Dark Lord

The Nameless One, also called Davoth, the Dark Lord and the Lord of the Fourth Age, is the ruler of Hell. He first occurs in Doom (2016) in the form of a demonic voice, and is first seen at the end of The Ancient Gods, Part One when he is forced to assume physical form and shown to be almost identical in appearance to the Doom Slayer.

Originally believed to be a creation of the Father, it was revealed in The Ancient Gods, Part Two that the Nameless One was the first being and creator of the Father, the Maykrs and the Slayer. His lieutenants are the Archdemons, who enforce his will unquestioningly.

Origin and betrayal
The Nameless One originated as Davoth, ruler of the realm of Jekkad which preceded all other worlds. Although Jekkad was considered a paradise, Davoth sought to grant his people the gift of immortality as he was Jekkad's only immortal inhabitant; when his own efforts failed, Davoth created the Maykrs and the Father to devise a solution as their machine minds could work on the problem in unison. Although the Maykrs eventually succeeded, they deemed the knowledge too dangerous to share with Davoth as they had concluded that he would eventually become a threat to all of existence. The Maykrs worked together to seal Davoth and Jekkad away, then rewrote their history to portray the Father as their creator and Davoth as his wayward servant. Angered by this perceived betrayal, Davoth was consumed by vengeance and gradually warped into the Nameless One; in turn, Jekkad became a realm of chaos and evil that in time would come to be known as Hell.

In time, the Nameless One and his legions of demons managed to reach into other worlds and conquer them. As the conquest continued, the Father confronted the Nameless One and tore out his life sphere, preventing him from taking a physical form. The Father was reluctant to completely destroy his creator and instead had the life sphere stored in Ingmore's Sanctum high above the Blood Swamps; he then had his own life sphere stored alongside it. Although the Nameless One could not lead his armies in person, he continued to command them through dark whispers and was able to influence the minds of others, particularly those who were susceptible to corruption. This power allowed the Nameless One to initiate a plot to destroy those who had betrayed him, using a weapon that they themselves would create.

Creating the Slayer
At some point after Hell's alliance with the Maykrs began, the Nameless One planted the prophecy of a "chosen one" in the Khan Maykr's mind - an unknown being who would rise to threaten her rule. Eager to destroy this perceived threat, the Khan directed the construction of the Divinity Machine using a fragment of the Nameless One which had been stored by the Father in the coffins of Urdak, hoping that the machine would identify the chosen one before they became a threat. When Taras Nabad came under siege, the Nameless One planted visions and seditious thoughts in Samur Maykr's mind to convince him that the Khan was leading her people to ruin. Unknowingly compelled by the Nameless One, Samur released an imprisoned stranger and placed him in the Divinity Machine, reversing its polarity to empower the stranger and turn him into what would become the Doom Slayer.

Doom (2016)
Prior to the events of Doom (2016), the voice of the Nameless One contacted Olivia Pierce and offered to ease her constant pain in exchange for her assistance in opening a portal to Hell on Mars. During the game, the same voice is heard threatening her over her failure to keep the Slayer from being reawakened, and repeatedly urges the demons to oppose the Slayer during his excursions into Hell.

Doom Eternal
In The Ancient Gods, Part One, the Slayer travels to Ingmore's Sanctum and retrieves the Nameless One's life sphere, intending to bring it to the Luminarium in Urdak in order to force him to take a physical form; the Codex states that the Nameless One can only be destroyed when he has a physical body, but should this happen then every demon outside of Hell would be immediately destroyed as their connection to their reality is severed. When the Nameless One is restored, he is revealed to be identical in appearance to the Slayer, even bearing the Slayer's mark on his back. The Father states that "he is you [the Slayer], in their world" and that the Nameless One is not so much a king as he is a warrior, the only being strong enough to control Hell.

Part Two follows on immediately from Part One with the Slayer trying to shoot the Nameless One, which has no effect as the Luminarium forbids combat. The Nameless One tells the Slayer to face him at Immora before departing through a slipgate; by the time the Slayer reaches Immora, the Nameless One has gathered an army of demons and is wearing a large red suit of power armor in the shape of a demon, fitted with two plasma cannons, a grenade launcher and an energy sword and shield. After fighting through the city, the Slayer reaches the Nameless One's throne room and challenges him to ritual combat - during the battle, the Nameless One reveals that he was the first being (which the Father confirms following a demand from the Nameless One), and was betrayed and sealed away by his creations. Despite knowing he has been lied to by the Father, the Slayer defeats the Nameless One and kills him by stabbing the Doomblade into the artifact on his chest, causing his life sphere to be released and to explode.

Codex entries from Part Two confirm that the Nameless One foresaw that the Slayer would pursue and destroy the Khan Maykr once her alliance with Hell was exposed; she would be destroyed by a weapon she had helped create, giving the Nameless One the vengeance he sought. Because of Samur's actions in hiding the Father, the Nameless One also intended for the Slayer to destroy him as well. The Nameless One knew that he would eventually have to face his creation, but intended to meet the challenge instead of fleeing.

Tactical analysis
The Nameless One normally attacks with a plasma cannon at range, and tries to hit you with an energy sword up-close - it is important to dodge his melee attacks as much as possible, as successful melee blows will regenerate the Nameless One's health based on how much damage is inflicted on the Slayer. The Nameless One has five health bars; each time his health is depleted, perform a glory kill on him to begin the next phase of the fight.

Fighting the Nameless One is similar to battling a marauder; he normally carries a shield that deflects incoming fire, but will drop the shield momentarily when he performs a particular melee attack. To damage the Nameless One you must get close and wait for him to turn away and flash green; attacking at this moment will stun the Nameless One for a few seconds, and you should immediately follow up with a slam from the Sentinel Hammer to keep him stunned for longer and give you more time to deplete his health; quick-switching between the super shotgun and ballista is a good way to deal significant damage. If you get close to the Nameless One and he readies a melee attack but does not flash green, dash away immediately - attacking when the Nameless One is not vulnerable will also cause him to regain health.

Throughout the fight, ammo, armor and health are scattered around the arena; if you need more supplies quickly, use the flame belch and chainsaw on the zombies around the arena to replenish yourself. The Nameless One can also summon wolves that each drop half a hammer charge when killed.


 * Phase One - stay close to the Nameless One (but not too close) to avoid being blasted by his plasma cannon and attack when the opportunity presents itself. After the Nameless One regains his balance, back off and wait for him to summon a wolf which you can kill to recharge your hammer.
 * Phase Two - the Nameless One will teleport you and him to Earth. He will now summon two wolves at a time, and can launch bombs that bounce a few times before exploding. The Nameless One can also dash at you with his shield - if the shield flashes blue, immediately dash to the side twice to avoid the attack and get out of range of any follow-up slams.
 * Phase Three - this is the same as Phase Two, but whenever the Nameless One summons wolves he will also summon an orange Hell knight; ignore it if possible and focus on the Nameless One (any summoned demons that are hit by the hammer will instantly die, and the knight will probably be within range when you use the hammer on the Nameless One).
 * Phase Four - this phase begins after a short cutscene, ending with the Nameless One teleporting you and him to Ingmore's Sanctum. The Nameless One can now summon a group of four demons, including a mancubus, a pain elemental, a baron of Hell and a tyrant; unless you are in serious danger, continue saving your hammer charges for the Nameless One and depleting his health as quickly as possible.
 * Phase Five - this is the same as Phase Four. Deplete his health as quickly as possible while keeping an eye on your own health and armor.

Trivia

 * In the "Hall of Excellence" in the Advanced Research Complex level of Doom (2016), one of the overhead screens has "All hail the Dark Lord" written on it.
