirtle.
* : The Pokémon Professor in ''Pokémon Sun'' and ''Moon''. Professor Kukui studies Pokémon moves. He takes Lillie under his wing as his assistant and is married to Professor Burnett. He has a secondary double life as The Masked Royal and is one of the strongest opponents in the Battle Royal. He is good friends with Molayne, who keeps his double life a secret. He takes one of the Alolan starter Pokemon under his wing, whichever was not chosen by Hau or the player, and later uses it in battle in its final form. He acts as the final opponent before becoming Champion in Pokemon Sun and Moon.
* : The Pokémon Professor in ''Pokémon Sword'' and ''Shield''. She studies the Dynamax phenomenon. Sonia is her granddaughter. She is responsible for the player and Hop's Dynamax Bands, as well as encouraging their endorsement by Leon. She later steps down as Professor after Chairman Rose nearly causes the next Darkest Day.
* : Sonia becomes the Galar professor after announcing her discovery of the legend of the darkest day in front of the Hammerlocke gym in ''Pokémon Sword'' and ''Shield''. She appears throughout the story prior to this, often assisting the player and Hop. She is a close friend of Nessa and was childhood rivals with Leon. She publishes a book on her Dynamax research, which causes Sordward and Shielbert to start the events of the postgame story. In the Crown Tundra, she is researching the Swords of Justice, Cobalion, Terrakion, and Virizion in Freezington. She also owns a Yamper, who helps her in her research.
*Professor Laventon: The Pokémon Professor of the Hisui region. He specializes in the ecology of Pokémon.
* and : The Pokémon Professors in ''Scarlet'' and ''Violet'' respectively, that are actually robotic duplicates of the originals. They are the first professors not to be named after trees, with Sada's name coming from the Spanish word for past, "pasado", and Turo's name coming from "futuro", the Spanish word for future. They study the possible relationship between past/future versions of modern-day Pokémon, otherwise known as Paradox Pokémon. They were also indrectly responsible for the appearance of the Terastal phenomenon originating from Area Zero, which is abundant with Tera Crystals. The robotic counterparts realised that what their original selves were doing (bringing Paradox Pokémon from each respective timeline into Paldea to create a paradise without any regard of the damage they would cause to Paldea) was wrong, but in the endgame, under the influence of an emergency protocol by their original selves' time machine (the ''real'' villain of ''Scarlet'' and ''Violet''), they end up defending the machine against their will with a full team of Paradox Pokémon from the respective timelines, including a hostile individual of Koraidon/Miraidon that killed their original selves. Afterwards, they then travel to each timeline knowing it was the only way to stop the time machine from bringing any more Paradox Pokémon to the present. Sada's fate remains unknown in Pokémon Violet while Turo's fate remains unknown in Pokémon Scarlet.

Pokémon League

Gym Leaders

are trainers who lead Pokémon Gyms and offer Gym badges to Pokémon trainers who can defeat them. Usually, this challenge takes the form of a Pokémon battle, but, occasionally, the challenges are a trial of skill or endurance or the badges are given in return for extraordinary services rendered. Each main region has at least eight Gym Leaders. Any trainer who earns eight Gym Badges is eligible to go on to face the Elite Four or participate in the Pokémon League Championships.

* Whitney (): Goldenrod City Gym Leader and an expert on Normal-type Pokémon. She is known to throw tantrums when she loses, but is otherwise a cheerful Gym Leader and a good sport once she calms down.

She plays a larger role in ''HeartGold'' and ''SoulSilver'', including meeting the player again at the Pokéathlon Dome, and being an active participant.

His ace is Piloswine, and sometimes its evolved form Mamoswine.
* Clair (): Blackthorn City Gym Leader and an expert on Dragon-type Pokémon. Clair is the younger cousin of Elite Four member and Champion, Lance.

Wattson helped develop Sea environment and New Mauville, and ended up being involved in their closure due to issues with Pokemon and the environment. Wattson also developed the conversion plans for Mauville City, which were shown in ''Pokémon Omega Ruby'' and ''Alpha Sapphire'', making the city fully indoors and more high tech. His ace is typically Manectric, but in ''Pokémon Ruby'' and ''Sapphire'' and their remakes, Magneton acts as his ace.
* Flannery (): Lavaridge Town Gym Leader and an expert on Fire-type Pokémon.

