Released Pokémon

Released Pokémon are that have been by a Pokémon Trainer, but are sent back into the .
==In the core series==
In the core series Pokémon games, Pokémon can be released using the Pokémon Storage System. However, a Pokémon cannot be released if it is the only Pokémon in the player's party. Once the Pokémon is released, it is removed from the player's possession and cannot be encountered again. Releasing a Pokémon is useful if a player needs to free up space in the Pokémon Storage System. Pokémon Eggs cannot be released within these games.
Starting in Generation VIII, if the Pokémon is holding an item when it is released the item is returned to the player’s bag.
====Pokémon Yellow====
In , it's not possible to release the received by the player at the beginning of the game, or any other Pikachu with the same original Trainer and original Trainer ID as the player. If the player tries to release it, Pikachu complains and the attempt fails, but this doesn't affect Pikachu's friendship. Pikachu may still be traded to another game and released there (including a separate Pokémon Yellow game with a different Trainer name and/or ID). If Pikachu is traded to another game, evolves into , and is traded back to its original game, it can be released normally in its original game.
Pikachu may be released normally like any other Pokémon in the , the English Pokémon Stadium, or Pokémon Stadium 2, connected to Pokémon Yellow via Transfer Pak.
====Generations III–IV====
In Generation III and Generation IV, if the player attempts to release a Pokémon that is the only Pokémon in their party or PC that knows a certain HM move, it will immediately return. In Generation III, these moves are and . In Generation IV, they are Surf, , and , as well as in .
====Generation V onward====
Fusions of Pokémon (Black and White , Dusk Mane and Dawn Wings , and Ice Rider and Shadow Rider ) cannot be released unless separated.
====Pokémon: Let's Go, Pikachu and Let's Go, Eevee!====
In Let's Go, Pikachu! and Let's Go, Eevee!, releasing Pokémon is also called transferring, like in Pokémon GO. A player can transfer up to 30 Pokémon at once to Professor Oak, who will award one stat-specific Candy (of varying sizes) for each Pokémon transferred, each Candy's stat corresponding to what that Pokémon may yield if caught in the wild. For every 50 Pokémon of a common species the player transfers, Professor Oak will award a Candy specific to that Pokémon's species. After every transfer, Professor Oak will tell the player the total number of Pokémon that have been sent over.
The player's and any party Pokémon cannot be transferred. Transferring a , , or Mythical Pokémon (other than https://www.youtube.com/watch?v=Exz3_3plffA) will first display the warning message "Are you really sure you want to send this Pokémon? You can't get it back!". Attempting to transfer a Pokémon marked as favorite will display a prompt asking the player if they want to unfavorite it first.
====Pokémon Legends: Arceus====
In Pokémon Legends: Arceus, the can release their Pokémon from the pastures, and may release multiple at once. Released Pokémon sometimes leave behind Grit Dust, Grit Gravel, Grit Pebble, or Grit Rocks. If the player attempts to release a Legendary Pokémon, Mythical Pokémon, or Shiny Pokémon, a warning will appear, stating:
You'll be releasing a very rare specimen.
Are you sure you wish to proceed?
Until the story is finished, the player can't release or due to them being mandatory for the final battle.
==In the side series==
===Pokémon Stadium series===
In the , the English Pokémon Stadium, and Pokémon Stadium 2, there is an option to release Pokémon from the core series games connected via Transfer Pak. The first two Stadium games are only compatible with the Generation I games, while the third game is compatible with both Generation I and Generation II games. It is only possible to release Pokémon if the player has saved the core series game at a Pokémon Center. The player is able to release Pokémon from the party, the Boxes in the core series game, and from the Boxes in the Stadium game cartridge.
* In the , the player is able to go from the main menu to the "Organize" and then the "Pokémon" screen, where the Release button is a waving hand symbol. When the player presses the Release button, the game displays a list with the party and the boxes. The player is required to select one of these places first, and then choose one or more Pokémon to release.
* In the English Pokémon Stadium, the player is able to go from the main menu to the Pokémon Lab. There is a PC at the lab, with an option "Pokémon". The Pokémon screen includes the Release button, which is a waving hand symbol like in the previous game.
* In Pokémon Stadium 2, the player is able to go from the main menu to the White City and then to the Pokémon Lab. Like in the previous game, there is a PC in the lab, with an option "Pokémon". Unlike in the previous games, this time the Release button is an emoji moving to the side.
In the English Pokémon Stadium, as well as Stadium 2, the player's party is displayed by default on the left side, while the first Box is also available by default on the right side. The player may press the Release button and choose any Pokémon from the party, or alternate between left and right sides by pressing L and R. Alternatively, the player may choose any of the available places (party and Boxes) by using the options "Choose left Box" and "Choose right Box" (English Stadium) or "Check the window contents" (Stadium 2) prior to releasing Pokémon.
In all three Stadium games, once the player attempts to release a Pokémon, the game asks for confirmation. If the player agrees, a "Bye!" sound is heard and the Pokémon is released. Once the player presses B to leave the list of Pokémon, there are three options: "Save and quit", "Quit without saving", and "Cancel". The player is able to undo the act of releasing Pokémon by quitting without saving. However, once the player has released Pokémon and saved, that act is irreversible.
