I wonder if Xerneas has any connection to the musketeer quartet. I mean it looks kinda like Cobalion and Virizion, its legs almost look like swords and the musketeers are based on french characters and this new region has some France elements in it.
Yveltal looks damn cool. Looks like something out of shadow of the colossus. Sure hope it and Xerneas has what it takes to fight in Ubers with Reshiram, Mewtwo and the others
If the mascots and the potential Z mascot are drawn from norse mythology I wonder if there will be pokemon (legendary or pseudo legendary) that reference Thor, Loki or Odin.
