The Legions were created to protect Earth and other planets from a fierce foe known as the Tellnites. The Tellnites's only purpose is to take over worlds. When the Gargans visit Earth, they tell the planet about the Tellnites and the fact that their path of destruction is pointed in the direction of both Earth and Gargan, their home world. Men and women of Earth, of all races, head the call to protect Earth and their new friends, the Gargans. Little do they know that things would change in a drastic way only ten years later. Thus is born the Legion, with its creed: "No slavery in the universe."
