Filler Bunny, as suggested by his name, was originally created to fill up space. He has a very rushed appearance and appears poorly drawn. Eventually, Filler Bunny received its own comic, which Jhonen Vasquez claimed he only drew up hours before the deadline.

This was also the case in the second Filler Bunny comic released. However, in his third Filler Bunny comic, which was released in 2005, he changed this method and spent months working on it, which was a hit with some fans, but a sort of disappointment to others, who believed this ruined the theme of Filler Bunny being rushed and perhaps poorly drawn.

Filler Bunny made a cameo appearance in Invader Zim as a dashboard accessory on the bus in Walk of Doom, and another one at the beginning of Dark Harvest , in a jar filled with liquid. A "Skool" employee sets him down on a counter near a open window. A dodgeball comes through the window and smashes his jar, and he is never seen in Invader Zim again.

TriviaEdit

• Both GIR and Filler Bunny are seen riding pigs.
• It is heavily hinted in the comics that Filler Bunny has some mental issues or deals with depression, as his main goal in life is to end his own.
