Name: Gaz Membrane
Age: 16
Appearance: Though her dress style is reminiscently Gothic in appearance, she is, oddly enough, never established to be an actual goth. 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.
Personality: 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.
History: Gaz is Dib's younger sister. She is the daughter of Professor Membrane, but, had the series continued, it would have been revealed that she and Dib are actually creations of the professor, and not his actual birth children. This may seem obvious, as Professor Membrane did not seem to have a wife.
