Niantic revealed the details of the upcoming Trainer Battle feature for the Pokémon GO smartphone game on Tuesday.
The game began releasing Pokémon that originally appeared in the Sinnoh region, which debuted in the Pokémon Diamond and Pokémon Pearl games, in October.
The game revealed the all-new Mythical Pokémon Meltan in September, and the Pokémon became obtainable with the release of the Pokémon: Let’s Go, Pikachu! and Pokémon: Let’s Go, Eevee!
Players will also be able to use new Protect Shields during Trainer Battles, but only a limited number will be available in each battle.
