The Mystery Shack, Living Room 4:30 p.m.

30 minutes after the twins disastrous fight, they had returned to their normal forms and were now at the Living Room sitting on the couch, while an angry Stan was looking at them.

"Do you understand how much money did that room cost?" asked Stan. "It cost me 100 dollars!"

"Grunkle Stan-" said Dipper and Mabel in unison.

"Silence!" interrupted Stan.

The twins closed their mouths when they heard that. Grunkle Stan was know for being grumpy and angry frequently, but this Stan was so angry it was almost scary.

"You can't just start a fight in those, weird versions of yourselfs and hope everything will be alright, we have continuity!" yelled Stan. "See that huge S on the ground, it's been right there for episodes!"

"Grunkle Stan, we didn't meant to destroy the room like that." said Dipper. "We just got angry, transformed into our super forms and... it just happened."

"You two need to be more careful in those weird versions of yourselfs." scolded Stan.

"We're sorry." apologized Dipper and Mabel.

"And for your punishment, I will remove 15 dollars from our overall pay in the mystery shack." said Stan.

After hearing that, the twins just nodded in agreement. Stan sighed and changed fomr his angry tone to a more calm, but still somewhat angry one.

"Okay, Now, I need to talk with you about those 'super forms' you transformed into when you destroyed your room." said Stan, sitting with the twins on the couch. "So what happened? No, how did you transformed? No, HOW DID THIS EVEN HAPPPENED?!"

"Well you see, I was minding my own business last week of last week, thinking about cute boys and everything." started Mabel. "And then, while I saw Dipper fast asleep, I saw he was holding his book in his hand-"

"Skip the unnecesary parts, I just wanna hear how you got those super forms." interrupted Stan.

"I was getting there." said Mabel ass he resumed. "Then I carefully grabbed the book and opened it, being curious about what Dipper never allowed to let em see. And then I saw a page about a transformation crystal in the forest, which is the one we brought to the shack."

One Summary of What Happened In the last 3 Chapters Later

"And then we got here where you scolded us for destroying our room hwile we were in our super forms and we started explaining how we got said super forms." said Dipper, finishing the explanation.

After hearing the whole explanation, Stan had his eyes closed as he got off the couch and walked forward with his arms in his back. A long silence happened as Stan remained quiet for a few more minutes before finally talking.

"I don't believe either of you." said Stan.

"Predictable." mentally said Dipper unamused.

Stan then walked to the crystal and took a deep look at it.

"I cannot believe you for real, if you say this crystal gave you those powers" said Stan. "This crystal, that's protected from danger on the outside thanks to the gumball machine-like glass, and that doesn't look too different from any other crystal in the forest, gave you those super forms?"

"Uh huh." answered the twins in unison.

"... Do you really think I'm that stupid?" laughed Stan, getting to his serious tone in an instant. "There must be another reason you got those transformations and I want the truth."

"Please Grunkle Stan, believe us." requested Mabel as she put puppy dog eyes. "Please?"

"You do know I'm immune to that stare right?" asked Stan.

"Darn it." said Mabel, returning to her normal eyes.

"Stan, we really got our super forms from the crystal." stated Dipper. "And outside of the outbursts, the only way we can transform is using the energy from the crystal."

"An outburst? You mean those sudden and violent display of emotion?" asked Stan.

"Yeah, why?" Dipper asked nervously.

Dipper started to get an idea about what Stan was gonna do next, and unfortunately, he also knew what he was gonna use to cause an outburst. Stan took out from his back a magazine extremely familiar to Mabel. It was her 3rd edition of 'Vampire Boy Band', a magazine about a boy band that were secretly vampires.

"Do you recognize this, Mabel?" asked Stan, shaking the magazine.

"H-How did you got that?!" asked Mabel, blushing.

"Mabel, I'm me, what you should wonder is how I didn't got this." answered Stan.

"Oh no Stan, please don't go that far." mentally warned Dipper.

"I had to wait 55 minutes in a long line to buy that edition, do you know how precious that thing is to me?" asked Mabel while her eye twitched and her eyes color flashed from the black dots to her cerise color.

"Wouldn't it be so bad if something happened to it?" asked Stan.

"Stan, I have been waiting for a long time to have that magazine, and even if I have readed it yesterday, I still want to enjoy it." said Mabel as her eye color finally turned cerise and her hairstyle turned spiky in an instant. "And if you dare to even land a scratch on it-"

"Oh, you mean like this?" asked Stan as he grabbed both end of the magazine.

Stan ripped the magazine in half, right in front of the twins. While Dipper had his mouth open out of sheer shock, Mabel's anger had rised to such a high level she transformed into her super form in an instant and went flying to Stan.

