A corrupted wedding

"Mares and gentlecolts, we are gathered here today to witness the union of Princess Mi Amore Cadenza, and Shining Armor." Celestia's muffled voice could be heard beneath the Canterlot Caves, as Twilight and Cadance ran into a dead end.

"Oh... We're never going to save him!" Cadance lamented.

"We will! We just have to find............ there!" Twilight cried, as she teleported her and Cadance to an upper platform with an entrance to the surface.

However, three Discorded bridesmaids had other plans.

"You're not going anywhere." They all said in unison.

Later................

"Princess Cadance and Shining Armor, it is my great pleasure to pronounce you-!" Celestia was just about to make it official, until.......

"STOP!!!" Twilight called out, as several ponies either looked shocked to see her protesting the wedding, or simply disappointed in her behavior.

"Ugh! Why can't she keep her nose away from where it doesn't belong?!" "Cadance" complained, causing several ponies to look at "her" concerned.

"I mean, 'why does she have to ruin my special day?'" "Cadance" rephrased it to gain sympathy, while "sobbing".

"Because, it's not YOUR special day, IT'S MINE!!!" Cadance announced, causing several ponies to gasp in shock, as "Cadance" was with them about to get married.

"Wha- HUH?! But how did you escape the bridesmaids?!" "Cadance" asked the two ponies.

Earlier...........

The three Discorded bridesmaids cornered Twilight and Cadance, but Cadance picked up a bouquet and levitated it near the bridesmaids, grabbing their attention, she then tossed it away into the caves.

"I WANT IT!!!" The brainwashed ponies exclaimed, as they leaped towards where the bouquet was thrown.

Twilight and Cadance then made their way to the surface.

Currently......

"Heh. Clever, but you still can't stop me!" "Cadance" boasted.

"I don't understand! How can there be two of her?" Applejack asked the question that was on everypony's minds.

"He's Discord! He imprisoned me in the caverns of Canterlot so he could steal my face and drain my groom's energy away!" Cadance stated to the ponies, as Discord gritted his teeth.

"DISCORD?!" The rest of the mane 5 plus Spike gasped, as Discord gave a menacing chuckle.

"Well I guess the cats out of the bag. Or in this case, the Draconequus is out of the pony." He said, before "Cadance" stood on two legs, grew taller, the Alicorn wings turned into a bat wing and a blue pegasus wing, the hooves turned into a lions paw, an eagle claw, a lizard leg, and a goat leg, the horn separated into a deer antler and a goat horn, as the wedding dress came off, and he pulled off his Cadance face as if it were a mask, revealing his true form.

Discord laughed maniacally as all the ponies before him cowered in fear.

"You madam, are correct!" Discord stated, as he pressed a button as if this were a game show.

"For your fiance shares blood with one of the six bearers of the elements of harmony, making him able to cancel my power. I stole your form so I could get close enough to RIP THE HARMONY RIGHT OUT OF HIM, allowing Canterlot to be consumed by countless chaos! Hah ha!" Discord monologued to the princess of love.

"I won't let you! I'll save Shining Armor!" Cadance threatened the lord of chaos.

"Oh, I wouldn't do that if I were you. Not unless you want to go back to the caverns, WITH NO FOOD OR WATER." Discord threatened the princess, causing her to step back out of fear.

"Ever since I pulled the switcheroo, I've been Discording the captain to be a weak, pathetic klutz. somepony who is INCAPABLE of protecting a capital!" Discord stated to the princess and the ponies.

"NO!" Cadance cried out.

"And, once Canterlot has gone crazy, all of Equestria will turn on it's head! Hah ha ha!" Discord revealed his plan to the ponies.

"NO." Discord heard a familiar voice scolding him, and it made him turn sour.

"You won't." Celestia stated to the spirit of disharmony.

"Get the elements! I'll hold him off as long as I can!" Celestia ordered the mane six to reach the elements, to which they did.

Discord groaned, as he wasn't powerful enough yet to block the exit.

"You really think you can beat me on your own Celly? Without your precious Lu-Lu to protect you?" Discord mocked Celestia, as Luna was nowhere to be seen.

"I don't need help to take you down now! You might have made it impossible for Shining Armor to perform his spell, but now that you have foolishly revealed your true self, I can protect my subjects, from YOU!" Celestia stated, as she fired a laser at Discord, which Discord replied by shooting lasers from his finger tips.

'Please hurry Twilight.......' Celestia prayed in her head, hoping her faithful student will save the day.
