Central Timeline

Past

Not too much is known about Doomguy's history before the events of the series. This is because, according to series co-creator John Romero, that little information was given about Doomguy's backstory in order for the player to better place themselves in his role. Id Software has stated their games shared the same continuity, and that Doomguy is the son of Commander Keen, who is the grandson of William "B.J." Blazkowicz, which would effectively make Doomguy "William "B.J." Blazkowicz III". As a nod to this, the spin-off game Doom II RPG introduces a playable character named Stan "Sarge" Blazkowicz who reuses the Doomguy's facial sprite.

What is known is that Doomguy was an enlisted man in the marines. He owned a pet rabbit who he named Daisy and was very fond of. Along with this, it is shown that Doomguy actually had a wife and an unidentified child, as shown in a family photo that can be found in Doom Eternal. Before the start of his demon-slaying career he, and presumably the rest of his team, was sent to serve in Union Aerospace Corporation (UAC) security on Mars as a punishment for punching his superior officer, who ordered Doomguy to fire upon innocent civilians during an unknown conflict. This shows that he will go as far as committing insubordination to protect innocent people.

Doom (1993)

While on Mars, a catastrophic failure occurred when scientists tried to master interdimensional travel so they could open portals between Phobos and Deimos. The failure caused Deimos to disappear, and a portal to Hell to open, causing a hellish invasion. With Doomguy's unit being the only battle-ready unit on Mars, they were sent to Phobos for damage control. Doomguy was left alone to guard the exterior with only a pistol, while his buddies went to confront the situation.

All of his comrades ended up either dead or transformed into Zombiemen. Doomguy went in to confront the demons, grabbing more weapons along the way, like the shotgun and plasma rifle, as well as one of the most iconic weapons in his arsenal: the BFG 9000. After killing the Barons of Hell on Phobos, he attempts to escape the moon by teleporting off of it, however, he is attacked by demons and is outnumbered, causing him to die and be sent to hell on Deimos, which is now inside of hell. He later killed the Cyberdemon, one of the head demons. It was there that he learned that Deimos was now floating above Hell itself. He went into the nightmarish landscape, and slaughtered as many demons as he could, including the leader of the invasion, the Spider Mastermind. After killing it, Doomguy entered a portal and returned to Earth.

When he came back, however, everything was in chaos. The demons used the same portal and used it to invade Earth. killing billions of humans, as well as Doomguy's pet rabbit, Daisy. Doomguy then fights to stop the demons from killing the remaining humans, and he once again kills the Spider Mastermind. This is where he learned that not only did the demons use the same portal he used, but they killed his pet rabbit. Filled with anger, grief, and a thirst for vengeance, Doomguy went out to bring the pain to the demons, that caused him this tragedy.

Doom II: Hell on Earth

Doom IIpicks up right where the original game left off. Ever since they left Hell, the demons have caused destruction, chaos, and mayhem on Earth, killing billions of innocent civilians. The only way for the survivors to evacuate Earth is to head to the last Starport, but it was occupied by the demons. Luckily, Doomguy went there and cleared out the Starport, finishing off demons like Pain Elementals and Revenants, allowing the humans to evacuate the planet. After leaving, the humans helped Doomguy by pinpointing the origin of the invasion: his hometown. He went to the very place that built him into the man he became, slaying all demonic invaders there. He later came back to Hell, killing the Icon of Sin, thus stopping the demonic invasion in its tracks, allowing the remaining humans to come back whenever they are ready to rebuild. He then returns home, victorious.

Doom 64

Mankind has returned to Earth and begun to rebuild, but Doomguy was not feeling peace. After traveling through Hell and back three times and counting, he suffered from nightmares and mental trauma, something the UAC psychologists could not fully treat. After several years, the Doomguy is pulled back into action during his extended vacation. One of the UAC's abandoned research facilities, which had been thought sterilized of demonic presence by use of heavy radiation, is now sending an early warning transmission about another growing demonic invasion. Doomguy suits up, ready to hunt the new source of the demons.

After another long, hard battle with the newly empowered demons, Doomguy stands victorious over the "Mother Demon" and her resurrected army. Doomguy swears that he will remain in Hell for all eternity, ready to do battle and ensure that the demons will never again rise to power and threaten mankind.

Before Doom (2016)

The demons… they are everywhere. Must… kill them all!
~ Doomguy in Doom Eternal.

