The Doom Slayer

Voiced by: Matthew Watterson
"Rip and Tear, until it is done."

"In the first age, in the first battle, when the shadows first lengthened, one stood. Burned by the embers of Armageddon, his soul blistered by the fires of Hell and tainted beyond ascension, he chose the path of perpetual torment. In his ravenous hatred, he found no peace, and with boiling blood, he scoured the Umbral Plains, seeking vengeance against the dark lords who had wronged him. He wore the crown of the Night Sentinels, and those who tasted the bite of his sword named him... the Doom Slayer."

A silent, unnamed Space Marine who awakens laying inside a stone sarcophagus on a UAC base on Mars that has literally gone to Hell. After smashing in a zombie's head with his bare hands and acquiring his Powered Armor from another nearby coffin, the marine proceeds to butcher his way through an army of demons to put an end to the madness.

While his past is initially shrouded in mystery, one thing that is clear is that he's been murdering his way through the legions of Doom for seemingly several eons, to the point that all of Hell now calls him "The Doom Slayer." As the demons were utterly unable to kill him, they instead sealed him away in the sarcophagus, before the UAC discovered him during an expedition into Hell.
  • '90s Anti-Hero: Has many simple, yet gritty names, No Social Skills, a penchant for grievous bodily harm, oftentimes using his own bare hands, a threatening presence to both humans and demons alike, and a simple, yet effective Kill 'Em All strategy to handling demons and their tech using an oversized arsenal. He could just as well have been a villain if not for his solid moral centre underneath the anger and, come Eternal, how it's really hard to disagree with his stance on meddling with the demonic.
  • Action Hero: As with previous versions, the Doom Slayer is a straight-up balls-to-the-walls killing machine who slaughters his way through the forces of Hell without qualm or respite.
  • Adorkable: Yes, really.
    • The Doom Slayer's response to finding a tiny action figure recreation of himself? Give the little dude a fist-bump, wiggling his fingers as he pulls his hand back.

    • When the Slayer finds a similar collectible toy of himself in Eternal, he unsheathes his Blade Below the Shoulder — then raises the figure's left hand in the exact same pose before bouncing it up and down in happiness for a few moments.
    • He keeps an oil painting of him holding a cute, fluffy bunny rabbit in his office. This is one of the first and biggest hints that he's the Doomguy.
    • In both games, he can seek out and collect a variety of cute action figures of both himself and the demons; he even has an entire shelf set aside for them in the Fortress of Doom.
  • The Ageless: As given by what visible features we do see, the Slayer's still very evidently in a physical prime. The Khan Maykr even calls him 'once a mortal', implying that either his exposure to Hell energy or the Argent infusion done by Samur halted his aging. Taken even further in that he's a human being, and thus has stayed in relatively-young adulthood for bare-minimum one hundred and fifty years, and given how the demons describe how he has been around since 'the first age when the shadows first lengthened', that really is a bare minimum.

  • Ambiguously Human: Has the outer appearance of a human, understands how to use human-made computer interfaces and weapons without any explanation, but also has strange runes etched on his hands, and doesn't flinch when exposed to demonic energy that turns most people into zombies. His Praetor Suit, which was supposedly forged in Hell, has the English letters and numbers "8623", "D22", "CAUTION" and "1/0 Logistics Manufacture" printed on it. In Eternal, Novik and the Betrayer also call the people of Earth "your people" while talking with the Slayer. Logs found in Doom Eternal confirm the Doom Slayer is genetically human (further confirmed by him being Doomguy from the original games), but his body is infused with things the UAC cannot identify which give him his increased speed and strength. A Flashback shows this is something done to him by the mysterious hooded "Seraphim", one of Khan's right-hand angels, during his time with the Sentinels. The Khan Maykr notes that he's no longer a mortal, while Hayden refers to him as a Titan much like the Icon of Sin.
  • And Show It to You: He's capable of tearing out hearts as part of his Glory Kills mechanic. The gore nests likewise require him to rip out their beating hearts in order to shut them down.
  • Anthropomorphic Personification: In Doom Eternal, Dr. Elena Richards (UAC scientist trying to figure out what/who the Doom Slayer is) gets a crisis of faith, wondering if the Doom Slayer is an agent of God, or some sort of divinity himself. After seeing footage of him singlehandedly overturning Hellish hordes that Earth's greatest weapons could do nothing about, and noting how he's the only thing the demons truly fear, she comes to the conclusion that he must be this. Once a man, now the literal embodiment of Doom.
  • Anti-Hero: While it's very clear that he has a preference for ripping through demon hordes with psychotic enthusiasm, as well as a penchant for violence little can match, he is still on our side for the right reasons.
  • Are These Wires Important?: The Doom Slayer's preferred method for dealing with Argent Energy equipment is to just start breaking things, despite Hayden's demands that he use utmost care (though this is also less a matter of being clueless as to what he's dealing with and more refusing to accede to Hayden's desire to preserve the Argent energy program against all good judgment).
  • Assassin Outclassin': In Eternal, it’s mentioned that the Doom Hunter, a breed of demon that was specifically created to hunt the Doom Slayer, was rendered extinct, and it’s heavily implied the Slayer himself had a hand in that.
  • Asskicking Equals Authority: The surviving Night Sentinels regard him as their king, due to the fact that the Night Sentinels naturally select the most badass Frontline General in the eternal war against demons as the one most fit to rule.
  • Attack! Attack! Attack!: His entire shtick is focused around exactly two things - sheer speed and killing power. If you're not constantly moving and killing, you're going to die; he has absolutely zero defensive potential other than sheer offence. Properly played, he is the fastest and deadliest thing on the battlefield - but only if you take advantage of his strengths.
    • The only enemy in the franchise that comes close to matching his mobility is the Marauder, who is feared and hated by many players for this exact reason.
    • His damage output is unmatched; even the above-mentioned Marauder can easily turn into chunky kibbles in literal seconds if you combo his gear properly.
    • Once he gets the Crucible, all bets are off; nothing in the game is safe from an instant dismemberment by the massive laser sword.
  • Ax-Crazy: The fact using his bare hands to kill demons is the easiest way to restore his "willpower", despite him having guns and blades that can do the job even faster, makes him come off as psychotically brutal, especially when those kills involve doing things like tearing demons limb from limb, shoving his arms through their chests to rip out their hearts, or crushing their skulls between his palms, just to name a few. Played straight with his backstory, which concretely confirms him to be Doomguy of classic Doom, Doom II, Doom 64: though he stayed behind on the other side of the portal to fend off the forces of Hell at the end of 64, an admirable self-sacrifice, the reality kicked in that would come with fighting for one's life every second of every day, with no reliable nutrition, hydration, sleep, or human contact of any kind. By the time the Night Sentinels found him, he was a battered, gibbering mess that could literally operate on nothing beyond murderous intent and refusal to die. His rambling when found becomes King Novik's commandment to the Slayer when unleashing him: "Rip and tear".
  • Barbarian Hero: A sci-fi version. He's a ridiculously muscular, rage-filled lone warrior of legendary skill and ferocity, who after losing his family/home has been wandering the wastelands of Hell taking bloody vengeance on his demonic enemies. By Eternal he's even lost the sleeves on his battle armour and picked up a magical Cool Sword.
  • The Berserker: A quiet, but no less impressive, version. In spite of the fact that he never speaks, his actions and body language make it clear he is very, very angry. Every aspect of his kit enforces this; if you aren't moving and attacking, you're dying. Taken Up to Eleven when he grabs a Berserk Pack, at which point he can One-Hit Kill anything in the game with a ridiculously over-the-top fatality. Highlights include crushing heads between his hands, ripping out hearts, or literally tearing enemies apart, both vertically and horizontally.
  • BFG: Uses a number of guns that are as big as him, including the Chaingun, Gauss Cannon, Ballista, and of course the BFG 9000.
  • BFS: His Weapon of Choice from Argent D'Nur is the Crucible, a Laser Blade greatsword.
