View source for Pokémon availability

'''Pokémon availability''' refers to the various means of obtaining {{OBP|Pokémon|species}} in the {{pkmn|games}}.

==Overview==
In all [[core series]] games, some Pokémon may be {{pkmn2|caught}} and others are available via [[evolution]]. There are various [[methods of evolution]], including by reaching a certain [[level]], using an [[evolution stone]], or when the Pokémon is [[trade]]d. Other methods to obtain Pokémon also exist, including [[breeding]], [[in-game trade]]s, receiving them as [[gift Pokémon]], and {{pkmn2|event}}s. Some Pokémon may not be available in a certain game, but may be [[trade]]d from another game, or [[transfer]]red from an earlier [[generation]].

From [[Generation I]] until {{g|Ultra Sun and Ultra Moon}}, each core series game was compatible with all the Pokémon species released to date, either from the current game itself or from the available trades, transfers, and events. In [[Generation III]], although it was initially impossible to legitimately collect all existing Pokémon due to the lack of connection with previous generations, those missing Pokémon eventually became available with new games in the same generation. However, from {{LGPE}} onwards, each new core series game has a limited pool of available Pokémon.

===Starter Pokémon===
{{main|Starter Pokémon}}
The [[starter Pokémon]] is given to the player at the start of their [[Pokémon journey]]. In most core series {{pkmn|games}} (except in {{game|Yellow}} and {{LGPE}}), the player can choose a {{t|Fire}}-, {{t|Water}}-, or {{type|Grass}} starter Pokémon at [[level]] 5. At least one of the player's [[rival]]s will also always choose or have a starter Pokémon, which may either have a type advantage or disadvantage over the player's depending on the game.

===Wild Pokémon===
{{main|Wild Pokémon}}
The player is able to find and {{pkmn|battle}} several kinds of [[wild Pokémon]] in [[tall grass]], [[cave]]s, [[water]], etc. The wild Pokémon can be caught using a [[Poké Ball]].

===Version-exclusive Pokémon===
{{main|Version-exclusive Pokémon}}
Some Pokémon are only found in one or two games within a particular set, to encourage [[Trade|trading]] between players. For example, between {{game|Ruby and Sapphire|s}}, {{p|Mawile}} appears only in Ruby, while {{p|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. Version-exclusive Pokémon usually complement each other in design, type, and location in the wild.

===Mutually exclusive Pokémon===
{{main|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 {{p|Bulbasaur}}, {{p|Charmander}}, and {{p|Squirtle}} as their {{pkmn2|starter}} in {{game|Red and Blue|s|Pokémon Red, Blue}}, {{game|FireRed and LeafGreen|s|FireRed and LeafGreen}}. The player may also choose one of these Pokémon as a gift given by [[Professor Oak]] in {{game|HeartGold and SoulSilver|s|HeartGold, SoulSilver}}, by [[Professor Sycamore]] in {{g|X and Y}}, and by [[Grand Oak]] in {{g|HOME}}.

Several pairs of games have enough Pokémon to complete their [[regional Pokédex]], 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.

===Permanently missable Pokémon===
{{main|Permanently missable Pokémon}}

Some Pokémon are permanently missable. For instance, prior to {{game|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.

===Unobtainable Shiny Pokémon===
{{main|List of unobtainable 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.

==Availability by generation==
:''See also: [[List of Pokémon by availability]]''

===Generation I===
In [[Generation I]], there are 151 Pokémon. 150 Pokémon are available in-game and 1 Pokémon is event-exclusive ({{p|Mew}}).

{{p|Lickitung}}, {{p|Jynx}}, {{p|Farfetch'd}}, and {{p|Mr. Mime}} were originally exclusive to [[in-game trade]]s. For this reason, until the release of later games in which they could be obtained in the wild, they could only have their traded nicknames and the Original Trainer of "TRAINER".

In this generation, the [[Pokédex]] location map does not display the Pokémon available in the [[Cerulean Cave]]. For instance, the Pokédex map claims that the location of wild {{p|Rhydon}} is unknown in {{game|Red and Blue|s}}, when in fact wild Rhydon is only found in the Cerulean Cave.

It is possible to trade Pokémon with the [[Generation II]] games via the [[Time Capsule]], which opens up {{pkmn|breeding}} as an option for obtaining Pokémon.

====Pokémon Red and Blue====
In Japan, the original pair of releases was {{game|Red and Green|s}}, which were followed by {{jpn|Pokémon Blue Version|Pokémon Blue}}. International releases were called {{game|Red and Blue|s}} but followed the availability of the Japanese Red and Green. {{game|Red and Green|s}} together have all the available Pokémon in this generation.

====Pokémon Yellow====
In {{game|Yellow}}, there is {{ga|Red's Pikachu|a single Pikachu}} available as the [[starter Pokémon]]. This {{p|Pikachu}} 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, {{p|Raichu}} is unavailable in Pokémon Yellow outside of trades.

===Generation II===
In [[Generation II]], there are 251 Pokémon.

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

It is possible to trade Pokémon between Generation I and II games via the [[Time Capsule]]. These Pokémon and their evolutions (if any) are available in the [[Generation I]] games, but cannot be found in [[Generation II]] outside of trades: {{p|Bulbasaur}}, {{p|Charmander}}, {{p|Squirtle}}, {{p|Omanyte}}, {{p|Kabuto}}, {{p|Articuno}}, {{p|Zapdos}}, {{p|Moltres}}, and {{p|Mewtwo}}.

