Metal Sonic (メタルソニック Metaru Sonikku?) is the evil robotic counterpart of Sonic the Hedgehog, created by Dr. Ivo "Eggman" Robotnik. As well as resembling Sonic, he can also perform many of Sonic's moves, including his homing attack. Metal Sonic is always on the dark side throughout the series, with Sonic Rivals 2 being the only game where he takes a protagonistic role as a playable character. He's noteworthy for being the second most recurring villain in the series, only below Dr. Eggman himself.
Becoming a Popular Villain
Metal Sonic's first appearance was in Sonic CD for the Sega CD console. In this game, he is under the control of Doctor Robotnik and is sent back in time to change the past so that Robotnik can rule the future. Later, he kidnaps Amy Rose, who had been following Sonic. In the Stardust Speedway Zone, he challenges Sonic to a race rather than a traditional boss battle, with Robotnik on their trail and chasing Sonic with a death laser. Periodically, he uses one of two moves - if Sonic is ahead of him, he will explosively accelerate with the V. Max Overdrive Attack, which will make him go four times as fast temporarily and attempt to blast through Sonic. If Sonic is behind him, he'll instead use the Ring Spark Field (Black Shield), which is an electric attack that has a wider range but requires him to decelerate.
If Sonic does not reach the goal in time, the door will close as the scientist kills Sonic with the death laser, while the robotic duplicate looks on and mockingly mimics Sonic's smug finger wave. If Sonic succeeds, the door will close in front of Metal Sonic- unable to stop in time, this causes him to crash and fall off the platform. Robotnik retreats, allowing Sonic to finally rescue Amy and proceed to the last zone. In the Japanese manual, it was claimed that he had all the abilities of the original Sonic and more, but in-game he does not demonstrate this.
Finally a Final Foe
Metal Sonic appears as a surprise boss Sonic or Tails must face in Sonic Triple Trouble. Unlike Sonic CD, it is not a race; it is an actual battle, though Metal Sonic uses his flight and evasion to attack. After being defeated, he wanders off and isn't seen for the rest of the game.
Destroying a Zone
Metal Sonic's next major appearance was in Knuckles' Chaotix, where Dr. Robotnik attempts to absorb the Chaos Rings' powers to wreak havoc in the Newtrogic High Zone. Once again, he has an unorthodox boss battle in which the goal is to stop his machine so it lands on a "damage" mark. After being defeated by the Chaotix, he is seen leaving with Robotnik. This occasion also featured his first supposed power up; a massive, red version of himself called Metal Sonic Kai appears right afterwards. In the bad ending, this monstrosity destroys the island.
Metal Sonic appears as the penultimate boss character in Sonic the Fighters. In this appearance, he demonstrates not only a powerful laser-type move that emits from the hole in his body, but also borrows certain moves from other playable characters (possibly the first signs of his ability to copy his foes). Another version, called Mecha Sonic Model No.29 (AKA "Rocket Metal"), appears in the intro.
Metal Sonic is an unlockable, playable character in Sonic R. To unlock him, the player must find the Sonic Tokens in the Resort Island course, finish the race in at least 3rd place, and then beat him in a one-on-one race against him. Here, the chrome copy plays like an alternate version of Sonic, being faster and slightly harder to steer, but is not quite as fast as Super Sonic. Unlike Sonic, he can't double jump, but thanks to his boosters, can run across water for a short time, which the normal Sonic is incapable of doing.
Metal Sonic Adventure
Metal Sonic makes a cameo in Sonic Adventure (or Sonic Adventure DX), inside a stasis tube in one of Dr. Eggman's hideouts in Mystic Ruins along with a second model of Mecha Sonic from Sonic the Hedgehog 2.
He then appeared as a gift for getting all of the Emblems in subsequent remakes of Sonic Adventure. One could then play as Metal Sonic in Sonic's stages. Metal Sonic essentially acted as an alternate skin for Sonic the Hedgehog; in fact, his playable model is very much made in Sonic's image, and is very different from the Metal Sonic that can be seen in the Mystic Ruins Base.
