This one has been about half complete for over a year. I loved the Phase 3 Dark Trooper build-a-figure, but wanted to make him a bit more accurate to Dark Forces. The jet-black paint job was cool, but it was closer to a gun-metal/silver in the game. I did that part about a year ago. Then I ran into the figure's other problem, it's crappy SW waist articulation. Normally I wouldn't mind too much with a figure like the Dark Trooper, since it isn't really known for acrobatics, but the legs were set in a weird stance that made it difficult to stand the figure (it's really top heavy) and impossible to use a figure stand. So I decided to add better waist articulation, and spent about a year figuring out the best way to do that (I REALLY didn't want to accidentally ruin this figure, since it's nearly impossible to find these days, and really expensive when it does come up). A solution finally came when I picked up one of those Thor Destroyer figures without realizing how crappy it was (I understand the lack of torso articulation, but swivel arms? Really?). I tore it open and used the hip-ball joints which, with a little modifying, work perfectly with the Dark Trooper.
Unfortunately, I never got the official Build-a-figure plasma cannon (I got the part that came with it in a trade), so I had to use the less awesome version from the PotF Dark Trooper.