====Pokémon Gold and Silver====
In {{game|Gold and Silver|s}}, almost all Generation II Pokémon are available without trades (except for trade evolutions) or events, other than {{p|Celebi}}.

====Pokémon Crystal====
In {{game|Crystal}}, most Generation I and II Pokémon are available except for some version-exclusive Pokémon.

In the Japanese version of {{game|Crystal}} for Game Boy Color, the player is able to summon a wild {{p|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 {{gdis|List of European language event Pokémon distributions|II|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).

===Generation III===
In [[Generation III]], there are 386 Pokémon. 380 Pokémon are available in the [[core series]] games, and 6 Pokémon are available by other means ({{p|Mew}}, {{p|Ho-Oh}}, {{p|Lugia}}, {{p|Celebi}}, {{p|Jirachi}}, and {{p|Deoxys}}).

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 as well.

It is possible to trade Pokémon between the core series games and the [[Orre]]-based side series games for the [[Nintendo GameCube]] ({{g|Colosseum}} and {{XD}}). However, completing the [[National Pokédex]] in the core series does not require the Orre games. Almost all Pokémon found in the Orre games are also obtainable without events in the core series. Ho-Oh and Lugia are the only two exceptions, which can be obtained in the core series via the [[MysticTicket]] event or traded from the Orre games, but those two Pokémon are not required for the National Pokédex in this generation.

{{p|Espeon}} and {{p|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 [[Time|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 {{p|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.

{{p|Unown}}'s ? and ! forms were originally introduced in the data of Pokémon Ruby and Sapphire, but they were not originally found anywhere at the time of release of these games and {{pkmn|Colosseum}}. Those forms were later made available in Pokémon FireRed and LeafGreen.

In Pokémon FireRed, LeafGreen, and Emerald, a planned [[Mystery Gift]] event would allow some [[Generation II]] Pokémon to appear in the [[Altering Cave]] ({{p|Mareep}}, {{p|Aipom}}, {{p|Pineco}}, {{p|Shuckle}}, {{p|Teddiursa}}, {{p|Houndour}}, {{p|Stantler}}, and {{p|Smeargle}}), but this event was never released. Some of these Pokémon can be found in Colosseum or XD, and they all became available elsewhere in Emerald as well.

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 the GameCube.

====Pokémon Ruby, Sapphire, and Emerald====
In {{game|Ruby and Sapphire|s}}, the first 200 Pokémon from the {{gdis|List of Pokémon by Hoenn Pokédex number|III|Generation III Hoenn Pokédex}} are available in-game (not counting the event-exclusive {{p|Jirachi}} and {{p|Deoxys}}). Other than trades or events, there are no available Pokémon outside the Hoenn Pokédex.

In {{game|Emerald}}, most Pokémon from Ruby and Sapphire are available as well (except some [[version-exclusive Pokémon]]). After the [[National Pokédex]] is obtained, there are also 33 [[Generation II]] Pokémon (almost all found in the {{ho|Safari Zone}}). Those Generation II Pokémon are not otherwise obtainable in the core series games, although some of them can be traded from the Orre-based side series games.

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. Wild {{p|Surskit}} can only appear in Emerald in a [[mass outbreak]] after [[record mixing]] with Ruby or Sapphire.

====Pokémon FireRed and LeafGreen====
In {{game|FireRed and LeafGreen|s}}, there are 195 Pokémon available in-game. This includes the first 150 Pokémon from the [[List of Pokémon by Kanto Pokédex number|Generation III Kanto Pokédex]] (not counting the event-exclusive {{p|Mew}}). The other Pokémon become available after the [[National Pokédex]] is obtained: 43 [[Generation II]] Pokémon (almost all found in the [[Sevii Islands]]), and 2 [[Generation III]] Pokémon ({{p|Azurill}} and {{p|Wynaut}}).

The {{p|Mew}} found on the [[Faraway Island]] can only be accessed with the [[Old Sea Map]], an event-exclusive item which {{DL|List of other event distributions in Generation III|Old Sea Map|was only legitimately distributed in Japan and Taiwan}}. However, Mew {{gdis|List of English event Pokémon distributions|III|was also distributed in some other events elsewhere}} unrelated to the Old Sea Map and the Faraway Island.

====Pokémon Channel, Colosseum, and XD: Gale of Darkness====
In {{g|Colosseum}}, there are 60 obtainable Pokémon outside of trades: 2 [[starter Pokémon]] ({{p|Espeon}} and {{p|Umbreon}}), [[List of Shadow Pokémon|51 Shadow Pokémon]], 6 evolutions of Shadow Pokémon, and the {{p|Ho-Oh}} from [[Mt. Battle]]. However, the 3 Shadow Pokémon found in the [[Card e Room]] ({{p|Togepi}}, {{p|Mareep}}, and {{p|Scizor}}) are exclusive to the Japanese version, bringing down the total to 57 obtainable Pokémon in the international versions.

In {{g|XD: Gale of Darkness}}, there are 130 obtainable Pokémon outside of trades: the single [[starter Pokémon]] ({{p|Eevee}}), 1 [[Eeveelution]] (out of 5 [[Mutually exclusive Pokémon#Pokémon XD: Gale of Darkness|mutually exclusive]] options), [[List of Shadow Pokémon|83 Shadow Pokémon]], 36 evolutions of Shadow Pokémon, the 3 [[Johto]] [[starter Pokémon]] from [[Mt. Battle]], and the 6 evolutions of Johto starter Pokémon.