Metal Sonic's next appearance was as an unlockable multiplayer character in Sonic Adventure 2, and subsequently a standard multiplayer character in the GameCube remake, Sonic Adventure 2: Battle. In the Dreamcast version, he finally demonstrated the ability to act as Sonic, though his moves this time were a carbon copy of Shadow's. Hence, he could perform Chaos Spear and Chaos Control using ring energy. He would learn a stronger version of this technique in Sonic Heroes. In the GameCube version, each 2P character is made more unique, thus he has his own attributes. For one, he can grind faster than Sonic, Shadow, and Amy. He can also project a Black Shield, which is similar to the Ring Spark Field he had in Sonic CD and can jump at a laughably high altitude. The drawback is that he no longer has any other special attacks of his own, though the Black Shield can protect against the special attacks of his opponents, such as Sonic Wind or Chaos Spear, but it can't protect him from Time Stop and Chaos Control. Metal Sonic cannot maneuver while using the Black Shield, but he does maintain his momentum and can exceed max speed when using it before landing on a dash panel.
Tracking Down 12 HeroesMetal Sonic has appeared as the true antagonist in Sonic Heroes. After betraying Dr. Eggman and assuming his disguise, he copies the physical data (and/or abilities) of Sonic, Shadow, Froggy and Chocola to assume his ultimate form, Metal Madness, and later Metal Overlord. This not only increased Metal Sonic's power, but gave him shape-shifting abilities and a new look (a cape, elf-like shoes and longer spines on his head), dubbed Neo Metal Sonic. He manages to achieve this through the use of Chocola, since Chao have a connection to Chaos, the water god of destruction from Sonic Adventure, and Froggy, who periodically had Chaos' tail in Sonic Adventure. In his Metal Overlord form, he transforms into a mechanical dragon-like entity, with one eye over the other, strangely. After he is defeated by Team Super Sonic in his Metal Overlord form, he reverts to his original form. Sonic then challenges Metal Sonic to a future rematch and races away. Metal Sonic then passes out cold, he is last seen being lifted off the ground by Omega, who exchanges a glance with Shadow. What they both have in mind for the metallic hedgehog is never told. At some point, Eggman re-obtains him and reprograms him to be obedient. Strangely, Metal Sonic did not appear in the following game, Shadow the Hedgehog, and was not even mentioned in it, despite the game being a direct continuation.
Metal Sonic appears seemingly reprogrammed by Eggman Nega to serve him and stop Sonic, Knuckles, Shadow and Silver from stopping him in return in Sonic Rivals. Metal Sonic is also playable and can be unlocked by either completing story mode with every character, or by collecting the Metal Madness, Metal Overlord, and Neo Metal Sonic cards. Metal Sonic's signature move is called "Copy Cat" where he uses his opponent's signature move. He also defends Eggman Nega's Flagship.
Agent of Eggman
Metal Sonic returns in Sonic Rivals 2, this time he is playable from the start. Reprogrammed by Dr. Eggman, Metal Sonic appears as a mindless servant, unable to talk (save for various mechanical noises); however, Eggman can talk through Metal via a communicator. Despite not being able to talk, Metal can still hear and follow orders. Metal is sent out by Eggman and teams up with Shadow to stop Eggman Nega from releasing the Ifrit, a destructive monster from an alternate dimension. The cutscenes involving him occasionally glimpse into his thought process, showing he's capable of prioritizing goals. During the game, it is revealed that Eggman placed a Chaos Emerald in Metal Sonic (to hide it from Nega and possibly add extra power to the robot). Eggman Nega also makes his own version of Metal Sonic, Metal Sonic 3.0.
After the teams defeated the Ifrit, everyone escaped through the portal except Shadow, Metal Sonic, Eggman Nega, and presumably Metal Sonic 3.0. However, Shadow and Metal Sonic used the Chaos Emerald inside Metal Sonic to warp out of the Ifrit's dimension with Chaos Control, leaving Eggman Nega trapped inside.
This is the only game where he plays a heroic role. However, this is because he is working for Eggman, who at the time considers Eggman Nega and the Ifrit a bigger threat to him than Sonic, and likely returns to his evil ways when Eggman does.
