Metal Sonic was created by Sega as Sonic's robotic rival, first appearing in Sonic CD in 1993 as a machine built by Dr Eggman to match Sonic's speed. The faker insult became central to their rivalry because both characters accuse the other of being the imitation. Short voice clips like this spread through soundboards, fan edits and gaming meme pages where Sonic fans reuse rival lines out of context. It remains popular because the dynamic is instantly understood, even by viewers who have never played the original games.
