Metal Sonic's Role In Sonic The Hedgehog 4 Can Finally Bring A Major Sonic Concept To The Big Screen

Metal Sonic being included in Sonic the Hedgehog 4 means that a concept from the comics can finally be included in the movie series. The upcoming Sonic the Hedgehog 4 will include characters such as Sonic, Knuckles, Tails, as well as Amy Rose, who was introduced in the post-credits scene of Sonic 3. While Amy Rose will likely join Team Sonic, Metal Sonic was also introduced at the end of the third movie and will seemingly be the main villain of the fourth film.
