Aldebaran

In the early 2000s, Leo launched the science-fiction saga Aldebaran with publisher Epsilon, a five-issue series that marked the beginning of his expansive "Les Mondes d'Aldebaran" universe. Blending Leo's signature lush, detailed artwork with a contemplative narrative co-written by Mark O. Fischer and Johanna Stehr, the story follows human colonists on a distant planet as they confront an enigmatic alien ecosystem and their own fragile society. This series is essential for fans of thoughtful, character-driven space exploration, establishing the tone and visual identity that would define Leo's acclaimed, long-running cosmic epic.
