Gaz is first mentioned in chapter 6 of TEEN FORTRESS 2, as Demonman's girlfriend. This is a jab by MarissaTheWriter at Skepkitty, who is a fan of Invader Zim and whose blog, The Half-World, primarily reviewed Invader Zim fanfic before ITS MY LIFE! and TEEN FORTRESS 2.

Other than that, she is only given cameo appearances. After Demonman's eye is shot, Gaz gives him a goth emo eyepatch. She is also a brief bystander when Principal Business Man is taken away to become a member of the extended TEEN FORTRESS 2.

Invader Zim: Born Again ChristianEdit

In Born Again Christian, Gaz's first appearance is looking at Dib when he returns home. She finds a 666 mark on his body; an early hint that he is the Antichrist. Gaz later appears to direct Gloria Deschanel to Johnny the Homicidal Maniac, while at the same time mentioning a change in Dib's personality.

She is killed by Dib, as he has repeatedly failed to kill someone in order to join the Teen Ragers, and after his last plan is foiled, he shoots her instead. This causes outrage from Professor Membrane, whom Dib shoots as well.

The Chronicles of DA SUsEdit

Gaz only receives a cameo appearance in The Chronicles of DA SUs, as she is playing a video game at the cafeteria when Kitteh and Mary-Sue take their seats.


In THE MARRISSA GAMES, it is implied that Gaz studies at Half-Life College, and continues to date Demonman there.

"Gaslenna Membrain" is briefly mentioned in Dick Stiller and Roxa Lavigne's Time Travellegiance, as the subject of Lately Pirate's gay affection.
