Dark Gaia energy

Dark Gaia Energy is a type of supernatural energy in the Sonic the Hedgehog comic book series and its spin-offs.

Overview
Dark Gaia Energy is an energy form innate to Dark Gaia and his “offsprings ”, and is the essence of their being. It is an energy that gradually builds up within the core of Sonic’s World. It is similar to Chaos Energy in that it can be used for supernatural abilities and techniques.

Dark Gaia Energy, when exposed to individuals, can have negative effects, as demonstrated by the aggressive tendencies Sonic displayed upon taking in some of this energy form. It can also be used to greatly empower individuals, even giving them abilities they previously didn’t have. While usage of Dark Gaia Energy usually results in the eyes of the users turning purple, enough Dark Gaia Energy can lead to a full on transformation, as shown with Sonic the Werehog.

Dark Gaia Energy has also been noted to be, according to Walter Naugus, very similar to the energies of Ixis, so much so that the troll mistook it for being the power of Ixis until Wendy corrected him.