Battle facility leaders

Frontier Brains

The are a group of powerful Pokémon trainers from the Battle Frontier that appears in ''Pokémon Emerald'', ''Pokémon Platinum'' and ''Pokémon HeartGold'' and ''SoulSilver''. Each Brain resides at a Frontier facility and has his or her own title. After defeating a Frontier Brain, the trainer will receive a Silver Symbol (1st time) or Gold Symbol (2nd time). In Platinum, the trainer will receive a Silver Medal (1st time) or Colored Medal (2nd time).

In the anime, Ash Ketchum travels the land of Kanto after his journey in Hoenn, defeating the Frontier Brains. Instead of being on the Battle Frontier island, the facilities are in cities in Kanto.

In the ''Pokémon Adventures'' manga, a mysterious boy called Emerald, who has a connection with Latias and Latios, comes to the Battle Frontier island to defeat the Frontier Brains. Todd, a character from the anime and the Pokémon Snap games, watches Emerald go through the frontier. Similarly, Platinum Berlitz challenges the Frontier Brains of Sinnoh alongside Looker in order to learn more about the Distortion World in a later chapter of the manga.

Hoenn Frontier Brain

* Salon Maiden Anabel () resides in the Battle Tower. She uses a variety of Pokémon. In the manga, she is the leader of the Frontier Brains and her Battle Tower is considered "special". In the anime, Ash challenges her before Pyramid King Brandon. After Ash and Anabel's battle, it is hinted that Anabel had fallen in love with Ash. She gives the Ability Symbol. She appears in ''Pokémon Sun'' and ''Moon'', working alongside Looker in investigating the Ultra Beasts, although with almost no memory of her time in the Battle Frontier.
* Dome Ace Tucker () resides in the Battle Dome. Tucker prefaces battles with narcissistic comments and enjoys the sound of a crowd chanting his name. He uses Pokémon that are one of a kind, for example, the final evolutions of starter Pokémon. He turns over the Tactics Symbol.
* Palace Maven Spenser () resides in the Battle Palace. In Pokémon Adventures, he once touched the Blue Orb, which controls Kyogre, so he can tell who also has touched it. When battling him, Emerald is not allowed to issue commands to his Pokémon, who must battle based on their instincts and sense of strategy; challenges against Spenser require the trainer to have faith in the Pokémon he has chosen. He hands out the Spirit Symbol.
* Arena Tycoon Greta () resides in the Battle Arena. A blunt girl who likes to face powerful trainers; she hands out the Guts Symbol to those who defeat her.
* Factory Head Noland () resides in the Battle Factory in Hoenn. As the Factory Head, he is able to view the Battle Swap data of any trainer and advocates gaining experience rather than relying solely on acquired knowledge. Noland battles with a randomly selected team each time he is challenged, which can include any Pokémon except those that are not admissible in the Battle Frontier. He hands out the Knowledge Symbol. In the ''Pokémon Adventures'' manga, he is the first to battle with Emerald and is in charge of the raising and caring for all the rental Pokémon.
* Pike Queen Lucy () resides in the Battle Pike. Lucy prefers to use serpent-like Pokémon. She is very tall, quiet and pale, with knee length black hair and sharp looking eyes. Never saying much, defeated or otherwise, she does state that it took a great deal of work to get to her level of skill. Instead of a series of battles like the other facilities, Lucy's Pike consists of rooms that randomly have either a double battle, a wild Pokémon, a healing station, a trainer battle or a random conversation. She hands over the Luck Symbol. In the Pokémon Adventures manga, she is the second to battle with Emerald.
* Pyramid King Brandon () resides in the Battle Pyramid. A man who appreciates the grand life of an explorer, he uses trios of Legendary Pokémon. In Pokémon Adventures, he remarks that he favors one-hit knockout moves and had captured Regirock, Regice and Registeel after the trio disappeared following the battle in Hoenn to stop Groudon and Kyogre. In the anime, Ash notably faces Brandon several times before finally defeating him as the final Frontier Brain. Brandon hands out the Bravery Symbol.

