Semi-known secret. "Kain" technically exists in Final Fantasy 5. Specifically Bartz character uses the same/similar design for his Dragoon outfit as Kain does in FF2 SNES version. The only true main difference is the color. Light blu🧸e kain. Dark blue Bartz. With that being said....Bartz can be renamed.....into Kain. So a꧑fter naming him Kain and unlocking Dragoon...Viola....Kain is unlocked.
