Fanfic / What the Cat Dragged In

What the Cat Dragged In is a Miraculous Ladybug/Marvel Cinematic Universe fanfic written by Kryal.

Tony Stark, Natasha Romanoff and Clint Barton (better known as Iron Man, Black Widow and Hawkeye) are sent to a Parisian tech-and-fashion exposition to examine a prototype suit, commissioned by S.H.I.E.L.D. and designed by Gabriel Agreste, for agents who need formalwear that isn't restrictive in emergency situations. Unfortunately, an Akuma attack breaks out on the convention floor, and the three Avengers wind up caught in the middle of it — thus introducing them to Paris's own homegrown superheroes, Ladybug and Chat Noir.

This takes place, timeline-wise, between The Avengers (2012) and Iron Man 3.

What the Cat Dragged In provides examples of:

• Actually Pretty Funny:
  • Clint decides that Ladybug riding Peacemonger like a bucking bronco is this, even realizing that he finally has a joke that would embarrass Tony "What-Is-This-Shame-Business" Stark.
  • After the final battle, it's mentioned that once they got over their initial terror, Rose and Juleka had fun flying over the city in Iron Man suits.
• Adaptation Deviation: Ladybug and Cat Noir do not actively patrol for Akumas rather than waiting, since the author felt it was illogical that two school kids would have the time to do that.
• Adults Are Useless: Not only are Ladybug and Cat Noir teenagers, but a bunch of high-school students do far more to deal with the aftermath of the akuma attacks than the adults. Tony is not happy about that.
• Affably Evil: Peacemonger speaks politely, and doesn't hesitate to call the heroes "rude" for trying to escape him.
• All Men Are Perverts: Defied. Adrien, ever the gentleman, closes his eyes when he ends up under Seamstress while running away from her, so that he won't look up her skirt. Tony actually takes note of this as he can't believe a Hormone-Addled Teenager would resist a chance like that.
  Somewhere in the back of his mind, Tony had to blink.
  …did he seriously just close his eyes so he wouldn't look up her skirt?
  Someone call the cosmic police, it had to be against the laws of the universe for a teenage boy to be that polite.
• And Now for Someone Completely Different: The main story focuses on the Avengers. The epilogue chapter follows Ladybug and Chat Noir discussing recent events two weeks after the Avengers pull out.
• Animated Armor: Peacemonger is able to trap other people in Iron Man suits and use them as his army.
• Arkham's Razor: Due to the fact that all methods of recognition (from simply looking at them in person to the use of advanced government recognition software) fail to decipher Ladybug and Chat Noir's true identities (even simple things like their age-range), as well as the unlikelihood of Ladybug and Chat Noir's identities remaining a secret despite public security technology like cameras, S.H.I.E.L.D. has reluctantly come to the conclusion that they operate on a magical glamour.
• Armor-Piercing Response: Tony delivers a brutal one to Alya when she fantasizes about unmasking Ladybug and Chat Noir.
  Alya: People deserve to know who their heroes are! How else are we supposed to thank them?
  Tony: Well, I'd suggest starting with not destroying their civilian lives, myself.
• Ascended Fridge Horror: Early on it's discussed how much of a risk the Akumatized people are already, and then Black Widow mentions that things would get a lot worse if the Avengers or some S.H.I.E.L.D. higher-up were Akumatized or mind-controlled by an Akuma-empowered person themselves (such as the Puppeteer), which makes even a Deadpan Snarker like Tony feel nervous (although he insists that S.H.I.E.L.D. should provide help regardless). And then in the final chapters, Tony is akumatized into Peacemonger and becomes one of the hardest akumas that the Miraculous duo has had to beat by a pretty wide margin, even with Hawkeye and Black Widow helping them.
• Audience Surrogate: Tony acts as one for Avengers fans who are unfamiliar with Miraculous Ladybug. He often asks the questions that non-fans would be expected to ask.