The Robot Rider
Metal Sonic is a playable character and the mastermind of Story Mode in Sonic Free Riders. He disguised himself as a robot named E-10000B and joined Shadow and Rouge as a Team Dark member tricking them into believing he wanted to help them win the Grand Prix while he actually wanted to copy the other teams' abilities. Eventually, he reveals himself (much to Eggman's surprise, who didn't know Metal Sonic had betrayed him again) and challenges Sonic to a race to prove he is stronger than him. Sonic manages to beat Metal Sonic, who in turn runs away, probably planning up his next scheme since he is now free of Eggman's control.
Destroying Two Sonics
Metal Sonic appears as the first rival boss in Sonic Generations, sporting his classic design.
Classic Sonic finds him in the Hub World as the robot challenges him to a race for the purple Chaos Emerald. The boss fight is very different, as Eggman isn't chasing the two and Metal Sonic destroys the road before the boss fight. They race in Stardust Speedway, just like they did back in Sonic CD. He regains the V. Maximum Overdrive Attack to gain bursts of speed and the chance to attack his non-mechanical namesake, as well as blasting through the streetlamps on either side of the road for them to land on Sonic. After these attempts, he slows down as he has put too much power into his attacks and short-circuits, needing a moment to recharge, giving Sonic the chance to strike him onto the road. After a certain number of hits, Sonic finishes Metal Sonic off by kicking him at the sky (or a tunnel depending on where you are) with the robotic doppelganger creating a fantastic explosion. Unlike the two other rival bosses who come to root Sonic on when he is facing Time Eater, Classic Metal Sonic does not appear.
For the 3DS version of Sonic Generations, Classic Metal Sonic is the boss battle of Casino Night.
Back on Track
Metal Sonic appears in Sonic the Hedgehog 4: Episode II as one of the main villains, the other being Dr. Eggman. He is first fought in White Park Zone, then in an airship in Sky Fortress Zone, and finally twice during the first act of Death Egg mk.II Zone like he did in Stardust Speedway. He is also the only playable character in the additional episode to Sonic the Hedgehog 4, named Sonic the Hedgehog 4: Episode Metal, which tells the story about Metal Sonic's return after the events of Sonic CD.
It is revealed that after the events of Sonic CD, Metal Sonic was left on Little Planet severely damaged for at least one year. Dr. Eggman restored his functionality and sent him to Mad Gear Zone to repair him. Once fully repaired, Metal Sonic intended to get his revenge on Sonic for his humiliating defeat. He then went to Lost Labyrinth Zone, and found a gemstone, which Dr. Eggman was looking for, and its mystic energies made Metal Sonic more powerful than ever. He then headed to Casino Street Zone to find Sonic, but he was not there. He then went to Splash Hill Zone, only to find Sonic had already left. He then found Tails' Rocket and saw Sonic and Tails heading toward Sylvania Castle on the Tornado. He then scared the animals away and chased after them on Tails' Rocket, leading into Episode II.
Metal Sonic then confronts Sonic and Tails in the White Park Zone and is defeated. He later confronts them on an airship near the Sky Fortress Zone, but is defeated. He then flees toward the Death Egg mk.II Zone and confronts Sonic and Tails once again as one of the two final bosses. He loses and then races them, but hits a wall, being electrocuted, and falls over the edge. It is unknown what becomes of him, although it is presumed that Eggman eventually salvaged and restored him for his appearances in Knuckles' Chaotix and Sonic Triple Trouble.

Making Another Cameo
Mario & Sonic Olympic Games Series
Metal Sonic is one of 4 new playable characters in the Mario & Sonic's Olympic series. He is a speed type and rivals with another new character, Bowser Jr.
Mario & Sonic at the Olympic Winter Games
In the DS Adventure Tour, Metal Sonic is one of the major antagonists, joining Bowser and Eggman's side in trying to stop Mario and Sonic from rescuing the Snow Spirits.
Mario & Sonic at the London 2012 Olympic Games
Metal Sonic reappears as a playable speed type character in Mario & Sonic at the London 2012 Olympic Games.
