Zygarde (ジガルデ) is a dual type Dragon/Ground Legendary Pokémon. It is known to posses multiple forms. In Super Smash Flash 2, Zygarde appears as one of the Pokémon that can be released from a Poké Ball or Master Ball to aid the player.
Zygarde 50% Forme has a serpent-like body with a green and black pattern on it. There are black frills on the back of its head like a frilled lizard. Its eyes comprise four green hexagons like the compound eyes of an insect. More green hexagons are on the front and back of its frills. The hexagons on its eyes and frills can glow. Its tail is flat and is black on top and green on the bottom. Its tail ends with five separate green tendrils. It is said to monitor the ecosystem, and if the ecosystem falls into disarray, it appears and reveals its power.
Zygarde Complete Forme has a large, humanoid body with a long tail similar to Zygarde 50% Forme's body. It has two similar appendages protruding from each of its shoulders. On each of these appendages is a hexagon and an undulating pattern; on its right side, these are colored blue, and on its left side they are colored red. It has multiple white protrusions on its body: three on each hand, one on each knee, and one and the front of its feet. Its torso is composed of a lower abdomen and an upper chest. The abdomen has a vertical, hexagonal pattern upon it with two thin, white, and vertical marks on either side. Upon the chest is thin, zig-zagging opening which fades between five colors: red, orange, white, cyan, and blue. The chest can open, revealing five cores of each color. Above this opening are two large green, hexagonal marks. Atop its chest is its crown-shaped head. It has three white hexagonal marks above four horizontal ones, the uppermost white one having a very thin diamond shape through it, and the lower two being eyes. Directly above the third mark is a final green hexagon. Surrounding the head are triangular protrusions connected by another upside-down triangle which is jagged at the top. Zygarde Complete Forme is said to exceed both Xerneas and Yveltal in power, possessing 100% of its total cells. Zygarde only enters Complete Forme when the ecosystem is under threat and the Zygarde Core believes it is outmatched.
In Super Smash Flash 2
As stated above, Zygarde can be released from a Poké Ball or Master Ball in Super Smash Flash 2. Once released, it uses Land's Wrath, which will cause fissures on the stage or platform.
