Ch.7: Dark Moon's prophecy part 1

With Marco all healed up thanks to Star she rose up to her feet. For some reason though Marco's left eye felt itchy but he set that feeling aside.

"Marco, now that you're healed up I want you to get my mom and Globgor out of here."

"Says who? I'm not gonna be outshined by my own daughter twice."

"Mom!...You got jokes now?"

Moon was up and about, standing next to her own flesh and blood.

"One needs to have a little sense of humor in their life. That's what you've always told me sweet heart. Although I feel like I'm in my wrong attire?"

"You think? That armor is so old season."

Moon couldn't help but chuckle from the joke. Though Star was right, the armor she was wearing was a bit outdated for her kind of current taste.

"Then allow me to slip into something more comfortable?"

Taking a deep inhale and then a sharp exhale, Moon instantly changed into her Mewberty form like Star was.

Sprouting big light blue Butterfly wings that had the pattern of diamonds from her back, bluish skin, 4 more pairs of arms appearing, and her new royal armor with her diamond cheek pattern imprinted on the front. The sense of complete preparation put her mind at ease.

"So you're telling me to run away while you two risk your lives to defeat Nebula?"

Marco was definetely against this plan. He couldn't explain it but he could feel somehow that Dark Nebula was more powerful than he was letting on.

"I understand that this plan is stupid, But if Globgor were to die? I would be sad and Eclipsa would be devastated."

Star shook off the negative scenarios that were swirling in her head.

"Also if you haven't noticed by now Dark Nebula has been standing there patiently. He would've just killed us where we stood yet he didn't."

Gritting his teeth Marco had no choice. He started off walking away slow at first. Then he picked his pace into a run with the wand still in his hand while picking up Globgor's body onto his back like he was two big sack of potatoes.

"You better not die on us!"

When Marco was out of sight both Star and Moon (mostly Star) breathed out a sigh of relief. They still held their intense stares at Dark Nebula, who was removed his cape from his back and letting it fly off to the sky by an intense wind.

"You're damn lucky none of our citizens died from that dark explosion. If there was then we would beat the everlasting s*t out of you!"

"Young lady, we'll talk about the use of your foul language later. Just because you turned 17 a few months ago doesn't excuse you from becoming more like your father."

"Is this really the time for this?"

"Yes, yes it is."

Dark Nebula cleared his throat.

"...Shall ve?"

As soon as Dark Nebula spoke Star and Moon made the first move by colliding their fists with his face, their strike sent him flying from the impact behind it.

The punches didn't hurt him though.

"Zeph Bunny Rabbit Blast-"

Star kicked her right leg against the air, causing a bunny shaped air pulse of peach colored magic that propelled her to Dark Nebula at high speed. Once she was a few inches over Dark Nebula Star cocked back three of her open palmed right arms. A pink hue covered her palms.

"and Glittery Heart Slap Attack vers.2!"

Star slammed all three arms downward. Instanty a giant sized pink glittery heart smashed Dark Nebula into the ground. It's intense gravitational pressure drove his body deeper and deeper into the ground a few feet until it evaporated, creating a large heart shaped hole.

"He's definetely not down. This'll give me time to charge for a couple of seconds."

Star enclosed her the top two hands until they were an inch apart. Electricity was eminating from both hands.

From inside the hole Dark Nebula was smiling in an excited manner. To think he would be caught off guard like that...if that was the case that is? He was curious to how strong these new gen Butterfly's were?

"Huuuuuuuu."

Dark Nebula took a deep breath til he was about 50% of his lung capacity. All he had to do was wait for a bit. A rainbow orb formed inbetween Star's hands.

"50% ThermoNuclear Butterfly Bl-"

"HAAAAAAH!!!"

Dark Nebula from the hole released an insanely powerful sonic boom from his lungs and out his mouth. The boom hit Star directly on her head. She felt the light in her eyes turning off and her ears deprived of sound as she was falling.

But she still had her arms. So with a hard painful slap to her temples Star regained her vision and slightly her hearing. It also got her to use her wings to make a full recovery of her disorientation.

This gave Dark Nebula the slight opportunity to jump out of the hole and appeared in front of Star.

"Now let's see? How much strength should I use against you?"

"(That speed?!)"

Dark Nebula was already about to throw a devastating punch at her, not giving her any time to react.

"How about this mu-"

Dark Nebula felt a slash at the back of his armor. Moon came at the right time before he could go through with it by using her Light Sword Spell.

"Star now!"

"(What?)"

Dark Nebula looked down to see Star perfectly aiming the rainbow sphere formed from 4 of her arms point blank at his stomach.

"You seemed overconfidant with your abilities. So we took that chance to distact you so I can hit you with this."