  • Book Dumb: Zig-zagged, and ultimately averted. From the first glance, it's very easy to dismiss him as a violent halfwit who is extremely proficient at killing but clueless when it comes to everything else; however, paying attention to the lore in both games will paint a much deeper picture, giving an explanation to his moments of apparent stupidity or thoughtlessness.
    • He completely ignores Hayden's entreaties to preserve the Argent Energy filters, instead smashing them in like an confused gorilla. He knew well before the UAC ever discovered it just what Argent Energy was, and more importantly, what it could cause if left unchecked. The sequel proves him right on both counts.
    • In the same vein, Hayden's pleas that shutting down Argent Energy would cause an energy crisis fall on deaf ears. The reason Argent D'Nur fell was because it became dependent on the stuff, and the Slayer has seen first-hand that, bad as an energy crisis may be, Hell on Earth is ten times worse. Indeed, going by the staggering casualties listed in Eternal's intro and the hideously-ruined state of Earth, he is again proven right.
    • When told that Hayden's wrecked chassis needs to be carefully removed from stasis, he simply grabs it and hauls it into a portal. Given that Hayden was undoubtedly a high priority target for the demons, the Slayer probably guessed that something would be coming to get him, and understood that taking the time to get him out was far more dangerous a proposition than just grabbing him. Sure enough, the Marauder rolls up to the scene literal moments afterwards.
    • He has an extensive library in the Fortress of Doom, and he was somehow able to get VEGA - a fully sentient AI - up and running again from a presumably-bare bones copy kept on his suit.
    • He never hesitates or has any visible issues dealing with technology at any point; while using computers and other devices he doesn't want to smash, he has no problems whatsoever.
    • He was the champion of the Night Sentinels, and by all accounts, he did an excellent job leading them. If not for the Betrayer stabbing him and his True Companions in the back, they would have won.
  • Blade Below the Shoulder: In Doom Eternal, the Doom Slayer's upgraded suit comes with the Doomblade, a retractable knife underslung to the left forearm, which he can use to stab and slash during his Glory Kills.
  • Blood Knight: He's single-mindedly focused on murdering demons, and if the brutality of the Glory Kills is any indication, he likes fighting. Emphasized in an interview with the 2016 Creative Director.
    Hugo Martin: Most people would avoid the gore nests because they start a fight. The Doom Slayer's looking for a fight.
  • Break the Badass: How he turns up mentally in the hands of the Night Sentinels after an untold amount of time in Hell. Some combat therapy and being given a reason to gradually stabilize himself went a long way to restoring his sanity - only to lose everything all over again. This time he settled into a permanent rage instead of breaking again.
  • Broad Strokes: The "Slayer's Testament" from 2016 implies he was involved in at least a version of the events of Doom, Doom II, and Doom 64, in something the demons refer to as the "first age". Whether it was actually him in those games, or he just had similar adventures, is never made clear though, until Eternal confirms he and Doomguy are one and the same, tying their stories together.
  • Bruiser with a Soft Center:
    • He treats the collectible figurines with care. By the time Eternal rolls around, he even dedicates an entire room within the Fortress of Doom to housing his collection, neatly laid out as well.
    • Lore entries in Eternal indicate that, at the very least, he regards VEGA with a certain amount of respect, dedicating part of his time to improving the program's functionalities. The fact that he thought to save a backup copy of VEGA in 2016 is a hint to his Hidden Depths.
    • As he is the original Doomguy, he had a legitimate, wholehearted fondness for his pet rabbit, Daisy. He even has a framed oil painting of him holding a rabbit in his Fortress of Doom... along with an empty cage containing a rabbit's foot.
  • Canon Character All Along: Eternal explicitly confirms the Doom Slayer is Doomguy from the original games, shown in a Flashback on Sentinel Prime wearing his iconic helmet. It also implies that the events of Doom 3 somehow fit into his back story, as he has a Soul Cube of his own, as well. He keeps his old armour in the Fortress of Doom.
  • Canon Name:
    • As has been slated on multiple occasions in statements made by Id Software since Doom of 2016, Doomguy is a direct descendant of the Blazkowicz bloodline. Now, whether or not that means it's the same as in the Doom RPG titles, William Joseph "BJ" Blazkowicz III, hasn't been stated assuredly, but the family name at least is concrete.
    • While it's from an Easter Egg that doubles as a Call-Back, considering all the strides taken to meld every Doom entry as part of the same universe, FLYNNTAGGART being the password to unlock Doom II in-game suggests that the Doom Slayer might use the name he has in the novels, Flynn Taggart, as an alias.
    • Lore entries give his Super Shotgun canonical nicknames by the forces of Hell, akin to dubbing the protagonist the Doom Slayer, Lucifer's Bane, and the Diabolical Musket.
    • With confirmation from DOOM: Eternal that he's related to Commander Keen and that he's the Doomguy from the original series, it's safe to assume that his name is either William Joseph "BJ" Blazkowicz III or Stan Blazkowicz.
  • The Comically Serious: He's silent, incredibly angry and is unbelievably violent. But there is some humour from those aspects of him and what he does, from collecting Doom Guy Dolls, fist-bumping one and in Eternal clearly having no care for personal space. Driven Up to Eleven if the player is having him wear the Doomicorn armour, where he still looks permanently pissed-off and strikes powerful poses, but the goofy white-and-pink armour makes him all but unable to be taken seriously.
  • Covered in Scars: What little is seen of him without his armour is covered with lots of small scars.
  • Cutting the Knot: If he can't solve a problem by shooting it, he'll solve it by punching it. Whatever the most direct means of accomplishing his objective is, he does it without hesitation.
    • Played for Laughs in 2016 when Hayden attempts to verbally guide him through shutting down the Argent Filters without destroying them; Doomguy ignores him and promptly smashes it like an angry gorilla.
    • This trope is taken to its' logical extreme near the climax of Eternal. Problem? He needs to get to a city buried deep under Mars' surface, and there's no way to get there. Solution? Hijack the BFG 10,000 and literally blow a hole directly to it.
  • Death Glare: His default expression is just a piercing glare at whatever pisses him off. He amps it up on several people who have earned a higher spot on his shit-list, and in response to anyone trying to convince him to give up on his quest.
  • Deity of Human Origin: Demigod, for lack of better classification, at any rate. He was an entirely mortal being at first, and human to boot, but that all was tossed to the wayside when Samur, the Seraphim of Urdak, used the chamber meant to purge impurities to infuse Doomguy with Maykr genetics, the Maykrs themselves being the angel race of the Doom reality. As a result, he no longer ages, his physical ability is well beyond normal capability, the Kahn Maykr outright states that he's no longer mortal either, but an examination of a blood sample recovered from him on Mars does confirm that, for the most part, he is by and large a part of the human race.
  • Demon Slaying: What gave it away? Everything the Doom Slayer does has the purpose of putting demons 6 feet under, getting to points where there are demons to be slain, finding new equipment to help him slay demons, or obtaining information and access needed to get deeper into demon territory. He lives and breathes solely for the purpose of slaying demons, and chose to be Barred from the Afterlife to continue slaying them. He will use whatever tools he can find to aid him in the goal of slaying demons, whether they are Improvised weaponry, swords, chainsaws, Laser Blades, or BFGs, it does not matter, and if he runs out of ammunition, he will rip the demons apart with his bare hands, fueling his rampage through their own argent energies, making him a Perpetual-Motion Monster. Demon Slaying is not a profession to him - it is all he is; after being woken up from being a Sealed Badass in a Can, he breaks free of his restraints and bashes the first Demon's head in within five seconds and doesn't slow down from there.
  • Destructive Saviour: Much to Samuel's annoyance, his method for solving problems usually amounts to destroying whatever is standing in his way — including an Argent Energy extractor which took Samuel years to create. In Eternal he shoots a hole in Mars because he needs to get to its core fast.
  • Determinator:
    • His enemies hate and fear this aspect of his personality; see below. Throughout all the countless ages he's been fighting the demonic hordes, he has never once given up nor stopped fighting, even after being trapped alone in Hell for eons on end, losing all of his allies, knowing his actions may potentially doom civilization to a massive energy crisis, or even just being chained up completely naked to a slab with a zombie coming to bite off his face.