Sinnoh and Johto Frontier Brain

* Tower Tycoon Palmer () resides in the Battle Tower in Sinnoh and later, in Johto. He was first introduced in ''Pokémon Diamond'' and ''Pearl'' as the leader of the Battle Tower, which was later incorporated into ''Pokémon Platinum''s Battle Frontier. He gives away the Silver Tower Print to trainers that defeat him once and the Gold Tower Print to trainers that beat him twice.
* Factory Head Thorton () resides in the Battle Factory in Sinnoh and later, in Johto. Like Factory Head Noland, Thorton's team is randomly selected each time he is challenged and can include any Pokémon except those inadmissible to the Battle Frontier. He gives away the Silver Factory Print to trainers that defeat him once and the Gold Factory Print to trainers that defeat him twice.
* Hall Matron Argenta () resides in the Battle Hall in Sinnoh and later, in Johto. Argenta uses a strange strategy to test trainers and forces them to choose one Pokémon to battle 10 Pokémon of each type during their challenge. She gives away the Silver Hall Print to trainers that defeat her once and the Gold Hall Print to trainers that beat her twice.
* Arcade Star Dahlia () resides in the Battle Arcade in Sinnoh and later, in Johto. Her challenge consists in using a roulette simulator that randomly chooses a special condition for the upcoming battle. She gives away the Silver Arcade Print to trainers that defeat her once and the Gold Arcade Print to trainers that beat her twice. She is also known to be a great dancer according to some trainers at her facility.
* Castle Valet Darach () and Lady Caitlin () reside in the Battle Castle in Sinnoh and later, in Johto. Darach is the butler of Caitlin (who later became a member of Unova's Elite Four), who is the one in charge of running the facility by determining how much Castle Points (CP) are awarded to the player in the castle. He fights in her place using her Pokémon. Managing and using CP is an important factor for this facility. Darach gives away the Silver Castle Print to trainers that defeat him once and the Gold Castle Print to trainers that beat him twice.

Battle Chatelaines

=
is the crime syndicate in Kanto and Johto. In ''Pokémon Red'', ''Blue'', ''Green'' and ''Yellow'' and their remakes, ''Pokémon FireRed'', ''LeafGreen'', ''Let's Go, Pikachu!'' and ''Let's Go, Eevee!'', they desire to exploit Pokémon to further their goal of world domination. In ''Pokémon Gold'', ''Silver'' and ''Crystal'' and their remakes, ''Pokémon HeartGold'' and ''SoulSilver'', they seek to find and bring Giovanni back to lead.

* Giovanni (): An expert in Ground-type Pokémon and the leader of Team Rocket. He runs the Viridian City Gym in ''Pokémon Red'', ''Blue'', ''Green'' and ''Yellow'' and their remakes, ''Pokémon FireRed'' and ''LeafGreen''. He later disappears and is not seen again, though Team Rocket attempts to locate him in ''Pokémon Gold'', ''Silver'' and ''Crystal'' and their remakes, ''Pokémon HeartGold'' and ''SoulSilver'', the latter of which he appears via a downloadable event. He also appears as the final boss of Pokémon Ultra Sun and Ultra Moon in the postgame story event, when Team Rainbow Rocket takes over, as Giovanni is the leader. However, he is a different one from the other games, as he comes from an alternate reality where Team Rocket took over the world. His team in the game remains the same in both versions, but his Mewtwo uses a different Mega Evolution depending on the version, having a Mega Mewtwo X in Ultra Sun, and Mega Mewtwo Y in Ultra Moon.
* Dalton (): A Juggler who is a Team Rocket member.
* Jessie () and James (): They appear as mini-bosses in ''Yellow'', ''Let's Go, Pikachu!'' and ''Let's Go, Eevee!''. The duo's name is a reference to Jesse James, an outlaw. Their Japanese names are references to two famed swordsmen in Japanese history, Sasaki Kojirō and Miyamoto Musashi, who famously fought each other on the Island of Ganryū in 1612, resulting in Musashi's victory and Kojirō's death.
* Gideon (): The head Team Rocket scientist in Sevii Islands.

