Pokemon Let’s Go Eevee and Pikachu differ from their predecessors in the way they handle your original starter. Instead of selecting one among many, you are gifted one of the two titular characters, depending on which version you purchased. This decision then locks that Pokemon to your character, marking them as your friend and companion throughout your Kanto journey. But, this special connection has left many players with one burning question. Can you evolve Eevee and Pikachu in Pokemon Let’s Go?
The answer is actually a bit complicated. For one, the answer is “no”. The Eevee and Pikachu that you get at the beginning of the game cannot evolve. So you can’t buy Pokemon Let’s Go Eevee and end up with your own special Flareon, for example. The Eevee you get at the beginning of the game will be an Eevee at the end of the game, no matter what you do.
However, these are not the only Eevee and Pikachu in Pokemon Let’s Go. Within both versions of the game you can catch new and different versions of these characters, all of which can be evolved into their later forms. So Jolteon, Flareon, and Vaporeon are all there, and so is Raichu.
