The Pokémon Company has officially revealed the silhouettes of the Hisuian final starter evolutions. They also posted a trailer to tease the reveal of these Pokémon forms.
You may have met Dartrix, Quilava, and Dewott in your other adventures. But you’ve never encountered their Hisui region Evolutions. You’ll be able to discover their evolved forms for yourself as you journey together in Pokémon Legends: Arceus.
