Pokémon Let's Go, Pikachu & Let's Go, Eevee

In-Game Trades

Like past Pokémon games, there are numerous characters that will do an in-game trade, offering you a Pokémon in exchange for another. However, Pokémon Let's Go, Pikachu! & Let's Go, Eevee! changes this somewhat and has it so these trades can be repeated as much as you want. This is due to the fact that these trades offer you the Alola Forms of Kanto Pokémon
