** The monstrous vestige of All For One gives a ''massive'' BreakingSpeech to poor Tomura/Tenko that outlines just what a ManipulativeBastard he really is. ''Everything'' that befell Tenko in his childhood, from Kotaro being an AbusiveParent to Tenko accidentally killing his entire family? ''AllAccordingToPlan'', with All For One engineering an entire TraumaCongaLine [[TheSociopath solely to create someone that runs entirely on hatred and misanthropy]], casually taking away every chance Tenko had for a normal life '''just to carry out a grudge'''. This causes Tomura's vestige to '''''[[DeathOfPersonality shatter]]''''' in despair now knowing that his entire life's misfortunes were just a tool for All For One, leaving his body open for the taking.

* Chapter 290:
** After several years, Dabi finally reveals his true identity: '''Toya Todoroki''', Endeavor's long lost eldest son. And while many saw the reveal coming, it still left a terrifying impression.
*** Dabi washing way the black dye and revealing his naturally white hair, which is implied to be the result of stress from the abuse Endeavour put him through. Coupled with his scarred face, it gives him an almost deathly appearance.
*** More of Dabi's burn scars are shown in his video confession: his entire right arm seems to be covered in burnt flesh, and there is a huge stream-shaped patch in the middle of his abdomen. Almost like someone drew a giant torch over Dabi/Toya's body.
*** Dabi's entire monologue as he gleefully reveals that he had been hounding Endeavor from the shadows this entire time, all the while doing a demented little dance on Gigantomachia's back. He even reveals that he was the one who sent Starservant and Ending after him and laughingly explains that his original plan had been to ''kill Shoto'', his own youngest brother, before their father got bumped up to #1. It truly demonstrates how absolutely ''unhinged'' Dabi truly is. The scene is even more frightening in the English Dub of the anime, thanks to a nightmarish performance from Jason Liebrecht, who truly captures the sheer madness in Dabi's voice.

*** It's especially harrowing from Enji, Rei and Shoto's perspective: a member of your family, whom you know trained to be a hero, comes back to you after years of absence, but he is completely unrecognizable, in the worst way imaginable. Shoto, Enji and Rei's StunnedSilence is a perfect reaction. And as messed up as Enji used to be, he actually [[BreakHisHeartToSaveHim had a good reason to push Toya away]], as using his powers to be a hero would have likely doomed him to an early grave. Instead of a dying heroic son, he got a dying villain hating his own family and ready to drag them to hell with him.
* Chapter 291:
** Though it [[GoryDiscretionShot wasn't originally shown]], Hawks grisly murder of Twice is now on full-display for the reader and the general public in Dabi's pre-recorded confession. This moment is made even more unsettling as [[InstantDeathStab visible blood spills from Twice's wounds]] and mouth the moment Hawks stabs him [[InTheBack in the back of his throat]].

--->'''Dabi:''' Oh man. I didn't expect this. I'm starting to have fun! I wondered "how I could make you suffer? How I could ruin your life?!" Ever since I burned up, ''it's all I thought about!'' As a kid, I didn't know why I existed! I'd cling to Natsuo, bawling my eyes out! But you didn't know that, did you?! At first, when I realized your little puppet Shoto was complete, I figured I'd kill him! But then you unexpectedly became the Number One Hero! ''Who would've guessed, huh?!'' I was suddenly so invested in your happiness! Can you believe in Kyoushu I was actually afraid you were going to die?! I lead Starservant and Ending to your doorstep. Did they make you feel like a big shot? Must have been a heavy burden to achieve your dream after so long. But you were soothed by public adoration, weren't you? Is that why you finally decided to try to bond with your children? Just keep looking towards the future and you could be a better man?! What, nothing to say? ''WELL ALLOW ME!'' The past never dies... '''''YOU WILL REAP EVERYTHING YOU'VE SOWN!''''' Enji Todoroki, let's fall together! Come and dance with me in Hell, won't you?! Well?! '''''SPEAK UP, DAD!'''''

