Edward "Ed" Bighead is a fictional character and the main antagonist from the Nickelodeon animated series Rocko's Modern Life and the comic book series of the same name. He is an anthropomorphic cane toad that lives next door to the main protagonist of the show, Rocko Rama, whom he vehemently dislikes for no reason, except for spite. Bighead is an employee at Conglom-O and wants to prove that he is the best neighbor on the block. Occasionally, he also likes causing misery to Rocko, Spunky (Rocko's pet bull terrier), and Rocko's best friends Heffer Wolfe and Filburt Shellbach, sometimes even going as far as actively trying to kill them.
