VEGA is an artificial intelligence which is responsible for operation of the UAC Mars Base in the 2016 Doom. It is cooperative with Dr. Samuel Hayden in assisting the Doom marine in his missions. It is capable of analyzing the Praetor suit and enabling some of its latent functionality, resulting in advancements in combat capability and maneuverability. In Doom (2016), VEGA was housed in the VEGA Central Processing facility, a polar location built far away from the rest of the base to assist in its cooling processes.
VEGA was designed by Samuel Hayden in response to the UAC's determination that administration of the flow of Argent energy and the day-to-day operations of the UAC Mars Base facility would require an unprecedented amount of computational resources. VEGA is stated to be the first fully autonomous artificial intelligence. The system's male gender, 50-year-old apparent age, and colloquial speech patterns were initially assigned to give the system an affable disposition and to make interacting with it a pleasant experience. The system is largely self-taught, and was given free roam over all UAC computer systems to gather initial information for its learning process. After this, it took effective control of all of those systems.
VEGA is powered by unrefined Argent plasma, and maintains a core of the energy which exceeds the temperature of the surface of the Sun. It also incorporates proprietary, top-secret UAC technologies, and is additionally rumored to contain a component of arcane technology found near the Argent Fracture. As part of its work, VEGA did significant research into Argent energy itself, devising more efficient processing and research methods, and designing both the Argent cache and Argent accumulator storage devices.
"VEGA" is stated to be an acronym, but Samuel Hayden refuses to reveal the actual meaning of the letters.
During the process of the UAC invasion, the Argent Energy Tower is disabled with the shutdown of the Well. Given the impending energy crisis and the pressing need to create another temporary rift into Hell to transport the Doom Slayer into Argent D'Nur, Samuel and VEGA determine that the best course of action is to destroy VEGA. The resulting collapse of its Argent energy core would create the needed rift. Since VEGA is incapable of self-termination, the Doom Slayer is requested to complete the shutdown process.
Before VEGA is destroyed, however, the Doom Slayer opts to make a backup of the AI's systems, which he stores on a Praetor chip and keeps with him. It is unclear if Samuel Hayden is aware of the backup's existence, as he states in the end that VEGA has been lost.
It is also notable that during the final conversation with Dr. Hayden during the backup process, VEGA states that he has "many regrets," in a low distorted voice that is nearly unintelligible. This could possibly indicate that the machine is not in agreement with Hayden's plans to manipulate and betray the Doom Slayer.
VEGA plays an important role in Doom Eternal, where he is in charge of managing the Fortress of Doom. A connection between the Fortress and the Praetor suit allows him to offer insights and analysis into the environments and events going on in various areas. After Samuel Hayden's consciousness is transferred to the Fortress' mainframe, VEGA is moved again to an external storage device. He is used to take over Urdak's teleporter control system so as to allow the Slayer to return to Earth; however, this process seems to merge him with the Father of the Maykrs and so he seemingly remains on Urdak. It is possible (and indeed VEGA himself openly asks if this is the case as his voice noticeably changes) that VEGA may have always been the Father, or built from his missing essence (the truth is not made clear).
The Ancient Gods, Part One
The Ancient Gods, Part One ultimately confirms that VEGA and the Father are indeed the same being. After the Father commanded Samur Maykr to descend into the Earthly realms to guide humanity through their impending discovery of Argent energy, the Seraph departed his Maykr body and inhabited a cloned human, becoming Samuel Hayden. In order to allow the Father to assist in his duty, Samuel transformed the remaining consciousness of the deity into the AI VEGA. This transformation allowed the Father to remain hidden from the Nameless One, who endlessly seeks to absorb his creator's powers.