=Team Magma and Team Aqua

=

are the two villainous groups in ''Pokémon Ruby'' and ''Sapphire'' and their remakes, ''Pokémon Omega Ruby'' and ''Alpha Sapphire'' (depending on the game's version), which each seek to cause huge alterations to the planet's ecosystem. In ''Pokémon Emerald'', both of the groups are enemies.

Team Magma

are the player's enemies in ''Pokémon Ruby'', ''Emerald'' and ''Omega Ruby''. They wish to expand the lands by awakening Groudon.
* Maxie (): The leader of Team Magma, leading the group in their goal of waking Groudon to cause a drought to dry out the oceans and expand landmasses to make the world a better place.
* Tabitha (): One of the Team Magma Admins. He leads the group to steal the Meteorite from Professor Cozmo at Meteor Falls and brings it to Maxie at Mt. Chimney.
* Courtney (): One of the Team Magma Admins. She leads the group at the Weather Institute attempting to steal Castform. After defeat, the presumably unnamed scientist that views the battle gives you Castform.

Team Aqua

are the player's enemies in ''Pokémon Sapphire'', ''Emerald'' and ''Alpha Sapphire''. They wish to expand the seas by awakening Kyogre.
* Archie (): The leader of Team Aqua, leading the group in their goal of waking Kyogre to cause a heavy rainfall to flood the landmasses and expand the oceans to make the world a better place.

* Shelly (): One of the Team Aqua Admins. She leads the group at the Weather Institute attempting to steal Castform. After defeat, the presumably unnamed scientist that views the battle gives you Castform.

=Team Galactic

=
first appear in ''Pokémon Diamond'' and ''Pearl'', being the evil team tormenting the region of Sinnoh. They desire to make a new dimension to their preferred designs by making the mythical Red Chain to control Dialga and Palkia (depending the game's version). To accomplish this, they kidnap Uxie, Mesprit and Azelf for their plans. In ''Pokémon Platinum'', they want both but are stopped when Giratina comes out of the Distortion World and drags everything back in with it. In the anime series, they are almost successful in creating a new dimension, but are stopped when Ash and his friends save Uxie, Mesprit and Azelf, compelling Cyrus to step into the new dimension as it collapses, killing him. Later, Looker arrests Mars, Jupiter, Saturn and Charon, causing Mars to exclaim that “this is the end of Team Galactic."
* Cyrus (): The leader of Team Galactic. Although it appears he wants to work with his team to create a new dimension, he really wants to create the dimension solely for himself, making it one devoid of emotions that he sees as weak and useless.
* : One of Team Galactic Commanders. She leads the group's actions at the Valley Windworks and also the assault at Lake Verity. In ''Platinum'', she displays a dislike towards Charon and quits Team Galactic afterwards, looking to save Cyrus from the Distortion World.
* : One of Team Galactic Commanders. She leads the team at Eterna City's headquarters when they are investigating the city's Pokémon statue and the assault at Lake Acuity. In ''Platinum'', after Mars quits, Jupiter decides to leave Team Galactic as well.
* : One of Team Galactic Commanders. He leads the operations at Lake Valor as well as the group's headquarters in Veilstone City. After Cyrus's defeat, he decides to lead Team Galactic on a more virtuous mission of seeking alternative energy sources.
* Charon (): One of Team Galactic Commanders, introduced in ''Platinum''. He designs the devices that allow the group to control Uxie, Mesprit and Azelf and bring forth Giratina. He later tries to lead the group in obtaining the power of Heatran, but the player defeats him and he is arrested by Looker. The player can read his notes and it is hinted that he befriended the Rotom found near Eterna City.

