Serge Lehman (born July 12, 1964) is the primary pseudonym of French science fiction writer Pascal Fréjean.

His stories have also appeared in Tales of the Shadowmen and he worked on the script of the film Immortel (Ad Vitam) by Enki Bilal.

[1] He gained critical attention outside the science fiction field in France with The Chimera Brigade in 2009–2010.

It describes how an elite band of superhumans, born or created during the First World War, when dubious scientific experiments took place in order to create new superweapons, have now taken control of the capital cities of Europe and try to avoid or cause total war.

The Chimera Brigade won the Grand Prix de l'Imaginaire 2011 in the newly created comics category.
