Nightmare Fuel / One Piece

http://static.tvtropes.org/pmwiki/pub/images/hodyface_3298.JPG

Ah, One Piece, a Long Runner filled with exciting adventures that is able to keep up with series such as Naruto and Bleach. Like those two series however, some of those adventures can get you to stay awake and not in a good way.

WARNING: All spoilers for the series in the Super Rookies Era will be unmarked.

    General 
  • Devil Fruit abilities in general can be completely nightmarish, given the right context. Even the most harmless thing you can think of can be turned into a deadly weapon in the right hands. This is especially evident with Paramecia, who have by far the most varied and strange power sets, and often have the most lethal abilities.
  • Happy-go-lucky Chopper on the 3rd Rumble Ball. He turns into a giant mindless, hulking killing machine.
    • Chopper's last conscious thought before he went berserk. "Please don't let anyone enter this room." He knew what was about to happen.
    • At least post-timeskip, he has now learned to preserve his consciousness in said state, but only for a limited time.
  • Slavery:
    • Slaves are forced to do all their master's deeds until they die of exhaustion. If they try to escape, their collars explode. No matter how bad they suffer, they are forced to smile, to show respect to their abusive masters. In fact, slaves don't even have the right to cry!
    • Worse, some owners buy slaves for the sole purpose of making them suffer. Hancock and her sisters were fed Devil Fruits to satisfy their masters' fucked-up curiosity, and one of the nobles who wanted to buy Caimie specifically stated how he was interested to see how long she could out-swim his school of deadly piranhas.
    • What makes it even worse is that even when slaves are freed, they are usually so traumatized and/or physically fucked up that their recovery isn't necessarily assured. The Gorgon sisters and Koala were lucky in this regard, but not all of them were, as a woman in chapter 763 reveals that her daughter came back in such a pitiful state after being saved from slavery that she didn't speak a word, and committed suicide three days later.
  • In general, the lengths to which the World Government is ready to go to "uphold peace" are frightening. For example, when they learned that Roger had a child, they didn't know who the mother was. Their solution was to execute any young or expecting mother who was suspected to be connected to Roger in any way (which failed, because the one young woman who was connected to Roger held her child in her womb for twenty months, specifically to save him from being executed for the mere "crime" of existing). Not to mention they don't even seem to care about upholding peace that much anyway. After all, not only did they cover the escape of many insanely dangerous Level 6 prisoners from Impel Down following Blackbeard's breakout just so they could save face, but they also let the World Nobles (See above) do as they please.
  • The Void Century. The very concept of 100 years simply being erased from the history books is 1984-level nightmare fuel on its own, but there's the idea of what secrets are hiding in that forgotten era of time. Whatever it is, is so bad that even the incredibly corrupt World Government wants to keep it secret.
  • Caesar Clown: the hellish child of The Joker and a Hannya mask, expert of Weapons of Mass Destruction, capable of turning his body into a mass of deadly gas and using his own men as guinea pigs to test his biological weapon all while he plays the good guy's role to them. Now that you know this, think again about all those kidnapped children and let the Fridge Horror in.
    • It gets worse. It's revealed that Caesar was drugging those children by slipping a stimulant drug known as NHC10 on the candies fed to them, to the point where depriving them of it generates not so pleasantresults. Not only does it cause intense pain (The kids were even writhing in agony !), but it also causes the person to go absolutely apeshit, and start attacking everyone at random. Seeing those cute children who begged the Straw Hats to save them suddenly become like drug-craving, bloodthirsty zombies (Complete with Blank White Eyes) is extremely creepy.
      • Lest we forget, we have a healthy amount of Adult Fear and Paranoia Fuel thrown in around chapter 688. Children being kidnapped, fed the above mentioned candies, their parents declared lost at sea, while they supposedly need to be treated for a disease. Otherwise kind and gentle children being given military-grade drugs. Hmmm, bet you wanna take candy at the doctor's office now. Oh, and the kind gentle Master who gave you all this wonderful candy? He plans to put you in a room filled with gas.
    • Oh, and if you happen to have some kind of immunity to his poison gas form? He can just remove the oxygen from the air around you so you suffocate. Sweet dreams!
  • Doflamingo's ability in general manages to make strings scary. Imagine being forced to attack and/or kill people you love, without you being able to do crap about it, as King Riku and Rebecca can attest to (Good thing Luffy was there to stop her in the latter case).
  • The fact that something like the World Government even exists as it does. All the things mentioned about it above, the rampant corruption, their questionable hiring practices, Impel Down... It's like the One Piece world is a place that happened after a The Bad Guy Wins scenario in the distant past, with all the suck it entails.

Super Rookies Era

    East Blue Saga 
Baratie Arc
  • The idea of starving for over a month is a hell that almost anybody shouldn't go through. Sanji and Zeff's starvation is a testament to that. If they didn't live in the One Piece universe, they would've been dead long before a ship would've arrived.

Arlong Park Arc
  • Let's think of the situation that Nami's home island was in every day since Arlong showed up and took over. Everyone has to pay up Arlong's protection money...or his Pirates will KILL EVERYONE in the village. If ONE PERSON fights back, they die. If a person is even caught with one weapon, they die. For every moment since Arlong arrived, the town has had to fear for their lives every waking moment, knowing one wrong move, one thing to tick Arlong off, means you or the entire village will die. The marines are basically helpless because the small name guys who show up are too weak to beat Arlong's men, and the big guys who COULD stop him are being prevented from hearing a word about him thanks to a Dirty Cop on Arlong's payroll. By the time we meet them, the town has given up any hope of beating him. Now remember that Arlong has basically subjected the ENTIRE island to this, and destroyed several villages already.

    Alabasta Saga 
Little Garden Arc
  • Mr. 3's plan to make Zoro, Nami, and Vivi into wax statues, forcing them to suffocate in their prison, is really fucked up.

  • The premise of the island. The island has a set time of 1 year as it takes that much time to adjust it. Not mentioning the extremely hostile life, which hasn't evolved like the rest, which involves dinosaurs and pretty much highly harmful insects. And if you try to leave? The Sea Kings take care of you.

Alabasta Arc
  • Rewind back into Alabasta, and we all remember the lovely scene of Crocodile sucking all the moisture out of Mr. 3. Seeing a human whither into a mummy, as Mr. 0 puts it, is very uncomfortable. Made all the worse when he does the same thing to Luffy.
  • Not to mention Crocodile's systematic breaking of Vivi and the berserker frenzy he whips the rebels and Alabastan army into, to the point that even after everyone is knocked over by a gigantic explosion that would've wiped out everybody if not for Pell's Heroic Sacrifice, they just get right back up with crazed expressions and go right back to fighting.

    Water 7 Saga 
Long Ring Long Land Arc

Enies Lobby Arc
  • The Buster Call. With the push of a single button, entire islands are erased. And not just in the figurative sense either, once The Buster Call is complete, maps around the world are rewritten without the target island. To give you an example of how nightmarish the Buster Call is, Robin, who not only managed to escape her home island's demise at the hands of the Buster Call, but is also one of the most fearless people in the entire story, is completely terrified of the mere possibility of a Buster Call being unleashed.
    • As another hint of how horrifying it is, when Spandam accidentally triggered a Buster Call, the Marines were willing to annihilate Enies Lobby, no questions asked. Even worse, if someone does question it, they are killed.

