Forgive me if my writing is inadequate to your tastes! Once again, if you enjoy this, yay! If you don't, i'm very very sorry! I suppose this fanfic is just not for you. I don't think I have some kind of excuse to come up with so I'll just shrug and say oops.

You'd be surprise how much someone likes something compared to another who doesn't.

Other then that, everytime I bring in a new character or just bring up any character in general in my story, I like to imagine the Super Smash Brawls theme like:

Dipper rises up to the challenge!

Mabel bounds into battle!

Pacifica swings in her sword!

Or, NEW CHALLENGER APPROACHING!

ALSO, I love both of the twins! Dipper is getting a lot of spotlight, but don't worry about Mabel. Expect great things from them!

ANYWAYS, here we go!

Disclaimer: I don't own Gravity Falls.

"Wrench."

"Here!"

"Screwdriver."

"Here!"

"Alien adhesive!"

"Here!"

Soos kept handing whatever item that his mentor needed. They were currently building one of the drones for the simulations that the students used. After more tinkering, Fiddleford slid out from under the machine. He had soot covering his face and upper body.

He grabbed a rag from a stool and wiped his face thoroughly. Fiddleford knocked his fist on the metal and grinned. Another batch of drones were ready to be used!

"Wow, sir! A total of 200 drones built in three days." Soos scanned them all and his mentor nodded. "Yes! One day, you'll be able to do this yourself with your own apprentice."

The older man stretched his stiff joints, prepared to begin programming the drones. But suddenly, there was the tinkling sound of his crystal communicator. He walked over to the table and pulled off a glove to answer it.

"McGucket, your presence is needed in the conference room. Urgent."

Pacifica then hung up. Said man hurriedly packed up his things and shouted behind him, "Soos! Can you take over while I'm gone?"

"On it, sir!"

Fiddleford saw the younger man already typing away at the panel before leaving. He was proud, to say the least. Ever since Soos was a little boy, he had a knack for engineering. He didn't regret taking him under his wing.

The sound of his shoes clicking in the hall was continuous and fast-paced. He found the doorway to his destination and opened it. There was no one else in the room. Except for Pacifica, who was standing near their large screen radar, along with his friend Stanford Pines.

They seemed to be discussing something quietly. They took notice of the third person in the room and motioned him to come over. Fiddleford stood in front of the large screens as well and the headmistress began to explain, "On January 6th of this year, there was a sudden tremendous increase of dark energy in this area."

She pointed to the location where there was a red splatter among the yellow and green shades. On the other map, it appeared to be where one of Gravity Falls' richer hotels were located. Pacifica continued, "I checked with the manager, but he claimed there was nothing that had happened. No sprout or rift, no monster or demon had been terrorizing the hotel. However, I did find out a particular name that lived there, which was Gideon Gleeful."

Fiddleford scowled at the child celebrity's name. He always had a bad feeling about the boy, now it seemed that he'll be causing more trouble. He asked, "Where is he now?"

Stanford replied, "He wasn't in the room. But as we were going back to the academy, we found this plastered on the wall."

The scientist showed his colleague a flyer, to which he took out of his hands. Fiddleford read over the contents of it quickly. The most eye-catching was 'Gideon's Special Shows Starts Tomorrow Night!' In big and bold letters.

"According to what I know, he should be too wounded to even move. His medications were just recently bought." Pacifica commented.

"Also, if my theory is right, he should barely have any power in his amulet. Everyone in the show would notice that they're getting strangely but quickly tired." Stanford added.

"We'll have to check it out ourselves, but not all of us should go inside." She told them, and they discussed their plans. Stanford wasn't even allowed inside and Pacifica had too big of a reputation. The two looked to their third person and he sighed, "Alright, I'll go in to evaluate the situation."

"Excellent," Pacifica smiled, "Make sure to be extra cautious, and extra observant. Report to us as soon as anything bad happens, we'll be waiting outside."

She left right after, probably to check on her students. The two older men were left to chat. Fiddleford asked, "So how's life been treating you?"

"Fairly. But I am happy that my grandniece and grandnephew are living with us now. Although, my nephew and his wife died, unfortunately."

"I'm sorry for your loss. How are the kids?"

"Fine, fine. They stick to each other like magnets, though. Dipper is learning how to become a Soul Fighter by Stanley and I. But Mabel is just a happy ray of sunshine."

"Sounds fun," Fiddleford's face fell slightly, "There are times I wish I had a family."