      Slayer's Testament: Unbreakable. Incorruptible. Unyielding. .... They knew he would come, as he always had, as he always will, to feast on the blood of the wicked.
    • id Software Creative Director, Hugo Martin, has admitted that Robocop and The Terminator were two inspirations for how the Doom Slayer should behave. Both characters are uncompromising killing machines who never back down, are nearly impossible to kill, and will do anything to accomplish their mission.
  • Did You Just Punch Out Cthulhu?: He's taken out demon lords as big as mountains, killed near-indestructible monsters, and faced down generations of the legions of Hell with little more than guns, blades and in many cases his bare hands. Come Eternal, he's added an alien god and her questionably-angelic minions to that bodycount.
  • Doomed Hometown: After his allies, the Night Sentinels, were defeated and their realm Argent D'nur was destroyed, he embarked on an endless war into the bowels of Hell. With the reveal in Eternal that he's the classic Doomguy, this also means demons invaded his Earth back in Doom II: Hell on Earth, driving him to eventually remain in Hell to forever battle the forces of Doom at the end of 64.
  • Double Jump: His thruster boots upgrade lets him jump an additional time in the air.
  • The Dreaded:
    • The entirety of Hell tried to keep him sealed away during their invasion of Mars for as long as possible, and they only managed to stop him the first time by dropping an entire temple right on top of him. When the UAC found his tomb, the demons began to freak out, fighting with "a desperate ferocity" that the UAC had never seen before. There's a reason he's generally referred to as the Doom Slayer (also Hell Walker, the Unchained Predator, Scourge of Hell).
    • In Eternal, the reaction of the UAC personnel who see him is to recoil in terror. One poor man who has the misfortune of possessing the key the Slayer needs can only lean back in his chair, petrified in fear, and doesn't move as the Slayer grabs the keycard, drags him by the strap to the door lock, and uses it to move on. In the next room, two UAC guards start to challenge the Slayer but go completely silent as they realize who they're talking to, with the Slayer giving the mouthiest guard a Death Glare and taking the terrified man's weapon without a word. The base computer also has alarms specifically to warn of the Doom Slayer.
      Facility Voice: Warning: The Slayer has entered the facility.
      Facility Voice: WARNING: Slayer threat level at maximum.
  • Empowered Badass Normal: The Doom Slayer collects assorted scientific and magical tokens to power himself up; argent energy cells to enhance his armour's basic capabilities, special Praetor enhancement tokens to upgrade various utility functions and equipment traits, and demonic runes to magically augment his capabilities; he's also been empowered by angels with enough strength and speed to go One-Man Army on Hell, though records indicate that he was already kicking huge amounts of ass by the time they did.
    • This extends to his backstory in Doom Eternal; He started out as a Badass Normal when the Sentinels found him, badly wounded after fighting demons since the original Doom games for god knows how long; and even when he was battered, wounded, and weak he still handed the asses of everyone they threw at him in the Colliseum, and after being given the "prize" of being Cannon Fodder on the frontlines with the other "Arena Champions", he continued to fight and live when everyone else in his "rank" died. When the Demons invaded and all hope looked lost, one of Khan Maykr's right hand angels, The Seraphim, put Doomguy in a machine that was supposed to weed out the darkness out of the Sentinels. The Seraphim instead used it to power Doomguy up into the Doom Slayer by pumping him full of Pure-Maykr Grade energy.
  • Elective Mute: Doom Eternal notes that he’s fully capable of speech, but stopped doing so after gaining his enhanced power. He’s been completely silent for millennia.
  • Establishing Character Moment:
    • The intro of the DOOM (2016) is one for the Slayer: He wakes up naked and chained to a slab, after Hell's forces sealed him in a coffin and dropped an entire temple on top of him just to be safe. The instant he's awake and aware, he rips out the chains, smashes a zombie's head to paste with his bare hands, and blasts two others to pieces with a pistol. He then finds his armor and immediately searches for the source of the demonic infection on Mars. After which he goes on to clear another room full of demons. And the moment that Samuel Hayden tries to justify what's happened to the base by saying that his actions were for "the betterment of all mankind", the Doom Slayer looks down on a human corpse, gets enraged by it and destroys the monitor Hayden's speaking on. This establishes the Slayer as a ruthless Badass No-Nonsense Nemesis (to the Demons) who still retains some of his humanity.
    • The Slayer seems to understand and respect authority. He could have done a lot more to King Novik and the Betrayer, who had both separately called him out on his unyielding crusade against the demons, at the possible expense of everyone else, beyond giving a mere Death Glare in response. In addition, when he beheaded Deag Nilox at the start of the game, the Slayer adjusted the Hell Priest's crown, which became lopsided during the event, possibly out of respect for who he once was, and all the help had given the Slayer when he was still Doomguy. Likewise, upon spilling Deag Grav's blood on the arena floor of Sentinel Prime — an act that costs the Slayer his sovereignty amongst the Sentinels — and being faced with a squad of them, he chooses to simply turn away and leave rather than wipe the floor with them.
    • At the start of one of the later levels in Eternal, the Slayer walks through a control room on Phobos filled with UAC employees. Everyone is spooked by his appearance, either looking on in shock or scrambling to get out of his way. One UAC employee has a keycard — that the Slayer needs to access the inner parts of the facility — on a lanyard hung around his neck; the Slayer takes the card (while it is still hung around the employee's neck) and uses it on the nearby control panel to open the door, dragging the poor fellow along by his neck in the process. In the next room, the Slayer stares down a UAC Marine — who briefly admonished him for entering a restricted area before falling silent upon realising who he actually is — before taking said Marine's plasma gun for his own use. Beyond mild discomfort, the Slayer clearly went out of his way to make sure he did not hurt any of the humans who saw him.
  • Eternal Hero: He might have originally been just a man, but the Slayer has become the eternal bane of Hell itself, having torn his way through the demonic hordes for untold eons.
    • Emphasized by King Novik's closing monologue at the end of 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.
  • Evil Is Not a Toy: He is instantly disgusted and angry with the UAC for attempting to harness Hell to answer the energy crisis. The moment he gets his bearings and learns this, he already knows what went wrong, how it will escalate and the danger all of humanity now finds itself in. His attitude and actions show pretty clearly that he believes the UAC recklessly meddled in matters beyond their understanding or control. The consequences don't disprove this outlook, nor does the reveal of just where Argent Energy actually comes from in Eternal.
    • This becomes even more poignant when it's revealed in Eternal that Argent D'nur collapsed because its people and the Maykrs grew addicted to Argent energy and made an alliance with Hell, betraying the Night Sentinels in the process. The Slayer knows exactly what the corrupting influence of Hell and Argent energy is capable of and doesn't want to see it repeated on Earth.
  • Expansion Pack Past: 2016 explained the Doom Slayer was the last surviving Night Sentinel who spent an unknown period of time rampaging through Hell in retribution for the fall of Argent D'Nur. Eternal then expanded his backstory by not only revealing the details of Argent D'Nur's fall and how it relates to him, but also that he was originally the Doomguy from the original games. He entered Hell in Doom 64 to battle the demons eternally only to emerge in the distant past on Argent D'Nur in an Alternate Timeline.
  • The Extremist Was Right: While Samuel Hayden only wants to temporarily shut down the production of Argent Energy, to avoid plunging Earth and its colonies into an energy crisis, the Slayer's respose to this proposal is to destroy the production of Argent altogether, by destroying the filters that alter the raw Hell Energy into Argent. Considering how easily the presence of Hell in any capacity can corrupt mortals, as the UAC clearly demonstrated, and considering the damage the Demons are able to do in such a short time if allowed, it's really, really hard to disagree with him on this one. The sequel lays the argument to rest once and for all by revealing the true nature of Argent Energy, which even Hayden cannot tolerate.
  • Face Death with Dignity: Played for Laughs - his response to burning alive in lava is to give the thumbs up before sinking fully into molten slag.
