Technically, there is only one Buster Sword but it has gone through changes once it passed from Angeal Hewey to Zack Fair and then to Cloud. The original Buster Sword is a gigantic broadsword with massive girth and personality. It has a red handle and gold detail near the guard, with a black and silver blade holding numerous markings, including the two holes near the guard. It was seen as such in FF VII the original. In FF VII Advent Children and FF VII Crisis Core, the Buster Sword we see is a bit different; the blade appears to be two pieces of metal, the piece of metal with two holes is raised a bit and has intricate designs engraved, the guard is golden colored with designs. In FF VIII the area on the sword near the two holes is also golden. In the Final Fantasy VII remake and the Compliation, the sword loses its golden guard and the area around the two holes in exchange for silver definition. The designs are gone and the red handle is now brown.
