I was gonna say Metal Sonic is the strongest robot but then I remember a certain robot: Emerl. Emerl isn't just the strongest robot, he's the most powerful force to appear in the series. He's always learning! He can copy powers, enhance them and preform combos using different fighting styles. Metal Sonic may have turned into a being more powerful than Perfect Chaos (who's power is infinite) but Emerl could've done the same and more. Emerl could actually combo Perfect Chaos' attacks with Boost or something.

In short: Emerl wins. Everything.
