I laughed long and hard, not at all afraid that Gaz's shrieks of pain would upset the neighbours. They were used to the sounds of my own pain at my sister's hands, after all. They would barely notice her own soul wrenching scream. I reached into the sports bag and withdrew a long black club, the fifth of my seven devices. As I lifted the weapon from the bag, Gaz's eyes seemed to widen in what might have been terror.
The two robots holding her fast, she couldn't even so much as shudder in fear. I slapped the club in my free hand in the classic move of menace, and stepped forth, the biggest shit-eating grin in the history of mankind on my face. The stupid bitch didn't know how much pain I was about to place her in.
"It's been fifteen years since I got a break. And I would think that everybody's entitled to a break from pain and suffering. Don't you think the same way, Little Gaz?" I smiled wider. The anticipation of showing her what true pain was transcended mere human emotions, a delightful high of release that I couldn't get enough of.
"Of course you don't." I continued without pause. "You wouldn't know kindness if it approached you in the street and smacked you across the face." I raised the club, turning a small dial on the side. The club grew lighter in my hand, and I slammed the club into Gaz's left cheek. She cried out with the pain.
"So I think it's time that I took my payment for your bullshit out in full, Little Gaz." I smacked her across the right cheek, then left once more. With each blow, her resolve seemed to crumble a little bit, until at last she was openly weeping. She spoke words I didn't think she would speak so soon.
"Why, Dib...why are you...doing...this...?"
I snarled in her face, full of rage and pure boiling hatred "BECAUSE YOU PUT ME THROUGH ENOUGH OF IT YOURSELF, BITCH!" I turned the club's dial in the other direction, and slammed the now very heavy head down on her left thigh. She screamed in pain as her femur was broken once, twice, three times by my weapon.
"You put me through more pain and suffering than Zim could ever hope for!" Another three or four blows, and the bones of her thighs were nothing more than shattered fragments. I landed blow after blow upon her legs, crushing the bones into calcified jelly. As the muscle and skin finally collapsed under the onslaught into nauseating organic detritus, I raised the gore-covered club for another blow. Then I heard the sound of pain filled tears.
"Please, Dib...no more...please...no...more..." Gaz's tearful plea for mercy was noticed. Oh, it was noticed, but it fell nevertheless upon my deaf ears. To show mercy at this point was to show weakness, and I was through with showing that to the demon beast that lay with its legs destroyed before me.
"I don't think so, Little Gaz. I'm not done and through with you yet. Oh, no, not by a long shot..." Dropping the bloodied and gore-soiled club on the floor, I took out the sixth device from my bag of tricks. The small collar looked just like the hall pass Zim had been given during his horrible dark harvest of the skool. I placed the collar around my sister's neck, and stood back as it shrank. Just large enough to let her breathe, but small enough that she could never remove it without my express permission. And, of course, it looked like a choker to anybody that took a close enough look. Perfect for my needs.
"I don't think that you'll be telling anybody about our little talk, dear sister. I wouldn't want the world to think that I've broken you so easily." I snapped my fingers, and the two robots dropped Gaz to the ground. "Go ahead, Little Gaz! Go and call for help!"
She barely uttered the phrase "Help me" before she stiffened with the shock of electricity the collar had delivered to her. Gaz took the collar's sides into her hands, disbelieving what I had just done. At long last, it appeared that I had won the battle against the True Enemy.
"Wasn't that neat?" I snickered while she whimpered. "It can even calibrate itself to prevent you from ever telling somebody else about this. And every time you try, the shock gets longer AND more powerful!" I laughed with bitter derision. Was she going to gamble on her fate? Was she going to try and call my bluff?
"And if you try and hurt me ever again, I have a little surprise for you that should shut you up for good..."
