Demons of the Night.

Summary: Dipper… a boy with powers far more respectable than anything we've ever seen. But something dark lies far beyond his awkward yet solemn nature… And Mabel finds out far too late that even the ruler of the night has demons.

Rated: K+

Day once again shone on the town of Gravity Falls, courtesy of Mabel. But tonight, Dipper dreaded this night for a while.

Tonight was a blood moon.

While these were rare in the world of Gravity Falls, Dipper had feared this moon for years.

It was when… he… came out of hiding and showed his colors.

Dipper was currently walking into the dining room where he and his respected twin were gathered to discuss the dinner party they (meaning Mabel with Dipper being dragged into this) were setting up with the other rulers of the other realms.

Stan was also helping- by trying to find the best objects for the cheapest cost. The great uncle lived with the twins ever since their parents passed away, and he was a great solace- even though he loved money.

"Mabel, you better have a good excuse for waking me up this early." Dipper gargled out, trying to rub the sleep from his eyes and remove the cold water from his mouth. Mabel asked for him and Grunkle Stan did it in the best way he knew how- by dumping cold water on the boys' head.

"You were asked to oversee stuff for the dinner party, remember, Dip?" Mabel repeated.

"I did all of that yesterday. Can I go back to sleep now?"

"Nope! Not until you look over all the new stuff I got!"

Dipper sighed and shuffled his way over towards the table, looking over all the new items that Mabel and Stan had bought and forced him to respond.

"No- No- No- Where did you even get this?" Dipper inquired as he held up a beautiful gold ribbon that was several yards wide.

"From the hundred dollar store."

"Uh-huh. I'm done. Back to sleep for me." Dipper replied a little too quickly and marched his way to the door, almost missing his sisters response.

"Dippster, you've been sleeping a lot more than normal… what's wrong?"

"I'm fine." The prince responded nonchalantly.

"You sure? I mean, you've got bags under your eyes, you've been a grumpy-grump pants more than even Stan, and-"

"I said I was FINE, Mabel." He growled, much more coldly then he had wished. Mabel backed away in slight surprise, and even Stan's eyebrows shot up in shock. With that, he opened the door and quickly walked away.

"Welp, something's wrong with your brother." Stan stated the obvious. "You should talk to him after the dinner party."

Mabel sighed, not noticing Stan getting concerned for the boy, as he knew something and he was praying hard it wasn't what he thought it was. "You're right as always, Stan. I'm gonna speak to him and see what's going on in that cray-cray brain of his."

Mabel went off to her royal decorators for the party, leaving Stan in the opened room with the stained glass windows. He looked particularly at the one where Dipper was portrayed as Nighterror Nebula. It would have been beautiful, with the intricate patterns the people made, but Stan looked upon it with a dark look in his eyes.

"Not tonight, kid. Not tonight. Please Dipper, fight it."

The entire dining hall was grand with large, stained glass windows and red ribbons. Banners portraying Day and Night were in strategic locations, and flags from all the different regions were along the pillars by the walls.

When the guests from the other areas walked in, they marveled at the beauty and wonder the twins created in a day. They took their seats by the long, marble table with a deep red table cloth, gazing at the large array of food spread for all to share.

The wide double doors opened, revealing both twins in a finer form.

Mabel's normally short white dress was slightly longer, reaching to her ankles, which were graced with golden sandals studded with amethysts. Her long, flowing chocolate hair was done up in a bun, traced with blue, green, purple, and pink streaks.

Dippers deep blue robe was replaced with a slightly darker colored toga, with a silver sash draped gracefully over his shoulders. His crown was slightly more pointed, and his short silver gloves were replaced with slightly longer ones with spokes, pointed to look like a trident. His cape became more lavish in size and details, looking like stars in the night sky.

"Hello everyone!" Mabel addressed. "Thank you all for coming to this super awesome event!"

"We come bearing glad tidings to thou!" Dipper replied, using his royal palace voice. He was so excited that everyone was here that he forgot to lower his booming speech. "We hope thy will enjoy-"

"Uh, Dipper? Tone it down a notch." Mabel whispered.

"Oh." Dipper replied normally, his face flushing slightly red with embarrassment, noticing the people were slightly surprised at the sudden change in the boys tone. "R-Right." He cleared his throat, and tried again normally.

"We hope you all enjoy the party and have a great time!" The flabbergasted people stiffened less and began to relax and chat with each other about the food and other royal events. Dipper and Mabel took their seats on the silver and gold thrones at the end of the table, each to their respective chairs.

There was hardly an incident with anyone after that (except for the small scuffle over who would get the last brownie. Dipper swiped it while everyone was arguing), and overall everyone had a good time. The only major problem arose when a leader asked one of the twins.

"Is it alright if we see Dipper raise the glorious moon to bring forth the night?"

Dipper had to relax himself after he nearly choked on his slice of pie, his fears for tonight aroused once again. To his horror, multiple others agreed.

