Disclaimers: I do not own Gravity Falls

Author's Notes: Please note we had to make a small change in the story. The Great Demon War that happened 30 years ago has been moved to only 14 years ago. This change was made for the sake of plot. Sorry.

Thanks for reading and please review.


(Back with Bill…)

There was very little that got him excited when it came to this mudball called Earth, but this…this showed potential.

At the moment a pep rally was being held in the Gravity Falls High school gym, and most of the students in attendance were cheering in support of their sports teams. However, Bill being the twisted demon he is thought these teams were some kind of Gladiators pumping up for a death match. "Now this is more like it!" He exclaimed.

"I know aren't pep rallies the best?" Mabel exclaimed.

"Totally." Bill agreed. Though he wasn't sure how Shooting Star could tell, she had her eyes glued to her phone. Apparently, someone by the name BillCipherFan15 had created a discord in Bill's honor and loads of people continued to join each day to talk about their love for Bill. Bill referred to them as his loyal subjects and Shooting Star monitored the site for him daily. "So, what's the word?"

"Oh, everyone is going crazy about the game tonight." Mabel reported. "They want to know if you'll be there."

"Of course." Bill exclaimed. "If my subjects request my presents then I am so there." He laughed evilly.

"You're really into this huh?" Mabel asked.

"Yeah we use to have this in the Nightmare Realm." Bill explained. "Until my father banned them, saying they were too barbaric."

"Really?" Mabel asked. "Why?"

"Well My Grand Father Seth created the games and since he was labeled evil, everything he stood for was erased from Demon History." Bill explained.

"He's your grandfather?" Mabel asked.

Bill nodded. "No one calls him that since he's an utter embarrassment to the family, but his full name is Seth Cipher and the next king was my dad so yeah even an idiot can put two and two together."

"Can you guys keep it down?" Dipper hissed from beside them. He currently had a laptop on his lap. Instead of paying attention to the festivities he was trying to get some much-needed work done. Much like Ford, Dipper was working on getting his degrees early in life, and while he attended high school, he also attended several online college classes. However, he had been falling behind lately thanks to Bill's shenanigans.

"Oh, come on Dipper live a little." Mabel exclaimed. "This is our first pep rally of our High School career." She insisted.

"High School isn't a career Mabel, it's a phase." Dipper lectured. "And when are you not excited?" He added.

"Wow someone woke up on the wrong side of the Bantha Beast today." Bill joked.

"What's a-" Mabel began to ask, but Dipper cut her off.

"It's a giant rabbit like meat-eating monster that roams the dark forests of the Nightmare Realm." Dipper huffed. "Look I'm sorry but I have an exam tomorrow that could pretty much decide my grade for the rest of the semester. My perfect GPA is on the line here."

"You got it bro. I'll keep an eye on Bill for the day." Mabel assured him and turned to explain to Bill. "Sorry Dipper gets like this when it comes to his studies, so it's just me and you today."

"Cool I get the fun twin." He winced the moment the words left his mouth. "No offense Pine Tree." He added quickly.

"None taken." Dipper assured him, not looking up from his work. "I am labeled the responsible twin, and I am ok with that."

Suddenly a Teacher Mr. Skeeves addressed the students at the center of the gym. "And now, Pacifica Northwest who became head cheerleader on her own, and not because her dad made a generous donation to the school!"

The cheerleaders walked up to the podium.

"Go, Gravity Falls High! Let's try not to get beat! Go, GFH! Let's try not to get beat! Go! Go! Go! Go! Yeah!"

Pacifica then addressed the crowd, "Make some noise if you love the Awesome Opossums!"

Mabel yelled, "Oh, I love opossums! They carry their babies on their backs!"

"What do Opossums have to do with gladiator games?" Bill asked openly.

"It's our mascot." Mabel explained, missing the Gladiator comment.

Dipper however did not. "You know she's talking about our basketball team, right? We're going up against the Warriors," he explained, then shuddered in a mixture of fear and doubt.

