Then legendary Then pokemon And then say if gen 6 will overtake it.
Unova is my favourite, just because it looks so cool. Probably zekrom, because it has two of my favourite typing. If I have to choose, I would say garchomp, because its up there but not my certain favourite. Yeah, the way kalos is now I'm sure it will be a better region than unova, provide me with a favourite pokemon but I doubt it will make something better than zekrom.

Kanto Xerneas - I don't know its backstory yet, but it has an amazing design. I love it! Umbreon
Kalos will probably not beat Kanto in my mind. That is because I have a nostalgic fondness for Kanto.
Xerneas = Gen VI.
Sylveon < Umbreon in terms of design IMO, but it's a pretty decent Eeveelution nonetheless. It might join my Eeveelution team (Umbreon, Flareon, Jolteon, Vaporeon, and Espeon) if the Fairy-type is super effective against more than just Dragon-types.
