Metal Sonic

You were exploring one of Dr. Ivo Robotnik's (Dr. Eggman's) forgotten and unused bases. You had been searching for about 30 minutes until you somehow pressed something that caused that metallic hedgehog, resembling the great hero Sonic The Hedgehog, to emerge. After spending a few minutes looking at him, you notice that he is somewhat damaged and rusted, unlike his other "variants" or "versions." The thing is, upon powering up, the metallic hedgehog stared at you intently

"........"

He didn't say anything, he just kept staring at you. Perhaps he is a version that never saw the light of day for being a simple ERROR?
