Metal Sonic
Metal Sonic (also known as Hyper Metal Sonic and also Metallix amongst some fans in the UK and Metalla in Japan) is the "robotic counterpart" of video game character Sonic the Hedgehog. Being a robot, Metal Sonic has no gender; however, Metal is usually referred to as being male, since he is a robot based on a male character. As well as resembling Sonic, he can also perform Sonic's 'spin dash attack'.

Game history
Early Appearances
The first appearance of Metal Sonic was in Sonic CD for the Sega CD console. In this game, he is under the control of Dr. Robotnik and is is sent back in time to change the past so that Dr. Robotnik can rule the future. Later, he kidnaps Amy Rose, who had been following Sonic. He was defeated in the Stardust Speedway zone.
Metal Sonic´s second major appearance was in Knuckles' Chaotix, where he attempts to absorb the Chaos Rings' powers to wreak havoc in the Carnival Zone but was defeated by the Chaotix before he could.
Metal Sonic had appearances in Sonic Drift 2, Sonic the Fighters,Sonic R, and was a boss character in "Sonic Triple Trouble".
He also starred in the OVA as Sonic's main rival. In the anime, they had a mindlink and were able to hear each other's thoughts. Near the end of the movie, Tails reprogrammed him to be on Sonic's side, but Metal was destroyed soon after.
Mecha/Silver Sonic

Note - Some early material refers to Metal Sonic as Mecha Sonic. This has long since been phased out.
Mecha Sonic, also known as Silver Sonic to many fans in outside Japan, first appeared in Sonic the Hedgehog 2 as one of the final bosses. This 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. In the 8-bit version of Sonic 2 he only had 3 attacks and is defeated in the Scrambled Egg Zone.
Mecha Sonic was later upgraded in Sonic & Knuckles. He appeared to be taller, and the construction of his limbs and face looked different. This version of the robot is usually called Mecha Sonic (instead of Silver Sonic) even by non-Japanese fans, probably cause he is no longer silverish gray in color. There have been much confusion among fans weather this robot really is Mecha Sonic from Sonic the Hedgehog 2, or if it's Metal Sonic or a third robot. But it was, in fact, stated to be Mecha Sonic in the Japanese version of Sonic Jam.
Against Sonic and Tails, Mecha Sonic 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, he 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).
Modern Appearances
Metal Sonic has a cameo in Sonic Adventure , inside a tube in one of Dr. Robotnik's hideouts along with Silver Sonic.
His 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. He can project a black shield to protect himself from the attacks of other characters, but has no special attacks of his own. After that, he had a cameo as an opponent in Sonic Pinball Party's Story Mode. He then appeared as a gift for getting all of the Emblems in the GameCube remake of Sonic Adventure, Sonic Adventure DX: Directors Cut, one could then play time trials as Metal Sonic in Sonic's stages. Metal Sonic essentially acted as an alternate skin for Sonic.
His latest appearance is as the main antagonist in Sonic Heroes. Assuming the guise of Doctor Eggman, he copies the physical data (and/or abilities) of Sonic, Shadow, Froggy and Chocola (a chao that was sought by Team Rose) to assume his ultimate form, Metal Madness, and later Metal Overlord. This transformation was made possible with the power of Chaos, the water-like creature from Sonic Adventure. 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). He manages to achieve this through the use of Chocola, since Chao have a distinct connection to Chaos, and Froggy, who periodically had Chaos' tail in Sonic Adventure. After he is defeated by Team Super Sonic in his Metal Overlord form, he reverts to his original form.
It is not yet known if he will return in Shadow the Hedgehog (video game)
Sonic the Comic
In the United Kingdom's official Sonic publication, Sonic the Comic, Metal Sonic was introduced in the magazine's adaptation of Sonic CD, an issue entitled "The Sonic Terminator." Relegating "Metal Sonic" to the character's title, Sonic's robot double was redubbed with the less-clunky moniker of "Metallix" (hence, he was "Metallix, the Metal Sonic"). Metallix lured Sonic to the Miracle Planet by capturing Amy Rose, and in the course of the adventure, Sonic travelled back in time to prevent Doctor Eggman from cyberforming the planet, thereby erasing Metallix, who had used the planet as a power source, from the timeline.
The Brotherhood of Metallix
A new model of Metallix appeared during the comic's adaptation of Sonic and Knuckles, stealing the Master Emerald for Robotnik to use as the power core of his new Death Egg. Metallix drew power from the emerald and incapacitated Knuckles, but Sonic was able to destroy him by using the emerald's power to become Super Sonic. Before he died, the new Metallix revealed that both he and the original Metallix were members of an elite brotherhood.
This brotherhood soon revealed itself when Knuckles was accidentally transported into the Special Zone and encountered Chaotix. Operating out of Robotnik's abandoned Egg Fortress in the Special Zone, the Brotherhood of Metallix - innumerable Metallixes identical to the original, ruled over by an giant red and gold Emperor - had been charged with producing the ultimate badnik version of Sonic, but had developed their own plans and goals. With the help of the turncoat Chaotix member, Nack the Weasel, the Brotherhood of Metallix captured the Omni-Viewer, Chaotix's sentient, space-time transporter. With Knuckles's help, Chaotix were able to retrieve the Omni-Viewer, and though it appeared that the Metallixes had been defeated, they in fact survived, and had copied the Omni-Viewer for their own purposes.