Post-Enies Lobby Arc

    Thriller Bark Saga 
Thriller Bark Arc
  • We also have the Thriller Bark arc, which featured a gigantic ship shaped like a Haunted Castle that was home to Dr. Hogback, a Mad Scientist who made zombies (including zombiefied, literal Mix-and-Match Critters), Perona, an Elegant Gothic Lolita girl who could summon ghosts that came out of the goddamned walls (and floors and paintings), and Big Bad Gecko Moria, a large, vampire-like man who could steal people's shadows, and briefly traps Luffy's shadow in the body of a humongous zombified giant.
    • The wacky personalities of the various zombies, including Oars (zombified super-giant) act as pretty effective Nightmare Retardant. Because it's hard to be terrified of such very silly creatures... though the method of creating them and the effect of the sun on shadowless people is very Nightmare Fuel-worthy.
  • Perona herself is much less scary than the rest, but still pretty creepy at points. That said, when she fights Usopp, she goes from being charmingly creepy to straight-up scary. For instance, she threatens to crush his heart even if she actually can't. At one point, the look in her eyes just screams "enjoying this more than she has any right to."
  • The scene of Nami taking a bath goes from Fanservice to Fan Disservice when Absalom (who's quite the pervert) comes in and attacks her. Some fans think it looks like a rape scene.
  • Dr. Hogback, who reanimated Cindry's corpse because he 'loved her'. A man with so little respect for the dead that he makes her lick the goddamn floor even when her dead corpse cries from the treatment it is receiving. When Absalom bemoans his lack of a wife the good doctor offers to build him one. Now, let's imagine what he's really been forcing Cindry to do every day for years.
  • The most nightmare-inducing part of the entire arc is, without a doubt, Moria's Villainous Breakdown. His greatest zombie defeated, Moria snaps, ranting about his Freudian Excuse, before entering his One-Winged Angel form in what might be the most terrifying transformation sequence out of this show. And while he's ranting he's got a most terrifying Slasher Smile.
  • Perhaps less than the others, but seeing that... giant thing at the end of the arc. To put it in perspective, Thriller Bark is the size of an island. At the end of the arc, we see this massive creature, easily dwarfing the entire island, merely staring on. It doesn't do anything, but narration hints it's why ships disappear in the Florian Triangle.
  • Even after all the zombies, the scares aren't over. Enter Bartholomew Kuma. Bible toting titan of the Seven Warlords. With the other Straw Hats broken and beaten, he was going to perform clean up. Zoro manages to plead that he be taken instead of Luffy. Kuma agrees, but not before laying down the line to just the right music.
    Kuma: But before you can take his place, I will make you experience Hell.
    • He wasn't exaggerating. He extracts all the pain and fatigue from Luffy, which is manifested as a red bubble as big as Kuma, and puts it into Zoro. To elaborate, when one tiny little baseball sized blob of the pain bubble was pushed into Zoro, he reacted in sheer agony as if a bomb just went off in his chest, coughing up blood. The anime makes it even worse by having Zoro screaming in agony.
  • For that matter, having your shadow stolen. Just imagine constantly having to flee sunlight like a vampire, lest you will be burned to a crisp. As Brook tells the Straw Hats, he witnessed firsthand one of Gecko Moria's victims going crazy from having his shadow stolen, then running into sunlight, which quickly immolated him to ashes in an extremely graphic manner.

    Summit War Saga 
Sabaody Archipelago Arc
  • The Celestial Dragons. They have a complete and absolute disregard for human life, and are utterly untouchable. They also get even more repulsive each time they're brought up, as you learn more about what horrible things they do.
    • As a testament to how unstoppable they are, Monkey D. Luffy punched one in the face, causing Kizaru, Sentomaru, and Kuma to fight the Straw Hats. Luffy and his crew were decimated.
  • The fight with Kuma is Grade A Nightmare Fuel and Tear Jerker fuel. Luffy has to watch all his friends slowly (as far as he can tell) die one by one, and all he can do is scream, begging them not to fight back and just RUN so they have a chance of meeting again, all while their killer has no expression as he does the deed and completely makes them vanishes by just a touch of his hand. Some of them cry out, begging Luffy for help as he stands there completely powerless against Kuma. Finally, he comes to a broken and bawling Luffy and he vanishes too. Absolutely ruthless.

Amazon Lily Arc
  • The Hancock sister's backstory as slaves of the Celestial Dragons. We (thankfully) see very little, but judging by how they'd all die rather than having it seen and risk to be recaptured by the Dragons, it wasn't pretty. Sandersonia in particular has a panic attack just by hearing Boa's recounting of those events.

Impel Down Arc
  • The Blugoris from Impel Down are freaky. Large, vaguely humanoid creatures wielding giant battle-axes... with no face. Just a small lump for a head and what appears to be a painted-on skull (though the anime establishes it as more of a hood).
  • Impel Down itself. All prisoners are first boiled alive upon being sent there, and part of the punishments involve walking upon a field of razor sharp blades until your feet are nothing more than shreds. The kicker is that this occurs on the first level. The tortures get progressively worse as you continue further deep into what other characters in the manga have explicitly referred to as 'hell on earth'.
    • Level 2 is full of wild beasts that are kept in the prison because if they were allowed to roam free, they would eat people.
    • Level 3 is blisteringly hot, and food and drink is restricted. And the piles of sand everywhere? That's actually the remains of prisoners' bones after they've died and withered away.
    • And the reason Level 3 is so hot? Because Level 4 is home to a gigantic cooking pot full of blood, in which prisoners are boiled alive as torture. Level 3 is used as a vent, so Level 4 is even hotter.
    • Level 5, for contrast, is kept at freezing temperatures. Prisoners can get frostbite, if they're lucky. Unlucky prisoners, on the other hand, might meet the wolves that roam the level. They're kept down there, because they would eat the man-eating monsters kept on Level 2.
    • And Level 6? They simply leave you down there until you fade from acknowledgment. Even the level itself is not publicly known to exist.
  • Magellan's devil fruit. Despite being a somewhat outstanding guy, there's a lot to be afraid of a man made out of pure poison.
    • And then we get the oh so lovely image of Luffy covered in poisoned goop, with face frozen in an expression of agony and horror, like he's screaming. Sweet dreams.
      • As if that isn't bad enough, Ivankov's treatment for it is even worse. Imagine everyone's favorite doofy pirate captain screaming nonstop in agony for two straight days as his body breaks down and regenerates. The fact that he got over it in less than a day is definitely a mercy.
    • Magellan's Venom Demon is a skeletal-looking beast that dissolves almost anything it touches. It's as scary as it sounds.

Marineford Arc
  • How about in the Marineford arc when Akainu friggin' BLOWS OFF HALF OF WHITEBEARD'S FACE?!
    • Heck, Akainu in general, especially after he recovers from Whitebeard's beatdown and proceeds to chase after Luffy. The man's a damn tank and nothing is going to stand in his way. Not even the toughest pirates of the One Piece world.
  • Also in the Marineford arc, in the anime, we're treated to a shot of three Pacifista slowly walking towards the camera, with their faces silhouetted, aside from their glowing eyes. In the background we've got what looks like a large fire illuminating the Pacifista. It's pretty unnerving.

The New World Era

    Fishman Island Saga 
Return to Sabaody Arc
  • Caribou. Just Caribou. He is a psychotic homicidal lunatic who prays to God to forgive his victims of their sins.
    • His swamp Logia powers are really grotesque looking, too. He looks like a puddle of melted flesh, although this can be attributed to being black and white and Oda's art style.
    • Also, the way he was kidnapping those mermaids eerily resembled a rapist assaulting his victim.