*** Mixed with Tearjerker. Mic starts the chapter [[NoHoldsBarredBeatdown furiously beating]] the unresponsive Kurogiri, screaming that relying [[ItIsDehumanizing this thing]] was a terrible idea from the start and that they should ''put it down'' the second they get back, outright wanting to do it himself. While pretty reasonable considering everything, it's still unsettling seeing Mic intent on killing what's left of his best friend himself rather than risking having his heart torn out again.

** Both Izuku and All For One are knocked back into reality, with the latter now resembling a dessicated zombie who still has Tomura screaming inside of him...until All For One silences what's left of him with another hand on his mouth. Izuku tries to get back up to fight...only for nothing to happen. He looks down in horror to see that ''[[AnArmAndALeg his arms are]]'' '''''[[WhamShot gone]]'''''. The destruction of his arms in Tomura's MentalWorld really did affect him in reality, leaving him helpless while the reincarnated All For One prepares to kill him...[[BigDamnHeroes until the heroes arrive]].
*** It's hard to overstate just how horrifying it is to see Izuku in this condition. Throughout the manga, he's been warned over and over and over that the strain One For All puts on his arm muscles could eventually rob them of all functionality, and even as he's refined his control over that explosive power, Izuku's still done lots of damage to them in his battles...but no one '''ever''' thought they'd basically ''explode'' like this.

* Chapter 418 seems to be built off of a massive HopeSpot for both the characters and the audience, with Izuku finally managing to reach the inner Tenko within and get him calm enough to just talk, with the fingers of Shigaraki's body fading away and giving everyone a chance to sigh in relief ... and then Shigaraki flashes to a memory of his father [[WhamLine that he]] ''[[WhamLine knows]]'' [[WhamLine is not his own.]] And at once, the ground underneath both Izuku and Shigarkai crumbles to reveal the '''giant''' face of All For One, who swallows Shigaraki whole and derides him as a pathetic successor as he grows to near {{Kaiju}} levels of height over the child form of Izuku. The vestige of All For One is still around without Tomura's hatred to push him down ... and Izuku, who was forced to sacrifice the entirety of One For All, is now left to face him alone and powerless.

--> '''AFO''': ''Such a foolish vessel! Losing in a battle of wills to some kid? To this [[InadequateSuccessor absolute nobody]]? Striving for strength, yet invariably weak! Tenko Shimura, you pathetic imbecile ... [[ManipulativeBastard not once in your pitiful life ... has any choice been your own]]!''

** From there, we have a timeskip showing All For One attacking a group of what appears to be mercenaries, growing sharp tendrils from his entire body and stabbing through them all.

** Two months after Yoichi and Kudo escaped, All for One tracked them and the resistance fighters they were with and killed Yoichi when he tried to escape, his anger over seeing his "possession" holding the hand of somebody other than himself causing him to apparently lash out on instinct before he realised what he was doing, blowing Yoichi's body into pieces that then fell into the rushing sewer waters around them, leaving no trace behind of his only family but the bloodstains covering himself and Kudo. Worse still is All For One's reaction. He just....stops completely, sporting a stone faced emotionless expression with a slight smile on his lips, hinted to be simply the way his face defaults to when he's utterly overwhelmed emotionally and cannot externally compose himself. Its clear that Yoichi's death was an ''[[AccidentalMurder accident]]'' in [[ATragedyOfImpulsiveness a moment of pure irrational jealous anger]], one All For One, hitherto TheUnapologetic, actually '''regrets immensely''', but his own stunted emotional maturity merely highlights how monstrous he is at this. Rather than break down or emote in any capacity, All For One simply [[VillainousBSOD freezes]], unable to process or understand what he's feeling at what just happened, so confused by his own natural sorrow and guilt at losing his first "possession", his only family, that he doesn't do anything to stop Kudo's rebel unit fleeing before him. It contrasts against Kudo's own sorrow-filled gaze filled with disgust and loathing at the arch-villain, equally disturbed by his senseless murder as he is, but more capable of natural human empathy and acting on it. The narration even notes that All For One's EmptyEyes are very much this InUniverse, highlighting how they cannot reflect Kudo or anybody else, just like their owner cannot see outside of himself, a solitary monster who's just cut off the only outside connection he ever possessed to another. This absolute confusion and inability to understand that he ''does'' regret Yoichi's death later manifests into All For One's mania with absorbing his brother's Quirk, utterly focused on reclaiming the only remaining piece of him even if he doesn't comprehend ''why'' fully. And to make things even creepier, he kept Yoichi's hand with him as a keepsake, and you finally begin to understand how his obssession with hands was passed on to Tomura.

