Olivier Vatine made his name with this 1989 sci-fi graphic novel series which was an inspiration for James Cameron's Avatar. Out of print.
From the publisher:
This beautifully illustrated volume continues the science-fantasy adventures of Nao. In order to reclaim his inheritance and save his adopted planet, Aquablue, from total disaster, he must return to his birthplace...Earth. While Nao attempts to keep Aquablue from becoming a convenient energy source for Earth's power-hungry corporations, his bride, Mi-nuee, stows away on a ship also bound for Earth and falls into the hands of the enemy.
