MiMi was working on one of the transceivers when GIR arrived with his newfound allies and the berry-haired pest. The SIR Unit smiled with glee. At last, her plans would come to fruition! Once she disposed of the harazaki and the human girl, the Earth would be hers to destroy as she pleased! Tak would have been proud of MiMi's ingenuity. She turned her attention from the transceiver that was part of the vast infrastructure lending CRANIAC its power, and spoke directly to the steel slave. Cobalt purple eyes bore into crimson red slits, challenging the smaller robot to defy her motives. GIR did nothing.
"You have succeeded in the task, GIR?" The SIR Unit saluted smartly.
"Yes, my Mistress! I have captured the human and destroyed her sibling. These robotic defenders are now under my control. Shall I lead them to the doctrine room?" The doctrine room, recently appended to the main laboratories, was used by MiMi for imbuing any captive mechanoids with Irken Knowledge and brainwashing them to her and CRANIAC's loyalties.
"Of course. But show our visitor to her...suite, down near the medical bay..." MiMi chuckled with queer laughter, and GIR simply dragged Gaz behind him, the freakish robot toys once belonging to the angry little girl now studiously obeying their temporary master. With seven new recruits, MiMi decided that the time had come to annihilate the harazaki once and for all.
She entered the torture chamber just as Zim regained consciousness from the torture session. MiMi smiled, a bit too readily for the Irken's tastes. He eyed her fearfully as she began assembling an elaborate construct. At one end was a fierce weapon known as a Heavy Thermic Lance, essentially a supraheated drillbit designed for cracking through heavy armour, even Battle Steel. Zim gulped in fear.
"What...is that...you don't mean to...?"
MiMi laughed gaily. "Don't mean to kill you, Zim? Of course I do! Mistress wouldn't have it any other way. And now that I have Gaz safely in my possession, I no longer need you. You are now merely a nuisance, dear Zim!" The Irken's body was positioned by the SIR Unit to align perfectly with the Heavy Thermic Lance. A long track was laid out between the Irken and his inevitable doom. As MiMi scampered out of the way, the mechanical tendrils holding the Irken fast began to move inexorably toward the shining, spinning tip of the drill like weapon.
Zim struggled, and the robot tentacles moved slower. He began to fight the progress of the movement, but eventually ran out of energy. The tentacles' movement began to increase in speed. Panicked, Zim fought a second time. He finally realised the terrible deathtrap MiMi had devised. When he struggled, he would slow. And when he hit the Heavy Thermic Lance's tip, he would struggle in agony. He would die a very slow, torturous death.
MiMi cackled in glee at her setup. A massive screen stood behind her, and she signaled for the screen to come alive. The leering faces of the Almighty Tallest loomed before Zim and MiMi, their pleasure all too evident in their eyes.
"My Almighty Tallest, allow me to present Irken Zim's execution at his own leisure. He may struggle, but in the end he will only hurt himself further. If he is of true mettle, he may die quickly. If not...then all the better for entertainment, correct?"
Red snickered. "Hey, Purple. Seventy thousand monies says Zim struggles when he hits ground zero."
The violet eyed Irken dictator grinned. "You're on!" He called to the technicians overseeing the Massive's peaceful cruise through space. "Any other takers?" The excited replies of the technicians seemed to frighten Zim into a dulled submission. Red scowled.
"Come on, Zim! Fight! Fight like you've never fought before! Seventy thousand monies are riding on this!" Zim freaked out at these words. His Tallest had bet on his death!? The short Irken began struggling to free himself, but to no avail.
Soon, the heat of the Heavy Thermic Lance spinning under full power could be felt upon the Irken's battered and bruised frame. The heat was enough to burn him from six inches away, and when the tip, spinning in excess of 12,000 revolutions per minute, finally sliced into his already tender flesh, he screamed. Zim screamed like he had never screamed before in his entire life.
The struggling commenced, and the tentacles began to slow. The drilling began to cut skin away, cauterising the wounds as it spun under the heat of Alien power. Soon shredding and burning his battered and weak abdominal muscles, the Heavy Thermic Lance began to cut cruelly into Zim's already abused squeedlyspooch. He struggled, and the pain became more intense, burning him with shame and agony. Him, of all the Irkens to ever be smeeted, was suffering a death not even the Tallest could have devised.
It took a homicidal maniac's touch and desire for vengeance to achieve the ultraviolent deed.
Finally, after what seemed like hours to the Irken Invader, but was actually only perhaps fifteen minutes of action, his vision faded. The very last thought that passed through his meatbrain before the weapon pierced through his entire body and drilled a neat, smoking hole through his Pak was this:
Odd...for some reason, I feel...good...about it...
And then, without fanfare, Invader Zim was dead, dead and gone. The final threat to the regime of the Tallest and the Irken Empire had been neatly speared through with an Alien weapon, thanks to a vengeful little robot who would let nothing stand in her way of completing the master plan her Mistress had designed, so long ago. The magma pump was impressive, indeed, but MiMi's plan held a sinister maverick undertone to it...
The very last thing Zim ever heard was the whooping cries of victorious delight from Tallest Red.
"That's seventy thousand monies you owe me, Purple...not to mention all of you idiots who thought he wouldn't fight it..."