Metal Sonic appears in the 3DS version of Mario & Sonic at the 2012 London Olympic Games but unlike previous installments there are teams (5) for events with only 4 to choose from. Metal Sonic's team is called the Tricksters and the others are Dr. Eggman, Wario and Waluigi. In Story Mode, he appears helping Dr. Eggman and Bowser, who were trying to prevent the Olympics from happening due to the fact that they thought Mario and Sonic were trying to keep them out of the Olympics. In Story Mode, he breaks Waluigi's Waluigiscopes, which were actually a pair of binoculars, so he challenges him so he will pay for them (plus a meddling tax). However, when Waluigi wins, Metal Sonic runs off without paying, so Waluigi chases after him (with Luigi and Charmy following them, who were watching them face off). Eventually Waluigi meets up with Wario (who was chasing Dr. Eggman since his fog would prevent him from setting up a store where he could make money) and ask him to help offering money (while adding that to the Waluigiscopes and the meddling tax) and Wario decides to join him (for his own reasons). Then they meet up with Metal Sonic and Eggman who battled them in an Olympic challenge (with Mario and Luigi watching). After winning they destroy the machine and Mario ask them to keep an eye on them (while he and the others head for the stadium). Eggman escapes later on, but Metal Sonic is not seen.
Return of the Racing Robot
Metal Sonic is the first (and only) official downloadable character in Sonic & SEGA All-Stars Racing. His All Star move is "Maximum Overdrive" which deploys two pads that fly in front of him, emitting lightning bolts between them.
Back On the Track
Metal is confirmed to appear in Sonic & All-Stars Racing Transformed in the bonus edition with Outrun Bay, making him the only character to appear as a DLC in the previous game, and as a regular (but still exclusive) character in this. He drives a alien-like ATV similar to his Metal Overlord transformation, with futuristic versions of a Jet Ski and a Hang glider for water & air respectively.
Other Sonic Robots
- Note - Some early Japanese material refers to Metal Sonic as Mecha Sonic. This has long since been phased out.
Another robot often confused with Metal Sonic is the Sonic robot from Sonic the Hedgehog 2, called Mecha Sonic in Japan ("Mecha" is a Japanese word meaning "Machine" or "mechanical") and Silver Sonic in the western comics. There have been much confusion about whether the name "Mecha Sonic" really is an official name or not, but it was in fact mentioned in both the original Japanese Sonic the Hedgehog 2 manual and the Japanese version of Sonic Jam. This presumed prototype did not have Metal's painted blue color and was also very clunky compared to the sleeker and generally more Sonic-like Metal Sonic. It is destroyed the first time Sonic fights him.
Later on in Sonic & Knuckles, another Sonic robot appeared and attacked both Sonic and Knuckles. It too was called "Mecha Sonic" in the Japanese version of Sonic Jam, but isn't referred to at all in American manuals. Against Sonic and Tails, it appeared three times in Sky Sanctuary Zone - twice in machines Dr. Eggman had used in Sonic the Hedgehog (Green Hill Zone Act 3) and Sonic the Hedgehog 2 (Metropolis Zone Act 3) and once in a one-on-one fight. Against Knuckles it fought one-on-one, as in the final fight with Sonic and Tails, but in the second phase of the battle he used the Master Emerald to go Super (much like Sonic can go Super and become Super Sonic) for brief periods of time. In the end it is destroyed by Knuckles.
Whether these "Mecha" Sonics really are different robots, or if they are in fact one and the same that gets rebuilt whenever he is destroyed (like Metal Sonic) is a source of much debate among fans, as there is no official material that states anything about this.
Mecha Sonic returned to his 16-bit Sonic the Hedgehog 2 incarnation in Sonic the Hedgehog Pocket Adventure as the boss of Aerobase Zone. It is almost identical to its 16-bit counterpart except it has the added ability to dash backwards, like it did in Sonic & Knuckles.
In Sonic Rivals 2, Metal Sonic finds himself a new rival: Metal Sonic Version 3.0, Eggman Nega's personal copy of Metal Sonic. Metal Sonic has an unlockable costume based on him called "Mach 3.0". Metal Sonic Version 3.0 looks just like the real Metal Sonic, but is colored black and yellow, similar to Gemerl.
