List of Pokémon temporarily owned by the Team Rocket trio

When the St. Anne sank, James tried using Magikarp to help them escape, but it only made their situation worse. After finally making it to the surface, Meowth tried to take a bite out of it. His teeth broke off from the hard skin, and James, angry at how useless it was, kicked it into the ocean. The kick caused Magikarp to evolve into Gyarados. Using Dragon Rage, James' Gyarados and several other Gyarados sent Team Rocket, Ash and his friends flying. James' Gyarados was never seen again.

Gyarados' known moves are Splash and Dragon Rage.

James of Team Rocket sent it out to battle the instructor's Graveler, at which James was overjoyed, exclaiming that he had been destroyed by Pikachu's attacks so many times that he knew them all by heart. However, Pikachu's Thunderbolt had no effect on the Graveler, at which James sent out Ivysaur and Charizard, and subsequently was expelled on the spot. He later used Pikachu to attack the instructor with Thunder, but the instructor told Ivysaur, Charizard, and Pikachu to attack Team Rocket instead.

Pikachu's known moves are Thunderbolt and Thunder.

James of Team Rocket sent it out along with Charizard to battle the instructor's Graveler. However, since two against one was against the rules, James was expelled on the spot. He later used Ivysaur to attack the instructor, but the instructor told Ivysaur, Charizard, and Pikachu to attack Team Rocket instead.

Ivysaur's only known move is Vine Whip.

Later in the episode this Weepinbell evolves into Victreebel, and it tries to gobble Jessie (much like the previous Victreebel did with James). This causes her to command her Arbok to send the Flycatcher Pokémon flying. At the same time the Magikarp salesman realizes that James' original Victreebel will not obey him, and he kicks it away. The two Victreebel meet, fall in love, and skip off into the forest.

Victreebel's known moves are Sweet Scent, Razor Leaf and Vine Whip.

When he showed it to Jessie and Meowth, they were less than impressed with the Chimecho. Meowth immediately realized it was a fake, and when it started falling apart, James rubbed it with a rag. All the paint came off, and the Chimecho was revealed to be a fake. Before James could do anything, the Hoppip floated away, never to be seen again.

Using their Donphan and Steelix, the two friends tried to defeat Team Rocket's newly acquired Pokémon. However, the Aggron and Charizard were stronger and gained an early advantage. The battle was ended when Max discovered that the two Trainers were indeed Team Rocket in disguise. With the help of Forrest, Team Rocket were sent blasting off and Pewter Gym was safe.

At the end of the day, Delibird returned and took the two Pokémon back, as the Charizard and Aggron were originally intended for Cassidy and Butch, respectively. Before Team Rocket could question what it was doing, it was gone, and Aggron and Charizard haven't been seen since.

Aggron's known moves are Mega Punch, Hyper Beam and Water Pulse.

Kingler's known moves are Crabhammer, Harden and Bubble.

Machamp's only known move is Karate Chop.

None of Rhydon's moves are known.

Blastoise's known moves are Skull Bash, Bubble, Withdraw and Hydro Pump.

Charizard's known moves are Dig, Iron Tail, Scary Face and Flamethrower.

Later, Team Rocket was seen at a lake letting Jessie's "Feebas" swim around in a stream. The paint started to run, and soon it was revealed that the Feebas was actually a Magikarp. This discovery infuriated Jessie, and Team Rocket sought out the salesman to demand a refund. When they found the salesman, Ash and his friends were already there. A battle between Cacnea and Dustox against Pikachu and Spoink ensued, during which the salesman escaped, and Magikarp was completely lost track of. Team Rocket was defeated in the end and the pearl was returned to Spoink. The Magikarp has never been seen again so it is believed not to belong to Jessie anymore.

Main article: Harley's Cacturne

In New Plot, Odd Lot!, Harley lent Jessie his Cacturne to help her get a ribbon in the Mulberry City contest, in an effort to keep May from seizing her last chance to enter the Kanto Grand Festival. When Harley introduced it to Jessie, Cacturne instantly fell in love with her. Harley explained this happened because he (Harley) and Jessie were soul-mates. Jessie and Cacturne's performance in the appeals round allow Jessie to advance.

