Cyclop is an artificial intelligence inside the Fort Charles in the 1987–1996 animated TV-series. It appears in the episode The Big Rip-Off, reprogrammed by Shredder on remote from inside the Technodrome. When reprogrammed, the Cyclop turns the equipment of the American Army against them.
It's name comes from that the camera resembles an eye, and cyclops were one-eyed creatures from Ancient Greek mythology.
