Based on the Version of "Final Fantasy XIII Lightning Returns"
The Buster Sword (バスターソード, Basutāsōdo?) is a weapon that first appeared in Final Fantasy VII and has since appeared in several other games in the series. It is Cloud Strife's trademark weapon, and was wielded before him by Zack Fair and Angeal Hewley. The Buster Sword serves as an iconic image for Cloud and Final Fantasy VII due to its massive size and is wielded by Cloud in most of his appearances.
