Is Sonic the Hedgehog robot

Answer 1

No, Sonic the Hedgehog is not a robot. He simply is a fictional video game character who grew popular over the years. However, in some games and television shows, Dr. Robotnik creates a robotic replica of Sonic with his bare hands, calling it Metal Sonic. Metal Sonic had superspeed and almost all of Sonic's powers. His only flaw was that he was misunderstood, which turns Metal Sonic into Metal Madness for the final boss of Sonic Heroes the game.
