The Legion vs Earth - Anima Prime
Earth’s Alien Overlords! They rule earth with their super science and martial art prowess! Their from of government is a vaguely feudal setup. Each continent of earth has a General. Which then subdivide into countries being overseen by Colonel, who then commands territories through Lieutenants. Every General, and each Colonel is an alien. Though there are some human Lieutenants.
Back stabbing bastards! These are humans who have pledged themselves to the Legion, and have given parts of their bodies over to the machine for more power. Of course, this makes them easier to control as well.
Earth Freedom Front
EFF OFF! The loosely organized rebellion against the tyranny of The Legion!