  • Featureless Protagonist: You never get a good idea of what his face looks like. However, you can kind of see his facial features through the helmet's visor, and he does have a face texture, which some fans were able to rip. In-engine cutscenes that leave the Doom Slayer's perspective shows that his visor is more transparent, with his eyes becoming more prominent. In DOOM Eternal, his face is far more visible, most notably when it's reflected in his visor after obtaining a power-up. In one cutscene, he is also shown without his helmet, at least from behind. Averted come Eternal, both because we see his face at several points, and because we've known what it looked like since 1993.
  • Finishing Move: The Doom Slayer can do these to demons, something borrowed from the popular Brutal Doom Game Mod. It's actually encouraged to do this, as enemies finished off with a "Glory Kill" are guaranteed to drop health pickups (and armour fragments, with a rune), and Glory Kills are the only way to finish off bosses.
  • Fragile Speedster: With his Double Jump and Videogame Dashing, the Slayer is capable of zipping effortlessly around the map and dodging fireballs left and right. And not without good reason, since he can't tank very well at all despite his impressive damage output.
  • From Nobody to Nightmare: Twice. He went from being a faceless UAC marine who was Reassigned To Antartica for refusing to fire on innocent civilians to one of the most relentless killing machines in gaming. His enemies - themselves being monstrosities who make the bogeyman cry for mommy - are absolutely terrified of him. This also applies to his time in Argent D'Nur, where he rose from a nameless slave-soldier to become king of the Night Sentinels.
  • Genius Bruiser: In addition to his enormous build, he's also well-read, an avid gunsmith, a capable leader of armies, and able to perform maintenance on an AI.
  • Glass Cannon: Comparatively at the very least. For all his demon-mauling bravado, and despite his ability to rip apart even the biggest demons around, the Slayer can't take hits from those same demons very well. Virtually every hit from anything larger than an imp will take out a noticeable chunk of health, and the key to his survival thus lies in using his enhanced agility to bob and weave around them to avoid attacks, and his ability to recouperate strength from Glory Kills. The thing that makes it a Zig Zagged Trope is the fact that the Doom Slayer is at least capable of surviving a few hits, even from titans, where a normal human would just be reduced to paste, and judging by the Scarred Equipment that is his armor, he does get hit a lot. The codex entry on the Praetor suit even specifically mentions that it's essentially immune to conventional weaponry; it's just that the demons are using anything but.
  • Godzilla Threshold: Is the proverbial Godzilla for Samuel Hayden, as waking him from his can leads him to destroying everything related or even concerning Hell, including the extremely powerful Argent energy that the company had been exploiting Hell for.
  • Good Colors, Evil Colors: His armour is a mix of earthy greens, greys and browns, compared to the demons' predominately red and yellow bodies that evoke fire and blood.
  • Good Is Not Nice: Clearly on humanity's side, but due to a combination of dealing with people who screwed things up and being too deep into everlasting fury to care, the Doom Slayer is rude as hell. He refuses to listen to people, his only forms of communication are Death Glares and violence, and if you have something he wants, he'll just take it without asking.
  • Grappling-Hook Pistol: In Eternal, the Doom Slayer's Super Shotgun is now equipped with an underslung grapnel attachment that he can use to snag onto enemies from a distance and pull himself closer to them. It's called "The Meat Hook".
  • Grievous Harm with a Body: Some of the Glory Kills he can perform on his unfortunate enemies involve killing them with their own limbs or other body parts.
  • Guest Fighter: The Doom Slayer makes a playable appearance in Quake Champions, with alternative textures allowing you to make him look like his classic incarnation, his design from Quake III: Arena or the Marine from Doom 3.
  • Gun Nut: As Hayden notes, his enthusiasm for firepower is very evident. It's best communicated in Eternal, where when he finally arrives at the helm of the BFG-10K only for the built-in protocols to kick in.
    VEGA: Would you like me to disable the safety protocols?
  • He Who Fights Monsters: Defied - given he's running around in a suit of armour that feeds on Argent Energy, the same Hellish power that the UAC used to create its Possessed and Revenants, it is easy to think that the Doom Slayer is some kind of demonic entity himself. This is all jossed by a research log in Eternal stating in no uncertain terms that there is no way the Doom Slayer is a demon - his blood type is AB positive, and his genome confirms that he is human.
  • Heroes Prefer Swords: His Weapon of Choice from Argent D'Nur, the Crucible, is a massive Laser Blade greatsword.
  • Heroic Build: Eons spent ripping and tearing through the forces of Hell has left him seriously ripped.
  • Heroic Comedic Sociopath: The majority of his violent or thoughtless actions are played for laughs rather than any kind of drama: He murders demons in various ridiculous and inventive ways, usually just goes for "smash it in with your hands and feet" when dealing with UAC equipment, drags around technicians by the keycards attached to their necks or just slings their half eaten corpse over his back if they're already dead, and gleefully steals weapons from random corpses and even living guards.
  • Heroic Mime: As usual, he never speaks - his actions tend to speak louder than words, though. However, pained grunts upon taking damage can be heard from in Eternal. Played with when Flashbacks show him fully capable of talking, with a codex entry stating that he simply chose to stop speaking, so in reality, he simply refuses to speak, given how dead focused he is on his work.
  • Heroic Second Wind: His extra lives mechanic in Eternal is described In-Universe as such - even after nearly being killed by a pack of demons, the Doom Slayer's forcing himself back up with pure anger and willpower to keep fighting.
  • Hidden Depths: Especially considering he never says a word.
    • While he's still a rampaging berserker, he shows surprising depths at times. For instance, he's obviously disgusted with Hayden's callousness toward the loss of life he's ultimately caused, yet still doesn't make any attempt on the man's life when they meet in person (though you can try to shoot him, Hayden has a Plot Armor energy shield). He also hesitates to destroy VEGA, a fully sentient A.I., even though he knows it's necessary, and even ultimately makes a backup first.
    • When tasked with taking out the Argent energy filters, he stomps them with his boot not out of ignorance or a lack of grace, but deliberately because of Hayden's insistence that they are to be treated with care - as destroying them will seal off any Argent energy supply for good - which is exactly what he wants. There will be consequences, yes, but for now stopping humanity's meddling with Argent energy takes priority or there won't be any humanity left.
    • He's also surprisingly adept with technology (when he's not intentionally destroying it), given how long he may have been fighting in Hell. He only ever hesitates on his options for VEGA, and otherwise seems to speed through numerous options and activation with no real difficulty. Even on Olivia's personal and top-secret computers, he doesn't waste a second on any single option each as he picks through them to unlock what he needs. The interfaces may be user-friendly, but he clearly knows what he's doing.
    • Albeit Played for Laughs and more likely considered as Easter Eggs, his Fortress of Doom in Eternal contains many trinkets that would be considered odd for a person with a single-minded dedication to demonic genocide, such as a bookshelf filled with literature on various topics ranging from Earth history to A.I. systems maintenance, several wall-mounted electric guitars (including one made out of argent energy), his massive action figure collection, a tri-monitor desktop gaming system with subwoofers which also serves as his command console, an old IBM 486 computernote , a skateboardnote and perhaps most tellingly, an empty rabbit cage with a single foot inside of it. Who knew the Slayer was a musician, avid gamer, and bookworm?!
  • Hope Bringer: Come the events of Eternal, the Doom Slayer is a figure Shrouded in Myth to most of humanity, though his reputation and the tales of his exploits on Mars preceded him. The ARC and those living under its protection come to see him as a savior and protector, even if his violent tendencies do give them cause for concern. Regardless, his new conquests on Earth gradually emboldens the resistance and inspires hope into them, as they watch him wreaking havoc from afar. He also became one to the people of Argenta as conscripts saw one of their own not only becoming a Sentinel but one of the best when it comes to kill demons.
  • Horrifying the Horror: Really driven home, where various data pads (on Mars) and artifacts (in Hell) make it clear just how terrible the Doom Slayer is for the denizens of Hell. It was said that the demons fought with unprecedented ferocity to prevent the UAC from retrieving the Doom Slayer's sarcophagus.
