Life appears straightforward for Koichi, a young student, until he discovers that he is the reincarnation of an alien protector who has suddenly assumed the mantle of responsibility as the "defender of the Earth". Koichi/Babel joins forces with a trio of super-powered alien companions to battle the dark forces of an evil cult leader. The war to save humanity takes Babel from the deserts of southern Asia to the Upper East Side of Manhattan and ultimately to a final showdown with "the master" in a hidden base nestled in the Swiss Alps. The action is fast-paced and deadly. The fate of the world rests on the ability of this courageous youth to tame his latent psychic power and use it to defeat the enemies of mankind.
