The Incal (French: L'Incal) is a French graphic novel series written by Alejandro Jodorowsky and originally illustrated by Jean Giraud. The Incal, with first pages originally released as Une aventure de John Difool ("A John Difool Adventure") in Métal hurlant and published by Les Humanoïdes Associés, introduced Jodorowsky's "Jodoverse" (or "Metabarons Universe"), a fictional universe in which his science fiction comics take place. It is an epic space opera blending fantastical intergalactic voyage, science, technology, political intrigues, conspiracies, messianism, mysticism, poetry, debauchery and satire. The Incal includes and expands the concepts and artwork from the abandoned film project Dune directed by Jodorowksy and designed by Giraud from the early 1970s.
Originally published in installments between 1981 and 1988, and followed by Before the Incal (1988–1995, with Zoran Janjetov), After the Incal (2000, with Jean Giraud), and Final Incal (2008–2014, with José Ladrönn) has been described as a contender for "the best comic book" in the medium's history. From it spin-off related series Metabarons, The Technopriests, and Mégalex.
