History YMMV / ThreeBelow

* ToughActToFollow: Averted. Many ''Trollhunters'' fans like ''3Below'' because of its good quality, heartwarming moments, and fish-out-of-water humor.

* EnsembleDarkhorse:

* ShipsThatPassInTheNight: Krel/Eli, which has gotten traction over the idea of it being a companion couple to Steve/Aja and that Eli, with his nerdy personality, would be attracted to a super intelligent alien.

* WhatDoYouMeanItsNotPolitical: Colonel Kubritz is a US government official who detains and captures "illegal aliens" without trial or jury, imprisoning them indefinitely with the paper-thin pretense of protecting the country even if it comes at the expense of actual legal citizens. She also dismisses all evidence to the contrary (even from her own allies), doubling down on her decisions and siding with an Authoritarian figure everyone else says is untrustworthy. It does not help that Krel - one of her two biggest targets - has a human form deliberately made to look latino.

** In the series finale, [[spoiler: Krel [[IChooseToStay decides to remain on Earth]] because he considers it his new home and he wants to remain with the friends he made there. Meanwhile, Aja chooses to return to Akaradion-5 to [[RightfulKingReturns accept the planet's throne]] and help repair the damage Morando had done during his rule. These are two choices refugees have to make when the trouble in their home countries subside; either remain in their adopted homes and continue with the lives they had created there or return to their original homelands to help rebuild them]].

** In "Ill-Gotten Gains", Krel and Aja's human friends chase Area 49B away by threatening to record Kubritz' xenophobic statements on their phones and make them go viral on social media if she doesn't leave Aja and Krel alone, a popular technique that minorities and their allies use to defend themselves from bigots with authority.

* AuthorsSavingThrow:
** In the previous series, Claire's mom, as soon as she finds out Trolls exist, wants to warn the mayor about the impending apocalypse underneath Acadia because the mayor has a duty to protect the city, and the people of Arcadia should know they're in danger. However, the Trollhunters talk her out of it because if the masquerade breaks, then the Trollmarket refugees and the humans of Arcadia will be imperiled by this sudden change in status quo, especially with Gunmar on the way and humans lacking the necessary firepower, [[StrawmanHasAPoint despite the very good points Mrs. Nuñez brought up about getting as much help as they could to fight Gunmar and Morgana]]. When the Tarrons find out that Morrando is planning on invading Earth, they immediately decide to alert the Earthan Authorities and recruit as many allies as they can despite the threat of Area 49-B because they know they can't take on Morrando's army alone.
** Some characters who were underdeveloped in the previous series were given greater depth in this one. The most notable being Uhl, who went from being an unsympathetic overly stern teacher to a JerkWithAHeartOfGold who becomes fiercely protective of Aja and Krel.

* AlternateCharacterInterpretation:Is Kubritz's last minute betrayal of Morando after finally seeing the monster he truly is a genuine attempt to redeem herself, or simply a pragmatic way of self-preservation since destroying Earth would mean that she can't become the supreme power with alien technology? Also was her horror at seeing Tronos killed a case of genuine, albeit hypocritical case of standards or simply her being afraid of being the next YouHaveFailedMe target of Morando?
* {{Applicability}}:

** Sergeant Costa is the OnlySaneMan working for Kubritz, but he ''did'' participate in betraying the Tarrons after their Enemymine with Warehouse 51 ended as well as arrest the Blanks, Aaargh, Toby, Steve and Eli for the crime of defending their friends. Not to mention it's implied he also experimented on their alien captures. Thus, when he comes and turns himself into the Tarrons, Varvatos puts him in a well-deserved NeckLift and asks why they should trust him when Ares 49B lied before. Costa is terrified but admits they have a point. We also find out it wasn't a FakeDefector trick; he really did warn them about [[spoiler:Kubritz attacking the town]]!

** The Zenon Brotherhood crosses it by kidnapping Varvatos in season 2 after his attempted SuicideMission and gloating about how they're going to deliver him to Morando for eternal torture.

