are seven emeralds of great power, from the Sonic the Hedgehog video games. The Chaos Emeralds have mystical properties and abilities, and the holder of them all can use them for a large variety of things, such as creating a powerful super transformation, powering machines, and warping time and space. Due to the immense powers they possesses, they are usually the target of villains, who wants to use them to fuel their own evil ambitions, and of heroes, who wants to keep them away from the villains and use them for good.
