>>52784006It's just a pseudo-mega for the generation where Pokemon would mega evolve. Because Ash didn't have a Pokemon that could Mega Evolve (he did but he didn't bring any back) so Greninja got a new form to compensate.
I'm partially miffed about the exclusivity of it. Battle Bond is supposed to be an ability any Pokemon can have very rarely, and thus there could be other Pokemon that can go pseudo-mega. Yet it's exclusive to just the ninja frog. Wasted potential, if you ask me.
