Twilight's eye twitched. "Okay, here's the plan. We build an exact copy of Equestia someplace not being unmade by the invulnerable universe destroying giant. Sound good?" Her eye twitched again.
Dawn looked at Twilight in annoyance. She smacked her across the face with a hoof. "I thought you were made of sterner stuff. You are the element of magic, Twilight, act like it! Don't make me regret the decision to trust you. Look at that monster, tell me what you see."
A mountain to their left ceased to exist. Several stars snuffed out. The moon and sun were nearly fully reformed now.
Twilight's eye was still twitching a bit, but she took a deep breath and calmed herself. She looked at the colossus floating motionless before them. The light struck it... And was devoured. It was not the creature absorbing the light however...
She began casting, summoning a lightning strike from the clouds. It struck the armor, and was absorbed. She watched the process with a Sight spell cast.
Dawn nodded. "Very good, you've noticed it, there is an enchantment on the armor covering that monstrosity. It absorbs magical energy."
"Then how can we attack it?"
"Um... Girls, I hate to complain but Shimmer and I can't keep this up for much longer and-" Fluttershy was cut off suddenly as her concentration was broken by a large black hand sideswiping her from the air. Shimmer immediately broke eye contact and plunged through the air after her.
Omega laughed. "Fools, did you think you could keep me immobile forever? I'll unmake you next!"
A loud blast sounded. Pinkie had fired a weapon from the distance, a baked bad flew through the air and exploded on impact. "The Cupcake Cannon MK2! Prepare to be assaulted with the worst baked items to ever have graced an oven!" She fired again.
From the opposite side Lokey, comedy mask in full relief, had somehow cloned herself into a pony with an a poofy mane with a bald spot, a bald pony, and a pony with a head of black hair which looked like it had been cut around a bowl. The three clones were chucking pies from a table floating next to them for no apparent reason. "Hey knucklehead, catch this!" The pies arched in the air and burst into flames on impact.
Pinkie laughed. "Exploding lemon meringue. Good one!"
Rainbow had been watching the exchange of Dawn and Twilight, she hadn't had much to say while the eggheads talked magic, but she thought she could offer an opinion now. "How about physical attacks?"
Dawn nodded. "Applejack, Blueberry, you two are the strongest physically. Do your worst."
Applejack and Blueberry swooped up into the air. "On the left Blue!" Making use of the gravity boost they both accelerated just shy of Rainboom speed and flipped at the last possible moment to land two precision kicks in the chest plate. The armor vibrated and visibly showed cracks.
Twilight had been watching closely for magical field variations. "Its hardened against physical attacks. Maybe a precision magical and physical strike..."
Pinkie and Lokey were now spraying Omega's eyes with seltzer water. Applejack and Blueberry attacked the legs.
"Ideaaa!" Everypony looked at Rarity. "Darlings, it's simplicity itself, we need to punch a hole in something that by all rights we should not be able to. I do this at my shop every day! You've seen my designs, I used gemstones on everything, but in order to sew a gem to an outfit you have to punch a hole in the stone to properly attach it. Just before that dreadful incident with the diamond dogs, I made an outfit entirely studded with diamonds. It initially proved difficult, because on every other occasion I had been using a diamond tipped drill to bore a small hole. A diamond can cut another diamond, but the process becomes harder when you lose bits with every attempt."
Pinkie and Lokey had broken into a barbershop quartet, with Lokey singing three of the parts. Pinkie was... Also to the side playing piano.
Applejack and Blueberry assaulted Omega from all sides to run interference, while Pinkie and Lokey... Did whatever they were doing.
Twilight nodded. "You asked me to research a spell to enhance the hardness of diamonds, in return you taught me the spell to find gemstones."
Rarity flashed a grin. "Precisely dear, I say if we can't blunt force our way through, we can drill! I will clad myself in the diamond skin I had during my... Altercation with Sapphire here. Sapphire can do the same, and we can become a living drill bit!"
Rainbow scratched her head. "Okay, but how are you gonna drill? You need something to spin you around..."
Rarity smiled warmly. "I happen to know of a couple of ponies who can make tornadoes particularly well. So, is it a plan then?"
