The series revolves around Zim. He is part of the Irken army, an extraterrestrial race devoted to conquer other planets and races, the supreme leaders of Irk (The Almighty Tallest), gave Zim the mission to conquer earth with the hope of getting rid of him, so he won't interfere with the mission "Operation: Impending Doom II", since Zim ruined "Operation: Impending Doom I"; to make it look like a real mission, they even gave Zim a S.I.R. (a small robot unit made to assist Irken Invaders ), though Zim's S.I.R. is a dysfunctional robot made with pieces found in the garbage which calls itself G.I.R. (though he doesn't know what the "G" stands for).
On Earth, Zim found his greatest obstacle to accomplish his mission and a continuous menace, a preteen boy called Dib , he will try to stop each of Zim's plans and expose his alien nature to the society.
Main article: Zim
Zim is the main character of the series. He is an outcast on his own race, even though he doesn't realize this yet. Zim is quite smart, but he seems to lack any common sense. He is also megalomaniacal and conceited. While out in public, depending on what he's doing, he uses a very simple disguise.
The three-part series finale, would have had Zim returning to Irk to save his people and civilization from Dib and his forces (along with a returning Tak), with Invader Skoodge and Gaz's help. He would then become Irk's next Tallest, with Gaz as his consort.
Main article: Dib
Dib is an extremely smart boy, who won't stop until exposing Zim as an alien and therefore, proving he is not crazy. He is often mocked about having a very big head.
Main article: Gir
Gir is Zim's dysfunctional S.I.R unit, often doing and saying very random things. It often interferes more with Zim's plans instead of helping him. Gir enjoys watching T.V., often uses a green dog disguise.
Main article: Gaz
Gaz is an anti-social girl who is Dib's younger sister. She knows that Zim is an alien, but she won't do anything about it since she considers him too stupid to conquer Earth.