=Team Plasma/Neo Team Plasma

=
is the antagonistic group in Unova games. In ''Pokémon Black'' and ''White'', they seeks to liberate Pokémon from humans. They are led by a boy known only as N and the Seven Sages who will capture Zekrom and Reshiram (depending on the game version), intending to use the Dragon Pokémon to force people to abandon capturing Pokémon. In reality, N is a pawn used by his adoptive father Ghetsis, one of the Seven Sages, who raised him for the sole purpose of being able to tame the legendary Pokémon and then disposing of him, so that he can take control of Unova. In ''Pokémon Black 2'' and ''White 2'', they intend to use the power of Kyurem to take over the Unova region and the rest of the world.
* : N is the king and leader of Team Plasma. He is a very mysterious trainer who shows up at random and inconvenient times and believes that all humans and Pokémon should be separated. He is almost always seen using Pokémon that can only be found in the area that he is fought in. He was forced to grow up with abused Pokémon, as a plot by his adoptive father, Ghetsis, so that he would want to liberate all Pokémon from humans. By following through with the plan, he captures either Zekrom in ''Black'' or Reshiram in ''White'' (the player will capture the opposite colored one) in order to show the world his power so that they will follow through with his plan to liberate all Pokémon. N returns in ''Black 2'' and ''White 2'' in a supporting role, enabling the games' mascot Kyurem to transform into its iconic form for the game version. In the end game, N can be challenged, using his legendary Pokémon from the previous game and upon defeat the Dragon transforms into a Key Item the player can use to capture the Dragon. After another in-game event, N becomes a character the player can challenge on a monthly basis, with the team changing with the games' seasonal cycle. His full name is .
* The : The high-ranking members of Team Plasma. Throughout the course of the gameplay, the player encounters each of the sages but will not be able to battle them. After the defeat of N and before becoming the Pokémon Champion, the player must locate all of the Sages scattered throughout the Unova region.
** Ghetsis (): Ghetsis is the true leader of Team Plasma and N's father, having raised the boy to serve as a charismatic leader while secretly running the true operations of the group behind the boy's back. For much of ''Black'' and ''White'', he presents himself as a seemingly benevolent, well-meaning figure, but is steadily hinted at - and ultimately revealed as - the main villain of both sets of games and the main antagonist, rather than N. When N was only a child, Ghetsis kept him away from humans and closer to abused Pokémon, so that he would later develop resentment against humans who live side by side with their Pokémon and not realise how many good people actually existed. Because of this, Ghetsis was able to easily manipulate N into believing that he would be the "hero" that would help free all the Pokémon world from their owners. Afterwards, it is implied that Ghetsis planned to get rid of N once he had accomplished his mission: becoming the sole controller of Unova's Pokémon and using them as an army to conquer the entire world and rule it as a dictator. However, the actions of the player - who has helped inspire N to see beyond his old views - lead to N's defeat. This infuriates Ghetsis, who reveals his true colors and attempts of complete world domination to stop the player himself, along with calling N a 'freak without a human heart'. After his defeat, he begins losing his mind, but retains enough clarity to escape with the help of his loyal servants, the Shadow Triad. In ''Black 2'' and ''White 2'', he uses Colress as a proxy leader of Neo Team Plasma to conceal its own identity. When met, he will state that Kyurem is an empty shell and that he will pour his ambitions into that shell. He uses the Legendary Pokémon to freeze Unova and its people, with the ultimate goal of conquer the world with its great power. In Giant Chasm, he will command Kyurem to freeze the player alive with the Pokémon's signature move, Glaciate, but will be stopped by N. Unfortunately, he predicted that N's love for Pokémon will lead him to Kyurem and then merges Kyurem and Zekrom (''Black 2'') or Reshiram (''White 2'') to create Black Kyurem (''Black 2'') or White Kyurem (''White 2''), respectively. After Black/White Kyurem is defeated, Ghetsis then challenges the player to a battle. After losing, he loses the last of his sanity and the Shadow Triad move him away - later revealing that his mind has completely broken from the shock of his failures. His full name is .