Tornado and Dash grinned.
-------------------------------------------------
It took them some time to gather the gems necessary, in that time Pinkie and Lokey reenacted the pageant of Hearths Warming eve in midair as their clones formed an audience. Still more clones were off to the side pelting the monster with baked goods. Omega swept his eyes and hands about swatting at the clones.
Applejack and Blueberry were taking a breather. Fluttershy and Shimmer returned, the former fully healed after the ministrations of the latter.
The sun shone again in its full glory, and the moon was again adorned with the face of the Mare.
Rarity and Sapphire returned, clad head to hoof in a cloud of shifting sparkling gems. Rarity squee'd. She absolutely loved the way she shone in the light. She turned to Sapphire. "Just like we practiced dear!" Sapphire nodded. She and Sapphire flew at Omega, clasping hooves and using their wings to begin the rotation. Behind them Rainbow and Tornado began crafting a storm more powerful than either had ever crafted alone. Twilight and Dawn fed their energy into the wind tunnel keeping it stable. The storm caught Rarity and Sapphire in its wake and propelled them, spinning them at speeds which made the two blur together into one form.
Omega looked away from the Pinkies and Lokeys assaulting him, and down at the tornado about to strike him in the chest. "What are you-" He felt something cutting into the plate, sheering the metal. "No, this is not possible, I am the end. I am invincible. You cannot do this!"
Rainbow struck a pose, catching a pair of sunglasses Pinkie had tossed her for no apparent reason. "Who the hay do you think we are?"
Rarity and Sapphire burst through the shell of armor. However, instead of finding a body underneath, they found a curious sight. At first Rarity was convinced she was seeing things. However after her eyes stopped spinning she still saw it, albeit without the constant nausea-inducing eye spinning. It was a rather nicely decorated little room, the walls were a pleasing shade of purple, a table was placed in the center, surrounded by four chairs. At the table, there was a silver tea service with a plate of scones. This by itself seemed perfectly normal, compared to the apparent guests to this tea party. Nightmare and Discord, sitting at a table, were eating the scones and drinking tea.
Discord looked annoyed. He finished his scone. "Yes well, no point in bemoaning our fate now, we'll either be destroyed or we won't." He drank the teacup, and tossed the tea to the side, where it became a potted plant.
Nightmare slammed a hoof on the table. She managed to spill her cup in the process. "I don't understand, when I joined with Luna I still had control. It wasn't full control, but I wasn't a prisoner in my own body!"
Discord rolled his eyes. He dabbed up the tea with a napkin and poured her a fresh cup. "Really, you are surprised that mixing your magic with chaos magic produced something neither of us expected? There was a reason this was Plan B you know. I knew we would produce a powerful being when we merged, I had no idea what would result." He held out the plate. "More scones?"
Rarity and Sapphire stood up, Rarity cleared her throat. Both Nightmare and Discord looked at her. "Excuse me, I hate to interrupt, but would one of you care to explain what in the buck is going on? Oh, and do pour two more cups would you? I suspect this explanation may take a moment." Rarity pulled a chair out for Sapphire to sit, and nodded courteously as Discord pulled out a chair for her to sit as well.
-------------------------------------------------
On two separate celestial bodies, two ponies woke from their healing slumbers. A mane of solar flare blazed out from the elder sister. The younger sister's mane now shown with the light of a several supernovas happening at once. Celestia felt her sister's recovery. She hesitated, but decided to use a communication method she and Luna had barred to each other since long before the incident. They preferred to use scrolls under normal circumstances, but she felt Lulu would forgive her this time. She concentrated and sent her thoughts to her sister.
Luna heard her sister's voice in her head. "Lulu, are you alright?"
Luna nodded, then realized this was pointless. "I'm fine now Celly." She looked up the at sky and winced, some of her favorite constellations were bereft of key points of light. "The night sky is going to take a lot of time this evening, I may have to repaint the whole thing."
Celestia heard her, satisfied. She thought back. "Shall we go kick some flank?"
Luna smiled. "Indeed, see you on the surface sister."
Both of them teleported to go meet their friends.