"Warriors?" Bill asked.

"Our rivals from Windber," Mable added. "Every year we get absolutely crushed by them."

"It's gonna be a bloodbath," Skullnick added.

"That's Awesome!" Bill exclaimed. "I want to get in on this."

"Well, you could join the Spirit Committee. Those kids are relentless when it comes to supporting the team," Dipper explained.

A guy near the podium holding small flags with opossum designs did the splits while yelling "Opossums!"

"Relentless," Dipper repeated.

"What a great idea! We better go see where we can sign up!" Mabel shouted as she took off taking Bill along for the ride.

"As fun as that sounds, you can go without me," Dipper said mostly to himself. He sighed as he returned to his work. "Finally." He smiled as he noticed the pep rally ending. The rest of the day's classes were canceled to prepare for tonight's game. Which meant he was now free to study to his heart's content.

Or was he?

Could he really trust Mabel to keep Bill in line? After all he had promised Ford. Dipper sighed and decided to take a quick break to see how Mabel was getting along with the job before things got out of hand.


(Following Mabel and Bill…)

"Come on Bill we have to hurry before sign ups close." Mabel insisted as they ran through the school hallway. Bill stops in front of a trophy case that houses pictures of former Awesome Opossums team members.

"Well no wonder all these people died, they're toothpicks!" He realized. "I can't be caught dead supporting a losing team." He realized. "I have to do something, or this will ruin my reputation."

Meanwhile, Dipper was sneaking down the hall towards Bill, he was trying not to be seen. After all he didn't want Mabel to think he had no faith in her. He continues sneaking through the hall, shimmying against the walls and rolling on the floor until he's next to the trophy case.

"Oh, hi Pine Tree." Bill said casually.

Dipper surprised, falls over with an "Oof!"

"Spying on us so we stay out of trouble?" Bill asked the obvious.

"Please don't tell Mabel." He begged as he got up.

"You could just join us." Bill suggested.

"No, I already made a big deal about studying." Dipper explained. "If I join you now Mabel will think I don't trust her to be responsible without me."

"But you clearly don't." Bill pointed out. "Otherwise you wouldn't be spying on us."

"I know, and I trust her, I do…but sometimes…" Dipper trailed off.

"She gets distracted." Bill concluded.

"Yeah." Dipper agreed as he notices the trophies Bill is looking at. "You really seem into this sport stuff." He said.

"Yeah I think so." Bill admitted. "Got any pointers I can share with the Spirit Committee?"

"Well, if I knew anything about Basketball, I'd use the element of surprise." Dipper answered.

"Of course!" Bill exclaimed.

"Spritz 'em! Bring out the kitty cat offense!" Dipper said, obviously joking. "Maybe even throw a couple spirit bombs."

"Bombs! Yeah, I've gotta go tell that to the Spirit Committee. Bye!" Bill exclaimed.

"Wait, Bill I was…joking." He groaned openly. Surely, he knew he was kidding…right? Dipper moves to chase after him when his watch alarm begins to go off, reminding him to study.

Oh well, Mabel wouldn't let Bill do anything too crazy, besides the demon Prince was right, he needed to have more faith in his sister. So, without much thought he headed towards the library to continue his studies.

Meanwhile, Bill has caught up with Mabel, the Spirit Committee was practicing on the football field outside, leaving the gymnasium open for the basketball team to hold one final practice of their own.

At the moment the cheerleaders where practicing the Pyramid move of their routine.

Pacifica who was holding a megaphone was reassuring one of the girls. "Don't worry, Sabrina. The Spirit Boys are gonna catch you. Grow some pompoms!"

Sabrina jumps from the top of the Pyramid and flips through the air.

"Aren't they great?" Mabel asked.

"Not really." Bill retorted and then shouted. "You call that a jump?"

"Huh?" Asked the boys who were supposed to catch Sabrina, of course this distraction causes them to miss her coming and she face plants into the ground.

