Gideon's EndGame!

A/N: Hello everyone! Alisi Thorndyke here coming at you with another yet another highly anticipated Gravity Falls story! Just a heads up, Jameer14 is writing a story named Digital Falls with a different plot and title from this fic so if suspicion suggests that we are copying each other's idea, I can already say that neither of us had any idea the other were writing a story like this until just recently. I informed him of my idea and he informed me of his so no confusion there. So if nothing else, onto the disclaimer, summary, and then the chapter! Enjoy!

Disclaimer: If I owned GF, I would be Alex Hirsch, but since I'm not him and is instead Alisi Thorndyke, then no I don't own it lol!

Summary: After receiving the newest video game for their birthday, the twins quickly become addicted to it. However when Dipper wishes to play the game for real, Bill Cipher grants his wish, transporting the two into the game and what was fun soon becomes the real deal when Gideon becomes the master of the game, ultimately raising the stakes! Will the twins survive or is it game over, permanently?

Chapter 1: Happy Birthday!

Birthdays, a magical time in every child, teen, and adult's life when….wait, rewind that. Let's just say child and teen as adults really don't want to be reminded year to year what age their climbing to next so let's start over. Birthdays, a magical time in every child and teen's life when gifts are abundant and making a wish happens by just blowing out a mere candle. Worries are an afterthought and everything one can dream of taking place during that special day fills the air, especially after seeing how decorated the house is for the party being thrown and the endless gifts that are stacked up on a table on one side of the room ready to be opened by the birthday girl or boy. However, if the birthday taking place is for a set twins, then that could make things more interesting gift wise as the twins interests would vary, but that would only be if they aren't these set of twins…..

"Happy Birthday Dipper and Mabel!" Wendy, Soos, and Stan wish to the Pines twins as a cake is placed in front of them on the kitchen table, Mabel's eyes growing wide at the sight of the thirteen candles lighting up the cake.

"Make a wish dorks." Wendy says to the two with a laugh. "And make it a good one."

"Oh I'm going to wish for a talking horse." Mabel expresses. "No wait, I'm going to wish for the dreamy guy from my vampire novels. I'd love to have him at the party! No, no, not that! I know! I'm going to wish for-"

"Mabel, you don't voice your wish out loud." Dipper cuts in with a laugh. "You think it to yourself and then blow out the candles. Your wish will come true after blowing out the candles."

"Ok, so what do you wish for?" Mabel asks turning to twin.

"Now that, my dear twin, is a surprise." Dipper says with a sly grin. "If it comes true, you'll know what it is."

"Is it to spend the day with Wendy?" Mabel teases as she playfully elbows Dipper. "Come on, tell me."

"Ssshh, Mabel!" Dipper replies, a look of embarrassment crossing his features. "I told you I can't tell you, not yet anyway."

"Come on kids, blow out the candles." Stan urges. "Do you want the shack to burn down or what?"

"Ok, we're going to blow them out now." Mabel replies to Stan, she and Dipper now turning to their cake, their eyes locking on the thirteen colorfully lit wax sticks. Closing their eyes, Mabel and Dipper begin thinking about what they truly want for their birthday.

"I wish to see Mermando again and tell him how I truly feel about him." Mabel wishes to herself. "But if not him, the guy from my vampire novels!"

"I want Wendy to kiss me!" Dipper wishes excitedly to himself. "Oh and I want the new Dragon's and Evil video game. If I get either or, I'll be the happiest guy on the planet, but I would prefer wish number one though."

Opening their eyes, the twins now blow out their candles with Mabel smiling wide.

"Today, I am officially a woman." Mabel voices, which causes her brother and uncle to shudder.

"Mabel, whatever you do, never say that again." Dipper speaks, disgust evident in his voice. "At least not while I'm around. That's not something your brother should ever hear you say. Today, you're officially a teenager, you're not technically a woman until you're 18 years old."

"When that time comes, I don't even want to know, but I'd kill any guy who breaks your heart!" Stan informs her. "He won't know what pain is until he's met the pain I'd give him!"

"Awe, thanks grunkle Stan." Mabel replies as she bats her eye lashes.

"Ok, now is the time to open presents dudes!" Soos happily announces, now wheeling in the gifts on a cart that were stacked up on a table in the den. From the looks of the gifts stacked on the cart, the twins got quite a bit of birthday surprises, the first two in front on the cart being from their parents whom couldn't attend the twins' party due to having business to attend to in California. So what a better way to say happy birthday to your kids than to send them a slew of presents?

"Ok, the first gift is for Mabel." Soos announces, grabbing a pink gift wrapped present off of the cart and handing it to Mabel. Mabel, unable to contain her excitement and seeing who the gift is from, tears the wrapping off of the present to reveal that her first gift is another volume of her vampire book series.

