Definately seeing the similarity between Ash-Greninja to Eternal Flower Floette here. It raises a few questions thouth. For example, why not Pikachu, is it because hes NFE? Are they hinting at future Mega Evos for the Kalos starters? Could greninja be stuck in some sort of awkward transition between learning how to mega evolve? Will we eventually see Serena-Delphox, or is this something exclusive to Greninja for promotion aka Spiky-Eared Pichu?
Id also like to point out that the Greninja also has the same red-black color add-on as AZ Floette does. It may just be coincidence but still worth noting.
I feel like this would be a lame excuse to not give the kalos starters mega evos, if thats the direction their heading. "Ash-Greninja is the form that Greninja takes when the bond between it and Ash is raised to the limit."
I assumed that they were saving gen 6 mega evos for the XY sequel game, and it would be silly to not give megas to the starters, or even worse, none for gen 6 at all for that matter.
What if Greninja is in that awkward pre-mega stage, but cant actually fully mega evolve until they get the keystones? Would that also mean Florges gets a mega evo too?
