** When the Death Knight focuses on the commanding officer, he tries to order his men to defend him, even offering a reward in gold. It does very little to help him as the Death Knight [[ImpaledWithExtremePrejudice skewers him]] [[DoubleTap even after he has collapsed to the ground]], leaving the man screaming in pain and begging for help. The remaining soldiers are left [[MookHorrorShow too horrified]] to continue fighting.
* When Captain Nigun of the [[FalseFlagOperation Sunlight Scripture]] prepares to kill Gazef Stronoff, he suddenly finds that Ainz has switched places with the Head Warrior. [[CurbStompBattle It all goes downhill from there]] [[MookHorrorShow as his ego is thoroughly obliterated]]:

** Backed against a corner and with nothing left to lose, Nigun decides to use his trump card. Ainz decides to take caution for once and asks Albedo to defend him. When Nigun summons [[EliteMook Dominion Authority]], a 7th tier Summon, a seemingly shocked Ainz expresses disbelief... [[FacePalm at himself.]] ''[[AntiClimaxBoss For "putting up his guard against such child's play".]]'' [[note]]This happens because Ainz fears the possibility of a Seraph Empyrean being summoned against him; said Seraph is a level 90 monster that needs him to fight seriously. On the other hand, the Dominion Authority Nigun summoned is a ''mid-level'' monster back in ''YGGDRASIL'' that's only considered very powerful and difficult to summon for New World standards, where level 30 beings are already considered legendary. Ainz, as a level 100 player, has understandably no issue killing it.[[/note]]

** Ainz isn't even the first YGGDRASIL player who ended up in the New World. Every once in a blue moon, for whatever reason, YGGDRASIL players are deported from the game into the New World and they were so powerful that they're essentially revered as Gods by the New World. The Six Gods are YGGDRASIL players, the Eight Greed Kings are more YGGDRASIL players, and it's implied that the "evil deities" the Thirteen Heroes fought are leftover [=NPCs=] from the Six Gods' deaths. The only reason the Six Gods were taken down is because a large portion of their guild is still human or mortal and can die and the remaining undead player is still no match for eight players, and the Eight Greed Kings only came to a pass because they went infighting and became weaker and weaker, at which none of these are a problem for Ainz/Momonga because he is the only sapient and sentient person deported in and his player avatar is an undead. It only goes to tell how horribly helpless the New World is when [[HumansAreCthulhu perfectly ordinary people who get stuck in their video game characters on the other side of the world are considered eldritch abominations of the worst caliber]]. Last but no least, given the comments from New Worlders about Nazarick being unprecedented, these players are likely ''not even close to Momonga's level''. It's so bad that humanity in the New World would be obliterated if not for these players being spirited in.
* The New World itself is a terrifying example of what a fantasy world would really look like. It's ''dangerous.'' Humanity can only thrive on one small part of the known continent due to dangerous predator races who very much see humans as [[ToServeMan food sources.]] And to add to the problem, the few human nations undermine one another even at the best of times. Learning magic is not as simple as just picking up a spellbook and hoping to become a [[TheArchmage legendary mage]] in a few years, since the average person is limited to Tier 3 spellwork. Magical research has barely hit its Renaissance Age, meaning that magic is not a convenience the everyday person can use to better their lives. And humanity's lot was ''even worse'' before the Six Gods (more YGGDRASIL players who got spirited into the New World like Ainz) introduced Tier Magic and displaced Wild Magic, which is the only reason humans stand any chance against the predators who want to eat them. And that's even ''before'' Ainz and his equally overpowered [=NPCs=] show up to makes things infinitely worse.

* The ''infamous'' "Holy Bludgeon" incident where the Holy Queen is used as a bludgeon by Jaldabaoth (not Demiurge, but a high-level demon who swapped places with him) against her own troops, the narration describing the utter destruction of her body in excruciating detail. [[SerialEscalation At least Clementine up there still HAS a face.]] By the time Jaldabaoth shows up again the top half of her corpse has rotted away. This is one of the most notoriously horrific Nazarick atrocities in the ''entire'' light novel and stacks up pretty nicely with the Katze Plains massacre, and is heavily speculated by fans to be one of the few the reason why the entire Holy Kingdom arc had to be put into a movie adaptation rather than simply being broadcasted on the TV.
