Yes i am well aware that this is just an inverted color scheme of rainbow dash's cutie mark but that is the point nightmare manacle is rainbow dash but yet at the same time is a completely different entity.
"THIS WORLD IS FILLED WITH NOTHING BUT BACK STABBERS! SELFISH PONIES DOING THEIR OWN SELFISH THING AND ONLY HELPING OUT WHEN IT SUITS THEM! WELL LET'S FIX THAT NOW SHALL WE-?!" Hissed the Nightmare with solid white eyes. "ONCE EVERYONE'S CHAINED TOGETHER YER GONNA HAVE NO CHOICE BUT TO LOOK OUT FOR EACH OTHER YOU BUNCH OF LOSERS!"
A home made grenade, not a pie, not a cake, but a very real hoof held -bomb- exploded to one side of the gray and inverted colors Nightmare's face.
"YOU NEED TO CALM DOWN AND LAUGH IT UP DASHIE!" Pinkie Diane said carrying a satchel of hastily constructed weapons. "You're making everyone miserable!"
"THERE IS NO 'DASHIE!' I AM NIGHTMARE MANACLE!" Eight chains sprung from the Nightmare coming down towards the Earth pony from all sides who agilely dodged the attack.
"PINKIE LOOK OUT!" Screamed Mr. Cake's voice as he came up from behind her with a meat cleaver. It cut off part of Pinkie's mane. The chains pulled the stallion's forelegs back for another slash. He was wearing a badly fitting Shadowbolt costume.
Fluttershy/Fluttercruel dove down to try and get at her from above but instead were too busy dodging rainbow colored lighting bolts.
"GOTTA PROTECT DASH! GOTTA PROTECT DASH! GOTTA PROTECT DASH!" Shouted Scootaloo like a broken record. She was moving too fast for Rarity or Twilight's telekinesis to catch her as she ran interference for the Nightmare. Scoots was wearing a Shadowbolt costume with chains around her neck and hooves.
"We've got to pull back!" Rarity shouted. "Get Celestia and Luna!"
"We can't abandon Dash!" AJ shouted.
"We're not abandoning! We're getting help!" Rarity protested. "If we get the Elements then maybe we can actually do something to save her!"
That was when Applebloom and Sweetie Belle from their hiding places jumped and grappled Scootaloo from two sides. "GOTTA PROTECT DASH! GOTTA PROTECT DASH!" The chains on her hooves snaked to life and wrapped themselves around Applebloom and Sweetie's necks. Their eyes bulged as they began to cough up the words, "Gotta, gotta protect, gotta PROTECT-"
"NO!" AJ and Rarity shouted as the costumes began to appear on the two fillies.