"Oh, don't stress it," Stanford playfully smacked his shoulder, "It can give you more pains in your hips than what you already have."

"I'm not that old," The engineer replied, jokingly offended. "but your hair is turning greyer by the second."

"Mine is nothing! Yours is already white!" They chuckled in the empty room before bidding each other goodbye.

Stanford was walking along the sidewalk as he headed back to the shack. As he was turning the corner, Mabel unexpectedly popped up in front of him.

"Grunkle Ford! How was your meeting?"

"Educational." He looked around and saw she was alone. Arching an eyebrow, he asked, "Where's the company?"

She just kicked a pebble and shrugged, "Dipper and Grunkle Stan and my friends are all busy. Plus, Waddles decided to be lazy today! So I'm just going around town to see what's good!"

Ford felt uncomfortable of her being all alone, since it was Gravity Falls. He wished he could stay around for at least a little bit. However, he had to prepare for the performance tomorrow. Although, he trusted her to be able to handle herself. The older man brought out a spare vial of healing potion and gave it to her. Ruffling her hair, he said, "Be careful, will you? If anything bad happens, we'll come running. Also, since humans are bigger than plants, it'll take more than a few drops for the healing potion to be efficient."

With that, he continued down his path, leaving Mabel to venture solo. She gladly did so after stuffing the vial in her sweater. There were cute teenage boys hanging around, practically begging for her flirting. She chose one out of the many and started her quest.

"Nice to meet you, I'm Mabel!" She smoothly greeted, but the boy just looked at her weirdly. She waited for him to respond, but none came.

"Oh, I see. Do you have a name? Or can I call you mine?"

Her eyebrows were going up and down repeatedly as he was seriously getting freaked out. He started to slowly back away until he bursted out into a sprint. Mabel snapped her fingers in defeat but looked around. There were still some more to try!

"Do you believe in love at first sight, or should I walk by again?"

"I hope you know CPR because you take my breath away!"

"On a scale of one to America, how free are you tonight?"

No dice. In the end, she was sitting on a bench as other guys now avoided her. The ones she tried to hit on probably told them about her. She glumly looked at some of the young and happy couples that were walking around the park. But then, Mabel caught a familiar figure of yellow and black that was hiding behind a tree. He seemed as if he was prepared to do something, something bad.

Bill Cipher grinned mischievously and rubbed his hands together. This couple wouldn't know what hit them! The guy was about to propose, but the dream-demon planned to insert the wrong name in his mind. Then, the girl would hate the guy's guts. There would be a huge argument, and maybe some violence! It will be hilarious!

Just as the man reached into his pocket for the velvet box, Bill suddenly felt himself fall forwards to the ground roughly. He was exposed to the couple who were stunned to see him.

"GLOMP!" Mabel shouted in his ear, as she was sprawled over him. He hissed at her and tried to push her off, "What the heck are you doing?! Get off! You're going to ruin my fun!"

But it was too late. The couple yelped and ran away in fear. They watched as they disappeared out into the distance. Bill quit struggling and limply laid on the ground with a huff. She sat on his back as he blowed locks of blonde hair out of his face. Before he could stop her, she grabbed his top hat and placed it on her own head.

"Hey!"

She pouted, "Don't "Hey!" me! It's been such a long time since I've seen you, where have you been?"

He rolled his eyes at her concern, "Where would I go? Why do you care anyways?"

She gasped, "Why? Because we're friends!"

He turned his head around to give her a deadpan stare. His fingers itched to burn her face off but it didn't seem all that fun as it should be. She was smiling brightly while throwing out her arms for exaggeration.

"You know, buddies?"

Stare.

"Pals?"

Stare.

"Chums?"

Stare. She scrunched her face in irritation, "Stop with the staring!"

"Then stop with your naivety! We aren't furr-ends." She giggled and he glowered at her. "Now what?"

"That isn't how you say "friends", silly. Come on, say it with me, "friends!" Connect the syllables!"

"It seems you are still deaf, as well as dumb. I pronounced it correctly! Ferr-ainds." She rolled off of him, still wearing the top hat. The brunette crossed her arms with a shake of her head.

"That's even worse! Why's it so hard for you to say it right?"

"I am saying it right!" He fumed defensively, "And it just isn't a word I have much use for, so I don't bother with it."

"What? That's crazy! Of course you need to have use for friends!" She replied incredulously. He furrowed his eyebrows and asked, "Why?"

"Because friends are necessities for life!"