• The Bad Guy Wins: Downplayed; both of Hawk Moth's akumas end up defeated, but he does achieve a victory in the form of indirectly making sure that Ladybug and Chat Noir won't be able to get direct help from S.H.I.E.L.D. or the Avengers.
• Berserk Button:
  • It's heavily downplayed, but after the incident with Loki, Clint does not like the idea of mind control.
  • A few of Tony's are pushed when Fury decides the best course of action towards the akumas would be for the Avengers to leave the city. It gets him akumatized.
  • Another downplayed example is when Peacemonger tells Chat Noir to hand over his Miraculous for his own safety. In response, Chat Noir growls and tells him "I am sick and tired of being kept safe for my own good!"
• Bittersweet Ending: After the Peacemonger incident, Tony ultimately agrees that having the Avengers or S.H.I.E.L.D. operate in Paris would be too much of a risk, forcing them to pull out and leaving Ladybug and Chat Noir without their direct aid. However, their conversations with the other heroes help the Parisian heroes make great advances in directly coordinating with each other, and all sides end up with a closer bond than they did previously.
• Brick Joke: In the first chapter, Adrien recognizes Natasha from the Battle of New York and advises her to steer clear of Chloé, because if the heiress recognizes her she'll probably force her to take selfies with her. In the last (pre-epilogue) chapter, as the Avengers are leaving, Nino tells them they picked a good time to do so — because Chloé finally figured out that Natasha was in Paris and ended up throwing a tantrum over her departure.
• But for Me, It Was Tuesday:
  • Chloé's been responsible for so many Akuma that Ladybug isn't even surprised anymore.
  • Juleka's reaction to Peacemonger.
• Bystander Syndrome: Tony is utterly disgusted by the unwillingness of everyone around him to do anything about Hawk Moth unless they are directly endangered. As Peacemonger, he decides to make them stand up for themselves.
• Cabin Fever: Tony suspects that Adrien has this up to eleven if his idea of getting off his climbing wall was to launch away from the wall toward the couch.
• Casual Danger Dialogue: Tony engages in some of this while fighting the Seamstress.
• Catharsis Factor: In-Universe, Natasha figures that akumatization might count as this.
• Chekhov's Gun: Applied physics. Originally brought up when Tony learned about Adrien's research on Ladybug and Chat Noir, the latter ends up namedropping it for his plan to defeat Peacemonger.
• Chivalrous Pervert: Tony Stark will not flirt with an underage woman, with Natasha managing to figure out that Ladybug is a teenager when she realizes that Tony never flirted with her even once, having subconsciously recognized her as underage despite the effect keeping people from recognizing Ladybug and Chat Noir's faces keeping him from consciously guessing her age.
• Cliffhanger: From the last chapter:
  Plagg: Kid? I want a camera.
  Adrien: Why...?
  Plagg: Because when you learn who Ladybug is, your face is going to be better than cheese.
• Composite Character: Ladybug and Chat Noir decide that Peacemonger is a Black Knight take on Rogercop, with Lady Wifi's cleverness.
• Conversational Troping: Pops up on occasion.
• Cuteness Proximity: Both Ladybug and Natasha want a copy of the picture of Chat Noir tangled up in string during the Seamstress fight.
• Cyborg: Peacemonger without his armor might be this, given how he's described as having repulsors in his hands and looking like a human circuit board.
• Destination Defenestration: Natasha pulls this in order to escape Peacemonger.
• Dissimile: "Tony Stark was known for his patience in the same way that deserts were known for their humidity."
• Dramatic Irony: Before leaving Paris, Natasha gifts Marinette a USB drive and tells her to pass it on to Ladybug, also warning her not to give anyone a reason to figure out that she knows Ladybug (since she helped Alya set up an interview with the heroine). The reader, of course, knows that Marinette herself is Ladybug.
