List of Pokémon by availability

Main article: Game-exclusive Pokémon

Some Pokémon that are only found in one or two games within a particular set, to encourage trading between players. For example, between Pokémon Ruby and Sapphire, Mawile appears only in Ruby, while Sableye appears only in Sapphire. Therefore, a player with Sapphire would not be able to obtain Mawile in-game and could trade with a player of Ruby to obtain one, and vice versa. Game-exclusive Pokémon usually complement each other in design, type, and location in the wild.

Main article: Mutually exclusive Pokémon

In some cases, there are multiple Pokémon potentially available in a single game, but the player must choose one of them or otherwise can't get them all in a single game. They include many trios of starter Pokémon, some Fossil Pokémon and in some cases Legendary Pokémon.

For instance, the player is able to choose between Bulbasaur, Charmander, and Squirtle as their starter in Pokémon Red, Blue, FireRed and LeafGreen. The player may also choose one of these Pokémon as a gift given by Professor Oak in HeartGold, SoulSilver, by Professor Sycamore in X and Y, and by Grand Oak in Pokémon HOME.

Several pairs of games have enough Pokémon to complete their regional Pokédex (such as Pokémon Red and Green, Pokémon Ruby and Sapphire, Pokémon Diamond and Pearl, Pokémon Black 2 and White 2, etc.), except for some event-exclusive Pokémon. However, some games still may need to be restarted at least once to acquire all starters or other mutually exclusive Pokémon.

Main article: Permanently missable Pokémon

Some Pokémon are permanently missable. For instance, prior to Pokémon Platinum, if the player defeats a wild Pokémon that spawned from an in-game event (such as several Legendary Pokémon and other Pokémon visible in the overworld), that Pokémon becomes unavailable in the current game. In this case, no other Pokémon of the same species will appear in the current game.

Main article: Shiny Pokémon

In some cases, a Pokémon cannot be legitimately obtained as Shiny. This can happen if the Pokémon cannot be Shiny in the wild or as an in-game gift (or cannot be obtained this way at all) and has never been distributed as Shiny.

In Generation I, there are 151 Pokémon. 150 Pokémon are available in-game and 1 Pokémon is event-exclusive (Mew).

In Japan, the original pair of releases was Pokémon Red and Green, which were followed by Pokémon Blue. International releases were called Pokémon Red and Blue but followed the availability of the Japanese Red and Green. Pokémon Red and Green together have all the available Pokémon in this generation. It is possible to trade freely with any Generation II game via the Time Capsule, which opens up breeding as an option for obtaining Pokémon.

In Pokémon Yellow, there is a single Pikachu available as the starter Pokémon. This Pikachu, as well as all other Pikachu in Pokémon Yellow, cannot evolve in the game where it was caught. However, it can evolve normally if traded to another game, and conversely, a Pikachu from another game can evolve normally in Yellow. Due to this, Raichu is unavailable in Pokémon Yellow outside of trades.

In Generation II, there are 251 Pokémon.

• In the original Game Boy Color release, 249 Pokémon are available in-game and 2 Pokémon are event-exclusive (Mew and Celebi).
• In the Virtual Console release, 250 Pokémon are available in-game (now including Celebi) and 1 is event-exclusive (Mew). Prior to Pokémon Crystal's Virtual Console release, Celebi was still event-exclusive.

In the Japanese version of Pokémon Crystal for Game Boy Color, the player is able to summon a wild Celebi if they have the GS Ball that was distributed via the Mobile System GB, which was shut down in 2002. In this generation, Celebi was also distributed in other countries, by other means unrelated to the GS Ball. This changed in the Virtual Console release, where the GS Ball is found in-game (in all languages).