Due to the backstory of Sonic the Hedgehog 4: Episode II, the events of Sonic Triple Trouble, Knuckles' Chaotix, Sonic the Fighters and Sonic R are further put into question as he has remained dormant since Sonic the Hedgehog CD. It may be possible that is that those games take place after Sonic the Hedgehog 4: Episode II. It is also possible that the games in question have been stricken from canon, or that the Metal Sonic of those games is a separate one. Another explanation is that this is somehow the result of the time travel shenanigans of Sonic CD.
Metal Sonic is aggressive, power hungry and very cold-hearted. For a long time he has acted more or less as Dr. Eggman's slave, but after turning against his master in Sonic Heroes it became clear he is actually a very controlling person, who views himself as superior to others and wishes to rule over them. He is also completely obsessed with the idea that he is superior to Sonic in every way, and his ultimate desire above all else is proving to the real Sonic that he is better than him, should it be in fighting or just racing, and eventually defeat Sonic once and for all, since it is for this reason that he was created.
It was this desire to defeat Sonic that eventually drove Metal Sonic to rebel in Sonic Heroes, as he claimed this was the reason that he took Dr. Eggman's position and sought out the data from the others to become Metal Overlord: So that he could finally defeat Sonic. In Sonic Heroes he even goes as far as calling Sonic "my loathsome copy", as well as desperately shouting "I am the real Sonic!" when he is defeated by Team Super Sonic. He also says "Sonic, I was created for the sole purpose of destroying you", near the middle of the fight, raising the question as to how Metal Sonic can both believe himself to be the real Sonic and at the same time acknowledge his existence as a mechanical copy of Sonic. This suggests that Metal Sonic's obsession with the real Sonic, and the belief that he is better than him drove him insane in the process and twisted his rational mind, making him think that since he is supposed to be the superior Sonic, it makes him the real Sonic. It can also be thought, however, that Metal Sonic thinks that even though he was created, he believes he's the real Sonic.
Metal Sonic gained some independence in Sonic Heroes, which led to his rebellion against his creator, but that part of him was removed when Dr. Eggman restored him to his robotic slave after these events. Metal Sonic regained his independence, however, in Sonic Free Riders when he goes inside Team Dark's new robot Power Member E-10000B, without even Dr. Eggman knowing it and stealing the data Eggman intended to get for his own nefarious uses.

Note: In Sonic Rivals 2, Metal Sonic is discovered to have a Chaos Emerald stored it inside himself, either for use as a secondary power supply, or as a hiding place to keep it from being discovered.
Being a robotic clone of Sonic, Metal Sonic has access to many of Sonic's powers and abilities. He can utilize the Spin Dash (albeit a far more deadly circular saw variation) and the Homing Attack, and can also jump higher and farther than Sonic, and match or even exceed his speed; though many games actually depict Metal Sonic as being faster than Sonic, it is countered by poor traction and braking abilities (likely stemming from Metal Sonic's tendency to hover above the ground at high speeds).
He can temporarily achieve 4 times the accelerating speed of Sonic, in his early appearances; it is suggested that at this time his systems are overclocked. Metal Sonic also is capable of an attack called the "V. Maximum Overdrive Attack", and while it is active, Metal Sonic can reportedly penetrate any substance. However, the V. Maximum Overdrive attack cannot be sustained for extended periods of time because of its unfavorable cost performance and potential to destroy Metal Sonic himself. In addition, Metal Sonic can also use an area-of-effect attack called Ring Spark Field, but the attack affects his speed, as at least some of the power necessary to engage it is rerouted from systems which he depends on for mobility.
In addition to Sonic's abilities, Metal Sonic has numerous capabilities unique to himself. He can fire laser blasts from the aperture in his abdomen, fly via the use of the jet engine in his midsection, stretch his arms and legs to great lengths and strike from a distance, generate powerful electricity from his body, and generate a diamond-shaped force field (dubbed the "Black Shield") to protect himself.
