Purchase: Celadon Game Corner
This page lists the highest possible level at which Pokémon can be obtained in Red, Green, Blue, and Yellow. Use the radio buttons above to switch between the Japanese games (RGBY) and the international games (RBY).
Only Pokémon that can be found in the wild, as gifts, or via purchasing are listed here, since the player can obviously evolve a Pokémon or complete an in-game trade at any level.