"I'm immortal, Shooting Star. I don't need any of your "frands" to help me live." He grinned haughtily, absolutely sure he pronounced "friends" correctly this time. Mabel clicked her tongue in disappointment, "You don't have to be shy about it, Bill. It's obvious you've never had friends before!"

The dream-demon began to speak, "I've had some before—!"

"So, I'll be your first one!"

She cleared her throat and stuck out her hand for a handshake. "Hi, I'm Mabel Pines!"

He pushed her hand down and snatched his top hat back. Glaring, he spoke scornfully, "And now I'm leaving, bye."

He vanished in a blink of an eye. She just relaxed against the tree trunk and smiled. He must be so happy to have a friend now!

The other couples didn't seem so bad anymore as she hummed softly to herself. But then, she started to rub her arms. It felt like it was getting a bit chilly.

"Why, if it isn't Mabel!" Gideon called out to her, and suddenly her joyful mood went down the drain. The air was ominous and alarm bells were ringing in her head, telling her to run as he strolled over to where she sat. She silently gulped as he set himself down next to her. Mabel could feel him staring at her intensely. Her side went numb with the cold sensation he emitted as the tension kept thickening with every second.

"So, tell me 'bout yourself." He persuaded after a while. In an attempt to not anger him, she lightly chuckled and replied as best as she could, "Oh, I'm thirteen. I have brown hair… brown eyes… a face…"

Well, she may as well be dead now. But he only giggled and snorted, "You're funny, aren't ya'?"

More silence reigned over them. She couldn't handle the pressure of what would happen next, so she thought up of something to ask. She noticed something peculiar with his outfit, and asked, "Oh, uh, don't you usually have your soul weapon?"

He gave her a look of confusion and she clarified, "The amulet."

"Oh! Right, that." He briskly shook his head and looked away from her shyly. "I'm sorry, marshmella'. It's just hard ta' focus when you're by ma' side, but not in a bad way."

Mabel was confident she already knew the answer, but inquired hesitantly anyways, "What do you mean?"

His face went visibly red and he held a hand to his cheek. "Well, what I mean is… I like you! A lot!"

Suddenly, he grabbed her hands in his own small ones. She flinched at how cold it was, and the hazardous vibes it sent through her spine. "Mabel, will you do me the honor of bein' ma' girlfriend?"

She completely froze. Her mind was shutting down as she tried to process what he had just asked. No, no no no! There was no way she would go out with him! While panicking, she tried to rip her hands out of his clutches. But it seemed like there was no way out of his grip.

"And, um, what if I, heh, say… no?" She hesitantly asked. Gideon's face contorted in confusion, "Why would you say no?"

"It's just a question! I'm always full of questions!" She tried to convince him and he seemed to have bought it. But then he began to answer her question, disturbingly slow, "Oh, well, darlin', you're just outright beautiful. And you seem to shine a bright light I've never seen in anyone. I'd love to have you by my side as my queen."

Suddenly, the grip that he had on her hands became tighter. She winced at the hold as he asked, "Now answer my question, why would you say no?"

Mabel gritted her teeth, this little boy was starting to tick her off. She now ignored her logical thinking of keeping calm and started yelling, "I will not be yours! You're just some creepy ten year old who thinks the world revolves around you! Well newsflash, Gideon, it doesn't!"

Her breath hitched in her throat as his expression became black. He shoved her hands away and stood up abruptly. But before he turned to leave, he leaned in close to her face with a sickeningly sweet voice, "You'll be mine, one way or another."

She watched as he walked away, and felt herself releasing a breath she hadn't known she was holding. Mabel put a hand to her heart as she tried to calm it down. She sat against the tree in critical thought. Gideon seemed way more threatening than before. This wasn't a mask to wear or an image to keep up. It was real evil. What had she just done?

She returned home later that day, feeling worn out by the earlier encounter. Her brother was sitting at the dinner table while getting his hand bandaged by Grunkle Stan. Grunkle Ford was writing down some notes as he kept looking at some other picture. They turned to greet her, and she just walked over to them. Mabel sat in a chair and rested her head in her hands, and the three males noticed her lethargic state.

"Mabel, what's up?" Dipper pried.

"Well, today started out good. I found Bill again and now we're officially friends!" She seemed to be happier when she mentioned this. Dipper arched an eyebrow and her Grunkles scoffed.

"What? The dream-demon actually agreed to be friends?" Stan inquired Mabel, who looked to the side and pursed her lips, "Uh, no… but it was an invisible mutual agreement!"

