Zim Leaves earth to go back to earth only to be put through years of nonstop training. But he had left something on earth. Gir. He soon forgot about his dysfunctional Sir unit. He was not twice as good as any invader out there and he was to take earth for Irk, for real this time. Dib yet again starts to try and stop him, but Zim is more powerful this time. Zim starts using an invention of his own, controlling everyone in town's brain, Dib is the only one who can resit it, but will he be able to for long?
