Silver Sonic

Silver Sonic III, also known as Silver Sonic v3.0, was one of many robotic duplicates of Sonic the Hedgehog created by Dr. Eggman. A modified and larger version of Silver Sonic v2.0, Silver Sonic III was sent out to attack the invaders of the Death Egg Mark 2 that it was guarding. Similar to the first model, it posses the ability to spin into a ball like Sonic but it's massive size is compensated by its ability to engage the blue hedgehog in fierce hand-to-hand combat while deflecting most of Sonic's attacks.

Guardian of the Death Egg Mark 2
After Dr. Eggman launched his EggDome into the sky as the new Death Egg Mark 2, Sonic the Hedgehog and Princess Sally Acorn successfully invaded the gargantuan station. Dr. Eggman revealed to his assistants, Snively Robotnik and Lien-Da, that he had planned on them invading. He then told the two through a speaker that, in order to have an audience with him, they would have to prove that they still were a challenge. Silver Sonic v3.0 then busted through the elevator that they had taken, and Sonic began his battle with the giant robotic version of himself. The battle seemed to partly be a distraction, and Dr. Eggman then launched his new weapon on Mobius while simultaneously shooting down Sally with another weapon. (StH: #225)

Personality
Silver Sonic v3.0 did not have any personality. It bursted through a tiny entrance that was an elevator and proceeded to fight Sonic the Hedgehog without hesitation. This robot is most likely just a mindless weapon. (StH: #225)
