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.
