King Sombra; now having just came back from being defeated; decides to go get his revenge once more at the Crystal Empire… , and decided to go even further as to rule over all of Equestria as well.
It worked out for him… . Right up until the end that is… ; when Twilight and her pals showed up and defeated him once more… . Hopefully it was permanent… .
Queen Chrysalis, Tirek, and Cozy Glow; have just defeated Discord… . And are just about to drain all the magic from him again; when suddenly he fled. Having no other choice; they just let him be, and then laughed maniacally together before setting out to go and get their revenge on Twilight Sparkle… .
However; just before they could… ; as if it’s like some Marvel’s Avengers scene; (patent pending); everyone from everywhere in Equestria has arrived, and helped defeat the villains once and for all.
All the villains except Discord since obviously he’s not a villain anymore… but a reformed one… .
Soon after the battle; Twilight and her pals say their final goodbyes to each other, and then separate for what could possibly be their final moments with each other… .
However; what everyone doesn’t know is that the villains are not so defeated as they thought they would have been… .
How will the ponies react to this… ? They’ll have to find out once they return… . And oh boy will the villains return… with a vengeance possibly… .
