Zack was a member of SOLDIER division. He was from the countryside, a village from Gongaga, determined to become a hero. Under the mentorship of Angeal Hewley, Zack made SOLDIER First Class, and eventually inherited his Buster Sword, becoming one the company's most dependable elites alongside Sephiroth. After a series of crises stemming from the Shinra Electric Power Company's SOLDIER program, Zack eventually passed on the Buster Sword to one of his best friends and comrades, Cloud Strife.
