Zygarde Forms and More

The flat thingy is Zygarde Cell (Type unknown)
The green thingy we already saw is Zygarde Core (Type unknown)
The dog thing is Zygarde 10%, meaning it can be charged somehow (Type unknown)
The Zygarde we know and love is Zygarde 50%
The shadow from the trailer is Zygarde Perfect Forme, it is still Dragon/Ground
Ash's Noibat evolves into a Noivern.
Ash's Frogadier evolves into a Greninja and gets a custom look Ash-Greninja and it looks like Ash
Ash's Sceptile most likely returns to serve as the Grass type in the team and probably as the Mega too
The new anime is called XY and Z
Mega Act 4 comes on October 29

My Opinion?
It's cool, I have no problem with these reveals. I hope we see more Zygarde forms but I doubt it. Ash Greninja looks cool, I think it's just a Protean thing, it's not a Mega. I'm glad we are getting Noivern.
