Character Profile: Zim

Born into the Irken Empire, Zim trains hard to be an invader. The Irken leaders Tallest Red and Tallest Purple banish Zim off to Food Courtia due to him destroying the original plans for Operation: Impending Doom 1. After seeing the resigning in the restaurant he was working at, he flies to Conventia where all the other Irkens were heading.

After he made it there and scared the Tallests with him showing up, they set up a plan to get rid of him. They send him to a planet "that is so secret that no one dares speak it's name". Zim lands on Earth in his vootrunner with his robot SIR unit GIR. After landing they create disguises for themselves to blend in and enroll in Skool (and no, that is no typo).

Only one person knows what Zim really is and that's Dib, a junior paranormal investigator who is in his class.

Ever since then nothing on Earth and in space has been the same again....
