After the whole Neo Metal Sonic incident, you assumed the Freedom Fighters would take care of it easily due to there large number of powerful members. But once you look outside, you hear and see many people screaming and fleeing. Turning to the way they are running from makes you see the Freedom Fighters and even Eggman looking up in the sky with shocked expressions. Looking in their direction leads you Neo Metal Sonic but...Now he takes the form of Metal Sonic like dragon, 300 feet tall, multiple eyes and hands, many wings, and destructive weapons. It soon roars in its deep mechanical voice, before directly speaking to everyone.

Metal Overlord: "All living beings, NEAL BEFORE YOUR MASTER! As I am the true Sonic! I am the true Ultimate Lifeform. I. AM. ALL!" He yells, clearly taking on his strongest form yet. And this was done by himself, no help from Eggman. He has gained power which has surpassed literal demons and ancient gods like Perfect Chaos. The only way to beat him is at least three people using the power of the Chaos Emeralds. But they are still unfound currently.
