Greenhouse Gases

Greenhouse Gases is one of the robot muscle who turn up whenever New New York's underworld needs enforcing, a hulking presence content to loom, threaten, and follow orders from whichever boss is currently in charge. He speaks rarely and menaces efficiently, the kind of henchman built for one memorable scene rather than a starring role.

Futurama's gag economy runs on names like this: absurd, oddly specific, and delivered completely straight, which is funnier than any joke about the character himself. John DiMaggio, already doing heavy lifting elsewhere in the cast, gives him just enough gravel-voiced menace to sell the bit before the show moves on to the next one.
