Cyclops

The Cyclops also known as Mechanoid is a character that appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. It was a tall, Overlander-shaped mechanoid of unknown origins with a single optic sensor similar to a giant eye.

History
Sally Acorn encountered the Cyclops while on her soul-quest from her late mentor Julayla Chipmunk, in the Forbidden Zone of Mobius. A scan of the machine by NICOLE, after Cyclops proved to be able to impervious to Sonic the Hedgehog's attacks, revealed that its targeting system was entirely motion-based. Sonic then walked up to the robot and stood perfectly still, whereupon the Cyclops went back into standby mode with no target to follow, and allowed the Knothole Freedom Fighters to pass safely.