• Entropy and Chaos Magic: From seeing Ladybug and Chat Noir in action, Natasha and Clint are able to accurately deduce that not only are their powers magical in origin, but they operate on a system of magic based around probability. Adrien also argues for this, having studied several Akuma battles himself; he describes the effect of Chat Noir's Cataclysm as "concentrated entropy".
• Even Evil Has Standards:
  • When Peacemonger traps Rose and Juleka in suits of armor, he sends them as far away from the main battlefield as he can instead of forcing them to fight for him, due to the fact that they're minors. Which only disturbs Clint and Natasha, because they can totally imagine Tony making the same choice.
  • Similarly, while he's willing to take Ladybug and Cat Noir's Miraculouses in the name of keeping them safe, he isn't willing to actually hurt them. So when Ladybug lassos and starts riding him, he just tries to shake her off instead of squashing her against a building.
• Everyone Can See It: It takes all of a minute of seeing them interact for the Avengers to spot Marinette's massive crush on Adrien, much to their amusement.
• Evil Only Has to Win Once: Discussed in Chapter 4. Hawk Moth doesn't lose anything but time when his akumas are defeated, and the glamour seems to make it impossible to track where akumas appear from or disappear to. In short, Hawk Moth can keep trying as many times as he wants, until eventually one of his akumas gets the Miraculouses.
• Face Palm:
  • Natasha performs one when she learns that Chloé finally learned that she was in Paris.
  • Ladybug also does one when she learns that, during the Evillustrator incident, she left Chat Noir with Chloé for an hour.
• Foreshadowing: When talking to Fury about pulling out of Paris, Natasha mentions spotting a pattern in terms of akumatizations — when a bystander actively helps Ladybug and Chat Noir, that bystander is usually the next one to get akumatized (e.g. Jagged Stone helped them fight off Pixelator, and was subsequently transformed into Guitar Villain). Hawk Moth's next target ends up being Tony, who'd helped Ladybug and Chat Noir fight off the Seamstress previously.
• Genre Savvy:
  • Adrien can immediately tell that Blanche Bissette is going to get akumatized after the poor woman's encounter with Chloé. Unfortunately, he's right.
    Adrien: Please tell me someone really did go after Blanche?
    Clint: Not that I saw.
    Adrien: [wincing] That's... not good.
  • The author's notes suggested that the Mayor was this regarding Nick Fury's involvement in the akuma problem.
    "...Mayor Bourgeois is just Genre-Savvy enough to look at Fury, look at the Significant Naming that pops up all over the place in Miraculous Ladybug, and think, Oh dear God this man is a supervillain waiting to happen get him out of town now!"
  • When dealing with an akumatized Tony, Natasha is quick to realize that his fondness for the Evil Overlord List makes him this — e.g., he'll likely avert Conservation of Ninjutsu and send his entire army of robotic suits after the heroes.
• Gilded Cage: Discussed in regards to Adrien's room. At first glance, it looks like any teenage boy's dream bedroom, with two and a half floors of space and all the fun amenities a teenager could ever want. However, on closer inspection, Tony realizes that it carries the same sort of suffocating perfection as the rest of the Agreste mansion; there's no personal touch, no mess, nothing to indicate that a teenage boy actually lives in it. Most jarringly is the row of arcade machines — there's a DDR-like dance machine among them, custom-made so there's only one pad instead of two, carrying the implication that Adrien's father doesn't want him bringing friends into the house.
  "All of a sudden, that glorious wall of windows seemed less about the windows and more about the bars."
• Glamour: Ladybug and Chat Noir have one that protects their identities. That said, it's not invincible; Tony subconsciously recognizes Ladybug as a minor and does not flirt with her, and Natasha picks up on this and uses this to partially break through the glamour and deduce that the two are teenagers, as said in Chapter 4:
  Natasha: So even though the glamour prevented you from putting a specific age on Ladybug, it didn't change the fact that you knew she was underage by American standards – so you acted accordingly.
• Godzilla Threshold: Tony flat-out says the trope's name when he sees Ladybug's Lucky Charm at work in Chapter 2.
