Metal Sonic is Sonic the Hedgehog's robotic rival, created as a mechanical counterpart to Sonic and long used as one of the series' main antagonists. Short voice lines from the character are widely clipped for edits because the cold, synthetic delivery is instantly recognisable to Sonic fans. This particular declaration spread through gaming soundboards and meme edits where a character claims to outclass another. Its brevity and confident tone have kept it in use for rival reveals, versus edits and jokes about an improved or superior version replacing the original.
