I cast a shield in front of me and Nightmare Moon, cloaking us from view. The six mares and baby dragon enter the room and celebrate the end of one long journey. Twilight picks up the five Elements, handing them out one by one. Lastly, she reveals herself as the Element of Magic and how that works before it appears to her. The Elements transform into jewelry for their Bearers, matching their cutie marks.
I nod to Nightmare Moon, dropping her shield. She rises to confront the would-be heroes. "Those toys can do no good for you!" The Bearers spin on her and the Elements light up-
"NO!" I drop my shield as I teleport in front of her, casting my magic out to meet the Elements' head-on. I push as hard as I can, actually holding off the magic force until both explode. The explosion in my face rops my armor off, sending the plates flying. I blink as the explosion clears almost instantly.
That leaves my revealed form to be seen by all. My coat is pitch black, my medium-length mane is pale blue, my horn sprouts from my forehead curved and ragged, and my eyes are large, blue and dragonic. My meddlings have warped me. I growl at the Bearers, showing my sharp teeth. "You won't take her from me again!"
"What are you?!" squeeks Rarity.
"An old pony bent on saving the Princess of the Night!" I growl. I feel tears of weakness as they stare at my now-fragile form. I push them back. "And nopony will stop me!" I yell as I use more magic up to teleport me and Nightmare Moon away, leaving behind a stunned set of Bearers and my armor.
