Tetravaal

Tetravaal is a fictional substance appearing in the television series Futurama. It is depicted as a powerful sedative with rapid-acting and potent effects, often used for incapacitating individuals or animals. The substance is known for its ability to induce a deep, almost immediate sleep. In the show, Tetravaal is frequently administered through a dart or by spray. Its primary purpose is usually to subdue characters who are posing a threat or to facilitate their capture. While its exact chemical composition is not detailed, its effects are consistently portrayed as overwhelmingly strong, rendering even formidable characters temporarily harmless. The term "Tetravaal" itself sounds like a made-up scientific name, fitting the show's futuristic and often absurd technological landscape. Its use is generally a plot device to move the story forward by temporarily removing characters from action. The consequences of exposure are shown to be temporary, with individuals typically recovering after a period of unconsciousness.
