In Pokémon Red, Blue, Yellow, FireRed and LeafGreen, the player must foil several schemes by Team Rocket, including those in Celadon City, Saffron City, and, in FireRed and LeafGreen, the Sevii Islands, specifically the fifth island. Giovanni is the final Pokémon Gym Leader of the Viridian City Gym, and the team is disbanded after his gym battle defeat. However, in FireRed and LeafGreen, a handful of Team Rocket operatives continue to operate in the Sevii Islands until they are defeated.
Team Rocket Grunts most often use fierce-looking Pokémon. Their chosen Pokémon tend to be of the Poison type. Their leader, Giovanni, uses mainly Ground-type Pokémon.
In other games and regions, the crime syndicates are not related to Team Rocket.
Jessie (ムサシ, Musashi?), James (コジロウ, Kojirō?), and Meowth (ニャース, Nyasu?) are the main characters of Team Rocket. While they set out to steal Ash Ketchum's Pikachu and various other Pokémon in almost every episode, they usually fail in the end. They use various disguises, traps, and schemes to trick Ash's group into a false sense of security, and after being revealed, they give a poetic speech, known as their motto, that often changes slightly throughout each season. After failing, they are often sent "blasting off" by an explosion or a Pokémon's attack. They are constantly out to appease their boss, Giovanni, though he finds the group to be incompetent.
Jessie is a loudmouth who often abuses the other two. She grew up in a poor foster family, while her mother focused on missions from Team Rocket. She is voiced by Megumi Hayashibara in the Japanese version, Rachel Lillis during the first eight seasons of the English anime and Michele Knotz from the ninth season onwards. James is portrayed as whiny and submissive. He grew up in a rich household that he ran away from after his parents set up an arranged marriage. James is voiced by Shin-ichiro Miki in the Japanese version, Ted Lewis for the first thirteen episodes of the English anime, Eric Stuart until the end of the eighth season, and Jimmy Zoppi from the ninth season onwards. Meowth is a unique Pokémon with the ability to speak, which came about while trying to impress a female Meowth. Meowth is voiced by Inuko Inuyama in the Japanese version, Nathan Price for the first thirty episodes of the English anime, Maddie Blaustein until the end of the eighth season, and Jimmy Zoppi from the ninth season onward.

In the manga, Blaine is a former Team Rocket Scientist who had combined the DNA of Mew with his own DNA, creating Mewtwo. However, he gained the DNA of Mewtwo as well, giving him the ability to track Mewtwo. The manga also shows Koga, Lt. Surge, and Sabrina as high-ranking operatives of Team Rocket. A major difference between the manga and other versions of Team Rocket is that several Gym Leaders are antagonists in the manga. It is also noted that at the end of the Kanto Saga after disbanding from Team Rocket, that Jessie and James reveal to Red in a letter that they are married and having a child.
In this continuity, Team Rocket is apparently an acronym for “Raid On the City, Knock-out, Evil Tusks.”
The Mask of Ice kidnapped Blue, Silver, Shum, Cart, Will and Karen as children, and raised them as his servants. Blue and Silver escaped soon after, but the rest of them remained in his clutches. After Giovanni disbanded Team Rocket, the Mask of Ice recruited the Rocket Grunts that were left behind, forcing those who are not interested by controlling them with masks. However, former Team Rocket Executives Lt. Surge, Sabrina, and Koga were not recruited by Mask of Ice.
The Mask of Ice’s true identity is that of Pryce, the Gym Leader of Mahogany Town. In the final chapters of G/S/C, he is somewhat defeated by Gold and his Pichu and sent into the voids of time.
is a group of thieves/peacemakers in the Hoenn Region. They specialize in Water and Dark type Pokémon.
Team Aqua is based in a giant nuclear submarine out at sea, with a helicopter for land-to-sea travel. The team members all wear striped black and white shirts with jeans. Their do-rags bear a white skull-and-crossbone in the shape of the letter "A". Like Team Magma, Team Aqua is run by a ruthless Commander. Shelly (Izumi in the Japanese version) is referred to as Team Aqua Leader, though the actual leader is Archie (Aogiri in the Japanese version).
