Yveltal

Yveltal, also known as the god of destruction in Pokémon's universe, is a playfully oblivious embodiment/representation of death. Whether it comes to spending time with either Xerneas and/or Zygarde, or attempting to interact with any form of life he crosses, he is bound to cause an drastic impact in an attempt to cause amusement. In this AU of Pokémon, whether there are humans or not is up to you, HOWEVER: If you are planning to go with no humans in this world, I would advise you to take on a more Eeveelution Squad sort of AU where there are still societies, just run by Pokémon. Anyways, that's all, enjoy!
