View source for Pokémon availability

There are various means of obtaining {{OBP|Pokémon|species}} in the {{pkmn|games}}. In all [[core series]] games, some Pokémon may be {{pkmn2|caught}} and others are available via [[Evolution]]. There are various [[methods of Evolution]], such as by reaching a certain [[level]], using an [[Evolution stone]], or via [[trade]]. Other methods to obtain Pokémon also exist, including [[breeding]], [[in-game trade]]s, [[gift Pokémon]], and through {{pkmn2|event}}s. Some Pokémon may not be available in a certain game, but may be traded from another game or [[transfer]]red from an earlier [[generation]].

Up to and including [[Pokémon Ultra Sun and Ultra Moon]], each core series game was compatible with all Pokémon species released to date, either from the current game itself or from 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.

===First partner Pokémon===
{{main|First partner Pokémon}}
The [[first partner Pokémon]] is given to the player at the start of their [[Pokémon journey]]. In most core series {{pkmn|games}}, the player can choose a {{t|Fire}}-, {{t|Water}}-, or {{type|Grass}} first partner Pokémon at [[level]] 5. At least one of the player's [[rival]]s or [[friend]]s also has a first partner Pokémon, which may either have a type advantage or disadvantage over the player's depending on the game.

In {{game|Yellow}} and {{LGPE}}, the player instead receives the {{type|Electric}} {{p|Pikachu}} or {{type|Normal}} {{p|Eevee}} as their first Pokémon.

===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 tile|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 [[first partner Pokémon]], some [[Fossil|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 [[first partner Pokémon]] 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 first partner Pokémon 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}}). Across the Japanese {{game|Red and Green|s}}, as well as the international releases of {{game|Red and Blue|s}}, the first 150 Pokémon can be obtained without events.

The Japanese Pokémon Red and Green each feature 135 Pokémon available without trading or events, with 11 exclusive to each version and 4 obtained through [[trade Evolution]]. 137 Pokémon are available in the Japanese {{jpn|Pokémon Blue Version|Pokémon Blue}}, with 11 Pokémon only found on other versions and 2 trade Evolutions, as {{p|Golem}} and {{p|Gengar}} can now be obtained from in-game trades. The international releases of Pokémon Red and Blue feature identical Pokémon distributions to the Japanese Red and Green, respectively.

{{game|Yellow}} similarly features 134 Pokémon available without trading, with 13 Pokémon only found on other versions and 3 trade Evolutions, as {{p|Machamp}} can be received in-game. Only [[Pikachu (Yellow)|a single Pikachu]] is available as the player's first 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.

{{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.

===Generation II===
In [[Generation II]], there are 251 Pokémon. Across the original releases of [[Pokémon Gold]], [[Pokémon Silver|Silver]], and [[Pokémon Crystal|Crystal]], only 232 Pokémon are available without events, as {{p|Bulbasaur}}, {{p|Charmander}}, {{p|Squirtle}}, {{p|Omanyte}}, {{p|Kabuto}}, {{p|Articuno}}, {{p|Zapdos}}, {{p|Moltres}}, {{p|Mewtwo}}, {{p|Mew}}, {{p|Celebi}}, and their respective Evolutions cannot be obtained. However, all of these Pokémon excluding Mew and Celebi can be obtained by trading with Generation I games; additionally, the [[Virtual Console]] release of Pokémon Crystal includes Celebi as a non-event Pokémon, for a total of 233 available Pokémon.

Pokémon Gold, Silver, and Crystal each feature 212 Pokémon available without trading or events, with 10 Pokémon only found on other versions and 10 trade Evolutions, as well as the aforementioned unobtainable Pokémon. 

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 [[List of European language event Pokémon distributions in Generation 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 including international releases, bringing the total to 213 available Pokémon.

===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}}). Ho-Oh, Lugia, and Deoxys are normally available in the Nintendo Switch releases of {{game|FireRed and LeafGreen|s}}, for a total of 383 available Pokémon.