"Sure! Bro-bro, you know what to do." Mabel cheered, slapping her brother supportably on the back. Dipper quivered slightly as he stood up and walked towards the window, every step feeling like cement blocks on his feet. He took a deep breath as he spread out his hands and wings, his digits slightly glowing a silver blue. Soon after, the glow reached the sun, surrounding it like a ring. He felt his power work and flow as the sun was set and the sky turned beautiful hues of pink and orange. The leaders gasped in great surprise and wonder, staring at the calming patterns.

With a surge of effort, Dipper raised the moon, the reds and yellows replaced by the white and navy of the night sky. What he feared was yet to come.

He sat back in his seat, the leaders applauding for the beautiful spectacle, and with a sigh he didn't know he was holding, he tried to relax.

He couldn't.

A gnawing feeling was growing stronger by the minute, and as much as Dipper tried to suppress it, it just kept coming back. The moon, he realized, was slowly turning a bright red. He stood up immediately, drawing the attention of a few leaders.

"Prince Dipper, is something wrong?"

Dipper, not knowing what to say, just responded with a quick "I'm fine, just I need to be alone for a minute." Before he raced off towards the doors. Mabel stood up slowly and turned towards the guests.

"My brother probably just wants a little privacy. He never did well with crowds." The leaders murmured a little, but eventually agreed. Trying not to be too obvious, Mabel made her goodbyes and then raced towards her brothers room.

When she opened the door, what she saw shocked her.

Chains were all over her brothers bed, and poor Dipper was struggling in a pair on his comforter.

"Oh my gosh, DIPPER!" Mabel shouted before running over to her brothers side. "Who did this? I'm going to make him pay!"

"No, Mabel, I did this! Go! I don't want you seeing this!"

"Dipper!"

"Mabel, it isn't a request! GO!"

"… No. I'm not leaving. Not until you tell me what's going on!"

"… I'm sorry…" Was all Dipper said before he did something that shocked Mabel to her core.

Firstly, Dipper stopped thrashing all together and stared at the celling like it was something he never seen before. He screamed in agony and knelt down on his bed, His dark blue wings turning a black color, sheading his feathers in replace for something that looked like bat wings.

His teeth grew sharp and pointed, and a small point protruded from behind. A long, whipping tail with an arrowhead on the end lashed around. Dippers hair gave in to a more reddish tint and small, curved horns poked out from under his head. His skin became black as night and his eyes turned golden red.

Dipper, once the Prince of the Night, Ruler of Darkness, once vessel to Nighterror Nebula, was now a demon.

He whipped in Mabel's direction, screamed in her face, then ran out onto his balcony and flew into the night sky.

Mabel had her heart pounding. That was certainly NOT her brother. Not anymore.

She shook her heads and cleared her thoughts: Dipper transformed into a demon. Who could she go to without sounding crazy?

Stan.

The word rang around in her mind as her feet carried her to her great uncles study. She practically leaped into her uncles arms and began random babbling about what happened.

"Whoa, whoa, kid, slow down!" Stan said, watching in shock at what could've upset his great niece so much. "What's wrong?"

"Dipper.. a-after the p-party, I saw h-h-him in his room, and, and there were chains everywhere, a-and Dipper just turned into a d-demon, and I-I-" She couldn't finish as the tears she pent up were released in a sudden shower.

Stan was surprised, yet saddened. He knew this day would come, he just wished it wouldn't be so soon. He tried calming her down shushing her and rubbing her back like her parents used to.

"Kid…" He started, trying to find out the best way to say this without looking like the bad guy or upsetting the child further. "…I've always known."

"W-What?" Mabel looked up, tears staining her cheeks, which just made Stan's heart break.

"Sweetie, your brother is a very… unstable boy. Ever since he was five, he started turning much more aggressive around a blood moon. He started showing signs of being a demon- his wings suddenly turned leathery, he grew fangs, and on rare occasions, turn demon entirely. Your parents and I were the only people who knew about this, and we tried to help him as much as we could. He never had a incident… until now."

Mabel sniffled, trying to process this information. Honestly, she was terrified- not of the fact that her brother was a demon, but the fact that she couldn't help him.

"O-Ok…" She managed out. "I- I wanna help."

Stan smiled warmly. "Alrighty kid, here's the plan."

Dipper was flying over the town, searching for food. He was hungry, and his… other side… wasn't helping out.

'Feeeeeed meeeeee…' It hissed. Dipper roared, and landed squarely in town, intent on spreading panic, which he feasted on.

A woman screamed when she saw him, and the others woke up seeing not a normal animal but a creature of darkness. Soon, the once quiet street was a riot of people trying to get away. The calm night air was split apart by the screams of the terrified and the sound of windows and shutters flying open and close to see what the commotion was about. The demonic side of him loved this feeling, but the original Dipper was horrified.

The looks on the peoples faces… all of them screaming in fear… it reminded him all too much about his time as Nighterror Nebula.

"Yes…" Demon Dipper hissed, his voice sounding snakelike and crackly. "Run… run away, puny humans! Let me feast on your fear!" He opened his claws and slashed at a person roaring to incite more panic.

"M-Monster! Monster!" One person shouted, which just made the original Dipper break down inside.

