Question: what eeveelutions are in pokemon let's go?
Answer: You gotta evolve Eevee! Whether you picked up Pokémon Let's Go Pikachu or Pokémon Let's Go Eevee, you can add your very own Eevee to your Pokédex and you can evolve it into one of the three elemental types; water, fire, or thunder. Once evolved, Eevee will become either Flareon, Jolteon, or Vaporeon.