Pokémon Gold and Silver together have all the non-event Pokémon from both Generations I and II, except for these Generation I Pokémon and their evolutions: Bulbasaur, Charmander, Squirtle, Omanyte, Kabuto, Articuno, Zapdos, Moltres, and Mewtwo. Pokémon Crystal is missing some Pokémon that can be found in either Gold or Silver. Additionally, all Generation I Pokémon can be traded from the Generation I games via the Time Capsule.

In Generation III, there are 386 Pokémon.

In the core series, 380 Pokémon are available in-game and 6 Pokémon are event-exclusive (Mew, Ho-Oh, Lugia, Celebi, Jirachi, and Deoxys). Additionally, Ho-Oh and Lugia can be caught in the games Pokémon Colosseum and XD, respectively, and traded to the core series games. Jirachi can be obtained from Pokémon Channel in Europe or from the Pokémon Colosseum Bonus Disc in America, while Celebi can be obtained from the Pokémon Colosseum Bonus Disc in Japan.

There is no way to transfer Pokémon from previous generations into Generation III. However, all Pokémon from previous generations are available in the Generation III games by other means. Ho-Oh and Lugia are the only two Pokémon that were normally available in the Generation II games but cannot be found in Generation III games outside of events and trades with Colosseum or XD.

Pokémon Ruby and Sapphire together have all the Pokémon from the Generation III Hoenn Pokédex, except for the event-exclusive Jirachi and Deoxys. Pokémon Emerald is missing some Pokémon from the Hoenn Pokédex that can be found in either Ruby or Sapphire. Wild Surskit can only appear in Emerald in a mass outbreak after record mixing with Ruby or Sapphire. Pokémon FireRed and LeafGreen together have all the Pokémon from the Generation III Kanto Pokédex, except for the event-exclusive Mew.

Pokémon outside of the Hoenn Pokédex can only be obtained in Ruby and Sapphire by trading with other games. Most of the Pokémon absent from both the Kanto and Hoenn Pokédexes (which are all Generation II Pokémon in these games) are available either in the Sevii Islands from FireRed and LeafGreen or in the Safari Zone from Emerald. In the case of the Johto starter Pokémon, the player can receive one of their choice in Emerald after obtaining all non-event Pokémon in the Hoenn Pokédex.

Espeon and Umbreon are special cases in that, not counting Colosseum or XD, they require a trade to be obtained, but do not evolve by trading. The real-time clock required for the evolution is present only in Hoenn-based games, but Eevee cannot be obtained in these games without trading it from other games.

The form of Deoxys depends on which game it is in: it is in Normal Forme in Ruby, Sapphire, Colosseum, and XD, Attack Forme in FireRed, Defense Forme in LeafGreen, and Speed Forme in Emerald. Its form cannot be changed without trading.

The Mew found on the Faraway Island can only be accessed with the Old Sea Map, an event-exclusive item which was only legitimately distributed in Japan. However, Mew was also distributed in some other events elsewhere unrelated to the Old Sea Map and the Faraway Island.

The Nintendo DS is backwards-compatible with the Game Boy Advance games, except without any multiplayer features. Therefore, when a player uses a Nintendo DS to play the Generation III games, they are not able to trade Pokémon or connect with a Nintendo GameCube.

In Generation IV, there are 493 Pokémon.

In the core series, 484 Pokémon are available in-game and 9 Pokémon are event-exclusive (Mew, Celebi, Jirachi, Deoxys, Phione, Manaphy, Darkrai, Shaymin, and Arceus). Prior to the release of Pokémon HeartGold and SoulSilver, Lugia and Ho-Oh were also event-exclusive. Additionally, a Manaphy Egg may be transferred from any of the 3 Pokémon Ranger games, and Phione may be bred from Manaphy.

Pokémon from the Generation III games may be transferred to Generation IV via the Pal Park.

