Starter Pokémon
In Pokémon Blue and Red, the starter creatures that are available to you remain the same. You’re given the choice between Charmander, Bulbasaur, and Squirtle and whichever one you choose, your rival will choose its weakness. For example, if you choose the fire-type Charmander, your rival will choose the water-type Squirtle.
If you pick up Yellow, however, you will be given Pikachu from the start and do not get the choice of the other three Pokémon. Your little electric mouse Pokémon will follow you around Kanto and you can speak to him often to see how your relationship with the creature is. At the start you’ll find that Pikachu isn’t very happy with you, however, just like in the anime, it’ll become your best friend in due time.
As for the starter Pokémon from Red and Blue, you will acquire them from other Pokémon trainers throughout your adventure in Yellow. Your rival will also be given an Eevee and the evolution that your rival chooses for their cute Pokémon will be dependent on your success or failures in defeating him during your adventure.
