Narrator: Ah, summer break.
As a hot summer sun shines down on a family having a nice grill out, as two kids were playing.
As the man ask. "So you want cheese on that, hon?"
"Sure, Hank." The woman replied.
Narrator: A time for leisure, recreation, and taking 'er easy.
A sign was seen saying "Welcome to Gravity Falls."
Second Narrator: Unless you're us.
*CRASH*
Two kids crash through the "Welcome to Gravity Falls" sign on the Cart, screaming. As they were being chased by an unknown monster, which is knocking down trees, with a sonicboom was heard, as some short of humanoid Pterodactyl with a large yellow beak-like mouth, green eyes, red skin, black and white clothing on his shoulders and waist, green braces around it wrists and ankles, and small, yellow, retractable wings that resemble a glider in appearance which are connected to a 'jetpack-like structure' on it back. On the left shoulder was some kind of 'badge.'
"It's getting closer!" The girl exclaimed looking back.
The monster tries to catch the cart but just falls short. The cart flies off a rock and lands roughly. As the humanoid Pterodactyl use some kind of energy whips at the monster, who try to smack it out of the way.
Narrator: My name is Dipper. The girl about to puke is my sister Mabel. You may be wondering what we're doing in a golf cart, fleeing from a creature of unimaginable horror. While a humanoid Pterodactyl was helping us.
The monster throws a tree in their path.
"Look out!" Mabel warned his brother.
"I got ya! SQUAWK!"
The humanoid Pterodactyl grab the two kids, as it froze, with the two screaming.
Dipper: Rest assured, there's a perfectly logical explanation for this.
Second Narrator: But, let's start from the beginning.
-One Day Ago, In Space-
A big ship red and gray was seen shooting red laser at a small one blue and green ship, as the small ship fire green laser right back.
On the big ship, red drones were seen as one say. "Hull damage: 20 percent, weapons system's still operational."
A humanoid creature with a face resembling that of an octopus. He has tentacles dangling in the front of his face, like a beard. His skin is pale-green with yellowish spots on his face and tentacles. He doesn't have a nose and a visible ear. He has red eyes. The humanoid creature wore a black and red-brownish armored suit and gloves. His armor is spiked at the shoulder and arm pads. He has green sacs on the sides of his head with black lips.
"I have come too far to be denied." He snarled. "The Omnitrix shall be mine, and there is not a being in the galaxy that dares stand in my way."
-One Day Ago, North Carolina, Piedmont Elementary-
A young boy around 10 with spiky light brown hair and hunter green eyes, he wear a white hooded jacket with green stripes on both arms and a green number 10 on the right side (that Ben Prime wear) With tan cargo shorts and black sneakers with green cybernetic on the sides. This is Kennedy Ken Pines.
He currently making an paper airplane, as he threw it at his teacher, who gasps and look at Ken, who quickly poorly pretending to read his book, smooshing his face in between the pages.
The teacher look at Ken.
As Ken look at the clock, ticking.
*Tick*Tock*Tick*Tock*
'Come on, hurry...' Ken thought while looking at the clock.
"And I just want to remind you all that I will be teaching summer school this year, and it's not too late to sign up!" Ken's Teacher told them.
'Psst... Yeah, right.'
*RING*
"Finally! Outta here!" Ken cheered.
"Everyone, have a good vacation, and I hope to see you all again in the fall." Ken's Teacher said, as Ken was about to leave. "Kennedy."
Ken was so close, as he look at her, to see her held up his paper airplane. "A word with you before you go?"
Ken groans and walk over to the his teacher desk, for his scolding.
-Meanwhile, Outside-
Three kids were near some trees, as two of them are older. The first one is a slim tall kid with black hair wearing a black shirt with a skull (Duncan from Total Drama) with blue shorts and black and gray sneakers.
The second is shorter, with round glasses with a open button brown shirt over a white shirt, with gray pants and white shoes.
These two were Jacob Nelson and AJ Froud, as they confronted a kid name Frank wearing a blue shirt and green shorts with blue shoes with white circles on the sides.
As Jacob told Frank. "Normally, we'd take your money and beat you up. But since it's the last day of school, we're going to give you a break." As Jacob grab Frank shirt. "Now fork over the cash, so we can get out of here."
"Leave him alone!"
They turn to see Ken, glaring at the two.
"Get lost, shrimp." AJ said.
"I said, back off!"
Jacob smirked. "Oh, looks like we got us a hero. Suppose we don't wanna back off?"
"What are ya gonna do about it, Pines?" AJ wondered.
Ken and Jacob stare intently, as AJ look at them intently as well, as Ken run towards the two bullies triumphantly. But...
The next minute, Ken and Frank were hung up on a tree branch.
As Frank sarcastically say. "Thanks a lot, Pines."
"I was just trying to help." Ken said.
"Next time you wanna play hero, make sure you can back it up."
Ken sigh and hung his head down.
*BEEP*BEEP*
The two heard a car beep and saw a orange minivan.
"Come on, Ken. Hurry up and get in. Dipper and Mabel is in the van too." A young man with brown hair was seen wearing a white dress shirt with black pants and dress shoes. This is Phil Pines.
"Uh, Dad? A little help here?" Ken said.
After getting Ken down, Ken went in the van and say. "I have so been looking forward to this!"
Ken then notice and look next to him and saw a girl around his age, as she has long light brown hair that reach her back a purple clip with a picture of a cat, as she wear clothing (Like Diana from Martin Mystery) a long-sleeve lavender shirt with purple sleeves, light blue jeans that reach to her knees and white sneakers. This is Diana Pines.
"What are...? What are you doing here? What is she doing here?" Ken wondered why his cousin was here.
"Take it easy, little bro. This wasn't her idea. Somebody convinced her mom that 'going somewhere for the summer would be a good experience for her.'" Dipper explained.
"He's right, doofus." Diana said. "This isn't my idea."
"Come on, bro-bro! I'm glad she here with us." Mabel told them. "Besides. We're pack to go visit Grunkle Stan!"
"Wait...?" Ken look in the back to see four bags and realize... "Dad, please. Tell me you didn't?"
"I thought it would be fun if you four go to your uncle in Gravity Falls this summer. Is... that a problem, Ken?" Phil asked.
"No..." Ken sigh.
As Phil drive to the Airport, Dipper was reading a book, Mabel was looking at the van window, as Ken and Diana look has their heads turn.
As Ken say. 'Aw, I can't believe it. I wait all school year to go on this trip, and now the queen of cooties is along for the ride."
Diana heard what his doofus cousin said and shot back. "Hey! I had my own vacation already all planned out too, you know?" She then pull out her schedule from her bag. Each activity is color-coded, so I never do the same thing two days in a row."
Ken raises his eyebrows at her thinking it lame and boring.
"Now, I'm stuck with my doofus cousin going to our uncle for three months."
"Nerd."
"Doofus."
The two insulted each other before turning their heads.
Ken look out the window and thought. 'This gonna be the worst summer ever...'
-In Space-
In Space, the red and gray ship is still attacking the blue and green ship, blasting lasers into the hull of it.
As the drone say. "Their propulsion systems have been destroyed."
"Prepare to board! I want the Omnitrix, now!" The drone master demanded.
The ship getting chased primes a laser blast and fires, directly hitting the humanoid creature's control room, blasting him across. But immediately after the warship retaliates, blasting the ship to pieces. Out of those pieces, a small pod shoots into a vortex, as the pod break apart, turning into a sphere heading to Earth.
