Ed Bighead is an employee at a large corporation. He is cold, petty, evil, bossy, and has a terrible temper; in fact, the only people that he fears are his wife, Bev, and his boss, Mr. Dupette. He particularly dislikes Rocko and his friends, Heffer Wolfe and Filburt. He usually yells at anyone he sees and grumbles bitterly under his breath at any situation he finds even slightly troubling. In the musical episode, Zanzibar, O-Town's citizens are cleaning up the city, where it is revealed that he cares little about the environment and even wants "the sky to be filled with garbage too", primarily toxic waste in the Ionosphere.
