• The Nightmare Begins •
This is the pilot episode explaining how it all started. The Irken race, are gathering on the convention planet[Conventia] to discuss their invasion plan, dubbed "Impending Doom II". The first plan (Impending Doom I) was savataoshed by Zim because he did not relize he had not left his home planet[irk] and started accidentally destroying. As punishment for this, he was banished to forever prepare food at the planet Food Courtia. When he heard about Impending Doom II, he quit his banishment and came uninvited to Conventia to be assigned to a planet. The Almighty Tallest, leaders of Irken Armada, sent him to a 'Mysterios planet'[Earth] just to get rid of him. They used old robot parts, paper clips, rubber bands and other unkown things to make a robot slave for him, to not waste good robot slaves on Zim. So Zim set off to conquer a planet, which happens to be a human dirty scum ball. He disguises himself as a human, and his robot GIR as a dog. He literally plants a house and attends the local skool in order to find out more about the humans. Only one boy, Dib, sees through ZIM's disguise, but the other children do not believe him. Dib vows to reveal the truth about Zim to the other humans.
