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's Gyarados and several other Gyarados sent Team Rocket, Ash and his friends flying. James's Gyarados was never seen again.

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's original Victreebel will not obey him, and he kicks it away. The two Victreebel meet, fall in love, and skip off into the forest.

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.

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.

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.

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.