Aside from Regirock, Regice, Registeel, and Regigigas, all non-event Pokémon from Generations I–IV are available in the Generation IV games and don't require the Pal Park. A Regigigas may be caught in Diamond, Pearl, and Platinum if the player already has Regirock, Regice, and Registeel. Conversely, Regirock, Regice, and Registeel may be caught in Platinum if the player already has a fateful encounter Regigigas. The only way to obtain these Pokémon without events is to transfer the trio of Legendary titans from the Generation III games via the Pal Park and use them to obtain Regigigas.

Pokémon Diamond and Pearl together have all the Pokémon from the Sinnoh Pokédex (which has 150 Pokémon in these games), aside from the event-exclusive Manaphy. Pokémon Platinum is missing some Pokémon from the Sinnoh Pokédex (which has 210 Pokémon in this game) that can be found in either Diamond or Pearl. Pokémon HeartGold and SoulSilver together have all the Pokémon from the Generation IV Johto Pokédex (which has 256 Pokémon in this generation), except for the event-exclusive Celebi and Mew. Alternatively, all Pokémon from the Johto Pokédex may be transferred from the Generation III games, except for 5 new evolutions introduced in Generation IV.

The dual-slot mode causes some additional wild Pokémon to appear in Diamond, Pearl, and Platinum if a Game Boy Advance cartridge is inserted in the Nintendo DS system. This is not possible on the Nintendo DSi and Nintendo 3DS systems, which lack a GBA slot. However, all Pokémon available from the dual-slot mode are also available (without the dual-slot mode) in HeartGold or SoulSilver.

Spiritomb may be caught in the Hallowed Tower in Diamond, Pearl, and Platinum, but only after the player speaks with other players in the Underground at least 32 times. They are actual people (as opposed to NPCs) playing the game and connected via the wireless features of the Nintendo DS. In this generation, the Pokéwalker is the only other place where Spiritomb is available.

Origin Forme Giratina, Sky Forme Shaymin, and all appliance forms of Rotom were introduced in Platinum and are also compatible with HeartGold and SoulSilver, but they are incompatible with Diamond and Pearl.

Spiky-eared Pichu is event-exclusive. The Pikachu-colored Pichu was a Shiny Pichu distributed via events in Diamond, Pearl, and Platinum, but if it is traded with HeartGold or SoulSilver and taken to Ilex Forest, then the player will obtain Spiky-eared Pichu. This can still occur even if Pikachu-colored Pichu evolves. The Spiky-eared Pichu is only available in HeartGold and SoulSilver and is unable to be traded or transferred to any other games. Only one Spiky-eared Pichu is available per game in HeartGold and SoulSilver.

Some Pokémon can be found through the Pokéwalker, a pedometer device that was shipped with and is able to communicate with HeartGold and SoulSilver. Some Pokémon obtained from the Pokéwalker cannot be found normally in HeartGold and SoulSilver (such as Castform, Feebas, and Wailmer). However, all Pokémon from the Pokéwalker may be normally found in multiple Generation IV games (the ones unavailable from HeartGold and SoulSilver may be found in Diamond, Pearl, or Platinum), so the Pokéwalker is not required to find any Pokémon in this generation.

Rayquaza can be caught in the Embedded Tower in HeartGold and SoulSilver, but only after the player trades with the opposite version to obtain a Kyogre or Groudon.

In Generation V, there are 649 Pokémon.

In the core series, 636 Pokémon are available in-game and 13 Pokémon are event-exclusive (Mew, Celebi, Jirachi, Deoxys, Phione, Manaphy, Darkrai, Shaymin, Arceus, Victini, Keldeo, Meloetta, and Genesect). Prior to the release of Pokémon Black 2 and White 2, Zorua and Zoroark were also event-exclusive.

Pokémon from Generation IV may be transferred to Generation V via Poké Transfer (including any Pokémon previously transferred from Generation III). Some Pokémon were also available from the now-defunct Dream World.

All non-event Pokémon that cannot be obtained in Generation V without Poké Transfer may be found in Generation IV (since Generation IV includes almost all of the non-event Pokémon from the previous generations). Some Pokémon available in the Dream World are not available anywhere else in Generation V (such as Ekans and Diglett), but may be transferred from Generation IV as well.

