>>56250946Blaziken already has a Mega, so I think it's be a bit strange to give it a second one, even if it's a different form. And I don't think they'd give the starters new forms if they're also getting Megas.
The way PLA did starters with pulling them from different regions was interesting, but there's no reason that PLZA has to do the same thing. Rather, my prediciton is that it's going to be the base Kalos starters (not with new regional forms because that obviously wouldn't make sense), and all three of them will get Megas. Obviously a Mega Chesnaught would be a good candidate for a shiny new baramon, but I'm also interested in what they'd do for the other two. You could do a lot of interesting things with Delphox, with it being a wizard. Maybe give it a staff, or a broomstick. And I wouldn't be surprised if Mega Greninja was just Ash Greninja under a different name. With how they retconned Battle Bond I think it's very possible.