"That must be from mom." Dipper points out as he grabs the wrapping to see whose name is on the to from label. He notices that the gift is indeed from their mother. "Yep, I was right."

"Thank you mom!" Mable sings, hugging the gift close to her.

"The next gift is for Dipper." Soos sings, now handing the younger pines a small, but flat gift. Looking on the label, Dipper notices that the gift is from his parents, his father's name being the one to stand out more with a subtitle stating: Don't tell your mother.

Tearing the paper away on the gift, Dipper's eyes and smile widens as he gets a good look at what the present is.

"Oh my gosh! Oh my gosh! I got it! I finally got what I've been wanting for my birthday for a long time!" Dipper yells in excitement. "I got the new Dragon's and Evil video game! I finally got it Mabel!"

"I see Dip." Mabel smiles with a nod. "I'm happy for you."

"The next gift is for Mabel." Soos says handing Mabel her next gift that appears shapely, but bulky.

"I wonder what this is." Mabel asks in confusion, now looking on the label to see who the gift is from. It says it's from her mother. Opening the gift, Mabel's eyes widen with her brace filled smile widening that much more at the sight of the pink and red sweater her mother has shipped to her.

"Thank you mom!" Mabel shouts as she hugs the gift close to her. "I thought I lost this back at home, but thankfully mom found it for me! Either that or she knitted me another one."

"Mabel, you have like a million sweaters upstairs right now." Dipper comments, eyeing the piece of clothing. "I don't think you will have room for another one considering how much space your other sweaters are already taking up in the closet."

"Don't worry Dip, I'll make room for this one." Mabel replies. "I've been looking for this sweater forever and I can't believe mom found it."

"It was most likely buried up under all of your books and yarn in your room." Dipper replies. "I wasn't able to find the cat for a few days until I went into your room and found him there."

"The cat was in my room?" Mabel questions in confusion. "I thought he ran away like the first cat did."

"Ok, how about you guys enjoy your cake now and open the rest of your gifts in a little bit." Wendy suggests, seeing that the amount of gifts that they have will take them the rest of the night to open, but no need to let the cake get stale in the process.

"Do we get to have ice cream with the cake Wendy?" Mabel squeals with excitement.

"Yep and it's your favorite, Neapolitan." Wendy replies, revealing the large tub of ice cream to them as she sets it on the table next to the cake.

Dipper and Mabel turn to each other with wide smiles and high five the other.

"Best 13th birthday ever!" Dipper and Mabel say in unison.

"I really can't wait until you kiddos see what I got you for your first year of being teenagers." Stan adds in. "You're just gonna love it, especially you Dipper."

The smiles the twins' held now falter as they turn to each other with questionable looks.

"Should I be worried?" Dipper mumbles to Mabel, who shrugs in response.

Gleeful Residence (Gideon's Room)

Sitting at the desk in his barely lit room is Gideon Gleeful, him currently reading through '2'. On the wall above his desk is a calendar that is set to the month of June and the date '18' is circled in red ink with a small picture of Mabel taped under the date. Having been released from jail not too long ago, Gideon is still bent on getting his perfect revenge on Stan and Dipper for getting in the way of he and Mabel's non-existent relationship.

Currently staring at the page of the journal that explains how to create a blood reign, Gideon crinkles his nose at what it will take to do that job.

"I just bought this suit and there is no way I am messing it up." Gideon scoffs as he turns the page, now spotting a spell to summon the seven signs to signify the end of the world. "Ok this looks interesting, but that would mean I'd go down in the process without having kissed my lovely queen Mabel. No thank you."

Turning to the next page, he now spots the spell to summon Bill Cipher. After the last deal the boy made with the demon, their plans to get the combination to the safe that contained the deed to the shack fell through, leaving Gideon to resort to dynamite to get what he wanted. After the deal was broken, the albino made it a note to never work together with the demon again due to how badly things turned out before. However, since he is not coming up with any good plans to get back at his nemesis(s) on his own, his last resort to get his revenge maybe whom he is doing his best to avoid.

"As much as I don't want to do this, what could it hurt?" Gideon speaks to himself. "We can't fail a second time."

Sighing, Gideon sets his book on the desk on its spine, reading over the spell to once again summon Bill Cipher, but before the boy can grab his picture of Stan from the desk drawer that he once used to summon the demon, the surroundings in Gideon's room becomes still with the yellow dorito shaped demon now appearing.

"And here I thought you meant what you said about never working with me again." Bill nonchalantly speaks, frightening the white albino haired boy, him whipping around and seeing Bill floating above his bed with his cane. "But I guess even you are entitled to a change of heart, what little there is anyway."

"Bill?! How…how..did you get here?" Gideon stammers, still frightened at the sight of the dream demon. "I didn't summon you!"

