Original Continuity


The Master Emerald

The Master Emerald is a massive Chaos Emerald that serves to keep Angel Island in the skies. It was created by the combined might of Athair and the Brotherhood of Guardians, during a confrontation between Super Sonic, Hyper Knuckles, Turbo Tails and the recently empowered Mammoth Mogul. The Master Emerald contains the powers of the twelve individual Chaos Emeralds which originally held Angel Island afloat, along with two more- one from Mammoth Mogul and another emerald recovered from a pocket Zone. Since its creation it has been used-or sought after- by heroes and villains alike.




Mammoth Mogul trapped in the newly created Master Emerald

When Mammoth Mogul stole the power of 11 Chaos Emeralds from the super being Enerjak, he transported Sonic the Hedgehog, Tails and Knuckles the Echidna to an alternate Zone. They managed to escape the zone however, and with the powers of the Power Rings, Sonic and Knuckles transformed into Super Sonic and Hyper Knuckles, while Tails managed to transform into Turbo Tails with the help of Athair and the Ancient Walkers. With their combined powers along with help from Athair and the Brotherhood of Guardians, Master Mogul's powers were utilized and transformed the power of the numerous Chaos Emeralds-Mogul's twelve plus the two that had held the island aloft at that point-into a single Master Emerald, with Mogul trapped within. This new massive Chaos Emerald was then used to maintain Angel Island's low orbit of the planet Mobius. (StH: #56, KtE: #9)

Sought Out By Villains

After Dr. Eggman liberated Chaos from the Black Emerald, he proceeded to attack the Floating Island with a legion of Shadowbots and the Egg Carrier while the Brotherhood of Guardians' defenses were still down due to tampering from Hunter. The Master Emerald was shattered, and pieces of it were used to help sustain Chaos in his weakened state. Eventually however, Knuckles was able to locate and retrieve all of the pieces of the shattered Master Emerald, with the Brotherhood providing a new altar for it to better harness its magical powers. Mammoth Mogul escaped as a result of the Emerald's fragmentation, and though he was in a weakened state, pulled together as much power as he could to strike a lethal blow to the Ancient Walkers. (StH: #79, #80, #81, #84, #162)

During the surprise invasion by the Eggman Empire after the Xorda attack was fended off, the Brotherhood of Guardians (sans Locke) fought off an entire army of Egg Pawns in defence of the Master Emerald, while the rest of the island was simultaneously attacked by the combined forces of the Eggman Empire and the Dingo Regime under the new leadership of Kage Von Stryker, who had allied with Dr. Eggman. The Brotherhood managed to successfully defend the Master Emerald, but were subsequently captured in their weakened state by Dr. Finitevus. Locke managed to successfully protect the Master Emerald on his own, until after Sonic's return, when he was forced to turn its protection over to the Dark Legion when its location was discovered. Locke was captured while the Dark Legion safely moved it. Eventually, the Master Emerald played a pivotal role when it restored Knuckles' lost Chaos-based powers and transformed him into Super Knuckles and allowed him to kill Hunter. The Master Emerald was then re-located once again, with Locke protecting it from harm. (StH: #139, #140, #141)

Some time later, Evil Sonic, with help from Rouge, attempted to steal the Master Emerald. While Rouge distracted Locke, Evil Sonic managed to get into the chamber, but was soon stopped when he faced off against Sonic Prime, who had returned from Anti Mobius. Locke sent Anti Sonic flying away when he realized which was the real Sonic, and went back to protecting it. (StH: #150, #151)

Rouge and Evil Sonic later returned, and while the two fought against Locke directly, they were able to get closer to the Master Emerald. Evil Sonic managed to get onto the Master Emerald while Rouge fought with Locke, and began to transform. His transformation was stopped mid-way, altering his appearance into green, whereupon he took on the name Scourge. Scourge then defeated Locke, and used the Master Emerald to use Chaos Control to teleport himself and Rouge away. (StH: #160, #161)

The Great Harmony

When A.D.A.M. enacted his plan to draw all of the Chaos Emeralds from around the universe to Mobius, his plans ultimately allowed Tails, the "Chosen One", to fulfil the prophecy of producing the Great Harmony. While A.D.A.M. was distracted, Shadow assisted Tails and opening a portal to the Zone of Silence. There, Tails sent all of the Chaos Emeralds where they would be safe and out of reach from villains, thus fulfilling the prophecy set out by the Ancient Walkers. When A.D.A.M. was using a captured Shadow and Tails to pull all of the Chaos Emeralds to Mobius, he was perplexed as to why the Master Emerald was not amongst them. The combined effort of Locke and Dr. Finitevus ensured the Master Emerald remained secured on Angel Island. (StH: #169)

