Zim awoke on the floor in pain; his arms and legs had been bound together with coarse rope. He wanted to thrash around and scream, how dare the humans try to incapacitate him. A dark laughter filled the church hall, followed by thunderous applause.

"Ladies and gentle men!" Membrane called, "We are so fortunate to have a priceless opportunity within our grasp!" The gaggle of humans who had stuffed themselves into the pews murmured in approval. Zim took the brief pause in the scientist's rant to get a firm grasp of his surrounds. An old iron chandelier illuminated the small dark room. Grotesque tapestries hung on the red wood walls, drawing attention to the front. A gaping hole had been carved into the floor, emitting thick coils of smoke. The wide harvest moon bathed the room in an orange tint through the cracks in the ceiling. Membrane grinned at his audience and gestured to the tangled alien on the floor. "Today a noble sacrifice has offered to give up his life in order to end this nightmare once and for all!"

Sacrifice? Zim was nobody's sacrifice! He wanted to shout, but he kept quiet. There had to be a way out of this. While the evil human continue to rant Zim he reached behind him, hoping to find the knot that kept him bound in place. Pain shot through his right arm. Blood pooled in slowly behind him, he had cut his hand on something. The knife! He still had the knife from the carnival. He began the tedious task of sawing away at the coarse fibers.

"…my son's perception of our world will finally come to an end!" Zim's eyes widened. …Dib's perception? This whole time that he had been running around he had been dealing with Dib's view of the world! That was the last straw. Sick of this planet, sick of running around and dealing with this insane world; Zim sliced through the ropes.

"Zim will not be your sacrifice." Zim growled, turned to face the crowd and froze, seeing Dibs emotionless face among the crowd. "YOU! What are you doing!?" He stalked toward the human. "How could you let this happen!? After everything-"

"Now, now," Membrane soothed, "this is, after all, for the greater good."The scientist restrained Zim by the arms as Dib wordless approached.

"I don't care about your greater good you filthy pathetic human!" The human boy took the knife and cast it into the fire. He reared up his legs and kicked Dib square in the jaw. As he writhed, he could heard the clicks and whirs from his PAK fighting the gummed up compartments to try and defend him. Two spider legs jumped out of his PAK, straight through the scientist's rib cage.

"I thought you disabled it." Membrane sputtered through a mouthful of blood.

"I'm trying." Dib scowled. "I just need you to give me full control."

"Never!" Zim retracted his PAK legs. " Zim's going to leave this pool of filth behind and there's nothing you can do about it!" He sliced through Membrane's neck like it was butter and gave the gasping scientist a gentle push on the shoulder. The human tumbled backwards, red gushing down the side of the deep hole. A loud thud came, and flames crawled up the sides of the tomb. Zim watched the human writhe with dull eyes until the human ceased his struggled screams. He turned and faced the crowd that huddled together in the pews. Blood flowed freely from his sliced hand, his left arm throbbed, but still he glared menacingly at the terrified humans. "If any of you even dare to touch Zim, I will not hesitate to slaughter you as well."

Ash poured down in the church, and the shrieks of winged beasts grew closer with each second. His head pounded as he walked over to where Dib stood in deep concentration."This is all your fault." Zim muttered darkly. Pain shot through his hands and feet as the tips of his fingers tinted black, shooting dark blue veins up his arms. The coiled and compressed, trying to restrict his movements.

"I'm sorry dad." Dib sighed as Zim shot a PAK lef deep within Dib's chest. The alien let out a shrieking laughter. Red blood ran down the arms, Zim marveled at it, how the strange liquid mixed so beautifully with his own. He held hand up to the light, watching how the harvest moon glimmered off the life giving elixir. The wound given to him from the wolf throbbed, as pain pulsed through Zim's body.

He looked at it as it festered, and dripping thin trails of black ichor down his arm. His head pounded more, begging him to rest, but he couldn't stop. He had to see more of that wonderful red color. He pulled out the silver blade and stabbed Dib once again. His limbs started to feel numb, an electric delight shot through him as he saw more of the red cascade from Dib's body. He inhaled deeply; a sweet aroma filled his lungs.

The smell of death.

He turned and looked again at the people in the stands, each one of them was full of alluring red, all he had to do was bring it to the surface. A grin split across his features.

"Who's next?"

His eyes snapped open; he heard shouts from above in where he laid. Florescent lights reflected of the linoleum floor casting an unnatural glow about the room. There were people in bio-hazard suits running around an operating table in a panic. Something on it was writhing and releasing strained screams that sounded all too familiar. Alarms kept ringing, only to be silenced periodically. Blood decorated their clothes and the walls. He watched as a man with goggles was being bandaged at the edge of the room.

A strange lethargy clouded his mind as he sat up, pain shooting through the haze as he noticed a collection of purple wires embedded into his arms the nape of his neck. Someone helped him to stand, sputtering garbage he couldn't quite make sense of. Now on his feet, he could see a little green body pealed open on the gurney.

His first instinct was to vomit, seeing his own body defiled and screeching like a mindless beast. His eye implants were shattered on the floor, and every bloodied PAK leg had been ripped out to prevent any other humans from getting harmed. The alien's intestines were stretched up to the ceiling on hooks, to see how far they could stretch before being removed. The organs twitched and convulsed with each ragged scream, as Zim realized he was physically tethered to his old body by the PAK's wires.

"I thought you were an expert on this thing," Membrane looked at him, "what are you doing?" Zim calmly picked up a discarded scalpel and plunged it into the sobbing wreck his body had become. His head pounded as the last of his data transferred into the new host his PAK chose.

"It was suffering." Zim froze. That was Dib's voice. He had Dib's voice. An unbridled rage filled him as he gripped the scalpel tight and severed the wires that held him in place. "You horrible vultures!" He attacked the first person he could get in arms reach and snapped their fragile necks. "What have you done with Zim!?"

"This was your idea." Membrane turned to mutter something to his assistant, but it wasn't enough to stop his rampage. "This isn't the time for a fit of the crazies, you have to pull yourself together son." Zim grabbed on of the suspended PAK legs and used to spear the assistants that rushed to contain him. This body wasn't made for long term combat, but he would push until he had the scientist begging for mercy.

"I will burn your entire planet to ashes." Zim growled as he grabbed Membrane by the ears and smashed his skull into the ground. "I will violate the lives of your children!" He slammed the human down into the ground again. "Your brain will sit on my mantel as a trophy!" He was pulled up by a security guard, able to cave in the scientist jaw with his boot before fully being pulled off the man. "You will watch as every piece of human DNA cannibalizes itself under the reign of the Irken Empire!" Like a starved beast he clawed his way to the scientist, hardly flinching when the sedative pierced his hand. Membrane watched mournfully as the guards restrained the form of his son against his will.

"Sir, we need to get you to the med bay, now." Membrane was ushered away from the screaming child, knowing in his heart he couldn't protect the boy from the storm that was coming.

AN: You have gotten the bad ending, you would have been scared by some of the things that happened and would have made some mistakes. All in all you would have made it out of there alive.
Each one is a little different and reveals a little more about the world that Zim was wandering through the first nine chapters so feel free to read the other endings.