{{p|Ho-Oh}} can be obtained from [[Mt. Battle]] in {{g|Colosseum}} and {{p|Lugia}} can be caught in {{g|XD: Gale of Darkness}}. Jirachi can be obtained from {{g|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.

===Generation IV===
In [[Generation IV]], there are 493 Pokémon.

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

Pokémon from the Generation III games may be [[transfer]]red to Generation IV via the [[Pal Park]].

Aside from {{p|Regirock}}, {{p|Regice}}, {{p|Registeel}}, and {{p|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 giants]] from the Generation III games via the Pal Park and use them to obtain Regigigas.

====Pokémon Diamond, Pearl, and Platinum====
{{game|Diamond and Pearl|s}} together have all the Pokémon from the [[List of Pokémon by Sinnoh Pokédex number|Sinnoh Pokédex]] (which has 150 Pokémon in these games), aside from the event-exclusive {{p|Manaphy}}. {{game|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.

{{p|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 need to be connected via the wireless features of the Nintendo DS. In this generation, the [[Pokéwalker]] is the only other place where Spiritomb is available.

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.

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

====Pokémon HeartGold and SoulSilver====
{{game|HeartGold and SoulSilver|s}} together have all the Pokémon from the [[List of Pokémon by Johto Pokédex number|Generation IV Johto Pokédex]] (which has 256 Pokémon in this generation), except for the event-exclusive {{p|Celebi}} and {{p|Mew}}. Alternatively, most Pokémon from the Johto Pokédex can be transferred from the Generation III games, except {{p|Ho-Oh}} and {{p|Lugia}} used to be event-exclusive in Generation III, and there are 5 new evolutions introduced to the Johto Pokédex in Generation IV.

In Pokémon HeartGold and SoulSilver, {{p|Magnezone}}, {{p|Probopass}}, {{p|Leafeon}}, and {{p|Glaceon}} cannot be obtained via [[evolution]] since there is no [[special magnetic field]], [[Moss Rock]], or [[Ice Rock]]. Those evolved Pokémon are unavailable except by trading from Pokémon Diamond, Pearl, and Platinum.

[[Spiky-eared Pichu]] is event-exclusive. The {{DL|List of event Pokémon with in-game effects|Pichu|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.

[[List of Pokémon found through the Pokéwalker|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 {{p|Castform}}, {{p|Feebas}}, and {{p|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.

{{p|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 {{p|Kyogre}} or {{p|Groudon}}.

===Generation V===
In [[Generation V]], there are 649 Pokémon.

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

Pokémon from Generation IV may be [[transfer]]red 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 {{p|Ekans}} and {{p|Diglett}}), but may be transferred from Generation IV as well.

====Pokémon Black and White====
{{game|Black and White|s}} together have all the non-event Pokémon from the first version of the Unova Pokédex (which has a total of {{OBP|List of Pokémon by Unova Pokédex number|Black and White|156 Pokémon}}).

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

In Black and White, the [[Relocator]] may be used to transfer certain event Pokémon from the Generation IV games for the purpose of catching {{p|Zorua}} and {{p|Zoroark}}. Zorua becomes available if the player transfers {{DL|List of event Pokémon with in-game effects|Celebi}}, and Zoroark becomes available if the player transfers the {{Shiny}} [[Legendary beasts]] ({{DL|List of event Pokémon with in-game effects|Raikou, Entei, and Suicune}}).

====Pokémon Black 2 and White 2====
{{game|Black and White|s 2|Pokémon Black 2 and White 2}} together have all the non-event Pokémon from the second version of the Unova Pokédex (which was expanded to a total of {{OBP|List of Pokémon by Unova Pokédex number|Black 2 and White 2|301 Pokémon}}).

{{p|Kyurem|White Kyurem, Black Kyurem}}, the Therian Forms of the [[Forces of Nature]] (Tornadus, Thundurus, and Landorus), and Resolute Form {{p|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, {{p|Regirock}}, {{p|Regice}} and {{p|Registeel}} can be caught in the [[Underground Ruins]]. However, Regice only appears in Black 2 if the player receives the Iceberg [[Key System|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. {{p|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.

{{p|Stunky}} and {{p|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, {{p|Magikarp}} and {{p|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.

===Generation VI===
In [[Generation VI]], there are 721 Pokémon.

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

Pokémon from Generation V can be [[transfer]]red one-way to the {{g|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 or that were sent from the [[Virtual Console]] releases of the [[Generation I]] and [[Generation II|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, {{p|Deerling}} and {{p|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====
{{g|X and Y}} together have all the non-event Pokémon from the three [[List of Pokémon by Kalos Pokédex number|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).

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, all Pokémon found in the Friend Safari are also available elsewhere in X, Y, Omega Ruby, or Alpha Sapphire.

====Pokémon Omega Ruby and Alpha Sapphire====
{{g|Omega Ruby and Alpha Sapphire}} together have all the non-event Pokémon from the {{gdis|List of Pokémon by Hoenn Pokédex number|VI|Generation VI Hoenn Pokédex}} (which has 211 Pokémon; all of them are from previous generations) and several other Pokémon as well.

Some [[Mega Evolution]]s, [[Primal Reversion]], the [[Cosplay Pikachu]], and {{p|Hoopa}} {{form|Hoopa|Unbound}} were introduced in Pokémon Omega Ruby and Alpha Sapphire, and are incompatible with Pokémon X and Y. Only one Cosplay Pikachu is available per game; it is unable to evolve, and it cannot be traded or transferred to any other games.

In Pokémon Omega Ruby and Alpha Sapphire, several Pokémon can be found in the [[Mirage spot]]s, 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]].

====Friend Safari and Mirage spots====
In the Generation VI games, the Pokémon below (and their evolutionary families, via evolution or breeding) can only be found in the [[Friend Safari]]{{sup/6|XY}} and in the random daily Mirage spots{{sup/6|ORAS}}. They may or may not be available at a certain point in time, 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 in both the Friend Safari and the daily Mirage spots:

* {{p|Venomoth}}
* {{p|Chansey}} (Friend Safari), {{p|Happiny}} (Mirage spots)
* {{p|Tangela}}
* {{p|Electabuzz}} (Friend Safari), {{p|Elekid}} (Mirage spots)
* {{p|Magmar}} (Friend Safari), {{p|Magby}} (Mirage spots)
* {{p|Sunkern}}
* {{p|Forretress}}
* {{p|Munna}}
* {{p|Zebstrika}}
* {{p|Excadrill}}
* {{p|Petilil}}
* {{p|Maractus}}
* {{p|Minccino}}
* {{p|Klink}} (Mirage spots), {{p|Klang}} (Friend Safari)
* {{p|Vullaby}}
* {{p|Larvesta}}

Available in the daily Mirage spots but not in the Friend Safari:

* {{p|Persian}}
* {{p|Porygon}}
* {{p|Unown}}
* {{p|Stantler}}
* {{p|Kricketune}}
* {{p|Cherrim}}
* {{p|Glameow}}, {{p|Purugly}}
* {{p|Darmanitan}}
* {{p|Cofagrigus}}
* {{p|Tynamo}}

===Generation VII===
In [[Generation VII]], there are 809 Pokémon. Prior to {{LGPE}}, there were 807 Pokémon. Prior to {{g|Ultra Sun and Ultra Moon}}, there were 802 Pokémon. There are also 18 [[Alolan form]]s available in all games of this generation.

====Pokémon Sun, Moon, Ultra Sun, and Ultra Moon====
In {{g|Sun and Moon}}, 786 Pokémon are available in-game and 16 Pokémon are event-exclusive ({{p|Mew}}, {{p|Jirachi}}, {{p|Phione}}, {{p|Manaphy}}, {{p|Darkrai}}, {{p|Shaymin}}, {{p|Arceus}}, {{p|Victini}}, {{p|Keldeo}}, {{p|Meloetta}}, {{p|Genesect}}, {{p|Diancie}}, {{p|Hoopa}}, {{p|Volcanion}}, {{p|Magearna}}, and {{p|Marshadow}}).

In {{g|Ultra Sun and Ultra Moon}}, some new Pokémon species and forms were introduced which are incompatible with Sun and Moon. 790 Pokémon are available in-game (the same as in Sun and Moon, with the additions of {{p|Poipole}}, {{p|Naganadel}}, {{p|Stakataka}}, and {{p|Blacephalon}}) and 17 Pokémon are event-exclusive (the same as in Sun and Moon, with the addition of {{p|Zeraora}}). The {{form|Necrozma|Dusk Mane, Dawn Wings, and Ultra forms}} of {{p|Necrozma}}, as well as the event-only {{DL|Pikachu in a cap|Partner Cap Pikachu}} and {{form|Lycanroc|Dusk Form}} {{p|Lycanroc}} were introduced in Ultra Sun and Ultra Moon as well.

{{p|Celebi}} used to be event-exclusive as well in Sun, Moon, Ultra Sun, and Ultra Moon prior to the [[Virtual Console]] release of {{game|Crystal}}.

Pokémon Sun, Moon, Ultra Sun, and Ultra Moon are compatible with the {{g|Bank}}. This allows the one-way transfer of Pokémon from earlier generations into these games (since the [[Generation VI]] games are also compatible with the Pokémon Bank, while the [[Generation V]] games and the [[Virtual Console]] version of [[Generation I]] and {{gen|II}} games can use the [[Poké Transporter]]).

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 {{OBP|List of Pokémon by Alola Pokédex number|Sun and Moon|302 Pokémon}} in the first pair of games and was expanded to {{OBP|List of Pokémon by Alola Pokédex number|Ultra Sun and Ultra Moon|403 Pokémon}} in the second pair of games). Some Pokémon outside the Alola Pokédex are also available in-game, but several other Pokémon from previous generations cannot be found in Sun, Moon, Ultra Sun, and Ultra Moon, except by being transferred from earlier generations.

The Spring Form of {{p|Deerling}} and {{p|Sawsbuck}} can be transferred from Generation VI games while the other forms of both Pokémon can be transferred from Generation V games.

====Pokémon: Let's Go, Pikachu! and Let's Go, Eevee!====
In {{LGPE}}, the first 150 Pokémon from the [[List of Pokémon by Kanto Pokédex number|Kanto Pokédex]] are available in-game (including their Alolan forms), and 3 additional Pokémon are available by other means: {{p|Mew}} by getting it from the [[Poké Ball Plus]] and {{p|Meltan}} and {{p|Melmetal}} by transferring them from {{g|GO}} via the [[GO Park]]. This pair of games is incompatible with all other Pokémon, the first [[core series]] games to do so, starting a trend that continued for all subsequent releases.

