I can't believe how so many people took Greninja so seriously. When I saw its first picture, I just laughed and moved on, because the design simply looked fake as hell. And the concept was even worse, I mean, that tongue... why the hell would they replace its bubbles with a tongue? That's just stupid.
I've always been pretty positive that it's fake, because if it turns out to be real, it will be the most (bad) fakemon-ish looking Pokémon.
Hawlucha though, I'm getting very close to being 100% sure that it's real, which is very fortunate, since I'm really diggin' both its concept and design.
