(y/n)'s Guide to Mystery Rays

"...you can have my leftover burrito. Don't worry, it's only two months old. Still edible!"

To demonstrate, she took a bite out of it, a disgusted expression appearing on her face as she tried to make it look like she was actually enjoying it before forcing herself to swallow.

Suddenly, the mystery ray powered on, and fired a green ray directly into (y/n)'s chest.

She screamed in agony and dropped the burrito, her body glowing a bright green color before she collapsed to the ground.

Her body was smoking as she extended a shaky arm outwards, using it to help pick herself up off the ground with her back facing the camera.

"I feel...stronger, smarter...powerful."

Without warning, she suddenly started to laugh, a horrible, wicked laugh that reverberated off the walls of the tiny shed as she turned around to finally face the camera.

She suddenly stopped, and looked at the camera's lens.

"Whoa, that must have been the burrito talking" she said, clutching her stomach a little.

She then reached down, and picked up a clipboard with a piece of paper attached to it. She started to write down several of her observations.

"Now let's see. Eyesight: normal. Hearing: normal. Unusual body elongations or extensions..."

(y/n) looked down at her body.

"...none. Additional notes: a sudden urge to conquer Gravity Falls and then the rest of this miserable planet."

A wicked expression appeared on her face and a greedy smirk crossed over her features as she wrote that last part down.

Then, the expression suddenly vanished, and replaced with a knowing, bored countenance as (y/n) turned to look at the mystery ray.

"Yeah, that's an evil ray..."

(y/n) was still in the shed when the camera turned on again, but this time she looked completely different. Her hair was disheveled and stuck out in many directions, and she was wearing a tattered white lab coat with oil stains, black gloves, and a pair of science goggles over her eyes.

Her back was turned to the camera as she was working on yet another machine, except this one was of massive size. It was so tall that it actually went through the roof, right through the hole that (y/n) had made in the ceiling a few minutes ago.

"Yes, yes, yes!" she said, her voice rising with mad excitement as she finished up the last touches on the machine. "It is finished!"

She pressed the activation button on the panel, and the machine whirred to life, pure white electricity surging throughout the entire invention as the rain outside poured even louder and pounded on the sides of the shed.

(y/n) stood up and took a few steps to admire her work proudly. She pushed the goggles onto her head, revealing eyes that were filled with madness.

There was an electronic bar on the side of the machine, and the light was currently at the very bottom of it, but it was slowly rising higher.

"Once the machine reaches maximum power, I will make the nightmares of every single citizen in this town a reality, and I will rule over Gravity Falls! Then, the world will kneel at my feet!"

A bone-chilling, ear-piercing, triumphant shriek of laughter erupted from her throat, lightning flashed across the sky and thunder shook the ground from the storm outside.

Her cackling was suddenly cut off by a fit of coughing. She put a hand over her mouth during her coughing fit before it finally stopped.

"Man, all this evil laughing is really killing my throat."