"Okay, so then what's got you down?" Her brother asked, and she put her head in her arms as she began to explain her confrontation with Gideon to her family. "He had this really freaky feeling to him. Like, more than what I felt the first time I was near him. And then he asked me to be his queen!"

"Yikes, he's got it bad," Grunkle Stan was elbowed by his twin as Ford said, "Don't worry, dear. We'll make sure to keep you safe from his clutches."

She smiled as the other two males nodded in accord. She'd always be able to trust her family to protect her.

The next night, Pacifica waited on the roof of the building where the performance was held. Stanford then appeared, and they both looked down the skylight. From there, they could see Fiddleford sitting in the audience, waiting for Gideon's act to come on.

As they peered over, they could feel the strange sense of a menacing aura. The headmistress squeezed her knee once the announcer came on the stage. They could hear the words clearly, "Now, ladies and gentlemen. Our favorite child star is back, Gideon Gleeful!"

The man walked off stage, and everyone waited for the boy to appear. It was only moments before he was suddenly standing before the audience on the stage. No puff of smoke to cover any trap doors, it was almost as if he appeared out of thin air! They cried and cheered as a welcome back. Fiddleford saw him grin wickedly.

"Hey y'all! It's been too long since I've seen ya'! I bet you're wondering, where's his amulet?" Gideon stripped himself of the baby blue blazer to reveal he didn't have the glass item with him. There were gasps and questions that arose from the crowd. Fiddleford was in disbelief, but quickly reported in his crystal communicator of what he was seeing.

"He doesn't have his amulet?" Pacifica asked incredulously. Stanford's gears in his head were turning as he thought of how he was able to appear on the stage so suddenly. The darker ambience he held, also the way Mabel described him yesterday…

"But no worries, ma' friends! Because everything I do now… is with ma' mind!" He declared mystically, before suddenly raising everyone out of their seats, even Fiddleford. But it was only slightly, he could still graze the leather of his chair. Wild cheering and whooping came from the audience once they came back down. Although, the engineer could feel himself growing steadily tired. He had no amulet, but how was his energy being drained?

"I'm getting more tired as I'm here," McGucket reported. Before the two could respond, they were abruptly pulled from the roof and through the glass. Shards flew and fell on the audience, much to their displeasure. But Pacifica and Stanford were suspended in the air, and he could see an odd dark light surrounding them.

"Well, lookie here! I caught myself the wonderful Northwest," Gideon flew her out above the audience and she wrestled to get out of the grip. "And the famous paranormal investigator!"

He brought back Pacifica and floated the Pines above everyone before returning him back to the stage. The audience's eyes widened as they identified the two and went crazy. They clapped and yelled and waved their hands around in amazement. Stanford grinded his teeth and viciously spoke at the boy while the audience couldn't hear them, "What game are you playing at, Gleeful?"

Said boy rubbed his thumb and index finger together and responded, "Good question. It's called, 'Spin the Idiots!'"

Before the scientist could ask, Pacifica and Ford were thrown around and around as Fiddleford and the others watched. When the boy was done, the audience went insane once more. The two floating in the air held down their nausea. Pacifica started to shout angrily, "I swear, Gleeful! When I get out of this, I will personally rip your stomach through your throat and–!"

Before she could finish, the two were forced behind the curtain, but still immobile. They heard the child continuing on with his show. It seemed to take forever until, "Well, that's all for tonight! Thanks for comin', y'all!"

Pacifica struggled to get her fingers on her crystal communicator. "McGucket, get out of there and report back to the academy. Write down our findings, Ford and I will deal with this."

The engineer gave a response of comprehension before running back to the school. The two waited for what seemed like hours, before they were suddenly thrusted back onto stage. The room was empty, but Gideon was grinning arrogantly as he let them out of his hold.

"Nice seein' you here. What can I do for ya'?"

"Your powers." Pacifica started, "What did you do with your amulet?"

"Oh yes, that is the big question." Gideon walked slowly around, as if he was taunting them to jump him. But the two stayed put, taking extreme caution in case he tried to make the first attack. "How about you figure it out for yourselves?"

Stanford put a hand to his chin thoughtfully, "Your amulet had dark power that used telekinesis… and your soul essence is much more sinister than before… Now, the burn wound is also healed."

"But the amulet is gone." Pacifica and Ford's eyes widened in recognition. Ford said breathlessly, "You… you absorbed its dark power?"

