Donbot

Donbot leads the Robot Mafia, a trio of mobbed-up automatons running protection rackets and shady deals out of New New York. He talks softly, dresses like a wiseguy crossed with a Buick, and treats every negotiation as an offer nobody should refuse. Calm, courteous, and quietly menacing, he expects respect and gets it.

Maurice LaMarche plays him as pure Brando-via-Godfather, that wheezing rasp turning even small talk into a threat, and the joke never gets old because the show trusts the impression to do the work. Donbot's exaggerated mob-boss dignity next to his very ordinary crimes makes him one of Futurama's most efficient runs at a bit.
