There was a variation for the single boxed Black Series 6" Clone Commander Bly figure which had a brown stripe go all the way down in the middle of the helmet. Pictured below on the left is the promotional image sent out by Hasbro but a limited number of those figures have made it out to retail. The later and more commonly found Commander Bly Black Series figure can be seen on the right.