• Going for the Big Scoop: Nadja Chamack, as usual for Miraculous Ladybug. She interviews Peacemonger on his plans to privatize world peace, and gets trapped in a set of armor for her troubles.
• Gratuitous Japanese: It's noted that "Akuma" isn't a French word.
• Greater-Scope Villain: Hawk Moth never directly appears in the story. At least not in his transformed state...
• Guest-Star Party Member: Tony, Clint, and Natasha serve as this for Ladybug and Chat Noir.
• Heroic Sacrifice: Rose tries to do this in order to keep Peacemonger from getting to Juleka, but the latter refuses to leave her behind. Peacemonger ends up getting both of them.
• Hidden Depths: Everybody who sees Miraculous Ladybug knows that Adrien can be surprisingly intelligent (being fluent in Chinese, for example), but this tale has him demonstrating intelligence on a level that impresses Tony Stark.
• Holding Out for a Hero: Pondering this trope triggers Tony Stark's akumatization. He has just realized that the fate of Paris is on the shoulders of two teenage kids whose personal lives have probably become an ungodly mess, and no one — not in Paris, not even in S.H.I.E.L.D. — seems inclined to step up and lend a single hand until the fighting's safely over.
• Hold the Line: Tony, Clint, and Natasha's objective for the first part of the fight against Seamstress is to hold out until Ladybug and Chat Noir arrive, since they have no way of non-lethally subduing her or purifying the akuma.
• Hope Spot: It looks like Natasha's lighter is going to take care of all the threads created by the Seamstress — until the villain rips through the fire suppression system and turns on the sprinklers.
• Incredibly Lame Pun: Naturally, Chat Noir gives us some puns over the course of the story. Tony also has a few of his own.
• I Resemble That Remark!: Said word-for-word in chapter 6.
  Clint: (to Natasha) I think we just witnessed the creation of a monster.
  Tony: I resemble that remark.
• Ironic Echo: The name "Peacemonger" strongly resembles Obadiah Stane's villain name (Iron Monger), something Tony notices immediately.
• Jerkass Has a Point: Nick Fury, in his own inimitable way, calls "hell, no" to the idea of helping in the Hawk Moth situation and explains how Hawk Moth is a humongous Outside-Context Problem in which the Avengers are just a bigger potential harm than good. Tony is forced to admit Fury is right after becoming Peacemonger, ironically because arguing with Fury made him mad.
• Kicking Ass in All Her Finery: Nick Fury commissioned Gabriel Agreste to produce a special line of suits designed to provide full freedom of movement and be resistant to incidental wear and tear, while still looking good enough for the most formal of events.
• Kick the Dog: Once again, Chloé's Alpha Bitch brattiness is the cause of an Akuma attack, by accidentally dumping red wine on a woman's white dress (that she'd made herself) and both refusing to say she's sorry and then mocking the woman when she runs off crying. When Adrien hears about it, he immediately fears the worst and tries to send somebody to help the woman... just a couple of seconds before she barges back into the room, akumatized into "The Seamstress" and looking for Chloé's blood.
• Kid Hero: Examined thoroughly. For the most part, the Avengers (especially Tony) are horrified that the fate of Paris rests on the shoulders of two teenagers. However, it's pointed out that being minors gives them a small safety net since they are not responsible for keeping a roof over their heads or food on the table.
• Know When to Fold 'Em: After analyzing the situation, Natasha and Fury conclude that any aid they could render towards Ladybug and Chat Noir would be outweighed by the horrific risk of an Avenger or S.H.I.E.L.D. agent getting akumatized, and decide to pull out of Paris entirely. Tony is enraged at first, but comes around once he is purified of his own akumatization.
• Leaning on the Fourth Wall: At one point Tony feels like he's in "some sort of French anime".
• Light Is Not Good: Peacemonger's armor incorporates a lot of white and gold.
