** [[spoiler:The fact that the Dazzling were able to do this by perverting ''ThePowerOfFriendship'' by getting the Humane Five to fight so they could steal their magic!]].

-->'''The Dazzlings:''' Now you need us, come and heed us, nothing can stop us now!

** The possibility that the Dazzlings [[spoiler: are not even safe from ''each other''. During the finals, there were moments where Aria and Sonata's mouths were not synching up with the lyrics, only still singing the chorus, while with Adagio it sounds like all three of their voices are being channeled through her, suggesting that at that point she can exert control over the others; further suggested by when her eyes glowed red, she was ''transferring'' her power to them instead of all three of them reaching point simultaneously.]]
** Even creepier is that, when they're singing, there's more than three voices singing at the same time. It gives the idea that there were more sirens than just the Dazzlings. What ever happened to them, though, is left up to the viewer.

And later in the actual movie, she starts making that face ''a lot''. Kinda makes you wonder just how mentally stable she is...

** It gets worse when you realize that this is what the Dazzlings plan to do to ''everyone on Earth'' if not stopped

* Just how damn ''effective'' the Dazzlings are as villains. They're smart (well, Adagio is, especially in the DangerouslyGenreSavvy department, Sonata's TheDitz and Aria isn't leader material), savy, utterly unscrupulous, and their plan makes a frightening sense. After taking over the school you can easily see them moving on to larger gigs, quickly becoming new pop-idols for millions, ''literally''. Unlike Sunset Shimmer, they left absolutely nothing to chance (one of the largely-cited problems with the last film was that if Twilight had just gone to Celestia and Luna, the events of the movie could have been avoided. This was the ''first'' thing Adagio went about eliminating). And ''nobody'' would be able to stop them because nobody would even understand that they ''need'' to be stopped. After all, universal adoration bordering on quasi-religious worship is what we've more or less come to ''expect'' from pop-star audiences. [[DystopiaJustifiesTheMeans And they aim not just to subjugate, but to cause strife and conflict to feed on, so the world under them would NOT be a happy place]]. You can easily believe that they nearly conquered Equestria once.

** The entire song is basically a weaponized version of an [[EarWorm Ear Worm]] to the viewers. You ''know'' that the Dazzlings are the bad guys and that the song is meant to convey that message, but you just can't stop listening to it. Celestia and Luna blissfully staring and the students swaying as the Dazzlings sing doesn't help much.

** To add to the above point, look closely at the Siren's appearance in the flashback sequence and again when they come out as [[spoiler: the avatars of the anthro!Dazzlings]]. They have 'fins'. What ponies in the MLP world had fins and lived in the ocean? 'Sea Ponies!'. It's freaking brilliant that the old image of the overly-happy Sea Ponies ('Call upon the Sea Ponies' anyone?) was completely subverted into a much darker idea.

** [[spoiler:They're ancient Sirens that once plunged Equestria into strife and disharmony, allowing them to nearly take it over until Star Swirl the Bearded banished them to the human world to defeat them because they would be powerless there. Except they weren't, and after Twilight brings magic to Canterlot High they begin to rebuild their power to terrifying levels.]]

* The Dazzlings' part in ''[[http://youtu.be/cfqhLM_k60c Welcome to the Show]]'', a dueling number with the Rainbooms, ''definitely'' counts. Not only is the beat and tone freaking terrifying, the Dazzling's opera-like singing borders on OminousLatinChanting at times and their dialog isn't much more calming at all. It's definitely the most ominous number for them. They sing it as [[spoiler:they obtain their true power again, transforming them into anthro forms and allowing them to begin their take over. It also allows them to summon avatars of their true forms, which are pretty frightening in their own right.]]

* A lesser example is Maud Pie's cameo during the slumber party; her human version's appearance has an UncannyValley vibe when illuminated in the dark kitchen.

* [[https://www.youtube.com/watch?v=Z9wpl2TZwKI "Under Our Spell"]] is quite the sinister song, even more so than "Let's Have a Battle". The latter could at least be interpreted as a motivational, if morally corrupt number, where as the former feels more like the villains are gloating over a victory you never saw coming. From the lyrics alone, the moment you're listening to the song, you are snared in their web, and by the time you realize it, ''it's already too late''. Celestia and Luna staring blissfully at

** The scary part is that the song is the antithesis to the first film's "Cafeteria Song": exact same situation of a musical number stirring up the student's passions into an eager flash mob, but the polar opposite message in the lyrics. With one song, the Dazzlings are tearing down the school spirit and unity that Twilight brought to the school, turning it into anarchy. The entire thing is ''heavily'' implied to be a HatePlague.

* The hatred CHS has for Sunset. If it was our world, Sunset probably would have been outright ''attacked'' by now! Or maybe she would have done something to herself...
* The girls go straight to Principal Celestia and Vice Principal Luna to get the Dazzlings kicked out after seeing their evil power in action. Celestia and Luna brush it off as Sunset trying to make someone else look bad out of spite and say how nice it was for the Dazzlings to put on a performance for them...and their eyes glow green, showing they're under the Dazzlings' spell too.

* [[VillainSong "Let's Have A Battle (Of the Bands)"]]. The Dazzlings come in with this incredibly eerie and spooky song, sowing chaos and competition among all the students, who start infighting, each suddenly wanting to climb their way to the top of the heap. They're clearly working some sort of magic from their jeweled necklaces, and the room fills with [[SicklyGreenGlow sickly green fog]], which the necklaces seem to be absorbing.

** Even scarier? If you look at "Battle of the Bands" that's ''exactly'' what happened to the student body, and likely to the viewer the first time viewing. The supernatural aspects and brainwashing didn't happen at the ''beginning'' of the song: they happened half way through. The first half was the hook, by the time they began brainwashing, everyone was already listening to the song.