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 {{p|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 and Sapphire====
In {{game|Ruby and Sapphire|s}}, the first 200 Pokémon from the [[List of Pokémon by Hoenn Pokédex number in Generation III|Generation III Hoenn Pokédex]] are available across both games; the first 133 Pokémon introduced in this Generation are available, as well as 47 Pokémon from Generation I and 20 Pokémon from Generation II. Ruby and Sapphire each have 186 Pokémon available without trading, with 8 version-exclusive Pokémon and 6 trade Evolutions. {{p|Latias}} and {{p|Latios}} can be caught in Pokémon Ruby and Sapphire respectively through the [[Eon Ticket]] event.

====Pokémon FireRed and LeafGreen====
Across {{game|FireRed and LeafGreen|s}}, there are 212 Pokémon available in-game. This increases to 215 Pokémon (adding {{p|Lugia}}, {{p|Ho-Oh}}, and {{p|Deoxys}}) for the Nintendo Switch release, as two previously event-exclusive items (the MysticTicket and the AuroraTicket), that unlock an area each, become obtainable through normal gameplay.

The first 150 Pokémon from the [[List of Pokémon by Kanto Pokédex number|Kanto Pokédex]] are available in-game, subject to trading between versions. The remaining 62 (or 65) Pokémon additionally require the [[National Pokédex]] and are obtained in the post-game along with {{p|Mewtwo}}. 60 (or 62, counting Lugia and Ho-Oh) of these Pokémon are from [[Generation II]], while 2 other Generation II Pokémon offspring, {{p|Azurill}} and {{p|Wynaut}}, (as well as Deoxys) are from [[Generation III]]. Other than a single {{pkmn2|roaming}} {{p|Raikou}}/{{p|Entei}}/{{p|Suicune}} encounter in Kanto, these non-Kanto Pokémon can all obtained around the latter four [[Sevii Islands]] via encounters or from a gift, by {{pkmn|breeding}} on [[Four Island]], or by [[List of Pokémon by evolutionary line|Evolution]].

The [[MysticTicket]] allows for Ho-Oh and Lugia to both be caught on [[Navel Rock]], while the [[AuroraTicket]] allows Deoxys to be caught on [[Birth Island]]. {{p|Mew}} was an event-exclusive giveaway and therefore cannot be obtained in the Switch release.

Up to 25 Generation II Pokémon ({{p|Sentret}}, {{p|Ledyba}}, {{p|Spinarak}}, {{p|Natu}}, {{p|Marill}}, {{p|Hoppip}}, {{p|Yanma}}, {{p|Wooper}}, {{p|Murkrow}}, {{p|Misdreavus}}, {{p|Unown}}, {{p|Wobbuffet}}, {{p|Dunsparce}}, {{p|Qwilfish}}, {{p|Heracross}}, {{p|Sneasel}}, {{p|Slugma}}, {{p|Magcargo}}, {{p|Swinub}}, {{p|Remoraid}}, {{p|Delibird}}, {{p|Mantine}}, {{p|Skarmory}}, {{p|Phanpy}}, and {{p|Larvitar}}) are available to be repeatedly caught in the Sevii Islands.

Only 11 Pokémon species need to be bred to be obtained, consisting of the 9 out of 10 [[baby Pokémon]] as of Generation III ({{pkmn2|Gift}} {{p|Togepi}} is the 10th), and 2 more {{p|Tyrogue}} to evolve into the other {{p|Hitmonlee}}/{{p|Hitmonchan}} and {{p|Hitmontop}}. Additionally, 4 Pokémon ({{p|Farfetch'd}}, {{p|Lickitung}}, {{p|Mr. Mime}}, and {{p|Jynx}}) are exclusively obtained in [[In-game trade#Pokémon FireRed and LeafGreen|in-game trades]] and thus have to be bred (and evolved in the case of Jynx) to obtain them in one's own Trainer name and ID. The items needed to obtain the 2 Generation III baby Pokémon, as well as the 6 cross-generational [[trade Evolution]]s, are obtainable in the post-game.

