It's that time again - CoroCoro has leaked, and with it comes some brand new information on Zygarde and the Pokémon anime. Firstly, the next "series" of the Pokémon anime has been revealed to be called "Pokémon XY & Z" in Japan, and will premiere October 29th. It will contain a Greninja with Satoshi/Ash's colourings.
Secondly, we have new information on three new Zygarde formes, which you can see in the middle-left of the image above:
For the uninitiated, CoroCoro is a Japanese monthly magazine that often reveals new Pokémon information - as such, all names given here are the Japanese names and may change when The Pokémon Company International reveals this info themselves.
- The blob teased in last month's CoroCoro is Zygarde's Cell Form (alternately translated as Core Form), and serves as the core for its other forms.
- A totally new dog-like forme is Zygarde's 10% Forme - it focuses on speed, and has been said to have "sharp teeth".
- Zygarde's existing forme as of XY and ORAS is now called "50% Forme".
- The Pokémon shown in the 2016 movie teaser is Zygarde's "Parfect Forme", and is said to exceed Xerneas and Zygarde in power. It is 4.5m tall, 610kg, and retains Zygarde 50% Forme's Dragon/Ground typing.
So, to recap the rumour mill for Pokémon Z - as of now as we dip into speculation: Because of this reveal, we believe the next main-series Pokémon game to be Pokémon Z rather than Pokémon X2 and Y2. Either way, the next Pokémon game is pretty definitely set in Kalos.
All sources point to the game being released in early-to-mid 2016, especially the official timeline revealed with Pokémon GO!. That means the games themselves will be revealed reasonably soon. I would personally suggest a full game announcement will come in next month's CoroCoro, if The Pokémon Company International don't get there sooner.