The {{ga|Partner Pokémon|partner}} {{p|Pikachu}} and partner {{p|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, regular Pikachu and Eevee are available in both games.

The games are incompatible with Pokémon Bank, but were later supported by Pokémon HOME.

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

No games in this generation feature every Pokémon. {{g|HOME}}, an application for storing and transferring Pokémon, is compatible with all 905 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 {{g|Bank}}, including those [[transfer]]red from previous generations, can be transferred to Pokémon HOME. Pokémon from {{LGPE}} can also be deposited into Pokémon HOME, and since November 10, 2020, it has been possible for Pokémon from {{g|GO}} to be transferred into Pokémon HOME via the [[GO Transporter]]. Additionally, some Pokémon have been directly {{gdis|List of game-based Pokémon distributions|VIII|distributed}} in Pokémon HOME, either as events or rewards for certain actions; most notably, the {{form|Magearna|Original Color}} {{p|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 a Generation VIII game, it can be moved to that game. Additionally, Pokémon can be moved from Generation VIII games into HOME, allowing them to be exchanged between all of the generation's games. However, if a {{pkmn2|Legendary}} or [[Mythical Pokémon]] (besides {{p|Meltan}} or {{p|Melmetal}}) is transferred to HOME from Pokémon GO, then it cannot be deposited into a game unless the player has already obtained one of its species in that game. {{g|Brilliant Diamond and Shining Pearl}} and {{g|Legends: Arceus}} were not compatible with Pokémon HOME until the Version 2.0.0 update, released on May 18, 2022.

====Pokémon Sword and Shield====
{{g|Sword and Shield}} are compatible with 664 Pokémon. Of these, 656 are available in-game and 8 are event-exclusive ({{p|Victini}}, {{p|Genesect}}, {{p|Diancie}}, {{p|Volcanion}}, {{p|Magearna}}, {{p|Marshadow}}, {{p|Zeraora}}, and {{p|Zarude}}). Prior to the release of [[The Crown Tundra]], {{p|Keldeo}} was also event-exclusive; prior to {{g|HOME}} becoming compatible with {{g|Brilliant Diamond and Shining Pearl}}, {{p|Mew}} and {{p|Jirachi}} were also event-exclusive.

* At first, only 401 Pokémon were obtainable, consisting of the 400 Pokémon from the [[List of Pokémon by Galar Pokédex number|Galar Pokédex]] and {{p|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 form|Galarian]] {{p|Slowpoke}} was added and made available to catch at [[Wedgehurst Station]], increasing the total number of obtainable Pokémon to 402.
* Ahead of the release of {{g|HOME}}, 6 additional Pokémon (the {{p|Bulbasaur}} and {{p|Squirtle}} lines) were made available in event Max Raid Battles, raising the total to 408.
* Upon the release of {{g|HOME}}, 34 additional Pokémon were made available via transfer from previous generations (including the event-exclusive {{p|Jirachi}}, {{p|Keldeo}}, {{p|Marshadow}}, and {{p|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 {{p|Zarude}}) not present in the [[List of Pokémon by Galar Pokédex number|Galar Pokédex]] became available as part of a new [[List of Pokémon by Isle of Armor Pokédex number|Isle of Armor Pokédex]], and {{p|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 {{p|Rowlet}}, {{p|Litten}}, {{p|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 {{p|Victini}}, {{p|Genesect}}, {{p|Diancie}}, and {{p|Volcanion}}) present in neither the [[List of Pokémon by Galar Pokédex number|Galar Pokédex]] nor the [[List of Pokémon by Isle of Armor Pokédex number|Isle of Armor Pokédex]] became obtainable, bringing the total to 664. Of these newly available Pokémon, 71 became available as part of a new [[List of Pokémon by Crown Tundra Pokédex number|Crown Tundra Pokédex]]. Additionally, 13 Pokémon that were previously exclusive to transfer from previous generations were made available through other means (including {{p|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 {{g|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 other games: {{p|Mew}} (which is also available via the Poké Ball Plus), {{p|Celebi}}, {{p|Jirachi}}, {{p|Victini}}, {{p|Genesect}}, {{p|Diancie}}, {{p|Volcanion}}, {{p|Magearna}}, {{p|Marshadow}}, {{p|Zeraora}}, {{p|Meltan}}, {{p|Melmetal}}, and {{p|Zarude}} (which is the only one of the 13 not obtainable via transfer from a previous generation). None of these 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 form|Galarian]] and [[Alolan form]]s. 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 {{p|Meowth}}, {{p|Yamask}}, and {{p|Mr. Mime}} are obtainable via [[in-game trade]]s.
* {{rf|Galarian}} {{p|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 {{g|HOME}}, the Alolan forms of {{p|Raichu}}, {{p|Vulpix}}, {{p|Ninetales}}, {{p|Diglett}}, {{p|Dugtrio}}, {{p|Meowth}}, and {{p|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 {{p|Sandshrew}}, {{p|Sandslash}}, {{p|Exeggutor}}, and {{p|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 {{p|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 {{p|Meowth}}, {{p|Ponyta}}, {{p|Farfetch'd}}, {{p|Weezing}}, {{p|Mr. Mime}}, {{p|Corsola}}, {{p|Zigzagoon}}, {{p|Darumaka}}, and {{p|Stunfisk}} and the Alolan forms of {{p|Exeggutor}} and {{p|Marowak}} can be obtained without requiring transfer (as can the original forms of {{p|Rapidash}}, {{p|Linoone}}, and {{p|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 {{DL|Fields of Honor|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 {{p|Meowth}} (after finding 5 Diglett), regular {{p|Slowpoke}} (after finding 10 Diglett), Alolan {{p|Vulpix}} (after finding 20 Diglett), Alolan {{p|Sandshrew}} (after finding 30 Diglett), Alolan {{p|Raichu}} (after finding 40 Diglett), Alolan {{p|Marowak}} (after finding 50 Diglett), Alolan {{p|Exeggutor}} (after finding 75 Diglett), and Alolan {{p|Diglett}} (after finding all 151 Diglett). By evolving these Pokémon, the Alolan forms of {{p|Persian}}, {{p|Ninetales}}, {{p|Sandslash}} and {{p|Dugtrio}} and the original forms of {{p|Slowbro}} and {{p|Slowking}} are also obtainable.
* With the release of [[The Crown Tundra]], the Galarian forms of {{p|Articuno}}, {{p|Zapdos}}, and {{p|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 Adventure]]s. Galarian {{p|Slowking}} was also added, with Galarian Slowpoke now being able to evolve into it.

