The idea of a Sonic robot turning good sounds interesting on paper, and I don't mind it happening with minor Sonic robots like Silver Sonic 2.0, but did they have to make a redemption arc for the one supposedly from Sonic CD? It couldn't have been a defective model or something? There were so many Metal Sonics to choose from, and they picked the most iconic. I just have no idea why they did this to the OG Metal Sonic.
