Considered to be the most significant marker of success in the development of Argent-Organic research, the Cyberdemon is the flagship creation of the Lazarus Project. The symbiotic union of a Baalgar demon found during the second Project Lazarus Manned Expedition (MTC 2148/177) and an Argent Accumulator, this beast is capable of withstanding so much punishment that the creature must be kept in permanent suspended animation. Repeated attempts to subdue the beast prove unsuccessful as when exhausted, the Cyberdemon simply replenishes its life force from the Accumulator and attacks again with greater ferocity. Only by removing the Argent implant can the beast be restrained. The Cyberdemon remains in stasis until a suitable method of control can be found.

The Corrax tablets discovered during the UAC Automated Survey of 2143 mention an ancient battle in the Titan's Realm during the third age. An expedition to the plains recovered several relics including the petrified remains of a massive shadow lord believed to be an ancient Baalgar demon. Researchers in the Lazarus Labs began work on piecing the creature back together. At first the project mandate was to construct an educational and inspirational exhibit. However, the focus quickly shifted when an attempt to meld the petrified tissue uncovered that exposure to small doses of plasmatic Argent Energy would reanimate the relic. The potential of creating living, growing tissue from the relic and the lure of an ultimate battle demon was too enticing to - pass up. The project team quickly shifted direction and began work on melding the ancient remains with high tech weaponry.

During the Cyberdemon Reanimation Project, the beast was kept alive by controlling the amount of plasmatic Argent Energy it retrieved. This kept the beast in an effectively "brain-dead" state while additional components were cybernetically implanted. A neural pathway was created between the creature's brain and the Argent Accumulator, allowing the creature to administer Argent power to any part of its body as needed. In hindsight, this neural pathway was a mistake as once the pathway was activated the dormant beast immediately administered an Argent surge to the medulla oblongata, which allowed it to restore motor function. Once active, the circulatory system quickly restored and the beast achieved full motor function within a few minutes. It is only through the bravery of Follower Jacobson that the beast was contained. Follower Jacobson willingly gave his own life as bait when he lured the giant Cyberdemon into holding pen 6, where it could be contained. Unfortunately, there was no way to retrieve Jacobson once the doors has been bolted, and he was sacrificed.
A report following the incident suggested that this act was not instinct by the Cyberdemon, but rather a suggestion of a greater intelligence governing the will of any creature demon borne - a "mastermind" of sorts. Research on this theory continues.