"(You're kidding me? To think I vould-)"

"80% ThermoNuclear-"

"(-Make a mistake that vasn't on purpose this time?!)"

"BUTTERFLY BLAST!"

A humungous rainbow blast engulfed Dark Nebula all the way out of Mewni's atmosphere and onto one of the moons. The impact caused a grand explosion that formed a rainbow colored mushroom and cracks along the surface.

"Phew haah I think that done it."

That would be the case from Star's perspective. But Moon felt something off? With the Lightning Sword Spell still in hand Moon sensed an evil presence, prompting her to quickly turned around and block a midair axe-kick delivered by Dark Nebula. The ground underneath her caved in, creating a crater.

"Are you kidding me?! That was shot point blank yet he didn't get hurt?"

"Rrgh ggh I figured he was strong but not this strong? You probably should've used 100% of that."

Moon swiped her blade knowing that he was behind her, knocking away Dark Nebula as he landed on his feet like gravity doesn't affect him at all. After a few seconds of silence Dark Nebula started to clap slowly.

"Ah yes, very impressive feats of power."

"You're one tough cookie aren't you? Not even a single scratch is in you."

Dark Nebula stopped clapping.

"That's not true, see?"

He pointed at the stomach area of his armor to show that it recieved a slight dent.

"You dented my armor. That never happened to me except for that one fight with Zeus himself. That doesn't matter now, ve should just get started vith removing our kiddie gloves."

Moon and Star looked at eachother and then sighed. They didn't think he would figure out their bluff this easily either?

"Okay okay what gave it away?"

Star joked a little (although this was suppossed to be serious) while putting all her hands on her hips with a smug look on her face. Just by the way she was looking at him Dark Nebula felt this weird flash of someone doing that same exact pose, except with lesser arms.

"The beginning when you transformed into vhat you are now. Come now did you honestly think that I didn't sense that you two were only using 15% of your power?...Though I vould be kinda guily since I used less."

"Figured as much. Looks like he's not gonna fool around anymore. Ready Star?"

"Yeah, get ready Dark Nebula cause now the gloves are off now."

"I don't understand? What do you mean by 'events, determined'?"

An hour after everyone except for River left the castle, this strange being that no one noticed was sitting across from Eclipsa in a strange awkward manner. Meteora wanted to look away from it's appearance yet she couldn't. All she could do was sit on her mother's lap, shaking like a leaf.

"Events...d-determined *twitch*...Rise t-t-t-t-to...Dark Moon."

Eclipsa was trying to make sense of this gray, leathery skinned creature who's head was twitching slightly like an insect. It's raspy, choked up voice sent shivers down her spine. With that cloth covering it's eyes she defenetely didn't want to know what were underneath them?

"I swear you look familiar? I just can't put my finger on it?"

Glossaryck was literally an inch away from the creature, scratching his chin and squinting his eyes.

"Please good...monster? You told me that you came to give me a warning? What do these 'events' mean and what about this Dark Moon?"

The creature placed its hands on the table top.

"Dark Moon..."

"Yes, what about it?"

"...Dark Moon m-m-m-marks end...of the...world."

"I'm pretty sure we met somewhere before? Hmmmm Strip Club maybe?"

"Glossaryck?! Now's not the time for fooling around. Also Meteora is right here you know?"

"Oh sorry sorry. Anyway I was gonna leave since Star is about to call me for my assistance soon. Hey pal could you at least tell me your name before I go?"

Glossaryck could see that the creature was physically straining itself. It kept turning it's head in different directions.

"Okay stop, no need to strain yourself. Toodles your majesty."

With a snap of his fingers Glossaryck vanished, leaving Eclipsa and Meteora with it.

"End of the world? That can't be right? Star, Moon, and Marco are fighting Dark Nebula."

That name caused the creature to drive it's clawed hand into the wood with a crack and claw towards itself until its arms drooped to its side. That startled them both.

"Nebula...won't d-d-die. Moon...will...die."

Eclipsa, Meteora and River who was nearby were all shocked by this creature's words.

"What? Poppycock, my wife won't lose to some weirdo in a cloak!"

River slammed his fists on the table, startling the creature. It's breathing quickened while it turned it's head away, covering itself with its hands in fear.

"River, you startled it. I know this is a shocking allegation but at least hear it out? I'm so sorry, please continue."

The creature instantly calmed down.

"Darkness...win. But d-d-darkness...lose. Too late...for..kin..save another."

"(I think he means Dark Nebula wins. By god.)"

"Fate...change."

"Wha?! How? How can this event be stopped?"

