The Chaos Emeralds are objects that appear in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. They are mysterious magical gemstone of nearly infinite power that come in seven distinct colored varieties: peridot (green), aquamarine (cyan), sapphire (blue), ruby (red), amethyst (purple), topaz (yellow) and diamond (grey). Due to their properties, the Chaos Emeralds have often been the center of conflict across space and time in several different realities.
Powers and traits
Each emerald contains supposedly unlimited quantities of pure Chaos energy, a highly powerful form of energy able to warp space and time when properly utilized. Alone, an Emerald is able to act as an extremely effective energy resource for machines, empower an individual with magical powers, enhance innate talents, and cause supernatural phenomenon. When all seven Emeralds are gathered they have unlimited energy potential and can imbue whoever wields them with a powerful, nigh-invulnerable state.
The Chaos Emeralds have been at the center of many of Dr. Eggman's schemes. The Emeralds have been gathered multiple times and their powers harnessed, having known to have been used to power up the water god Chaos, to power the Eclipse Cannon and numerous other super-weapons usually of Eggman's making. In the majority of these instances, Sonic the Hedgehog and others have foiled these plans by harnessing the Emeralds power themselves. The Emeralds have sometimes been the sought after by other major threats, such as the Black Arms.
The blue Chaos Emerald was discovered by Dr. Albert W. Wily. Upon trying to analyze it, the Emerald brought him into contact with Dr. Eggman. As the two joined forces, Wily created the Skull Egg Zone with the blue Chaos Emerald for them to meet in. There, Eggman and Wily devised their ultimate agenda: to collect all seven Chaos Emeralds to power up a "Super Genesis Wave" that would have the potential to let them rewrite both universes without any limitations, allowing the doctors to become-in their own minds-gods.
Using the blue Chaos Emerald, Drs. Eggman and Wily reshaped their words with another Genesis Wave which scattered the other Emeralds across both worlds. Through the efforts of their Roboticized Masters, Eggman and Wily obtained the remaining gemstones, despite interference from Sonic, Mega Man and their allies.
The seven Emeralds were subsequently plugged into the Genesis Reactor to power up the Super Genesis Wave, eventually finishing as the doctors had caught Sonic and Mega Man. As the doctors gloated over their impending victory, however, Knuckles and Proto Man arrived to threaten their plans, forcing them to draw energy from the Emeralds to super charge their Egg-Wily Machine X. Then, as the Super Genesis Wave was unleashed, Sonic and Mega Man harnessed the Chaos Emeralds to transform into Super Sonic and Super Armor Mega Man and defeat the doctors' machine. Unaffected by the wave, the two heroes tried to employ Chaos Control in an effort to restore their worlds. Mega Man succeeded without interference, but Sonic's efforts were disrupted due to an attack by Dr. Eggman.
Shattered World Crisis and Worlds Unite
- Note: From the readers point of view, this picks up from where the Chaos Emeralds' original timeline ended.
When the Shattered World Crisis occurred, both Eggman and the Freedom Fighters learned from the Gaia Manuscripts that the seven Chaos Emeralds could reassemble their shattered planet if they were brought to the Gaia Temples. As such, both the Freedom Fighters and the Egg Army began scouring the planet for them, with both Sally Acorn and Eggman hiring the Chaotix and Hooligans, respectively, to aid them. The Freedom Fighters soon located the purple Emerald in Crystal Cave under guard by the Badnik Horde, but were able to retrieve it while ensuring that the cavern would not be damaged. The red Emerald was found by Chip, who was briefly kidnapped by the Hooligans along with the Emerald, but both were rescued by Knuckles the Echidna and the Chaotix and brought to Angel Island for safekeeping. The Hooligans were subsequently ordered to take part in the Chaos Emerald Championship in Casino Park in order to obtain the green Emerald which Breezie the Hedgehog's crew had found while overseeing some repairs. Meanwhile, Egg Boss Thunderbolt obtained the white Emerald and was instructed by Eggman to use it as bait for the Freedom Fighters.
The Freedom Fighters soon took the bait and fell into Thunderbolt's trap, but were able to recover the grey Emerald regardless thanks to Sonic's unexpected transformation into the Sonic the Werehog. Unfortunately, a second trap involving the blue Chaos Emerald saw the Emerald being secured by Eggman's forces, with the Freedom Fighters barely escaping when they tried to steal it. They soon learned that the green Emerald had been put up as a prize for the Chaos Emerald Championship. Meanwhile, Dr. Eggman, having learned of the sheer power of Dark Gaia released by the planet's shattering, determined to secure the Chaos Emeralds and Gaia Temples to prevent the planet's restoration so he could collect Dark Gaia's power. The yellow Emerald was then discovered on Isolated Island, its power making the local Lake of Rings produce Red Star Rings, and became contested between a small squad of the Freedom Fighters and a force of Badniks under Phage, though the heroes managed to secure it. The final Chaos Emerald, the cyan one, was found by G.U.N. forces at Crystal Desert Zone, only for Metal Sonic to snag it from the dig site. Luckily, the Freedom Fighters arrived and Sonic managed to take the Emerald back with some help from Silver the Hedgehog after chasing the robot into the Burning Ruin Zone.
The Freedom Fighters and Eggman later pooled all seven Emeralds during the conflict with Sigma, where they were used by Super Sonic and Super Armor Mega Man to defeat the maverick overlord. However, Xander Payne later reversed these events using one of the Genesis Portals, leaving the Chaos Emeralds divided between Eggman and his foes once again.
As a result of these alterations to time, the blue Emerald previously secured by Eggman went off course on its way to the Death Egg. It later ended up under the protection of Cassia the Pronghorn and her sister Clove the Pronghorn, which led to an engagement between them and several of the Freedom Fighters, with the Freedom Fighters getting away with the Emerald.
Having collected all the Emeralds at this point, the Freedom Fighters believed that they could finally fix the world. They hid the Emeralds and the Gaia Keys in Castle Acorn's vault, under the protection of Nigel Acorn and Gemerl. However, Eggman had found out the Freedom Fighters' plan to fix the world and the locale of the Chaos Emeralds and Gaia Keys. Due to this Eggman sent the Hooligans, the Witchcarters and Metal Sonic to attack Castle Acorn and steal the Emeralds for himself. After forcing Gregorios to reveal the location of the Gaia Gate, Eggman had his Egg SWATs place them in each Gaia Temple to form the Gaia Colossus. He brought the Gaia Colossus to Eggman Land, trapping Chip inside it. Eggman was soon defeated by Sonic once again and the hedgehog used the Chaos Emeralds to become Super Sonic and defeat Perfect Dark Gaia.
- Emerald is the name of a specific gem of the beryl variety, a family known for its wide array of possibly colors. "Emerald" is also used in Japan as a generic term for jewels.
- "Chaos" in the English language means disorder and an irregular, unpredictable action that was remarkably sensitive to regular changes in environment, similar to how the Chaos Emeralds in the series act. "Chaos" as used in Greek refers to a large emptiness, or space. "Space" in English came to be a general term meaning both everything outside of the Earth’s atmosphere and the placement of objects in relation to one another.
- The colors of the Chaos Emeralds were chosen based on the three primary colors of light (red, blue, and green), the three secondary colors which are mixtures of the primary colors (red + blue = purple, blue + green = cyan, and green + red = yellow), and finally grey which is a mixture of all three primary colors (red + blue + green = grey).