'Monster…' He thought. 'They… They think I'm a monster… M-Maybe everyone's right… I- I don't deserve to live…'

"Hey ugly!" A familiar voice sounded out, snapping him out of his pity party. Mabel was flying up high with her big, white wings, with Stan hanging lopsidedly by her legs, holding something.

"Look everyone! It's Princess Mabel! And some weird old man!"

"It's MR. PINES, to YOU!"

Besides Stan's outburst, the once petrified crowd cheered whole heartedly, making Mabel all the more aware that the people didn't understand the monster was her brother. She tried to put on a brave face as she responded.

"Catch this!" Stan tossed something at Dipper- a net. He hissed coldly and easily dodged it.

"Aw, we missed!" Mabel shouted at no one.

"Get me closer! I got a plan!"

Mabel nodded, and flew down close to the ground as Stan grabbed the net and rolled to the ground. He stood up and quickly dusted himself off. He stared at Dipper who stared straight back.

"Listen Dipper, I know you're in there! Fight it kid!" Stan's words made the demon halt for a minute, then suddenly rock back and forth.

'Give me my body back!' Dipper mentally screamed at… well, himself.

'Never!' The demon fired back.

'What your doing is wrong! You shouldn't be hurting innocent people like this!'

'But these people wronged you! The ignored you, and now you want to defend them?'

'They might have wronged me, but that never gives me the right to hurt them!'

'HA! You're even more stupid then I thought!'

'Am I?'

Out loud, the demon inquired 'What?' dumbly before getting tackled by Stan and entangled in the net. The demon Dipper, refusing to be caged, clawed and shredded at the net, but it didn't even break a fiber. He seemed to only calm down slightly.

"Strong steel." Mabel smiled. "Come on, bro-bro, let's go home."

Stan had refused to let Dipper back home until he was fully reverted, so he offered to take Dipper to the one place he felt comfortable in.

It had taken a lot of pleading, a lot of pushing, and just the smallest bit of swearing, but Mabel finally relented. She raised the sun, so Dipper could revert back quicker.

When he did, his eyes fluttered open, and what he saw was his crush.

"GAH!" he screamed, and he shot up like a firecracker was under him. Wendy only laughed hilariously at this.

"HA HA! Sorry Dipper, but you should've seen your face!"

Dipper groaned and felt his head, looking around a little. He wasn't in his room, evident by the lack of the big black splotch with a white moon in the middle on the covers.

"What happened? Wha…? Where's Mabel?!"

"Sheesh, Dip." The red-head laughed. "If you're gonna do that all the time, no wonder you sleep in the day. Mabel's fine, and you're in my room."

Dipper felt slightly guilty at the thought of taking up her house (and, he wasn't going to lie, a small portion of him was ecstatic about sleeping in her bed), but he had bigger concerns.

"I just had the most horrid dream about me becoming a demon and-" He stopped short immediately when he saw Wendy's guilty look.

"Wendy, I…"

"It's ok, Dipper. You lost control."

"Wendy, I am so, so sorry you had to see that. I wanted to tell you, but I was afraid that-"

"Afraid that Mabel and I were going to fear you?" Wendy filled in, much more coldly then she wanted. Dippers eyes lost their hue and became orbs of sadness, making Wendy flinch. The poor kid was much more fragile then she imagined.

"Yeah… I wanted to tell you, when I had more control over my powers, but I…" He faltered on that last bit, his eyes watering slightly.

"Dipper, are you ok?" Wendy inquired the shaking prince of the night.

"Wendy… one of the people in the village said… they said I was a monster."

"Dipper, you are not a monster!"

"But I AM!" Dipper shot back, his eyes on the brink of tears, and his voice cracked and shook, but he didn't care. "I- I hurt so many people, I lost control, and I LIKED doing it. I LIKED all the pain and fear that was spread. I LIKED it. You say I'm not a monster, but I am, and I… I just…"

Dipper couldn't speak anymore as he collapsed into tears and lunged towards Wendy, hugging her in a death grip.

Honestly, Wendy felt… despair. She saw Dipper as the Prince of the Night, ruler over half of Gravity Falls. Now here he was, sobbing hysterically next to her. She realized he wasn't a prince who had everything, but he was a 12 year old kid with a curse he could never shake on his shoulders. He was broken, jagged, and he needed a friend.

"Shh, Dipper don't cry." She tried to comfort him. "There there, shh, everything is gonna be fine."

Dipper stopped sniffling and turned around in his blankets. Wendy, still having no idea what to do, tried to think of what her mother did when she was upset. Just instinctively, she started gently rubbing his shoulders in circles.

Dipper, who was still sleepy from last nights' ordeal, welcomed her hand against his skeletal figure. He quietly drifted off to sleep. When Wendy saw the rise and fall of his chest, she slowly got up and went outside her room. She walked, letting her feet take her to a small window and she looked outside.

It held a perfect view of the castle of the Pines twins, and she often came here to see if Dipper was out and about. Now, she stared at it out of memory, and quoted herself.

'Everything is gonna be fine.'

I AM TIRED.