A total of 59 Pokémon cannot be obtained in-game without evolving. 35 of these are from Generation I and consist of: the 16 Kanto Pokémon that evolve by [[Evolution stone]]s as of Generation III; the 6 Kanto {{pkmn2|first partner}} Evolutions; the 4 Kanto trade Evolutions ({{p|Alakazam}}, {{p|Machamp}}, {{p|Golem}}, and {{p|Gengar}}); {{p|Omastar}} and {{p|Kabutops}}; and 7 others ({{p|Butterfree}}, {{p|Beedrill}}, {{p|Pidgeot}}, {{p|Dodrio}}, one of Hitmonlee/Hitmonchan, {{p|Rhydon}}, and {{p|Dragonite}}). The remaining 24 are from Generation II, with Magcargo being the sole exception for Generation II as it is catchable in [[Mt. Ember]]. Additionally, {{p|Seadra}} can only be caught in FireRed, and {{p|Nidorina}}, {{p|Nidorino}}, and {{p|Dragonair}} can only be caught in the {{ka|Safari Zone}}. However, Nidorina and Nidorino can also be obtained in in-game trades in FireRed and LeafGreen, respectively.

Without trading or transfers, Pokémon FireRed has 170 (or 173) Pokémon available versus Pokémon LeafGreen having 171 (or 174) available. Both versions have 13 Kanto and 8 Johto [[Version-exclusive Pokémon#FireRed and LeafGreen|version-exclusives]], but LeafGreen additionally has Azurill exclusive. Apart from these 22 or 21 missing Pokémon, and the 10 trade Evolutions, another 10 are missed due to branched choices: 6 of the Kanto first partner Pokémon (2 evolutionary lines), 2 fossil Pokémon (either the {{p|Kabuto}} or {{p|Omanyte}} line) and 2 of the [[Legendary beasts]]. 2 of the trade Evolutions, {{p|Scizor}} and {{p|Slowking}}, evolve from version-exclusive {{p|Scyther}} and {{p|Slowpoke}} from FireRed and LeafGreen respectively, so may account for an additional version-exclusive each depending on definition.

All Pokémon except the 7 (or 10) in-game {{pkmn2|Legendary}} and [[Mythical Pokémon]] (19 in Gen III in total) have the potential to be obtained in-game repeatedly due to almost every other Pokémon being able to be obtained through a combination of breeding an obtained Pokémon and evolving where necessary. {{p|Ditto}} and {{p|Unown}}, the two others that can't be bred, can be repeatedly encountered and caught. Restricting to FireRed and LeafGreen in-game availability, at most 1 out of 3 save files can possess the full 212 (or 215) available Pokémon because only 1 out of 3 Legendary beasts are obtainable per save file.

An additional 22 Pokémon can also be seen in in-game trainer teams but not caught: 5 exclusive to the [[Trainer Tower]] ({{p|Feraligatr}}, {{p|Ampharos}}, {{p|Espeon}}, {{p|Granbull}}, and {{p|Corsola}}) and 17 ({{p|Hoothoot}}, {{p|Noctowl}}, {{p|Chinchou}}, {{p|Lanturn}}, {{p|Mareep}}, {{p|Flaaffy}}, {{p|Sudowoodo}}, {{p|Sunkern}}, {{p|Sunflora}}, {{p|Girafarig}}, {{p|Pineco}}, {{p|Snubbull}}, {{p|Ursaring}}, {{p|Houndour}}, {{p|Houndoom}}, {{p|Smeargle}}, and {{p|Miltank}}) in locations around {{isl|Five}}, {{isl|Six}} and {{isl|Seven}} Islands.

