Grinning like a homicidal maniac, I withdrew the seventh and final device from the sports bag. The Taserlike little number wasn't even of my devising, but the creation of somebody with far too much time on his bloodied, gore-soiled hands. I waved the small electronic device in my sister's direction as I spoke, this time with a perfect blend of hateful anticipation and joyous conversation.
"See this, Gaz? Remember it?" The broken demon I used to call my sister paled considerably, her eyes bugging out almost like Zim's. She shuddered, finally able to move since the twin sentinels of mine had released her from their cold steel grasp.
"No...no, it can't be..." She stared at it like one would stare at an swarm of angry hornets. I smiled.
"Oh, yes it can be, Little Gaz!" My smile grew wider as I forged on. "Rule Number One of Professor Membrane: Never discard plans to old inventions." I had once stumbled upon Dad's old invention archives, and soon discovered the perfect tool of devastation and domination over all human life forms. Gaz knew as well as I what exactly I held in my hands. The Forbidden Weapon. The Taser of Thanatos. But we both knew what our father's real name for the weapon was.
She whispered it, as if she still couldn't believe I had thrown one together.
"The Death Probe..." Gaz stared at me as if I had suddenly turned into an Irken before her eyes. "Why..."
"Why? To ensure that you would remain where you belong: firmly under my heel, Little Gaz. I even modified it a little bit." I held the Death Probe's electrodes to my arm and pressed the button. Gaz cringed in fear of the gruesome sight she would be treated to, but nothing happened. I grinned ferally.
"It doesn't work on me. And it won't work on any other life form you try to use it on...except you..." I held the Death Probe aloft, then thought of something better. I switched it on, and made short, mocking passes at Gaz's broken body. She cringed in fear of the horrible pain the device delivered, but I never once touched her. I snapped my fingers, and the robot sentinels held her aloft once more.
"You remember the story, don't you?" When she nodded in stark terror, I continued. "Dad always was one to play both sides of the coin. The world falls into chaos without him, but he can play Death better than any other deranged leader of the Earth.
"He made a device that would deliver a stimulated signal to the target. The organs would liquidate themselves quite painfully, then the body would melt into a mass of organic sludge and blood. Bladder and bowel would spill as the victim died of an electronically stimulated Ebola like reaction within less than thirty agonising seconds."
I clapped twice, and one of Dad's hover screens came into view. "I even recovered the supposedly lost videos of his tests on human guinea pigs...the condemned criminals of older times..." I moved to hold my sister's eyes open as she witnessed the terrible power of the Death Probe at its finest. Ten minutes later, she was dropped back onto the floor, sobbing with pain and misery. I decided that the final test was upon us.
"Do you swear to me that I am your lord and master, to be obeyed whenever I demand? Do you swear to me that your worthless life lies crushed beneath my heel?" She stared up at me, the spark of rebellion flickering out. I took the club and, setting it back to lightweight, smashed her head with the very end. "Well, Little Gaz? Do you swear to me that I have won at last?"
"Yes..." The muttering was too weak for me, so I stomped on her legs, hard. "I didn't quite catch your responce, Little Gaz. Once again, for the record?"
"Yes...my master..." A sinister laugh escaped my throat as I screamed in joy and success.
"Yes! Yes! YES!!!"
Finally, my long and painful war was over. I was free, as free as any human could possibly be. I had crushed my tormentor utterly. I doubted that she would ever question my motives again. As I began to clean up the disaster in the living room, paying careful attention to erasing all traces of evidence, I muttered to Gaz mockingly.
"Remember, you promised...Don't ever forget that I won, Little Gaz..."
