Les justiciers du futur

From the future of Earth, 2 factions wage war: the Inheritors & the scientific Futurians. The Inheritors cause the sun to turn into a red giant, then escape the end of the world by traveling in time. To stop the Inheritors by manipulating the past, Futurians send genetic time bombs backward in time, seeding humans with superhuman potential. Callistrax sends his mind to the past, taking over a transient in 1962. 20 years later, Vanderveckan the man that the Callistrax possessed reaps the rewards of that genetic seeding when he creates his line of defense against the Inheritors: The Futurians.