**Zinzolin (): Associated with the color purple. Despite claiming to dislike the cold, he can be found in Cold Storage after defeating Ghetsis. He seems to specialize in Ice types.
** Rood (): Associated with the color red. He returns in ''Pokémon Black 2'' and ''White 2'' as part of the old Team Plasma and is battled at their warehouse in Driftveil City. He seems to specialize in the Normal type. He entrusts N's Zorua into the player's care and assists the player at the Giant Chasm against Ghetsis' faction.
** Gorm (): Associated with the color blue.
** Bronius (): Associated with the color brown.
** : Associated with the color yellow.
** Ryoku (): Associated with the color green.
* The Shadow Triad (): Three ninja-like young men who are Ghetsis's faithful servants because he once saved their lives. They have the ability to teleport and usually "escort" the player to N or Ghetsis. After Ghetsis's defeat and arrest (and later unexplained break-out), the Shadow Triad appears one last time on the Marvelous Bridge, where they explain that Ghetsis ordered them to bring the player the three Orbs of Dialga, Palkia and Giratina (Adamant, Lustrous and Griseous, respectively) and that despite their loyalty to him, he has ordered them to not look for him. The Shadow Triad returns in ''Pokémon Black 2'' and ''White 2'' and battles the player several times in the game. They are also revealed to possess a Liepard which had evolved from a Purrloin which was stolen from the rival character's younger sister five years earlier, leading him to foster a deep hatred for the organization. At first, this includes Rood's faction as well. After Neo Team Plasma disbands, the Triad remains at Icirrus City, where they can be challenged on a monthly basis. Using the Unova Link Function unlocks a cutscene involving Cilan, Chili and Cress fighting against The Shadow Triad (and losing) - thus disbanding the rumors that the two groups are one and the same.
* Anthea (the ) and Concordia (the ): Two characters who appear towards the end of the main story of ''Black'' and ''White'' who serve N. Concordia tells the player the story of N and how Ghetsis raised him, while Anthea heals the player's Pokémon in preparation for the final battle against N. They can also be seen in the game's first opening sequence where they watch as N is crowned as the king of Team Plasma by Ghetsis. It was revealed that Anthea and Concordia are N's foster Sisters. They appear in ''Black 2'' and ''White 2'' in Rood's Pokémon volunteer house in Driftveil City, where they tell the player of Ghetsis' ambitions and what he did to further them, as well as N's early childhood before Ghetsis found him. According to them, N had spent this part of his life in a forest with a Darmanitan and a Zorua (the latter of which can be acquired from Rood) as he had distressed people with an unusual ability to commune with Pokémon.
* Dudley (): A scientist that was researching (and modifying) Genesect for Team Plasma. If the player goes to the P2 Laboratory with a Genesect in their party, an event will trigger, involving Dudley challenging the player, who has the Pokémon of the cancelled project he was working on.
* Colress (): Colress is an independent Pokémon researcher and a proxy leader of Neo Team Plasma, who works to learn about the powers of Pokémon and tries to bring out the true strength within them. He battles the player several times throughout the game to test the player's ability and the power of the player's Pokémon. He eventually aligns with Neo Team Plasma, as they will allow him to study Pokémon the way he wishes. In the main story of ''Black 2'' and ''White 2'', he is the helmsman of the Plasma Frigate, Team Plasma's primary mode of transportation. After Neo Team Plasma is defeated, he helps the group reform their ways. He can then be battled at the P2 Laboratory. He returns in ''Ultra Sun'' and ''Ultra Moon'', giving the player the means to fuse Necrozma with Solgaleo/Lunala once they catch the former and helping the player and their allies in defeating Team Rainbow Rocket in the post-game story. He has a larger and more antagonistic role in the anime, as he is building a device that would allow Ghetsis to control Reshiram and he takes control of various Pokémon, including Team Rocket's Meowth, in an effort to fine tune it. It was later destroyed by Ash's Pikachu (having resisted the device's effects) and Reshiram. He specializes in Steel-type Pokémon.