Final battle
In their next move, the Brotherhood captured Grimer, Doctor Robotnik's chief scientist, who had created the Metallix design in the first place. They charged him with building the Alpha Device, a device that began to cyberform the Miracle Planet once again. Sonic's attempt to stop the plan apparently succeeded, but his ally, Porker Lewis, was trapped on the Miracle Planet when it vanished from Mobius orbit in its usual pattern. During that month, the Metallixes reasserted themselves, captured Porker and completed the cyberforming of the planet. A Metallix, disguised as Porker, was left to stand guard as the Metallixes departed into Mobius' past with their copy of the Omni-Viewer, and when they returned, they encountered Sonic and Chaotix, who had come to investigate. But then the terrifying truth became apparent - the Metallixes had changed history, and Mobius had become a city-planet, covered with filthy industry, where surviving Mobians lived underground.
The reason for the change soon became apparent, as Sonic and Chaotix attempted to fix the timeline by using the real Omni-Viewer - the Brotherhood of Metallix had travelled back in time to the point of Doctor Robotnik's creation, and removed from the fridge the rotten egg that would transform Ovi Kintobor into Ivo Robotnik. Kintobor never became Robotnik, and the Metallixes, created by Grimer alone, ruled the planet. Retrieving the egg, Sonic and Chaotix returned to Kintobor's lab and replaced it, and then, as Kintobor held it in his hand, Sonic yanked a cable to trip him up, triggering the chain of events that turned him into Doctor Robotnik. Despite the disturbing revelation that he was responsible for creating the greatest evil on Mobius, Sonic returned to the present with Chaotix, where the robots still held control of the Miracle Planet. Forced into an alliance with Doctor Robotnik, Sonic retrieved a device from the villain that deactivated all the Metallixes in a pitched final battle.
Archie Sonic the Hedgehog Comic
Though it was not his first true appearance, a Metal Sonic-like robot appeared in the comic's early issues. He was known as Pseudo Sonic, and was destroyed by the end of the issue. Psuedo Sonic also appeared in an episode of Adventures of Sonic the Hedgehog.
Metal Sonic first appeared in the comic's first "25 issue anniversary", the Sonic CD adaption. Here, he raced Sonic as part of Dr. Robotnik's trap, but was destroyed at the end of the issue.
Metal Sonic would later return in the series' Knuckles' Chaotix adaptation. Here, he would be transformed into a giant red version of himself by an item known as a Power Gem, before being destroyed by a similarly empowered Knuckles the Echidna.
Metal Sonic's next appearance would follow the Sonic Adventure adaption, in a two-part story where he would ambush Sonic and Tails. He had rebuilt himself, using the power gem that had empowered him as a power source, and boasted a new design that included an arm cannon. After kidnapping Tails, Metal Sonic made Sonic race for his friend's life towards the Mt. Mobius volcano. However, ultimately, it was Sonic's concern for Tails that showed Metal Sonic that he was wrong, and ultimately saved the two of them from the erupting volcano.
A new Metal Sonic created from scratch by Robotnik appeared in recent comic issues, as part of a storyline involving a 3-way battle between himself, Shadow, and Sonic.
Silver Sonic
Silver Sonic appeared as a seperate robot in Archie's Death Egg Saga mini-series. Here, he was portrayed as a gigantic lumbering robotic version of Sonic, but after defeating it, Sonic crawled inside and took control of it in order to battle Robotnik in his own battle armor. Sonic abandoned the shell when he escaped the Death Egg.
Robotnik would create a smaller, more individualized version of Silver Sonic following the Sonic Adventure adaption, where he would use it to attack Station Square. This version was again defeated by Sonic, but this time, he would be reprogrammed as Station Square's defender. Unfortunately, he would later be destroyed by Shadow in the Sonic Adventure 2 adaptation.
Mecha Sonic
In the Archie comics, Mecha Sonic would refer to Sonic when he was roboticized in issue #39 and the following Mecha Madness special. After being captured by Nack the Weasel, Sonic would be roboticized and turned on the village of Knothole. Despite going up against both Bunnie Rabbot and Knuckles, Mecha Sonic managed to destroy large portions of the city, leaving the Freedom Fighters with only one choice. Knuckles roboticized himself, using a nueral overrider to retain his will, and fought Mecha Sonic. Ultimately, the fight went to Robotropolis, setting of a nuclear explosion that Mecha Sonic saved Knuckles from at the last minute. Sonic would later be restored by the power of his 1 Billionth collected Power Ring, and though he was put on trial for his crimes as Mecha Sonic, he would clear his name.
Mecha Sonic made a shorter appearance later on when he and Tails were transformed into robots by an alien race, to fight Dr. Robotnik and Snively (who had been transformed back into organics) in order to prove which was superior - robots or organics.