====Pokémon Brilliant Diamond and Shining Pearl====
{{g|Brilliant Diamond and Shining Pearl}} are compatible with 493 Pokémon, consisting of every Pokémon from the first four [[generation]]s, as in the original {{game|Diamond and Pearl|s}}.

*491 Pokémon are obtainable in-game; but apart from [[transfer]]s, 3 ({{p|Mew}}, {{p|Jirachi}}, and {{p|Arceus}}) are only obtainable via [[save data bonus]]es, and 4 ({{p|Phione}}, {{p|Manaphy}}, {{p|Darkrai}}, and {{p|Shaymin}}) are only obtainable via events. The remaining 2 [[Mythical Pokémon]] ({{p|Celebi}} and {{p|Deoxys}}) are only obtainable via transfer.
**In order to obtain {{p|Mew}}, the player must have save data from {{LGPE|Pokémon: Let's Go, Pikachu! or Let's Go, Eevee!}} on their [[Nintendo Switch]] system. If this requirement is met, a {{tc|Gentleman}} in [[Floaroma Town]] will {{pkmn2|gift}} the player a Mew when spoken to.
**In order to obtain {{p|Jirachi}}, the player must have save data from {{pkmn|Sword and Shield|Pokémon Sword or Shield}} on their [[Nintendo Switch]] system. If this requirement is met, a {{tc|Madame}} in [[Floaroma Town]] will gift the player a Jirachi when spoken to.
**In order to obtain {{p|Arceus}} without transfer, the player must have save data from {{g|Legends: Arceus}} on their [[Nintendo Switch]] system, and they must have completed all of said game's 27 story [[Task|missions]] within this save data. If this requirement is met and the player has entered the [[Hall of Fame]] and obtained the [[National Pokédex]], they can obtain the [[Azure Flute]] in their [[Player's house|house]] in [[Twinleaf Town]], which can then be used at [[Spear Pillar]] to access the [[Hall of Origin]] and {{pkmn|battle}} and {{pkmn2|caught|catch}} Arceus. This is only possible in Version 1.3.0 or later.
**A [[Manaphy Egg]] was distributed through [[Mystery Gift]] via the Internet from November 19, 2021 to February 21, 2022. This {{pkmn|Egg}} can hatch into {{p|Manaphy}}, which can be {{pkmn|breeding|bred}} with {{p|Ditto}} to produce {{p|Phione}}.
**[[Oak's Letter]] was distributed through [[Mystery Gift]] via the Internet from February 27, 2022 to March 27, 2022. If the player brings this item to {{rt|224|Sinnoh}}, they can gain access to [[Flower Paradise]], where {{p|Shaymin}} can be encountered.

====Pokémon Legends: Arceus====
{{g|Legends: Arceus}} is compatible with 242 Pokémon. This includes all Pokémon that debuted in [[Generation IV]].

All 242 are obtainable in-game. Most are repeatedly catchable in one or more of the 5 main areas: [[Obsidian Fieldlands]], [[Crimson Mirelands]], [[Cobalt Coastlands]], [[Coronet Highlands]], and [[Alabaster Icelands]]. 

* However, the 5 [[Mythical Pokemon]] present (all of which are from [[Generation IV]]) have restricted accessibility. {{p|Arceus}} can only be obtained after obtaining 237 Pokemon; {{p|Manaphy}} and {{p|Phione}} almost surely requires external hints that are found in {{pkmn|Brilliant Diamond and Shining Pearl}}; and {{p|Darkrai}} and {{p|Shaymin}} are only unlockable via [[save data bonus]]es from other [[Generation VIII]] games.
** In order to obtain {{p|Arceus}}, the player must have caught all 237 non-Mythical Pokemon in the [[Hisui Pokedex]]. This unlocks the {{DL|Task|Missions|mission}} "The Deified Pokemon", in which Arceus can be obtained.
** In order to obtain {{p|Manaphy}} and {{p|Phione}}, the player must have Quelled [[Noble Pokémon#Lord of the Isles: Arcanine|Lord Arcanine]] and have a [[Rank (Galaxy Team)|star rank]] of 5, making the {{DL|Task|Requests|request}} "The Sea's Legend" available.