• Living Clothes: The Seamstress animates pieces of clothing and uses them against the heroes. She's also able to take control of clothing already being worn, much to Tony's consternation.
• Master of Threads: The first villain in the story is a woman named the Seamstress. She has the power to animate clothing.
• Meaningful Name:
  • Blanche^note French for "white" Bissette first appears wearing a white dress. Her last name is also similar to "bisset" (weaver), referring to how she made the dress herself.
  • Mayor Bourgeois, being Genre Savvy, took one look at a man named "Nick Fury", and kicked him out of his office, not wanting to see how far this trope would go if he became an akuma.
• Motive Decay: Discussed by Tony in a hypothetical situation where Hawk Moth gets the Miraculouses.
  Fury: Hm. Papillon. What do we have on him? Do we have any idea what his objective is?
  Clint: Honestly? I don't think it matters. Pretty obvious he's got one short-term goal — grab these Miraculous things from Ladybug and Chat Noir. If he manages to get that far...
  Tony: Then it doesn't matter what he thinks he's after. Trust me, I know the type. This is a guy who doesn't see people, he sees tools for getting what he wants. People like that don't let go of power once they've got it. If he gets Ladybug and Chat Noir's Miraculous – well, it's not going to take long before he starts thinking things like, what else can I get away with, now that there's no one to stop me? Thus far, he's been too focused on going after Ladybug and Chat Noir directly to pull anything else. Take them out of the picture, though, and there's going to be trouble.
• Names to Run Away from Really Fast: Mayor Bourgeois considered Nick Fury to be an akuma waiting to happen and threw him out of his office before something went wrong.
• Nightmare Fuel: In-Universe, Tony describes the idea of an akumatized Captain America as this. It's also why S.H.I.E.L.D. is against going in and helping with Hawk Moth — agents with compromising intelligence, or worse, Enhanced or Avengers getting akumatized, is very much a nightmare scenario in their eyes.
• Noodle Incident:
  • This thought of Tony's:
    Tony: [thinking] Note to self, make joke about video game characters progressively tearing off bits of their costumes to symbolize Taking Levels in Badass, or else Clint's going to get going on Tarzan jokes and I will be obligated to initiate World Prank War III and they'll take my superhero license away again.
  • One of the more memorable foes Natasha has faced was apparently Nick Fury suffering "the hangover to end all hangovers".
• O.O.C. Is Serious Business: Despite the glamour that masks Ladybug and Cat Noir's identities, Natasha is able to determine that Ladybug is a teenager by noting that Tony was never tempted to flirt with her. Especially significant in that he wasn't at all hesitant to distract the Seamstress with an innuendo.
• Outside-Context Problem: One of the important plot points early on is that S.H.I.E.L.D., who have dealt with everything that the Marvel Cinematic Universe has tossed at them since its inception in the Fifties (including alien invasions, super-tech and superhumans) have absolutely zero clue on how the hell to deal with the Akuma problem, mostly because they have no idea of the true extent of the powers of a Miraculous or those who have been Akumatized. By the end of the story, even Tony agrees that this lack of knowledge is a big hurdle.
• Perception Filter: The Miraculouses come with a protective glamour that keeps people from deducing the identities of the Bearers, either directly (i.e. it's impossible to make a connection between "this is what Ladybug looks like" and "this is what this particular civilian looks like") or indirectly (i.e. it's impossible to make the connection between "this civilian disappeared into this alcove" and "Cat Noir came out of this alcove").
• Pet the Dog: Gabriel Agreste sincerely praises Blanche Bissette's work on her dress, something which had to take much time and effort.
• Police Are Useless: Subverted. While it's true that a rampaging Akuma is something they cannot deal with directly, it's pointed out that the Parisian police has been helpful in preventing people from being caught in collateral damage, and they have created a sub-division to help the Akumatized deal with the shock of having been turned into monsters after Ladybug de-evilizes them.
• Properly Paranoid: Fury decides to withdraw from Paris because he fears the consequences of a S.H.I.E.L.D. agent or an Avenger being akumatized. Sure enough, Tony gets akumatized five seconds later.