Fishman Island Arc
  • Hody Jones in general. He's basically One Piece's response to Adolf Hitler... or at least, Hitler if he had been stopped before he could have achieved his dreams of conquering his own country...
    • Hody Jones' latest form can be this, with that huge, gaping murloc-like jaw. The anime cranks his Energy Steroid usage Up to Eleven by giving him blood-red eyes when he does so.
      • If it's any consolation, he doesn't get a chance to do anything other than receive a truly incredible No-Holds-Barred Beatdown from Luffy, which he definitely had coming. But when he's rendered immobile, his eyes start jittering around as his body wigs out to the steroid overuse. There's a reason why this is the page image.
  • Cruel to be kind though it was, Koala's scream and the hiss of her burning flesh when she gets rebranded still belongs here.
    • Not to mention the blank, terrified look upon waking up, still smiling. The kind of trauma she had to go through to ingrain that on her on threat of death must have been unimaginable.
  • Hyouzou earned his place here by being a blood-drunk kind of Drunken Master. It's one thing when you're the strongest swordsmen among the Fishmen with Combat Tentacles that lets you wield up to six swords in one go. That's textbook badass. But throw in a hopeless addiction to alcohol that completely robs him of his sense of judgement and you have a the equivalent of a runaway lawnmower on your hands. He's twisted into an uncontrollable monster who julliennes the hell out of anything he sees, even his own allies! When the enemy is running away from one of its own powerhouses, you know shit is about to hit the fan.
  • The price of using the Energy Steroids is ghastly. Your body rapidly ages until you are old and frail, and your lifespan drains dry. This happens to all of the Neo Fishman Pirates executives, especially Hody Jones, who used so many more than his peers that he's now a veritable fossil hunched over and forced to use a cane. Also of note was that when he and Hyouzou took especially large doses of the steroids, their hair went white long before their bodies shriveled up.
  • We now have a first full look of Big Mom. The anime adds blood-red eyes to her, just like Hody, which somehow manages to make her even more terrifying. Yeesh.

    Dressrosa Saga 
Punk Hazard Arc
  • The guys in Chapter 656 who kidnapped the remaining Straw Hats look pretty creepy with those diving suits.
    • Wait, there's more: brought to an island half on fire, half frozen, in a nursery-like room full of giant children. There's also the question of "what exactly 'divided' that samurai like that?", which doesn't get an answer until Law is reintroduced.
  • Two words: frozen corpses.
  • We find out that Trafalgar Law was able to join the Seven Warlords of the Sea by sending 100 pirates hearts to the government. Knowing what the government would and could do with those hearts, what do you think has happened to those pirates?
    • Him doing it to the Straw Hats, is actually presented as a comic moment, since it results in a "Freaky Friday" Flip. But then he pulls off a different procedure to Smoker; we see his actual heart. Not so funny.
  • A bit which could also fit into Fridge Horror is that (be careful, triple spoiler ahead) the 100 pirates who got their hearts stolen by Law are definitely not dead, as Tashigi was perfectly OK in Smoker's body despite the fact that Law had stolen Smoker's heart.
    • Speaking of Fridge Horror, Caesar Clown is an "insane bastard" (Smoker's words) whose primary field of expertise as a Mad Scientist is mass-murder weapons. And he holds kids captive inside his main facility. The question "Just what the fuck does he intend to do with them ?!" is guaranteed to stay in your mind until later chapters reveal why he does so: to transform them into giant human weapons, which he does little by little via repeated experiments on them. Worse, he slips a deadly drug called NHC10 into the candies he feeds them to keep them in check. Withdrawal from the stuff causes the kids to experience severe pain and go into an Unstoppable Rage, basically turning them into candy-craving zombies. Eating too much of the stuff like Mocha did to protect her friends leads to excruciating agony, Blood from the Mouth, and near-death (Good thing Chopper was there to stabilize her condition). That's not even the end of it: Caesar gloats about the fact that his young guinea pigs will be dead in five years if this keeps on going, saying he'll have to get replacements. This is one frighteningly repulsive man.
  • Related to the above, chapter 675 shows us how Mocha snapped back to her senses, which doubles as a Tear Jerker: with a very creepy set of hallucinations terrifies her, and her memories of Usopp and Nami trying to snap the children back to their senses makes her scream for Nami and Usopp's help and apologize for not listening to them earlier. And because it bears repeating, this terrifying withdrawal episode happened to a child.
  • The Blob Monster Slime released by Clown in chapter 668 isn't a pleasant sight.
    • It's not just its looks that are monstrous, it's also basically invincible. It constantly releases poisonous gas, so you can't get too close without a mask, and cutting or shooting it just makes it spew out more. Plus, if you touch it, you are instantly infected with its poison, and the effects aren't pretty. So, if you can't attack it with weapons, or even attack at all, what's left? How about fire? Nearly all creatures fear fire, so let's try torching this one. But wait, this thing's made up of gas, so it'll just explode if set aflame. And even though it's not good with water, the poison that it spills in still works. And then it shows off its Devil Fruit ability.
    • And things just got even worse: after eating a bait made by Caesar, it changed into a huge cloud of gas that petrifies its victims fast as shit. Bonus points for how scary the statues look and the guy begging for help as he's being petrified.
      • AND IT GETS WORSE... Caesar mentions that apart from the petrification, it's the same gas as before; that is, it cripples, but the victims live long enough to crawl away when they had no legs. Fridge horror ensues since the gas must take hours to actually be deadly, but now paralyses instantly, effectively meaning that the victims merely die of suffocation a minute or so after getting paralysed. Of course, if the ash is porous, which may well be the case considering it's supposed to be an improvement of the same gas weapon, then they simply stay petrified for a long time becoming increasingly poisoned before it eventually kills them. So the only immediate effect is to petrify alive.
  • Monet's monster form is actually pretty frightening. Seeing the Cute Monster Girl grow a giant set of teeth capable of biting off a Marine's shoulder. Brrr.
    • Later on, Zoro cuts her in half vertically. She survives, but that was only because Zoro decided not use Haki. Because Monet is too scared of what Zoro could have done to her, she is unable to put her body back together right away. Seeing her two halves moving about erratically, melting into snow and getting back into shape time and time again, is disturbing as hell. The look of absolute rage on her face(s) is not a pretty sight either, and gets even scarier when you compare it to how calm and cute she looked before.
    • There's also her ability to weaken someone by embracing them. You have to remember that Monet is a snow woman, and falling asleep in the snow can effectively kill them. Monet does something similar, by weakening an opponent with the cold she exudes and causing them to fall asleep. The fuel doesn't end there though. When she used it on Luffy, she described that his heart would freeze and he would die in his sleep. So Monet basically kills someone with Hypothermia. Urrggh...

