Back where we left off
"D-Dipper?" asked Mabel in an incredibly confused tone.
"Mabel, you gotta listen to me," started Dipper 2. "The Dipper at your side is an impostor, I'm the real one!"
"And how can you prove it, know-nothing?" asked Dipper 1.
"Mabel can differentiate from us, right Mabel?" answered Dipper 2.
Mabel looked at the Dipper that came out of the bushes, and then the Dipper that was at her side. No matter how many times she saw either Dipper, Mabel was unable to find any difference between the two.
"I... I can't." said Mabel.
"What?" asked Dipper 2 with a worried look.
"I can't! I'm so confused now," answered Mabel. "There's a Dipper at my side, a Dipper that came out of the bushes, what's next? Another me standing by my side?"
Just as Mabel pointed at her other side, another Mabel was already on the spot. This Mabel was wearing a perfect copy of Mabel's clothes, including the emoticon on the sweater. Seeing Mabel 1 caused Mabel 2 to wave hello, while Mabel 1 had a "O_O" look on her face and sweater.
"Hello." greeted Mabel 2.
"WHAT?!" shrieked Mabel 1. "Okay, this is insane! And I'm the one who's saying it!"
"Calm down Mabel," said Dipper 2. "There must be a way we can discover who are the real ones and who are the impostors."
"There is a way." said Dipper 1, turning into his super form.
Before he could react Dipper 2 was attacked by Dipper 1, who went flying towards him and punched him hard enough to send him inside the Woods. Without noticing and before she could react as well Mabel 1 was hit by Mabel 2, who instantly transformed into her super form.
Luckily, Mabel 1 blocked Mabel's 2 punch and transformed as well, counterattacking with a blast that barely damaged Mabel 2. Teleporting behind Mabel 2, Mabel 1 executed a barrage of punches that Mabel 2 dodged before counterattacking with an upper kick and an up punch.
Back with the Dipper's
Dipper 1 and 2 were fighting above the lake nearby the forest, which was a pretty risky and stupid idea. Dipper 1 executed a barrage of punches which Dipper 2 effortlessly dodged before teleporting behind Dipper 1 and attacking him with a down punch.
Dipper 2 just barely avoided falling to the ocean and flew back to Dipper 1, giving him a rather hard punch to the face.
Back with the Mabel's
The Mabel's were fighting at the ground, close tot he lake the Dipper's were fighting in. Mabel 1 attacked her rip off by throwing a bunch of energy blasts, but she came out of them unharmed and with her hands forming punches. Flying high in the sky, Mabel 2 accumulated energy on her punches as she got closer to Mabel 1 and, once she was about to collide with her, shot her energy punches, causing a small crater to appear.
But just when she thought Mabel 1 was gone for good, she appeared behind her and formed a punch with her hand.
"You won't get rid of me that easily!" assured Mabel 1.
Turning around Mabel 2 could barely react as Mabel punched her, sending her flying past a tree and falling to the ground.
As the two continued to fight they eventually arrived close tot he lake the Dipper's were fighting in who, without their acknowledge, were doing the same punches and kicks as them. When Mabel 2 tried to grab Mabel 1, the latter holded her and fought to hold her back.
On her back Dipper 2 was doing the same thing with Dipper 1.
"This is absurd!" declared Dipper 2. "We're equal in strength, if we don't find a way to end this fight once and for all, this will go on forever!"
"Or until our energy runs out!" added Mabel.
As they continued to hold their rip offs back, the twins somebody calling "Hey!" from the distance. The twins turned around and saw Wendy atop of the hill on her super form, with some energy surrounding her palms.
"Wendy!" exclaimed Dipper in joy.
"What are you doing here?" asked Mabel with a tone of spite.
"I'm here to help you out," answered Wendy. "Trust me!"
With that said Wendy flew into the sky accumulating energy and once she was high enough, she threw two orange energy blast at the sky, which she momentarily stopped and joined them. As everybody watched Wendy started to expand the joined energy ball until it was big enough to become an artificial sun.
At the Northwests's Mansion
The shine of Wendy's artificial sun was shiny enough to be seen on all of Gravity Falls, though the first to notice was Pacifica. totally irritated by the artificial sunlight, Pacifica got off her bed and looked at the artificial sun.
"Alright, who turned on the sun?" questioned Pacifica.
Without warning Pacifica had a vision, one where Dipper and Mabel obtained their final forms and destroyed the crystal, ending as soon as it began. When she returned to reality, she narrowed her eyes and frowned as she changed to her normal outfit.