• Ranged Emergency Weapon: Unable to summon the full Iron Man suit in his fight with Seamstress, Tony reveals that he was prepared for that kind of situation — he's got a modified version of one of his repulsor gauntlets in his traveling bag. The "emergency" part comes from the fact that, without the rest of his armor to handle the recoil, the power output of said gauntlet isn't much to write home about. This is actually consistent with what is seen in the films — in the first Iron Man, he tests out the hand repulsor on a few panes of glass to blow off steam after he hears about the Ten Rings using his weapons on TV, Iron Man 2 showed he can put the entire suit in a suitcase (in a more limited form), and Captain America: Civil War shows him using a nearly identical device to fight against Bucky.
• Sadistic Choice: Akumatized Tony Stark/Peacemonger. The akuma possesses his arc reactor, the very thing keeping Tony alive. Breaking it means causing a massive explosion (because, you know, reactor). Removing it means Tony either dies or gets that much closer to death the next time it's removed. Leaving it in means Tony remains possessed.
• Screw This, I'm Outta Here: Fury ultimately realizes that the best thing the Avengers can do for the crisis in Paris is to pull out and leave it to the local experts. He realizes that any aid they could offer Ladybug and Chat Noir is offset by the potential danger of an Avenger or someone with sensitive information getting akumatized.
• Skewed Priorities: Once Chat Noir enters the battle with the Seamstress, Tony's first instinct is to question his outfit.
• Smarter Than You Look: Tony gets this feeling about Adrien from the first moment he sees him, but the moment they talk to Adrien at his home and discover that he's been breaking down the magics of Chat Noir's abilities into physics terms as a hobby (specifically, he theorizes that Cataclysm is accelerated entropy), Tony instantly makes him a standing offer of an internship with Stark Industries and asks why is he even bothering to be a model with such a mind (regardless of what Gabriel Agreste thinks).
• Stop, or I Shoot Myself!: This is one of the two big reasons why Fury dares not get the Avengers involved in the Hawk Moth situation. Neither S.H.I.E.L.D.'s weapons nor the Avengers' powers are terribly suited to fighting a battle without harming the person they're fighting, and they have no guarantee that Ladybug's ability to reverse the damage inflicted by the akuma and the Miraculouses themselves will extend to reversing damage inflicted by a third party.
• Superman Stays Out of Gotham: When Tony asks why the hell isn't S.H.I.E.L.D. providing assistance regarding the Hawk Moth situation (pointing out that the agency's resources should make dealing with him an easy thing, or so he thinks), he is told back that Mayor Bourgeois pretty much kicked Fury out of his office when he arrived to provide the offer and flat-out refused, saying that the Parisian authorities and the Miraculous holders could deal with it pretty fine by themselves. Fury ends up agreeing (and thus denies Tony's request to send the Avengers) when he points out that the agency has very little clue of how the Akumas operate and the true extent of their powers, and he won't risk the potential escalation.
• Suspiciously Specific Denial: Name-dropped in an author's note when talking about why Ladybug wants a picture of Chat Noir.
• Tempting Fate: "She's attacking us with granny's knitting, how bad can it be?" asks Tony about an akuma right before finding out.
• There Are No Therapists: Averted. One of the few things the Paris government does right in handling the akuma situation is to get counseling for victims after their possession, facilities Tony makes use of after Peacemonger is defeated.
• This Is Gonna Suck:
  • Clint's reaction to Tony getting akumatized?
    Clint: Well, nuts.
  • Chat Noir has a similar reaction when they realize that the akuma is in Tony's arc reactor, meaning it is behind his armor, it is keeping him alive, and it could take out half of Paris if they destroy it.
    Chat: ...this would be a purrfect time to start swearing. Unfurtunately, I don't think there are any words strong enough.
• Touch of Death: Tony points out that Cat Noir's Cataclysm could be used as this, if he were willing to go lethal.
