A bionic thing/person/device is a creature made of a combination of electronic and biological elements. The term applies equally to an electronic device with biological elements, such as the infamous Terminator, who was a robotic endoskeleton covered in living flesh, and biological elements in a robotic gestalt, like the Robocop or that weird cyclops guy from the Stallone movie Judge Dredd.

Once a plot foil in sci-fi, bionics are a part of modern life, with cochlear implants for the hearing impaired, pacemakers, artificial valves, and stents in human hearts, and various prosthesis for limbs and sundry parts.

(My girlfriend also mentioned the AOL dude, a knockoff of the six million dollar man.)