Team Aqua are likened to a band of pirates and are experts in the field of Oceanography as well as water Pokémon. They only exist in the Hoenn region and do not recognize Team Rocket, unlike Team Magma. Team Aqua are the bitter antagonists of Team Magma and are currently in a brief war with each other. Team Aqua's main goal is to [partially] flood the world as a giant ocean for their water Pokémon, believing that by doing this they will be making the world a better place. To that end, they will awaken Kyogre from its slumber.
Team Aqua is slightly less vicious than Team Magma (and vice versa in the manga), and has more females in its group, but they have a male leader. Although they seem bad they turn out to only want to stop Team Magma. Their main thoughts about Ash Ketchum are not made clear, though Archie and Maxie (who seemed to have a relationship of sorts with him once) do see him as a pest. Team Aqua is well-known in the Hoenn region, and they often blackmail local fishermen into telling lies.
In the anime, he is a ruthless villain who was once a friend of Maxie. However, as he became more advanced in Pokémon, he became more greedy, and organized Team Aqua and battled Team Magma for world control. In episode 374 ("The Scuffle of Legends"), Archie absorbed the Red Orb into his body, gaining the power to control Kyogre, but the orb was expelled from his body because it could not take the power strain of the orb. Lance ordered his Dragonite to catch him. Archie was laid down by Shelly. Shelly desperately tries to wake him up. When Archie finally wakes up, he has no memory of the event. In the games, he is a misguided individual who believes he is doing the right thing.
The group all wear dark-red uniforms with a black stylized "M" made of either mountains or volcanoes on their shirts. The head of Team Magma is Maxie (Matsuba in the Japanese version), but his second in command is The Commander, named Tabitha (Homura in the Japanese version). Another notable member of Team Magma is Brody (Ban'nai in the Japanese version), who owns a Ditto and is able to imitate the voice and appearance of anyone he wishes, earning him the name of 'The Man of a Thousand Faces.' Team Magma often use equipment that is normally used for experiments with high temperatures. No vehicles are shown in the anime except for the Commander's helicopter.
Team Magma are bitter rivals of Team Aqua. Though Team Magma does not exist outside the Hoenn region, they do know the work of Team Rocket, who have no Hoenn branch. Team Magma's main purpose is to expand the land mass, believing that by creating more room for life on land that they will be making the world a better place. To that end, they'll awaken Groudon from its slumber.
Team Magma frequently make appearances in Pokémon Advanced, and are seen merely as "big brothers" rather than a proper archrival. They eventually disappear after a battle between Groudon and Kyogre. It has been verified that neither Team Aqua nor Team Magma will be appearing in any future Pokémon episodes. However, Brody appears again in the episode The Ribbon Cup Caper after the disbandment of Team Magma. Butler and Diane also have a brief cameo in the credits of the Pokemon movie "Jirachi Wish Maker".
Maxie met Ash in the episode "Gaining Groudon," and told him of his dreams. He also told Ash about the Blue Orb, which could control Groudon, and with it in his hands, he could make life better for him. Suddenly, Pikachu got possessed by the Blue Orb. It controlled Groudon, and a cataclysmic battle began, resulting in Groudon's victory.
After the battle, Maxie thanks Ash, realizing that the land of Hoenn was perfect the way it is. He led Team Magma away and has not been seen since...
In Sapphire, the sitaution is reversed. Team Magma befriends the protagonist and attempts to stop Team Aqua from expanding the sea so that more Pokémon can live in the sea. Team Aqua steals the Red Orb from Mt. Pyre to awaken the legendary Pokémon Kyogre. Like Groudon, Kyogre flees after being freed, and brings eternal rainstorms. The player enters the Cave of Origin to revert Hoenn back to normal.
