Gaia is the spirit of the Earth. She is a modern rendition of the Ancient Greek goddess of the Earth. Tired with the destruction and pollution of Earth, she summons the Planeteers to defend Earth and gives them their elemental rings.

Gaia apparently lives on an island with large crystals in the middle of the ocean, although it is not known if it is on Earth or another dimension. She appears to be omnipresent; she can appear in any time or place she wishes, and can communicate telepathically with anyone at any point in time. She is bound to Earth, and her health and well being seem to be connected with the condition of the planet.

It should be noted that this representation of Gaia was depicted not as a Hellenic Greek, but as a mix of the three primary racial ethnicities: dark brown skin, prominent cheekbones, wavy black hair, and blue eyes.