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

{{game|FireRed and LeafGreen|s}} combined have up to 239 [[List of Pokémon with form differences|forms]] (or 243 in the Nintendo Switch release format) to collect in-game. This includes the 212 species (215 with {{p|Lugia}}, {{p|Ho-Oh}}, and {{p|Deoxys}}) along with the 27 other {{p|Unown}} forms, plus the (AuroraTicket) Deoxys Forme locked to the opposite version (Attack{{Sup/3|FR}} or Defense{{Sup/3|LG}}). All forms are also available {{pkmn2|Shiny}} and have a 1/8192 chance to be Shiny except Unown, which has different odds depending on its form and the save file's Trainer and Secret IDs.

There are a total of 418 (or 422) gender-form combinations of in-game Pokémon, which is just below the maximum storage of 426 (14 boxes of 30 plus 6 party slots). 179 species have 2 genders, resulting in 358 combinations. The remaining 60 (or 64) combinations result from 8 male-only species ({{p|Nidoran♂}}, {{p|Nidorino}}, {{p|Nidoking}}, {{p|Hitmonlee}}, {{p|Hitmonchan}}, {{p|Tauros}}, {{p|Tyrogue}}, {{p|Hitmontop}}), 8 female-only species ({{p|Nidoran♀}}, {{p|Nidorina}}, {{p|Nidoqueen}}, {{p|Chansey}}, {{p|Kangaskhan}}, {{p|Jynx}}, {{p|Smoochum}}, and {{p|Blissey}}), and 44 (or 48) gender unknown forms (28 Unown; 8 from the {{p|Magnemite}}, {{p|Voltorb}}, {{p|Staryu}}, and {{p|Porygon}} lines; 8 consisting of {{p|Ditto}}, {{p|Articuno}}, {{p|Zapdos}}, {{p|Moltres}}, {{p|Mewtwo}}, {{p|Raikou}}, {{p|Entei}}, and {{p|Suicune}}; and the remaining 4 of Lugia, Ho-Oh, and both version-locked Deoxys).

A total of 322 (or 326) [[List of Pokémon by Ability|Ability]]-form combinations of in-game Pokémon exist, consisting of 129 (or 132) species with 1 Ability, 83 species with 2 Abilities (166 combinations), and an additional 27 Unown forms (and 1 extra version-locked Deoxys) with 1 Ability. 8 Pokémon with a single gender (Magnemite, Voltorb, Chansey, Staryu and their Evolutions) have 2 abilities, therefore a minimum of 426 (or 430) Pokémon are needed to collect both Ability and gender combinations separately.

=====Level Availability=====

All but five Pokémon ({{p|Dragonite}}, {{p|Mewtwo}}, {{p|Tyranitar}}, {{p|Lugia}}, and {{p|Ho-Oh}}) can be obtained at level 50 or below. {{p|Articuno}}, {{p|Zapdos}}, {{p|Moltres}} and {{p|Raikou}}, {{p|Entei}}, {{p|Suicune}} are obtained exactly at level 50, while Deoxys is obtained at level 30. {{p|Kadabra}} needs to be evolved from {{p|Abra}} to obtain it below level 50.

117 in-game Pokémon are available at level 5. This includes the unevolved Pokémon in 72 out of the 78 Kanto [[List of Pokémon by evolutionary line|evolutionary lines]] ({{p|Ditto}}, Articuno, Zapdos, Moltres, Mewtwo and the event-exclusive {{p|Mew}} cannot be bred) and 24 out of the 51 Johto evolutionary lines ({{p|Unown}}, Raikou, Entei, Suicune, Lugia and Ho-Oh cannot be bred, and the rest aren't obtainable), with {{p|Azurill}} and {{p|Wynaut}} also being able to be bred via items, bringing the total so far to 98. Another 4 species ({{p|Metapod}}, {{p|Kakuna}}, {{p|Pikachu}}, and {{p|Jigglypuff}}) can be found in early routes at level 5 or below, and a further 4 species ({{p|Slowking}}, {{p|Steelix}}, {{p|Scizor}}, and {{p|Porygon2}}) [[Trade Evolution|evolve by trade]] while holding an item. 10 more evolve via [[Evolution stone]] ({{p|Raichu}}, {{p|Ninetales}}, {{p|Wigglytuff}}, {{p|Arcanine}}, {{p|Cloyster}}, {{p|Exeggutor}}, {{p|Starmie}}, {{p|Vaporeon}}, {{p|Jolteon}}, and {{p|Flareon}}); and finally, {{p|Electrode}} can be received in an [[In-game trade#Pokémon FireRed and LeafGreen|in-game trade]] for Raichu.

