The Pokemon Company has published the first trailer, screenshots, and details for Master Trainers in Pokemon Let’s GO Pikachu/Eevee.

Master Trainers are scattered across the Kanto region. Each Master Trainer is specialized for a specific Pokemon – defeat them to gain their title.

Check out everything about Master Trainers below.

Once you become the Pokémon League Champion, your journey is far from over! After earning that coveted title, you will find new special Trainers scattered throughout the Kanto region. These are the Master Trainers, and each of them is considered the strongest Trainer for a specific Pokémon. That’s right—there’s a Master Trainer for every Pokémon in the Kanto region!

Master Trainers are always thinking about their favorite Pokémon, so you can spot them at a glance. The icon of the Pokémon they favor is displayed above their heads, and the color of their attire is different than other Trainers, too.

Some Master Trainers will have a simple request for you, but most of them will want to battle! The only catch is that they will only battle against the species of Pokémon they love. You’ll need to train up each of your Pokémon to take on these tough challengers. Because these Master Trainer battles are true tests of you and your Pokémon’s strength, neither you nor the Master Trainer will be able to use items during the match.

Best the Master Trainers in battle to earn their title, proving that you’re also a master of their favorite species. The titles you’ve earned can even be displayed in-game during Link Battles so that your friends can admire your skills. Show what a devoted Trainer you are by challenging all the Master Trainers!