Arguably, his most powerful and impressive ability is that to scan other characters (much like Emerl), copy their life data into himself, and immediately and flawlessly replicate not only their abilities, but also their physical form to look and sound exactly like them (this is how, in Sonic Heroes, he tricked everyone into believing he was Eggman, and also the reason Team Rose believed Sonic to have Froggy and Chocola with him). His acquired abilities and traits are listed below:
- Chaos Control from Shadow
- Super-strength from Knuckles, Vector, Omega and Big
- Strategic planning from Eggman (maintaining and deploying Eggman's army and fleet)
- A strong sense of freedom (evidenced by his turning on Dr. Eggman in Sonic Heroes) and identity (claiming to be the real Sonic) from Sonic himself (and possibly Shadow).
- Metal Sonic copyed Sonic, Tails, Amy, Fang, Bean, Bark, Espio, and Knuckles' abilities in Sonic the Fighters.
- Metal Sonic copyed Team Sonic, Team Rose, Team Dark, Team Chaotix, and Eggman's abilities in Sonic Heroes.
- Metal Sonic copyed Sonic, Shadow, and Silver's abilities in Sonic Rivals
- Metal Sonic copyed Sonic, Tails, Shadow, Silver, Espio, Knuckles, and Rouge's abilities in Sonic Rivals 2.
- Metal Sonic copyed Team Heroes, Team Babylon, Team Dark, Team Rose, Eggman, Silver, and Blaze's abilities in Sonic Free Riders.
Also as of Sonic the Hedgehog 4: Episode Metal it is revealed that Metal Sonic acquired a special item that boosts his powers and gives him access to incredibly powerful abilities. First he can charge himself to augment his strength, this boost is so potent that when successfully charged it releases a shockwave around himself that is quite damaging. When using this power he glows in a dark aura, and the strength and speed of his Spin Dash is increased, his Spin Dash can be so powerful that it can destroy tracklines up to three times with a single charge. Further boost of this power allows him to perform a Spin Dash so violent that while jumping he ricochets with great speed. He is also capable of using this power to release pillars of lightning that exist for a prolonged period of time.
With the power of the corrupted Chaos Rings, the Dark Rings, Metal can transform into Metal Sonic Kai as seen in Knuckles' Chaotix. This transformation turns Metal Sonic into a gigantic, slightly elongated, red version of himself, while granting him increased strength and power.
Metal Sonic assumed the form of Neo Metal Sonic for the majority of Sonic Heroes, where he used it to disguise himself in order to copy the other teams' data. While most details of Metal Sonic's abilities while in this form remain unknown, it is shown that he is capable of shape-shifting and shooting powerful bolts of lightning from his hands.
Using the data from Team Sonic, Team Rose, Team Dark, Team Chaotix and Chaos, and as well as parts of Eggman's other machines, Neo Metal Sonic can transform himself into a super powerful version of himself called Metal Madness. In this form Metal Sonic possesses a flamethrower, missile launchers and massively increased strength. Eggman states that he is so powerful in this state that they have a slim chance of beating him, even with all seven Chaos Emeralds.
After completing his transformation as Metal Madness, Metal Sonic becomes Metal Overlord. In this form he sprouts wings, thus gaining the ability to fly, the ability to shoot crystals and perform Chaos Control. In this form he becomes so powerful that he is nearly invincible, even to super transformed characters.
Appearances in Other Media
Sonic the Comic
In the United Kingdom's official Sonic publication, Sonic the Comic, "Metal Sonic" was relegated to the character's title, and Sonic's robot double was redubbed with the name of "Metallix" (hence, he was "Metallix, the Metal Sonic").
Metallix first appeared in the magazine's adaptation of Sonic CD, in which it was destroyed by Sonic. However, it was later revealed that this first Metallix was merely one of a vast brotherhood of identical robots, known collectively as the Brotherhood of Metallix. Ruled by a giant red-and-gold Emperor Metallix, the Brotherhood captured the Omni-Viewer, allowing them to travel back in time, and erase Doctor Robotnik from history. Since it had been Robotnik's assistant Grimer who built the Metallix robots, and Robotnik had contributed only a self-destruct mechanism, the Brotherhood was able to conquer Mobius, leaving Sonic in the unenviable position of having to travel back in time and ensure that Robotnik existed. With the time line back in place, Sonic was forced to ally with Robotnik to defeat the Brotherhood of Metallix once and for all.
