* StatuesqueStunner: Much taller than Sunset Shimmer and having a figure akin to Adagio Dazzle, though not quite to the same level.

* LaserGuidedAmnesia: She wields the Memory Stone, an artifact that can erase memories. [[spoiler:This is played for maximum horror when she uses it on Monster X and removes ''all'' of his memories, turning him into an EmptyShell and the perfect body for Boreas to steal. She is later manipulated by Zephyrus into erasing Sci-Twi's memoies, allowing her to be posessed by Zephyrus]]

* VillainProtagonist: In the Equestria Girls portion of the story, they, along with the Dark Hunters, are the most prominent characters. However, this gradually becomes downplayed as [[TookALevelInKindness they lose their power seeking ambitions and find love and happiness]]. [[spoiler: Their targeting of the heroes in this story is due to a mistaken assumption that Princess Twilight hurt Sonata and stole her gem. Once Princess' Twilight's innocence is established, they work with her instead, albeit while still keeping her captive to deter retaliation from her allies and out of their inborn distrust out outsiders]].

* DemonicPossession: Right now, they are incorporeal and have to possess human hosts to affect the world. [[spoiler: Boreas is able to later possess Monster X when Wallflower erases his memories]].

** [[spoiler: Zephyrus suffers from a downplayed one after nearly being obliterated by the Rainbooms' magic. While his ability to scheme hasn't faded, he becomes increasingly more abusive and vituperative toward Wallflower, when trying to manipulate her into doing his bidding.

* ShadowArchetype: They represent waht the sirens would become if they completely surrendered their morality and only cared about power at the expense of others.

* AdaptationalHeroism: Gradually, the Sirens go from being selfish sea witches to developing a greater sense of camaraderie and friendship over the course of the Enjin Arc. [[DownplayedTrope However, they still retain small amounts of their viciousness, haughtiness, and paranoia]]. [[spoiler: Their response to Sonata's heart being stolen was to go apeshit on Princess Twilight and the Rainbooms, whom they believe to be responsible, and later for Aria to beat Sci-Twi within an inch of her life. Still it is a more selfless reason for going after the heroes than in canon]].

* WouldHurtAChild: In the past, they planned to murder the Rainbooms while they were children, and were only topped by [[spoiler: Wysteria]].

* BareYourMidriff: The most out of the Equestria Girls cast. It got plenty of guy's attention among other features.

* RelativelyFlimsyExcuse: Adagio Dazzle passes her off as her cousin, though it's abundantly clear she's not to anyone who knows the Sirens.

* SecretIdentity: Who exactly she is isn't clear at first. It's implied she might be a disguised Gloriosa Daisy. [[spoiler: She is eventually revealed to be Princess Twilight]].

* {{Tsundere}]: Even to her own allies, her compliments are often snide and backhanded.

** She's also not aware of the fact that [[spoiler: the Dark Hunters and the Sirens have kidnapped and are technically keeping Princess Twilight. Twilight herself goes along with their excuse that she is really visiting them of her own volition]].

* EvilCannotComprehendGood: Inverted. Zephyrus pretends to be a good guy to Sci-Twi and Wallflower, so that he can get them to do his bidding, thinking they were the good guys.

* SquishyWizard: With Zephyrus' help, she manages to be quite potent in battle. Without it, she is quite helpless, [[spoiler: allowing Aria to give her one hell of a beating]].

* BodyHorror: The "Frostbite Sparkle" is a far, ''far'' more grizzly version of the Midnight Sparkle form.

* OneSteveLimit: Averted and used as a plot point. Most of the cast didn't even know she existed and this causes the Sirens and Dark Hunters to mistakenly attack Princess Twilight Sparkle.
* TransformationTrauma: With gusto! The noises coming out of the Frostbite Sparkle that sound like unworldly wailing is actually her screaming in pain. The typical fiery glasses she had formed at fused to frozen tears coming out of clearly terrified eyes.