** The chapter ends on a very ominous note. As if all the destruction, death, and tragedy wasn't bad enough, All For One orders the High End Nomus to free his original body from Tartarus. '''''The Symbol of Evil is going to be free.''''' The fabled Tatarus Prison Break that many fans have anticipated since the end of the Hideout Raid Arc is finally happening... at the ''worst'' possible moment for the heroes. With so many heroes injured, incapacitated, or outright ''dead'', who can possibly stop the High End Nomus from breaking All For One out of Tartarus?
--->'''All For One:''' Why do they assume tomorrow will come for them? No, I won't grant them a moment's rest. Because it's ''my'' turn now. And my turn... will never end. Hear me, my tireless Nomu... it's time to free my real body.

** A brief scene of Tomura's recovery process is partially witnessed and the results... are [[BodyHorror not pretty in the slightest]]. Spinner approaches the darkened cave where Tomura's screaming in agony in their underground hideout, and gets close enough for the light to illuminate what appears to be [[https://static.tvtropes.org/pmwiki/pub/images/finger_horror.jpeg a massive fleshy growth spreading out over the cave walls]] like MeatMoss, its various protrusions resembling fingers. Spinner is shocked speechless at the unnatural sight before the organic horror is sucked back into the darkness, revealing Tomura curled up in agony over his left hand...which is showing the nubs of what appears to be his lost fingers re-growing out of it. This implies that Tomura is overtaxing his [[HealingFactor hyper regeneration]] abilities to forcibly override the one limitation of the Quirk -- that it cannot heal already-lost body parts if the used has lost them prior to gaining the Quirk -- in order to use his Quirk's full potential against Izuku in their rematch. Tomura's one weakness of his advanced Quirk was that he could only use it's most destructive abilities with his un-maimed hand, so seeing him devote such effort into ''forcing'' his Quirks into preforming an action that [[BeyondTheImpossible it shouldn't be able to]], sells how determined Tomura is to win their next fight, no matter the cost. Even beyond the ability of Hyper Regeneration to help hold his body together regardless of what abuse it endures, it's Tomura's sheer willpower that makes him basically unstoppable in a fight, regardless of how he comes out looking in the aftermath.

* Chapter 357: It seems as though Endeavor has finally done and killed All For One in a [[ThereIsNoKillLikeOverkill climatic Prominence Burn]], even confirming that he has no pulse as he clasps his charred corpse in his hands... [[BackFromTheDead then All For One begins talking again]], stating plainly if he really believed he wouldn't have had one last ace up his sleeve in the event of this: '''[[SemanticSuperpower Eri's Rewind]]''', replicated from the Quirk Erasing Bullets stolen from Overhaul, used as a last ditch effort on himself in his dying breath, despite knowing the risk of CessationOfExistence, [[TakingYouWithMe just to spite]] the heroes by giving them [[LastVillainStand an even harder fight]] than they believed as All For One's body begins regenerating back to it's prime before All Might crippled him, with his eyeballs returning to give a frightening DeathGlare coupled with an ear-to-ear SlasherSmile.

