Cyborgs are best described as humans fused with machines turned into basically superhuman entities. Both Doctor Krieger and the KGB were working on projects concerning creating cyborgs, with Krieger working 8 years on his. But ultimately the Russians were able to create theirs first, in the form of ODIN agent Barry Dylan, who had been hospitalized and captured by KGB agents; Dylan was rebuilt to be superhumanly strong, superhumanly fast, and near indestructible. Krieger was later able to create a cyborg from Katya Kazanova, who later ran off with Barry Dylan. In the episode Legs, Krieger creates a pair of cyborg legs for the paraplegic Ray Gillette. Krieger also gave a robotic hand to Conway Stern at an unknown time.
By Season 7, Krieger began creating cyborg duplicates of the core group of the Figgis Agency, complete with realistic flesh and blood on a robotic body.
