The Triplets' Guides (Reader Insert Version)

(y/n)'s Guide to Mystery Rays

Suddenly, the door to the shed was flung open, and (y/n) turned to see Dipper and Mabel, standing with equally determined expressions on their faces.

"(y/n)!" Dipper shouted over the howling wind. "You have to stop!"

"What?" (y/n) shouted back, putting a hand behind one of her ears and leaning closer so that she could hear him over the storm.

Dipper took in a deep breath, and started to scream at the top of his lungs.

"I SAID, YOU HAVE TO STOOOO..."

Mabel shut the door so that the storm wasn't nearly as loud.

But Dipper was still in mid-shout.

"...OOOP!"

(y/n) yelped in pain at his shrieking, high-pitched screaming, and covered her ears.

"Oh great, now my ear drums hurt as well as my throat."

When she had gotten her hearing back, she looked back at her siblings with a malicious grin.

"Well, you're too late!" she cried, gesturing towards the energy level bar on the machine. It was about halfway up. "Once my machine is at maximum power, it will give make everyone's worst nightmares come to life, and I will rule supreme over all the raging chaos!"

But neither Dipper or Mabel looked remotely surprised.

"You invented an evil ray and shot yourself with it, didn't you?" said Dipper.

"Yeah, that sounds about right" Mabel added, before turning towards her brother. "How long do you think it'll last this time?"

"If it's anything like last time, about ten minutes" said Dipper. "For now, let's destroy the doomsday device before we get charged for overuse of electricity...again."

(y/n) stepped up and puffed up her chest.

"I'd like to see you try, but if you wanna get to the machine, you'll have to go through me first!"

Dipper threw a punch at her, aimed at her stomach, but his fist went right through her body and out the other end.

(y/n) grinned.

"And by that, I mean quite literally."

She phased off of his arm, before turning off the intangibility belt, and taking out the plasma gun from her tool belt and activating it, the light from the electricity illuminating half of her face as she glared at him with a dark expression.

Dipper looked up at her.

"I'm pretty sure that this is the part when I run."

While Dipper was screaming as (y/n) chased him, dodging her plasma blasts that missed him only by a few inches, Mabel was making her way towards the doomsday device to try and find a way to shut it down.

However, the corner of her eye, (y/n) noticed.

"Not so fast!" she said, pulling the net gun out of her toolbelt and firing at her sister.

Mabel cried out in surprise as the net entangled her body, pinning her to the shed wall.

Dipper tackled (y/n) to the side, initiating their fighting once again.

He managed to grab the plasma device and throw it across the ground, out of her reach, only for her to pull out another blaster from her toolbelt.

She pulled the trigger, and a tennis ball was launched out the end of it.

(y/n) was a bit disappointed at first, until it hit Dipper square on the cheek. He yelped in pain, rubbing the spot where she had hit him, which was starting to turn a bright red color.
