Metal Sonic first appeared as Dr Eggman's robotic counterpart to Sonic the Hedgehog in the Sonic games, built to match Sonic's speed with a cold, mechanical personality.

This affirmative line spread because it works outside its original context as a universal robot yes, useful for jokes about AI, machines following orders, and emotionless agreement in edits, streams and group chats.
