History NightmareFuel / AttackOnTitan

** Zackly pointing at Erwin during this little extra speech as he addresses not only the Commander but also us, the readers, and making sure TheFourthWallWillNotProtectYou as he gloatingly asks pointed rhetorical questions about whether you wanted to see justice done or to simply KickTheSonOfABitch until you feel uncomfortable?

** Gross also finally [[KickTheSonOfABitch meets his end by his very machinations]] shortly thereafter from Kruger pushing him into a space directly with the infamous [[FanNickname Kawaii Titan]]. At first he seems like he's in disbelief that Kruger just betrayed him or that he fell inside. [[OhCrap Then he freezes up upon noticing the Titan angrily glaring at him.]] The screams are as horrifying as they would be for any other Titan victim, and the worst part is that this is one of the few times in the series the reader/viewer may genuinely not be disturbed by them, or even ''celebrating it'' just because Gross was the biggest AssholeVictim in the franchise at this point, bar none.

* The fact that after all this horror, Ymir decides to continue serving the king even when she has acquired the power of a PhysicalGod and could easily kill him. Now, that's StockholmSyndrome.

'''BEWARE!!!!'''''

** Worse: [[WeUsedToBeFriends Connie, Jean and even]] ''[[TrueCompanions Armin]]' are all considering his death if it's confirmed that he wishes to commit further war crimes.

** As the world recovers from the Rumbling, technology progresses as well. Which unfortunately means so does weaponry. The nightmare may yet begin all over again when, many years later, the tree Eren's head is buried in grows into the same tree Ymir found all those centuries ago and a boy (who is hinted to be a descendant of Mikasa) hiking in the woods with his dog comes across it.

** The fact that the said titanization happens immediately after the secretary Muller and the rest of the Marleyans decide to fire their ammunition to the air and stop persecuting the Eldians. Moments after that said Eldians turn into flesh-eating monsters (though thankfully they don't go feast on the humans this time), proving the Marleyans that their FantasticRacism was ''the rational position'' on this problem, as the Eldians pose threat by their very existence, even if they don't intend to.

*** In the anime, the reveal is even worse. Eren tells it to Armin after showing him the state of the flattened world. Only it's not just covered in massive footprints. It's a sea of blood, of all his victims. A haunting sight to say the least.

** This chapter firmly emphasises the violent wedge that has been driven between Eren's rebelling faction and the Old Guard including all of Eren's original comrades. This is highlighted by Eren's determined and villainous demeanour after he has escaped his cell and meets up with his followers, barely reacting when Floch hands him a coat while casually mentioning that their infiltrators have just outright assassinated Zackly, Paradis's ''Head of State''.

** The fact that Titans are [[DaylightHorror primarily diurnal]] is also quite terrifying. Though it's a justified case, since they seem to [[PowerOfTheSun extract most of their energy from the sun]], it's still very unsettling because you can see that the world isn't some crappy and desolate place, [[SceneryPorn but a beautiful]] [[GhibliHills one]]. The world itself isn't a bad one: the Titans make it bad. And the fact that a person's last sight before they get eaten are gorgeous snow capped mountains and rolling valleys is not only horrifying, but depressing.

** The Wall Titans can ''swim''. A particular panel shows the giant silhouette of a Titan swimming right under a ship, like a giant sea-monster, before the crew onboard is seared alive by the massive amount of steam the Titan produces. In what follows, the entire fleet is easily wiped out as the Titans force their way through and get up. A truly horrifying sight shows the second line of defense, soldiers with cannons on the docks, as the enormous, black shapes of the Titans emerge from the wall of steam. Many soldiers run upon witnessing this, but it will doubtlessly be in vain.
