The Sky Armor is an enemy from Crisis Core -Final Fantasy VII-. It is similar in appearance to the Heli Gunner. As with all flying machine enemies, it has a very high Vitality stat, so using magic-elemental attacks, particularly Lightning-elemental attacks, is the way to go. They have the standard Spin Attack, but now come with the 88mm L42 Cannon, which deals heavy damage as well as knocking Zack to the ground. This attack can be dodged with the right timing however, so it should not pose too much of a problem.