The creature got on the table and skittered like a bug. It's face was close to Eclipsa's, all in a swift motion. Both Eclipsa and Meteora pressed their backs against the seat.

"Trust...in...meee."

That was strange cause Eclipsa could've sworn that the creature was trying to sing.

"Trust..in..meee."

The creature repeated those words. It's voice seemed to have become clearer yet still raspy. It was until the third time.

"Trust in meeeee."

--

Marco was able to make it back to the castle with Globgor except he was awake now so he didn't need to drag his heavy body. He just felt numb in the leg so Marco had to support him up.

"Son of a bitch. I can't believe I was useless again!"

Marco settled Globgor in a chair in the main lobby.

"Hey hey hey don't beat yourself up over this. I couldn't do anything either. But since we're back in Monster Castle we can live another day."

"You don't understand? This is the second time I couldn't protect someone from danger. God I feel so goddamn useless."

Globgor hung his head low with a frustrated sigh.

"What the hell are we going to do if Dark Nebula comes back here and tries to kill my wife...in front of me?"

"That's why we're back here? To be the last line of defense for the current Queen of Mewni."

"Yeah but if that does happen and he does get here? Are you willing to go through the possibility of your friend and Moon being dead?"

Too be honest Marco really thought about those possibilities. But he already realised from that battle with Toffee that no matter how grim the odds were, Star would always come through in the end.

It was strange though? Ever since Star told him to leave with Globgor, he's been hearing voices in his head...voices like Star's and some others he didn't recognise and his left eye was itching like crazy. He couldn't explain both of these sensations at all and why did he feel connected to Dark Nebula?

"Honey?! Is that you?"

From the top of the stairs Eclipsa called out to Globgor. The sound of her voice always riled him up.

"Yes my princess, I'm done he- urgh!"

In pure excitement Globgor tried to walk towards the stairwell. But when he got off the chair he was sitting on his left leg stung him with the painful numbness he wasn't used to, causing him to get on both his knees.

"Globgor! Be careful man, you're still recovering from that explosion."

The moment Eclipsa went down the steps she just heard the word "explosion".

"Explosion?..."

Marco could tell from Eclipsa's neutral expression that she was pissed. It took only a year to see the signs, like that dark cold look in her eyes.

"Rainbow Multi-Punch!"

Star was throwing punch after punch with her six arms, firing one rainbow fist after another while dodging Dark Nebula's red beam attacks.

Moon was contributing by using her Neon Whip Spell to try and and make him slip up. But his footwork was way experienced than she could imagine.

Dark Nebula pressed his foot down with excellent timing, trapping one of Moon's whips under. He then gripped it with one hand and pulled her towards him without any resistance.

Stepping off to the side Moon crashed head first into Star who was trying to attack him from behind when he was distracted. They were both knocked to the ground, rubbing the top of their heads from the headache they gave eachother. Star quickly noticed him in the air with the intent to turn her to mush with his feet.

With a bump on the arm by Star she and Moon dodge rolled away from eachother. But Dark Nebula as he landed he twisted his hip and kicked Star in the face. She was sent into a high flying spiral for a few seconds til she recovered with her wings. Her vision went all wanky when her chin was the one that was struck instead of her face.

"Ohh so close."

Dark Nebula caught Moon's Light Sword from behind without looking. He wagged his finger.

"You really gotta go out to more vars. It can build up some major muscle."

Dark Nebula elbowed Moon in the stomach. He let go of the blade so she could land on her knees while clutching her stomach, coughing out blood.

"Is this really all you got? I expected a little more from the current generation of Butterflies."

With a sigh Dark Nebula rose his foot off the ground and put it on the back of Moon's head, slowly giving more and more pressure. Moon clenched her teeth as the pain became greater. She felt like a grape slowly being crushed.

"Then you expect this!"

Star torpedoed herself at Dark Nebula and tackled him off his feet. She had to flap her wings hard due to the speed in order to soar upward. Dark Nebula just rolled his eyes as he slammed his elbow into Star's back.

His brow rose when he saw that Star wasn't letting go although she felt the damaging impact in which cracked a bone. He did it once again, she still was letting not him go.

A hint of annoyance filled his nerves. Once again he raised his elbow over his head to strike. But suddenly he felt his body being released, falling slowly at first.

"Vooow a planet level fall to the ground? Sooo original. Do you know how many planet level falls I've had and still lived?"

It's like these idiots are really scraping the bottom of the barrel and made a desperate, hail mary attempt to disable him. Dark Nebula knew that he would survive it so he just thought about humoring them.

He only escaped from a fall from space with a few bruises a couple of times in the past yet he was still kicking over to the next fight with no complaints.