Pokémon Black and White together, as well as Pokémon Black 2 and White 2 together, have all the non-event Pokémon from the Unova Pokédex (which has 156 Pokémon in the first pair of games, and was expanded to 301 Pokémon in the second pair of games).

In Black and White, the Relocator may be used to transfer certain event Pokémon from the Generation IV games for the purpose of catching Zorua and Zoroark. Zorua becomes available if the player transfers Celebi, and Zoroark becomes available if the player transfers the Shiny Legendary beasts (Raikou, Entei, and Suicune).

Landorus can be caught at the Abundant Shrine in both Black and White after the player trades with the opposite version to obtain Tornadus or Thundurus.

White Kyurem, Black Kyurem, the Therian Forms of the Forces of Nature (Tornadus, Thundurus, and Landorus), and Resolute Form Keldeo were introduced in Black 2 and White 2, and are incompatible with Black and White. Additionally, all of these forms except for Keldeo's cannot be traded at all; due to this and the way that the DNA Splicers work, it is impossible to own both White Kyurem and Black Kyurem at the same time, and it is also impossible to own more than one Black Kyurem or more than one White Kyurem at once.

In Black 2 and White 2, Regirock, Regice and Registeel can be caught in the Underground Ruins. However, Regice only appears in Black 2 if the player receives the Iceberg Key from White 2 via Unova Link, while Registeel only appears in White 2 if the player receives the Iron Key from Black 2 via Unova Link. Regigigas can then be caught in Twist Mountain only if the player has Regirock, Regice and Registeel, so Regigigas also requires trading or using Unova Link to obtain without using Poké Transfer.

Stunky and Glameow are available via a special Funfest Mission that can only be hosted in Black 2 or White 2, respectively. However, the opposite version can still obtain the other Pokémon by joining the Funfest Mission.

Certain Pokémon that can be caught in Black 2 and White 2 are found only in the Nature Preserve, which is only accessible by seeing all non-event Pokémon in the New Unova Pokédex (most notably, Magikarp and Gyarados, otherwise available only by purchasing a Magikarp from the Magikarp salesman, are available to catch at the Nature Preserve). Accessing the Nature Preserve requires trading, as it is impossible to see all stages of whichever starter was not picked by the player nor by Hugh, as well as some of the version-exclusive Pokémon not being used by any NPC Trainers.

In Generation VI, there are 721 Pokémon.

In the core series, 706 Pokémon are available in-game and 15 Pokémon are event-exclusive (Mew, Celebi, Jirachi, Phione, Manaphy, Darkrai, Shaymin, Arceus, Victini, Keldeo, Meloetta, Genesect, Diancie, Hoopa, and Volcanion). Prior to the release of Pokémon Omega Ruby and Alpha Sapphire, Deoxys was also event-exclusive.

Pokémon from Generation V may be transferred to Pokémon Bank via the Poké Transporter (including any Pokémon previously transferred from Generations III and IV). Once in Pokémon Bank, these Pokémon can be withdrawn to the Generation VI games. However, Pokémon that have been in a Generation VII game and Pokémon sent from the Virtual Console releases of the Generation I and II games cannot be withdrawn to Generation VI.

All non-event Pokémon from Generations I–VI may be found in Generation VI without requiring use of Pokémon Bank. However, in the Generation VI games, Deerling and Sawsbuck may only be found in their Spring Form. Other forms can only be obtained by transferring them from the Generation V games.

Pokémon X and Y together have all the non-event Pokémon from the three Kalos Pokédexes (which have a total of 457 Pokémon; most are from previous generations, though all Generation VI Pokémon are found in the Kalos Pokédexes). Pokémon Omega Ruby and Alpha Sapphire together have all the non-event Pokémon from the Generation VI Hoenn Pokédex (which has 211 Pokémon; all of them are from previous generations).

