The Chaos Emerald (カオス エメラルド Kaosu Emerarudo?) is an object that appears in the Sonic the Hedgehog serialized manga. It refers to legendary gemstones of great power. Only a singular green one has appeared so far, but references has been made to six others existing.
Chaos Emeralds are small emerald cut gems that naturally exude light.
Powers and traits
As shown by Dr. Eggman, Chaos Emeralds can be used as an energy source for machinery. However, their power can also be tapped into directly, as shown by Sonic when he harnessed a Chaos Emerald's energy while it was still being used by Dr. Eggman's robot. As well as briefly changing his appearance, this energy supercharged all of his attacks. Whether this utilization is an ability unique to Sonic is unknown.
