Zygarde

Japanese name:

ジガルデ

Zygarde is a dual-type Dragon/Ground Legendary Pokémon introduced in Generation VI.
While it is not known to evolve into or from any other Pokémon, Zygarde has the following three Formes, which all retain its Dragon/Ground typing:
- Zygarde 10% Forme, one of the Formes introduced in Sun and Moon
- Zygarde 50% Forme, the Forme introduced in X and Y
- Zygarde Complete Forme, one of the Formes introduced in Sun and Moon
Along with these Formes are two basic components of Zygarde: Zygarde Cores, which act as the brains of Zygarde, and Zygarde Cells, which compose Zygarde's Formes and cannot think. Neither Zygarde Cores nor Zygarde Cells can use moves or are useful in battles by themselves. Both of these components were introduced in Pokémon Sun and Moon. They are stored inside the Zygarde Cube.
Zygarde 50% Forme was introduced in Pokémon X and Y. Zygarde Cell, Zygarde Core, Zygarde 10% Forme, and Zygarde Complete Forme were announced in the October 2015 issue of CoroCoro magazine. The remaining forms were introduced in Pokémon Sun and Moon. Prior to their appearance in Sun and Moon, Zygarde's other forms played an important role in the anime's XY&Z arc.