In Pokémon X and Y, several Pokémon are available from the Friend Safari, which contains various areas that are unlocked based on the friends registered on the player's Nintendo 3DS. However, there is no Pokémon available exclusively in the Friend Safari, so it is not required to catch any Pokémon.

In Pokémon Omega Ruby and Alpha Sapphire, several Pokémon can be found in the Mirage spots, which may appear and disappear and are accessible by soaring in the sky. Some Mirage spots contain a Legendary Pokémon from a previous generation, and appear if the player meets a certain condition (such as having certain Pokémon in their party, or having any level 100 Pokémon in their party). There are also 32 daily Mirage spots that contain multiple non-Legendary Pokémon. Only one daily Mirage spot appears on each day, unless the player receives additional Mirage spots via StreetPass.

The Pokémon below (and their evolutionary families, via evolution or breeding) can be found in the daily Mirage spots, and some of them can be found in the Friend Safari as well. However, they cannot be found anywhere else in the Generation VI games (aside from events and transfers from previous generations) and therefore may not be available until the player waits for the correct day, receives the correct Mirage spot via StreetPass, or unlocks the correct area in the Friend Safari.

Available only in the daily Mirage spots and the Friend Safari:

• Venomoth
• Chansey (Friend Safari), Happiny (Mirage spots)
• Tangela
• Electabuzz (Friend Safari), Elekid (Mirage spots)

Some Mega Evolutions, Primal Reversion, the Cosplay Pikachu, and Hoopa Unbound were introduced in Pokémon Omega Ruby and Alpha Sapphire, and are incompatible with Pokémon X and Y. The Cosplay Pikachu is only available in Omega Ruby and Alpha Sapphire and is unable to be traded or transferred to any other games. Only one Cosplay Pikachu is available per game in Omega Ruby and Alpha Sapphire.

In Generation VII, there are 809 Pokémon. Prior to Let's Go, Pikachu! and Let's Go, Eevee!, there were 807 Pokémon. Prior to Pokémon Ultra Sun and Ultra Moon, there were 802 Pokémon. There are also 18 Alolan Forms available in all games of this generation.

• In Pokémon Sun and Moon, 786 Pokémon are available in-game and 16 Pokémon are event-exclusive (Mew, Jirachi, Phione, Manaphy, Darkrai, Shaymin, Arceus, Victini, Keldeo, Meloetta, Genesect, Diancie, Hoopa, Volcanion, Magearna, and Marshadow).
• In Pokémon Ultra Sun and Ultra Moon, 790 Pokémon are available in-game (the same as in Sun and Moon, with the additions of Poipole, Naganadel, Stakataka, and Blacephalon) and 17 Pokémon are event-exclusive (the same as in Sun and Moon, with the addition of Zeraora).
  • Prior to the Virtual Console release of Pokémon Crystal, Celebi was also event-exclusive in Pokémon Sun, Moon, Ultra Sun, and Ultra Moon.
• In Let's Go, Pikachu! and Let's Go, Eevee!, the first 150 Pokémon from the Kanto Pokédex are available in-game (including their Alolan Forms), and 3 additional Pokémon are available by other means: Mew by getting it from the Poké Ball Plus and Meltan and Melmetal by transferring them from Pokémon GO via the GO Park. This pair of games is incompatible with all other Pokémon.

Pokémon from the Generation VI and VII Nintendo 3DS games may be deposited directly into Pokémon Bank. Pokémon from the Virtual Console releases of the Generation I and II games, as well as Pokémon from the Generation V games, may be transferred to Pokémon Bank via the Poké Transporter (including any Pokémon previously transferred from Generations III and IV). Once in Pokémon Bank, these Pokémon can be withdrawn to the Generation VII 3DS games.

