Possible Opponents[]


At the beginning of time, the Earth was born, & Dark Gaia with it. Alongside him was his rival, Light Gaia. Both reside within the planet's core, gathering energy for their awakening. Every 1 million years, both deities are resurrected. Dark Gaia, as the deity of destruction, aims to destroy the planet. Light Gaia's duty is to protect the planet, & defeat Dark Gaia. Both exist to create balance for the planet.

During the events of Sonic Unleashed, Eggman awakens Dark Gaia prematurely, resulting in his energy dispersing & spreading out across the planet as it is shattered into pieces. Sonic, who's been turned into a werehog by Dark Gaia's energy, now tries to repair the planet while Dark Gaia's energy solidified into countless monsters spread out across the planet. Towards the end of the game, Eggman creates a beacon that attracts these monsters & gathers them into one place, allowing him to harness the energy. However, this also made it easier for Dark Gaia to gather up his energy & reconstruct his broken body. After Sonic's fight with the Egg Dragoon, Dark Gaia rears its head & takes his energy back from Sonic, stripping him of his werehog form. Before Dark Gaia can kill Sonic, Light Gaia unleashes his power & does battle with Dark Gaia, teaming up with Sonic to defeat him for another 1 million years.

    • Controls numerous energy tentacles for striking foes.