=Team Flare

=
is the evil team appearing in ''Pokémon X'' and ''Y''. Their main goal is to "create a beautiful world", which eventually manifests itself into mass genocide of all human and Pokémon life but themselves, using an ancient weapon once used by a king of Kalos, an ancestor of their leader Lysandre, from 3000 years ago. While their plan involved harnessing the power of Xerneas and Yveltal (depending the game's version), Team Flare's scheme in the anime involves controlling Zygarde and the sundial as their weapon to cause a nuclear holocaust.
* Lysandre (): The leader of Team Flare, seeking to attain eternal beauty. He follows the player's progress closely, seeking the player in his plans and revealing the history of Kalos and the king AZ, his ancestor, who nearly wiped out all life. After his identity as Team Flare's leader is revealed, he admits that he wishes to use his ancestor's weapon to enact a mass extinction, believing the Mega Ring to be central to his plans. The player ultimately defeats Lysandre and when Lysandre attempts to activate the weapon, despite the player having captured its power source Xerneas (''X'')/Yveltal (''Y''), the weapon crumbles and destroys the headquarters. Although the player and his/her friends, as well as most of the members of Team Flare, manage to escape, Lysandre is never seen escaping the destruction and therefore he is presumed dead. In the anime, using Lysandre Labs as a front, Lysandre manipulates Alain to provide him with Mega Evolution while his subordinates managed to capture the blue-core Zygarde in his plan to control both Zygarde Cores while destroying Lumoise City as a display of Team Flare's power. But after losing to Ash, Alain and a redeemed Malva, as well as losing both Zygarde Cores, Lysandre resorts to using a Zygarde fabrication created from the Megalith and have it absorb the energies of the Anistar sundial to invoke a global genocide. But the Zygarde Cores assume their 100% form to destroy the fabrication with the signature move Core Enforcer, with Lysandre seemingly killed in the process.
* : A former Team Flare admin who became a butler.
* Team Flare scientists: The scientists of Team Flare.
** Xerosic (): One of the Team Flare scientists. He is the group's head scientist, leading the building of the ultimate weapon. In the post-game, he also creates the Expansion Suit and hires Emma to be its user. At the end of the post game, he is arrested by Looker.
** Celosia (): One of the Team Flare scientists. She and Bryony lead the group in their attack on the Poké Ball Factory.
** Aliana (): One of the Team Flare scientists. She leads the group in their infiltration of Kalos's Power Plant.
** Bryony (): One of the Team Flare scientists. She and Celosia lead the group in their attack on the Poké Ball Factory.
** Mable (): One of the Team Flare scientists. She leads the group in their Frost Cavern operations, angering a native Abomasnow.

=Team Skull

=
is a gang of street thugs who are the resident villain team of Alola in ''Pokémon Sun'' and ''Moon'', secretly working with the Aether Foundation on the promise of money. They were disbanded following the events of the games.
* : Guzma is the boss of Team Skull and battles without mercy. He at one point went through the Island Challenge, but did not meet the criteria to become a captain. He has history with Professor Kukui. He can be teamed up with at the Battle Tree in Double Battles and in the ''Ultra'' versions, he helps the player defeat Team Rainbow Rocket out of his loyalty to Lusamine. After that, he appears as a possible Title Defense challenger.
* : Plumeria is Team Skull's admin and helps to keep the team in order. She cares for the grunts beneath her, making her less antagonistic than previous admins. She appears as a possible fighter in Title Defense.
* : This young man lends his strength to Team Skull as an enforcer. He places a high value on being strong in Pokémon battles. His partner Pokémon is the mysterious Type: Null, which eventually evolves into Silvally. He is Lusamine's son and Lillie's brother. He also appears as a possible fighter in Title Defense and in the ''Ultra'' versions leaves Alola post-game to travel to other regions to become stronger; he appears as a Title Defense challenger after a month has passed in those games.

