Some researchers are finding which parts of the central nervous system work best to control robot arms. Modern day science has not advanced to the point where you can have giant robot arms attached to your back, but we do know it's not completely impossible. Then “Doc Oc” controls his robot arms with his own thoughts! Of course, things go wrong and the machine arms start to control him, making him a villain that Spider-man must stop.
He attaches them to his back so he can control them from his spinal cord. Octopus is a scientist who invents four mechanical, octopus-like arms. A great example of this comes from the movie Spider-Man 2.
