Zack appears as a tall young man with spiky black hair. He wears the 1st class SOLDIER uniform, consisting of a black, sleeveless turtleneck, black boots, and armor.
More light hearted than his SOLDIER counterparts, Zack Fair is still as serious as a heart attack when pushed. With an open and caring heart, Zack makes friends easily and would readily lay down his life to protect them.
Zack carries with him the Buster Sword, bequeathed to him by his dying mentor Angeal, in it are the dreams and honor of his former teacher. Beyond the massive blade he carries, Zack wears the 1st class uniform version of Shinra electric's private military, SOLDIER.
