For the most part, i don’t like images where they add a little wobble and re-uploading it. But this one is pretty awesome if it comes to the animation and additional effects like heat. Let alone the contrast and color.
I have a theory of how we might end up seeing this particular character:
The season finale.
-Starlight changes the past so RD doesn’t make her first rainboom
-Twilight never becomes Celestia’s student nor the Mane Six form against NMM
-When NMM comes, Celestia has no choice but to channel all her dormant power (not the Elements) and becomes Nightmare Star.
-NMS kills NMM and begins a reign of Absolute Day. She singlehandedly destroys future threats particularly Discord, Sombra and Tirek (Chrysalis doesn’t even show up as there is no wedding or she is dead due to the lack of love since no one is happy)