Many Pokémon from previous generations cannot be found in Sun, Moon, Ultra Sun, and Ultra Moon, but may be transferred from earlier games. Besides Celebi, all non-event Pokémon missing in Generation VII can be found in Generation VI. However, Deerling and Sawsbuck can only be found in their Spring Forms in Generation VI; other forms can only be obtained by transferring them from Generation V. Celebi can be obtained without events by transferring it from the Virtual Console release of Pokémon Crystal.

Sun and Moon together, as well as Ultra Sun and Ultra Moon together, have all the non-event Pokémon from the Alola Pokédex (which has 302 Pokémon in the first pair of games and was expanded to 403 Pokémon in the second pair of games).

All Pokémon introduced in Ultra Sun and Ultra Moon are incompatible with Sun and Moon. Meltan and Melmetal are incompatible with Sun, Moon, Ultra Sun, and Ultra Moon. The Dusk Mane, Dawn Wings and Ultra forms of Necrozma, as well as the event-only Partner Cap Pikachu and Dusk Form Lycanroc, were introduced in Ultra Sun and Ultra Moon, and are not compatible with Sun and Moon.

The Partner Pikachu and Eevee are exclusive to Let's Go, Pikachu! and Eevee!, respectively. Each game has only one Partner Pikachu or Eevee; it cannot evolve, and it cannot be traded or transferred to other games. However, other (non-Partner) Pikachu and Eevee are available in both games.

In Generation VIII, there are 905 Pokémon. When Pokémon Sword and Shield were initially released, there were 890 Pokémon; 3 more debuted in The Isle of Armor, including the event-exclusive Zarude, 5 more debuted in The Crown Tundra, and the remaining 7 debuted in Pokémon Legends: Arceus.

No games in this generation feature every Pokémon. Pokémon HOME, an application for storing and transferring Pokémon, is compatible with the first 898 Pokémon; however, the games themselves are incompatible with certain Pokémon. These incompatible Pokémon cannot be obtained in the games in any way, including via transfer.

Pokémon in Pokémon Bank, including those transferred from previous generations, can be transferred to Pokémon HOME. Pokémon from Pokémon: Let's Go, Pikachu! and Let's Go, Eevee! can also be deposited into Pokémon HOME, and since November 10, 2020, it has been possible for Pokémon from Pokémon GO to be transferred into Pokémon HOME via the GO Transporter. Additionally, some Pokémon have been directly distributed in Pokémon HOME, either as events or rewards for certain actions; most notably, the Original Color Magearna is obtainable in HOME as a reward for completion of the National Pokédex, which is the only way to obtain it, though it can only be obtained with events due to the fact that some of the Pokémon in the National Pokédex are event-exclusive. Once in HOME, if a Pokémon is compatible with Pokémon Sword and Shield, it can be withdrawn normally to these games; however, if a Legendary or Mythical Pokémon (besides Meltan or Melmetal) is transferred to HOME from Pokémon GO, then it cannot be deposited into Sword or Shield unless the player has already obtained one of its species in those games. Pokémon Brilliant Diamond and Shining Pearl and Pokémon Legends: Arceus are set to also receive Pokémon HOME compatibility at some point in 2022.

Pokémon Sword and Shield are compatible with 664 Pokémon. Of these, 654 are available in-game and 10 are event-exclusive (Mew, Jirachi, Victini, Genesect, Diancie, Volcanion, Magearna, Marshadow, Zeraora, and Zarude). Prior to the release of The Crown Tundra, Keldeo was also event-exclusive.

