Ghost

A spectral figure who drifts through Futurama's universe of robots and rogues, Ghost is exactly what the name promises: an apparition summoned for a single strange occasion. Voiced with Maurice LaMarche's booming theatrical flair, he appears briefly, more mood than character, floating through New New York's stranger corners.

LaMarche's voice work does the heavy lifting here, turning a thin premise into something that lands purely on delivery. Futurama often builds jokes out of throwaway apparitions like this, and having a performer capable of full-throated gravitas for a bit part is part of what makes the show's background so rewarding to notice.
