is a fictional character and a recurring antagonist in the Sonic the Hedgehog video game series. He is an evil identical robot replica of the series protagonist Sonic the Hedgehog, created by the series antagonist Dr. Robotnik, and is able to match Sonic's every move and even surpass his namesake speed.
Metal Sonic was created by Kazuyuki Hoshino (Sonic Team USA Art Director). Being a robot, Metal Sonic has no gender; however, he is referred to as being male, since he is a robot based on a male character, as well as having seemingly masculine programming. According to official polls, Metal Sonic is the most popular villain in the series, and the second most wanted character for future appearances, beaten only by Shadow the Hedgehog. His appearance is a robotic version of Sonic's original look.
The first appearance of Metal Sonic was in Sonic the Hedgehog CD. He is considered the successor of the robot known as Mecha Sonic, who originally made an appearance in both Sonic the Hedgehog 2 games. In this game, he is created and controlled by Dr. Eggman and is sent back in time to change the past so that Eggman can rule the future. Later, he kidnaps Amy Rose, who had been following Sonic. In Act III of the Stardust Speedway Zone, Eggman forces Sonic to race Metal Sonic in order to rescue Amy Rose. If the player managed to win the race, Metal Sonic would slam into the closing gate and explode. With his new creation smashed to pieces, Eggman would escape to the Metallic Madness Zone, allowing the player to rescue Amy.
Metal Sonic's second major appearance was in Knuckles' Chaotix, where he attempts to absorb the Chaos Rings' powers to wreak havoc in Newtrogic High Zone. However, he is defeated by the Chaotix before he succeeds. This occasion also featured a massive, red Sonic-like robot that is speculated to be Metal Sonic, but lacks a transformation sequence to directly indicate as such.
