History NightmareFuel / OnePunchMan

* At the beginning of the arc, King decides to get stronger by learning martial arts. He travels to various dojos but they all turn him down. Bang thinks his defensive style won't fit King's strength, Bomb thinks King is so strong that his alpha strike moves won't improve anything, the quipong instructor thinks he can't help King develop a new move, the savages are laying low, Sourface thinks his dojo is being hunted so they give King their sign, another thinks this is a power play from the Hero Association to get them on their side, etc. It's all culminates into being sent to the last dojo where one must mediate on their past and future. [[spoiler:In this case, death. The final sensei is a buddha who came there to die and subsequently mummified to show all warriors who come to this final place that no matter how strong you are, you will eventually die.]] King rightly freaks out, not ready for this kind of training and runs to the nearby waterfall to get water [[spoiler:and founds Garou undergoing the training.]] This breaks King and he almost decides that he should just throw himself onto the next monster he meets and be killed [[spoiler:until [[StatingTheSimpleSolution Saitama suggests that he just do basic strength training.]]]]

* In spite of the destruction of the Monster Association, the appearances of monsters not only continue, but are also ''increasing''. Not helping the matter is the fact that not only did the increase happen during Neo Heroes' debut, but Child Emperor's research shows that the monsters the new organization fought against were enhanced to make them stronger and were controlled with chips in their brain.

* Neo Hereos are regularly murdered or horrifically maimed by the monsters they fight unlike the Hero Association guys who run on ClapYourHandsIfYouBelieve CameBackStrong power boosts. The reason being that the Neo Hereos are often just ordinary civilians told they can can make a difference with, and be protected by, the power suits. This is an outright lie so that the Neo Heroes can have more mindless cybernetic slaves for their growing army. For what purpose? Who knows, but given that a lot of their leadership is power hungry executives and sadist criminals, it's probably not for anything good.

* People had doubts about Nyan being a legitimate dragon level threat due to him not doing much so far and even running away from Puri Puri Poisoner, one of the weakest S rank hero. Nyan coming out to the surface massacring the reserve heroes and trying to kill the hostage in front of them [[CatsAreMean for its]] [[ItAmusedMe own amusement]] while throwing in a few NightmareFace for good measure corrected that.

* Psykos's vision. She tried to look into the future and as a result saw something extremely bad. What exactly? No one know yet but [[TakeOurWordForIt it was apparently so bad]] she lost faith in humanity and decided [[TakeOverTheWorld that ruling over it]] wasn't worth it and that the only option left was to KillThemAll. When Fubuki ask her about it, she say she doesn't remember but the way she tremble with fear while she answer might be telling otherwise. On top of that, there is the possibility that what she saw was actually Shibabawa's vision.

* It seems Saitama or Boros are related to "God" and is manipulating things behind the scenes. After Boros punched Saitama into the moon, giant concentric circles were formed by the crater impact. At one point as Tatsumaki fought Psykos, a vision of the moon as a giant eye glared down on her and caused her to spew blood from the mouth and eyes, breaking her concentration. Whatever "God" is, it is extraordinarily powerful, it can give people great power for a simple wish, it can see everything through the moon (perhaps even being the moon), and it can drain and heavily damage the top level psychic known to humanity with just a "glance". Worse, it tried to give Flashy Flash, Saitama, and the monster they were with a proportion of its power through a extremely dense metal cube it controls. Blast then shows up and disposes of the cube before anyone can process what the cube is offering. We see Blast with another such cube almost 2 decades in the past in the facility Tatsumaki was kept in. This implies that the reason the top level hero of Earth is always absent from fighting normal monsters is because he's been undermining a god level threat for at least 2 decades. Despite that, the monster problem has only gotten '''worse''' meaning Blast seems to losing this fight.

** Saitama could have still escaped if he missed the moon by taking nearly any article of his clothing (a button, the head of his zipper) and simply flinging it in the opposite direction. Given his immense strength even a small amount of matter being propelled into space would have reversed his course and sent him back to earth.

* Just the entire setting in general is NightmareFuel, especially for normal people and even lower-tier heroes. Horrific monsters capable of anything from killing dozens of people to annihilating entire cities are practically common occurrences. Anyone can become a monster, even that one guy who just ate way too much crab one day and anything can set them off. Think the heroes will protect you? With the exception of those in S-Class (of which, there are only 17) and a scant handful of those in A and B Class, most of them seem to be just normal people in costumes. So the odds of them being strong enough to beat the monster of the week/day/hour is close to nil.

* Anything from eating too much crab to having a reptile obsession can turn you into a monster in this universe. Talk about ParanoiaFuel...

** One of the bonus chapters lessens this somewhat, as it shows that even the average C-class hero is far more physically capable than a normal person (not to mention the B- and A-Class heroes, who are typically many times stronger), which just makes it even more horrifying in hindsight because [[RedShirt they're still pretty much useless]].

* According to Koko's StatOVision Destro and Erimin have modified over 90 percent of their bodies which is not helped by their similarities of the Organization members.

* To remind the audience that Demon-Level and higher monsters are truly a dangerous threat, Zaedats' and his battle suit get crushed and Infelsinave has a hole in his torso after fighting against such monsters. Not to mention the several other Neo Heroes who are also at death's door once they faced a monster their battle suits could not penetrate and break through their defense.

* Despite claiming to have more morals than the corrupt Hero Association. Some of Neo Heroes' Neo Leaders are criminals who supposedly reformed by joining them, but is clearly rather doubtful:

** Speaking of which, the circumstance of Homeless Emperor's death. As he was about to give info about said character to Zombieman, said character took back Homeless Emperor's powers and life before he talked anymore, the implication being that he was perhaps [[HeKnowsTooMuch silenced before giving away said info]] which also imply Homeless Emperor was being watched.

* Garou with his "hero hunt". He is so strong that nearly all the S-Class heroes and others are unable to stop him. Especially in the end where he [[OneWingedAngel transformed into a monster]] and curb stomps even Tatsumaki. Fortunately he was given a [[BreakingSpeech lecture by Saitama]]

* Orochi's form post-splat, thanks to Saitama. Orochi's consciousness survives the impact, and the bits of his body that were spread all over the base begin moving back together. To make matters worse, the gores sticks to and absorbs any monsters in its path to get energy back. It then coalesces into a big blob of bloody guts and attacks Tatsumaki, yelling "GIVE ME YOUR BLOOD!"

* The House of Evolution conducts hundreds of dangerous experiments in order to create what he thinks are perfect beings, starting from animals then moving to humans. Judging by his creations, he would have nearly succeeded if it wasn't for Saitama. Zombieman was revealed to be one of his experiments.
* Carnage Kabuto is an exceptionally terrifying monster. From the fact that he's considered too destructive and violent by the House of Evolution, which had no problems with Beast King, to the way he punched a clone so hard that his torso turns inside out, to his Berserker Mode that sends him into an UnstoppableRage for ''an entire week,'' to some very disturbing facial expressions.
