History YMMV / DisgaeaD2ABrighterDarkness

** [[spoiler: The second battle against Xenolith]] is nigh universally agreed upon to be the hardest non-BonusBoss in the entire series. He's the weakest main story final boss base stat wise, but his evility more than makes up for it. It siphons 3% of the base stats of any character within 10 spaces of him, gaining up to 30% of their base stats. That's right: he renders grinding, a simple and powerful strategy, completely and utterly '''useless'''. A proper plan and intelligent team composition are actually required for once, which can throw off anybody who just powers their way through the games.

* FridgeLogic: [[spoiler:According to the artbook, Sicily is 937; nearly 400 years younger than Laharl. Are we seriously expected to believe their human mother lived for ''that long'' after she had Laharl?]]
** [[spoiler: Well, [[WizardsLiveLonger She was a witch]].]]
** FridgeBrilliance: [[spoiler: A netherworld's effects on aging rates could potentially work on humans too]].
** FridgeHorror: The Overlord Sicily and Pure Flonne the Awakened Angel are too light and comedic to be considered Bad Endings [[spoiler: until you consider that there was nobody to rescue the Angels kidnapped by Xenolith.]]

* AuthorsSavingThrow: Some fans took issue in the first game about how Laharl's Mom's sacrifice to save Laharl was interpreted as a sin, leading to her becoming a Prinny. [[spoiler:The issue rectified a bit by revealing that she always had the choice of becoming an angel instead. She chose Prinnyhood so that Sicily, who she was pregnant with at the time, would live.]]

* TrueNeutral: Barbara refuses to do anything without being given an order, and doesn't appear to have any concept of morality.

* UncannyValley: While likely intentional given how it's mentioned the work on them was done hastily, Laharl's statues look surprisingly creepy.

* MemeticMutation: Laharl is wearing pants! [[labelnote:explanation]]Laharl's [[WhoWearsShortShorts shorts]] have become such an iconic part of his character design (alongside his antenna hair and scarf) that when his new character design showed that he traded them for pants, many fans became far more fixated on his new pants than on anything else.[[/labelnote]]

* SugarWiki/VisualEffectsOfAwesome: Holy crap, [[https://www.youtube.com/watch?v=xlDz__n8rxY the opening!]]
* WhatAnIdiot: Barbara doesn't try to win her first fight with Laharl because she wasn't ordered to [[spoiler: and in one of the bad endings, doesn't run for her life when a black hole forms because she wasn't ordered to.]]

* ThatOneAchievement: Special Voyeur requires that you see every single special attack animation. This normally would have been easy, if a little time consuming, were it not for the fact that it includes the 3 unique skills of [[spoiler: Xenolith's first phase]] and [[spoiler: Darkdeath Evilman]]. You will only ever fight either boss once per cycle, meaning that if they go down before you get to see their skills, you have to start a new cycle just to see them. It can still be a pain in the ass trying to view them even if you're trying to, as there's no guarantee that they'll use all three in one fight, though that's mitigated by the fact that getting a GameOver in this game will simply send you back to the castle.

* GameBreaker: As usual, the DLC characters include some:
** Salvatore because her evility. It performs one of several randomly selected buffs to adjacent allies, but when the options are increasing movement by 10, range of attacks and spells by 9, jump by 99, doubling damage dealt, and cutting damage taken down to 10 percent of normal, you can't really complain.
** Pram's evility includes poison (that always hits), a hit on a random enemy, a free 50% INT boost for all allies, a 100% Attack boost for herself and 50% evasion for all units.
** Then we have [[VideoGame/PhantomBrave Marona]]. Her signature confine skill brings back defeated units for the battle. Quite useful for a team of {{Glass Cannon}}s, {{Squishy Wizard}}s, {{Fragile Speedster}}s or generally underpowered parties.
** [[VideoGame/LaPucelle Human Priere]] brings with her the Purify Power evility, which, when damaging a unit, spreads that damage to adjacent unit and all other after it with decreased damaged as it spreads further out. With the right setup, a character can clear an entire Item World floor. The best part is that the character with Purify Power gets all gains (EXP, Mana, HL, and even Land of Carnage stats) from every unit killed this way.

* CharacterRerailment: The main cast has been hit hard by {{Flanderization}} in their guest appearances over the years since the first game, which at first glance seems to have stuck as of the beginning of this game. In truth, it's more a case of JerkassFacade and VitriolicBestBuds than anything, and the character development did stick (and in fact gets expounded on), it's just not obvious from their day-to-day interactions.

* AwesomeMusic: Dramatic Devil Story is fittingly epic for [[spoiler: the battle with Xenolith]].
* BrokenBase: The return of the Weapon Mastery System. As mentioned on the main YMMV page, some fans were glad to see it go when Disgaea 3 came out while others weren't as enthusiastic. While being able to tweak the Weapon Mastery rate with the Cheat Shop and some other changes help alleviate some of the backlash, the base is still divided on which of the two methods of gaining skills was better.

* VisualEffectsOfAwesome: Holy crap, [[https://www.youtube.com/watch?v=xlDz__n8rxY the opening!]]

* [[DesignatedVillain Designated Evil]]: The spreading of the Yuie flowers for most of the game. Everyone tries to stop it because it will turn the Netherworld into another Celestia, even though the worst thing that they do is cause minor changes to demons which are only temporary. [[spoiler: It's not until it turns out that Xenolith is having angels drained of their life, essentially killing them to do it that it's revealed to actually be bad thing.]]
