Pazuzu

Pazuzu is a gargoyle who Professor Farnsworth owned and put through college. 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 Planet Express ship 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 who he told his story of freedom to.

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.

 * 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.

 * 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.

Tardi explains this later in an interview saying that Adèle had been cryogenically frozen.
