You guys need to play Sonic the Hedgehog 4: Episode Metal. In that game it CLEARLY states what happened to the ORIGINAL Metal, from Sonic CD. In that game, it is revealed that at the end of that race where Eggman lasers Metal, he was not destroyed, but was left crippled and barely functional on Little Planet. When it came back in Episode Metal, Eggman went to Little Planet and discovered the wrecked Metal. He brought Metal back and repaired him, and the rest of the game let's you play as Metal Sonic.

If you can't play it, look it up.
