"Sonic... I was created for the sole purpose of destroying you. But I can never seem to defeat you! That is why I transformed my own body with my own hands!""
Metal Sonic, Sonic Heroes

Not to be confused with Mecha Sonic.

Metal Sonic (メタルソニック Metaru Sonikku) is the secondary antagonist of the Sonic the Hedgehog series. He is a robotic doppelgänger of Sonic the Hedgehog created by Dr. Eggman to destroy the blue blur once and for all.

Why He's Metal (pun entirely intended)

  1. He's the first character ever to match Sonic in nearly every way.
  2. He's also the first robot in the franchise to speak and think by himself (followed by E-102 Gamma and E-123 Omega).
  3. His usual muteness may be a bit lame, but is also a clever move to emphasize how he's an antonym to Sonic, since it contradicts his talkativeness and sass.
  4. While he doesn't play mind games often, he may be able to get into his enemies' heads. In his first encounter with Sonic for example, he kidnapped Amy Rose, completely untouchable.
  5. Like his creator, he doesn't stop at nothing to defeat his organic rival no matter what.
  6. He has a fair share of sick transformations, like Metal Sonic Kai (a.k.a. World Entrance Level 2) from Knuckles Chaotix, Super Metal Sonic, from Sonic Mania Adventures and of course, Metal Overlord from Sonic Heroes.
  7. Not only he is able to copy Sonic, but also anyone he wants.
  8. His cold, heartless, spiteful and menacing glare.
  9. Despite being dead set on destroying his enemies, Metal is perfectly able to work together with the heroes in some occasions, again, similarly to Eggman.
  10. Also, despite his belief that he's the "real Sonic", he does realize that's not true and sacrifices himself after being heavily damaged while saving the South Island President and Old Man Owl.
  11. He was the responsible for the big plot twist in the last story of Heroes: the Chaotix discover that Eggman was locked up on isolation the whole time, and Metal (disguised as Eggman) was the one pulling the strings.
  12. Like other Sonic characters, he has plenty of bangers to call them his theme songs, such as Never Let It Go, What I'm Made Of and a song which he shares his name with in the Virtual Sonic album.

Bad Qualities

  1. He can be very reckless when it comes to achieve his goals, like when he fought Super Sonic in his Metal Overlord form, and when he performs attacks that can damage him, like the V. Maximum Overdrive Attack and the Ring Spark Field.
  2. His boss fights in more recent games are all too resemblant to his original boss fight in Sonic CD (except his second fight in Sonic 4: Episode 2 and his third phase in Mania after the Plus update).
  3. Even though he knows he's a robot copy, he still refers to Sonic as his "loathsome copy", which makes no sense.

"All life form data... successfully copied." - Sonic Heroes

"All living things kneel before your master!" - Sonic Heroes

"Even the Ultimate Life Form can't stop me!" - Sonic Heroes

"Long time no see, Sonic! My loathsome copy!" - Sonic Heroes

"It's no use... but why can't I defeat you?" - Sonic Heroes



  • Metal isn't the first/only robotic Sonic created by Sega. Others include Silver Sonic, from Sonic 2, and Mecha Sonic from Sonic & Knuckles, as well as the mini Silver Sonics from the 8-bit version of Sonic 2, the Virtual Hedgehogs from Sonic Colors and Lost World and Cyborg Sonic from Sonic Boom.
  • Unlike Sonic's subsequent rivals, Metal never becomes a permanent ally to him. They do, however, team up on the 29th issue of the IDW comics.
