I present all over the world, Midny Sparkle. The physical form of the remantens of Midnight Sparkle.
 
Synopsis:  
On an excursion to some crystal caverns, Twilight was attracted by a strange gem that shone brightly, when touched, the remnant of Midnight Sparkle’s consciousness separates from Sci-Twi; taking physical form. Reincarnated Midnight causes chaos in Canterlot City until Twilight and her friends intercede, realizing that she is not furious, but confused. Twilight hugs her to calm her down and when the corruption wears off a copy of Sci-Twi with different hair and eye colors remains. After a few days, Midny wears a different hairstyle to be differentiated from the one that she now considers her sister, since she is ultimately adopted by the Sparkle family.
