Metal Sonic is a major antagonist that appears in the Sonic the Hedgehog comic series published by IDW Publishing. He is a villanous Badnik created by Dr. Eggman to rival the skills of Sonic the Hedgehog.

When Dr. Eggman disappeared after the Eggman Empire lost its war with the Resistance, Metal Sonic took over as ruler of the Eggman Empire to conquer the world on behalf of his master.


Metal Sonic was created in the image of Sonic the Hedgehog, and is thus mostly built of blue metal. He has a yellow circular depression in his chest with a black center, mirroring the peach skin on Sonic's chest. His head has metal fins resembling Sonic's quills, and a pair of triangular "ears." Metal Sonic has a muzzle, shoulder plates, and upper arms, legs, and fingers made out of silvery metal. His palms are black, while the backs of his hands are square yellow plates. His forearms and lower legs are blue metal like his head and torso, and he has red feet with white stripes designed to resemble Sonic's shoes. He has optic sensors with black sclera and red irises.



Sonic beats Metal Sonic

Metal Sonic defeated by Sonic, from Sonic the Hedgehog #7.

In the recent past, Metal Sonic transformed into Neo Metal Sonic in an attempt to take over the Eggman Empire after he gained an independent personality.[1] After disguising himself as Dr. Eggman, he eventually clashed with Team Sonic in the Egg Emperor mech.[2] Not only did he lose in this battle, but after he was found out to be a fake, he was defeated by Team Sonic and turned back to normal. After this defeat, Eggman repaired Metal Sonic and removed the rebelliousness from his coding.[1] Sonic and Metal Sonic clashed at least once since then.[1]

The War

Eggman eventually decided to upgrade Metal Sonic to Neo Metal Sonic once again so he could be used as his greatest weapon in the final battle during the war between the Eggman Empire and the Resistance. During his upgrade, Eggman had phantoms of Metal Sonic fight in his place.[1] As an addition to his upgrade, Metal Sonic received Eggman's bio-data, giving him his creator's drive, vision and genius, and had the requirements needed to assume his final form lessened.[1][3] By the time Metal Sonic's upgrade was complete however, the war was won by the Resistance and Dr. Eggman had vanished.[1]

Determined to make sure the Dr. Eggman's reign remained unbroken, Neo Metal Sonic decided to use Eggman's persona and lead the Eggman Empire, with the intention of conquering the world as Eggman and then find the real doctor so he could hand the control of the world over to him.[1]


Approximately a month after the Eggman Empire lost the war, Neo Metal Sonic, under the guise of Dr. Eggman, began directing the wild Badnik hordes into attacking villages across the globe in order to lure Sonic and his allies out and make subtle attempts to eliminate them.[2][4][5][6] Along the way, Neo Metal Sonic discovered that the Master Emerald had been left unguarded, which meant he could accelerate his master plan considerably.[5]

The Fate of Dr. Eggman

Eventually, Neo Metal Sonic lost track of Sonic and his allies.[7] Despite this, he began making his next move by having the Egg Fleet move into position for an invasion of Angel Island.[8][1] On his way to join his fleet however, Neo Metal Sonic came across Sonic when the hedgehog invaded his flagship and saw through his Eggman disguise. Neo Metal Sonic subsequently dropped his disguise and indulged Sonic in his current motives before engaging him in battle in hopes of making him tell him where Eggman was. In the end, Sonic managed to escape Neo Metal Sonic, although that did little to deter the robot, who proceeded with his invasion of Angel Island.[1] After taking over the island and securing the Master Emerald for himself, Neo Metal Sonic patiently awaited Sonic's arrival.[9]

The Battle for Angel Island

Eventually, Sonic and company discovered that Neo Metal Sonic had turned Angel Island into a flying fortress, and began a liberation attempt. Soon after, Sonic and Knuckles themselves confronted Neo Metal Sonic at the Master Emerald's shrine. In response, Neo Metal Sonic used the Master Emerald to turn into Super Neo Metal Sonic.[10] Super Neo Metal Sonic proceeded to toy with Sonic and Knuckles until Shadow arrived and launched a surprise attack on Super Neo Metal Sonic that reverted him back to Neo Metal Sonic. As he got beaten back by Shadow however, Neo Metal Sonic copied Shadow's biodata. With Sonic and Shadow's biodata and the Master Emerald itself now in hand, Neo Metal Sonic had all he needed to assume his final form. Absorbing his surrounding stronghold, Neo Metal Sonic transformed into Master Overlord.[3]


Metal Sonic is a ruthless and cold-hearted killing machine. Incredibly intelligent and self-aware for an Eggman robot, Metal Sonic at one point evolved to become an independent, rebellious and power-hungry tyrant willing to betray his own creator. After his defeat however, he was stripped of his rebellious coding, turning him into a more obedient robot.[1]


Metal Sonic continues Eggman's reign for his sake, from Sonic the Hedgehog #7.

Nowadays, Metal Sonic is completely devoted to Dr. Eggman and his role of serving the Eggman Empire. His loyalty towards his creator and purpose has proven to be so great that he chose to step up to lead the Eggman Empire and conquer the world in the doctor's stead and likeness after he went missing to insure that Eggman's reign remained unbroken. Should the world become his, he would then faithfully hand the empire over to Dr. Eggman. He has also proven to be very grounded in his beliefs: even when in a position of absolute power within the Eggman Empire, Metal Sonic insists that he is only a servant to the Eggman Empire, and that the only one fit to rule it is Eggman himself.[1]

Metal Sonic also has an unhealthy obsession with his organic template, Sonic the Hedgehog. Referring to the real Sonic as his "double" and "loathsome copy", Metal Sonic believes himself to be the real Sonic in a sense; after he believed Sonic to be dead, Metal Sonic proclaimed that he was the "one, true Sonic".[1]

In comparison to Dr. Eggman, Metal Sonic is much more subtle in his tactics. Rather than stepping up to claim responsibility whenever he commits something malicious, Metal Sonic tends to operate in the shadows or in a disguise.[4][8] He is similarly not one to prattle loudly about his master plans before they are carried out.[1] Metal Sonic also demonstrated a very calm and enduringly patient demeanor during his time ruling the Eggman Empire.[4][1] This is mainly due to his own arrogance and belief in his supposedly impending victories.[1] He rarely lets his setbacks get to him and he gets no more than mildly annoyed whenever one of his plans does not go as intended.[2][4][1] That does not mean he does not possess a temper however, as he has been known to have episodes of angry outburst whenever something unexpected happens.[7][1]