=Aether Foundation

=
The is an organization appearing in ''Pokémon Sun'' and ''Moon'' seemingly dedicated to the conservation of Pokémon. However, it is revealed that they are also researching the Ultra Beasts and while they are not technically a criminal syndicate, their president sought to harness the power of Cosmog to bring the Ultra Beasts into Alola (in the original games)/travel to Ultra Megalopolis to battle Necrozma (in the ''Ultra'' versions) with no regard for the consequences of doing so.
* : The leader of the Aether Foundation, the mother of Lillie and Gladion and the real villain of the original ''Sun'' and ''Moon'' games. She is obsessed with the Ultra Beasts, specifically the Nihilego species having fallen under their influence; Gladion speculates her fixation started after her husband vanished while studying them. She went as far as unleashing them upon Alola by overclocking Nebby's power before wanting to live a solitary life amongst the Nihilego in their home realm. She then ends up allowing herself to be taken over by a Nihilego (which she caught while the player was in Alola) at the games' climax in a last-ditch attempt to destroy the heroes (making her the only villain in the franchise whose final battle is fought against as a mutant version of themselves). While she is now living in Kanto to have the last of the Nihilego poison removed from her and trying to rebuild her relationship with Lillie, her ultimate fate in the original games remains unknown. However it is implied that she is now wanted by the International Police for her actions against Alola while she was possessed. The ''Ultra'' versions depict her in a completely different light; devoid of Nihilego's influence and therefore her Ultra Beast obsession, believing she is doing the right thing, working also with the Ultra Recon Squad and harnessing Nebby's power so that she can fight Necrozma, but is defeated easily by the stealer of light. She reforms at the end, giving her children the independence she had denied them for so long and choosing not to directly interfere with their lives anymore, but is captured by Team Rainbow Rocket and taken hostage in the post-game. After Team Rainbow Rocket's defeat, she then appears as a possible Title Defense challenger at the start of every month, a role previously taken by Faba (see below)
* : The Aether Foundation's admin. He challenges the player multiple times to stop the player when Lillie gets kidnapped. In the original games, he also appears as a possible fighter in Title Defense, appearing every start of the month, having been demoted from his position of Branch Chief. In the post-game story of the ''Ultra'' versions, he betrays the Aether Foundation to Team Rainbow Rocket for his own benefit. Because of this, he is demoted to the position of intern following Giovanni's defeat, with Lusamine taking his place in Title Defense in these games.
* : The vice-chief of the Aether Foundation. Unlike the other two, she helps the player attempt to stop Lusamine's plans. She also appears in the post-game, helping the player with the Ultra Beast mission in the original versions.

=Ultra Recon Squad

=
The is an organization appearing in ''Pokémon Ultra Sun'' and ''Ultra Moon''. They main goal is to investigate Ultra Wormholes, Ultra Beasts and return the light that was stolen from their home by Necrozma.
* : One of the members of the Ultra Recon Squad. He travels to Alola with Zossie in ''Ultra Sun'', but stays at the Ultra Megalopolis in ''Ultra Moon''.
* Zossie (): One of the members of the Ultra Recon Squad. She travels to Alola with Dulse in ''Ultra Sun'', but stays at the Ultra Megalopolis in ''Ultra Moon''.
* Soliera (): One of the members of the Ultra Recon Squad. She travels to Alola with Phyco in ''Ultra Moon'', but stays at the Ultra Megalopolis in ''Ultra Sun''.
* Phyco (): The captain of the Ultra Recon Squad. He travels to Alola with Soliera in ''Ultra Moon'', but stays at the Ultra Megalopolis in ''Ultra Sun''.
* Rhi: A member of the squad introduced in ''GO'' as a temporary substitute for Professor Willow since GO Fest 2022.

=Team Rainbow Rocket

=
is the crime syndicate in the post-game of ''Pokémon Ultra Sun'' and ''Ultra Moon''. They plan to rule all worlds with an army of Ultra Beasts. They consist of alternate versions of all the evil team leaders from previous games, but unlike the events of the previous games, when they were defeated, they were successful in their plans. Each team leader wields a powerful Legendary Pokémon from their respective regions.
* Giovanni (): An alternate version of Giovanni is the leader of Team Rainbow Rocket. He has Mewtwo as part of his team. This Giovanni was successful in leading Team Rocket to take over the world and completely upgrading to Team Rainbow Rocket. Depending on the game's version, Mewtwo will Mega Evolve into either Mega Mewtwo X (''Ultra Sun'') or Mega Mewtwo Y (''Ultra Moon'').
* Maxie (): An alternate version of himself appeared as a member of Team Rainbow Rocket. This Maxie was successful in expanding the land but fell into a large fissure at that very moment and ended up in the game's world. He has Groudon as part of his team.
* Archie (): An alternate version of Archie appeared as a member of Team Rainbow Rocket. This Archie was successful in expanding the sea but was engulfed by a large wave during the moment of his victory and ended up in the game's world. He has Kyogre as part of his team.
* Cyrus (): An alternate version of Cyrus appeared as a member of Team Rainbow Rocket. This Cyrus was successful in recreating the universe but was engulfed by a mysterious shadow during the moment of his victory and was transported to the game's world.
