Dr Zoidberg left his home planet to become a rich doctor but instead he became the Planet Express staff doctor. He went to high school where he made people laugh by having barnacles on his face. When it is time for mating season on his planet, Decapod 10, he becomes angry and violent as well as producing a large fin atop his head. But once his species has mated they die. His species have their small brains in their rump. He has a cousin Zoidfarb and an Uncle, Harold Zoid, who is a silent hologram star. He has a desire to be famous wether it's in the movies or the stand up comedy circuit.
