Chaos Emerald (Archie)

The Chaos Emeralds are a series of seven gems in different color in the Sonic the Hedgehog comics, made by Archie Comics. The Chaos Emeralds first appeared on Sonic the Hedgehog #4, where Sonic the Hedgehog had got the seven, green-colored emeralds, as well as fifty rings, to turn into Super Sonic. Sonic, however, is not the only Mobian to turn into a super form via the emeralds; Shadow the Hedgehog and Miles "Tails" Prower also can turn into super forms.

The number of Chaos Emeralds have varied since the beginning of the comics; originally, there was seven, but they were all colored green and they were shaped similar to how the Chaos Emeralds in Sonic the Hedgehog video game. But, eventually, when A.D.A.M. had summoned all of the Chaos Emeralds of the universe to Mobius, it would have been known that only all the Chaos Emeralds on Mobius were green-colored. After A.D.A.M.'s death, Feist had took the Chaos Emeralds into his newly created Special Zone and combine them into seven powerful emeralds. So far, there are seven Chaos Emeralds (red, blue, yellow, green, purple, cyan, and white) and a gray-colored Chaos Emerald, which is unique compared the other seven gems.

Known Chaos Emeralds
In the year 3237, Dr. Eggman's "son", A.D.A.M., had brought all of the Chaos Emeralds of the universe (excluding the Master Emerald) to fight Super Sonic to a standstill. But, when A.D.A.M.'s host, Tommy Turtle, had caught on to his normal self and sacrifice himself to destroy A.D.A.M. via running into one of the ships on the Egg Fleet. Since then, the Chaos Emeralds were brought to the Special Zone where Feist combine them together into seven Chaos Emeralds. (StH #169)

Green Chaos Emerald
The Green Chaos Emeralds were originally unique to the planet Mobius prior to A.D.A.M. gathering them up. These type of emeralds first appeared in Sonic the Hedgehog #4, as Sonic used them to turn into Super Sonic and to defeat Universalamander. Later, after A.D.A.M. brought the Chaos Emeralds of the universe to Mobius, Feist combined the Chaos Emeralds into seven colored gems. The green Chaos Emerald was first obtained by Marine the Raccoon after Sonic and Tails crash-landed on Seagull Island. Marine had found it, but it was quickly taken by Johnny. Sometime later, Shadow and Metal Sonic v3.3 transported themselves into the Sol Dimension only to find Blaze the Cat and Marine the Raccoon. Once defeating Metal Sonic, Blaze gave the green Chaos Emerald back to Shadow, as it has found enough Sol Emeralds to gather the rest. Shadow used this emerald to transport himself back home to G.U.N. Headquarters, where the green Chaos Emerald would be used to develop better and stronger robots. (StH #4, #169, #180, SU #1)

Red Chaos Emerald
The Red Chaos Emeralds were originally located on the alien planet Thoraxia. After A.D.A.M.'s death, Feist took up the emeralds of the universe and combine them into seven gems. Later on, Team Dark–Shadow the Hedgehog, Rouge the Bat, and Omega–went to the Special Zone to acquire the red Chaos Emerald. They went twice into the zone to get the emerald; Shadow and Rouge went the first time to get it, but failed. The second time, however, was when Omega shot at Feist for the emerald after being unfair at his challenges in order for Shadow to take the emerald from the god and use Chaos Control inside the zone. Since then, it has belonged to G.U.N., along with the green Chaos Emerald. (StH #169, SU #4)

Purple Chaos Emerald
The Purple Chaos Emeralds were originally on the ruins of the planet Teragosa 6 before being taken from A.D.A.M. to be relocated in Mobius. After A.D.A.M.'s death, the Chaos Emeralds were taken to the Special Zone where Feist would combine them into seven gems. Later on, Sonic and Geoffrey St. John would go to the Special Zone to acquire the purple Chaos Emerald. Unfortunately for Sonic, Geoffrey shot Sonic in the back and the skunk went to Mammoth Mogul to get back the deeply-insane Ixis Naugus. The Chaos Emerald gave Naugus self-control once again and since then, the purple Chaos Emerald has been on Naugus' staff. (StH #169, #219, #220)

Blue Chaos Emerald
The Blue Chaos Emeralds were originally from the alien species Xorda's homeplanet prior A.D.A.M. taking the Chaos Emeralds of the universe away. After A.D.A.M.'s death, Feist took the Chaos Emeralds of the universe and combine them into seven gems. Later on, after the Iron Dominion left New Mobotropolis, Dr. Eggman escaped his insanity and, along with Snively Robotnik, went to the Special Zone to acquire a Chaos Emerald. He was successful and he used the gem to launch the newly-built Death Egg. He also used the emerald to activate Operation: Clean Sweep, whereas he can cause a time shift in reality. After Super Sonic was able to fix Mobius to the way it was, Eggman had lost the blue Chaos Emerald in the post-GENESIS world. However, Eggman had decided to search for the emerald, which was the exact same time as when, in another world, Dr. Wily obtained the emerald in his dimension. This lead into another GENESIS effect, only instead of one world being effected, another was effected. (StH #169, #223, #224, #225, #231, #247)