Dressrosa Arc
  • You see the toys in Dressrosa? They used to be human. Not only that, but everyone, even those closest to them, forgot they existed in the first place. Worse yet, they can't report on it, because if toys even try to step in a human's house or talk to them too closely, they get declared "broken" and thrown into the scrap bin. That is already scary and sad enough, but to top it off, some of these toys have been in this situation for ten years.
  • It sort of takes a lot of the excitement out of the Tournament Arc that's happening in the Corrida Colosseum when it's revealed that the losers are dropped through a Trap Door into a dark pit where they wait to be turned into toys.
    • Speaking of taking out the excitement... the entire tournament is shown to be for nought for nearly all the participants given that with said transformation everyone will proceed to lose memories of these humans-turned-toys and consequently the tournament they took part in.
    • There's also an uncomfortable bit of Fridge Horror: What happened to the broken toys in the scrap heap? Did they turn back, and if they did, in what shape? It's made even worse by the fact that no one mentions it, meaning they possibly stayed transformed if they were dead, or that they didn't manage to escape the scrap heap yet.
  • Doflamingo puppeteering King Riku into killing his own people against his will. His Slasher Smile framed in shadow does not help matters.
  • Usopp's face and his scream on the last page of Chapter 742 qualifies. It was so bad, it caused Sugar to pass out from the scare! To some, it would probably be a Nightmare Retardant because of how exaggerated it is, and because Usopp is generally known for his ridiculous wild takes, but a such detailed and distorted face actually looks like something Junji Ito could have drawn in a less comedic context...
  • The Birdcage. Doflamingo traps all of Dressrosa in a literal birdcage made from his threads. Said cage hurts anyone who tries to leave and cuts off all communication with the outer world. Law then says Doflamingo intends to kill all of Dressrosa before the truth about the country leaks. And Doflamingo says that what will follow will be worse than the time he puppeteered King Riku into killing his own people. Doflamingo reveals he can control anyone he wants that's trapped inside the cage, says he could have ruled over Dressrosa with terror from the start if he wanted to and starts a hunting game where you either kill him to get out of Dressrosa, or kill the people he designates. And the "Holy Shit!" Quotient breaks again.
  • Chapter 760: We're finally given a hint of what Doflamingo's youth was like. He was a Spoiled Brat who couldn't appreciate why his father insisted that they abandon the rank of Tenryubito and live among their subjects. The few flashbacks we get show young Doflamingo brazenly asking where all the slaves are, angrily demanding to borrow his father's gun so he can shoot a "lowly commoner" who "dared talk back to him," and stubbornly blaming his father for his mother's death because he moved them to "this filthy outside world." And after his mother's death, he kills his father, and tries to make the World Nobles take him back into their community by presenting them with his father's severed head. When they refused this offer, saying that he and his family were traitors that could never come back to the holy land, he decided that he'd retaliate by throwing the world into chaos however he could in what amounts to a terrifying, decades-long temper tantrum.
  • What happened to the White City, just... everything that happened. Especially when you realise lead poisoning of that level DOES EXIST! (albeit it's very rare now due to modern medicine)
    • The truly frightening part is the very likely inspiration: Asbestos, a highly profitable mineral that was once used all around the world, and can be found in all kinds of goods, but use of asbestos was discontinued when it was discovered to cause serious and even fatal diseases. And much like in the case of the Amber Lead, many governments initially ignored the scientific and medical reports about asbestos' toxicity, continuing to allow its use into the 1980s, while the ill effects were demonstrated since the 1890s. In fact, the Amber Lead Poisoning has a real life equivalent with asbestos, mesothelioma. Even the country of Flevance may be based off a town whom thousands of people died from mesothelimoa via asbestos, Casale Monferrato.
      • It also mirrored "itai-itai byou" or the 'it hurts, it hurts, disease." It was due to cadmium poisoning, a result of Japan's industrialization in the early 20th century. Their growing need for cadmium led to improper mining and water being contaminated. The same water was used to irrigate rice fields so the cadmium accumulated in people.
    • Oh, it gets worse. Amber Lead poisoning isn't contagious, but that didn't stop people from thinking it was. They closed off the country and shot anyone who tried to leave. Eventually they just killed everyone in the town. So how did Law escape? He hid in a pile of corpses. Keep in mind he was about ten at the time. No wonder the guy is so messed up now.
  • Chapter 763: Doflamingo's real origin story. Once Doflamingo's family left Marejois, it didn't take long for the people of the island they set up their new home on to find out they were former Celestial Dragons, especially with Doflamingo spouting it out to everyone. Many of the citizens turned out to be victims of the Celestial Dragons' cruelty, and since the Doflamingo family wasn't a part of them anymore and the island wasn't a part of the World Government, things went to hell quickly. The Doflamingo family had to go on the run after their mansion was burned down, moving from place to place in squalor, the strain of which eventually lead to Doflamingo's mother dying of sickness brought about by exhaustion and their horrible living conditions. All the while, Doflamingo's father tried to plead with the Celestial Dragons to let his wife and children back into Marejois, and eventually just his children once his wife had passed, but the Celestial Dragons refused all the same. Eventually the mob ended up finding them, and ended up torturing them, even when Doflamingo's father begged them to take out their anger just on him instead of his children. Small wonder Doflamingo still has nightmares about it as an adult.
    • This chapter also provides even more evidence of just how monstrous the Celestial Dragons really are on the whole. Even setting aside their blatant refusal to even accept Doflamingo and his brother back into Marejois, despite it being their father who made the decision to leave and them being in desperate peril, the stories the mob hunting the Donquixote family have of their experiences with the Celestial Dragons are downright bone-chilling. One man tells of how his two sons, five and two years old, were killed by being shot SIXTEEN TIMES just for crossing the path of a Celestial Dragon in the street. A woman tells of how her daughter had been taken up as a plaything by the Celestial Dragons, and as a result of whatever horrors were inflicted upon her, she came back home a disfigured mute who committed suicide three days later. A former slave tells of how the Celestial Dragons plucked out his eyes for entertainment while a man mentions how they burned his wife alive. And to top it all off, their demands of extravagant tributes from citizens has led to countless people starving to death. It doesn't excuse their hunting down and torturing of Doflamingo's family, but it's easy to see why they'd have such a seething hatred for ANY World Nobles.
  • Chapter 764 reveals that, to Corazon, the scariest part of that night wasn't the torture he endured. It was seeing his own brother seething with hatred and vowing to kill everyone in revenge. Corazon wonders how his kind-hearted parents raised such a monster.
  • A chilling detail regarding Corazon's death: in order to protect Law from Doflamingo, rather than erecting a bubble to cancel noises within a certain range, he chose to silence Law himself, muffling any noises He produced and reducing the chance of his discovery by the Donquixote Family to zero as long as he remained still. While it ultimately saved his life it also meant that Law could clearly hear the Donquixote Family beating Corazon for his treason, Doflamingo's horrifying intent to hunt Law down to the ends of the earth to brainwash him into Undying Loyalty, and no matter how hard he screamed and tried to break out, he was unable to muffle the sounds of Doflamingo emptying his gun into Corazon and the sound of his body hitting the trunk he'd locked Law into.
    • Corazon's last moments are pretty heavy in Adult Fear: he KNEW he was at the end of the line yet desesperately stayed alive as long as possible, because if he had died too soon, Doflamingo would have heard Law crying and be able to capture and brainwash him until he would have accepted to DIE. Remember, Law was a 13 years old at the time.
  • Chapter 771: After Baby 5 mistakes Sai's words for him hitting on her and Sai jokingly tells her she can be useful to him by killing herself, Baby 5 takes this seriously and happily turns her arm into a gun and aims it at her head. After learning that her mother abandoned her for being useless and tells her that no one needs her, the fact that Baby 5 is willing to go this far to be useful to someone and be completely happy about it is quite disturbing. And despite being enemies, Sai was disturbed by this so he stopped her from killing herself.
  • Chapter 772: Dellinger gives in to his Fighting Fish heritage and goes full Blood Knight on Ideo. It's the shots of his face spattered with blood and a sharp toothed psychotic smile that seal the deal.
    • When he transforms, his human teeth all fall out to make room for his shark teeth.
    • Here's a picture of it, if you're wondering.
  • Chapter 781: The Birdcage starts shrinking. It's bad enough that it's basically a razor wire fence that will shred you to ribbons if you so much as touch it, but now it's actively chasing everyone inside, Advancing Wall of Doom style, and in an hour, it will collapse to nothing, dicing anyone who's survived that long into finely-shredded chunks of meat. Yikes.
  • Chapter 782: The rest of Doflamingo's backstory is revealed: When he was 10, not long after he escaped his torture with Haki, it is revealed that his executives were originally just 4 dudes who picked him up and decided to raise him up. With the knowledge that he has the Conqueror's Haki, they instantly decided to help him with revenge and payback, even bowing to him. And thus, a Psycho-Jerkass was grown and raised. And the worst thing is, anyone could have turned out that way in these circumstances.
  • Chapter 783: Doflamingo describes in greater detail the fact that his Birdcage is shrinking. Within 30 minutes, people will probably start dying; and wondering who will the be the first to go: the elderly, who probably won't know what's coming until it's too late? The children and babies, who can't escape properly? Within 40 minutes, there will be loads of shouting and screaming. Within 50 minutes, the entire country will be squashed like a tomato and soaked in red. After an hour, "there will be no more sound being made from those pesky humans". This guy is fucking insane.
  • Chapter 795: "Suicide". Imagine if you will: a man who has been captured eighteen times, subjected to ten thousand different means of torture and still lived. Forty death sentences, all of which meant nothing. When hung, the rope snapped. When put to the guillotine, the blade was shattered. When accosted by spears, they were snapped with ease. A man who has been so desensitized to his own deathless nature, this invulnerable giant, this monster finds it amusing to walk off the edge of Sky Island and plunge headfirst into the earth, thousands of feet below, just to see if it does anything. This man is the Yonko Kaido, and now you know why the entire world fears him.

