An evil, ultra-high performance, very advanced Badnik version of [Sonic the Hedgehog](https://anilist.co/character/2882) that was created as a secret weapon by [Dr. Eggman](https://anilist.co/character/6672) for the sole purpose of destroying the blue hedgehog. Modeled with extreme accuracy after Sonic, Metal Sonic not only resembles his organic doppelgänger, but can also imitate his moves and achieve speeds matching and even exceeding the hedgehog's own. The brainchild of Eggman, he is by far his greatest creation and one of his "magnum opuses". First deployed during the Little Planet incident, Metal Sonic confronted Sonic in battle and lost, though he would repeatedly return to challenge Sonic and his allies as Eggman's "too-sharp sword".

When Dr. Eggman (Robotnik in the US version) holds the president and his daughter hostage, Sonic must comply to the evil scientist's demand of going to Eggmanland to stop Black Eggman and deactivate the city's generator before it reaches critical mass. Little does Sonic know that it's a trap to activate Hyper Metal Sonic, a robot counterpart built by Eggman to destroy our hero.
