Ignignokt and Err (known collectively as The Mooninites) are fictional characters on the Adult Swim animated television series Aqua Teen Hunger Force. Ignignokt and Err are both two dimensional space alien villains from the Moon who frequently visit Earth and cause vicious brutality for the main characters and for the planet. Ignignokt is the larger of the two who frequently appears as more calm and patient, whereas Err appears more temperamental and hyper. Both characters were created by series creators Dave Willis and Matt Maiellaro. Willis provides the voice of Ignignokt and Maiellaro provides the voice of Err.

The Mooninites were also the main protagonists in a television pilot for a potential Aqua Teen Hunger Force spin-off entitled Spacecataz, which was never picked up for a full series or aired on television, outside of clips during cold openings during the third season. The duo have appeared in various forms of media relating to the series including the 2007 series film adaption Aqua Teen Hunger Force Colon Movie Film for Theaters.

Role in Aqua Teen Hunger Force

Both of The Mooninites live in the center of the Moon, which they frequently boast about. Besides Ignignokt and Err, other Mooninites are not commonly seen with the exception of Ignignokt's uncle Cliff and a giant mooninite monster named "The Gorgotron". Despite the apparent lack of mooninites on the moon a female police officer patrols the surface of the Moon, as seen in "Jumpy George".

The Mooninites periodically visit earth in order to harass Master Shake, Meatwad, Frylock and Carl Brutananadilewski, arriving in a purple-and-blue spaceship. They particularly target Meatwad to take advantage of his childlike naivete, often encouraging Meatwad to participate in bad behavior. Frylock, who sees right through their schemes, has a very condescending view of The Mooninites and often strives to keep them away from Meatwad, himself, and their property. Master Shake is more welcoming to them than Frylock, and only slightly less gullible than Meatwad when it comes to their lies. The Mooninites seem to welcome Master Shake to a degree by giving him gifts, although they frequently try to trick Shake so they can steal from him as well. Carl is often the primary victim in The Mooninites' plans and schemes. Most encounters The Mooninites have with the main protagonists often end with them rushing to their ship as they return home, as a running gag.

Both of the Mooninites are equipped with a small laser gun that fires a small, slow-moving square bullet (despite Ignignokt's insistence on how fast it goes). Err and Ignignokt also possess the ability to lock their heads together to create the "Quad Laser", which results in them firing four laser guns at once, although this only results in them firing a much larger and much slower-moving projectile. In "The Last One", the Mooninites created an even larger weapon consisting of multiple copies of themselves formed into the shape of a giant gun which they call "The Quad Glazer" (although they argue over whether it's actually called "The Quad Glacier"). The bullet fired was even more massive and seemed to not move at all, and the sheer size of the gun caused Err to break his legs under the sheer weight of the weapon. They also have the ability to jump very high (but only on the Moon) and spin around in place flashing bright colors.

Little is known about their family lives, however, it's revealed that both Ignignokt and Err come from broken homes and neither had a father in their lives while growing up. Err went on to explain that his father was an alcoholic who abandoned him when he was three, and his mother later abandoned him at a summer camp, causing him to slip into a deep depression, and his frequent bad behavior is a desperate cry for attention. Ignignokt didn’t go into as much detail but did express some sorrow that he didn’t learn to "steal or drink the right way" from his father. In "Remooned" it is revealed Ignignokt has an uncle named Cliff, who suffers from post-traumatic stress disorder as a result of serving in the "Lunar Wars" and requires home care as a result.


The Mooninites were both created and designed by series creators Dave Willis and Matt Maiellaro and first appeared in the Aqua Teen Hunger Force season one episode "Mayhem of The Mooninites", an episode in which they were centric. The episode first aired in the United States on October 14, 2001 on Cartoon Network's late night programming block Adult Swim. Willis himself provides the voice of Ignignokt and Err is voiced by Maiellaro, whose voice is digitally altered for the role. When appearing in the series, Err is never written into the script as all of his dialog and actions are completely improvised.

The duo were originally created as ghosts from the 1982 video game E.T. the Extra-Terrestrial, an Atari video game adaption to the science fiction film of the same name. The protagonists house was to be revealed to be built on top an ancient Indian burial ground filled with old copies of the game. This premise was based on the Atari video game burial, when a surplus of over a million copies of the game, along with several other Atari games, were buried underground in New Mexico in 1983. They are both recurring characters of the series, who both have appeared more than any other characters besides the main protagonists. They are usually the main focus in the episodes where they appear, and also make several brief cameos in certain episodes as well.


The Mooninites appear as two dimensional pixelated figures with crude eyes, eyebrows, mouths, arms and legs, all composed from basic blue rectangles. Neither Ignignokt nor Err can open their mouths to speak but rather the size of the rectangle used for their mouths changes size to the rhythm of what they are saying. Ignignokt is colored with a solid shade of light green, and significantly larger than Err and has on somewhat more complex shape with several perfectly symmetrical grooves across his head. Err is light purple and square shaped with a second rectangle on his head, which fits perfectly in the groove on Ignignokt's head, which is used to form the Quad Laser and the Quad Glacier. Neither Ignignokt or Err wear clothing on a normal basis, but can be seen wearing them on occasion.

Err’s facial expression is set as angry and is never seen to change, even during an emotional monologue about his childhood in "Moonajuana", whereas Ignignokt's facial expression is predominantly set as calm and relaxed, although unlike Err his facial expression occasionally changes to express anger. Ignignokt's facial expressions never skew from calm or angry, however, his plain rectangular mouth reverts to the shape of a smile briefly during the pilot episode of Spacecataz, his mouth in the shape of a smile is never seen again outside of this one-time isolated appearance. In "Deleted Scenes" they are both hypnotized and their eyes become spinning circular spirals, a very rare alteration of their eyes. However, their facial expressions remain the same.

Spacecataz spin-off pilot

Both Ignignokt and Err served as the main protagonist for a Aqua Teen Hunger Force spin-off entitled Spacecataz. A pilot episode for the spin-off was produced, however, Adult Swim did not pick it up for a full series as executives couldn't see it going anywhere with all the characters dying towards the end of the pilot, despite the parent series having a long history of non-canon plot twists and storylines. Spacecataz was created by Willis and Maiellaro, and intended it to begin with a five episode first season. The plot revolves around both of The Mooninites and The Plutonians, another villainous duo featured in Aqua Teen Hunger Force, having an ongoing back and forth mean-spirited string of practical jokes between each other. This follows up the hostility between both groups depicted in Aqua Teen Hunger Force.

The pilot episode was never aired on television but was released on the Volume Four DVD set on December 6, 2005. The pilot was also broken down into several parts and used as cold openings throughout the third season of Aqua Teen Hunger Force; replacing short bits from Dr. Weird and Steve, which were used throughout the first two seasons.

In other media

Ignignokt and Err both make appearances together in Aqua Teen Hunger Force Colon Movie Film for Theaters, a 2007 feature film based on the series and the video game Aqua Teen Hunger Force Zombie Ninja Pro-Am.

Aside from their appearances in anything related to Aqua Teen Hunger Force or Spacecataz The Mooninites have also made a few brief cameos in other media. A hidden image of Ignignokt can be seen on a bathroom stall in the Adult Swim online flash game Five Minutes to Kill (Yourself) Family Reunion. An animated interpretation of T-Pain, who was voiced by himself, is seen wearing a necklace of Ignignokt in the Squidbillies season five episode "Asbestos I Can".
