Question: can eevee evolve into espeon in pokemon let's go?
Answer: There's one thing they can't do though: evolve. Yep, that's right, just like in Pokémon Yellow, you can't evolve your chosen critter at all. Normally, Pikachu evolves into Raichu, and Eevee can be evolved into Flareon, Jolteon, or Vaporeon, depending on which elemental evolution stone you use.