• At first, only 401 Pokémon were obtainable, consisting of the 400 Pokémon from the Galar Pokédex and Mew from the Poké Ball Plus. Sword and Shield together have all 400 Pokémon in the Galar Pokédex.
• In version 1.1.0 of the games, Galarian Slowpoke was added and made available to catch at Wedgehurst Station, increasing the total number of obtainable Pokémon to 402.
• Upon the release of Pokémon HOME, 34 additional Pokémon were made available via transfer from previous generations (including the event-exclusive Jirachi, Keldeo, Marshadow, and Zeraora), bringing the total number of obtainable Pokémon to 436.
• In version 1.2.0 of the games, with the release of The Isle of Armor, 103 additional Pokémon (including the event-exclusive Zarude) not present in the Galar Pokédex became available as part of a new Isle of Armor Pokédex, and Magearna was made available via Pokémon HOME (albeit as an event-exclusive Pokémon), bringing the total number of obtainable Pokémon to 540. Additionally, 15 Pokémon that were previously exclusive to transfer from previous generations were made available through other means. With The Isle of Armor, Sword and Shield together have all 211 Pokémon from the Isle of Armor Pokédex except for the event-exclusive Zarude, and also have Rowlet, Litten, Popplio, and their evolutionary families.
• In version 1.3.0 of the games, with the release of The Crown Tundra, 124 additional Pokémon (including the event-exclusive Victini, Genesect, Diancie, and Volcanion) present in neither the Galar Pokédex nor the Isle of Armor Pokédex became obtainable, bringing the total to 664. Of these newly available Pokémon, 71 became available as part of a new Crown Tundra Pokédex. Additionally, 13 Pokémon that were previously exclusive to transfer from previous generations were made available through other means (including Keldeo, thus making it no longer event-exclusive). With The Crown Tundra, Sword and Shield together have all 210 Pokémon in the Crown Tundra Pokédex, as well as 59 others.

In total, Pokémon Sword and Shield together, including the Pokémon Sword and Shield Expansion Pass, have 651 Pokémon, consisting of all of the Pokémon in the Galar, Isle of Armor, and Crown Tundra Pokédexes, besides the event-exclusive Zarude, and 68 others not in any of the three Pokédexes. The games are also compatible with 13 additional Pokémon (all of which are Mythical Pokémon) that are only obtainable via events or transferring them from previous generations: Mew (which is also available via the Poké Ball Plus), Celebi, Jirachi, Victini, Genesect, Diancie, Volcanion, Magearna, Marshadow, Zeraora, Meltan, Melmetal, and Zarude (which is the only one of the 13 not obtainable via transfer from a previous generation). All of these except Celebi, Meltan and Melmetal are event-exclusive, and none of them are in any of the three Pokédexes in the games except Zarude, which is in the Isle of Armor Pokédex.

Pokémon Sword and Shield are also compatible with Galarian Forms and Alolan Forms. They feature all 19 Galarian Forms, but due to some Pokémon with Alolan Forms not being featured in the games, only 11 out of the 18 Alolan Forms are present. All Alolan Forms (that exist in the games) and original forms of Pokémon with Galarian Forms are obtainable without requiring transfer from previous generations, though most require the Expansion Pass to obtain in this way.