    Yonko Saga 
Zou Arc
  • As the Straw Hats venture through Zou, the sight of wooden crosses covered in blood are seen several times. We then learn that Jack and his crew showed up looking for Raizo the ninja. The minks have no idea who that is and tell them, several times. A leader of the village even offers to allow Jack's crew to search for Raizo as thoroughly as they wish to prove the minks aren't lying. Jack's crew ignore him and just declares they're going to rampage.
    • Worse, the rampage wasn't what destroyed everything as the Minks did manage to fight back fairly well. Jack brought in Caesar's gas weapon to destroy everything.
  • Chapter 810: We see the aftermath of Jack's massacre. Several Minks were crucified, injured ones were slaughtered. Dogstorm lost a leg, and Cat Viper lost an arm. All shown in gory detail.
  • Zunisha, the colossal elephant on whose back Zou is situated, is amazing for the simple concept of an ancient creature so huge, it carries an entire island and a civilization on its back, but has also some really creepy elements. First, it looks like it has no eyes: they are so small and hollow, the socket seem empty. Secondly, you have to wonder how absurdly and disproportionately long its legs must be, since they must reach the bottom of the sea. Apparently its design is inspired by similarly grotesque elephants in a painting by Salvador Dalì, whose works may well qualify as Nightmare Fuel for many, so no wonder. Finally, one should ask what may happen if Zunisha went out of control for any reason...
    • As Chapter 821 showed, Zunisha is not simply a giant elephant carrying an island, but a sentient being. Thankfully it is a benevolent being who doesn't mind carrying an island on its back and will only go on the offense when commanded to by someone who can hear the voice of all things. However, that doesn't mean one should provoke it into asking for someone to give it the attack command. Zunisha shows just how immensely powerful it is when it obliterated Jack's Fleet and Jack himself with just one swing of its trunk.
  • Chapter 815 reveals why Sanji's invitation to Big Mom's tea party is an offer he couldn't refuse: If he had, Big Mom would have killed one of his friends and sent him their head. It could have been one of the Straw Hats, someone from the Baratie, or even someone from the Kamabakka Kingdom. Big Mom has so much power that she can find out everything about her targets' loved ones, and use them as leverage against them. Yonkos have so much power that their demands become inevitable fate...
  • Chapter 817 reveals that Momonosuke and Kin'emon aren't actually father and son. Chapters 818 and 819 reveal that Momonosuke's real parents were executed by Kaido, and that Momo had to witness at least his mother getting killed.