** Notably, she seems ''confused'' at first that she's using Uraraka's Quirk before realizing that by imitating how someone uses their Quirk, her ''Transform'' can mimic the Quirk of the person she's transformed into. Toga's turned from just another member of the league to potentially ''the most dangerous of its members

Toga's turned from just another member of the league to potentially ''the most dangerous of its members.''
*** The whole time, however, [[DissonantSerenity Lady Curious is just ''laughing'' as she declares this will be the best headline yet.]]

*** The cracks on Nagant's face that appears as she's blowing up bear a similarity to the cracks left on the 4th's face after he died from One For All "breaking his body." It's unclear if All For One used an additional Quirk inside Nagant or an effect from one of his stockpiled abilities, but if it's the same cause of death, then All For One somehow has the ability to ''induce'' a PhlebotinumOverload in those he grants extra Quirks to, somehow maintaining a connection to the 'loaned' power and being able to push it to the point that it causes the same phenomenon that would have killed the other users of One For All if they hadn't perished at his hands first. The implication is made stronger by the fact that All For One somehow seems to be aware of everything that's happening in Nagant's fight, despite being nowhere near it, implying that [[SinisterSurveillance he can somehow watch and monitor those who have taken extra Quirks from him]] and, if need be, [[YouHaveOutlivedYourUsefulness dispose of them with a thought.]] Accepting AFO's offers of power had always been framed akin to a DealWithTheDevil in the past, and this extra dimension to the [[AnOfferYouCantRefuse control]] it brings him over those who accept just makes the comparison more apt.

* Chapter 320 features Izuku giving Ojiro a particularly wild DeathGlare with his GlowingEyesOfDoom from close up after the latter wrangles him with his tail, the paneling shown from Ojiro's perspective to showcase how menacing and frightening Izuku looks to his friends right now. It's also crossed with Tearjerker, as Izuku is simultaneously expounding why he ''can't'' return to UA, no mater what they say -- AFO ''will'' be coming for him and his dear classmates will be just collateral damage to him in the process of wresting OFA away from Izuku. His frenzied desperation is plainly evident, and the flashbacks to Gran Torino, Aizawa and Bakugo getting maimed and brutalised in front of Izuku by the AFO-possessed Tomura showcases just how bad a toll the knowledge that the heartless Sociopath will be coming for him no matter who gets in his way has taken on Izuku, who is far from being the greatest hero in japan who can defeat him, and little more than a young boy who feels he has no choice ''but'' to face him -- alone -- so nobody else gets hurt, again demonstrating his own inability to consider his own wellbeing before others. The fact that this is still part of AFO's greater plan to grind him down physically and mentally for their rematch sells how outmatched and overwhelmed Izuku is when faced with the task of facing an opponent who is infinitely stronger, more experienced and ruthless than himself -- and moreover, one that no adult can actually protect him from, with AFO's machinations having stripped away the illusion of security and comfort not only from Izuku, but with every other person in Japan right now.

* Todoroki's backstory is, despite the lampshade hung on it to make it not as heavy, pretty horrifying. He's Endeavor's son... and the guy forcefully married Rei, [[DarwinistDesire simply to produce a kid with a Quirk strong enough to use as a tool to surpass All Might]]. After several unsuccessful attempts, Todoroki was finally born with the powers Endeavor desired. By the age of 5, Todoroki was already forced into TrainingFromHell, isolated from others and forced to do nothing but train his powers at the expense of his health. Meanwhile, Endeavor kept abusing Rei, and she was driven to near-madness: one day, she snapped and threw boiling water at her son, giving him his distinctive red scar. Endeavor had her locked away in a mental hospital [[YouHaveOutlivedYourUsefulness as she was no longer needed now that he had the heir he wanted]].

