1. Darth Vader (StarWars 1977)
Darth Vader or Bad Father?, I think they mention the same person.
2. T-800 (The Terminator 1984)
Followed by T-101 and T-850 (They sure are cyborgs not cellphones:)). The first cyborg who nominated to become US State Governor :).
3. Robocop (Robocop 1987)
Robocop, born of technology is a cyborg, half man/half machine. The future of Law enforcement is here, and he's kicking ass.
4. Steve Austin (The Six Million Dollar Man 1974)
The Six Million Dollar Man, Part Man, Part Machine, All Action. Better, Stronger, Faster!
5. Jammie Sommers (The Bionic Woman 1976)
Jaime Sommers had amplified hearing, a greatly strengthened right arm, and enhanced legs, enabling her to run faster than a speeding car.
6. The Borg (Star Trek 1966)
7. Doctor Octopus (Spider-Man 2 2004)
He has four arms with great strength and highly precise movement, attached to a harness that fit around his body.
8. Sanford Scolex (Inspector Gadget 1983)
His doctor put binoculars, parachute, propeller blades, handcuff, spring legs, and many various mechanical tools into his body during surgery, isn't it medical malpractices? :).
9. Tony Stark (Iron Man 2008)
Wow wow wow the tastiest cyborg hero down so far.
10. Del Spooner (I, Robot 2004)
It's just his left arm but it so powerful. Cyborg vs Robot, it's like handicap guy vs robot :).
