Wow, three fanfics and not one done... how sad... So, since I put Zim in pain, its only far I give some to Dib.
One shot, it shall not be anything more than one, so if you ask, I simply ignore...
Chapter 1-
Dib lay on the ground, motionless, in pain, he could see his life pass before his eyes, it didn't last long, mostly because he was only 12... He opened his eyes, this was his city, or, what remained of it. It was in ruins, everything broken, everyone in pain, he closed his eyes.
"...no...no..."
He wanted this to be a dream, he wanted someone to wake him from this night mare, but, it was all too real.
"MUHHAHAHAHAHAHAHAHA! SEE! Didn't I tell you this would happen Dib beast?"
"...no...no..."
"AND YOU COULDNT SAVE IT!"
he laughed harder, as though this was just a game, a stupid little game, Dib hadn't had time for games since Zim had come to earth.
"...no...I... I wont... just... die..."
"Stupid, stupid human. You're already dying!"
"... its... not that... easy Zim... I... I will... not... die..."
"And what makes you say that?"
"...My... s-superior... human... organs..."
"HA! You speak nonsense!"
"I may... be... losing e-everything... I'll never... know... if it was... t-too much... or not e-enough.."
"SILENCE FOOL BOY!"
"I... wont..."
"YOU ARE!"
"...d...die..."
Dib, slowly, and painfully, managed to muster a standing position, he gave this his all, felt his life flash once more, and punched Zim in the face, Zim, who didn't expect him to be able to get up, fell over, he was not prepared to get hit. So he fell to the cracked and pointed pavement. Dib managed to say one more thing-
"I... may die Z-Zim... But... it w-wasn't at y-your hands..."
And with that, he fell over, and slowly closed his eyes, they never did open again.
Zim got up, shot the body of his now dead arch enemy, and left the planet, he called the Tallests, and started on his way back to Irk, ware they had no choice, but to welcome him as a hero. The massive came before long, and killed off the rest of the survivors. The planet, due to the rain, became a large lifeless dust-ball, ware neither Irkan, nor any other race, stayed. For years it was nothing, then the Resisty came and found it, but that's another story.
Zim lived on Irk, and other than Dib haunting him in his dreams, he had a vary peaceful life.
Many years later, Zim, muttered one last thing, much like Dib did, he said-
"Dib, guess its time for, another battle... I hope your ready..."
He closed his eyes, and they never did open again.
Yeah, I have no idea ware this came from... but its vary dark and leaves on a slightly happy note, there both dead, and now there battle field is heaven, or hell, either way take your pick...
