So I've completed the Sun and Moon Demo, I haven't transferred Greninja yet to the main game, but before I do so I want to make sure. I've heard that Greninja won't obey you unless you've completed two GRAND Trails, is that true?
I'm already on the 2nd Island and I've just completed Kiawe's Trial and I'm on my way to do Mallow's Trial. So do I have to complete the Grand Trial after Mallow's Trial to get Greninja to obey me?
Smogon Frog is now my favorite starter Pokemon
