Pokemon Let’s Go, Pikachu and Let’s Go Eevee takes place in the Kanto Region but that doesn’t mean that the Pokemon you will get to find is limited to that region. Luckily, there are certain Pokemon who managed to get into certain NPCs in the game that allow you to get them if you trade a specific Pokemon.
In the past Pokemon games, in-game trades have always been available for those who don’t have friends to trade Pokemon with. However, they are only limited to trading one copy. Apparently in Pokemon Let’s Go, Pikachu and Let’s Go Eevee, they can be done unlimited times as long as you have the Pokemon they want to trade with.
Here are the list of In-Game trades that are possible in Pokemon Let’s Go, Pikachu and Let’s Go, Eevee. Please note that the Pokemon listed here will be their Alola Form as they are from the Alola Region.
