What is Eevee's National Pokédex number?

Eevee's National Pokédex number is 133. It is a Normal-type Pokémon introduced in Pokémon Red and Green and is known for its unusually broad evolutionary potential.

Eevee can evolve into several different species, including Vaporeon, Jolteon and Flareon in the first generation. Later games added Espeon, Umbreon, Leafeon, Glaceon and Sylveon. The exact evolution depends on items, friendship, location, time of day or other game-specific conditions.

The neighboring numbers are easy to mix up: Vaporeon is 134, Jolteon is 135 and Flareon is 136. Eevee's number is also distinct from its regional Pokédex positions, which can change between games and regions.
