History YMMV / TheLastKidsOnEarth

** [[BigBad Rezzoch the Ancient, Destructor of Worlds]] herself, is an ancient being who devours worlds and is the one responsible for [[TheEndOfTheWorldAsWeKnowIt the apocalypse]]. She razed the monsters' original world and plans to do the same to Earth with the help of her servant Thrull. Abandoning Thrull after [[YouHaveFailedMe his failure]], Rezzoch possesses and mutates King Wrench in order to use him as a doorway to Earth. Rezzoch plans to make Jake Sullivan her vessel, subjecting him to MindRape, and tries to kill all his friends out of spite.

* CompleteMonster: [[ManipulativeBastard Thrull]], though [[EvilMentor pretending to be a friendly mentor]] to the young heroes, particular Jack Sullivan, is in truth a sadistic servant of the [[PlanetEater world-devouring being Rezzoch]], and intends to feed Earth to his master. Intending on giving his supposed friends to Rezzoch as [[ToServeMan appetizers]], Thrull [[{{Sadist}} relishes in the emotional pain his betrayal causes]] before attempting to summon Rezzoch so she might consume any living thing on Earth and exalt him above her other followers.

* AuthorsSavingThrow: The book's weak point is depicting June as a slightly generic at best TheSmurfettePrinciple. Somewhat justified, as the book itself is written from Jack's point of view. The show fixes the aforementioned issue by adding in some scenes from June's perspective.

* CompleteMonster: [[TheHeavy Thrull]] is a power-hungry sociopath with a serious case of ChronicBackstabbingDisorder. Thrull gains the trust of hero Jack Sullivan and his friends to trick them into completing a magical bestiary, with which he plans to summon [[BigBad Rezzoch]], and feed the monsters he befriended to his master as an appetizer; Thrull does this despite knowing that Rezzoch could destroy humanity. Forming an alliance with Evie Snark after his plan is thwarted, Thrull betrays her as well and [[HeroKiller murders the heroic Bardle]] for more power. Thrull proceeds to use his newfound power to [[NightOfTheLivingMooks raise an army of the dead]] to help summon Rezzoch. When Thrull locates the heroes in a mall populated by thousands of benevolent monsters, he orders his army to massacre everyone when they refuse to surrender. When he has Jack at his mercy, Thrull gloats that he will resurrect him as a mindless slave after killing him and use him to kill his friends.

* UnexpectedCharacter: The video game based on the show, ''The Last Kids on Earth and the Staff of Doom'', features Meathook as one of the bosses. While Meathook was introduced in the last scene of the show's Book 3, he is more prominent in the following book, which was never adapted for the show. Confusingly, Jack and the others treat Meathook like they already faced him.

** Jack. Is he acting like a 13 year old would during the apocalypse, albeit trying to put his own spin on survival, or did he have a complete mental break and is hiding it with his video game terminology? He is making the best of a terrible situation but some things he does makes it seem he does not fully grasp the situation. Multiple moments involve him endangering his friends that, while not for selfish reasons, put them at risk. Also, he views things through a video game lens, like his friends "happiness meter", that makes it seem like he is not entirely sane.

** Despite what the title would suggest, the show is a comedy for the most part, and Jack and his friends aren't as traumatized like one would expect thirteen year olds to be in dire circumstances. They also don't seem too bothered about the fact that ''people that they know'' (Quint's babysitter, various teachers from their school) have become zombies, even though there's no cure for it, and zombies getting killed is a plot point in Book 2.
** Jack, however, does reflect on this a lot, most notably in his conversation with June. He is aware of how horrible things are, but chooses to make the best out of his situation and not think about it too much.

** Angst is recognized over the course of Book 2, and is a main plot point in episode 7 when the kids visit June's home.
* AuthorsSavingThrow: The book's weak point is depicting June as a slightly generic at best TheSmurfettePrinciple. Somewhat justified as the book itself is written through Jack's point of view. With the show fixing the aforementioned issue by adding in some scenes from June's perspective.

* WhatDoYouMeanItsForKids: In spite of being aimed for children, the show itself does actually make the monsters more threatening to the point of almost endangering out main characters (who are in fact, 13 year olds.) Even the zombies are NightmareFuel for children who have phobias for zombies. There is also a graphic depiction of gore in some scenes (First, when Jack stabs Blarg on the eye, and second, [[spoiler:when he kills Blarg by stabbing its brain)]].
** Made even worse for the original books and even the show, where it gets darker ever since Book 2 (Zombie Parade).
