Metal Sonic was created by Dr. Eggman (also known as Dr. Robotnik) in the Sonic the Hedgehog series.

In the Sonic games

  • In the classic canon, Metal Sonic is a robot copy of Sonic built by Dr. Eggman specifically to defeat him.
  • He first appears in Sonic CD , where Eggman sends him to kidnap Amy Rose and race Sonic in Stardust Speedway.

Behind-the-scenes creator

  • The in‑universe creator is Dr. Eggman, but the character’s design was done by Kazuyuki Hoshino , who was tasked with making a powerful rival for Sonic in Sonic CD.
  • Hoshino’s brief included making Metal Sonic look sleek and menacing , which led to his pointed silhouette, red eyes, and jet engine.
