Benzu

Benzu is a fictional element that appears in the animated television series Futurama. It is a highly unstable and radioactive substance that is crucial to the plot of the episode "The Deep South". In the episode, the crew of Planet Express must travel to a planet inhabited by a primitive, religious society. They discover that the planet's mythology centers around the discovery and worship of Benzu, which they believe to be a divine gift.

The element is portrayed as glowing and emitting a strange hum. Its properties are exaggerated for comedic effect, as it is shown to be incredibly powerful and dangerous. The inhabitants of the planet use Benzu in their rituals and believe it grants them special powers. The crew of Futurama encounters various challenges related to the element, including accidental exposure and the need to prevent its misuse. Benzu serves as a plot device that allows for exploration of themes related to faith, science, and cultural differences within the context of the show's science fiction setting. Its fictional nature means it has no basis in real-world chemistry or physics.