"What the-?" Pacifica turns to see Mabel and her eyes narrow. "Of course." She hissed as she stomped over to them. "Mabel, I thought I banned you from Cheerleading practices." She snapped.

"But this is the Spirit Committee meeting." Mabel told her. "Not cheerleading practice."

"Well that's what we're using it for." Pacifica informed her. "Now leave."

"Hey, you can't talk to her like that!" Bill said.

Pacifica, who looks like she could care less just brushes him off. "Uh, we're kind of in the middle of something here."

"And we just want to help." Mabel said.

Pacifica rolled her eyes. "Fine you and your weirdo friend can paint banners or something with the other losers over there." She pointed to a group of two girls.

Mabel smiled when she noticed it was her two friends Candy and Grenada. "Come on Bill."

Bill growled but followed Mabel none the less.

"Hey girl, been a while." Grenada said.

"Yeah sorry." Mabel said as she picked up a paint brush to start helping on the banner. "Guys this is Bill, he's the one I told you about."

"So, you're like from another dimension?" Candy asked. She and Grenada were the only people who knew where Bill was really from besides the School staff. Sure, everyone knew Bill could do magic, but the fact that he was a demon prince was being kept on the down low. Mostly because the word demon tended to cause mass panic when it came to the history of mankind.

"Yeah." Bill said not really paying attention.

"What's it like?" Candy asked.

"It's fine." Bill brushed her off and turned to Mabel in a huff. "I can't believe you let her treat you like that."

"Who Pacifica?" Mabel asked.

"Yeah where does she get the idea that she can talk to you like she's better?"

"Shhh." Grenada warned.

"Why?" Bill asked.

"Look Bill, you know how you're the prince?" Mabel tried to explain.

Yeah." Bill answered.

"Well Pacifica is the closest thing to royalty in this town." Candy cut in. "Her family founded Gravity Falls."

"Which means they own all the stocks and most of the property." Mabel added.

"In short she's rich and cool." Grenada said. "And we're not."

"Oh, come on your plenty cool." Bill said to Mabel.

"Pacifica likes order." Mabel explained. "We just don't fit in with her standards."

"It doesn't matter." Candy assured her. "We can have fun at the game all the same."

"You're coming right?" Grenada asked them hopefully.

"Oh, we'll be there!" Bill said darkly. "And we'll blow Pacifica away with spirit bombs." He vowed.

"Now you're talking." Mabel exclaimed. "Now pick up a brush and get to work." She ordered.

"Actually, you ladies continue without me." Bill said mischievously. "I'm going to get some…supplies."

"Okay I think you can find some stuff in the art room down the hall." Mabel suggested.

"Got it." Bill said sweetly, and march off, the prince was on a mission. He'd bring an offense so spectacular and intense that it would show up Pacifica and her snotty family once and for all.


(Later That Evening…)

It had taken Bill the rest of the school day to pull it off, but after the Basketball team hit the showers, he set to work on preparing the battle field, and he had to admit he was pretty proud of his work, and finished up shortly before students started pouring in.

Mabel walked in with her two friends from before and waved him over to the bleachers.

Bill joined them.

"So, how'd it go?" Mabel asked. "You were gone a while." She said.

"It's all taken care of." Bill assured her.

"Okay." Mabel said with a shrug.

Dipper arrives shortly after and sits down beside Bill.

"Pine Tree, I thought you were studying?" Bill said.

"Just finished." Dipper reported. "And just in time for the game."

"Nice." Bill remarked.

"So, how'd Spirit Committee go?" Dipper asked.

"Oh, we made Banners." Mabel said casually.

Dipper looked around to see Banners painted "GO TEAM." All around the gym. "So, nothing eventful happened then?" He asked confused. "Like no magic slip ups, no nothing?"

"Uh Bill?" Mabel asked.

"Nope, no slip ups." Bill assured her.

Dipper's eyes widen in alarm. "Mabel why are you asking Bill? You were with him the whole time. Right?"