• At first, 13 Galarian Forms and no Alolan Forms were available. Additionally, the original forms of Meowth, Yamask, and Mr. Mime are obtainable via in-game trades.
• Galarian Slowpoke was added and made available to catch at Wedgehurst Station in the version 1.1.0 update. However, it was initially unable to evolve.
• Upon the release of Pokémon HOME, the Alolan Forms of Raichu, Vulpix, Ninetales, Diglett, Dugtrio, Meowth, and Persian became available via transfer from previous games. Additionally, the original forms of all Pokémon with Galarian Forms became available via transfer as well, with the exception of Slowpoke, which was unable to be transferred.
• With the release of The Isle of Armor, due to the additions of Sandshrew, Sandslash, Exeggutor, and Marowak, the Alolan Forms of each have become available via transfer. Additionally, Slowpoke's original form was made available to transfer, as well as the rest of the Slowpoke line, and Galarian Slowpoke was made available to catch outside of Wedgehurst Station. Galarian Slowbro was also added, with Galarian Slowpoke now being able to evolve into it.
  • The Isle of Armor also introduces an NPC named Regina, who appears in random locations on the Isle of Armor and will trade Alolan Forms to the player in exchange for their original forms, or will trade the original forms of Pokémon in exchange for their Galarian Forms. After she has been traded with, she will relocate to another position on the island and be available for another trade; it is possible for her to repeat the same trade an indefinite number of times. From Regina, the original forms of Meowth, Ponyta, Farfetch'd, Weezing, Mr. Mime, Corsola, Zigzagoon, Darumaka, and Stunfisk and the Alolan Forms of Exeggutor and Marowak can be obtained without requiring transfer (as can the original forms of Rapidash, Linoone, and Darmanitan via evolution). However, trades for Farfetch'd and Darumaka are exclusive to Pokémon Sword, while trades for Ponyta and Corsola are exclusive to Pokémon Shield.
  • The Isle of Armor also features a Diglett Trainer who owns 151 Alolan Diglett that are scattered throughout the island. The player is tasked with finding these Diglett, and the Trainer will reward them with Pokémon, most of which are Alolan Forms, when they reach certain milestones. From this Diglett Trainer, the following forms of Pokémon are obtainable without requiring transfer: Alolan Meowth (after finding 5 Diglett), regular Slowpoke (after finding 10 Diglett), Alolan Vulpix (after finding 20 Diglett), Alolan Sandshrew (after finding 30 Diglett), Alolan Raichu (after finding 40 Diglett), Alolan Marowak (after finding 50 Diglett), Alolan Exeggutor (after finding 75 Diglett), and Alolan Diglett (after finding all 151 Diglett). By evolving these Pokémon, the Alolan Forms of Persian, Ninetales, Sandslash and Dugtrio and the original forms of Slowbro and Slowking are also obtainable.
• With the release of The Crown Tundra, the Galarian Forms of Articuno, Zapdos, and Moltres became available, as did their original forms via transfer. However, it is also possible to obtain the original forms of Articuno, Zapdos and Moltres without having to transfer them, as they are among the available Legendary Pokémon in Dynamax Adventures. Galarian Slowking was also added, with Galarian Slowpoke now being able to evolve into it.

Pokémon Brilliant Diamond and Shining Pearl are compatible with 493 Pokémon, consisting of every Pokémon from the first four generations, like in the original Pokémon Diamond and Pearl.

• 484 Pokémon are available in-game, 4 Pokémon are event-exclusive (Mew, Jirachi, Phione, and Manaphy), while the remaining 5 (Celebi, Deoxys, Darkrai, Shaymin, and Arceus) are not currently legitimately obtainable.
  • In order to obtain Mew, the player must have save data for Pokémon Let's Go, Pikachu! or Pokémon Let's Go, Eevee! on their Nintendo Switch system and then talk to the Gentleman in Floaroma Town to receive it.
  • In order to obtain Jirachi, the player must have save data for Pokémon Sword or Pokémon Shield on their Nintendo Switch system and then talk to the Madame in Floaroma Town to receive it.
  • A Manaphy Egg was distributed through Mystery Gift via the Internet from November 19, 2021 to February 21, 2022. This egg could hatch into Manaphy which could be bred to produce Phione.

Pokémon Legends: Arceus is compatible with 242 Pokémon. All Pokémon that debuted in Pokémon Diamond and Pearl are compatible.

• The first 240 Pokémon from the Hisui Pokédex are available in-game, while the other 2 Pokémon (Darkrai and Shaymin) are event-exclusive.
  • In order to obtain Darkrai the player must have save data for Pokémon Brilliant Diamond or Pokémon Shining Pearl on their Nintendo Switch system, seen the game's end credits, and then receive the research quest "The Darksome Nightmare."
  • In order to obtain Shaymin the player must have save data for Pokémon Sword or Pokémon Shield on their Nintendo Switch system, seen the game's end credits, and then receive the research quest "A Token of Gratitude."
