The Zack Cloud Buster Sword was originally the property of Angeal Hewley, Zack Fair's mentor. Angeal used it as little as possible to prevent it from being damaged. It was created for him by his adoptive father when he first entered SOLDIER. Zack inherits the Buster Sword from Angeal after being forced to defeat him in his Angeal Penance form. Angeal spoke of the sword as a symbol of his honor. Zack seems to view it more as idealistic symbol of the honor of a SOLDIER, even though he uses it with significantly greater frequency than Angeal he admits to usually hitting with the blunt side. Zack issues the broadsword to Cloud after Zack willingly fights for his life to save both Cloud and himself. In doing so, he passes on to his friend his dreams of being a hero and his pride as a member of SOLDIER, telling Cloud that he is the proof that Zack lived.