    Trailer: The only thing they fear... is you.
  • Human Alien: Subverted as Eternal reveals that he's none other than the Doomguy from the original games, having been found and taken in by the Night Sentinels after spending an unknown amount of time in Hell following the events of 64.
  • Human Cannonball: In Eternal, he loads himself into a futuristic cannon, in place of the spherical bomb that it'd normally fire, to launch himself through space and into an infested battle cruiser. It has to be seen to be believed.
  • Humanoid Abomination: The Doom Slayer begins the 2016 game with strange runes etched on his hands, and he doesn't flinch when exposed to demonic energy for the sake of a buff. Eternal further reveals he is in fact 100% human, with a blood type of AB positive and a perfectly normal genome... which makes his superhuman abilities and the unknown foreign bodies seemingly filling his body all the more inexplicable.
  • Hyperspace Arsenal: The Doom Slayer can carry up to nine guns at once, ranging from the humble combat shotgun to the all-obliterating BFG-9000, as well as his trusty chainsaw, a variety of grenades, and the almighty Crucible sword. And that's not even mentioning the wide variety of weapon mods which he pulls out of nowhere to swap around at a moment's notice, ranging from a sticky bomb launcher for the combat shotgun to an mobile turret and energy shield attachment for the chaingun. As such, though he appears to be carrying no more than his armour, a single weapon, his equipment launcher, and a Blade Below the Shoulder, the Doom Slayer has a tool for virtually every type of demonic dilemma Hell throws at him within reach, and he is quick on the draw. At one point in 2016, he even stuffs an entire upper torso of a mangled corpse into his inventory to bypass a retinal scanner.
  • I Have Many Names: He's acquired quite a few monikers from demons and humans alike, including the Doom Slayer, the DOOM Marine, DM1-5, the Hell Walker, the Unchained Predator, the Scourge of Hell, the Great Slayer, and, of course, Doomguy.
  • I Like Those Odds: Though it's a nonverbal version, it's very clear that the Doom Slayer does not care about being outnumbered. His response to being told that he is Just One Man against millions, if not billions, of demons from The Legions of Hell, is to pump his shotgun with a determination that nonverbally screams "I call that a countdown" - and then get right into the thick of it.
  • Implacable Man: The Slayer cannot be reasoned or bargained with. He could at best be mildly slowed down and inconvenienced, by pitting him against innumerable hordes of demons, and he'd still be coming for your skin eventually.
  • Incorruptible Pure Pureness: A very dark version - he's not corrupted by the influence of Hell, which turns most people into demon worshipers or monsters, because there's nothing left in him but pure vengeance.
    Slayer's Testament: Tempered by the fires of Hell, his iron will remained steadfast through the passage that preys upon the weak. For he alone was the Hell Walker, the Unchained Predator, who sought retribution in all quarters, dark and light, fire and ice, in the beginning and the end.
  • Inexplicably Awesome:
    • His ability to absorb strength from demons is never explained - he had it even before the Seraphim bestowed him Super Strength and Super Speed. It's not something the Night Sentinels have either; they all had a Dying Moment of Awesome each, so it's not related to them. However, given that he had been absorbing trapped souls in the form of the Sphere powerups to strengthen himself as seen in the previous games, he might have simply figured out how to do so during his lengthy stay in Hell.
    • His Hyperspace Arsenal is never explained. How does it work? Who made it? Does it have a limit? The answer to all these has so far been a resounding "Who cares, just kill stuff with its contents".
  • It's Personal: Even without the vendetta when he was just known as Doomguy, the demons still corrupted and slaughtered his comrades in the demon killing order of warriors, the Night Sentinels, and then destroyed his homeworld.
  • Jerkass Has a Point: Comes off as a more clear-cut Well-Intentioned Extremist than Hayden, as he knows from experience how much damage can be done if Hell is allowed to corrupt a society. His point gets even stronger when you learn just how Argent Energy is made.
  • Jerkass to One: Right off the bat in DOOM (2016), he seems to develop an instant and almost unreasonable hatred for Samuel Hayden the second he hears that Hayden is the head of the facility. Almost every time he has to deal with Hayden, the Slayer will either violently cut off his transmissions, or deliberately smash the expensive stuff he's explicitly told to keep intact, as if to rub it into Hayden's face. On the other hand, once he figures out just what the UAC is up to, it makes total sense that he'd want to shut their operation down, since he already knows exactly what Argent Energy is and how it's made, and Hayden makes it very clear that shutting it down is not in the cards for him. Eternal shows that he's still more than a little contemptuous at Hayden; when recovering the doctor's shattered chassis, rather than carefully detaching it like the ARC scientist advises him to, the Slayer just nonchalantly yanks him out of his life support systems instead, which makes his entire chassis fall and slam resoundingly against the floor. As if that's not enough, as soon as the Marauder rocks up to the scene, the Slayer just casually flings what's left of Hayden into a portal without even looking.
  • Jerk with a Heart of Gold:
    • Being a person of unstoppable rage doesn’t exactly give you good social skills. Through the games he has proven himself to be violent, gruff, disrespectful, and all around not a nice man to be around. However he is predominately dealing with people who believed they could harness Hell as a power source without consequence. That said, he still cares greatly for the human lives lost, and he’s trying his best to ensure humanity’s survival.
    • As he was about to destroy VEGA's central core, he immediately creates a backup copy on his person before VEGA dies out. He knew full well VEGA would be Killed Off for Real, but his last-second conscious allowed VEGA to stay alive.
  • Knight In Sour Armor: One interpretation of his behavior; he may not be the most calm or peaceful person around, but he still fights for what he believes in and against Hell. His unbridled rage at the UAC shows a cynical and bitter side, and yet his team up with Hayden also shows he'll put it aside on a whim for the greater good of stopping Hell again.
  • Lantern Jaw of Justice: At the start of Eternal, the audience is given several good glimpses at his massive chin and squared, heroic jawline.
  • Late-Arrival Spoiler: A good two years prior to Eternal, his true identity as the Doomguy was first laid out explicitly in his Quake Champions bio. However, this seems to be a case of Canon Welding, as Quake Champions wasn't considered to be fully canon when it comes to the bios of its Guest Fighters.
  • Legendary in the Sequel: He's The Dreaded to the forces of Hell and demanding their full attention to stop him from halting their invasion. Goes further since he's the original Doomguy, who was just one among the many marines in the older games.
  • Lightning Bruiser: He's capable of outrunning virtually every demon and delivering punishing firepower while tearing them apart with his bare hands, but in return, he needs to stay on the move constantly in order to survive, to the point the developers have stated "if you stand still, you're going to die".
  • Living Legend: He's basically become to the Demons what they are to us, being feared in-story and having all the forces of Hell either wary at least or outright shitting themselves at the very worst.
  • Megaton Punch: In Eternal, he gains the "Blood Punch" ability, which allows him to deliver a supercharged punch that reduces anything standing in front of him that's weaker than a Hell Knight into red slop on the floor.
  • Mook Horror Show: The Slayer's Testament, an account of the Doom Slayer's endless rampage against Hell, reads like a demon bedtime horror story. An unstoppable foe carving a bloody path through their forces with the wrath of the heavens itself. That is until confronted by Hell's mightiest champion, the colossal Titan. But even the Titan falls to the Slayer's might. The Testament's finale, when the demons seal their nemesis away because he could not be killed, still carries the implicit threat that one day: he might escape.
  • Multi-Melee Master: Adept with a wide range of close-combat techniques and weapons, including his hands, feet, Pistol-Whipping, a forearm mounted blade, chainsaws, a giant laser greatsword, and even random dismembered demon body parts.
  • Multi-Ranged Master: General rule of thumb: If it can be used to kill, the Doom Slayer knows how to kill with it after a few seconds of inspection. He has used rocket launchers, miniguns, turrets, shotguns, pistols, plasma rifles, railguns, grenades, assault rifles, Swiss Army Weapons, BFGs... the list goes on.
