Cosplayer and cosplay photographer, Ty_asselin on Instagram (HalfLightPhotography), recently completed a Fox McCloud cosplay at the C4 Central Canada Comic Con in October 2017. His costume included a game-accurate version of Krystal's staff made from cut, shaped, and carved foam. I am particularly impressed with the care with which he matched the pattern on the shaft. There aren't really any photos of him in costume with the staff that I have seen, but he said he's going to try and do some more photos with the Fox McCloud costume soon. Maybe we'll see more. In the meantime, you can look at some work-in-progress shots and a few photos of the completed staff.
