Gloria is the sister of Zooey Deschanel and a Christian. She also attends The Skool, where she first meets most of Invader Zim cast, such as Dib (the Antichrist) and Zim (who she later, with the help of Nny, converts to a Christian).
Gloria's Mary Sue powers at first appear to be insignificant, making her avoid any harm from the Teen Ragers, but they gradually build up until it is revealed that Gloria is the Second Coming of Christ. Thus, Gloria and Dib end up having one final showdown, which Gloria wins, essentially taking over the world.
Gloria would later become the basis of a new religion in the ITS MY LIFE! universe, named Second Christians. One major Second Christian, Skepness Man Beauregarde, establishes a calendar system counting from the events of Invader Zim: Born Again Christian, named Anno Glorii.