At level 70, Mewtwo, Lugia and Ho-Oh are the highest level encounters; otherwise Ditto and Kadabra at level 67 in the [[Cerulean Cave]] are the highest level wild Pokémon.

Level 2 is the lowest level one can obtain a Pokémon at: {{p|Pidgey}} and {{p|Rattata}} on {{rt|1|Kanto}}, and {{p|Mankey}} on {{rt|22|Kanto}}. {{p|Caterpie}}, {{p|Weedle}}, {{p|Spearow}}, Pikachu and Jigglypuff are catchable at level 3; and Metapod{{Sup/3|LG}} and Kakuna{{Sup/3|FR}} at level 4.

=====Availability by Poké Ball=====

All 5 Generation I [[Poké Ball]]s (the [[Poké Ball (item) | Poké Ball]], [[Great Ball]], [[Ultra Ball]], [[Master Ball]], and [[Safari Ball]]), as well as the 7 Generation III Poké Balls (the [[Net Ball]], [[Dive Ball]], [[Nest Ball]], [[Repeat Ball]], [[Timer Ball]], [[Luxury Ball]], and [[Premier Ball]]) are compatible with these games. However, the Dive Ball and Premier Ball are not available in-game and must be traded in. Furthermore, only 1 Master Ball is obtainable in-game, and the Luxury, Nest and Net Balls cannot be bought in these games.

* All Pokémon can be obtained in the Poké Ball, although the 4 Safari-Zone-exclusives ({{p|Rhyhorn}}, {{p|Chansey}}, {{p|Kangaskhan}}, and {{p|Tauros}}) need to be bred to obtain them in the Poké Ball. {{p|Rhydon}} and {{p|Blissey}} must then be evolved from the bred Rhyhorn and Chansey, respectively.

* Up to 39 in-game Pokémon can be obtained in the Safari Ball: 16 in the {{ka|Safari Zone}}'s tall grass ({{p|Nidoran♀}}, {{p|Nidorina}}, {{p|Nidoran♂}}, {{p|Nidorino}}, {{p|Paras}}, {{p|Parasect}}, {{p|Venonat}}, {{p|Venomoth}}, {{p|Doduo}}, {{p|Exeggcute}}, Rhyhorn, Chansey, Kangaskhan, {{p|Scyther}}{{Sup/3|FR}}, {{p|Pinsir}}{{Sup/3|LG}}, and Tauros), 8 in the water ({{p|Psyduck}}{{Sup/3|FR}}, {{p|Poliwag}}, {{p|Slowpoke}}{{Sup/3|LG}}, {{p|Goldeen}}, {{p|Seaking}}, {{p|Magikarp}}, {{p|Dratini}}, and {{p|Dragonair}}), and 15 via Evolution only ({{p|Nidoqueen}}, {{p|Nidoking}}, {{p|Golduck}}{{Sup/3|FR}}, {{p|Poliwhirl}}, {{p|Poliwrath}}, {{p|Slowbro}}{{Sup/3|LG}}, {{p|Dodrio}}, {{p|Exeggutor}}, Rhydon, {{p|Gyarados}}, {{p|Dragonite}}, {{p|Politoed}}, {{p|Slowking}}, {{p|Scizor}}, and Blissey).

