Zygarde is a Pokémon whose form depends on the percentage of its Cores and Cells gathered together. The Zygarde Cores are the brain of the Zygarde, and a Zygarde may contain one or five Cores. A Zygarde Core is a small, green Pokémon with a gelatinous body. It has a large, round head with a beak-shaped protrusion on the front, a thin, hook-shaped tail, and a red hexagon suspended in its body. Within its head is a single eye with a black pupil; beside this eye is another white oval that may be a second eye. As seen in the anime, Zygarde Cores are capable of absorbing sunlight to regain their strength, can speak telepathically, and use the Cells to observe the ecosystem. Zygarde Cells make up every other part of Zygarde and appear nearly identical to the Zygarde Core. Unlike the Core, it has a flat body and head. It has a green pupil, a simpler, unhooked tail, and has a darker green, more elongated hexagon within its midsection.
Zygarde 10% Forme has a relatively small canine body. It is primarily black with a green collar and a leash-like extension on its neck. Additional green markings include: two hexagon markings on its chest, a small hexagon over each eye, the area around its mouth, and its front left paw. There is an elongated, red hexagon marking attached to the collar marking. Its eyes are white hexagons with no discernible pupils and there is a thin, white line on its forehead. On each of its legs are hexagonal extensions: two on the back of each elbow, one behind each knee, and two on each hip. One of the hip extensions is longer than the other on each hip. Zygarde 10% Forme also has razor-sharp teeth.
Zygarde 50% Forme has a serpentine body with green and black markings. Most of its back, head, and neck are black, while the underbelly and the tip of its tail are green. Its eyes are made of four green hexagons, similar to an insect with compound eyes, and there is a thin, white line down the center of its face. Across the back of its neck is a large frill made of five long, flat protrusions that each have two small, green hexagons on them. There are three short tendrils on either side of its chest; they are black on the right and green on the left. Its tail also ends in five tendrils. It has many small, green hexagon markings on its body capable of glowing.
Zygarde Complete Forme has a large, humanoid body with a long tail similar to Zygarde 50% Forme's body. There are several flat protrusions around its head and triangular protrusions around its neck. These protrusions create a crown-shape. On its face are three white hexagonal marks: one in the middle of its forehead with a line through it and two that act as eyes. There are an additional five green hexagons on its face: four along the bottom and one in the middle of a short protrusion on top. Each shoulder has two serpentine wings protruding from it. The wings all have an undulating pattern and a hexagon near the tip: blue on the right side and red on the left. There are multiple white protrusions on its body: three on each hand acting as claws, one on each knee, and one and the front of each foot. Additionally, there are green hexagons surrounding its wrists and two under the white protrusions on its knees and feet. Its abdomen has a vertical, hexagonal pattern with a thin, white line on either side. Across its chest is a thin, zigzagging opening that 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.
Zygarde cells tend to be scattered around the region while the Core remains in watch, usually living in caves. Zygarde's Cores and Cells do not have the power to battle alone and can only fight when combined to form Zygarde. The Cores have their own will and are sometimes able to act on their own, while the Cells form the rest of Zygarde's body and are only able to act on the Core's orders.[1]
10% Zygarde is created when a Zygarde core combines with only 10% of the total Zygarde Cells. 10% Zygarde Forme is skilled at close range combat. It is also capable of running at speeds greater than 60 miles per hour (100 kilometers per hour). A single Core acts as the brain for the 10% form. This allows it to take action separately from Zygarde's 50% Forme, which comprises its main body, for a short time before separating.[2]
The 50% Forme of Zygarde is formed from half of its Cores and Cells reuniting. Zygarde is thought to monitor those who destroy the ecosystem from deep within its cave. This form of Zygarde is known to be both ruthless and mercilessly destroying anyone who stand it its way. Should the region's ecosystem fall into disarray, it will appear and reveal its power. This power is Zygarde changing into the powerful Complete Forme. As seen in the anime, Zygarde can summon and control massive roots, which it can use to attack and cover areas.
The Complete Forme of Zygarde is formed when all 100% of its Cells And Cores come together. Zygarde Complete Forme contains separate Cores for each of its wings and its tail. In this case, each Core can make decisions and act independently of the others.[3] Possessing all of its total cells, Zygarde Complete Forme is said to exceed both Xerneas and Yveltal in power. The opening on its chest can radiate enough energy to destroy anything around it. This form only appears to neutralize threats to the ecosystems or should anything happen to its other two counterparts.
Zygarde is the only known Pokémon capable of learning the moves Land's Wrath, Thousand Arrows, Thousand Waves, and Core Enforcer.
