But yeah, I see no difference in a machine controlled my Eggman using Chaos Emeralds and robots doing the same. There's also multiple examples of this: Mecha Sonic, Emerl, Phi, Gemerl, Chaos Gamma, and the multiplayer Shadow Androids (although their canonicity is questionable). I am curious why Dr. Eggman never recreated the same upgrade used in Mecha Sonic to give to Metal Sonic for super transformation.

Unless Super Mecha Sonic is actually Mecha Sonic being super-heated.