"Oh no! I'm not gonna let that happen!" exclaimed Pacifica.
At the Gleeful Residence
The sunlight also reached the Gleeful residence, specifically at Gideon's room. The boy woke up at the sunlight in his face, watching through the window to see the artificial sun.
"Is it morning already?" asked Gideon
Out of nowhere Gideon got another vision, this one was the same one Pacifica got though. After seeing it, he frowned and narrowed his eyes as he formed a punch with in palms.
"Darn it!" cursed Gideon.
Gideon punched the wall and went to change to his normal outfit.
"That girl and I should have been at the Mystery Shack hours ago!" said Gideon.
At the streets close to the Mystery Shack
Pacifica was running to the Mystery Shack while avoiding the intense sunlight from the artificial sun. Soon enough, Gideon catched up with her.
"What took you so long?" asked Pacifica.
"Just keep running!" replied Gideon.
The two continued to run while blocking their faces with their hands from the sunlight.
Back at the twins and their Doppelgangers... oh and Wendy
"An artificial sun!" exclaimed Dipper 1 and Mabel 1 in joy.
"An artificial sun?!" exclaimed Dipper 2 and Mabel 2 in horror.
"Guys!" exclaimed Wendy, getting Mabel 1 and Dipper 2 attention. "Transform into your pseudo-solar form while I maintain the artificial sun!"
Mabel 1 and Dipper 1 nodded and quickly trans formed into their pseudo-solar forms, which made Dipper 2 and Mabel 2 get a scared look as they tried to run away. However, the two were cornered by Mabel 1 and Dipper 2, who formed punches with their hands.
"Time to settle this!" stated the Pseudo-Solar twins as they got ready to attack.
The pine twins 2 gulped as the pine twins 1 attacked them with barrages of punches and kicks. And after a few repetitions, the pine twins 2 finished the pine twins 1 by launching to the water, by which they mysteriously bounced and returned to the lake nearby.
"Wow, it was over pretty quick." remarked Mabel.
Just then the artificial sun vanished as Wendy fell tot he ground close to the Doppelgangers. the twins went to her with worry.
"Wendy!" exclaimed Dipper, trying to wake up Wendy. "Wendy, are you okay?"
"maintaining that artificial sun took a lot of energy," said Wendy as she woke up. "It's a good thing you won while I maintained it."
"Thanks Wendy." said Dipper.
"It was no big," replied Wendy. "How are the impostors?"
The twins turned to see their doppelgängers turning into the twins look-a-likes, with two purple triangle coming out of their bodies and then turning into golden ones.
"Huh?" the trio were confused.
The triangles started to form each an arm and a leg and a half of a hat as they flew high into the air. Once high enough they started to combine, with a bright light and thunder forming around them as they did. Then an electric wave as the two triangles joined and formed a pyramid, with a single eye appearing in the middle of it. Guess who he was.
"Bill!" exclaimed the twins in unison.
"Who?" asked Wendy with a confused look.
"You got that right, It's me, Bill!"
"It wasn't enough to invade Stan's mind, but you had to possess innocent kids?" scolded Dipper.
"Wha-" asked Wendy.
"You told us you would leave us alone when we defeated you at your own game!" added Mabel.
"How-" said Wendy.
"Yes, but let's just say that I'm working with someone again and-" replied Bill before being interrupted.
"Hold it, hold it," interrupted Wendy, getting the twins and Bill's attention. "I'm lost, who's this guy? How do you know him? What the heck is he? The more you talk the more questions I get."
"I would gladly answer them, but my job here is done," said Bill. "I entertained myself with you long enough for Gideon and Pacifica to steal the crystal!"
"What?!" shouted the twins and Wendy in unison.
"Yep, and now that they have them, Gravity Falls will be at their total control, and afterwards they'll get rid of you!" continued Bill. "Now bye pines, enjoy what time you have left."
Bill vanished and Dipper and Mabel groaned in frustration... before he returned in an instant.
"Oh I nearly forgot, I have something to give you two." said Bill as he approached the twins. "Since I can't trust Gideon since the last deal we got, I'll give you a gift so you can kick his butt if he goes insane. Oh and if he tries to destroy the world, but mostly if he goes insane."
With his palm Bill formed two purple energy blasts, which he then threw at the twins. Oddly enough the blasts didn't explode, instead they surrounded the twins with a purple aura until the twins amulet lower half turned into a purple lizard with a yellow eye, and the aura disappeared as soon as it was done.
"What happened?" asked Dipper, feeling dizzy.
