Can Pikachu and Eevee evolve?
Your starter Eevee or Pikachu will not be able to evolve, but any Pokémon that you catch will. Keep in mind that since the game features first-generation Pokémon, the only available Eeveelutions will be Jolteon, Flareon and Vaporeon.
What is the point of having Eevee as a starter if you can't even evolve it. That's literally the whole point of Eevee.
