A host of new leaks and hints surrounding the release of Pokemon Z have been making rounds online.The latest of which is Gen 6 Pokemon Zygarde spotted in a new Pokemon XY Movie 'Mega Evolution IV' special trailer and a most recent leak suggesting a possible announcement of release details happening this November.

Yibada reports that the said trailer which lasted for 30 seconds has featured Pokemon Mega-Charizard X, Mega-Venusaur, Mega-Bannette, Mega-Alakazam, and Mega-Houndoom. What makes it more interesting to fans, though, is that the green blob Pokemon alongside the Kalos grass-type starter Pokemon Chespin also appeared and spotted in the teaser clip where rumors suggest this little Pokemon has a possible link to Zygarde.

Hardcore and seasoned Pokemon fans are aware that Zygarde is the 3rd legendary Pokemon of the Kalos region other than Xerneas and Yveltal. It appears to have serpent-like body with green, black, and white hexagonal pattern and as per iDigitalTimes, the hexagon pattern of the blob-like creatures could likely be 'shed fragments' of Zygarde's skin which turns into a new and alive Pokemon.

The said movie special trailer revealed a silhouette of a never-before-seen creature assumed to be a new Pokemon form and fans believe that the mystery Pokemon is Zygarde's mega-evolution. This could mean that Zygarde will be the second legendary Pokemon to have a mega-evolution after Mewtwo. 

Movie Pilot noted that the Mega Evolution IV movie special trailer hints the release of Pokemon Z as Nintendo's next title to succeed Pokemon X and Y.  

Meanwhile, a new leak in Japan has also surfaced online pointing to a possible announcement of release details for Pokémon Z, courtesy of Joe Merrick who known as a credible source and webmaster of Serebii. Merrick shared via Tiwttder that a merchandise sell sheet contains a clue of a new Pokémon.