Stan, knowing what was going to happen, moved out of the way and Mabel crashed into a nearby bookshelf. After finding Stan again, she dashed towards him, but instead of moving out of the way, Stan held his hand forward and Mabel hit her head with it.

"Ouch." said Mabel as she returned to her normal form. "What was your reason to rip my newest edition in half?"

"My reason was to see if what Dipper said about the outburst was true." answered Stan, Mabel giving Dipper a glare. "And besides you shouldn't worry about that edition too much."

Mabel was confused about what Stan was saying. Stan walked to a nearby common wall and, after hitting it a few times, opened to reveal a collection with the 5 editions of 'Vampire Boy Band'. Seeing the collection, Mabel squeeled in excitement as she grabbed one copy of the 3rd edition.

"Where did you got this?" asked Mabel.

"I know someone from another dimension." answered Stan, earning a confused look from the Twins. "Just kidding, I know someone."

"So umm..." said Dipper.

"Ah yes you, do you know what else have you and your sister figured out?" asked Stan.

"No, we only discovered a few new powers when we met Pacifica and Gideon and we don't even know who the 'super alpha twin' is." answered Dipper.

"I'm the super alpha twin!" stated Mabel angry.

"It's still a mystery!" rebutted Dipper.

"Whoa whoa, calm down kids." said Stan. "If you get angry again you could destroy the shack."

"Yeah you're right." agreed the twins.

"Okay, then we now know what we're gonna do now." said Stan. "It's time to figure out your advantages and disadvantages, and I know just the place where we can find that out."

"Yay!" shouted Mabel.

"Oh no." said Dipper, lowering his head.

Gleeful's Residence

Meanwhile, with Team Pacifica, Pacifica and her friends were checking the image Gideon gave them and then compared it to the image in the sign outside of Gideon's house. The two images were identical.

"Told you I knew where it was." said Pacifica's redheaded friend.

The three girls went to the door and Pacifica knocked. After a few knocks, they were greeted by Gideon's father, Bud Gleeful, after he opened the door.

"Well hello there, little girls." greeted Bud. "Is either one of you Gideon girlfriend?"

"Blegh! Don't say that." said Pacifica in disgust. "I'm here to talk with Gideon."

"Oh, you're the one he wants to tell about... the crystal, isn't it?" asked Bud. The three girls replied with a nod. "Follow me then, he's been waiting for you."

The three girls went inside and Bud closed closed the door.

Gideon's Room

"Gideon, you girlfriend and her two friends arrived." called Bud as he opened the door of Gideon's room.

"I'm not his girlfriend!" stated Pacifica.

Pacifica and her friends went inside as Bud closed the door. The lights turned on to reveal a desk in the middle of the room and two chairs, one disoccupied, and one where Gideon was sitting. After Pacifica sat down on the disoccupied chair, Gideon started the talk.

"You remember the twins, right?" asked Gideon.

"Yeah, those two pests who ruined my family." said Pacifica, her anger rising.

"What?" asked Gideon.

"Nothing!" answered Pacifica, realizing what she just said. "Anyway, what did you wanted to talk about?"

Gidoen took out his '2' book from out of nowhere and passed it to Pacifica. She had no idea what Gideon wanted her to do with that book, but once he simple said 'open it', she grabbed the book and did what Gideon told her to do.

"This book has a page that describes a crystal hidden in the forest that can transform somebody into a super form, an even stronger version of themselves." started Gideon as Pacifica founded the page and started to read it. "Ever since I saw that page, I dissmised it as a hoax. But after seeing the twins on the super forms the page describes, I'm afraid it wasn't a hoax at all."

"Tell me something I don't know." said Pacifica, still reading the page.

"We can get that power for us." said Gideon.

After hearing those 7 words, Pacifica closed the book in an instant and gave it back to Gideon.

"Continue... you catched my interest." said Pacifica, sporting an evil smile.

"Here's the plan, we both enter at midnight to steal that crystal from the Pines, and then we'll both take some energy from it to gain our super forms." explained Gideon. "Afterwards, we catch the twins when they are in their normal forms and we finish them off before they can do anything!"

"I'm starting to like this." said Pacifica.

"But there are a few conditions." added Gideon. "We get the crystal and gain super forms, but I'll destroy Dipper Pines, while you knock out Mabel and send her to me. After I have my 'fun' with her, you may destroy her as messily as you wish."

"That's so horribly evil... I like it." said Pacifica in a playful tone.

Pacifica's friends, meanwhile, just waited on a wall for the conversation to end, hearing every word they said. They got increasingly scared the more horrible and evil the conversation sounded.

"Deal?" asked Gideon.

"Deal." answered Pacifica.

Pacifica and Gideon did a handshake as Pacifica's friends looked at each other with worried looks.

"Those twins will never see what hit them." said Gideon and Pacifica in unison. "Hey you're ripping me off again!"