Totto Land Arc
  • Chapter 827 gives us our first real good look at Big Mom and her many Disney-esque servants. Bright colors, singing, out of context it looks happy. But when you consider Big Mom's Establishing Character Moment was eating one of her own crew, has a history of decimating islands if they don't deliver her sweets, and will murder a loved one if you don't accept her Tea Party invitation, and in the scene itself, her declaring she doesn't care whether the jam is the usual stuff or made out of human blood, makes it quite creepy. Said scene is also coupled with small scenes of her troops murdering people in other countries to gather cake ingredients.
    • Another thing that's creepy about that chapter is Big Mom's dream is to gather all the races together. Now given the aforementioned jam and her eating her own crewmate because she was hungry, what do think she's going to do with all of them?note 
    • What makes her dream of racial equality Nightmare Fuel is that it's coming from a Big Eater. If it came from anyone else, it would've been a noble goal. The implications of this are frightening, to say the least.
    • The anime manages to make it even creepier due to the carnivalesque music and the incredibly disturbing visuals coupled with Big Mom's Nightmare Face. They also used the animator who likes to go for a messier look to the characters and give them more rubbery motions, adding to the surreal terror.
    • Charlotte Muscato runs away in a blind panic at the sight of his swirly-eyed nightmare mother is chilling enough. Watching Charlotte Muscato's eyes roll back in his head as he grasps for the last ounces of his soul, then witnessing how everything goes dark around him as he falls down dead, pale and lifeless? You'll need to hug somebody good and tight afterward.
  • Chapter 829 gives us our first good look at Big Mom in action and establishes her character: an Ax-Crazy glutton who will murder anyone, up to and including her own children, if she doesn't get the food that she wants the moment she wants it. And, to make matters worse, she has the power to steal souls with a few words and a simple touch. Basically, in the span of one chapter, the previously enigmatic Big Mom has established herself as one of the most dangerous and terrifying characters in the entire series. In what could be the most "sugary" arc in the story yet!
    • Fridge Horror bonus: Big Mom had many children by many different husbands. Just think about that for a second, the husbands had to make babies... with her. And then there's imagining what it's like for the children themselves (raised by an insanely strict parent who could get a craving at any moment and kill you just for getting in her way). It really rings true for those with Abusive Parents or otherwise mentally unstable ones.
    • That's worse? We later find out that Big Mom sincerely has no control over herself during these 'Hunger Rages'. Meaning even if she were aware her son was begging her to stop and wanted to spare him, she physically can't. When her children say nothing will stop her except getting the food she's craving, they're right. She literally cannot snap out of her rampages any other way.
  • Chapter 831: The idea of having a place called the "Seducing Woods" in and by itself. The fact that there's dangerous creatures that can "think" is bad enough, but the whole forest going out of the way to keep the Sanji Retrieval Team (sans Pedro and Brook) confused and lost is worse. Bonus points go to the forest as the trees hide the skeletons of the poor souls who had wandered there before.
    • Fridge Horror in how they got their name in the first place: the entire forest is made of candy! No wonder the Sanji Retrieval Team got horribly lost!
    • The whole place can be compared to that infamous forest scene in Snow White and the Seven Dwarfs, with a sugary coat of cuteness and talking animals and plants just to hide how fucking terrifying it is. The moment you enter, it's a never-ending walk with no exit in sight, and the trees and shrubbery you thought were totally non-sentient? They can think, and they know where you are...
  • Chapter 833: There are some specific moments in this chapter:
    • Sanji's past. He was abused heavily not just by his father but by all of his siblings. His father even locked him away and placed an iron mask on him for cooking food for a few commoners. His treatment was so bad that he ran away from home to East Blue. While still a child.
      • Mixing in with Fridge Horror, the revelation of Sanji's connections suddenly makes it seem that having a Doppelgänger was actually a good thing. The existence of Duval ensured that Sanji would be able to stay out of his family's radar and out of his father's reach for a number of years. Now it no longer applies since Sanji fixed Duval's face. Imagine if Judge managed to find Sanji before his Sabaody Arc development happened...
    • The Germa 66 mindset. Every soldier has been thoroughly conditioned to follow their superiors' every order, even if it costed their lives. We get to see that first with Sanji's eldest brother, who says "Wall" in response to being threatened by a soldier on Broccoli Island, and one of his men actually jumped and took the bullet meant for him! A few chapters later, during the fight between Sanji and his father Judge, Judge calls out for a wall, and then stabs one of the men to get an advantage over Sanji!
    • After their duel, Sanji has bracelets placed on him. Sounds like nothing... until Judge reveals that the bracelets are like the collars that the slaves belonging to the World Nobles wear and will explode if Sanji tries to leave!
  • There's a reason everything in Totto Land is alive. Big Mom ate the Soul-Soul fruit, allowing her to manipulate people's life spans, and every six months she takes a month off of the citizens of Totto Land to bring other things to life. In other words, she's slowly killing her own subjects! Even worse, she takes the life force from those who answer "Life" when asked "Life or Leave"? What's the consequences for answering "Leave"? A later chapter reveals the answer: you DON'T, because Big Mom WILL kill you and kill anyone connected to you!
    • Not only are Nami and the others completely overwhelmed by Brulee and her forces, but they learn they've been observed since first arriving on Whole Cake Island. The Straw Hats are beginning to see the true power of the New World.
  • Big Mom keeps eating all the food Homies alive. Some of them beg and scream for their lives, while others resign to their fate.
  • When Charlotte Cracker bursts into the Seducing Woods, he literally scares the life out of the forest Homies with blast waves of pure malice. The anime makes it so much worse- we see them withering and crumbling and melting and turning all pale and sickly and hollowed out mouths and eye sockets where their faces used to be and then a panning shot of heaps of dead Homies and OH HOLY MOTHER THE SCENERY IS A BYPRODUCT OF HELL. Showing death to anthromorped objects in a show that young teens watch. Smooth as stalactites...
    • And then the carnage continues as Cracker kills Homies simply by running past them and, several times, he stomps over and smashes the lifeless vessels of the dead Homie trees. He becomes a Walking Wasteland after passing through the Seducing Woods while giving chase to Luffy.
  • Chapter 839: While trying to find Niji, Sanji is led into a room chock full of People Jars, containing Germa 66 soldiers. Although we don't know who or what these soldiers are or are going through at that point, Sanji is quite understandably shocked.
  • Chapter 845:
    • There's something really disturbing with having foods that are sentient and constantly singing how wonderful they taste for lunch. Sanji is understandably freaked out.
      • That also adds more disturbing aspects to Big Mom's character. How twisted is she to use her powers to bring food to life when she plans to eat it? Horrifying concept, huh?
      • When Yonji eats a pancake, it screams in pain at first... before asking him if he finds its taste pleasing to his palette. His only comment is how excessively loud his "meals" are. Brr...
    • This chapter shows more twisted members of the Charlotte Family by introducing a small girl called Charlotte Anana who tattles on the Head Chef because she wants the chef's knives so that she can stab her plush toy with. The worst part? Big Mom doesn't mind that even when some of the other members of her family ask her not to encourage this behavior by off-handedly saying that everyone has 100 to 200 people they want dead and accept the idea as a fact.
      • Another one of Big Mom's children wishes to kill Anana for being "rotten to the core", and Big Mom doesn't mind that, either. Anana may not be a saint, but that's just disturbing to hear coming from a child's mouth.
  • Chapter 846:
    • Charlotte Smoothie's Devil Fruit power. She is able to somehow actually drain a person of some sort of "juice" or liquid of some sort, and drinks it. The poor victim is left shriveled up and left on the floor, twitching and obviously still alive.
    • Amande slowly, painfully bisecting King Baum with her sword, even telling the tree she's doing it just to make him suffer.
    • Mont-d'Or's twisted Book World traps Luffy in an illusion full of bizarre and even somewhat disturbing images and physics. Mont-d'Or's shadowed face burning into the Book World is quite creepy in itself.
  • Chapter 847: Mont-d'Or's Book World ability is used to help Big Mom collect exotic humans and animals and preserve them by trapping them in books where they will never age or escape for eternity. These people are able to speak, and are totally conscious and aware of their situation. And what's worse, they're pinned down with the same kind of pins you'd see in butterfly or insect collections. Even the Vinsmoke family is (understandably) freaked out.
  • Chapter 849: Reiju reappears, and she's received a No-Holds-Barred Beatdown from an unknown assailant.
  • Chapter 850: Holy shit: Pudding is revealed to be the three eyed girl. Normally that wouldn't be a problem, but she's also revealed to have been evil all along and is one of Big Mom's most trusted children who was playing a long con with the Straw Hats and Sanji, She gleefully exclaims to a tortured and restrained Reiju that she's going to murder all of the Vinsmokes. And the reason she freaked Nami and Luffy out earlier? She told them her plans, and that they're going to die too. And there's also the matter of that horrific Slasher Smile she flashes Reiju... *shudder*
