It was a sunny afternoon on the filthy planet known as Earth as a young girl walked home from middle skool. suddenly there came a loud crash right beside her. Thinking it was important she turned her head only to find it was the green kid who lived 2 houses over. He was lying on his back, the black top having a long skid mark.
"Damn you Dib-stink!Must we do this everyday?!" The green boy known as Zim said recovering from the dramatic entrance. From the smoke came Dib. A large headed teen with a nasty fixation on the paranormal. "Until everyone knows your an alien i will never stop hunting you!" Dib replied in his usual 'save the world talk attitude.
The girl sighed & watched as the 2 idiotic teenage boys fought each other. A cute magenta haired girl with amber eyes walked next to the girl that was never on the original show, holding a gameslave 3 device in hand. "Dib,hurry the hell up. Killy the Klown is coming on in 2 hours." The girl known as Gaz exclaimed bored.
"Yeah, whatever, just give me a moment." The big headed guy replied as some metallic tentecle came from brhind his back."After years of studying your PAK I've finalaly created one of my own!So meet your match zim!" He exclaied proudly producing not 1 but several bladed tentecles & sider like apendeges. " Hahahaaha! Foolish human,
do you truly believe you who has only had a few earth weeks training, can amount to the years of using suppior irken technology to a cheap knockoff from such an inferior race?! Ha, that is pure comedy!" Zim bousted. "Hey dumbasses, mind stopping the foreplay and tear at each other's pants already?" Gaz exclaimed angrily.
And so began the weekly transformation from cul-de-sac to battleground! Dib rushed at zim, tentecles flowing behind him, zim aranged his weapons in a shield like position. Dib striked with a pointed appendage, zim grabbing it with his thingys, tossing dib onto his back creating a crater wear he landed. Zim used his spidder legs to launch himself in the air aiming the arachnid limbs to pierce dib's chest. Dib had noticed this and quickly rolled out the way as zim made impact!Dib shot another tentecle aimed at zims face, zim caught the sharp weapon and pulled dib into a hard roundhouse kick his connecting to his jaw. The fight turned into a fist filled brawl as the teens fought with crazy martial arts moves. Damn, those cats were as fast as lightning!Dib kneed zim in the jaw as he propelled himself into the air landing behind zim as he turned to face his nemesis."Let's end this!" Dib exclaied cracking electrical currents through his PAK."Agreed dib-human!" Zim replied sparking flames across his PAK! The 2 dashed twards each other, each with fury in his eyes! They launched into the sky, bringing their metal instruments of doom and fists crashing creating a huge explosion turning everything in your sight white!