If successful, Manaphy and three Phione can be caught in Seaside Hollow, with Phione being a rare spawn thereafter. 
** In order to obtain {{p|Darkrai}}, the player must have save data from {{pkmn|Brilliant Diamond and Shining Pearl|Pokémon Brilliant Diamond or Shining Pearl}} on their [[Nintendo Switch]] system. If this requirement is met and the main story of Legends: Arceus has been completed, the {{DL|Task|Requests|request}} "The Darksome Nightmare" will become available, in which a Darkrai can be caught.
** In order to obtain {{p|Shaymin}}, the player must have save data from {{pkmn|Sword and Shield|Pokémon Sword or Shield}} on their [[Nintendo Switch]] system. If this requirement is met and the main story of Legends: Arceus has been completed, the {{DL|Task|Requests|request}} "A Token of Gratitude" will become available, in which a Shaymin can be caught.

* Additionally, Alolan {{p|Vulpix}} and the 13 [[Legendary Pokemon]] can only be obtained through {{OBP|List of in-game event Pokémon|Legends: Arceus|in-game events}}.
** In order to obtain Alolan {{p|Vulpix}}, the player must catch the original form of {{p|Vulpix}} and obtain Hisuian {{p|Braviary}} as a ride Pokemon. If these requirements are met, the request "Snow-White Vulpix in the Snow" will become available, in which an Alolan Vulpix is gifted.
** {{p|Dialga}} and {{p|Palkia}} can be caught towards to the end of the main story.
** {{p|Uxie}}, {{p|Mesprit}}, {{p|Azelf}}, {{p|Heatran}}, {{p|Cresselia}} and {{p|Regigigas}} can be caught in the post-game story.
** {{p|Giratina}}, {{p|Thundurus}}, {{p|Tornadus}} and {{p|Landorus}} can be caught after defeating Volo in the Temple of Sinnoh.
** {{p|Enamorus}} is only obtainable after catching Thundurus, Tornadus and Landorus first.

* Furthermore, obtaining {{p|Spiritomb}} requires collecting all wisps first (20 in each main area and 7 in [[Jubilife Village]]); and obtaining more {{p|Unown}} requires catching a single specimen of each form first (5 in each main area and 3 in Jubilife Village). The player can also only obtain one [[Starter Pokémon#Hisui|Hisuian Starter Pokémon]] in-game until completion of the main story.

=====Variant Availability=====

In total, Pokémon Legends: Arceus is compatible with 369 [[forms]], including all 17 new {{rf|Hisuian|form}}s. All Hisuian forms replace their original forms, except in the case of {{p|Sneasel}}, where both forms are included. 242 forms make up unique species, with an additional 59 forms being the result of [[gender differences]]. In addition to this, there are a further 27 {{p|Unown}}, 5 {{p|Rotom}}, 2 {{p|Burmy}} and 2 {{p|Wormadam}} forms; and a further 6 forms accounted by West/East Sea {{p|Shellos}} and {{p|Gastrodon}}, Alolan/Original {{p|Vulpix}} and {{p|Ninetales}}, Hisuian/Original {{p|Sneasel}}, and Overcast/Sunshine {{p|Cherrim}}. The remaining 26 forms, not yet counted, consist of 18 separate {{p|Arceus}} forms, as well as alternate forms for {{p|Tornadus}}, {{p|Thundurus}}, {{p|Landorus}}, {{p|Enamorus}}, {{p|Dialga}}, {{p|Palkia}}, {{p|Giratina}} and {{p|Shaymin}}. Cherrim cannot appear in its Sunshine form when stored and Legend Plate Arceus appears as Blank Plate Arceus when stored. Legend Plate Arceus also does not count as a separate form entry in the Pokédex. Heights and weights for gender differences, except {{p|Basculegion}}, are not recorded separately in the Pokédex. Not included in the 369 total, are 2 additional {{p|Mothim}} forms, only separated internally, which are a result of evolution from either Plant, Sandy or Trash Cloak Burmy. 

All forms can be obtained as [[alpha]] Pokémon except Alolan Vulpix, Alolan Ninetales, and those of the 18 in-game [[Legendary]] and [[Mythical]] Pokémon, totaling 46 forms excluded. All alpha Pokémon are the largest possible specimens for their species except {{p|Gyarados}}, {{p|Onix}}, {{p|Steelix}}, {{p|Rhyperior}} and Hisuian {{p|Avalugg}}. Only one Alolan Vulpix (or Alolan Ninetales), and only one of each of the in-game Legendary and Mythical Pokémon (except {{p|Phione}}) can be obtained (and only in their average size) without transferring.

All forms and their alpha equivalents can be {{Shiny}}; however, Alolan Vulpix, Alolan Ninetales, and the in-game Legendary and Mythical Pokémon are Shiny-locked and thus cannot be obtained Shiny without transferring them into the game. Shiny {{p|Enamorus}} is not currently legally obtainable as a result. Additionally, several {{OBP|List of in-game event Pokémon|Legends: Arceus|in-game event Pokémon}} are Shiny-locked, but can be captured in the wild Shiny.

