A Z-Crystal (Ｚクリスタル Z Kurisutaru in Japanese) is a kind of object introduced in Generation VII which is used to activate a Z-Move. It helps Pokémon use the corresponding Z-Move when equipped in one, as long as it knows a move of the same type. One Z-Crystal can be used as many times and on many Pokémon as one wishes. The Z-Crystals work with the Z-Ring.
