History Fanfic / DeathNoteEquestria

* InfractionDistraction: When the investigators bug her room, Twilight opens her desk secret compartment and pulls out an adult novel from the inside -- then procides to have ADateWithRosiePalms in front of the cameras. Nopony notices that there were other books in the compartment.

* InnerMonologue: In spades.

* {{Irony}}: Twilight's letters to Celestia drip with it when weaved in the context of the chapters.
** Twilight's actions cause the crime rate in general to drop, but the crime rate in Ponyville actually goes up, due to her controlling some of her victims into committing crimes.
* JadeColoredGlasses: Spike. Since dragons' physical development is tied to their psychology, he gradually grows through the story.

* JawDrop: Spike's reaction to the InfractionDistraction above.
* JumpingOffTheSlipperySlope: [[spoiler: To protect her identity, Twilight forces Rarity to kill Pinkie and then commit suicide.]]

* LegacyCharacter: L is only the latest pony to take up the name and mantle of the great detective. This lineage goes back ''1200 years''.

* LoveMakesYouEvil: [[spoiler: Fluttershy]]

* ManipulativeBastard: Twilight, so much.
** And then there's Mer -- after coercing [[spoiler: Applejack]] into being the Third Kira, she spun a (as we know, totally fictional) sob story that makes her seem like the LesserOfTwoEvils compared to Byuk and the original Kira. And on top of that, she says that Byuk is her corrupted brother who she's trying to defeat in order to save, thus playing on [[spoiler: Applejack]]'s strong sense of family to get them on her side.
* MemoryGambit: Similar to but not exactly like in the original plot.
* MythologyGag: Pinkie's [[spoiler: post-mortem]] gift to Twilight is a [[MemeticMutation bag of potato chips]].

* MyGodWhatHaveIDone: [[spoiler: Rarity's reaction when she realizes she's killed Pinkie, which leads to her suicide.]]

* NoHoldsBarredBeatdown: [[spoiler: Ditzy/Derpy nearly kills Applejack upon identifying her as Third Kira.]]

* OCStandIn: Lyra, Bon Bon, Jazz, and Colgate.

* OnlySaneMan: Rainbow Dash is the only one of the Mane 6 [[spoiler: who doesn't die or become Kira.]] In spite of her lowered competence, she holds onto her morality in the face of all the craziness around her, and generally reacts to things like her canon counterpart.
* OutsideContextProblem: Thanks to the Death Note (which even she doesn't understand fully), Twilight becomes this to the entire Equestrian government.

* PsychoSupporter: Second Kira for Kira.

* WeNeedADistraction: The Tri-Kira and their overly elaborate means of killing their victims is this for the use of the Death Note (though they themselves may not be aware of it), with the Tri-Kira as a whole serving as one for the Fourth Kira.
** [[spoiler: Except there is no Fourth Kira; the deaths blamed on them were planned by Twilight in advance as part of the MemoryGambit as a distraction, alongside everything about the Third Kira.]]

** Chapter 23's ending strongly implies that [[spoiler: Applejack]] is the Third Kira.
** Then Chapter 25 has L deduce that Third Kira is actually [[spoiler: all ''three'' apple siblings]], and they've been coerced into the role by [[spoiler: Granny Smith's murder]].

** Chapter 26: [[spoiler: Applejack: “Dash, that ain’t us.”]]

* TheFarmerAndTheViper: After the thief who killed angel was released on parole, Fluttershy found it in her heart to show him kindness. But, when his parole is over, he breaks into another house... ...And this time, he kills a little filly.

* DeadManWriting: Taken UpToEleven. Anticipating her death, [[spoiler: Pinkie Pie writes letters to everyone she ever met.]]

* LoadsAndLoadsOfCharacters: After [[spoiler: Twilight and Fluttershy]] join, L's team comes to a total of ten characters. The story also features the entire Mane Cast, both Princesses, a kidnapped filly and the team sent to rescue her, and the TakeAThirdOption duo of Ace and Spades.

* DistantDuet: A trio actually. Manga/DeathNote crossover or not, this is still MyLittlePony, so at one point three separate characters break into a song about the current events.

* NotSoDifferent: Colgate accuses Ace of being this to Kira, since his means of countering her -- convincing the Princesses to be harsher on criminals -- is to rule by fear, just like Kira.

* ForegoneConclusion: Averted. WordOfGod says that the ending will be much different then the anime/manga/film.
