Silver Sonic is the secondary antagonist in Sonic the Hedgehog 2. He is the first robotic Sonic replica created by Dr. Robotnik that appears as the first boss of the Death Egg. He is also known as Mecha Sonic.
Silver Sonic's appearance varies throughout the years, but for the most part, he is a robotic version of Sonic with a silver gray paint job, bright orange feet, and a glowing eye.
Like most of Dr. Robotnik's creations, Silver Sonic is programmed with a very obedient personality. He is willing to take direct orders from his master and will execute them without hesitation.
