Super Mario Bros. Z Mecha Sonic character

This is Mecha Sonic. He is a mecha version of Sonic. He is a dangerous villain. Let me tell you the story. (coughing to sound good) Once, there was a robot Sonic named Metal Sonic. He disobeyed Dr. Eggman's orders and connected himself to Eggman's Metal Sonic prototypes and destroyed the Death Egg as Mecha Sonic. Get it now?