"Let me let you in on a little something kid." Bill begins as he approaches Gideon. "Once you open the portal to summon me, I can freely pass between the worlds as I wish. So until that portal is closed, the dreamscape isn't the only place I can frequent when I want to."

"But how did you know I was going to summon you?" Gideon asks, his heart rate and pulse beginning to relax from initially being frightened by the demon's presence.

"Master of the mind remember?" Bill reminds me as he places his hands behind his head while closing his eye. "I know everything, including what you're thinking right now."

"Ok then, what am I thinking about?" Gideon questions, crossing his arms across his chest in disbelief. "Other than the usual?"

Without a word spoken, Bill snaps his fingers with a version of Mabel appearing to the right of the albino. Her eyes widen with happiness as she quickly becomes love struck upon seeing Gideon.

"Oh Gideon, I love you and will be your queen!" Mabel happily shouts as she clings onto Gideon's arm. "The answer is yes! Now and forever!"

Turning the boy's face to hers, Mabel lovingly lowers her eyelids, ignoring the deep blush that is covering his cheeks.

"Let's start planning our wedding, but first, kiss me." Mabel requests, now pursing her lips to prepare for Gideon to kiss her. Smiling wide at seeing his one true dream standing to the right of him, Gideon closes his eyes and puckers his lips so to kiss his dream girl.

To avoid gagging at the sight of Gideon's inner fantasy, Bill snaps his fingers once more, Mabel instantly disappearing from Gideon's arm. Leaning forward so to kiss Mabel, Gideon reaches his arms out to grab Mabel, but instead, ends up grabbing onto himself. Opening his eyes and seeing his dream girl gone, the boy frowns and whips his attention back to the demon.

"Hey, bring her back!" Gideon demands. "She truly loved me! If the real Mabel continues refusing me, at least I'll have her."

"Not a chance short stack." Bill replies, his vision still not being caught with the albino's. "I'm a vengeful dream demon, not a genie that can grant you three wishes! You failed at coming up with a plan to get back at Stanford and Dipper on your own, which would explain why I'm here. Now speak your peace or forever rest in it."

"Well, I happen to know that today is Mabel and Dipper's birthday and I really want to give them something really special, especially Dipper." Gideon says to the demon, him spitting out Dipper's name as if it were poison. "I'm having a hard time coming up with something memorable, but I do have a few things in mind that just may do the trick. I really want to make sure this is a birthday neither of them will ever forget!"

"Really? Well then spit it out short stack." Bill replies, now making eye contact with the boy, his eye shifted into the expression of interest. "This I want to hear."

"Good and listen well because I'm only going to say this once!" Gideon sternly replies to the demon. "And don't twist my words when I tell you as I want this deal seen through to the very end word by word, but be warned that if you screw this up, I will take matters into my own hands of closing your precious portal forever!"

"I'm all ears." Bill voices, seeing the creepy and devious smirk quickly appear on the chubby boy's face. Something in the back of Bill's mind is telling him that this particular deal with Gideon will be anything but simple….

Mystery Shack Den (8pm)

Having opened the rest of their gifts, including Stan's that were surprisingly good considering the type of person he is known to be, Dipper is sitting in the den playing his new Dragon's and Evil video game. From the intense look on the boy's face, it appears that he has been playing the game for quite a while.

"Almost there, almost there." Dipper mumbles to himself as beads of sweat begins forming on the boy's forehead while he feverishly thumbs the game controller. "Can't stop now, have to keep moving."

Moving the joystick in a clock wise position and hitting the A button, an explosion is heard from the game with Dipper jumping to his feet while pumping his fists in the air.

"Yes! Level two!" Dipper cheers. "I finally made it! Take that destructor! Dipper Pines is the master of this game! You have to answer to this guy now!"

Mabel now descends from the stairs dressed in her bed clothes and is brushing her wet hair having washed it in the shower. Entering the den, Mabel notices that her brother is dancing around in the room with the game pad still clutched in his hands.

"That must be some game Dip." Mabel speaks, now catching her brother's attention. "You've been playing it for five hours now."

"You have no idea how great this game is Mabel." Dipper replies, his tone still victorious from his win. "I just made it to level 2! I have to thank dad for getting this game for me!"

"Alright, well I'm heading to bed now." Mabel informs him with a yawn. "I'll see you up there and when you come in, make sure Waddles isn't by the door as he still hasn't recovered from you stepping on him last night when going to bed."

"Ok, I'll be up in a minute." Dipper replies, now waving her off as he takes a seat back on the floor in front of the television. Having reached level 2, Dipper is once again feverishly thumbing the game pad in order to make it through the stage. With another yawn, Mabel now heads upstairs to their bedroom, unaware of the triangular shaped shadow that is sliding along the walls close to the den…..