That is until he looked up and saw Star's eyes glowing gold and her body enveloped by a gold sphere with the heat of the sun. Sensing her radiant magical energy felt alien to him.

"(Vhat the? I've never seen a spell like this before? Hmm doesn't matter, I'll just-)"

Dark Nebula sensed something else from below, an enormous amount of a different magical was eminating. Moon, who recovered from the attack had her eyes closed while concentrating on gathering as much magic as possible.

"This may not be my strongest spell. But it is gonna be enough to beat you! Ready mom?!"

Moon was at the right output to "use it". Somehow she was able to hear Star's voice.

"Whenever you are sweetheart!"

Star opened all her arms out, each of them conjuring gold spiraling orbs of her magic. She then pushed them all towards the center, quickly fusing them together into one. Moon shifted her positioning and posed herself like she had a bow and arrow. An invisible, silvery misted glitter arrow formed as she pulled her arms back, forming also a light blue string.

"You son of a bitches! You both vere still holding back on me?!"

"Sorry but it was your cockiness that made this work. So let us show you what we got! Star Butterfly Special: Super Monarch Justice Blast!"

Star fired a ginormous gold ray of magic. At the same time Moon exhaled and released her fingers, letting loose the arrow.

"Stardust Grand Arrow!"

Dark Nebula just now realised his mistake of fooling around with them. Thinking that this would be a warm up for his conquest, treating that princess like she was a walk in a park...He's experienced this before?

It's not all that bad though? He can just simply dodge them with the exerted effort of his speed this time. Before he could however he found himself surrounded by silver and gold light, floating in its weird space.

"This energy...Vhat the hell did they do?"

Outside from his perception he was inside of a moon sized globe of silver and gold. From the air Star floated downward and touched her feet on the top of her and her mother's own creation.

"MOOOOM! CAN YOU HEAR MEEEE!"

How could Moon not hear her? Star wouldn't need a megaphone to call someone, even from space.

"YES I CAN!"

"GREAT! I GOT ENOUGH MAGIC TO FINISH ANOTHER OF OUR TEAMWORK TECHNIQUES! STAND BY AND SHUT YOUR EYES!"

Moon did as she was told while Star kicked herself off of the giant sphere. She then clapped her hands together.

From inside the space Dark Nebula looked down at his hand. It was slowly being enveloped in a gold light. His hand wouldn't move no matter how hard he tried?

"Vhat is this magic? It, it burns like hell!"

Star modeled this giant sphere after a spell she encountered when she was younger. Dark magic would corrupt her Mewberty form so she had to think of another way and it took an enourmous amount of magic to produce it.

So a year ago when Star and Moon went on a journey to get stronger than ever she came up with some ideas for a new concept called fusion spells. It took trial and error but eventually they were able to work in synch for these kind of spells that held enormous power behind them. Star was now paying homage to her kinda grandmother.

"Gold Velvet Inferno!"

The giant sphere started to rotate, it's speed was increasing more and more all the while white light encased the entire outer surface of it. After a few seconds the sphere imploded itself with a gold flash. Cracks appeared all around the sphere until it shattered like glass.

Being slightly more exhausted than usual as expected Star softly landed on the ground. The moment her feet touched the ground she instantly got on her knees and heavily wheezed.

"We wheeze haah haah did it for real wheeze pheww oh god my back."

Moon knelt at Star's side, caressing her back.

"I'm so proud of you dear. So so proud of you."

"Heheheh thanks Mama."

Falling from the sky, thought to be dead the light in Dark Nebula's eyes were gone.

"(Today vould make 3000 years...3000 years that I've never been beaten in battle. Vell except for Celestia and her Magic High Counsil. They vere able to kill me and spread my ashes to a part of the universe as...Nebula.)"

A big crack formed on his armor.

"(But not before cursing me in case I ever came back to life that sealed my soul, my body, and my mind...along with my magic but that's not the point?)"

His arm gauntlets and leggings were blown off, revealing darkish red furred monster arms and whooved legs.

"(Those fools never realised why this armor never broke in the first place? Only Celestia and her has witnessed the entirety of my original curse, the Wrath of Capricorn. If I were to ever to get even a tad bit angry without this armor keeping it asleep, death would occur.)"

Both the cape and the back armor were blown off as well revealing his strong red furred back.

"(Sorry honey, I couldn't keep my promise nor keep the curse in check anymore...now this world and the ones beyond that will be destroyed.")

As the front armor was shattered the color in Dark Nebula's eyes returned. Above him a blackened circle appeared the sky, emmiting an ominous purplish glow.

"(By Celestia...I feel like a monster.)"

His right eye's iris changed to crimson but his pupil were horizontal and rectangle shaped.
