Vayamon- Gaia

Gaia is Earth's mentor. Even though Gaia can talk, Gaia is a spirit and cannot preform battles. (Very much like Master Eon from the skylanders series)

Gaia is the goddess of Vayroia, the Vayamon world. She created the Gaia Orb, a powerful artifact that is responsible for Vayamon powers. 

Gaia is much bigger than Earth. Gaia is the ancestor to all Eartaias, Earth's species. In fact, Eartaias are the one Vayamon species created in Gaia’s image. 

Only Eartaias like Earth can summon Gaia.