In the Japanese Pokémon Stadium, it's not possible to release the last Pokémon in the party. The act of pressing Release and then selecting the party results in an error message if there's only one Pokémon there. However, in the English Pokémon Stadium and Pokémon Stadium 2, it is possible to release the whole party and then move Pokémon from the Boxes to the party, or alternatively just release all Pokémon from the party and the Boxes. In these last two games, if the party is empty, the act of releasing Pokémon can't be saved—the option "Save and quit" becomes unavailable.
Even though the received in is unable be released in its own game, it can be released normally like any other Pokémon in any of the three games of the Pokémon Stadium series. Similarly, Pokémon Eggs may be released in Pokémon Stadium 2 despite being unable to be released within any main series game.
==In the spin-off games==
===Pokémon GO===
In Pokémon GO, the player can choose to transfer a Pokémon to Professor Willow. Pokémon transferred to Professor Willow cannot be taken back, equivalent to releasing the Pokémon in the core series games. When a Pokémon is transferred to the professor, the player will receive a for that Pokémon's species. Players who have reached Level 31 (Level 40 prior to June 1, 2022) or higher have a chance of receiving a Candy XL when a Pokémon is transferred.
Transferring a Pokémon to Pokémon: Let's Go, Pikachu! or Let's Go, Eevee! or to Pokémon HOME has a similar effect to transferring to Willow, although 100 XP is also awarded in the former case.
===Pokémon Mystery Dungeon series===
In the , the player can remove Pokémon from their team by saying farewell to them. In Pokémon Mystery Dungeon: Red Rescue Team and Blue Rescue Team, this can be done by visiting them in their Friend Area. In Pokémon Mystery Dungeon: Explorers of Time and Darkness, and Pokémon Mystery Dungeon: Explorers of Sky, this can be done at the Chimecho Assembly. In Pokémon Mystery Dungeon: Gates to Infinity, this can be done at the Quagsire Assembly. In Pokémon Super Mystery Dungeon, due to the removal of random recruitment, Pokémon cannot be removed once they have connected with the player's team.
In Red Rescue Team and Blue Rescue Team and Explorers of Time, Darkness, and Sky, if or Mythical Pokémon are said farewell to from their Friend Area or Chimecho Assembly, they will reappear in dungeons again, unless they were recruited as a story event rather than by being defeated.
===Pokémon Ranger series===
In the Pokémon Ranger series, Pokémon are captured with the Capture Styler and are released automatically when they have performed a task such as aiding the player in battle or using their , and can be released from the menu. The player is also forced to release a Pokémon if the player captures a Pokémon and exceeds the limit of Pokémon in their possession.
===Pokémon Rumble series===
In the Pokémon Rumble series, the world consists of Toy Pokémon and they can be released via the menu for money.
===Hey You, Pikachu!===
In the end of the Hey You, Pikachu! storyline, Professor Oak encourages the to release Pikachu back to Viridian Forest. Professor Oak tells the player that Pikachu is a wild Pokémon and would be happiest living with other wild Pokémon.
Once the player uses the PokéHelper to say "Goodbye!", there is a cutscene where Pikachu looks sad to leave at first, but then a group of other Pikachu welcome it back to the forest. Pikachu waves goodbye to the player and leaves.
===Pokémon Sleep===
In Pokémon Sleep, the player can choose to send a Pokémon to Professor Neroli. Pokémon sent to Professor Neroli cannot be taken back, equivalent to releasing the Pokémon in the core series games. When a Pokémon is sent to the Professor, the player will receive for that Pokémon's species, the yield of which varies as follows.
* Unevolved Pokémon: 5 candies
* First evolution of baby Pokémon: 6 candies
* First evolution of non-baby Pokémon: 7 candies
* Second evolution Pokémon: 10 candies 
* Special Pokémon: 25 candies 
==In animation==
===Pokémon the Series===
Throughout , a Trainer releases a Pokémon for several reasons. The Trainer may see it as weak, as Damian did with and Paul with . The Pokémon may have to do something that requires it to leave (such as and his , as well as Ash and his ). Another common reason is that the Pokémon does not listen, frustrating the Trainer, much like when caught . If a Trainer chooses to release their Pokémon, it will be indicated by the Pokémon in question emerging from its Poké Ball in a blue light rather than the usual white light (though this only began occurring in Pokémon the Series: Diamond and Pearl). To guarantee release, some Trainers destroy the Poké Ball, as seen with Jessie and her . As shown in When a House is Not a Home!, Pokémon can even destroy their own Poké Balls.
In , the Ultra Guardians' primary objective is to capture Ultra Beasts that find their way into Alola so they can safely be released and sent back where they came from via Ultra Wormholes.

==Team Plasma==
Team Plasma's ultimate goal has been to convince Trainers to release their Pokémon. In , it is revealed that their leader, Ghetsis, wanted to make himself the only Trainer to own Pokémon in Unova, making him the region's leader almost by default. N, Team Plasma's king, appears frequently to the player to battle them and convince them to release their Pokémon. Each time, he appears with a different team—using the Memory Link in confirms that N released his Pokémon after battles with the player, and the player may encounter and catch them again.
Although there were apparently no other instances of anyone releasing their Pokémon in the games, several Trainers are seen releasing their Pokémon whenever Team Plasma holds a speech in Pokémon Adventures. himself owns a Pokémon (Galvantula) previously owned by another unseen person, and now uses on his team after he decided to keep him after Team Plasma's first seen speech and he agreed to be with him. herself also released her company's , Gigi, although this was against her own will, as it was technically Gigi who left White after she learned about her battle capabilities.
