Arzach is a comic book collection of four wordless short stories by artist/author Jean 'Moebius' Giraud, which were originally published in the French sci-fi/fantasy comics magazine Métal Hurlant. The stories follow Arzach, a silent warrior who rides a pterodactyl-like creature through a strange, desolate landscape. The imagery and situations in Arzach are often compared to dreams or the subconscious. These stories had an enormous impact on the French comics industry, and the Arzach character is still among Moebius' most famous creations.
Moebius later revisited the character with a story called The Legend of Arzach. This later story contains dialogue, and it ties the Arzach stories into a previously unrelated Moebius story called The Detour.
