DOOM AWAITS ( Invader Zim x Destroy all Humans crossover / Male reader insert)

Chapter 3: Citizen (Y/N)

A few days have past since the destruction of the fair.
Zim was busy running some tests with their new human test subject for the time being.
Just some standart tests, how smart is she, what happens if you throw her in a room and then suck all the oxygen out, how many Disintegrator Ray shots can she survive.

To nobodys surprise... none.

(Y/N) on the other hand kept himself busy too. Destroying a few more farms, annihilating a few more humans and so on.
As for now, he is sitting again on the round window frame inside his quarters, the human hobby magazine again in his clawed hands,

(Y/N): "That Volcano Primarch seems really friendly. Maybe too friendly."

His thoughts are interrupted the moment his communicator goes of. Zim is calling,

Z: "(Y/N), i have a new mission for you. Meet me at the bridge."

(Y/N): "Alright, big Kahoona."

The tall Irken Invader stands up and walks out of his room. He really hopes that this mission is not a undercover or scouting mission again. He hates it being undercover. Those undercover/scouting missions are a pain in his sides. But sadly, sacrifices must be made if they want to Doom this planet and save their Invader comrade.
He arrives on the bridge with GIR looking at the monitors like hypnotized and Zim looking at the holographic world map at the middle of the room. Zim has his index claw at his chin, (Y/N) knows what that means. His standing now right beside his "little brother",

(Y/N): "What are you thinking about?"

Zim points at a location on the map,

Z: "This small Town near the Fairground you have destroyed, shows a high Level of Radioactive radiation. Those humans are up to something, i just know it."

(Y/N) looks down at Zim,

(Y/N): "Let me guess, you want me to investigate."

Zim looks up at him,

Z: "Indeed. I will try to find the source of it and then give you further instructions once you reached your destination."

(Y/N) nods, and then made his way towards the Hangar.
He has no idea what is going on down there. But whatever it is, he will blow it up.

Rockwell, USA

4:00 PM

(Y/N)s Spacecraft lands on a Farm wich is located near the outskirts of Rockwell. He exits his Saucer and Zim is on the comms again,

Z: "(Y/N), i think i found the source of the radiation. Those nearby bovoids appear to have been genetically manipulated by the humans! But for what purpose? I want you to investigate this bizarre, mutated species."

(Y/N): "Tests on animals? What are they trying to accomplish? Create living Nukes?"

(Y/N) hides himself in the field and activates his scanner, let's see what those humans are up to. A weird green glowing cow walks past him and the Irken Invader scans the mind of the now mutated creature, and what he found is... a bit weird.

Cow: "Moo... er... Brains!"

Zim got the results of the cortex scan not a second later, and comes to a conclusion,

Z: "Brains? Healthy green glow? Those human fools! Clearly they've genetically altered these pathetic gasbags and turned them into RADIOACTIVE EXPLODING ZOMBIE COWS! Show them the folly of their MAD SCIENCE!"