** Also terrifying? Later on, it's revealed that Himiko doesn't just shapeshift into the persons she takes their blood away from. In case the victim is a Quirk user, [[PowerCopying she will gain full access to their Quick]] (explained below), therefore making her even more dangerous.
** Overall, if taking away the fantastical elements from her, Toga is essentially a [[RealismInducedHorror terrifyingly realistic]] and [[AxCrazy extremely violent mass murderer]] who essentially makes her living in grotesquely butchering and brutalizing countless innocents [[ForTheEvulz for shits and giggles]], is [[AffablyEvil eerily polite and calm]] even when [[ColdBloodedTorture torturing]] and inflicting [[CruelAndUnusualDeath slow, painful deaths]] on her victims, constantly evades of the law and overall keeps a [[TheyLookJustLikeEveryoneElse low, everyday profile]] that only give a huge amount of chilling realism to her character in the otherwise mostly fantastical setting of the series.

** Volume Origin gives us a brief glimpse of him in his prime, and it's even worse. He is fighting Nana with... [[EldritchAbomination something...]] We have no idea on what it is or where it came from, it's just some giant thing that is a mess of flesh and features attacking Nana alongside All For One. If that isn't bad enough, after All Might and Gran Torino leave the island the fight was taking place on is outright vaporized. [[NothingIsScarier And none of these get elaborated on, leaving just what they were or what exactly happened unknown.]]

** Mirio usual bright expression is dropped to near rage while fighting Chisaki, who casually admit the above is also frightening. It confirms that Mirio is dealing with a total monster who would do more than harm a child for his own goals.

* Iida gets a new powerup technique, yay! To obtain it, however, he had to ''rip the mufflers of his engines out of his legs'' so new ones can grow. His brother Tensei outright said the process is a super painful but a necessary tradition to get stronger.

* Chapter 266: Hawks takes drastic measures to prevent Twice escaping by ''stabbing him through the neck with one of his sharpened feathers''. Even if it was a moment of last resort on Hawks' part, the efficiency with which he carries out the task is pretty horrific for someone who's job is supposed to be protecting people and inspiring hope.

* Chapter 394 has this one [[https://i.imgur.com/nGfweyf.png symbolic panel]] depicting Ochako as a kid and Toga as an ''horrifying'' HumanoidAbomination that looks like she came straight up from a Creator/JunjiIto work.

* Chapter 408 continues giving us insights on All for One's deprived backstory.

* Chapter 394 has this one [[https://i.imgur.com/nGfweyf.png symbolic panel]] depicting Ochako as a kid and Toga as an ''horrifying'' HumanoidAbomination that looks like she came straight up from a ''Creator/JunjiIto'' work.

** Shigaraki manages to briefly touch Midoriya during their fight. At first it seems to be okay, he failed to dust him... only for Banjo to reveal the horrific twist: Shinomori is no longer inside One for All. '''Shigaraki stole Danger Sense!''' Now, not only does Midoriya needs to fight without the help of one of his most valuable Quirks, but said Quirk is now in his enemy's arsenal, meaning now he can easily predict and dodge his attacks. Shigaraki taunts Midoriya by asking him how much longer he thinks he can last now, and it's something even the audience has to wonder.

** All for One's final end is ''visceral''. With his last ditch attack thwarted, he has been soundly defeated by Bakugo, and yet he still defiantly fires a LastBreathBullet at him even as Rewind has reduced him to an ''infant''. Not only does it fail, Bakugo has to counterattack, giving us the [[SarcasmMode lovely]] image of a literal baby being blasted by explosives. And it doesn't stop there as the inevitable finally happens; [[DeathByDeaging Rewind finally claims his life]], and we're ''not'' spared the imagery of All for One regressing to a newborn, then to a fetus, then to an ''egg cell'', and finally... to nothing. It may be a KarmicDeath for the most depraved villain in the series, but... ''yeesh''.

*** Considering the underground reach of Decay, there is a good chance that Japan will sink and vanish from the face of Earth by the time Shigaraki is done.
