Wild 9

Wex Major is a teenager from Earth whose parents were kidnapped by aliens. Traveling through space, Wex comes into contact with a powerful weapon system known as The Rig. Apparently the young boy is the only one who can harness the power of The Rig, and he is proclaimed The Great Champion, a legendary leader who can rid the oppressed people of the Andromeda Galaxy from the tyranny of the evil gigantic monster named Karn. Wex recruits other teenage mutants and becomes the leader of Wild 9, an organization that aims to overthrow Karn and liberate the galaxy.
