1. One of the few good shows that ever aired on Nickelodeon. After it was canceled Nick just went downhill from there. It was canceled because some idiots got ticked off because they felt it was to dark and didn't recognize it for the genius work it was.

2. The meaning of life!
OMG Invader Zim is proof that there still may be hope for t.v. out there! Jhonen Vasquez is a genius!

The greatest televison animation to hit the Earth. Invader Zim is also the named of the main character, a doom-bringing alien who is 'very small.'
"No Invader has ever been so small... you're small Zim... you're tiny..."

The greatest cartoon show ever made. Still airs on Nickelodeon every once in a while (frequently the first episode), but is aired every day on Nicktoons, usually more than once per afternoon.
I laugh at those who cannot watch Invader Zim because their family is too poor to order digital cable, yet they buy all the merchandise from Hot Topic anyway because they claim to be deticated fans.

1.) A being from the planet Irk who who was sent out on a fake mission to invade a random planet selected by his rulers, the Almighty Tallest. Is not truly an invader and is overzealous about his "mission." Stands at about 4 feet tall and has green skin, with two antennae protruding from his head and large ruby eyes. Owns a optimistic SIR unit whose name is GIR and loves Zim very much. Goal is to take over and/or destroy the Earth. Dislikes humans and almost everything related to humans. Archrival is Dib, a classmate at "Skool" who is determined to capture Zim to save the planet and become a famous paranormal investigator. Zim is based in the United States where he apparently set his residence in an unknown city.

2.) A TV show that premiered on the TV channel Nickelodeon on March 30, 2001. Created by Jhonen Vasquez, directed by Steve Ressel. Stars Richard Horvitz as Zim, Rosearik Rikki Simons as GIR, Andy Berman as Dib and Melissa Fahn as Gaz. Was cancelled in 2002, but completed episodes were released on DVD in 2004.
1.) "Invader Zim, signing off!" - Zim
2.) I like the show "Invader Zim".

Possibly one of the darkest (and one of my most favorite) cartoons on Nickelodeon.

Of course, it was canceled because Nick needs MOAR time for shit shows like iCarly.

Totally logical, amirite?
Nickelodeon's view:

Invader Zim = Dark
Dark = NOT PREPPY
Dark = BAD!!!

*cancels show*

Most other people's view:

Invader Zim = Dark
Dark = NOT PREPPY
Dark = Good!!
