Two weeks later, the base had been fully assembled. Like most human domiciles, it had the essentials for survival and comfort. A pair of Irken androids served as MiMi's decoys, and the SIR Unit herself had taken to using her cat disguise. With the wire fitted into her logic circuits and her eyes now a cobalt shade of purple, she looked for all the world like her mistress turned into a robot. Her stabilisers had been recalibrated to Earth's gravity well, and her left foot had been fully repaired.
Beneath the house was a maze of alien corridors and lab space. Each room housed numerous transmitters, inhibitors, logic systems and other assorted machinery that would eventually form the core of MiMi's ingenious plan to conquer the Earth and subjugate its life forms. Yet there were more supplies she needed, and the curse of shipping times was one that weighed heavily on the SIR's mind. She found herself, then, with much time to plot Zim's demise and that of the miserable children of Membrane's. The Irken and his human accomplice had destroyed Tak's plan, but MiMi harbored a special hatred of Gaz, the one who had worked with that horrible robot GIR and dominated her mind. Oh, how they would pay with their blood and lives!
The schematics for the device she needed were prominently displayed on several screens, and the operation of the device would have boggled the minds of the smartest of humans, and perhaps the smartest of Irkens. But MiMi was a robot, a SIR Unit, and the intricate plan took perhaps a mere fifteen per cent of her total logic processing to fully understand. With this doomsday device, the SIR Unit would be able to take the human homeworld without a single Irken life being lost. As MiMi double checked the supply list and made slight improvements to her device as the needed items came in, she laughed chillingly. The humans would be none the wiser, and she would have her vengeance at long last.
"Soon, soon the humans will suffer the pain of betrayal, and they will fall like autumn leaves to doom of their own making!" MiMi's voice had regained its original timbre, but the disaster which had claimed her mistress' life still weighed on her vocoder and mind alike. She turned to the lone suspension tank, in which Tak's defunct Pak was being slowly recharged. The Pak was needed to complete the loop and assure MiMi's control over mankind's fate. She laughed again.
"Sleep well, miserable humans, for your days are at long last numbered. Soon, I shall rule over you all, and nothing you do shall impede my progress..." She paused, looking at the recharging Pak with longing in her eyes.
"Don't worry, my Mistress. I shall avenge your death and bring honor to your name..."
