Pokémon availability (Let's Go, Pikachu! and Let's Go, Eevee!)

Pokémon: Let's Go, Pikachu! and Let's Go, Eevee! are compatible with just 153 , making them the first set of core series games to fully exclude Pokémon species from preceding games. They feature three Mythical Pokémon (, , and ) which are not found in-game but are available by other means. In addition, these games are compatible with the 18 Alolan forms and the 15 Kanto Mega Evolutions.
==Availability==
The first 150 species in the Kanto Pokédex are obtainable in-game, subject to 4 trade Evolutions and 11 version-exclusives each—which would normally necessitate trading between versions for Pokédex completion, but upon reaching Fuchsia City, these 150 can also be transferred (one-way) into the games from via the GO Park. Using this transfer method, and become obtainable. And starting from 's fifth anniversary, over six years after the games' releases, Meltan (as a Shiny) can also be obtained from HOME, where it is available as a gift for completing the Kanto Pokédex. The other Mythical Pokémon, , is exclusively obtained from the Poké Ball Plus. Only one Mew is obtainable per Poké Ball Plus; and Meltan is only able to evolve into Melmetal within Pokémon GO.
All of the 150 except for are repeatedly obtainable in-game when combining both versions, although some require reviving Cerulean Cave Fossils (of , or ), or by catching rare spawns. These rare spawns, which allow for exclusive in-game event Pokémon to be recaptured, include the Kanto Pokémon (, , and ), the Fighting Dojo prizes ( and )—in addition to , , , and (the latter not being rare in Cerulean Cave). The remaining rare spawns, which are in the sky and only unlocked after becoming , consist of , , and the legendary birds (, , and ). Without Catch Combos, these rare spawns generate at a combined 1 in 200 chance—the exception is the legendary birds, which instead have a 1 in 2000 combined chance of being generated.https://x.com/Sibuna_Switch/status/1538721114066673665
Most species are catchable in Let's Go, Pikachu! (LGP) and Let's Go, Eevee! (LGE), but 23 require evolving the previous evolutionary stage. The species that require Evolution include the 5 remaining Kanto Evolutions (, , , , and ); the 4 Let's Go partner Evolutions (, , , and ); 4 version-exclusives ( and for LGE, and and for LGP); the 4 trade Evolutions (, , and ); the 2 Fossil Evolutions ( and ); and finally, 4 other Evolutions (, , and ). Additionally, is not catchable in LGE and is not catchable in LGP.
===Variant availability===
 combined have a total of 212 forms (210 compatible per version), consisting of the 186 original, Alolan, and Mega Evolved forms; 22 as a result of gender differences (for 208 Pokédex forms); and 2 partner forms with each of their gender differences.
The 18 Alolan forms are exclusively obtained via a set of in-game trades. The Alolan forms of , , , , , , and are obtained by the Evolution of the Alolan , , , , , and forms received via trading, respectively. The remaining forms received via in-game trade are Alolan , and .
 and 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.
All Pokémon forms can be obtained Shiny except for , and and . Apart from partner Pikachu and Eevee, which are both scale-locked (4 different scalars within the AV range), all forms can be obtained in any size: XS, S, AV, L, or XL.
Each version has 16 version-exclusive forms (or 17 including the partner's gender difference); but in addition, Let's Go, Pikachu! has 3 version-exclusive gender differences (, , and ). Of the in-game trades and their Evolutions, Alolan , , and are exclusive to Let's Go, Pikachu!, while Alolan , , and are exclusive to Let's Go, Eevee!
Combing both versions, a total of 346 gender-form combinations are possible. 158 forms, consisting of 126 Species, 18 Alolan forms, 12 Mega Evolutions and both partner forms, can be both female and male, amounting to 316 combinations after doubling. The remaining combinations are from 30 single gender forms, including 17 gender unknown forms (, , , , , , , , , , , , Mega Mewtwo X, Mega Mewtwo Y, , , and ), 6 male-only forms (, , , , , and ), and 7 female-only forms (, , , , , Mega Kangaskhan, and ).
===Level availability===
All but two Pokémon, and , can be obtained in-game at level 50 or below. Both, along with (which is obtained below level 50 by evolving ), are exclusive to Cerulean Cave. Golduck and Lickitung can be caught as low as level 51, while Mewtwo is only available to be caught at level 70. Regarding the other Legendary Pokémon, the legendary birds (, , and ) are all obtained at level 50 in their in-game event locations. And although only evolves from starting at level 55, a Dragonite (or even a legendary bird) as low as level 3 can be caught from a rare flying spawn in the post-game.
At level 70, Mewtwo is the highest-level encounter. Otherwise, level 57 is the highest level for wild Pokémon, occurring for the Cerulean Cave or rare flying spawns while a lure is in effect. When one is not in effect, they can spawn as high as level 56.
Level 1 Pokémon cannot be obtained except via transferring from Pokémon GO (or Poké Ball Plus in the case of ). This is because no breeding is present in the game, and the fact the lowest level wild Pokémon, such as and , are only encountered at level 3 or above.