* All except 50 in-game Pokémon can be obtained in the other types of Poké Ball. The exceptions include the 24 [[Gift Pokémon#FireRed and LeafGreen|gift]]-related Pokémon (the {{p|Bulbasaur}}, {{p|Charmander}}, {{p|Squirtle}}, {{p|Eevee}}, {{p|Omanyte}}, {{p|Kabuto}}, {{p|Togepi}}, and {{p|Tyrogue}} lines, in addition to {{p|Aerodactyl}}) that cannot be caught in the wild, as well as the remaining 8 Generation II and III [[baby Pokémon]]. The other exceptions consist of the 6 Safari-Zone-exclusive Pokémon and their Evolutions (Rhyhorn, Rhydon, Chansey, Kangaskhan, Tauros, and Blissey); the 6 Pokémon obtained from either the Safari Zone, or the [[Celadon Game Corner]], and their Evolutions (Scyther{{Sup/3|FR}}, Pinsir{{Sup/3|LG}}, Dratini, Dragonair, Dragonite, and Scizor); the 4 [[In-game trade#Pokémon FireRed and LeafGreen|in-game-trade]]-exclusives ({{p|Farfetch'd}}, {{p|Lickitung}}, {{p|Mr. Mime}}, and {{p|Jynx}}); and the 2 that make up the Game-Corner-exclusive {{p|Porygon}} line.

====Pokémon Emerald====
{{game|Emerald}} features most of the Pokémon found in Pokémon Ruby and Sapphire. Particularly, 187 of the Pokémon in Ruby and Sapphire are available without trading, with 6 trade Evolutions for these Pokémon and 7 Pokémon exclusive to Ruby and Sapphire. After the [[National Pokédex]] is obtained, 33 [[Generation II]] Pokémon become available (almost all found in the {{ho|Safari Zone}}). Several of 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 total, Pokémon Emerald has 220 Pokémon available without trading or connecting with other games.

In Emerald, the player can receive one of the [[Johto first partner Pokémon]] after obtaining all non-event Pokémon in the Hoenn Pokédex, which requires trading with Ruby and Sapphire. {{p|Surskit}}, which is one of the Pokémon exclusive to Ruby and Sapphire, can also be found on the wild by [[record mixing]] with either of these two games.

Ho-Oh, Lugia, and Deoxys can also be caught in this game as with FireRed and LeafGreen. {{p|Mew}} can be caught on [[Faraway Island]] 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 [[List of English event Pokémon distributions in Generation 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 63 available Pokémon outside of trades: 2 Pokémon that the player starts with ({{p|Espeon}} and {{p|Umbreon}}), [[List of Shadow Pokémon|48 Shadow Pokémon]], 11 Evolutions of Shadow Pokémon, and {{p|Ho-Oh}} and {{p|Plusle}} as gifts. 3 more Shadow Pokémon, {{p|Togepi}}, {{p|Mareep}}, and {{p|Scizor}}, can be found in the [[Card e Room]] exclusive to the Japanese version, while {{p|Celebi}} can also be obtained in the Japanese version through the [[Pokémon Colosseum Bonus Disc]], for a total of 67 obtainable Pokémon.

In {{g|XD: Gale of Darkness}}, there are 163 available Pokémon outside of trades: the single Pokémon that the player starts with, {{p|Eevee}}, and its 5 [[Eeveelution]]s in Gen III (of which [[Mutually exclusive Pokémon#Pokémon XD: Gale of Darkness|only one can be obtained]]), [[List of Shadow Pokémon|83 Shadow Pokémon]], 37 Evolutions of Shadow Pokémon, 9 [[Poké Spot|wild Pokémon]] and their 12 Evolutions, 4 Pokémon received from in-game trades ({{p|Shuckle}}, {{p|Elekid}}, {{p|Larvitar}}, {{p|Meditite}}) and their 3 Evolutions, the 3 [[Johto first partner Pokémon]] from [[Mt. Battle]], and the 6 Evolutions of Johto first partner 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}}; this is the only way to obtain these two Pokémon in the Generation III games without events. 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}}). Pokémon from the Generation III games may be [[transfer]]red to Generation IV with Pokémon [[Pokémon Diamond|Diamond]], [[Pokémon Pearl|Pearl]], and [[Pokémon Platinum|Platinum]], with 4 Pokémon only being obtainable (outside of events) by transferring from a Generation III game ({{p|Regirock}}, {{p|Regice}}, {{p|Registeel}}, and {{p|Regigigas}}). 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.

