Gaz es la hermana menor de Dib. ella es la hija del profesor membrana, pero, si la serie hubiera continuado, se hubiera revelado que ellos fueron las mejores creaciones del profesor, y que no son niños normales. Esto podría ser ovio ya que el profesor membrana no tiene esposa.


Her foul temper and love for pizza and video games makes her an unpleasant person to be near. When she isn't eating pizza or playing video games, Gaz is usually beating Dib up just for talking. Although she is typically portrayed as perpetually unhappy, her few interests have been known to coax a more positive side out of her. She usually serves as a side character, but has participated as a main character in several episodes.

Gaz, like most modern children, loves to play video games on her Game Slave, and she enjoys sketching piggies and other monsters (including pig-monsters), and is obsessed with pizza, soda, and various other junk foods. As to how she does not become fat is unknown.



She also seems to hate anyone who comes in between herself and one of those things. Examples are in the episode Game Slave 2, in which an obnoxious video game addict called Iggins took the last Game Slave 2, causing Gaz to stalk and terrorize him until he gave up the game to her. She seems to enjoy yelling at her brother, though it would seem that even that's a hassle for her.

Her biggest appearances were in the episodes Game Slave 2, in which Gaz attempts to buy the new Game Slave game, and Bloaty's Pizza Hog, in which she'll do anything to go to Bloaty's. She's also the star of Gaz, Taster of Pork, when Dib curses her to a fate of tasting nothing but pork.

Rol en Invasor Zim

Gaz is the only one, with the exception of Dib, to realize that Zim is really an alien. In the episode Gaz, Taster of Pork, she acknowledges Zim's an alien. But, unlike Dib, she doesn't think that Zim is a big or serious threat. In Bloaty's Pizza Hog, she replied to Dib's comment that Zim was trying to enslave all mankind with the phrase, "But he's so bad at it".

On occasion, she has bailed out her brother, but only when it conveniences her, like in Bloaty's Pizza Hog and The Most Horrible X-Mas Ever.


Though her dress style is reminiscently Gothic in appearance, she is, oddly enough, never established to be an actual Goth. This was supported by Jhonen Vasquez himself.

The most unique characteristics about Gaz are her hair and eyes. Her purple hair is cubic and fashioned into five spikes, and takes on the ominous appearance of a set of jaws. Also, her eyes are almost always closed or squinting, but when they are open her eyes are an amber color. In the Original Pilot, her eyes are blue with the exception of being amber in one scene.

In season two of the show, Gaz's head was remodeled to be more angular, like her brother's head, when facing forward towards the camera, rather than having a round shape. Her head seems to be large compared to normal human beings, but she accuses Dib (like almost every character) of having a big head. As the series goes on, she gets taller, and even has some facial changes.


Throughout the show, it is demonstrated, but never actually said, that Gaz has amazing powers. Her powers includes: the ability to fix, pilot, manipulate, and in general control anything electronic, the ability to get any place she needs, the demonic ability to levitate on pure rage alone, to create fires at will, to generate spookiness in a tangible manner, etc. She is also shown to be capable of using Irken technology and her piloting skills seem to be on par, if not greater than Zim's, as she was able to pilot one of his ships with ease. It is possible that these powers, being completely unnatural, are actually a result of her being a creation of Professor Membrane, just as it is rumored that her brother is. She, despite her demonic power, has a sort of connection to the holy, as shown in Game Slave 2, when upon getting her game back, the stormy night turns to a bright sunny day, and her hair returns to its natural shape. She also comments on how "The rightful order has been restored". In Mopiness of Doom, she comments "All is right with the world again". These are obvious references to horror movies such as "The Ring" and "The Grudge", which also contain creepy girls, as well as the plot of Game Slave 2, which somewhat parodies the aforementioned movies.

In the episode Dark Harvest, Gaz claims to have a Squeedly-Spooch. However, this may just be a retort to Dib's comment about Zim's Squeedly-Spooch.


  • The following episodes in which Gaz smiled were Parent Teacher Night (while snickering at Zim and Dib's misfortunes), The Wettening (before dropping her water balloon on Dib after Zim's watery victory against him), and Gaz, Taster of Pork (while she attempted to torture Dib with her "security" stuffed animals and mentioned that she re-programmed them to feed off of human flesh).
  • Supposedly, her personality and actions caused controversy in other source media such as Christian Parenting Today.
  • Gaz's full name is Gazlene, a play on the word gasoline
  • Her eyes are brown/hazel, although they were supposed to be light blue as they were in the Original Pilot. A coloring error led to her current brown eye color.
  • In an image on, Gaz is seen sitting playing her video game in Zim and Dib's classroom in front of Ms. Bitters, though in the television series (most notably in Gaz, Taster of Pork ), it is revealed that Gaz does not attend Skool in the same classroom as Dib and Zim.
  • During the Intro, Gaz breaks the 4th Wall by putting her hand on the screen and pushing it away.
  • On the Invader Zim website on nicktoons, Gaz was stragely removed from the character list for an unknown reason.
  • Gaz is seen in two of Snafu's webcomics: PowerPuff Girls Doujinshi, an appearance and Invader Zim: Manifest of Doom, where she is one of the main character.
