Mark and Kim, who have lost the rest of the group, are left with the wounded Ling-Li. Luckily, Alexa quickly meets up with them, and they're on their way to the sea again. But when the governor and Father Loomis catch up with them, they take them straight to the mantris. In "The Betelgeuse Planet", the second cycle takes the theme of the colonisation of space further than most sci-fi comics by looking at its ecological aspect. Leilah Nakad studies the Lums, and cute animals living on the planet Betelgeuse. Seven years earlier, she led a 3,000-strong group who was to settle on Betelgeuse. But the spaceship is still flying around, lost in space. Driss and Alexa investigate.
Leo was born in Rio de Janeiro, Brazil, in 1944. In 1968, having acquired an engineering degree, he was a member of the Leftist student movement. He had to leave his country in 1971 to escape from the military dictatorship. In 1974, he was back in Brazil and decided to devote himself to drawing. When Leo discovered European graphic novels, he decided to try his luck in France and settled in Paris in 1981. He started drawing stories in Okapi magazine in 1986, and in 1989, he illustrated an album about the life of Gandhi, published by Editions Centurion. His work drew the attention of scriptwriter Rodolphe, who entrusted him with the drawings for his new series, Trent. Leo's career was established. In 1993, he launched his own series: Aldebaran, a science fiction saga of which he is also the scriptwriter.
