“Subject 15- Official Title: Twilight Sparkle.
Reference Number: 05376-34289
Subject is currently aged 19, light build, lavender coat with purple eyes, and navy blue hair with a single stripe of light pink and purple next to one another. Genius level intellect, grasp of magic borders on top military personnel level.
Threat level- Currently Green, could possibly reach Orange if incited or activated.
Upkeep: Subject is to be kept unaware of status as Experimental, lest she face an existential crisis which could result in unnecessary casualties of civilians or possibly personnel. Subject is to be held in the company of two civilians who are to pose as parental figures for the entirety of her life, if necessary. Should she ever be activated or become aware of her origins, no fewer than five (5) top-class security personnel are to be dispatched to incapacitate. It should be noted that it has been decreed by Princess Celestia herself that the subject is not to be killed unless it is deemed absolutely necessary.
Subject 05376-34289 is a female unicorn purposefully raised to be a dormant weapon to be used by her Royal Majesty Princess Celestia should such a conflict where it would be necessary for her to do so arise.
Subject currently resides in Ponyville, where Princess Celestia, her self-appointed handler (whom it should be noted Subject 05376-34289 looks to as a dear mentor and friend, thus increasing possible use as a bodyguard should the need for activation arise), has instructed her to ‘learn of the magic of friendship.’ (Report #37). When asked to comment, Celestia stated that ‘(she) is a good pony. She deserves a normal life, despite what we’ve done to her.’ (Report #37)
Footnote 1: Subject was instrumental in the eradication of Nightmare Moon.
Footnote 2: Subject was instrumental in the dismissal of a parasprite (Subject 2) infestation.
Footnote 3: Subject was instrumental in the elimination of Discord (Subject 1)
Footnote 4: Subject was shown demonstrating “slight psychotic tendencies that may have resulted from her trauma as a youth” (from Celestia’s report, in relation to Incident #5638)
Footnote 5: Subject was successfully able, along with Shining Armor (who has been posing as her older sibling, personally hoofpicked by Celestia) and Princess Mi Amore Cadenza, to remove the Changeling threat from Canterlot during Incident #6792.

From the Diary of “Twilight Sparkle” (enchanted gift presented to Subject 05376-34289 by Princess Celestia that transmits a copy of her writings to an identical journal kept in the Restricted Wing of the Canterlot Archives):
“January 14th- For the past two weeks, I have been experiencing what I can only describe as horrific nightmares. Each night, I dream of the same place. A sterile white environment can be seen, and I am being forced to perform feats of magic above the magical ability I am able to successfully display even now. The pain is immense, and I beg the pony I have deemed ‘The Instructor’ to stop, but they refuse and insist that I comply, lest they return me to ‘Solitary Confinement’. I am unaware of the existence of such a place, but I fear that I may be repressing subconscious memories, for hearing that I may have to return to such a place evokes strong feelings of panic, fear, and in rare cases, rage. I fear sleep; despise it, even. I wish so badly for the nightmares to leave me alone, for these feelings of self-doubt and fear to dissipate so I may once again know peace. I fear for my sanity, and can feel myself spiraling down into bad places. Places in my mind no sane soul should ever have to witness... I feel myself changing, and I fear what I am becoming.”