    • A flash back is shown revealing the gruesome incident where Pedro lost 50 years of his life and his left eye- which was not in battle as one would be led to think it was. Big Mom was going to punish him for trying to steal her Poneglyphs and putting out Tamago's left eye, so she made his crewmate Zepo spin her wheel of death and it landed on 100 years. Zepo had only 30 years left in the tank, so he died. (If Zepo happens to be Bepo's father, then it takes on a whole new meaning of tragedy.) Then, Big Mom didn't even give Pedro a chance to mourn and immediately resolved to yank the unpaid 70 years out of him. Pekoms bawled buckets before Big Mom and that was only enough to make her shave a decade off the sentence. In response to this, Pedro literally paid back an eye for an eye and TORE HIS OWN EYEBALL FRESH OUT OF HIS SOCKET AS A PEACE OFFERING. What makes this so horrifying is that Oda shows the bloody eyeball in full to portray this moment, and Oda rarely takes the blood and gore to such an extreme like this. Moreover, even though he gave up an eye, Big Mom took just another decade off the sentence and Pedro had 50 years of his existence taken away (if an eye is just worth a decade, then what does it take to make her round off even more- total blindness and quadruple amputation!?!). Even after this incident, Pedro has become all the more uncaring about what happens to him and his remaining life, intending to fall here at Totto Land if need be.
  • Chapter 851:
    • Pudding is the user of the Mem Mem Fruit (as in memory) and she can manipulate the memories of anyone she gets her hands on. She uses it to ensure that no one can remember her true nature, leading to many dark thoughts on what she could (and probably, has) done with this power.
    • Opera's calm demeanor as he escalates from using torture devices on Nami to preparing a crossbow to shoot at her until she reveals Lola's location.
  • Chapter 852: The reveal that Vinsmokes Ichiji, Niji, and Yonji were programmed from birth by Judge to become remorseless killers; Judge thought Virtue Is Weakness, so he made his sons literally and psychologically incapable of feeling empathy, resulting in them becoming complete assholes. Sanji was originally intended to be like his brothers, but his mother Sora basically poisoned herself with a dangerous drug in hopes of saving her quadruplet sons from their father's plans. Out of the four of them, however, only Sanji came out successful. It casts a chilling light on the Vinsmoke children's pasts, largely because of the many ways the Lineage Factor can be altered in both body and mind, and the things Judge was willing to do to fulfill his own ambitions of world conquest.
    • Mixed with Tear Jerker, the pure Adult Fear Vinsmoke Sora went through when Judge decided to genetically alter her children is nightmare-inducing, too. She had the sheer misfortune of marrying an Evilutionary Biologist who also happened to be a warmongering king who believes in Might Makes Right, who also performed genetic experiments on all his children while Sora was pregnant with them, against her will. She had to resort to taking a drug that poisoned and eventually killed her to save her quadruplet sons, but she only managed to save Sanji when they were born. One must wonder about the guilt and pain she felt, seeing how only one of her sons still retained his humanity that her monstrous, warmongering brute of a husband saw as as a removable weakness, instead all four of her sons like she intended.
    • Tamago's Devil Fruit powers (the Egg-Egg Fruit) are about as bizarre and disturbing as one can get, even for One Piece. Every time his body get torn apart, he dissolves into an egg yolk and reforms as a hideous-looking embryo which quickly evolves into a much stronger form in the life cycle of a chicken, going from a literal egg human to a chick human, and then a full-blown chicken human. And from what it looks like, those transformations are permanent. However, if he isn't hurt badly enough, Tamago simply gets maimed and lives with the scars even after his body successfully evolves. In other words, Tamago needed to be effectively killed twice over to reach the pinnacle form of his Devil Fruit and went years in combat without meeting someone dangerous enough to inflict the necessary wounds (and probably didn't want to, nor force the transformations to take place in a self-destructive manner, or end up butchered or dead as a result of the transformation failing to get triggered), and only Pedro was capable of carrying out the task. Now he's stuck as a chicken for the rest of his life in addition to having a maimed eye.
      • However, the fact that his followers speak openly about his transformations imply that they have already seen them before, which in turn implies that said transformations are reversible.
  • Chapter 854: Charlotte Linlin gleefully rehearses the wedding's details with Pudding, starting with the bride shooting her groom point blank when he lifts her veil for kissing her, and it gets worse from this.
  • Chapter 857: We learn the past of Capone Bege. He's an utter savage who allegedly DECAPITATED ANIMALS JUST TO WATCH THEIR BODIES TWITCH AND DIE. Worse, he earned his reputation because he targeted powerful criminal organizations and pirate groups that stood in his path in the exact same way- kill the head of each organization and no one else, then flee and watch the body squirm. He also planned to do this on Big Mom, by the way.
  • Chapter 859: Caesar Clown bombastically explains the mechanics behind the inhumane weapons he designed to poison Big Mom complete with a detailed explanation of the chemicals designed to murder her, and the whole time he's talking, he's got a twisted expression of utter, psychotic rapture on his face. Scarier yet is he has amassed enough poison to kill a normal person three times over and the plan is to use ALL of it on Big Mom simultaneously.
    • Turns out the seemingly invincible Big Mom has one glaring weakness. She endears a photo of someone named Mother Caramel, but if anything bad happens to it, she goes utterly ballistic. The fit she throws makes the ones she has when her eating disorder gets the better of her look like baby tantrums. The one time someone accidentally inflicted harm to the picture, she made a shrill, almost alien-sounding bloodcurdling wail, dropped to her knees and lost her body's fortuitousness, which scraped her knees badly enough to bleed out, and set off her Conqueror's Haki, causing her fellow family members and crew to faint- and we're not talking some weak, run-of-the-mill pirates fainting- it's potent enough to make the best of the best faint! Bege wants someone to split that photo in two, causing her to freak out and become vulnerable long enough to shoot her up with deadly poison.
    • It's not that surprising to hear a Yonko has Conqueror's Haki like Shanks, who can bring down 100,000 people in one blast, but he uses it for all the right reasons and possesses a level head. But knowing a batshit insane person possesses this power who could flip out at any moment without warning, knock her victims out, and then proceed to rip their life forces out while they lay unconscious if she dare so pleases is like installing a revolving door on the entrance to Hell itself and politely asking nothing to come through, just stopping short of laying out a welcome mat.
  • Chapter 860: It doubles as Black Comedy, but among the beverages offered at the Tea Party are fluids taken from living beings Charlotte Smoothie is willing to wring juices out of. They are a giraffe that makes a funny-sounding cry and a crazy islander who stabbed 100 men. The latter may have gotten a long-overdue taste of karma by suffering this fate... but what did that poor giraffe ever do...?
  • Chapter 861: The diabolical tea party is finally underway. And the chances of successfully rescuing Sanji look even more so bleak than ever.
    • Vito notices practically all of the oldest and strongest members of Big Mom's family are in attendance of the ceremony, including the unbeaten Sweet Commanders. He's scared stiff. This, coming from a man who lies down with an entire mafia as his bedfellows, is frightening in itself.
    • When a female door Homie overhears Bege's plan to assassinate Big Mom, all Bege has to do is look at the offending Homie and Gotti hacks her whole face off with a cutlass to quash a risk of loose lips, which falls to the ground like a hollow wooden mask and splits in two.
  • Chapter 862:
    • Need anymore proof that Big Mom has deadly plans for the wedding? The giant cake/altar for the event has a graveyard motif, complete with skulls and headstone crosses. Talk about poor taste. Although it's partially designed to look like the Germa Kingdom, which revels in bloodshed, if none of the uninformed Germa realized something was up by seeing that the cake itself is clearly modeled after death at an event where the cake should be a celebration of life, or worse, enjoyed that design, they're beyond hope. And for that matter, even if it was Halloween, who'd be able to eat a cake like that with a straight face?
    • Big Mom had a backup plan ready if Pudding failed to do her part. She wordlessly bobbles the pearl ring on her finger as a signal to the priest overseeing the wedding, and then he takes out a pistol that was easily concealed under his robes. Then, we see just about everyone else in her family is packing heat in the shadows, and she intends to murder off the Germa right in front of her guests.
    • And when that doesn't work, Katakuri lines up a shot at Sanji's head. Sanji makes a clean dodge, leaving the priest to catch the bullet... right between the eyes.
  • Chapter 863: Big Mom makes Nightmare Face after Nightmare Face, especially when she gives Jinbe a good staredown. An ultra-potent one at that.
    • The giant wedding cake took the head chef and his cooks days to complete, and probably left no opportunity to prepare a backup- had they thought to make one. When Luffy and his mirror doppelgangers mess up Big Mom's wedding cake, this becomes a fatal mistake: her eating disorder flares up and she demands a new one from the cooks- NOW. Needless to say, telling Big Mom to her face that you can't give her what she wants is an instant death sentence.
    Charlotte Linlin: "THOSE WHO STEAL MY FUN, I SHALL STEAL THEIR LIVES!"
    • It's noted Big Mom's power to steal life force and souls is from calling out to someone's very attachment to life. If the person is afraid of death or dying, that makes an attachment so great that she can kill them instantly!