Cacturne was returned to Harley the following episode.

Banette was returned to Harley at the end of the episode.

Using their disguises, they challenged Brock and Ash to a double battle. Team Rocket sent out their newly acquired Pokémon, while Brock and Ash sent out their Steelix and Donphan, respectively. Unfortunately, Team Rocket got an early advantage and appeared to be winning. The victory was short-lived when Max discovered Meowth stealing all of the Gym's Poké Balls. It was then revealed that the two were indeed Team Rocket. With the help of Forrest, they were sent blasting off.

At the end of the day, Delibird returned to take the Poké Balls back, as the Charizard and Aggron were originally intended for Cassidy and Butch, respectively. Before Team Rocket could plead with Delibird to return them, it had flown away.

Charizard's known moves are Flamethrower and Fire Spin.

Main article: Dawn's Ambipom

In Borrowing on Bad Faith!, Jessie heard of an informal Pokémon Contest, as well as its grand prize of a year’s supply of fresh fruit. She asks for James' Carnivine, but he refuses. The trio then hears Aipom crying and rush to find it, not realizing it belongs to Ash. Spotting the Pokémon atop a precipice, Jessie decides to save the monkey Pokémon. Upon seeing how she helped his Pokémon, Ash reluctantly thanked Jessie. Jessie decided to use the situation to her advantage, and asked the twerp if she could use Aipom in the contest. Ash believed Aipom didn't want to, but Aipom actually did, which Meowth seconds. Ash decides to let it happen, though reluctantly. The duo eventually win the contest, besting Dawn's then-inexperienced Pachirisu.

When the Team takes off in the Meowth balloon, Aipom takes off with them, hoping to grab the fruit for herself. After Team Rocket unsuccessfully try to stop her, Ash tells Aipom to use Swift on the balloon, blasting them off. Aipom then returns to her Trainer, and the episode ends.

Smoochum's only known move is Sweet Kiss.

Hippowdon's only known move is Dig.

Sadly, when the vaccine was released by Nurse Joy, one of them hit Team Rocket, knocking Porygon unconscious. When fleeing Dr. Akihabara's ruined house, they left Porygon behind for reasons unknown.

Because its only appearance was in an episode that aired only once in the world, it is the only Pokémon owned by a main character at some point that virtually no longer exists even in Japan, and the only Pokémon owned by a main character to have never been seen officially outside of Japan.

Porygon's only known move is Sharpen.

Main article: Delibird (Team Rocket)

Delibird first appeared in Dues and Don'ts under the ownership of a Rocket Scout. She claimed that she and the Delibird were trying to recruit new members for Team Rocket. When Jessie and James told her that they were Team Rocket members, she said that they weren't in the system. James pulled out his membership card, and the scout informed them that because they hadn't paid any of their dues, they had been kicked out of Team Rocket.

The scout then told them that if they defeated a Trainer, they would be allowed back in. Using Delibird, Team Rocket battled Ash, and despite the fact that he won, the scout allowed them to rejoin. But she also told them that her Delibird would be following them around to collect their dues that they had still not paid.

While it appears the Delibird has stopped pestering the trio for their dues, it still appears from time to time as a courier, as seen in Grating Spaces and The Thief That Keeps on Thieving!.

Main article: Ash's Pikachu

In A Scare to Remember, an explosion caused by the destruction of Team Rocket's "Mean and Nasty, Grumpy Grabber Mark One" machine causes Pikachu to fly far away from Ash and company with Meowth. The resulting impact causes Pikachu to lose his memory. Meowth seizes the opportunity, telling the Mouse Pokémon that he belongs to Team Rocket and has since the day he was born. The amnesiac Pokémon believes him and the duo rendezvous with Jessie and James.

By the end of the episode, Ash manages to reverse Pikachu's amnesia, bringing him back to the side he belongs on.
