Using the ARF Trooper figure as a base, I compiled the upper neck-brace from a red Clone Commander figure, cutting off the left shoulder pad, and replacing it with the pad used on one of the original release ARC trooper blue figures. The skirt/torso cape came from the same red Clone Commander the neck brace came from. Then, I switched out the arms and lower legs from a live-action based trooper. And, finally, I used the alternate helmet from the clonewars Obi-Wan figure for the helmet.
For added articulation, I made the wrists ball joints.
The strap on his rifle was replaced using a GI: JOE general purpose strap piece.
The figure was painted using Model Master Acrylics.
