I think this is interesting. Though if Ash and Greninja biomerge...we'll have another coincidence of Pokémon introducing new things that are very Digimon.
Or it's just Mega Greninja. Because we have mega evolution. You're twisting it to totally unrealistic views.
Wait, the little larvae green blob thing is just a part of Zygarde then?...and it becomes the brain of the new forms....so the Zygarde that we know doesn't uhm....think?
Most likely just a mega evolution.
Excuse me, I can hypothesize. And as Serebii says the magazine mentions it looks sort of like Ash's clothes <.<Or it's just Mega Greninja. Because we have mega evolution. You're twisting it to totally unrealistic views.
I doubt that it'll ever be a Mega Evolution since the difference is just a bit too small. But on the poster, we know Ash currently has a Frogadier and it doesn't appear. So it might probably evolve into that Greninja.

It doesn't say that anywhere.So, apparently Greninja has a stronger bond with Ash than Pikachu.
