All My Circuits

Futurama is an American animated science fiction sitcom created by Matt Groening and developed by Groening and David X. Cohen for the Fox Broadcasting Company. The series follows the adventures of a late-20th-century New York City pizza delivery boy, Philip J. Fry, who, after being unwittingly cryogenically frozen for one thousand years, finds employment at Planet Express, an interplanetary delivery company in the retro-futuristic 31st century.

Futurama has eight main cast members and many other incidental characters. For an overview of the show's main characters, see the list of Futurama characters.

Lieutenant Kif Kroker (voiced by Maurice LaMarche) is the long-suffering assistant to Captain Zapp Brannigan, and Fourth Lieutenant on the Democratic Order of Planets (DOOP) starship Nimbus. Kif is a short and thin green skinned alien crew member. His frustration with Brannigan's arrogance and general incompetence in Season 1 leads him to be a disaffected, indifferent, sardonic lackey, although his personality differs greatly in later seasons. Zapp thinks Kif to be his best friend and loyal confidant, whereas Kif sees Brannigan as an incompetent jerk, going so far as to call him a jackass in "Love's Labours Lost in Space". Despite this, Kif seemingly has some loyalty to Brannigan, even continuing to associate with him after Brannigan caused him to be court-martialed along with him in "Brannigan, Begin Again". Kif is in a relationship with Amy Wong.

Lord Nibbler (voiced by Frank Welker) masquerades as an innocent, cute and unintelligent pet during most of the series. In reality, he is a highly intelligent Nibblonian and capable of communication, but tries to avoid suspicion while he protects the Earth in general and Fry in particular from the Brainspawn. As with all Nibblonians, Nibbler's feces consist of dark matter, which can be used as starship fuel. It is an extremely dense material, "each pound of which weighs over ten thousand pounds", according to Professor Farnsworth in the season 1 episode, "Love's Labours Lost in Space". After he accidentally reveals to the Planet Express crew that he can speak in Bender's Big Score, he forgets to wipe their memory of his intelligence, which it turns out does not affect them much, and from then on he speaks freely to the crew.
