An articulated AT-DP trooper. He's seen zipping around on Lothal in the first episode of Rebels.
Used the AT-AT figure for the basis. The chest armor came from the Imperial gunner, and the shoulder armor from a clone trooper. The helmet is from the AT-DP figure but I dremeled a hole into it so it would fit onto the neck post. The head is a spare Dutch Vander I had lying around.
For the armor, I chose a darker grey. I've seen pictures of other customs of this figure and some chose a blue-grey for the armor. I watched the episode several times and found a good picture in SW Stormtrooper: Beyond the Armor that showed a darker, almost black. Also did a basic black wash to make him look dirty.