  • Chapter 864: Big Mom becomes so angry at the sight of Mother Caramel's photo being broken that she does not have a freak-out like Bege had hoped she would. It did one better - she cannot even process her rage.
    • For a few seconds, it looks like she's having a big buildup to a total meltdown, as her eyes turn swirly and her face goes blank... and then she just stops. That's when the others realize she's become too angry to scream. What she just witnessed pissed her off so badly that her mind checked out on her, unable to deal with it. And all of her children are actually thankful for it, because they remember the last incident, where she instantly went berserk. In order for the plan to succeed at this point, Luffy has to force Big Mom to freak out by showing her the picture and making it impossible to ignore.
    • To top this all off, Katakuri, the man with the highest bounty and arguably biggest threat level among all the children there, is the most afraid of what's going to happen next, because he's already seen a glimpse of the imminent future, and it's terrified him enough to make him go pale.
  • Chapter 865: Big Mom finally sees the broken photo of Mother Carmel shoved right onto her face... and rips loose an ungodly bellow of Conqueror's Haki that completely levels the wedding hall as it ripples out for miles. Several pages are dedicated to her scream alone, showing it knocking out the weaker folks at the wedding, causing somebody to foam at the mouth, horrendously paining those who stayed conscious to hear it and those without earplugs to block it out, and rendering even the Sweet Commanders paralyzed.
    • Seeing Bege, Vito, and Gotti casually walk up to Big Mom to deliver the final blow is equal parts awesome and scary, but what really ratchets it more toward scary is they're taking advantage of her grief to initiate their killing strike. It's made clear that Big Mom really cared and loved Mother Carmel through a flashback that proves that Carmel was her caregiver as a little girl.
    • Bege's triumphant Slasher Smile as he prepares to bring the curtain down on his near-flawlessly executed assassination plan.
  • Chapter 866: Even as a child, Big Mom was a horrifying threat when it came to sweets. Fasting for seven days after tasting a delectable treat of semla drove her to such a point that she burned the village of Elbaf to the ground. Even one the warrior elders notes that she's not so much a child as she was a demon. And this was when Linlin was but five years old.
    • Five year old Linlin shows just how frightening being Obliviously Evil can be: she spanked a bear just once and killed it, she swatted a fly on a giant kid's face and broke many of his bones, tried to straighten a long arm tribe kid's arm, and tried to rip off the fins from a fish man child, all of this being well meaning but with disastrous results; in fact her destructiveness was why her parents had to abandon her.
    • Seeing Linlin acquire her swirly eyes of hunger mania for the first time as a little kid all because she enjoyed one especially delicious sweet. And that's before she's compared to a demon.
    • When the subject of a twelve-day cultural fast comes up and you know beforehand that you're going to subject someone with a lifelong eating disorder to it, you know it CANNOT end well. It marks the baleful beginnings of her insatiable cravings and not even the first catastrophe among a career spanning decades of razing places all in the name of sweets. Causing mass casualties from at least the age of five to sixty-eight? No wonder she became a Yonko.
  • Chapter 867:
    • Linlin killed several giants in the act of running berserk across Elbaf (the next chapter shows three freshly-dug graves for them with their gear marking their burial ground). One of them was even a legendary warrior who was too old to recover from his injuries and a hero among the giants.
    • Mother Carmel is actually a slave trader, who's been using her Orphanage of Love and Holy Mother image as a facade to sell children as Child Soldiers or slaves to the highest bidder, including the World Government. Worse, she's done so for fifty years.
    • Not to mention that Mother Caramel disappeared alongside with the rest of Linlin's friends at the girl's sixth birthday. She searched for them high and low, but they were nowhere to be found, leaving her scared, sad and alone on what was the happiest day of her life. At the age of six.
      • Making things even worse is a heavily implied scenario. Judging from the bite marks in the table and in the shredded clothing lying around Linlin when she was done eating, and the suspicious screams and cries shown on the last cutaway panel amidst the happy narration of how she remembers things, Linlin may have accidentally eaten Carmel and the children alive. While it is also possible that Carmel fled with the kids and set up this so Linlin thought shit happened (which brings its own set of Fridge Horror into the mix), the idea of the first possibility happening is still terrifying.
  • Chapter 868:
  • Ch 871 shows just a freakishly powerful the Big Mom Pirates really are, as they completely overwhelm Luffy, Sanji, and the Vinsmokes. Big Mom is such a monster, she's able to easily defend against Luffy's Gear Fourth Kong Gun (albeit with Busoshoku Haki), the same technique which previously overpowered Doflamingo and Cracker. And within mere moments, just blocking a single attack from Big Mom's freakishly powerful fist completely knocks out his transformation..
    • Luffy taunts Big Mom about taking down Kaido first and then coming back for her, but she laughs that he'll never defeat that "thing". Let that one sink in for a while: even one of the four most powerful people in the whole world who is regarded as a demon sees him as a threat and a creature.
    • Stussy, a major player of the criminal underworld and Big Mom's ally, is really an agent of Cipher Pol Aigis 0 under deep cover much like CP9 spent years building trust at Galley-La, and that flapper getup betrays a deadly vixen. She saw no problems in attempting to murder Du Feld while he was by himself and then have it covered up in the news and has a bizarre sniper-range version of the Shigan technique (the Finger Pistol). And it's very likely she's an Observation Haki user. She knew Morgans was watching from behind a corner, too.
    • Morgans is revealed as a manipulator of the truth who prints false stories in the world news, and Stussy strongarms him into doing it under pain of death. We also get some insight on how CP Aigis 0 was probably able to manipulate the newspapers that time Doflamingo lied about his resignation- murderous intimidation.
    • The booby trap inside the Tamatebako Box finally goes off when the box breaks open after Du Feld knocks it off the Whole Cake Chateau's cake layers until it finally crashes to the bottom, causing the dynamite inside to burst. The Minister of the Left did not say just how powerful it would be... a monumental explosion erupts from the box with such ferocity it breaks the foundation of the Chateau to bits and causes the entire thing to tip over. Now we know why the Minister of the Left got so scared when he heard it was stolen. He wasn't just worried about it falling into possession of a Yonko... he was worried it would go off in the wrong place and kill loads of innocent people, probably hoping it would be opened as soon as it was stolen, while in an unpopulated area. And worse yet, we've seen a bomb used by Crocodile with an even more powerful explosion that was meant to destroy an entire city, which someone survived at point blank range. And it wasn't even someone in the New World. The minister wasn't using overkill in the box- if anything, he was using the bare minimum that he needed to deal with the threats in his neck of the woods.
  • Chapter 872 ends with Big Mom's children getting ready to head after the Straw Hats and Firetank pirates only for Big Mom to enter one of her cravings, this time for the wedding cake that was just ruined. Charlotte Smoothie sees it happen firsthand, and one look at her mother's deranged state puts true terror in her. Even one of the top three most dangerous people among her family knows this means EXTREME trouble is right around the corner.
  • Chapter 873:
    • Big Mom has killed ANOTHER one of her children while suffering from hunger madness!! Charlotte Opera, P.O.S. though he may be, was implied to have tried to stop her, and died much the same way Charlotte Muscat did.
    • Big Mom is in the full throes of her craving-induced frenzy. By Katakuri's own admission, failure to give her what she wants could result in the destruction of her island territories when she goes on a rampage. And they can't re-build the cake she wants... because head chef Streusen got himself knocked out and suffered broken bones galore when he fell. And to make matters worse, she's pining away for something that she never tasted, so her children literally have zero ability to comprehend what she expects to sate her craving... until Pudding intervenes.
    • Think that Big Mom's feeding frenzy means that the Straw Hats will be able to escape in the confusion? Perospero begs to differ - by convincing her that the Straw Hats have taken some of the wedding cake, he's re-directed the berserk Big Mom in their direction.
      • Of course, Big Mom growls at Perospero that if she finds out this is all a lie, she'll murder him. The look of terror on the Candy-Candy man at his mother's Nightmare Face sells that this is no bluff.
    • Pudding plans on capturing her chef sister Chiffon to help make a replacement wedding cake. The Slasher Smile she sports while brandishing a pistol makes it clear that Chiffon's in trouble if Pudding catches up to her.
    • At the end of the chapter, Big Mom has caught up with the Straw Hats. It looks like a Hopeless Boss Fight is inevitable, now... and she's wielding Napoleon as a sword. Give a lunatic with the strength of a demon a sword? The danger meter just redlined. And then the next chapter reveals Big Mom learned to use the very same Giant's technique that Dorry and Brogy used to slay a giant killer fish.
  • Chapter 874:
    • Their firepower aside, Prometeus and Zeus are rather goofy characters, dangerous sure, but not particularly frightening, especially next to their creator. Then Prometeus goes all out, and it looks like something out of Majora's Mask. Poor King Baum...
