Metal Sonic was teased as a new villain for <em>Sonic the Hedgehog 4</em>, as seen in <em>Sonic 3's</em> post-credits scene. One of Doctor Robotnik's most powerful and dangerous creations, I think it would be very cool if Jim Carrey served as the voice of Metal Sonic. It would be an absolutely hilarious and awesome way to keep the actor in the franchise, especially after Robotnik's apparent death aboard the Eclipse Cannon.
