Sonic the Hedgehog is a popular video game character known for his incredible speed and agility. He is not a robot but a anthropomorphized green hedgehog with superhuman abilities, including the ability to run faster than the speed of sound.
However, there are robot versions of Sonic in some games and media. For example, in the Sonic the Hedgehog video game series, there are several cyborg enemies that Sonic must defeat, including Metal Sonic, a cyborg version of Sonic himself. Additionally, in the Sonic the Hedgehog animated television series, there is a character named Sonic the Hedgehog (or “Sonic SatAM”), who is a cyborg version of Sonic created by Dr. Robotnik.