:See Also: Appendix:Let's Go, Pikachu! and Let's Go, Eevee! walkthrough
The availability of forms in order of places visited in Let's Go, Pikachu! and Let's Go, Eevee! is shown below, counting up to 209 forms, which is the total number of obtainable non-Shiny forms on a single file. It shows Pokémon evolving at the earliest location and also assumes the player trades the same Pokémon to the complementing version for trade Evolutions.
* Many of the locations can be travelled through in different orders. The order mostly follows the walkthrough, with a different order once the player obtains Sea Skim in Fuchsia City.
* The (All Transfers) totals include , and . Subtracting one from the total after Poké Ball Plus and up to two after GO Park allows for the calculation of totals excluding them.
* The totals before "or" are from Let's Go, Pikachu! and the totals after "or" are from Let's Go Eevee!
* Several Pokémon are initially obtained only once when combining both versions and/or there is initially only 1 specimen for 2 evolutionary stages. The affected Pokémon are /, /, / and ///. A (-n) following the totals indicates the magnitude of the imbalance.
* Pokémon with gender differences are represented by a GD next to their sprites, stone Evolutions by SE, trade Evolutions by TE, the Alolan form trades by AT, a single request reward by SRR, special encounters by SP, and gender unknown by ⚪︎.
* Pokémon obtained via Evolution have a darker background, while Pokémon previously listed are in the reddish background.
* A Gym Badge or Champion Ribbon below the text of the location indicates the Gym or Elite Four challenge is intended to happen after collecting the Pokémon in that location.

====Evolved Pokémon in the wild later====
The availability of evolved Pokémon in the wild at their earliest locations is shown below, excluding those that already appear in the same earliest location as their non-evolved counterparts. Catching these Pokémon can save time with leveling up or prevent the using up of an Evolution stone. There are 28 of these species, with 3 version-exclusives each. 7 of them have gender differences, with 3 being exclusive to Let's Go, Pikachu! The remaining 6 in-game event Pokémon that can be recaptured are also included (with a darker background).

===Pokémon GO and HOME interaction===
The games are incompatible with Pokémon Bank, but you can instead transfer Pokémon from the games into Pokémon HOME. However, once a Pokémon is transferred from HOME to a Generation VIII or Generation IX game, it can no longer be transferred into 
No Ribbons are present in the games, but Pokémon GO origin marks are. All compatible Pokémon species except , as well as all Alolan forms, can be transferred from and thus possess the Pokémon GO origin mark. After Pokémon are transferred into from the games, those without a Pokémon GO origin mark will gain a Let's Go origin mark instead.
* As of Generation IX, 175 Pokémon species and 194 forms (excluding Shiny Mew) can have the Let's Go origin mark in HOME. In addition to the 151 Generation I species, , and 18 Alolan forms, a further 23 species and 1 additional form not compatible with Let's Go, Pikachu! or Eevee! can be obtained via Evolution in later games.
** Version 1.0.0 of made 8 of the then 21 Kanto-originated cross-generational Evolutions (, , , , , , , and ), along with   Weezing, obtainable with the Let's Go origin mark.
** Version 1.2.0 (The Isle of Armor) enabled 10 more to be obtained with the Let's Go origin mark: , , , , , , , , , and .
** Version 1.3.0 (The Crown Tundra) made the remaining 3 available with the Let's Go origin mark: , , and .
** introduced , with HOME Version 2.0.0 enabling transferring so it could be obtained with the Let's Go origin mark.
** introduced , with HOME Version 3.0.0 enabling transferring so it could be obtained with the Let's Go origin mark.
** introduced Shiny with the Let's Go origin mark as a gift on its fifth anniversary for completing the Kanto Pokédex—that is, for collecting the first 150 Pokémon species with Let's Go origin marks in HOME. Additionally, a Meltan with the Let's Go origin mark was distributed to celebrate the Chinese release of Let's Go, Pikachu! and Let's Go, Eevee!, exclusively to games with Simplified Chinese as its origin language.
Storing 25 of a Pokémon species or Alolan form (except Mew) in GO Park enables a mini-game called Play Yard for that species or Alolan form. Since there are only 1000 storage spaces for Pokémon (mirroring regular storage), that means only 40 out of 170 possible play yards can simultaneously exist on one save file.
In , as part of its 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 into , 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 Let's Go, Pikachu! and Let's Go, Eevee! has less than a 1 in 25 million chance to occur with the highest Catch Combo—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.
