Dark Gaia (Archie)

Dark Gaia is a character that appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. It is a malevolent deity residing beneath the surface of Sonic's World which instigates corruption and the supposed destruction of the world. It supposedly has a connection to the event where the planet shatters every ten thousandth year, the most recent being the Shattered World Crisis.

Powers and Abilities
Dark Gaia is capable of exerting its essence as a form of dark energy. This energy is highly dangerous, corruptive and has incredible mutagenic properties, capable of causing a total cellular re-write, and can as well create monsters composed entirely of it, block spirits like Tikal and turn hearts cruel.

Trivia

 * Dark Gaia was first mentioned in the Archie Comics in Sonic the Hedgehog #197, though it did not make an appearance and was only referred to as "it"; this is likely because the story in which it was featured was merely a promo for Sonic Unleashed. It was first in Sonic the Hedgehog #259 that Dark Gaia made an appearance in the Archie Comics as an illustration in the Gaia Manuscripts.
