The Worlds of Aldebaran (French: Les Mondes d'Aldébaran) is a French science-fiction comic series written and illustrated by Léo and published by Dargaud in French and Cinebook in English. The Aldebaran saga is divided into 3 cycles: Aldebaran and its sequels Betelgeuse and Antares. Each cycle is composed of some five albums, and each corresponds to a different planet. Although it is possible to read the cycles separately, they are chronological to form a coherent whole. Each cycle (and thus planet) introduces new secondary characters, although the central heroes of the story remain constant.
