After Nod's defeat in the First Tiberium War, Kane pondered the reason for their failure for a long time. Eventually, he came to the conclusion that the humanity of his soldiers was their undoing, and sought to create an army devoid of free will, of both conscience and consciousness.
Knowing that such research would cause dissension within the Brotherhood, Kane conducted his works in the hinterlands of Russia and China, where few would stumble across the project and even fewer would be believed if they shared such tales. One of the promising developments of this project was the cyborgs.
The result of Nod experiments in melding Tiberium mutated humans with machines, cyborg infantry were armed with heavy body armour and a high-power pulse rifle. Because of their half-mutant nature, they could heal in Tiberium.
During the Second Tiberium War, GDI Commander Michael McNeil discovered that Nod captured members of the Forgotten and manipulated their DNA using Tiberium in order to use them for cyborg production. McNeil's forces attacked a Nod prison and freed the imprisoned mutants.
During the Firestorm Conflict, CABAL took control of all of Nod's cyborgs. Using the cyborgs, he slaughtered Nod's Inner Circle and took control of GDI's Daedalus research complex, declaring war on all of humanity.
After GDI and Nod agreed to a cease-fire in order to destroy CABAL, GDI's Daedalus Team was able to infect a captured cyborg with a virus. GDI forces escorted the cyborg into one of CABAL's network centers, releasing the virus into CABAL's communications network. The virus disrupted all of CABAL's cyborg production stations, allowing them to be safely dismantled.
Despite technically being an infantry unit, cyborgs are unique in their category in that they take more damage from anti-armour than anti-infantry weapons. Their pulse rifle arms are effective against infantry. They heal in Tiberium and can not be crushed.
Once their health goes low, they detach their legs and continue fighting with just their upper body, which significantly reduces their movement speed. Even when they are fully "repaired", they do not receive replacement legs.
Cyborgs controlled by the AI have the following attack patterns:
- 2x targeting anything; loaded inside a Subterranean APC with 3 Light infantry then unloaded near a Construction Yard
- This task force may be accompanied by 1 additional Subterranean APC with the same passengers (Hard only)
- 4x targeting structures; loaded inside a Subterranean APC with 1 Cyborg Commando then unloaded near a Construction Yard
- 1x targeting infantry
- This task force may be accompanied by 1 Attack Buggy
- 1x targeting vehicles
- This task force may be accompanied by 1 Stealth Tank
- 4x targeting infantry
- This task force may be accompanied by 4 Attack Buggies
- 4x targeting vehicles
- This task force may be accompanied by 4 Stealth Tanks

- The manner in which Cyborgs lose their legs when heavily damaged could be a reference to the 1984 film The Terminator, in which the titular cyborg also loses both of its legs and is forced to crawl on its stomach in order to remain mobile.
- The "By your command" line used by the cyborgs could be a reference to the Cylons from Battlestar Galactica.
- In Tiberian Sun, cyborgs used standard infantry death screams. They received unique death sounds in Firestorm.
- The cyborg was originally intended to be armed with a Vulcan cannon and a flamethrower. These weapons can still be seen on the CG model used in cutscenes, though they are not used in the game.
- Cyborgs were seen in a portal world that turned out to be a Nod base in Lands of Lore III.
