In Remnant Inferis: DOOM, certain characters get picked apart and torn down throughout the course of the story.
- The Slayer himself ends up being a deconstruction of many things, to the point where almost his entire character gets ripped apart over the course of the story:
- '90s Anti-Hero: He checks every box off the list, from his jerkass attitude, to his gritty title and ruthless manner of dispatching his enemies no matter what they are. The change to a setting much Lighter and Softer than what he's used to emphasize how problematic this attitude is. Back on the UAC facility, he could get away with being a massive dick thanks to the only things there being demons for him to kill as well as only two allies who had the patience to put up with his attitude. On Remnant, he has to work with Ozpin and his allies, and they don't have any tolerance for his behavior. The only reason they put up with it is because he's their best chance at stopping Hell, so they don't have many options. In fact, many of them see him as either a monster, as much a threat as Hell itself, or a useful asset at best.
- The Berserker: His unrelenting rage and visceral brutality makes him one of Hell's greatest enemies. However, in a world besieged by monsters who feed off fear, hate, and other negative emotions, someone fueled entirely by their hatred just makes things worse. The Slayer always draws Grimm like moths to a flame, and the Grimm as a whole start acting far more erratic because of his presence. His hatred for the demons and the demons' hatred for him combined led to the Grimm invasion of Vale happening far earlier than it did in canon. A number of characters have called out that his presence has just as much worsened their problems with Grimm as it has improved their odds against Hell.
- The Bully Hunter: His aggressive actions against the bullies at Beacon Academy don't give him a good standing with the students or teachers. It's not that what he was doing was wrong, it's that the way he went about it is so brutal that it makes people less inclined to like him than the actual bullies he's trying to teach a lesson. Velvet in particular finds him to be just as monstrous as the demons and was very disgruntled that he was the one to save her and not the teammates that she puts her trust in, and Weiss finds that the sheer wrathfulness of his actions completely undermine whatever point he was trying to make. Additionally, it's shown that his actions didn't actually solve anything. Team CRDL just resolves to get stronger so they can get revenge on him.
- The Living Emotional Crutch: Throughout the story, Ruby ends up becoming extremely attached to the Slayer and relies on him for comfort as a result of all the trauma the demon invasion is causing her. This proves to be problematic, as given who the Slayer is, her attaching herself to him and taking part in the utter Hell that is his life just results in her getting more traumatized, as seen when she insists on following the Slayer, only for her and her team to end up trapped in Hell, which she comes out of as a near mess. Many characters even bring up that Ruby is too attached to the Doom Slayer for her own good. Case-and-point, when Jacques uses the tether system to teleport the Slayer away, Ruby breaks and later snaps.
- The One-Man Army: The Slayer is a downright unstoppable killing machine who's slaughtered countless demons and Grimm by himself. However, being so absurdly powerful without any of Remnant's standard power conventions like Aura and Semblance make him a nightmare not only for his enemies, but for the people that are supposed to be his allies. Everyone he works with, barring a few exceptions, is afraid of him and as such, loath him.
- The Paragon: In many ways, through strength, tenacity, and martial prowess, he's everything that a young Huntsman or Huntress should strive to emulate. Even what he does (kill demons) isn't that far off from killing Grimm. However, his nigh-endless quest to destroy the horrors that threaten the innocent has reduced him to a murderous, violent, genocidal killing machine with no regard for his own life. In the end, the person that a Huntsman should strive to be like ends up being someone that no one would ever want to be, and the Slayer wants no one to turn out like him either. He's essentially what a Huntsman could devolve into if one were to strip the occupation down to just killing monsters until their dying day with no comfort or respite in between.
- The Unfettered: The Slayer is completely unscrupulous and willing to do anything to stop the demons advance, one such example being suggesting killing the comatose Amber to prevent Hell or Salem from getting her half of the Maidens powers. However, despite the small shades of The Fettered that he does show, when we say "willing to do anything to stop Hell", we mean it. That includes destroying Epsilon, despite him knowing beforehand and outright being told that doing so would result in a massive ecological disaster that would cause Grimm activity to spike (and that's at a time when Grimm activity is at an all-time high) alongside rampant insurgency and crippling all four kingdoms' in one way or another, he still fully intends to go through with it. This willingness to do anything to stop Hell no matter the cost causes his allies to turn against him and try to stop him from achieving his goals as a result and he later gets branded as an enemy to the entire world when he succeeds in destroying the facility.
- Ruby Rose is often an idealist who looks for the best in everyone and believes that the life of a Huntress is like an adventure from a fairy tale. When the demons start invading, she's forced to wake up to the cruel reality of her world far earlier than she can deal with it. As the story progresses, the constant conflict and horror she's forced to witness breaks and disillusions her. She starts to become more aggressive towards the Legions of Hell, but she also develops a sense of murderous blood-lust, hunting and killing them with a smile on her face, and she eventually becomes just as cynical and ruthless as the Slayer, much to everyone's horror.
- Ozpin picks apart the Manipulative Bastard as well as secretive character tropes. Ozpin, while a good man at heart, does manipulate things so that the Slayer becomes someone more manageable through Team RWBY being a Positive Friend Influence to him. While on paper it's a sound idea, it doesn't quite pan out like he expects. The Slayer ends up being more of a Toxic Friend Influence on them than they are a positive influence on him thanks to how much utter Hell his life puts them through both figuratively and literally. Instead of making him a better and more manageable person, he ends up making them worse in one way or another. Being good at manipulating people, regardless of whether the outcome would be good or bad, doesn't mean your plan will always pan out. As for him being so secretive, it's something that causes a rift between him and the Slayer, as the Slayer knows he's being left in the dark on certain things, which just frustrates him and makes him harder to control. By the time they meet up again in the "Kingdom of Tyrants" arc, the Slayer makes it clear that he's tired of Ozpin's secrets and that he's going to confess the truth or else.
- Marv Talg is a Deconstructive Parody of the Incubus and Hot as Hell characterization of Succubi and Incubi popularized by characters like Morrigan. He's a hypersexual hedonistic demon, and one would normally expect him to be played for fanservice or something of the like much akin to others of his kind in more fantastical settings. Nope. He's shown to be a horrific sociopath who indulges in vice and rape as easily as breathing, and whatever attractiveness he has is undercut by the sheer horror of his actions. His indulgences are not considered cute, attractive, or remotely endearing in any way. They are shown to be repulsive and horrible, with all characters, including the villainous ones, reacting appropriately to him. He also, in many ways, harkens back to the original mythology surrounding the Succibi/Incubi and how they and their actions were portrayed; with horror and disgust.
- Canonically, Jaune ripped apart the Butt-Monkey archetype, but his portrayal in this story instead deconstructs the side/background character. In his rant to Pyrrha, it's shown that he's painfully aware that he's merely a footnote in someone else's story and has further insecurities about how someone else is always saving the day with him barely doing anything of value that contributes to the heroes efforts to save Remnant. Exacerbating matters is that he's going through as much hardship as the main characters yet has gained nothing for it. His main goal is to get on the heroes' level and become more active in the fight against Hell so that all the trauma he's had to endure wouldn't have been for nothing.
