A new element has been introduced into the Pokémon battles in Pokémon Sun and Pokémon Moon: Z-Moves. Z-Moves are moves of great power that can only be used once per battle. When the Trainer and Pokémon’s wishes resonate with each other, and both release their full power together—the result is the explosive force of a Z-Move! All Pokémon can use Z-Moves to perform mightily in battle!
The Z-Ring fits on a Trainer’s arm, and Z-Crystals are set into it. If a Pokémon holds the same variety of Z-Crystal, the two will be able to resonate with one another. Crystals that correspond to each Pokémon type have been found in the Alola region.
There are two conditions for performing Z-Moves: a Pokémon must learn a move of the same type as a Z-Crystal, and it must be holding the corresponding Z-Crystal.
When you see these moves in action in the game, each overwhelmingly powerful move will be on full display, filling the entire screen!
