History Characters / MassEffectTheEquestrianEquation

* TragicHero: She's as nice ([[BewareTheNiceOne and ruthless when pressed]]) as in canon, but had to do millennia of antagonistic things to keep her ponies well off. This hits the fan once exposed [[spoiler:and she has to sacrifice herself and her world to stop it from harming them]].

* VillainousBreakdown: When Shepard confronts him in the Harmony Core chamber over [[spoiler: how Discord has been manipulating him the whole time,]] he becomes increasingly irate and incoherent to the point where he's shouting like a crazy person.

* AntiVillain: [[SlidingScaleOfAntiVillains Type III]]. Regardless of her methods, she never stopped caring about her little ponies, and everything that she did was in the name of keeping them safe. [[spoiler:When Shepard makes her realize that the Reapers will inevitably discover Equestria regardless of her best efforts, she ceases to be antagonistic and makes peace with her faithful student before her systems shut down.]]
* BrokenPedestal: When Twilight discovers that the mentor she idolized was far from the paragon of virtue she believed her to be.
%%* LoveMakesYouCrazy:
* MyGodWhatHaveIDone: Once she gets so desperate to stop Shepard and co. that [[spoiler:she transfers her authority to Discord, who provides to summon a simulated Reaper invasion]], she admits she was wrong and spends the rest of the story trying to fix things.
* RebuiltPedestal: She and Twilight make peace before saying their final goodbyes.

* BadassBluff: Helps Twilight give one to Dr. Hern's husband from recovering her for Cerberus and to keep Applejack from going to prison.

* InterspeciesRomance: With Tali.

* LeroyJenkins: She pays dearly for this mindset.

* MadScientist: A friendly version when in the real world. Initially deconstructed when Twilight warns her they ''don't'' have unlimited resources and she's too valuable to risk her well being.

* MadScientist: A friendly version when in the real world. Initially deconstructed when

* DirtyCoward: His main motivation [[spoiler:is to save himself from the imminent failure of the Equestria simulation when the Harmony Core goes dead and is more than willing to doom all the ponies to do it].]

* GuileHero: The way he deals with the scandal surrounding Applejack's well-intentioned but illegal actions, he maneuvers Dr. Hern's husband into dropping the charges while at the same time ensuring that Dr. Hern will remain on the Citadel where she can be treated without the risk of exacerbating her condition that would come with interstellar travel. And then to top it all off, he gives a very pointed hint that he knows Dr. Hern and her husband [[spoiler: both work for Cerberus, something that, if brought to light, would make it virtually impossible for Cerberus to extract Dr. Hern]].

* DidYouJustPunchOutCthulhu: Adds [[spoiler:Celestia and Discord]] to the list of godly powerful being who opposed him and lost.

* BroughtDownToBadass: Even outside Equestria, she's a ''very'' powerful biotic (arguably the most powerful in the galaxy, even ''without'' implants!).

* OneManArmy: Goes into this mode when rescuing her abducted people from the asari merc who attacked New Ponyville. Her biotics allow her to plow through the security mechs between her and the asari (and this is still ''before'' she gets a biotic amp), and she isn't truly in danger of being overwhelmed until the asari breaks out a pair of YMIR heavy mechs.

%%* ShockAndAwe: Her omni-hoof has the "Overload" power.

* WrongGenreSavvy: Figures that gumption and hard work are all that will be needed to get New Ponyville on its feet financially, without considering that a workforce of hooved quadrupeds who have considerable difficulty using tools designed for other species (not to mention the increased liability that comes from them being an endangered species) makes them less than viable to many employers.
** UpToEleven: At the beginning of the second arc, she [[spoiler:abducts the comatose Dr. Hern from the hospital when she believes that she is in danger. Twilight and Forty-Two have to explain to her that, unlike in Equestria, it'll take more than a heartfelt apology and a friendship report to make up for the multiple felonies she's committed, even if it was with good intentions.]]

* KnowWhenToFoldEm: Having watching Twilight single-hoofedly demolish her security mechs, she opts to lay down her weapons and remove her biotic amp once face-to-face with her.

!!!A helpful Changeling Drone who makes appearances throughout ''The Equestrian Equation''. By the end of that story, Twilight makes 42 her [[RobotBuddy personal assistant]] [[spoiler:because he reveals himself to be a sentient AI whose code is very similar to that of her "number one assistant" Spike. Pretends to be an emotionless VI in public, but in private displays a familiar sense of humor.]]
%%* HyperCompetentSidekick

%%* ShockAndAwe:

* [[BigDamnHeroes Big Damn Hero]]: Come on, he's Shepard. You knew this already.

* [[TheseHandsHaveKilled These Hooves Have Killed]]: [[spoiler:After exiting the simulation, an arrogant Milligan attacks her, thinking she's powerless, only for her biotics to stop the bullets. Since she gave him his LastSecondChance, she then proceeds to follow her ancestor's policy and give him a NoHoldsBarredBeatdown with her powers, ultimately sending him ''through'' a railing and into the Harmony Core. She then has a moment of remorse, but Shepard is there to comfort her]].

* MadScientist: A friendly version when in the real world.

* DirtyCoward: His main motivation [[spoiler:is to save himself from the imminent failure of the Equestria simulation when the Harmony Core goes dead and is more than willing to doom all the ponies to do it.]]
* DissonantSerenity: After his plan to [[spoiler:free himself from the Equestria servers by getting Dr. Milligan to upload his program out]] fails, Discord actually gets so furious that he overloads some of his emotional subroutines. After that, he sits back and calmly enjoys [[spoiler:watching Equestria burn courtesy of his simulated Reapers.]]