  • Multiple-Choice Past: In 2016, codex entries give few concrete facts about the Doom Slayer's origins, but plenty of Wild Mass Guessing fuel. Several references to the classic series enforce the fan theory that he's the Doomguy. However, there's also hints that the Doom Slayer was the last surviving member of the Night Sentinels, protecting the dimension that Hell completely subsumed. Eternal confirms both are true - he is Doomguy and the Sole Survivor of the Night Sentinels.
  • Names to Run Away from Really Fast: The demons, who call their forces "the slaves of Doom", have a name for him, too - the Doom Slayer.
  • Never Hurt an Innocent: Doom Slayer despises demons, Hell, and anyone collaborating with either. He'll kill anyone that's been corrupted and turned like the Hell Priests or the Marauders. However, he's trying to save the earth as well and not just kill the demons after all, if he was only concerned with killing the demons he wouldn't go out of his way to stop the Maykrs from sacrificing the earth. He's trying to save humanity while also waging war against Hell and any time he interacts with normal people, he may be rude and scare the shit out of them but he won't hurt them.
  • No-Nonsense Nemesis: A rare example where the protagonist is the nemesis. The Doom Slayer does not waste any time when it comes to dealing with his enemies; he dispatches them as ruthlessly and efficiently as possible. None of the Priests survive more than thirty seconds once he closes to quarters with them.
  • No Sense of Personal Space: In Eternal, rather than asking for UAC employees to hand over a keycard or a plasma rifle, the Doom Slayer drags the terrified worker over to the card input with it still around his neck, and just snatches the rifle out of a soldier's hands.
  • Nonstandard Character Design: Despite the Slayer's Testament claiming "he wore the crown of the Night Sentinels", his armour looks utterly different from any other Night Sentinel you meet, even in scrolls depicting him fighting side by side with them. While they look closer to sci-fi versions of medieval knights in white armour, the Doom Slayer's suit looks closer to an Earth designed one reforged with Hell touches, and it's colored with nothing but greens, browns and greys instead.
  • Offscreen Moment of Awesome: During his rampage of Hell, he fought a massive demon called the Titan, Hell's greatest champion, and now its massive skeleton litters the aptly named Titan's Realm region of Hell.
  • Older Than They Look: Despite having the appearance of a man in the prime of his life, the Slayer's Testament claims "The age of his reckoning was uncounted" and "The scribes carved his name deep in the tablets of Hell across eons." Even if we assume he's from the current Earth's timeline originally, given Doom takes place in 2022 whereas 2016 is set in the year 2149, at absolute minimum, he's over 150 years old.
  • Omnicidal Maniac: Downplayed - his adopted policy for demons is murdering them all, violently. If you're not that you're fine. If you are, then you won't be alive much longer once he catches up to you.
    Samuel Hayden: You see, I've watched you work - come to understand your motivation. You think the only way is to kill them all - leave nothing behind - and you may be right.
  • One-Hit Kill: The Crucible blade in Eternal will one-shot any non-boss demon it hits. Even the likes of the Tyrant or Marauder will instantly fall to it (albeit impractical to perform in the latter case). The only exceptions to this rule are the Doom Hunters, which require two, one for each of their phases. The downside is that it only stores 3 charges at once, and charges are hard to come by.
  • One-Man Army: Oh boy. This guy is possibly this trope distilled. For starters, he singlehandedly crushes the Mars invasion in a matter of hours almost entirely on his own, killing absolutely everything sent his way with extreme prejudice, including several of Hells strongest demons. This is pretty much taken Up to Eleven in Eternal, as he's pretty much the sole effective soldier in the fight against a planetwide invasion from Hell. No less than five of the Video Game quotes on the trope page pertain to him, and he's earned them all.
  • Only Sane Man: It's quite clear he does not buy a single syllable of the shaky self-satisfied Well-Intentioned Extremist malarkey the UAC keeps feeding him, because said malarkey is also what keeps on provoking demonic invasions. To him, there's exactly three things in the world: Kill demons, save the world, and do it as efficiently as possible.
  • The Paladin: He's the most exalted warrior of the Night Sentinels who are basically paladins but in another dimension. While he's a rather macabre take on this trope, he most certainly fits the general bill, what with his hatred for demons and his mission to repel the literal Legions of the Damned, in order to protect innocents from eternal damnation.
  • Pay Evil unto Evil: The Slayer inflicts brutality and pain on the denizens of Hell on such a destructive scale that even they are horrified at his actions. His enemy knows no mercy or pity, so he offers them neither.
  • Perpetual Frowner: Though he has a Face Framed in Shadow and Hidden Eyes to emphasize ambiguity and a potential Audience Surrogate, what little can be seen of his face (especially once fans extracted it from the model) is a perpetual frowning grimace of sorts. It works surprisingly well with his Knight In Sour Armor status and disgust for the forces of Hell.
  • Perpetual-Motion Monster: From the view of the demons at least - according to the Slayer's Testament, he has the ability to absorb the strength of the demons he slays, meaning he does not need to sleep, eat, or drink as long as he keeps on killing. His rampage has lasted ceaselessly throughout the eons, and it was only momentarily paused by collapsing a temple upon him and making him a Sealed Badass in a Can - once he escaped that, he got right back to killing demons without even a pissbreak.
  • Person of Mass Destruction: The UAC's final failsafe in the case of a demonic invasion is not to nuke their facility, but to let the Doom Slayer out of his coffin.
  • Pet the Dog:
    • When Samuel Hayden tries to justify his actions in creating the mess over the intercom, the Doom Marine's response is to look down at the corpse of one of the victims, crack his knuckles, and smash the intercom in disgust.
    • When it becomes necessary to sacrifice VEGA, the Doom Slayer hesitates for a moment and makes a back-up of the AI (which he then keeps with him) before pushing the button.
  • Physical God: Played with - he's strong enough to rip apart demons that can shrug off rockets and ballistic slugs with his hands, can launch himself out of a railgun through the vacuum of space followed by the walls of a heavily armoured battle cruiser without any visible injury, and somehow even killed a Titan of Hell, whose corpse forms the environment, before he gets the Praetor Suit.
  • The Power of Hate: With a bit of Gameplay and Story Integration, the extra lives system in Eternal are Justified by his hatred for Hell being so great that, even if killed, he wills himself to live again out of sheer psychopathic hatred for the demons. Likewise, the health pickups are Justified by his willpower being restored with every demon he kills.
  • Powered Armor: His Praetor Suit, which was built/enhanced by a rogue demon to feed off Argent energy itself. On a more mundane level, it keeps track of his current vitals, provides a Heads-Up Display that feeds various info to the Doom Slayer, has a Comm Link system, and can integrate with external technology like VEGA.
  • Protagonist Title: Appropriately, the protagonist of DOOM is called the DOOM Slayer. Taken to exaggerated levels in Eternal. In her final audio log found in the Arc Complex level, Dr. Elena Richardson begins to worship the Slayer as a messianic figure, outright declaring him to be more than just a man, and that "he is DOOM."
  • Real Men Wear Pink: Despite being an incredibly intimidating killing machine built like a Belgian Blue, his collectibles are an ever expanding Super-Deformed action figure collection of himself and his enemies. He also owns a number of Doom universe versions of Children's Literature (like The Very Hungry Caterpillar, Green Eggs and Ham and The Giving Tree), Romance Novels, (like Fifty Shades of Grey and Eat, Pray, Love) and self-help books (like How to Win Friends and Influence People). With the Doomicorn skin or any variant thereof, he can quite literally wear pink.
    • With the reveal that this Doom Slayer is indeed the original Doomguy, it confirms that he used to keep a pet rabbit named Daisy. Doom Slayer also wrote a book called "My Best Friend Daisy".
  • Rebel Leader: According to the Codex, when the Night Sentinels started a civil war after discovering the true origin of Argent Energy, the Slayer led those who sided against the Khan Maykr, and was actually winning until the Betrayer sold them out.