Doomguy, after many years of battle, ends up going into a different dimension and ending up on the planet Argent D'Nur. There he is captured by the world's inhabitants, the Argenta, and brought before the Order of the Deag in Sentinel Prime. The Argenta were unable to understand his language and he was incoherent, as his mind was crippled with rage and ptsd and he could only think about demons. The Priests decided to put him through a trial by combat in the Blood Arena in order to judge on whether he would gain his freedom. Eventually, Doomguy proved himself to be extraordinarily skilled and earning the admiration of the Argenta. This garnered the attention of the clergy and ruling powers of Argent D'Nur, including the Khan Maykr herself, and he was taken in and trained in their military.

Eventually, Argent D'Nur was invaded by the demons and Doomguy immediately entered the fight; in which his fervor for their destruction soon caught the attention of King Novik, who deemed him worthy to join the Night Sentinels. Doomguy participated in a pivotal battle against the Dreadnought, a monstrous Titan sent to lead a total demonic assault on the heart of Argent D'Nur. As the Sentinels were nearly overwhelmed by the demons, Doomguy was approached by a Maykr, known as the Seraphim, who offered his help to defeat the Dreadnought. The Maykr and the other priests would then perform a ritual on Doomguy which would turn him into the strongest version of himself possible. After this, he would fight alongside the night sentinels for years, slaying countless demons with them. Before long, the demons would grow to fear him and eventually, he would be known as, The Doom Slayer.

Hell sent all their forces after him to end his scourge of hell, but none prevailed. This would even include a titan demon, who he also managed to kill. The Doom Slayer was unstoppable. Having failed to kill the Slayer at every attempt, the demons instead lured him into a Blood Temple before collapsing the entire structure on top of him. Trapped beneath the ruin, the Slayer was entombed within a sarcophagus and frozen in stasis within the Kadingir Sanctum. He would remain there for an extremely long time until he was found and recovered by an Union Aerospace Corporation expedition led by Dr. Samuel Hayden while procuring demon specimens and Hell artifacts. Hayden led his forces in defeating the demons that fiercely guarded the sarcophagus and taking the Slayer to the UAC facility on Mars. Upon identifying the Slayer and his armor from within the Helix Stone, and the developing suspicion of his employee and former protégé Olivia Pierce, Samuel had the sarcophagus hidden in a concealed location within the UAC facility. Upon suspecting Olivia's pact with Hell and her plans for the Mars facility, Samuel intended to release the Doom Slayer in the event of the UAC losing control of its demonic experiments.

Doom (2016)

PraetorSuit

The Slayer is awakened after an unknown amount of time by Samuel Hayden during a demonic invasion of Mars triggered by Olivia Pierce. Upon breaking out of the facility he proceeds to Resource Operations to repair a satellite dish in order to get a complete picture of the situation. Hayden stops the Slayer from accessing the information in question and guides him to a VEGA terminal in order to give the Slayer an argent cell to improve his suit. The Slayer proceeds through the Foundry, stopping a meltdown by activating the terminals and then onto the Argent Tower itself. Despite instructions from Hayden, the Slayer smashes the filters channeling Argent energy to stop Pierce from opening a Hell portal. Despite this, upon reaching the top of the tower and confronting Pierce she uses an Argent Accumulator to break open the rift into Hell and warping the Slayer to Kadingir Sanctum.

He fought his way through the Sanctum to the location where his Sarcophagus was located in order to use the portal equipment left from a manned UAC expedition. Upon returning to Mars, he finds the UAC facility overrun with demons as the demonic portal allows them easy access to the red planet. He finally meets Hayden face to face and Hayden instructs him in finding the Helix Stone to locate the Well and ending the Hell invasion, as well implanting a program into his suit that will allow him to teleport the Slayer back to Mars. The Slayer traveled to the Advanced Research Complex and retrieves the BFG 9000 before proceeding into the heart of the cult activity on Mars. He proceeds to the Lazarus Labs and fights the Cyberdemon before using the accumulator that powered the boss demon to teleport him back into Hell. He then fought his way through the Titan realm and the Necropolis on his way to obtain the Demonic Crucible. After defeating its guardians he retrieved the Crucible and is greeted by ghosts of the Sentinel Knights. Before any exchange can happen, he is teleported back to Mars specifically to VEGA's primary facility. In order to reach The Well and cut off the power source keeping the portal on Mars open he has to overload VEGA's systems to rip open a portal to the Well. Before overloading VEGA's core however, the Slayer pauses and backs up a copy of VEGA onto a thumb drive he takes with him.