"Well yeah, but he went to get supplies." Mabel said.

"Oh." Dipper began to relax, that didn't sound so bad.

"Yep and now that the battlefield is prepped, we are guaranteed to win." Bill assured them.

"Battlefield?" Candy asked.

Dipper felt his blood run cold. "Bill, what did you do?"

"I just increased our odds of winning." Bill said. "I noticed the field lacked any traps or weapons, so I added a few."

"What?!" Mabel and Dipper said in disbelief.

The entire basketball court was covered in lasers, spike bombs, and pit traps. How Bill managed to set all of this up without anyone noticing was beyond their comprehension.

"Bill! The Warriors weren't actually going to kill our team!" Dipper yelled.

"Yeah, they were just gonna beat them in basketball! Which is a game!" Mabel added.

Bill's smile disappeared in realization. "Ohhhh…" He laughed. "I thought these were fight to the death games. Those were the only kind of sports we use to have in the Nightmare Realm."

Dipper face palmed. He should have known better then to let Mabel handle this. "Its fine, all we have to do is warn everyone before the game starts."

The referee blew his whistle, signaling the opening tip off.

"Too late." Grenada said.

The basketball was tossed into the air and a GFH player caught it, but a nearby land mine blew up as Windber got into a defensive formation. The resulting explosion set off other land mines on both sides of the court, causing most people to scatter. One of the Warriors got pulled into a blue vortex thing, all while Bill looks on in worry and guilt.

"Oh, no! Everything's going according to the plan!" He said. "Why am I so good at making explosives?"

Near the Opossums basket, several large creatures, including three-eyed cat monsters rise from the floorboards.

"Let me guess: the 'kitty cat offense'?" Dipper asked.

Bill nodded. "Anything goes in Demon Gladiator Games." He explained.

"Well this isn't the Nightmare Realm!" Dipper shouted. "We have to do something!"

"We'll try getting everyone out safely." Mabel said. "Come on girls."

Candy and Grenada followed her lead as Bill and Dipper set off to disarm the rest of the traps.

Suddenly squirrel monsters burst from the ground and lunged for Dipper.

Dipper stopped one by stepping on its tail and upper cutting it in the chin.

"Mending Heart Hurricane!" Bill shouted with a wave of his cane.

The squirrel monsters then turned back into normal squirrels.

"Wow you are getting better at this." Dipper noted.

Meanwhile, one remaining squirrel monster grabbed Pacifica with its mouth.

"Lightning Wipe slash!" Bill shouted.

A beam of light shout out of his cane and hit the beast so hard it dropped Pacifica with a loud screech and charged.

"Nuclear Mending Heart Hurricane!" Bill yelled.

A large blast of magic surrounded the court, and any remaining monsters reverted to their previous, non-deadly forms.

Dipper noticed Pacifica and reach down to help her up.

She turned up her nose and huffed as she got to her feet. "My daddy will hear of this!" She swear. "Your weird family has done it this time!" She began to march out of what was left of the gym. "You will be hearing from my Lawyers Pines!"

"Oh boy." Mabel said as she and the girls joined them.

"I've… really messed up," Bill realized.

"You mean, we've really messed up." Dipper said. "I should've been watching out for you, and Mabel I shouldn't have dumped my responsibilities on to you" He added.

"And I should have paid better attention." Mabel admitted.

"Let's get outta here!" A Warrior yelled, and all of the Windber players ran out of the gym.

"Hey! They just forfeited! We win!" A GFH player yelled, and the crowd cheered.

Bill cheered as well. "Woo-hoo! Huh... Why do I have this weird feeling I'm forgetting something?"

"Bill!" Dipper warned.

"It's on the tip of my tongue." Bill said thinking really hard.

Just then a large snake slithered up and grabbed Dipper, pulling him away.

"Yeah, that's it," Bill shouted. "After it!" He and the girls charge as the beast slithered off.