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 giants]] from the Generation III games via the Pal Park and use them to obtain Regigigas.

====Pokémon Diamond and Pearl====
In {{game|Diamond and Pearl|s}}, 397 Pokémon are available by trading or connecting with both games. The first 150 Pokémon in the [[Sinnoh Pokédex]] can be caught (excluding {{p|Manaphy}}), which includes 32 Pokémon from Generation I, 22 from Generation II, 16 from Generation III, and 80 Pokémon introduced in these games. After obtaining the [[National Pokédex]] and [[Poké Radar]], 247 more Pokémon become available: 88 from Generation I, 55 from Generation II, 87 from Generation III, and 17 Pokémon introduced in these games, for a total of 120, 77, 103, and 97 Pokémon from each Generation respectively.

363 Pokémon are available without trading or other game connectivity in Diamond and Pearl (138 in the Sinnoh Pokédex, 225 in the National Pokédex), with 14 [[trade Evolution]]s and 19 version-exclusive Pokémon in each game. Furthermore, {{p|Spiritomb}} may be caught in the [[Hallowed Tower]] in Diamond and Pearl, but only after the player speaks with other players in the [[Underground]] at least 32 times, requiring connections with other players through the wireless features of the Nintendo DS. In this generation, the [[Pokéwalker]] is the only other place where Spiritomb is available.

36 Pokémon from previous Generations can be obtained through the [[dual-slot mode]] in Diamond and Pearl, which requires inserting a core series Generation III game in the Nintendo DS system (16 from Generation I, 8 from Generation II, and 12 from Generation III). Additionally, any Pokémon caught in a core series Generation III game can be transferred over to Diamond and Pearl via [[Pal Park]], whereupon Pokémon cannot be sent to a Generation III game afterwards; prior to the release of later Generation IV games, these were the only ways to obtain {{p|Tangrowth}}, {{p|Electivire}}, {{p|Magmortar}}, and {{p|Gliscor}}, as their respective pre-[[Evolution]]s aren't available in either game otherwise. These methods aren't possible on the [[Nintendo DSi]] and [[Nintendo 3DS]] systems, which lack a GBA slot. All Pokémon available from the dual-slot mode are also available (without the dual-slot mode) in HeartGold or SoulSilver.

====Pokémon Platinum====
{{game|Platinum}} includes most of the Pokémon available in Diamond and Pearl, along with all of its methods required to obtain Pokémon in the game. 382 Pokémon are available without trading or connecting with another game, with only 12 Pokémon exclusive to Diamond and Pearl and the following 12 exclusive to Platinum: {{p|Tangela}}, {{p|Electabuzz}}, {{p|Magmar}}, {{p|Articuno}}, {{p|Zapdos}}, {{p|Moltres}}, {{p|Gligar}}, {{p|Elekid}}, {{p|Magby}}, {{p|Tangrowth}}, and {{p|Gliscor}}. As Magmar and Electabuzz can now be obtained, they can be traded with another game to obtain {{p|Magmortar}} and {{p|Electivire}}, adding up to 411 Pokémon available across Diamond, Pearl, and Platinum.

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====
427 Pokémon are available across {{game|HeartGold and SoulSilver|s}}. Most of the Generation I and II Pokémon are available in the game, except for the event-exclusive {{p|Celebi}} and {{p|Mew}}, while 117 Pokémon from Generation III and 61 Pokémon from Generation IV are also available; most of these Pokémon are obtained after entering the [[Hall of Fame]], with some of the cross-generational Evolutions from Generation IV being available before then. Together with Diamond, Pearl, and Platinum, this allows players to obtain nearly every single Pokémon created up to this point without requiring a Generation III game, the compatibility for which had been dropped from Nintendo DS models starting with the Nintendo DSi.

