From Bulbapedia, the community-driven Pokémon encyclopedia.
Version-exclusive Pokémon are Pokémon that are only found in one or two games in a single generation, to encourage trading between multiple players. For instance, in the original Pokémon Red, Bellsprout was absent but appeared in Pokémon Green (Pokémon Blue outside Japan). Version-exclusive Pokémon usually complement each other in design, type, as well as location of appearance in the wild.
It is typical for several evolutionary families of Pokémon to be version exclusives in the first two games of a generation, and then, in the third version, some version-exclusives from the first two games will be obtainable, while others are not, and some Pokémon that were obtainable in both of the first two games will be unobtainable. For example, the Weedle and Koffing families were obtainable in both Pokémon Red and Blue, but unobtainable in Pokémon Yellow.
Below is a list of Pokémon exclusive to games. This list does not take note of Pokémon exclusive between Generation III Kanto and Hoenn games, simply because there are too many Pokémon that are native to each individual region to list; a better indicator of those Pokémon which are missing from each region would be the Kanto Pokédex and Hoenn Pokédex. However, even this does not take Generation II Pokémon into account, since the vast majority thereof is only listed in the National Pokédex of those games. Furthermore, a list of Pokémon missing from the Generation III GameCube games, Pokémon Colosseum and Pokémon XD, is far too long to be included in this context.
Take note that the Pokémon listed below are from that particular game, and will need to be traded from a game within the same generation that does not list them. Therefore, Pokémon obtainable in Generation II by trading with Generation I, Pokémon obtainable in Generation IV by utilizing GBA games, legendary Pokémon and starter Pokémon and Pokémon obtained from attending promotional events, are all excluded from the following list.
It is of relevant note that in Pokémon Diamond and Pearl, most of the version exclusives of the Generation III games can be caught in the wild by inserting one of the GBA games into the DS. In Pokémon XD, the seven Emerald-absent Pokémon are all obtainable, thus eliminating the need in trading with either Pokémon Ruby or Pokémon Sapphire.
In the main series games
The Japanese Blue Version does not have the same Pokémon distribution as the English Blue Version. The English Blue's Pokémon distribution is in fact the same as that of the Japanese Green. Listed below under the "Blue" header is the Japanese Blue.
Phanpy, Donphan, Teddiursa, and Ursaring are available in the opposite paired version in Japan that they are internationally, with the first two in the Japanese Gold and the latter two in the Japanese Silver. However, this change does not occur in HeartGold and SoulSilver's international release.
The following are only found in Pokémon Emerald, once the National Pokédex is obtained:
- When Genesect is holding a Drive, the light on its cannon changes color. The Burn and Shock Drives are exclusive to Black, while the Douse and Chill Drives are exclusive to White.
- While Cottonee and Petilil are only available in the wild in Black and White respectively, there is an in-game trade in Nacrene City for the Pokémon which is exclusive to the other game. By extension, this also allows Whimsicott and Lilligant to be obtained in the versions they are otherwise unobtainable in.
- While Volbeat and Illumise are only available in the wild in Black and White respectively, Illumise can breed with any male Pokémon in the Bug Egg Group, Human-Like Egg Group or Ditto to produce Eggs that have an 50% chance of hatching into Volbeat. Likewise, breeding Volbeat with Ditto may produce Illumise Eggs.
- Wild Huntail are exclusive to Black, while wild Gorebyss are exclusive to White, but Clamperl can be found and evolved in both games.
- Metapod, Butterfree, Misdreavus and Poochyena are exclusive to White, while Murkrow and Houndour are exclusive to Black; however, these Pokémon are available in the Pokémon Dream World.
The following Pokémon can only be found in White Forest, or can only be obtained by breeding or evolving a Pokémon caught in White Forest, which is exclusive to Pokémon White:
- These Pokémon's fully evolved forms can be encountered and battled in Black City, which is exclusive to Pokémon Black, but are uncatchable there. Also, each game has a limited number of Pokémon species and need to connect to other players in order to increase that number. Only the first forms are obtainable in White Forest, and only at level five.
- Pidgey, Nidoran♀, Nidoran♂, Abra, Machop, Magnemite, Gastly, Rhyhorn, Mareep, Elekid, Magby, Lotad, Surskit, Marill, Ralts, Trapinch, Corphish, Bagon, Starly, and Shinx are also obtainable from the Pokémon Dream World, therefore enabling them, their pre-evolutions, and evolutions to be acquired in Pokémon Black without trading.
- Similarly to Black and White, while Cottonee and Petilil are unavailable in wild in White 2 and Black 2, respectively, an in-game trade on Route 4 allows to obtain the one that is exclusive to the other version. It also allows to obtain Whimsicott and Lilligant in version where they're otherwise unavailable.
- Akin to previous games, VolbeatB2 or IllumiseW2 swarms on Route 3. Illumise can breed with any male Pokémon in the Bug Egg Group, Human-Like Egg Group or Ditto to produce Eggs that have an 50% chance of hatching into Volbeat. Likewise, breeding Volbeat with Ditto may produce Illumise Eggs.
- While Route 12 and Lostlorn Forest have wild Pinsir in White 2 and wild Heracross in Black 2 (without the other one), in the forest's Hidden Grotto (which isn't marked by Pokédex), both can appear, no matter the version.
- As in previous games, wild Huntail are exclusive to Black 2, while wild Gorebyss are exclusive to White 2, but Clamperl can be found and evolved in both games.
- When Genesect is holding a Drive, the light on its cannon changes color. The Burn and Shock Drives are exclusive to Black 2, while the Douse and Chill Drives are exclusive to White 2, similar to original games.
- White 2's counterpart to the Shiny Gible given away by Benga is a Shiny Dratini; however, Dratini's evolutionary line can be caught in the wild in both versions, whereas the Gible line cannot.
- Normally unavailable, Regice and Registeel can be caught in the Black 2 and White 2, respectively, after trading respective keys from game which has unlocked them. Initially, Regice's key is unlocked in White 2, and Registeel's in Black 2.
In the spin-off games
As trading is not possible between these games, the listed Pokémon will appear in the wild only when a rescue mission involving the Pokémon is completed. This requires a Wonder Mail Code from the alternate version, in which the Pokémon is normally found.
- Porygon2, while only available in wild in Blue Rescue Team (without Wonder Mail mission), it is also available via evolving Porygon in Red Rescue Team.
In the anime
For the first time in the anime's history, two different versions of a movie were released. Victini and Zekrom features the Victory Pokémon Victini and the Deep Black Pokémon Zekrom, while Victini and Reshiram features Victini and the Vast White Pokémon, Reshiram. Much like the games, there are Pokémon that are exclusive to each movie.
- Ash's Tranquill appears in both versions of M14, however, in Victini and Zekrom, wild Tranquill also appear in the intro.
- Blitzle appears in both versions of M14, but under different circumstances. In Victini and Reshiram, wild Blitzle appear in the intro, while in Victini and Zekrom, one appears under the ownership of Luisa.
- Golurk appears in both versions of M14 under the ownership of Juanita. However, it is Shiny in Victini and Reshiram.
- Hydreigon appears in both versions of M14 under the ownership of Carlita. However, it is Shiny in Victini and Zekrom.
- Due to a large number of wild Pokémon that can only be caught on White Forest which is an area that is exclusive only to Pokémon White, Pokémon White has the largest number of version-exclusive Pokémon of any Pokémon game to date.