* CompleteMonster: [[ManipulativeBastard General Val Morando]] is a would-be GalacticConqueror who, in the premiere, takes over the planet Akiridion-5 and reduces it to a fascistic hellhole through a brutal coup. Morando plays Varvatos Vex, the defender of the royal family, for years, having murdered Vex's entire family alongside hundreds of other innocent people simply to use a fake pretext to manipulate Vex. When Vex catches onto his lies, Morando gleefully pledges to [[ForcedToWatch make Vex watch]] as he kills his new FamilyOfChoice instead. Throughout the series, Morando murders failed minions and bounty hunters, sometimes for reasons as petty as delivering bad news; strings along the bigoted Colonel Kubritz before killing her as well when she disobeys him; kills many of the heroes' allies; and attempts to transform himself into a god in order to [[InTheirOwnImage destroy and remake the entire universe]] to give it the "order" he so craves, nearly wiping out much of Arcadia Bay in the process.

** Kubritz crosses it in the SeriesFinale. Before, she at least had some standards about Earth not getting killed. To emphasize how bad this is, Agent Costas turns himself into the Akiridions and explains he can't side with her on her scheme to lure out the Tarrons: [[spoiler:by taking everyone in Arcadia hostage under the guise of "martial law". To show she's snapped, she starts firing at innocent civilians at the screening of Toby's movie, who at first mistake it as AllPartOfTheShow. Then she rounds them up and threatens to murder them all if they don't give up the Tarrons, taking up Eli in a NeckLift when he fires ninja stars at her. Detective Scott refuses to recognize her word as law, since JurisdictionFriction doesn't begin to cover her war crimes against the people he's sworn to protect]]. It's no surprise that [[spoiler:though Aja convinces her that Morando is going to destroy the Earth anyway, no one mourns Kubritz when Morando crushes her with a car and blows her up to boot]].

* IdiotPlot:
** The reason why the whole show happens is that [[spoiler:Vex actually believed Morando would stage a bloodless coup and no one would get hurt in exchange for getting the chance to avenge his family. Thanks to that action, he gets dozens of aliens killed and starts a power vacuum. He does try to make up for it by keeping the kids safe but has to do so on a "mud planet" where his warrior behavior makes him look like an unfit guardian to the local authorities and bounty hunters can come at any time. It even gets lampshaded in the show itself when Aja and Krel find out and are beyond furious to know their suffering could have been avoided]].
** Colonel Kubritz with her Area 66 management turns her subplot into this. While targeting Aja and Krel for breaking into her facility and making her men look like fools is understandable, [[spoiler:releasing an electric being who claims the two are wanted fugitives with a huge bounty isn't after he caused a city-wide power outage and was supposedly attacking civilians]]. And of course, there is the bit where [[spoiler:she works with General Morando to capture the royals and not realizing that he's genocidal, xenocidal, and power-hungry. The Arcadian locals when they find out tell her that she's no better than the alien betters she's supposedly fighting. Eventually, Kubritz pays for the betrayal of Earth-- with her life]].

* WhatAnIdiot: Considering that Seamus's father was being outwardly racist towards Krei and implying that a brown-skinned kid new to the country couldn't be good at math, he has no leg to stand on for accusing him of cheating. Therefore, Senor Uhl should have said as much since comments like that in real life can lead to rather controversial court cases. Instead, he and Miss Janeth agree to humor Seamus's father and have the boys participate in a math duel. Varvatos himself comes off as the most reasonable one when he threatens to skin Seamus to get new curtain drapes since he takes none of the nonsense.

* CompleteMonster: [[BigBad General Val Morando]], the exiled leader of the Talyon Phalanx, is an inveterate [[ManipulativeBastard user of disposable pawns]] who fancies himself a GalacticConqueror. [[Recap/ThreeBelowS1E1TerraIncognitaPartOne In the premiere]], Morando [[TheUsurper seizes the throne]] by launching a destructive coup on Akiridion-5, oppressing the populace, with their resistance punished with death. Morando manipulates the royals' protector, Varvatos Vex, by having a civilian satellite destroyed to kill Vex's family and hundreds of innocents with them, using it to turn him against the royals and gleefully pledging to [[ForcedToWatch make him watch]] as he kills his new family when Vex realizes he's been played. Throughout the series, Morando attempts to torture one of the heroes' allies into becoming his new general; [[BadBoss murders]] his failed minions and bounty hunters for reasons as petty as delivering him bad news; falsely promises the bigoted Colonel Kubritz a world without aliens, before killing her when she disobeys him; lobs a meteorite at Earth merely to disguise his own arrival upon it; and, after slaughtering his way through swathes of the royals' allies, integrates himself with the core of Gaylen to make himself a virtual god, intent on destroying and [[InTheirOwnImage reshaping the universe]] to give it the "order" he so craves.
