He has been mainly involved in the science fiction and fantasy genre, often with a decidedly erotic slant. His fantasy stories range from sword and sorcery to the 1001 Arabian Nights type. He also raises the issue of conflict between peoples, such as in science fiction stories where the inhabitants of soon-to-be colonised planets are massacred so that humans from Earth can move in.
One of his most recurring characters is Lorna, a Barbarella-like space adventurer who travels the galaxy accompanied by two droids, the R2D2-like ADL and the C3PO-like Arnold. Arnold's main function is to satisfy the ever-passionate Lorna whenever there are no human males, females or suitably endowed aliens available. Also, appropriately enough, Lorna's principal enemy, the crime lord Mouse, bears some resemblance to Jabba the Hutt.
Less adult-oriented, and suitable for younger readers, was Mot, the adventures of a boy called Leo who finds himself plagued by a large, friendly but cumbersome and destructive monster. This was turned into a cartoon series and broadcast on France's Canal Plus.
Azpiri's other productions include Chang, telling the adventures of a martial artist and detective.
Both Lorna and Mot were featured in video games, Lorna by Topo Soft and Mot by Opera Soft.
