The Aura Trio (also known as the Yggdrasil Trio and Axis Trio by some) is a trio of Legendary Pokémon that originate in the Kalos region and comprises Zygarde, Xerneas and Yveltal. The three members are based on Yggdrasil, which is a huge tree in Norse cosmology. It is said to be protected by three guardians. A bird protects the upper part of the tree. A deer protects the soil of the tree. A snake protects the underground of the tree. The same is true for Xerneas, Yveltal and Zygarde.