  • Reconstruction: Of the Super Soldier trope - anyone who managed to become a One-Man Army who tore through The Legions of Hell with an unexplained Hyperspace Arsenal of guns wouldn't just be considered some random Mook for long. From the start of 2016, the Player Character is already Legendary in the Sequel, Shrouded in Myth, and considered to be The Scourge of God to the demons. In other words, he's become to them what Hell is for humanity.
  • Red Baron: The demons refer to him as the "Doom Slayer".
  • The Reveal: During the Sentinel Prime level of Eternal it's revealed he is in fact the Doomguy from the classic games who willingly remained in Hell at the end of Doom 64, only to somewhere along the line in his eons of battle end up in a portal leading to Argent D'nur.
  • Road Runner PC: One of the Doom Slayer's greatest strengths (second only to his Super Strength) is his incredible vertical and lateral movement - It allows him to keep his engagements to the range that is most effective at dealing with the individual foes, dodge projectiles and Ground Pounds and then close in for a Glory Kill once an opportunity presents itself. A double jump and a short-range borderline Flash Step doesn't seem like the most useful abilities when staring down the demonic hordes, but one of the reasons marauders are such absolute bastards to slay is because they can keep up.
  • Roaring Rampage of Revenge: He really goes apeshit on the demonic forces for destroying the realm of Argent D'Nur, and goes on such a ground-shattering vengeful rampage that it makes the collective forces of Hell piss themselves in fear, and only ends when they manage by luck on their part to seal him away. And that only bought them time. In Eternal, it's learned that this unrelenting rage stems from being betrayed by the Deagic Council, who pretended to be on his side and the side of the Night Sentinels, but who used their evil magic to scatter them and leave them all to die at the hands of the ravening demons, on top of losing his second home.
  • Sadist: Rather than going straight to the kill, if he gets his hands on a demon, he will gruesomely mutilate it just as the demons would do with him.
  • The Scourge of God: The Doom Slayer is a vicious and unstoppable killing machine, but he only aims his violent rampage against the wicked demons of Hell, who are utterly terrified of him and openly consider him this trope. One Slayer's Testament says that he got his Super Strength from "seraphim", implying that he may have literally been given his mission by God.
  • Screw Destiny: Oh boy. If it's supposedly written that humanity will fuel Urdak, then it's time for the Slayer to do some book burning.
  • Screw the Rules, I'm Doing What's Right!:
    • The Slayer is told several times in Eternal that killing the Hell Priests is an unforgivable violation of Night Sentinel law. Considering that the Hell Priests are trying to help Hell consume Earth's people, the Slayer does not once give a crap about what the other Sentinels think; even after being told that killing Deag Grav within the borders of Sentinel Prime will cause him to completely lose his status among the surviving Night Sentinels, the Slayer unhesitatingly blows his head off with the Super Shotgun anyways; when a group of Sentinels arrive to apprehend him, he only stays long enough to give them a rather contemptuous look before leaving through a portal.
    • The Khan Maykr is rather aghast that the Doom Slayer would willingly defy millennia of tradition to foil Urdak and Hell's attempt to consume most of humanity. Again, the Slayer doesn't give a crap about this; screw tradition, he's going to save humanity anyways.
    • Basically, he doesn't care about the consequences of his actions all that much. Because he'll shoot that as well
  • Sealed Good in a Can: Started off as this before the events of the game - the Demons, realizing that nothing they could throw at him would kill him, opted to instead bury him under one of their temples by collapsing it on top of him, then binding the rubble into a sarcophagus and sealing it with every damn ward they had. When the UAC found his coffin, the demons fought like they had never fought before to keep them from taking it - and with good reason: Less than five seconds after being awoken, The Doom Slayer is already killing possessed with his bare hands. Hayden then Book Ends the game by sending the Slayer somewhere (no doubt with the ability to recall him, should things to south again) via the Tether system.
  • Shell-Shocked Veteran: For a while, anyway. Fighting the hordes of Hell really did a number on his psyche, as shown by a flashback to the time he was Doomguy. By the time the Night Sentinels rescued him, he was reduced to a babbling wreck who sounded like he'd used one too many berserker packs, only speaking of demon genocide. And guts. Huge guts. By the time of the games, however, we have yet to see any sort of shell shock from him, implying that he has either moved past it, the divinity machine purged it, or he keeps it very well hidden beneath his Tranquil Fury.
  • Shoulder Cannon: The Doom Slayer's upgraded Praetor Suit in Eternal now sports the Equipment Launcher on the left shoulder - a mulipurpose ordinance delivery system capable of firing off a short-ranged Flame Belch, Frag Grenades and Ice Bombs.
  • Shut Up, Hannibal!: He deals with anyone who tells him he can't do what he's doing by making it violently clear that nothing will stop him.
    • When Deag Grav tells the Slayer that he can't kill him on sacred ground, the Slayer just shoots the Priest's head off .
    • Both Novik and the Betrayer separately attempt to convince him that he can't stop the Khan Maykr alone; his response is to completely ignore them after a brief Death Glare.
    • Deag Ranak attempts to bargain with him, offering him power and assistance in exchange for his life. He doesn't even finish the offer before having his head lopped off by the Doomblade.
  • Silent Snarker:
    • Eternal reveals that, as Doomguy, he was at least capable of speaking (although by the time the Maykrs found him, he was more or less reduced to reciting his Madness Mantra), but in the present-day, the Slayer does not speak a word, although he still grunts when hit. His actions and facial expressions basically do all the talking, such as him visibly having no patience for Samuel Hayden's tendencies to exploit Hell for resources and For Science!, and killing the Hell Priests mid-sentence. According to the codex, he is still capable of speaking, but simply chooses not to.
    • In Eternal, if you've run out of ammo for a gun and try to switch back to it, he takes out his chainsaw to silently remind you of how reloading works.
  • Sleeves Are for Wimps: By the events of Doom Eternal, the bicep armour on his Praetor Suit has been removed, revealing his gigantic muscles. Lampshaded as the description for the Original suit from 2016 is labeled "concealed guns".
  • Sole Survivor: Regardless if he's from an Alternate Universe Earth or Argent D'Nur originally, the Doom Slayer is this Up to Eleven: he didn't just lose the entire demon-fighting order he fought with, his entire homeworld was destroyed by Hell, leaving him seemingly the only one left. Then it turns out there are surviving Night Sentinels. Unfortunately, the ones that survived are working with the Hell Priests.
  • Soul Eating: As revealed in Eternal that Argent Energy is made from the souls of those killed by Demons, him absorbing the Argent Energy Cells for power means that he's been consuming the souls of the other victims of Hell.
  • Space Marine: Despite his Mysterious Past, his pressurized Powered Armor and records of his campaigns across the plains of Hell got him the moniker "the DOOM Marine" from the UAC researchers who studied him. In Eternal, it's revealed that he was once Doomguy, the lone human space marine who killed his way through legions of demons even before becoming a Sentinel.
  • Spanner in the Works: The empowering he underwent by the Seraphim as described in DOOM? That was actually one Maykr going against the Khan's wishes to create a reserve back-up plan in case things went sour. The Khan Maykr was displeased with this and exiled the Seraphim, but kept the Slayer around until he too was in the way of her plans with Hell. What she didn't count on was his absolute refusal to die, which resulted in a long-term destruction of her plans from the inside-out.
  • Spell My Name with an "S": Is it "Doom Slayer", with a space, or "Doomslayer", all one word? Official materials largely use the former, but the latter has also been used, so it seems either is permissible. Not unlike how older instances alternate between the fan-ascended nickname of "Doomguy" and the nondescript "Doom Marine".
  • Suddenly Voiced: He gets a voice in Eternal, but only for grunts of pain when he gets hit. Naturally, it's incredibly deep and guttural. However, Flashbacks to his first arrival on Sentinel Prime later in the game reveal he was perfectly capable of speaking, but was rapidly losing his mind by the time the Sentinels found him, and seems to have stopped speaking altogether by the time the Seraphim empowered him through the Divinity Machine.
  • Super Soldier: When the Night Sentinels first find him, he is merely a Badass Normal who took on Hell's armies by himself for decades. After some time spent training with them, he rises to become one of their best warriors, but when the Seraphim imbues him with the power of the Maykrs, he becomes far greater than any human or Sentinel.