"Are you insane?" The headmistress berated, "That power is going to take over your soul!"

"Well, I'm not the one ta' reject it!" The boy gave them a deranged smile, "It's helped me so much! Healed me, given me power I can use ta' dominate over people. How can I throw away something so amazing?"

"You don't understand what you're getting yourself into, Gideon!" She continued to try and persuade him. But he just ignored her attempts and laughed maniacally. "I think you should worry more about yourself!"

"Pacifica!"

All of a sudden, she was thrown up into the air through the broken skylight. But she barely screamed in surprise. Pacifica somersaulted in the air and focused soul essence on her feet to give her a lighter landing. She was about to jump back in, ready to murder Gideon until she heard, "It's alright! I have this."

Biting her lip, she just chose to stay outside until he came out safely. It was her duty to protect Gravity Falls citizens, afterall.

"Tell me, Stanford. Do you happen to have any family other than your twin?" Said man glared at the boy as he continued to walk around. "Why?"

Gideon shrugged as he listed a few titles, "I don't know, maybe like, a cousin, or a sister."

The child looked up at the older man and smirked, "Or a grandniece and grandnephew?"

Stanford felt rage course through his body as he pointed an angry finger at him, "You stay away from them, you son of a—"

"Aha!" The boy interrupted him before he could finish, "So I was right. That boy and the darlin' Mabel is your family."

He grinned once more and threw his head back, "Oh, this just makes things even more fantastic!"

Suddenly, Gideon was in front of Stanford. But he was levitating right in his wrinkled face. "I'll destroy you and your brother, maybe the nephew too. Then I'll take her as my prize."

The scientist launched a fist at his chubby face. Leaving behind a portentous chuckle, he was gone before it reached him. Ford hastily looked around but he was nowhere in sight.

He slammed the doors behind him as he exited the building and stomped back to the academy. Pacifica was trailing after him, "What happened in there?"

"He's going to try to destroy my family and take Mabel." He briefly stopped to turn and look at her. "But trying is all he'll achieve."

They arrived at the academy in no time. Unlocking the door, she brought him in and they found Fiddleford waiting in the conference room. They started to discuss the new information they obtained.

She frowned as they sat at the table, "So, what we'll we do about his new powers?"

"Well, here's the thing," Stanford began, "Since the dark energy is now part of his soul, he'll have to continuously gain soul essence from people to survive. But at the same time, his power will steadily increase."

Fiddleford added, "But he won't have a limit to how much he collects. The darkness will keep becoming larger and larger until it entirely envelops what is left of his own soul."

"And he'll become a disastrous monster…" Pacifica finished. She tapped her finger against the table and pursed her lips. "This may become too much for us to handle if he keeps getting stronger."

"Shall we report this to his father?" Fiddleford suggested. Stanford hesitated but slowly nodded in agreement. They both looked to the young female and she said, "I suppose I'll tell him in my next meeting, which is in a few days. We'll see if he can do anything."

They had bid each other goodnight before going their separate paths. Ford walked onto the porch of his home and opened the door. Stan was sitting on the chair, watching television.

"Are the kids asleep?"

Stan nodded, and his twin gestured him to come outside with him. With a groan, he turned the TV off and put on a pair of slippers. They sat on the wooden planks of stairs below the starry night sky.

"What do you need, Poindexter?"

"Aside from training Dipper, you also need to prepare for a possible battle." He told his brother straight forwardly. Stan only raised a grey eyebrow in question, "With who?"

"Gideon. He's gotten more powerful now, and he'll keep getting stronger."

Stan scoffed, "The little freak? I'd love to stop him from dominating the world and all, but I kind of have random sores and pains in my old body. You know?"

Ford rolled his eyes, "Of course I know, we both do! But he's going to try to take Mabel and probably kill Dipper if he gets through us."

"Like that'll happen," Stan mocked, but Ford frowned at his laid back attitude to the situation. "I'm being serious Stanley."

"So am I," His twin brother replied, "There's no way I'll go down without a fight, especially if it concerns my family. But there's something about Dipper and Mabel that keeps me unworried."

"What, their souls?" Ford inquired. Stan just shrugged, "Maybe, but you have to believe in them, at least a little bit. You have too many wrinkles as it is."

They both let out gruff chuckles before heading back inside. The Mystery Shack was quiet once more.

Here we are again! I dont have much of a note to leave off of. But anyways, I hope you enjoyed this chapter!

Bye bye!
