You can get Pikachu and Eevee in Pokémon Sword and Shield, but lucky players will also be able to get unique versions of the Pokémon that can Gigantamax as well. If you are a fan of the series and have played Let’s Go Pikachu and Let’s Go Eevee, then you are in luck.
To get Gigantamax Eevee and Gignatamax Pikachu, you need to have played the relevant version of Let’s Go. Having a Let’s Go Pikachu save file on your Switch grants you a Pikachu who can Gigantamax, and the same applies to get the Gigantamax Eevee. Once you have a Let’s Go Eevee save file on your Switch, you can get an Eevee who can Gigantamax.
All you need to do is play through the game until you take the train from Wedgehurst, and arrive at the Meetup Spot at Wild Area Station. To the left of the turnstiles at the station, there’s a boy and a girl standing in the corner.
If you talk to the boy and have a Let’s Go Eevee save file, he gives you the Gigantamax Eevee. If you speak to the girl and have a Let’s Go Pikachu save file, she provides you with a Gignatamax Pikachu.
It’s important to note these Pokémon cannot evolve, but they have perfect six IVs in all stats. They will also have random natures, so every time you get them on a playthrough, the natures change.
Now you know how to get Gigantamax Eevee and Pikachu, they can help you win battles as you try to become a great Pokémon Trainer.