Finally, at the Well the Slayer fought his way to each of the Wraith bodies and uses the Crucible to absorb their energy to cut off the flow to the portal. Once the final Wraith has been disabled the Slayer is greeted by several Sentinels who stand guard around a pit leading to the final battle. Here he meets Pierce, bloodied and in shock that she was betrayed by her demonic masters. These same masters then hit her with a crimson lightning bolt, turning her into the Spider Mastermind, though it is ultimately killed by the Slayer. After this Hayden pulls the Slayer back to Mars and keeps him restrained by the teleporter. He takes the Crucible from the Slayer, stating he would use it to continue the production of Argent energy for humanity's benefit. Knowing the Slayer would attempt to stop this plan, Hayden teleports the Slayer away to an unknown location.

Doom Eternal

...and you will be their savior, your strength will be their shield and your will... their sword. You remain... unbroken... for your fight... is eternal.
~ King Novik's ghost to Doomguy.

As a new demonic threat erupts on Earth, so does the Slayer, his iconic Praetor Suit modified and upgraded for increased mobility and destructive capability. For the Slayer, it is a battle that has continued for an eternity, a fight that can only be won by confronting his past if he hopes to stop history from repeating itself.[1]

VEGA has created an inter-dimensional man-machine gateway that allows the Slayer to engage in skirmishes across the multiverse directly. As the Slayer enters the gateway, his surroundings take the form of an arena, in tandem with the arrival of adversaries ready for battle Seemingly extracted from the data of his experiences, the opponents the Slayer faces are familiar but now transformed by some unseen force.

With further analysis Vega observed ephemeral distortions within the fabric of reality; scrambled reflections of the physical world. As the slayer interacts with this anomaly, a peculiar ripple in the anomaly's composition emerges, seemingly reacting to the Slayer's presence reflexively. The anomaly reshapes itself, calibrating itself to the Slayer, responding to his memory, ancestral, and memetic data, before ultimately projecting itself onto the Slayer himself.[2]

Following the events on Mars, the Doom Slayer returned from his banishment with the Fortress of Doom controlled by VEGA and finding Earth invaded by demons. Seeking to end the demonic invasion, the Slayer sought to eliminate the masterminds of the invasion, the Hell Priests Deags Nilox, Ranak, and Grav, while also coming into conflict with the Khan Maykr, who authorized the consumption of Earth in order to harvest the souls of mankind into Argent Energy, following the destruction of the Well.

The Slayer first killed Deag Nilox before confronting Ranak and Grav, displaying their dead colleague's decapitated head before them. The Khan Maykr intervened, teleporting Ranak and Grav away and failing to convince the Slayer to give up in his mission. The Slayer traveled to the Sentinel world of Exultia to retrieve the Celestial Locator that will allow him to find the remaining Hell Priests. There, he encounters the ghost of King Novik, who also tells the Slayer to give up his crusade against Hell and the Maykrs, claiming Earth is no longer his to save. The Slayer then travels to Hell to retrieve a power source for the Celestial Locator from the Betrayer, who also request the Slayer to kill his son that has become the Icon of Sin and gives him a dagger to carry out the deed.

With the Celestial Locator, the Slayer tracked down Ranak in the former UAC Arctic facility, defeating his Doom Hunters, and decapitating the hapless Hell Priest with the Doomblade. His actions caused the Khan Maykr to move Deag Grav to Sentinel Prime. Following VEGA's suggestion, the Slayer embarked on finding Samuel Hayden to find the last Hell Priest. Traveling to the ARC Complex, the Slayer roughly retrieved Hayden's damaged robotic body and recovering the Crucible; in which Hayden had anticipated his return and instructed his ARC caretakers to give the blade to the Slayer. While retrieving Hayden, a corrupted night sentinel, known as a Marauder, approaches and attacks the Slayer only to meet his end shortly after. Upon uploading Hayden's mind into the Fortress of Doom, the Slayer learns from him of Grav's location and that the only access to Sentinel Prime is through a portal in the the city of Hebeth in Mars' core. The Slayer travels to a UAC facility on Phobos where he uses the massive BFG-10000 to blast a hole in Mars, which he uses to reach Hebeth. After arriving in Sentinel Prime, the Slayer fought and killed the Gladiator, and killing Grav by blowing his head up with his Super Shotgun. However, Deag Grav's death on sacred ground cost the Slayer to be excommunicated from the Night Sentinels.

Following the death of the last Hell Priest, the Slayer was temporarily trapped on the Fortress by the Khan Maykr, who remotely shut down the structure to prevent the Slayer from continuing his interference and revealing her intentions to awaken the Icon of Sin. However, the Slayer returned power to the Fortress by using the demonic Crucible as its power source, and later traveling to Argent D'Nur to retrieve his Crucible that he used to slay the Dreadnought and using it to stop the Icon. As the Crucible's blade keeps the Dreadnought from returning to life, the Slayer only took the Crucible's hilt and using it to forge a new blade.

