The French comic artist Moebius is the founder of Heavy Metal, called "Metal Hurlant" or "Screaming Metal" in French.
Moebius also created The Incal with Alejandro Jodorowsky.
The Fifth Element borrows some major plot points, archetypes, symbolism, scenes, etc from The Incal.
Moebius tried to sue them and lost because they paid him to work on the film without him realizing how much it would plagiarize.
