Pazuzu

Pazuzu is a gargoyle-like demon who Professor Farnsworth owned and put through. Pazuzu escaped and due to Farnsworth's senility he could not be found. However it is later revealed that he was hiding on a wing of the and when Farnsworth was drowning in the Fountain of Aging, Pazuzu saved him and in reward Farnsworth granted him freedom. Pazuzu moved to Paris and had a son to whom he told his story of freedom.

He is apparently bound to grant the Professor three wishes, though the reason is unknown. The wishes do not seem to be supernatural in nature, as he has only been shown to rescue the Professor from two desperate situations.

Trivia

 * He is named after, who was the king of the demons of the wind in Assyrian and Babylonian mythology.
 * The Mesopotamian Pazuzu was also the basis for the demon prince in Dungeons & Dragons, who can be found within the . There are frequent references made to Dungeons & Dragons throughout Futurama. The Dungeons & Dragons version of the character can grant wishes when his name is said three times, possibly the source of Farnsworth's three wishes.
 * While Pazuzu is not overtly evil, he exhibits demonic features (such as glowing eyes), and at times the Professor refers to him as "Fiend" (which is also a term in Dungeons & Dragons referring to demons and devils aligned with evil, another D&D reference), however him being an actual demon remains undetermined.
 * He can say "Bonne nuit" ("Good night"), meaning he may be able to speak the French language, even though it is considered a dead in the 31st Century.
 * In The Beast with a Billion Backs, Pazuzu said the Professor still had one wish left (the first was possibly to escape the Fountain of Aging, and the second to escape from prison), which means it's possible that he may come back.
 * Though not named in the movie, Pazuzu was the name of the demon who possessed Linda Blair's character Regan MacNeil in the 1973 film . A flashback early in the film shows Pazuzu as half-demon and half-, similar to how he appeared in Futurama.
 * The cathedral at the end is the Notre Dame de Paris, and Pazuzu's final words is a reference to one of the gargoyles from the Disney movie .
 * Pazuzu was also the name of the demon of the Eiffel Tower in "Le Démon de la tour Eiffel", an issue of 's French graphic novel series .
 * Adèle Blanc-Sec, the heroine of the novel and the character who is haunted by Pazuzu in the midst of Paris, is a recurring character in Tardi's writings. Although the timeline of his works' settings jumps over several decades, with Adele's first adventures taking place around 1910 in Paris and her next appearance during the interwar period long after, she remains roughly a consistent age and, despite her own inclination to do so, does not participate in WWI. Tardi explains this later in an interview saying that Adèle had been cryogenically frozen.
 * The hovering Eiffel Tower at the end of "Teenage Mutant Leela's Hurdles" and Pazuzu's relocation to Paris are likely references to Tardi's Novel.