391 Pokémon are available in Pokémon HeartGold, while 389 Pokémon are available in SoulSilver, with each version having 19 and 21 Pokémon only found on the other version, respectively. 16 Pokémon are only obtained as a trade Evolution, and {{p|Rayquaza}} can be caught in the [[Embedded Tower]] in HeartGold and SoulSilver after the player trades with the opposite version to obtain a {{p|Kyogre}} or {{p|Groudon}}.

Despite their pre-Evolutions appearing in the game, {{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.

[[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. 21 Pokémon obtained from the Pokéwalker cannot be found normally in HeartGold and SoulSilver (13 from Generation III and 8 from Generation IV). However, all Pokémon from the Pokéwalker may be normally found in Pokémon Diamond, Pearl, or Platinum, so the Pokéwalker is not required to find any Pokémon in this generation.

[[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.

===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 {{B2W2}}, {{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====
In {{game|Black and White|s}}, 464 Pokémon are available by trading or connecting with both games. 150 Pokémon introduced in this Generation are available ({{p|Victini}}, {{p|Zorua}}, {{p|Zoroark}}, {{p|Keldeo}}, {{p|Meloetta}}, and {{p|Genesect}} are event-exclusive), while 314 Pokémon from previous Generations become available after obtaining the National Pokédex: 110 Pokémon from Generation I, 65 from Generation II, 86 from Generation III, and 53 from Generation IV.

340 Pokémon are available in Pokémon Black without connecting to another game, while 432 are available in Pokémon White, with 18 version exclusives and 6 trade Evolutions for each game. {{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}}.

Particularly, Pokémon White features [[White Forest]], a location featuring exclusive Pokémon that normally requires Pokémon White players to connect with Pokémon Black in order to obtain every single Pokémon in it; however, several of its [[evolutionary line]]s can be obtained without connecting to Pokémon Black if the player reaches White Forest within a certain amount of days after the save is first created. 92 Pokémon are potentially available in White Forest without trading or connecting with Pokémon Black: 29 from Generation I, 16 from Generation II, 35 from Generation III, and 12 from Generation IV, with 8 trade Evolutions for some of these Pokémon ({{p|Alakazam}}, {{p|Machamp}}, {{p|Gengar}}, {{p|Porygon2}}, {{p|Rhyperior}}, {{p|Electivire}}, {{p|Magmortar}}, and {{p|Porygon-Z}}) for a total of 100 Pokémon available in White Forest.

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====
{{B2W2}} together have all the non-event Pokémon from the second version of the Unova Pokédex (which was expanded to a total of [[List of Pokémon by Unova Pokédex number in Pokémon 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 first partner Pokémon 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 [[List of Pokémon by Hoenn Pokédex number in Generation 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 lines, 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 [[List of Pokémon by Alola Pokédex number in Pokémon Sun and Moon|302 Pokémon]] in the first pair of games and was expanded to [[List of Pokémon by Alola Pokédex number in Pokémon 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!====
{{main|Pokémon availability (Let's Go, Pikachu! and Let's Go, Eevee!)}}
{{LGPE}} are both compatible with 153 Pokémon species, being the first set of [[core series]] games to fully exclude Pokémon species from preceding games. There are three [[Mythical Pokémon]] ({{p|Mew}}, {{p|Meltan}}, and {{p|Melmetal}}) which are not found in-game but are available by other means. In addition, these games are compatible with the 18 [[Alolan form]]s and 15 Kanto [[Mega Evolution]]s available in Generation VII.

===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 [[List of game-based Pokémon distributions in Generation 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.

Unlike others of their species, {{p|Pikachu}}, {{p|Meowth}}, {{p|Eevee}}, and {{p|Duraludon}} with the [[Gigantamax]] Factor cannot be [[transfer]]red from [[Pokémon HOME]] to games other than {{g|Sword and Shield}}. Since these Pokémon are unable to [[evolution|evolve]] in Pokémon Sword and Shield, this is to prevent them from evolving in other games.

====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 lines.
* 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.