Various Metal Sonic models has appeared in the Archie Comics, such as Sonic the Hedgehog, Sonic Universe and briefly in Archie Sonic X Issue 40. Metal Sonic first appeared in issue #25, the Sonic CD adaptation, in which he was incorrectly named Mecha Sonic. He raced Sonic as part of one of Robotnik's traps, but was destroyed at the end of the issue.
Metal Sonic returned in the adaptation of the game Knuckles' Chaotix. He was transformed into a giant red version of himself by a "Power Gem," but was destroyed by a similarly empowered Knuckles.
Metal Sonic's next appearance was in a two-part storyline in issues #86 and 87. He had rebuilt himself by the power of the Power Gem embedded in him, and boasted improved powers and a new design. He captured Tails while he was gathering firewood in the forest in which the Freedom Fighters were stranded. Metal Sonic confronted Sonic, then made him race for his friend's life to the top of the soon to erupt Mt. Mobius volcano, where Tails was tied. Despite Metal Sonic's attacks along the way, Sonic made it to the summit of Mt. Mobius just as the lava began to rise. Though it seemed like they were doomed, Sonic and Tails refused to abandon one another, showing Metal Sonic that there was more to life than power. Metal Sonic held back the lava for them and Sonic and Tails managed to escape, but Metal Sonic was destroyed in the effort. (This is similar to the Sonic OVA where Metal Sonic is destroyed at the end by lava)
A year later, a new series of Metal Sonics was re-created from scratch by Eggman, with the first being created as part of a storyline involving a 3-way battle between himself, Shadow, and Sonic. These new Metal Sonics would from then on become fierce foes that Sonic and his allies would confront regularly.
Sonic the Hedgehog: The Movie
Metal Sonic also starred in Sonic the Hedgehog: The Movie as Sonic's main rival. In this movie, they had a mind link and were able to hear each other's thoughts. He mainly communicated in bleeps and other such robot-like noises, and was as depicted being more powerful then Sonic in this incarnation, besting him whenever they fought. Near the end of the movie, Metal Sonic was influenced by Sonic's thoughts and sacrificed himself to save the President and Old Man Owl.
The personality of this Metal Sonic is slightly different than his game counterpart. He seems to be rather sane and acts rather solo than compared with his role as 'second banana' to Dr. Eggman and himself in Sonic Heroes. Nearing the end, he falls into a volcanic precipice after an epic battle with Sonic. Sonic attempts to save him, but Metal does not accept, replying "there is only one Sonic". He is then destroyed in the magma, and this implies that Metal, though he was programmed for evil, is fully sentient and autonomous. It was also stated by Tails that Metal Sonic received Sonic's personality traits and memories when Sonic's data was transferred into Metal Sonic's.
Besides the OVA, Metal Sonic has never made an real appearance in any of the Sonic television series. However, there was an artificial replica of Sonic (which required a pilot to operate) in the episode "Pseudo-Sonic" from Adventures of Sonic the Hedgehog, which the Robotnik from that universe also claimed to be his greatest invention ever (a claim he also made on several other occasions). Metal Sonic was also among the various candidates fans believed to have the red eyes seen at the end of the canceled Sonic the Hedgehog series, before it was revealed by the creator that they belonged to Ixis Naugus.

- "I'll crush you!" - Metal Overlord after picking up one of Eggman's ships in and before throwing at Team Super Sonic in Sonic Heroes.
- "But that was the past. Now you're nothing but a speck of dust to me" - To Super Sonic in Sonic Heroes.
- "See me as I am, no longer afraid of anything! I shall become the ultimate overlord, ruling as the world's most supreme being!" - To Team Super Sonic in Sonic Heroes.
- "Why! I had it all! I am the ultimate overlord, Metal Sonic! I am the real Sonic!" - Metal Overlord after being defeated by Super Sonic, Tails and Knuckles in Sonic Heroes.
