"[Commonly known as "Silver Sonic,"] Mecha Sonic is the first boss of the Death Egg Zone in Sonic the Hedgehog 2. This boss has to be hit eight times in order to be defeated so the player can proceed to the Death Egg Robot.'


In Sonic the Hedgehog 2, Mecha Sonic is the first line of defense aboard the Death Egg and it is modeled after Sonic the Hedgehog and his abilities. The robot model is bulky but combat-capable with saw-blade quills, rocket boosters and a metallic spikeball-version of the Spin Attack." -- Sonic the Hedgehog Wiki



Debut: "Sonic the Hedgehog 2 [16-bit]" (1992)
