The world was at peace, somehow the Justice League had stopped the super villains. People asked for explaination, but there was none because a new threat had arrived. An intergalactic race of creatures known collectively as the Enslavers. All the superheroes of the world united and took to attack this threat. They, along with the Enslavers, never found their way back to Earth.
Years have passed and defending the world falls upon the shoulders of a new generation of heroes. Heroes that must take up the mantle of those that came before them and protect Earth from threats, old and new. They must stand for truth and justice. They must forge the a new chapter in the legacy of the Justice League!