  • Super Strength: He's strong enough to liquefy a zombified human's skull with just one hand while shackled to a table, rip off the limbs off bullet resistant demons, and tear apart pieces of metal equipment and armour with just his hands and feet.
  • Super Speed: Very downplayed compared to some of the other speedsters in fiction, but between his ability to Double Jump, Flash Step / Videogame Dashing, his enduring stamina, it's hard to argue that his mobility isn't beyond human.
  • Super Toughness: The Slayer can survive being shot out of railguns like a human bullet, straight into the wall of a building with enough force to shatter the wall and break through, and only needing a second afterwards to resteady himself. This same toughness also allows him to take hits that would reduce a normal human to paste, even if he's much better served dodging the hit instead.
  • Talk to the Fist: In Eternal, this is how he deals with the Hell Priests. When they're extolling the power of Hell or how they're supposedly untouchable, the Slayer shows how wrong this assumption is by attacking them mid-sentence. He tears off the first Priest's head with his bare hands, cuts off the second Priest's head with the Doomblade, and shoots the third one point-blank in the face with his Super Shotgun.
  • Teeth-Clenched Teamwork: It's clear that the Doom Slayer does not trust Samuel Hayden. But he's forced to work with him to stop the demonic invasion. Hayden likewise doesn't appreciate the Slayer's somewhat permanent approach to shutting down operations, but admits that the Slayer is possibly the only person who can stop them.
  • Terror Hero: By the events of Doom Eternal, his mere presence cause any human in the vicinity to visibly tremble and get them to keep their distance. He is sufficiently intimidating that he can even confiscate a UAC guard's plasma rifle with little more than a token protest that quickly stops when he delivers a Death Glare at the poor guy. Except for the guy at the ARC Complex though, who looks up to the Slayer like a fanboy rather than overtly terrified of him.
  • Time Abyss: The Slayer's Testament claims that no one even knows how long he's been slaughtering the forces of Hell, but his name is etched across the demons' history for eons. (An eon, in scientific terms, equals to a billion years.)
  • To Hell and Back: He goes to Hell and back three times that the player can see (when Olivia opens the portal at the Argent Tower, to retrieve the Crucible, and then to shut down The Well), and is said to have done it at least once before, which is how he became so damn scary to the demons.
  • Took a Level in Badass: Not that he wasn't already awesome from the start, mind you, but the collected lore in Eternal states that his Night Sentinel training and Seraphim enhancements turned him from the "brutal, but crude" Doomguy to the Great Slayer, the greatest Sentinel to ever live.
  • Too Spicy for Yog-Sothoth: He's gone to Hell multiple times and broke out every time (the ending crawl from the original game even says he's "too tough for Hell to contain") It gets to the point where the demons are downright scared of him and try hard to keep him OUT of Hell.
  • Touched by Vorlons: According to the Slayer's Testaments, he was granted superhuman abilities from the "Seraphim" (revealed in Eternal to be one of the Maykrs).
  • Trauma Button: The Slayer is extremely traumatized at the mere thought of demons and any he even thinks, sees, or hears about one of their kind he will let loose all of his rage.
  • Tranquil Fury: He never cries out in rage, not even once. But his mannerisms and the fact that he dispatches every demon, monster or zombie that gets in his way brutally and without a shred of mercy indicates that he is very, very pissed. In Eternal, only the part of his face visible through his visor is his eyes, which are locked in a permanent, enraged Death Glare. His state as this is especially pronounced when his present-day silence is put into direct contrast against his gibbering mania when he was first found by the Night Sentinels.
  • Unfortunate Name: With the confirmation that Doomslayer is Doomguy from the original games, it can be assumed that his name is either William Joseph "BJ" Blazkowicz III or Stan Blazkowicz. The latter and William are fine in themselves, but since BJ is short for "blowjob", things take a turn for the unfortunate.
  • Unscrupulous Hero: He is extremely violent and committed to his goals of eradicating the demons above all else, but his reactions to dead civilians and his treatment of VEGA indicate his moral compass is quite functional.
  • Unstoppable Rage: He is the Sole Survivor of his realm, and considering how he utterly brutalises any demon or possessed that get in his way as well as his lengthy rampage before he was sealed away, one could agree that the experience has left him with... anger issues. Eternal even makes it a gameplay mechanic, with extra lives being him getting so angry he literally refuses to die.
  • Unwitting Instigator of Doom: In Eternal, it's revealed that as the original Doomguy, he was brought to the Night Sentinels maddened and delirious, constantly rambling about the demons he's fought for so long. It's because of this that the Maykrs grew interested in finding said demons, and corrupted the Sentinels with the promise of Argent Energy once they found them, which ultimately ended up with the events of 2016 and Eternal unfolding. The Slayer isn't simply destroying the UAC's Argent Energy out of hatred for Hell, he's preventing the same mistake from happening again, to his own people.
  • Walking Armory: Downplayed come Eternal, he gets a shoulder-mounted cannon capable of firing several types of munitions, and the Doomblade attached to his left wrist - the rest of his equipment are still stored in a Hyperspace Arsenal.
  • Voice Grunting: In Doom Eternal, the Slayer makes grunts of pain whenever he takes damage. He's otherwise still presented as a Silent Protagonist.
  • Weapon of Choice: If both covers of the game are anything to go by, the Doom Slayer's weapon of choice is the double-barreled Super Shotgun. Both this and the regular Combat Shotgun are mainstays in the Doom Slayer's arsenal.
  • Well-Intentioned Extremist: The Doom Slayer will stop at nothing to stop the forces of Hell from consuming another world, even if it means undoing any good the UAC could have done with Argent Energy. Earth is stated to be suffering from a serious energy crisis, but the Slayer doesn't care, or doesn't think the UAC can keep the evil in its can forever. Come Eternal, he's proven right.
  • What Measure Is a Non-Human?: As far as we know, he's never killed another human being. It's open season on everything else, however.
  • World's Strongest Man: To quote Samuel Hayden:
    Hayden: "The Slayer has no equal"
  • Worthy Opponent: It's clear from the tone of the Slayer's Testament recordings found in Hell that, as much as the demons might fear and loath him, they hold the Doom Slayer in a twisted kind of respect for the pain and destruction he brings, even if it's directed at them.
  • Would Hit a Girl: Several of his opponents (namely, Whiplash demons, Spider Mastermind and Khan Maykr) are female, yet he will rip and tear them just like any other enemy of his.
  • Would Not Shoot a Civilian: The UAC's casual dismissal of their civilian casualties has him visibly trembling with rage. Eternal shows him walking through a UAC base on Phobos with living humans panicking over the invasion (and over him) and doesn't hurt a hair on any of their heads even if he's more than a little disrespectful with them. Not that this extends to any Demon of Human Origin though - it doesn't matter what it was, even if it was a civilian; if it's a demon now, it's dying. In fact, his entire crusade against Hell began because he assaulted a superior officer who ordered him to kill civilians.
  • Your Soul Is Mine: He is able to absorb strength from the fallen demons, which, in-game, is represented through the glory kill system.
  • Zero-Approval Gambit: In Eternal, before the Gladiator boss fight in Sentinel Prime, Deag Grav informs the Slayer that if he kills him as he did the other Hell Priests and thus spills Sentinel blood within the city, he'll lose all of his sovereignty and respect among the surviving Night Sentinels. The Slayer isn't fazed by this and, in the aftermath of the fight, kills him anyway with a Super Shotgun blast that blows his head into chunks. As soon as this happens, several Night Sentinels run into the arena he's in, slowly inching closer towards him as their now red-tipped spears point in his direction— a clear sign that they no longer tolerate his presence. The Slayer simply leaves, no doubt believing that putting a dent in Hell's invasion of Earth was well worth the cost of his good will with the Sentinels.
    • However, given that these are the same Night Sentinels who willingly sided with the Khan Maykr even after learning of her pact with Hell, it's likely that he doesn't really care if they respect him or not.


How well does it match the trope?
