Pokémon availability

Pokémon availability refers to the various means of obtaining in the .
==Overview==
In all core series games, some Pokémon may be 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 traded. Other methods to obtain Pokémon also exist, including breeding, in-game trades, receiving them as gift Pokémon, and s. Some Pokémon may not be available in a certain game, but may be traded from another game, or transferred from an earlier generation.
From Generation I until , 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 onwards, each new core series game has a limited pool of available Pokémon.
===First partner Pokémon===
The first partner Pokémon is given to the player at the start of their Pokémon journey. In most core series , the player can choose a -, -, or first partner Pokémon at level 5. At least one of the player's rivals or friends also has a first partner Pokémon, which may either have a type advantage or disadvantage over the player's depending on the game.
In and , the player instead receives the or as their first Pokémon.
===Wild Pokémon===
The player is able to find and several kinds of wild Pokémon in tall grass, caves, water, etc. The wild Pokémon can be caught using a Poké Ball.
===Version-exclusive Pokémon===
Some Pokémon are only found in one or two games within a particular set, to encourage trading between players. For example, between , appears only in Ruby, while 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===
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 Pokémon and in some cases Legendary Pokémon.
For instance, the player is able to choose between , , and as their first partner Pokémon in , . The player may also choose one of these Pokémon as a gift given by Professor Oak in , by Professor Sycamore in , and by Grand Oak in .
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===
Some Pokémon are permanently missable. For instance, prior to , 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===
In some cases, a Pokémon cannot be legitimately obtained as . 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.
