Zygarde, referred to as Z, is a legendary Pokemon residing in the Terminus Cave of Kalos which is also known as the Watcher. It could summon power from nature to itself, and is said to be capable of ceasing the endless battle between Xerneas and Yveltal. It was captured by Essentia at Anistar City in its vulnerable state while it was charging up itself, and later fell under Lysandre’s command. After Xerneas and Yveltal returned to their dormant states, it disintegrated into countless green squishy blobs.
