* CrazyAwesome: Aside from Pinkie Pie, there's also Sir Unimpressive:
--> '''Sir Unimpressive:''' ''Look! A shameless distraction!''
--> '''Puppets:''' [[MinionWithAnFInEvil *look*]]
--> '''Sir Unimpressive:''' ''Follow meeeeeeeee!''
--> '''Puppets:''' [[CrowningMomentOfFunny *follow*]]
** Esteem. He sees absolutely nothing wrong with murdering his own wife when she discovered his plan to overthrow Celestia, subjecting Rarity to TrainingFromHell to teach her bladecasting, jamming a [[ArtifactofDoom Artifact of Doom]] into [[EyeScream Twilight's eyeball]] to turn her into Titan's puppet, ruthlessly slaughtering any of his superiors and subordinates who refuse to support the new regime, and all on behalf of the EldritchAbomination he worships.
* CryForTheDevil: Terra gets a flashback chapter that shows how she became the way she is: [[spoiler: she had to MercyKill her brother/husband after Discord corrupted him, then Titan killed her mother for "betraying" him, forced her to be his new wife, and subjected her to the Insanity so that she'd become as brutal as him]]. It's kind of hard not to pity her after reading that.
* FridgeHorror: [[spoiler:Twilight gained the power of Queen Harmony, becoming able to match Titan, right? And then she drains Titan dry of magical power, [[NoManShouldHaveThisPower effectively becoming twice as powerful as him]]. I don't remember it being mentioned anywhere that she gave any of that power to anybody else, either. Just think that Titan almost destroyed Equestria and was able to steamroll Princesses Celestia and Luna, both of them at once, with ''half'' the power Twilight Sparkle now possesses. Now imagine what would happen if [[DrunkWithPower Twilight Sparkle went rogue]]. There is literally nothing in Equestria, probably nothing in the universe that could contain her.]]
* FridgeLogic: Apparently Nihilus used an Illusion spell against Rainbow Dash. But to what purpose, considering that during the early phases of the possession Nihilus looked just like Twilight Sparkle?
* HarsherInHindsight: Pinkie Pie knows every pony in Ponyville. Which means she knows ''everyone'' who died during Terra's attack on the town.
* HilariousInHindsight: Months after [[spoiler:Twilight became an alicorn]] in the penultimate chapter, the epilogue [[spoiler:with her coronation]] was posted ''the same day'' that news broke about [[spoiler:her becoming an alicorn princess in the season 3 finale]].
* MoralEventHorizon: Assuming he hadn't crossed it before, Titan using the Insanity on Terra to force her to kill thousands of ponies certainly counts.
* NeverLiveItDown: Apparently one of [[spoiler: Harmony]]'s earliest creature designs involved flaming hyenas. [[spoiler:Though the "flaming" part may well refer to the way the alicorns exterminated them.]]
-->[[spoiler:'''Harmony''']]: You always bring up the hyenas...
** Everything that Nihilus does to [[MindRape Rainbow Dash.]] Twilight is forced to ''watch.''
** General Esteem. Highlights include his abuse of Rarity, holding down Twilight and [[EyeScream forcing the Sliver into her eye]] and his [[AscendedToCarnivorism eating habits.]] He has ''incisors.'' He is a ''freaking horse''.
** Terra torturing [[spoiler: Celestia.]]
** Titan, in general.
* TheyWastedAPerfectlyGoodPlot: Pinkie's nature as an [[spoiler:arcpony]] can be seen as this. While Fluttershy uses her similar status as an [[spoiler:eraterus]] to [[spoiler:pit the most powerful dragon in Equestria against Titan]], in Pinkie's case it does not really serve any purpose except explaining her powers.