Return of Enerjak

Not longer after the Great Harmony, Dr. Finitevus managed to con Locke into entrusting him with the care of the Master Emerald while he searched for the Brotherhood of Guardians. During Locke's absence, Finitevus enacted the final phases of his ultimate plan to destroy Mobius by reviving Enerjak and placed a Hex on the Master Emerald. Also during this time, Rouge put out a claim that she had stolen the Emerald and would sell it to the highest bidder, but this was a ruse intended to draw in various criminals for capture. When Knuckles the Echidna returned to Angel Island to assist his father Locke in protecting the Echidnas, he was ambushed by the Destructix and brought before Finitevus. The mad scientist informed him of the destruction of Albion and how many echidnas were alive. With this as persuasion, Finitevus convinced Knuckles to pull energy from the Master Emerald and become Enerjak. The moment he did this, Knuckles became a slave to Finitevus' hex, making his ideals bend to those of the albino Echidna. (StH: #171, #173, #181)

When Sonic and Julie-Su arrived on the scene, Finitevus informed them that no one could use the power of the Master Emerald except for Knuckles due to the hex he placed on it. Despite this, Sonic some how managed to use its power to turn into Super Sonic. Which this power, Sonic managed to distract Knuckles (who was presently Enerjak) long enough for Locke to surrender his life and thereby break the hex Finitevus placed on the Master Emerald. With the hex broken, Knuckles returned to normal and forced Finitevus to flee. Since then, Knuckles has vowed to protect the Master Emerald, even if he must do it alone. (StH: #183, #184)

Shrine Isle

Knuckles Guarding the Master Emerald

Knuckles guarding the Master Emerald.

Having been separated from the mainland of Angel Island by the battle between Super Sonic and Enerjak, the Master Emerald Shrine now floats a short distance away. The Chaotix bridged this gap during a trip to the island to check up on Knuckles, during which Rouge the Bat convinced the Guardian that he could watch over the Master Emerald and continue to take part in the war against Dr. Eggman without choosing one or the other by using a Warp Ring taken from Dr. Finitevus. (StH: #186)

Later on, the Master Emerald was fought over by Espio and Knuckles, the former having been dispatched to steal it by the leaders of the Iron Dominion. The fight ended when Espio told Knuckles he had conflicting orders and couldn't complete his mission, as doing so would force him to kill Knuckles. (StH: #203, #204)

Vector the Crocodile and Ray the Flying Squirrel later took guard duty over the Emerald while Knuckles went on another mission. Ray managed to grill Vector and learned a little bit about his past. Right after that, they were attacked by what looked to be new models of the Wing Dingoes. They then attempted to fight off the robot horde and keep them away from the Emerald. Ray managed to trick the Dingoes into fleeing by using the Master Emerald to fake a super transformation, much to Vector's surprise. Trying to mask his lack of understanding, Vector asked Ray how he had used the emerald in such a way; Ray replied that, as Knuckles had explained to him, the chaos energy within the Master Emerald can react to anyone, just more so with some people than others. Angel Island's capture forced the pair to leave the Emerald undefended, though Ray later returned with Julie-Su at Knuckles behest. The two then helped Knuckles prevent Finitevus from seizing the Emerald, likewise keeping it out of the hands of the Dark Egg Legion of Downunda, who had attempted to capture it for their own uses. (SU: #9, #10, #11, #12)

No further attempts were made to seize the Master Emerald or utilize its power until Thrash the Devil learned that its energies could super-charge a Warp Ring. Accompanied by his pack of Devil Dogs, he attacked Shrine Isle, overwhelming Julie-Su and Saffron Bee, who had been left to protect the Emerald while Knuckles traveled to Albion. Thrash then used the Emerald's power to infuse his Warp Ring, and used it to banish the two defenders and most of the remaining Echidnas from Mobius. (StH: #244)


The Master Emerald is a fusion of the power of fourteen Chaos Emeralds-though one was later removed when Mammoth Mogul escaped, possibly reducing its power somewhat-giving its full scope of power the same as that of a Chaos Emerald but with the notable ability to control and subdue their energies. The Master Emerald alone can induce super transformation and greatly enhance the physical capabilities of those able to channel its ley lines. It is extremely potent in terms of raw power and energy.

Background Information

  • Due to misconceptions made in the early days of the comic, history and events surrounding the Master Emerald differed greatly from those in the games series; as such, many changes had to be made (in particular, concerning the associations of Tikal and Chaos) in order to adapt them to the comic's story.
