Doom Slayer

The Doom Slayer, also known by the UAC as DM1-5, Doom Marine or the Slayer; and named by the demons of Hell as Unchained Predator or Hell Walker.

He is an ancient warrior who was banished to Hell or decided to stay there, where he was captured by demonic forces and sealed in a volcanic rock tomb. He was later recovered by the UAC who held him "captive" for study until the infernal hordes invade the base; He then escapes armed only with a pistol and his exoskeleton called the Praetor Suit. He is a legendary warrior, a member of Argent D'Nur's Night Sentinels, whom demons fear for his ability to draw strength from their destruction. It is suggested that he has personally carried out this destruction across multiple dimensions and eons of time. He was found by the Night Sentinels near death, babbling about what he saw in Hell, and was soon trained to become a commander in the Sentinels' war against Hell. His great powers were granted to him by Seraphim Samur Maykr through the use of the Machine of Divinity.

Despite defeating the Icon of Sin and stopping Hell's invasion of Earth, the Doom Slayer's victory over the demons came at a cost. The death of the Khan Maykr and Hell's conquest of Urdak have given the demons the opportunity to dominate all dimensions and restart their invasion of Earth. To prevent this, the Doom Slayer, along with Samuel Hayden and the ARC scientists, embark on a mission to find and free the Slayer's ally, the Seraphim. Traveling by sea on an ARC mobile command ship to the UAC Atlantic Station facility, the Slayer makes his way to the Seraphim's containment pod. When Hayden requests to be loaded into the capsule, it is revealed that he and the Seraphim are one and the same. The second DLC continues directly after the end of the first part, the Slayer shoots the Dark Lord, but he informs him that no blood can be shed in the Luminarium, and that, if the Doom Slayer survives, he will be challenged in a ritual combat in the capital city of Hell, Immora. The Dark Lord leaves and the Slayer is transported to Argent D'Nur, where he fights off the attacking hordes. He lights the Torch of Kings, an act that is strictly forbidden by the Maykrs, and tells the inhabitants of Argent D'Nur and the remaining Sentinel tribes that he seeks a Wraith crystal to power the Divum Gate. He travels on his Dragon to the Spear of the World, where he meets the hologram of Valen, who gives the Slayer his Sentinel Hammer (now blue). The Slayer discovers that the Spear of the World is not a crystal, but a colony ship that houses thousands of Apparitions.

The Doom Slayer or the Doom Marine (Doomguy) is described as being thousands of years old, an ancient warrior entombed in a sarcophagus but not dead, but rather cursed to slumber for eternity unless awakened by some other means. Yet, for an Ancient Warrior, his armour his highly advanced by any standards, and his skill with guns is evident, as the first weapon he sees when waking up after who knows how long is a pistol, and immediately he uses the weapon to great effect without having to learn how to use it or get the hang of it; he's used them before. A record found at the ARC Complex shows that his blood had been tested as AB+. His genome is confirmed to be that of a normal human, but unidentified foreign bodies are also present in his bloodstream, which may explain his superhuman strength, speed, and endurance. This is revealed to be due to the Maykr's technology, to grant him those abilities for reasons that remain uncertain. He stands about 7 feet 0 inches (2.13 m) tall and weighs 500 pounds (227 kg) in armor; without it, he stands 6 feet 8 inches (2.03 m) tall and weighs 360 pounds (163 kg). His armour is dark green with a hint of bronze on his abdomen and some silver all around, His helmet covers his whole face and has a blue visor that covers his face.

He is extremely ruthless; He literally tears apart monsters with his bare hands, casually tearing apart corpses in order to gain access to restricted areas and seeming to relish the destruction of everything that moves around him. He identifies himself and tries to protect humans from the ravages of demons. Despite his sadistic tendencies and antisocial behavior, the Doom Slayer's heroic efforts have nonetheless led to him being hailed as the savior of the human race and the bane of Hell itself. he's also thoughtful, willing to think about the big picture, and he cares about the lives of innocents. The Doom Slayer is in no way patient, but he doesn't kill if it isn't needed and takes care to make sure there isn't an unnecessary loss of life.

Doom Slayer doesnt really have a name so most people jist call him by nicknames. He is incredibly impatient and brutal, always looking for the most violent solution, specially when it comes to demons. He has a lot of confidence in his habilities and knows what he is capable of. He shows a very antisocial nature and never interacts with other human beings, only focusing in protecting them, his thirst for blood and his duty doesnt let him form bonds with anyone. Interestingly, the "Argent" symbol (commonly associated with the Doom Slayer) looks very similar to an angled anchor and the lettered versions appear to say "U N S C" or "U N C S", although this could be purely coincidental, suggesting a possible marine unit insignia.

He has a very muscular and scarred body, his face is very masculine with a defined square jawline, dark eyes, brown hair and a perpetual angry expression.