- "It's no use....but why can't I defeat you...?" - Neo Metal Sonic question after his defeat before transforming back into Metal Sonic in Sonic Heroes.
- "FACE ME IF YOU WISH TO HAVE THE CHAOS EMERALD." - Classic Metal Sonic before Classic Sonic begins to battle him in Sonic Generations.
- "I WILL BATTLE YOU AS MANY TIMES AS IT IS NECESSARY."- Classic Metal Sonic before you rematch him in Sonic Generations.
- ".........Whoever clears all of the stages first wins." - Metal Sonic before battle in Sonic Pinball Party.
- "There is only one sonic...nic..nic..nic......" - Metal Sonic after he slaps Sonics hand away because he was trying to save him from and before he lost to sonic and melted in lava in Sonic the movie (1999)
- Although Metal Sonic 3.0 appears in Sonic Rivals 2, it is unknown which (if any) of the previous versions of Metal Sonic are versions 1.0 and 2.0. In the Archie universe, the original Metal Sonics made by Dr. Ivo Robotnik was 1.0 and 2.0, and the other Metal Sonics made by his alternate counterpart, Doctor Eggman, were all 3.0.
- Sonic Rivals 2 was the first Sonic game where Metal Sonic has done some heroic deeds.
- GameDaily placed Metal Sonic 13th on their "Top 25 Video Game Robots" list, describing him as Dr. Eggman's "greatest creation" and praising the strength of his abilities.
- In Sonic Heroes, Metal Sonic wants to prove himself to be the "real" Sonic and even greeted his organic counterpart with the words "loathsome copy". This is in contrast to his depiction in Sonic the Hedgehog: The Movie, in which he solemnly accepts his fate with his sole line "There is only one Sonic".
- Though Metal Sonic is playable in Mario and Sonic at the Olympic Winter Games, in the DS version he is also a boss character.
- Metal Sonic's pose during the ending of Sonic the Hedgehog 4 Episode I, looks just like his pose in Mario & Sonic at the Olympic Winter Games.
- Metal Sonic rarely speaks and his voice is only heard during Sonic Heroes, while in all of his transformations (Neo Metal Sonic, Metal Madness, and Metal Overlord, as well as when he is disguised as Eggman). Interestingly, he share's Sonic's voice actor. He also speaks with a text bubble in Sonic Generations, even though it was previously believed that the capability of speech was a Heroes-only ability.
- Metal Sonic's 2D Sonic Channel artwork looks similar to his Sonic Rivals 2 pose.
- Metal Sonic has the most altenate forms of a character that is not a hero.
- Metal Sonic is considered Sonic's first rival in the series.
- Metal Sonic is the most recurring robot in the series, next to E-123 Omega.
- In the game "Spiral Knights", players who purchased a copy of Sonic CD on Steam before January 31st, 2012, received a Metal Sonic costume for their knight. This costume was also available to purchase in-game.
- Metal Sonic is one of four of Eggman's robots who betray their creator, the other three being Gamma, Gemerl, and Omega.
- In Sonic Generations, Metal Sonic is the only rival that doesn't appear in the Center of Time before Modern and Classic Sonic confront the Time Eater (Assuming he was destroyed when Classic Sonic defeated Him), or appearing at the party within completion of the game.
- Another possible explanation for this is that Metal Sonic is Sonic's enemy in addition to rival, so he would not be cheering the Sonics on during the final boss and since he obviously is not Sonic's friend and he would not be at the party either.
- There is evidence to support that he was at one point going to be playable in Sonic the Hedgehog (2006), but at one point was scrapped. Said Evidence can be found here.
- When Metal Sonic in Sonic 4, absorbs the ancient artifact of Lost Labyrinth he somewhat resembles Hyper Metal Sonic when he activated in the OVA.
- In Sonic the Fighters, Metal Sonic is not playable. But by using the Action Replay for Sonic Gems Collection on the GameCube and hd version, he can be playable.
- In Sonic & All-Stars Racing Transformed, he is one of only four characters to drive a ATV, the others are Beat, Knuckles & Joe Musashi.
