History NightmareFuel / MiraculousLadybug

* One would think after her exposure for what she really was, that she'd be out of the picture as a regular but terrible person? ''Wrong''. Lila Rossi is revealed to have never really existed ''at all'', discarding her identity with ease to become Cerise. It frankly turns everything known about her upside down. Who is this girl really, if she has a completely different identity all this time that she can discard the persona seen for so long without a second thought? ''Why'' is she doing all of this in the first place, and for what reason? It's an understated horror that for all seen about her, that her true identity is a complete unknown... and she's ''still'' on the loose.

* It also shows not even Lila/Cerise's allies are safe. While she doesn't directly make their lives miserable, she will abandon them the moment they served their purpose and leaves them with the consequences of their actions. She also acquired a laptop holding data on the Alliance System and is now her more dangerous, to both the heroes and Gabriel along with everyone else.

* Cat, while possessed by the titular akuma, comes within an inch of using [[MakeThemRot Cataclysm]] on Ladybug. If not for Chloé's intervention, she wouldn't have survived.

* Riposte would have slayed Ladybug if Adrien hadn't safed her at the very last moment.

* Ivan and Myléne almost falling to their deaths, especially in Ivan's case where it happens because he transformed back while hanging from the Eiffel Tower but was unlucky enough for the de-akumatization to cause him to no longer hold on, and because he didn't remember how he got there. Ladybug and Cat Noir have to think fast to save them both ''and'' purify the akuma.

* Marinette's mental breakdown, being one of the closest times she get Akumatized and this time not the result of another's malicious intent.

* While not attacking anyone except when provoked, Kagami's form as Ryukomori is an embodiment of her suicidal despression.

* Even though it's LaserGuidedKarma, Audrey makes it clear to her daughter Chloé that SHE blames ''her'' for tarnishing the Bourgeois family name, and intends to control every aspect of her child's life. Considering that Mrs. Bourgeois had a direct role in shaping Chloé's toxic personality, this isn't just a case of her [[NeverMyFault refusing to recognize her own fault]] for the way her daughter turned out, but makes it clear she's about to be even ''worse'' to Chloé like she was to Andre before he found the courage to finally stand up to them.

* Rose's chronic illness which she kept from all her classmates but Juleka, fearing everyone would treat her differently due to frequent trips to the nurse's office. Juleka is also effected as Rose's SecretKeeper in not wanting to let her friend down while also fearing she would not be able to help her in the long run.

* Lila/Cerise, having acquired the Butterfly Miraculous, sets up her enrollment at the same high school that Marinette is attending. With Gabriel dead, she intends to give Marinette her full revenge-driven attention; both as Iris Verdi and the new Hawk Moth.

* The Supreme. Its never revealed who (or what) he is, but he's the reason that Shadybug and Claw Noir's universe is such a CrapsackWorld. He rules over the world as a ShadowDictator and has almost all the Miraculous of his world under his control. The closest he comes to actually appearing is when Shadybug attempts to make a wish using her and Claw Noir's Miraculous, only for it to be revealed that he placed a spell on them that prevents Tikki and Plagg fusing into Gimmi. The fact that the Supreme's influence on Kwamis is continuous in any universe shows him to be greater threat to the multiverse if he wanted to expand his dominion.

* The Miraculized, being an army of Alliance users who were subjected to Nightormentor's power and then recieve an app that would calm them before brainwashing into thinking Ladybug and Cat Noir have kidnapped Adrien and Kagami. The fact that most of the Earth's population become an army that can track Ladybug and Cat Noir and use Miraculous powers is horrific enough, as Marinette finds herself literally fighting the world.
* A weakening Nathalie confronting Gabriel in his repository with a crossbow and he willing admits to sacrfice someone to bring Emilie back.

** Also, remember the deadly looks many Akumatized people make before assuming villian form? Here's one for Lila, a SlasherSmile [[https://miraculousladybug.fandom.com/wiki/File:Volpina_207.png in all its glory.]]

* Monarch is cornered by Ladybug and Cat Noir after [[BatmanGambit a fake scavanger hunt]] the heroine organized herself leads him into an ambush. He nonetheless escapes... by allowing Cat Noir to accidentally '''''Cataclysm him'''''. Consequently, when he detransforms, his arm has a large, nasty-looking black scar that cannot be instantly healed due to taking Ladybug's lucky charm with him. In short, it took Gabriel a ''very'' near-fatal move to escape the heroes' clutches, and Cat Noir is justifiably [[MyGodWhatHaveIDone mortified]] at what just happened. Later episodes show the consequences of Gabriel's gambit as he is [[YourDaysAreNumbered slowly dying]] in a matter similar to terminal Cancer.

* Tomoe forcing her way into Gabriel's chambers and attacking him with her Bokken, threatening to destroy his dream if he ever endangered her daughter again. While Tomoe is a member of Gabriel's inner circle and provider of the Alliance System, it's clear that she is willing to let Gabriel die to keep her daughter safe.

* Adrien and Kagami are locked up in white torture rooms with cameras watching and recording them, no windows, and there's no chance of escaping again. Meaning Adrien's ''literally'' living in his worst nightmare.

** Alya wonders what is Ladybug doing when seeing this and even tries calling Marinette, only for it to go to voicemail everytime.

** Not even Lady Dragon can resist their stings en masse.

** Lila best displays how dangerous she can be when she turned most of Dupont College against Marinette on multiple occasions when she refuses her offer of being her friend, socially ostracize her to the point that she's stuck in the bakery more or less for her own safety... and Lila left no evidence of her wrongdoing. She would be one of the very few people who can directly and intentionally push Marinette into leaving herself open to get Akumatized. While forced to leave Dupont College, Lila continues to harrass Marinette in high school by creating the identity of Iris Verdi.

* In real-life, Jeanne D'Arc's death drove her comrade and closest friend Gilles de Rais to maddness before was he executed for ritualistically killing children. Within the series storyline, Jeanne faked her death and discarded the Ladybug Miraculous with her memory as Scarlet Fate and of her role in French history erased from her mind as consequence. Imagine the horror if she knew that faking her death would cause one of her dearest friends to become a murderer with the blood of innocent children on her hands.

* An upset Plagg gleefully admitting to [[EvilIsPetty wiping out the dinosaurs for making fun of him]], right after Zoe keeps him from attempting the same thing on Chloé.

* Hoaxer's ability to brainwash people connected to Alliance into believing whatever she types on the social media platform, from forming an angry mob to attack Marinette by making them think she's Monarch to maniuplating Natalie into providing blackmail on Gabriel all while keeping the latter in the dark of her true plan. Furthermore, it all hints to be the start of the Hawk Moth that suceeds Gabriel.

** The Marinette who became Shadybug suffered the same trauma her prime universe self suffered atChloé's bullying without the presense of Alya or a mother, missing or negliectful, in her life. Upon learning the life of her prime universe counterpart, Shadybug is consumed with envy to make a SwappedRoles wish. This results in her attaking Ladybug so she can use the prime universe's Gimmi after learning she can't use her universe's version.

** Alya wonders what is Ladybug doing when seeing this.
