Earthia is the mother of Galaxina and Cosmo the Seedrian, presumably the leader of Cosmo's clan. She chose to flee after the Green Planet was destroyed. Surviving on a fake Planet Egg, she transformed into her true self; a giant tree. The seeds that come from this tree make new offspring, depending if cared for or not. After that, she gives birth to the last of her offspring, which was Cosmo. Growing weaker, Earthia died when the Metarex landed on her ship. She later appears in a holographic image on the abandoned Green Planet, displaying how the planet fell. At the final moment of the forestation project, Earthia appears to Cosmo and tells her what to do, and suddenly, Cosmo's amulet shatters. Her last appearance is when Dark Oak has been defeated; suddenly a light (which is Earthia) appears to him and says that they have a second chance. They both then disappear in a flash of light and are never seen again.
Earthia can produce healing seeds and can control other plants. She can also create force fields by using the orb attached to her chest, which are invulnerable to harm. Lastly, she has the ability to levitate.
She is voiced by Veronica Taylor in English Dub.