A selection of Pokémon can only be obtained in-game via rare spawns in [[Space-time distortion|Space-time distortions]], making their alpha, in-game Shiny, and Shiny alpha forms generally considered the rarest to collect in the game. These rare Pokémon are the original forms of {{p|Sneasel}} and {{p|Weavile}} (in [[Obsidian Fieldlands]]); {{p|Porygon}}, {{p|Porygon2}} and {{p|Porygon-Z}} (in [[Crimson Mirelands]]); {{p|Magnemite}} and {{p|Magneton}} (in [[Cobalt Coastlands]]); and {{p|Shieldon}}, {{p|Bastiodon}}, {{p|Cranidos}}, and {{p|Rampardos}} (in [[Coronet Highlands]]). In addition, alpha and Shiny alpha {{p|Magnezone}} can only be obtained by catching (or evolving from) a rare space-time distortion spawn. Two similiarly rare categories are Pokémon obtained exclusively from shaking trees, namely {{p|Burmy}} and {{p|Wormadam}}; and female specimens of a species with a [[List of Pokémon by gender ratio#1 ♀ : 7 ♂|7-male-to-1-female ratio]], including the visibly gender different {{p|Eevee}} and {{p|Combee}}.

A total of 519 gender-form combinations (including Sunshine {{p|Cherrim}} and Legend Plate {{p|Arceus}}) are possible. 201 species, and 209 out of 310 forms (excluding gender differences), can be both female and male, amounting to 418 combinations after doubling. The remaining combinations are from 101 single gender forms across 41 species, further divided into 24 [[List of Pokémon by gender ratio#Gender_unknown|gender unknown]] species ({{p|Unown}}, the {{p|Porygon}} line, the {{p|Magnemite}} line, the Hisuian {{p|Voltorb}} line, the {{p|Bronzor}} line, {{p|Rotom}}, {{p|Uxie}}, {{p|Mesprit}}, {{p|Azelf}}, {{p|Regigigas}}, {{p|Dialga}}, {{p|Palkia}}, {{p|Giratina}}, {{p|Arceus}}, {{p|Phione}}, {{p|Manaphy}}, {{p|Shaymin}} and {{p|Darkrai}}) with a total of 78 forms; 7 [[List of Pokémon by gender ratio#Male_only|male-only]] species ({{p|Mothim}}, {{p|Gallade}}, {{p|Rufflet}}, Hisuian {{p|Braviary}}, {{p|Tornadus}}, {{p|Thundurus}} and {{p|Landorus}}) with a total of 10 forms; and 10 [[List of Pokémon by gender ratio#Female_only|female-only]] species ({{p|Wormadam}}, {{p|Vespiquen}}, {{p|Happiny}}, {{p|Chansey}}, {{p|Blissey}},  {{p|Petilil}}, {{p|Lilligant}}, {{p|Froslass}}, {{p|Cresselia}} and {{p|Enamorus}}) with a total of 13 forms. For [[alpha]]s, there are a total of 470 combinations, 49 less combinations, which consists of 46 less alpha forms for one gender and 3 less alpha forms (Alolan {{p|Vulpix}}, Alolan {{p|Ninetales}}, and {{p|Heatran}}) for the opposite gender.

=====Pokémon HOME Interaction=====

Following the introduction of {{g|HOME}} compatibility, the ability to transfer alpha Pokémon to other [[Generation VIII]] games became available. A consequence of this is an alpha Pokémon can be evolved into a different [[regional form]] (or species) not compatible with Pokémon Legends: Arceus, giving rise to 9 HOME-exclusive alpha forms: the original forms of {{p|Typhlosion}}, {{p|Lilligant}}, {{p|Braviary}}, {{p|Sliggoo}}, {{p|Goodra}}, {{p|Avalugg}}, {{p|Decidueye}}; the Galarian form of {{p|Mr. Mime}}; and {{p|Mr. Rime}}. A 10th HOME-exclusive alpha form became available following the {{g|Scarlet and Violet}}-HOME compatibility update: the original form of {{p|Samurott}}; however, the alpha icon no longer displays for the HOME-exclusive alphas. Instead, an alpha mark is obtained if any alpha is transferred to Scarlet and Violet. All HOME-exclusive alpha forms except the Galarian form of {{p|Mr. Mime}} and {{p|Mr. Rime}} can be transferred and therefore obtain the alpha mark. 

Before {{g|Scarlet and Violet}} received integration with {{g|HOME}} in HOME v3.0.0, Pokémon originating from {{g|Ultra Sun and Ultra Moon}} or earlier that were then transferred into Legends: Arceus (via {{g|Bank}} and HOME) received minimum [[Size and weight variation|heights and weights]] (scalar values of 0, as prior to {{pkmn|Let's Go, Pikachu! and Let's Go, Eevee!}} distinct values for height and weight were not generated); following the update, randomized heights and weights will be assigned to them instead, provided they haven't been assigned a size already by being transferred to another [[Generation VIII]] or {{gen|IX}} game.

In {{g|GO}}, as part of its [[Size_and_weight_variation#Pokémon GO|size variation]] mechanic, XXS and XXL Pokémon each have a 1 in 250 chance to be generated. When one of these extreme-sized Pokémon is obtained and transferred to {{g|HOME}} and then into {{g|Legends: Arceus}}, both its height and weight scalar values are set to either 0 or 255, depending on whether it was initially XXS or XXL, respectively. This results in the specimen having the minimum or maximum possible in-game height and weight for its species (or form). In contrast, generation of both of these values for a native Pokémon in Legends: Arceus has less than a 1 in 250 million chance to occur—albeit due to a lack of display precision, additional values may also give the minimum and maximum possible measurements depending on the Pokémon species/form.

===Generation IX===
In [[Generation IX]], there are 1025 Pokémon, but not all of them are obtainable.
