The Xentrifuge Super Soldier (left) is a highly-trained and Special-Experienced super marine. They are incredibly strategic and intelligent, strong and very fast on their feet. They are the strictest class in the Xentrifuge Empire. Never do they take off their mask, unless they are off duty and if they are in private rooms. Don't underestimate their power. The strongly hate the Phoenix Legacy and Brotherhood Prophecy.

The Mettaurian Soldier (right) is the main class. They have been around since the rise of their nation. They are less strict, they have basic intelligence, power and speed. Not as strategic in aggression, but they prove to be stable in defense. They are very socialable with other Anti-Mettaurian empires, like the Ironwing, Phoenix, Skywing, and Brotherhood.
