First explored by Pokémon X and Y, the rare and powerful mega evolution mechanic will be part of a trainer’s toolbox in the upcoming Switch titles, Pokémon Let’s Go, Eevee! and Pokémon Let’s Go, Pikachu!

If a Pokémon’s trainer has the appropriate mega stone it can mega-evolve, but the change only happens during the course of one battle. The news comes our way via Japanese magazine CoroCoro, which shows the mega evolutions of Charizard, Blastoise, and Venusaur.  You can thank Pokémon fansite Serebii, who helped spread the word by quickly posting screens from the magazine to confirm the news.

Our Take
We’ve previously talked about the Let’s Go games in an effort to figure out questions such as, “what are they?” and “should we be excited?”

Deeper mechanics like mega evolutions point to a full-featured game, so this is good news for hardcore fans.
