Pacôme Hégésippe Adélard Ladislas de Champignac is an old, castle-dwelling aristocrat, genius of a scientist. He works in many fields such as chemistry, biology, physics, but most frequently he creates chemical substances from various mushrooms found in his castle's park. These experiments may have extraordinary effects such as softening metal, allowing the body to resist water pressure, speeding or reversing the body's ageing, giving people super-strength, or even turning people black. Also a skilled engineer, he has constructed numerous incredible machines such as individual dolphin-like submarines, and other handy gadgets. He is also proven to be a paleontologist, an astronomer and an astrophysician.

Champignac is connected to several almost as eccentric scientists who frequently visit him at the castle, bringing new inventions and experiments that often bring about troublesome consequences. Due to his overall brilliance, he has several times been the victim of industrial espionage.

A wife of some time in his past has been mentioned, but no explanation of her absence was ever given. He has no children, but would eventually have a near-identical looking nephew, Aurélien de Champignac (L'horloger de la comète).
