Metal Sonic first appeared in Sonic CD in 1993 as Dr Robotnik's robotic counterpart to Sonic the Hedgehog, designed to match his speed and attitude. The character returned across later Sega games, cartoons and comics, gaining a cult following for his silent, threatening design and distorted voice effects. Short voice clips labelled SDIYBT circulated on fan soundboards and in YouTube edits, where the second version became a reusable reaction for rival reveals, robot characters and nostalgic Sonic memes shared by gaming communities.

Metal Sonic SDIYBT 2 is a robotic voice clip of Eggman's metallic Sonic rival from the Sonic games, used for villain reveals and gaming edits.
This clip features the cold, robotic voice of Metal Sonic, delivered with heavy distortion, metallic echo and a menacing flattened tone. The SDIYBT 2 version runs longer than a simple sting, letting the synthetic speech build tension before it cuts off. It sounds like a machine imitating a hero, which makes it unsettling and instantly recognisable to Sonic fans. Viewers hear it as a warning that a rival has arrived, and the artificial delivery turns an ordinary line into a villain moment that feels both nostalgic and threatening in edits and gameplay videos online for fans everywhere.