In Emerald, both teams are now the enemy. In Ruby and Sapphire, both teams had their secret hideout over the water, but in Emerald, Team Magma has set up camp in a place called Jagged Pass, where Maxie awakens Groudon. Like in Sapphire, Archie steals the submarine and goes down to Seafloor Cavern to awaken Kyogre. Groudon and Kyogre begin fighting at Sootopolis, resulting in alternating sunshine and rain. The player travels to Sky Pillar and awakens the legendary Pokémon Rayquaza, who calms the two legendaries. Afterwards, Maxie and Archie return the two Orbs to Mt. Pyre.
In Diamond and Pearl, Team Galactic state their intention to create a new world order . However, only Cyrus and his commanders know the true details (and even then, Saturn is not entirely clear on this)--that this will first entail the total destruction of the current world to allow the presence of the new. They kidnap the legendary Lake Trio (Uxie, Mesprit, and Azelf) and extract crystals from them to create an item known as the Red Chain, which shackles and controls a Pokémon, yet keeps their full power (according to Cyrus' files, they do not plan to keep their target in a Poké Ball, in which they claim that it will restrain its full power). The player infiltrates Galactic's headquarters and defeats Cyrus, so he allows the player to release the three after beating Saturn. At the Spear Pillar, Cyrus uses the Red Chain to bring the legendary Pokémon Dialga (in Diamond) or Palkia (in Pearl) out, planning to use their power to distort spacetime and so create the new universe, over which he will be the new deity (or so he thinks). However, the Lake Trio come back to nullify the legendary's power and break the Red Chain, interrupting the ritual. After this, and Cyrus's failure to defeat the player, most of Team Galactic disappears including Cyrus himself. Only a handful remain in Veilstone City, led by Saturn, who has renounced his earlier extremism and decided to found a new, more benevolent Team Galactic.
In Pokémon Platinum however, Team Galactic plans to captivate both deities of time and space, resulting in the interruption of an enraged Giratina, the third Sinnoh deity who represents dimension, chaos, and death. The player will have to chase down Cyrus, now infatuated with the power of the before-unknown Giratina, to an eerie dimension known as the Torn World(Yaburareta Sekai), in which Giratina has resided for countless ages.
In the anime
Team Galactic has made several appearances in the anime. So far, only two grunts and Saturn have appeared. They first appeared in A Secret Sphere of Influence!, though it was only a brief cameo at the end. They assigned the Team Rocket trio of Jessie, James, and Meowth to steal the Adamant Orb for them. Both Brock and Officer Jenny believed that the trio had been assigned to this work by Butch and Cassidy or Pokémon Hunter J.
In their next appearance in Journey to the Unknown!, Saturn brings the two grunts into the Solaceon Ruins. The Team Rocket trio observe them, following them inside. Using three plates, Saturn obtains a cube inside of the ruins, enraging the Unown and causing general chaos inside of the ruins. Before leaving, Saturn thanks the Team Rocket trio for their assistance in the earlier episode and his group escapes with his Bronzor.
Team Galactic appeared again in Enter Galactic!, where Saturn appears yet again. After exposing the cube obtained in Journey to the Unknown! to the Veilstone City meteorites, it transforms into the Spear Key. This episode is also the time when Ash and his friends finally encounter them. Their mission this time is apparently to steal some of Veilstone City's meteors. Saturn also battles Brock with their Toxicroak and Croagunk, respectively. However, no thanks to Ash, Dawn, Officer Jenny, and Paul's Electabuzz, the battle ends up in a draw and the mission is a complete failure, leaving Team Galactic to retreat. It is currently unknown why they wanted to steal the meteorites.
They will appear again in DP096 and DP097. Mars, Jupiter and Cyrus will make their debut in this episode.
Like Team Rocket, Team Aqua and Magma and Team Galactic it has a large army of Peons (known as Grunts in the hand held pokemon games) unlike them Cipher can also call on the support of almost all of the criminal underworld of Orrie.