Guided by Hayden, the Slayer fought his way to the roof of Nekravol and using its portal to travel to the Maykr realm of Urdak, where the Khan Maykr prepares to waken the Icon. He interrupts the awakening ceremony and plunging the Betrayer's dagger into the Icon's heart; this destroys the heart and freeing the Icon of Sin from the Maykrs' control and causing the massive demon to destroy the dimensional barrier between Urdak and Hell, thus allowing the demons to break their pact with the Maykrs and directly invading Urdak. The Slayer fought and killed an enraged Khan Maykr before returning to Earth to confront the Icon but is forced to leave VEGA on Urdak in order to open a portal to Earth. Following an intense battle, the Slayer kills the Icon by stabbing the Crucible in its head. With the Icon dead, along with the Hell Priests and the Khan Maykr, demons were momentarily defeated.

Doom 3 Timeline

Doomguy is once again a nameless space marine who holds the rank of Corporal. As it just so happens, he gets shipped to the UAC Mars research facility with Counselor Swann and his bodyguard Jack Campbell on the same day all Hell breaks loose. Within minutes of the invasion, the main military units are zombified by evil souls, and the remaining staff are killed off by the attacking Demons. Only a few scattered squads remain, mainly Bravo Team, with whom the player tries to regroup for a large part of the game.

Doomguy's first mission, assigned to him by Master Sergeant Kelly, aka “Sarge”, is to find a missing scientist named Jonathan Ishii who was last seen at the old communications facility. When found, he babbles about sending out a warning - “The Devil is real! I know. I built his cage.” With those words, Hell erupts from the main experimental gateway, sending a shock wave through the complex, along with glowing pentagrams and scores of evil ghost skulls that transform nearly every human into zombies, including Ishii. Leaving Doomguy the only survivor of the wave.

Later in the game, Doomguy runs into a colleague of Betruger, who says that he became obsessed with the teleporters when he figured out Hell existed on the other side. He says he took an artifact called the Soul Cube from the archaeological digs from the ancient Martian civilization into Hell, and demons followed him out.

Doomguy never meets up with the remaining Marines, save for one in a cutscene that dies shortly afterwards. He only reaches Swann and Campbell on their deathbeds. Swann was badly injured, and Campbell went on to hunt Sarge. Swann says that Kelly has turned evil and is now on Betruger’s side. However, Sarge mortally wounded Campbell and acquired his BFG 9000. After killing Sarge, the player finds an archaeologist, who explains that the Soul Cube must be used to stop the demon invasion.

After entering the Primary Dig Site, Doomguy discovers a section of Hell that has crept into the Martian underground and deep within the bowels of this Hellscape, they encounter the invulnerable Cyberdemon guarding a “Hell Hole” — a portal to Hell. Defeating the Cyberdemon, which is only possible with the charged Soul Cube, the Cube seals the Hell hole and the game ends.

Afterwards, a Marine recon team and sentry drones arrive to secure the base and evacuate Doomguy, however Counselor Swann has already died when they find him. Dr. Betruger is nowhere to be seen and has transformed into the Maledict.

RPG Timeline

Doomguy is a marine employed by the UAC, sent to assist members of the UAC facility on Mars, who are under attack from the denizens of Hell. Doomguy must visit seven "sectors" of the base that have been infested with monsters. Various scientists are encountered along the way, including Dr. Jensen and Dr. Guerard. Examining computer screens and talking with scientists, there are many rumors of a UAC scientist named "Kronos" who was working on teleportation experiments and was fired by the UAC for "security breaches". As the game advances it becomes clear that Kronos is still in the base, and that he is the cause of the attack.

Dr. Guerard begins giving the player instructions. In sector 3, Mr. Nadira lures the player into a trap. The other scientists begin to express their distrust of Guerard and in some Sector 6, it is revealed that Nadira and Guerard are working together. Guerard double-crosses Nadira, allowing a demon to kill him.

A second attack leaves the base in ruins; however, Dr. Kelvin opens the door to the Reactor area. Doomguy confronts Guerard at the entrance to the reactor, who reveals that he is Kronos and transforms into a demon. After defeating Kronos, Doomguy destroys the power couplings of the reactor, closing a portal to Hell (the player is hindered by monsters that come through the portal). After having closed the portal, it is revealed that the Cyberdemon, a combination of demon flesh and human technology created by Kronos, came through the portal at the last second. Doomguy must defeat the Cyberdemon to complete the game.