"I just unlocked the dark half of your powers," answered Bill. "Trust me, you'll need them if you wanna beat Gideon at his maximum power."
"Why do you give us this?" asked the twins in confusion.
"Didn't you heard what I just said? I can't trust Gideon!" replied Bill. "But you two are capable of giving him his medicine, and as much as I hate you for ruining my plan, Gideon's a far worse threat with the crystal in his and his girlfriends hands. And if you do beat him up, tell him the deal's over."
"See you later, alligators!" added Bill, briefly flashing the image of an alligator in his body.
Bill vanished for real and Wendy and the twins remembered what he said about Gideon and Pacifica.
Inside the Mystery Shack
After taking the look-a-likes back to their homes, the trio went as fast as they could to the. But alas, the crystal was already stolen, with Stan and Soos arriving to see the aftermath.
"What happened dudes?!" asked Soos, seeing the empty place where the crystal was.
"We met Bill and he told us Gideon and Pacifica stole it!" answered Dipper. "If we don't retrieve it before they use it to get their maximum powers-"
suddenly, an earthquake stroke and intense thunder was heard from outside. the shack team left to see that at Gopher's Street, a pillar of purple energy blasting towards the sky, surrounded by blue lighting.
"It's too late." said Dipper and Mabel in unison.
At Gopher Street
Where the pillar of light was happening, inside were Pacifica and Gideon, who laughed like maniacs as they gradually became more and more powerful until they turned into their last forms. Once that happened, an enormous wave of purple energy occurred, which was heard and seen from all of Gravity Falls.
On the scene as Gideon and Pacifica descended to the ground, Shandra Jimenez and her camera men arrived to make a shocking report of what was happening.
"Here Shandra Jimenez on Gravity Falls gossiper, with the biggest news since Gideon Gleeful's escape from prison," started Shandra. "As you can see from behind me, a giant pillar of something purple appeared and then vanished, and form what we're seeing the kids who were inside are finally coming down."
The cameramen gave a close up to Gideon and Pacifica, who reacted by blowing up the cameras. Everybody then reacted by fleeing for their lives.
"Guess that's all for today." said Shandra as she fled with the rest of the news team.
After that, Gideon and Pacifica got to the ground and their last forms were revealed, with their minions shaking in fear once they saw them.
Gideon had green eyes with turquoise sclera, his hair was even longer than before and he now had sharp teeth, along with a slit pupil. His outfit had turned into a black long-sleeved jacket with a red shirt underneath and spiked shoulder pads, ripped blue pants and spiked black shoes.
Pacifica's eyes were the same as her super form, but her dress was now slightly ripped, showing a few parts of her white undershirt. She also had ripped blue jeans and black spikes shoes like Gideon, along with a forked tongue and long claws.
"Yes... finally!" exclaimed Pacifica and Gideon in demonic voices.
Streets to Gopher Street
Grunkle Stan was driving the trio and Soos to Gopher street, though in a slower speed than before.
"Grunkle Stan, can't you drive this thing faster?" asked Mabel.
"What do you think I'm trying to do?!" replied Stan, hitting the accelerator pedal as hard as he could. "I think the accelerator doesn't work since the I last time we went to Gopher Street."
"Great, just great." sarcastically said Dipper in frustration, crossing his arms.
"Even if we do arrive eventually, what are we gonna do?" asked Mabel.
"Well, we did get the dark half of our powers for a reason," said Dipper while holding the amulet. "They must be useful for something."
"The what half of your powers?" asked Stan.
"Long story." replied Wendy.
"We arrived!" exclaimed Stan.
Stan parked close to the destroyed Gopher building and Gideon and Pacifica, along with their minions, came out and greeted the pine twins, who got out of Stan's car.
"Look who arrived just in time." said Gideon in a mocking tone. "I was hoping to see you soon enough."
"Gideon, Pacifica, stop this now," demanded Dipper. "Give up your powers, return everybody you possessed to normal and give us back the crystal!"
"Alright, I'll hand it back to you," replied Gideon with a smug smile. "After our minions have fun with you two."
Pacifica snapped her fingers and her friends and Candy and Grenda attacked. While the twins blocked what they did, once the possessed girl touched their palms some of their power was drained, with the twins noticing they were starting to get normal.
"So this is what the dark half of our powers do." said Mabel.
The twins eyed each other before getting ready to dash at the possessed girls.
"Prepare to be freed guys!" exclaimed Dipper.
The twins dashed to the girls and absorbed their possession, with them returning to normal as the twins palms were now surrounded by purple energy. However, their arms started to be surrounded by the energy, along with the rest of their bodies up until their entire bodies were covered with the stuff.