• Trauma Button: Mind control is still a touchy issue for Clint after what happened to him at Loki's hands.
• Two-Timer Date: Speculated to be part of Hawk Moth's strategy. Ladybug and Chat Noir cannot afford to let anyone know their true identities, which means they have to drop everything and disappear on an almost daily basis, without being able to explain what's actually happening. Given enough time, this will absolute wreck their civilian lives, to the point where they may themselves become vulnerable to akumatization.
• Unexplained Accent: Subverted. While Tony knows French, he has a clear American accent. As Peacemonger, his French is much more fluent.
• Unwitting Pawn: The heroes theorize that Hawk Moth may be using Alya as an unwitting patsy to search for Ladybug and Chat Noir's identities. Alya has something of a Heroic BSoD over the idea that the Ladyblog may actually be making things worse.
• Wake Up, Go to School & Save the World: Discussed and deconstructed by the Avengers when they figure out that Ladybug and Chat Noir are teens, not because they are "Just a Kid", but because living this kind of life is destructive in the long term due to sheer exhaustion. On the other hand, having a family to provide food and roof is pointed out to be a safety net that they would not have if they had to work for it.
• Walking Spoiler: Peacemonger. We can't even say his name without giving you a good idea of who got akumatized into him.
• Well-Intentioned Extremist: Peacemonger is this. He wants to teach the people of Paris that they shouldn't hide behind political figures and superheroes and learn to fight for themselves... except he does so by forcibly trapping them in suits of armor and attempting to take away the Miraculous.
• Wham Line: "Against the dark sky beyond those lights, fluttering black wings were nearly invisible — until the butterfly set down just for a moment atop the bright circle of the arc reactor."
• Willfully Weak: Tony points out that Chat Noir could be a terrifying opponent if he used his abilities to their full potential. Night vision + super-strength and reflexes + Touch of Death = almost unstoppable assassin.
• Wins by Doing Absolutely Nothing: After assessing the situation in Paris, Nick Fury ultimately decides that being as uninvolved as possible is the best course of action. With the glamour-based magic used to cover their tracks, learning Hawk Moth's location and identity is a fruitless endeavor and a waste of time. Even worse, no one has any idea how much of his victims' knowledge Hawk Moth has access to; if he ends up akumatizing another S.H.I.E.L.D. agent, he may be able to steal secrets. Ladybug and Chat Noir are the only ones who can fight a force as powerful as the akumatized villains, with Ladybug the only one capable of containing the akuma and fixing all of the damage that they cause on a daily basis. Tony is against this at first, but he changes his mind after nearly destroying everyone when he himself gets akumatized, which — as Fury notes — is probably the only thing that could have changed his mind. And while it's not mentioned in-story, the concept of Hawk Moth using his gifts to akumatize the one Avenger who would be most vulnerable to his methods — the Incredible Hulk — would be exceedingly bad. Just take a look at what he did to Johannesburg.
• Worf Had the Flu: Tony and Clint have a remarkably poor performance against Seamstress because neither of them brought their full superhero kit with them. Which makes sense, since it was at a fancy gathering, and while Tony can (and has) worn the Iron Man suits to formal gatherings, they shouldn't bring the flying battlesuit or a bow and specialized arrows.
• Worldbuilding: There's a lot of this on the Miraculous side of things.
• Wouldn't Hurt a Child: Even though he's been akumatized, there's still enough of Tony inside Peacemonger to get Juleka and Rose out of the line of fire and refuse to kill Ladybug in order to take her Miraculous.
• Wrong Genre Savvy: After Chloé ruins a woman's dress and mocks her, sending her running off in tears, Tony tells Adrien that he should give her a few minutes of privacy. While this would be good advice in any realistic setting, he's in Miraculous Ladybug, people with emotional breakdowns get driven murderously berserk by dark magic, and you really can't afford to take your eyes off people in this state (as said woman proves).
