I really like this Pokemon, as well as the typing of it, it also ties up the XYZ and Norse Mythology theories that put on Xerneas and Yveltal.
It is called the Order Pokemon which makes sense
Hope you like, tell me in the comments below, Enjoy!
Also, Just to mention, these are not 100% confirmed. It could be fake
Anyway, by faster do you mean as far as their individual speed stats? Because I'm sure those can be the same if they're at different levels and/or with items like carbos.
Yveltel and Xerneas are the only Pokemon affected by Zygarde's ability.
Also, when Aron says faster, you would be correct. Both, oddly enough, have the same base Speed stat (90), so it seems it will come down to a random selection of who gets their weather and who doesn't (as both peak at 306 Speed if with max EVs and a Speed positive nature).
When I read this thing's pokedex entry, It said it watched people unbalanced the enviorment.
So I named it (Jolly) Green Giant!
too bad it wasn't Jolly Natured...