"Guys!" exclaimed Wendy in a worried tone.
The purple energy disappeared and half of the twins bodies were now different. they had a gray skin with red eyes and white hair. This sight shocked everyone, including Gideon and Pacifica.
"What does this mean?" asked Dipper, noticing what happened to him and his sister.
Without any warning, the twins collapsed on the ground and everybody went to check if they were okay.
Inside somewhere
Dipper and Mabel arrived at an indescribable place that looked like a combination of Mabel and Dipper's greatest fantasies. Behind them a dark liquid of some kind materialized in dark copies of them, Dark Dipper and Dark Mabel. The twins turned around and got shocked to see them.
"Who are you?" asked Dipper.
"We are you," answered Dark Dipper. "Well, your dark side at least."
"Where are we?" asked Mabel.
"Inside your indescribable and confusing combined minds." answered Mabel.
"Anyway, we have a deal for you." said Dipper.
"whatever it is, the answers no!" replied the twins in unison, crossing their arms and turning around.
The dark copies got an evil smile as they walked closer to the twins until they were back-by-back.
"Even if it is for the greater good?" whispered Dark Mabel. "For everybody's safety?"
The twins got a shocked look at what they said as the dark copies left them alone and walked a few steps backwards.
"What do you mean?" asked the twins in unison.
The dark copies formed a crystal ball, which showed a totally destroyed Gravity Falls.
"This is what will happen to Gravity Falls if you're unable to defeat Gideon and Pacifica." said Dark Dipper, with the twins watching in horror. "And quite clearly, at your current form you can't hurt them, not even tickle them."
The dark copies paused before continuing.
"But us, we know their weaknesses, and we have the power that will allow you to get rid of them forever." continued Dark Dipper.
Dark Mabel formed a dark orb in front of the twins.
"The deal is, we'll give you the power in exchange for your free will," said Dark Mabel, showing the orb to the twins. "We'll do all the work, all you'll do is watch."
"If you accept, grab the orb." added Dark Mabel.
The twins remained inert for a few moments before they started to slowly go for the orb, with the dark copies giving an evil smile as they approached it closer and closer. at the last-minute, the twins stopped and left the orb alone with angry looks on their eyes.
"No..." muttered Mabel.
"What?" asked the dark copies in unison.
"We won't accept." answered Mabel.
"Come on, don't you wanna save Gravity Falls?" reminded Dark Dipper.
"We will save Gravity Falls," assured Dipper. "But not with you."
"Come on you fools give in to the darkness!" ordered the dark copies in unison. "There's no other way to win!"
"You're a lie!" yelled the twins forming punches with their hands.
The twins punched the dark copies so hard they went flying to a wall, dropping the orb right in front of the twins. Mabel squashed the orb as her and Dipper's hair turned golden, while the dark copies watched in shock.
"Fighting darkness with darkness will only make everything worse," told Dipper to the dark copies. "The only way to defeat it is light!"
"You idiots, your stupid light can't compare to the powerful darkness Gideon and Pacifica have." informed the dark copies in unison.
"Then we might as well become so bright their darkness is extinguished once and for all!" exclaimed the twins.
The twins flew into the sky and their clothes, and eventually their entire bodies, started to glow a bright yellow color. They then screamed as they turned into their most powerful form, their solar forms.
Back in reality
The shack team was trying to wake up Mabel and Dipper while Gideon and Pacifica waited. They stopped once the twins opened their mouths and light came out of it, with them opening their eyes next, who were surrounded with yellow flames.
"What's going on with them?" asked Gideon.
"They finally achieved it." said the shack team amazed.
Mabel and Dipper flew into the sky and transformed into their solar forms, with everybody looked either in amazement or horror. On their solar forms, Dipper and Mabel had yellow eyes with white sclera, their hair were now longer, spikier and was constantly glowing a golden color. Their clothes were the same as the ones they always wore.
Teleporting behind Pacifica and Gideon, the twins gave each a strike to the super powered kids, who counterattacked, but failed in an epic way as the twins grabbed their punches and threw them to the trees.
"What's going on?" Candy as she and Grenda woke up.
Getting up and noticing the non-possesed girls, Pacifica and Gideon tried to re-posses them but they couldn't do it.
"Looking for this?" asked Mabel.
Gideon and Pacifica turned to see Mabel and Dipper holding orbs that contained Gideon and Pacifica's ability to possess someone, which they quickly shattered. Groaning in anger, Gideon and Pacifica went to flying to the solar twins and the big fight started.
To be Concluded...
