Every paired game release in Pokémon history has had version-exclusive Pokémon. Version-exclusive Pokémon cannot be found in every game in a 'set' of games, requiring the player to trade with players with other games in the set to complete their Pokédex. This page lists the version-exclusive Pokémon in FireRed and LeafGreen, and makes note of some other version-specific Pokémon attributes.
Several species of Pokémon are altogether unavailable without trading with other games. This list shows which Pokémon are only available in some (but not all) of FireRed and LeafGreen. This does not include Pokémon that evolve via trade, even though they are technically "unavailable without trading".
With the initial paired versions of a set of Pokémon games, it is usually the case that there are 'paired Pokémon' that are available in the same areas between the two games, but one Pokémon in the pair is exclusive to one game and the other is exclusive to the other game. The table below shows the paired Pokémon in FireRed and LeafGreen.

Some evolutions of Pokémon can only be obtained in the wild in one of FireRed or LeafGreen. This list shows which Pokémon are limited. The player can of course always evolve their pre-evolved form, so these Pokémon are not completely inaccessible.
