Peacock

Peacock is one of the many robots crowding the background of Futurama's future New New York, a minor bureaucratic or working presence rather than a marquee name. He turns up doing whatever the plot needs of him, brisk and functional, part of the vast mechanical citizenry that makes the show's world feel populated rather than staged.

Futurama's genius is treating throwaway robots as fully imagined citizens, and Maurice LaMarche's voice work gives even a glancing character like Peacock a specific, funny cadence rather than generic robot noise. LaMarche's range across the show's cast means each small role lands with its own personality, which is exactly what makes the world feel dense and alive.
