'Pokemon Z' Release Date News: Legendary Zygarde Form Plus 'Ash Greninja' Detailed [PHOTOS]

UPDATE: A video clip has been revealed showing the new Zygarde forms and Ash-Greninja in action. Check it out below.

Following a tease in CoroCoro Magazine, the official reveal of the Zygarde forms have arrived. The forms will keep their names but Zygarde Perfect Forme will be dubbed Zygarde Complete Forme in the U.S., reports Serebii. There are four different forms that Zygarde will have that range from a tiny blog, a canine form and a towering monstrous form.

First up is Zygarde Cell. This stage has been identified as the single cells that make up Zygarde says the official pokémon website. They do not possess any will or thought processes. Cells are found scattered throughout the region. They can't use any moves and researchers are debating if they should even be called pokémon.

Then there is Zygarde Core and at this stage Zygarde is a little more than a part of the pokémon's brain. Unlike the Cells, the Cores are self-aware and can communicate with Cells and other Cores using telepathy. When changes occur in the region's ecosystem, the Cores have been known to take action.

Zygarde 10% Forme is next and in this form the pokémon takes when it gathers 10 percent of the Cells nearby. The Zygarde 10% Forme is capable of traveling over 60 mph and it can defeat enemies with its sharp fangs and its incredible speed.

And lastly we have the Zygarde Complete Forme. This is the form the pokémon takes when the Core gathers 100 percent of the Cells. When the ecosystem is under attack and the Core concludes that the 50 percent form can't handle it, the Core takes on the Complete Forme. Its power is said to be greater than that of the legendary pokémon Xerneas and Yveltal.

Meanwhile, the "Ash Greninja" was also detailed and we learned that the pokémon takes this new form when the bond between it and Ash is raised to the limit. The strength of their bond changes Greninja's appearance, and it takes on the characteristic look of Ash's attire. This phenomenon is also said to have happened just once several hundred years ago in the Kalos region, but the entire change is still clouded in mystery.

The new 'mon will be featured in the upcoming "Pokémon XY & Z" anime, which is said to arrive Oct. 29. Until then check out the all-new Zygarde forms along with the Ash-Greninja below:
