Even when I was a little kid I thought to myself,
'if they can make a blue & gray, camouflage, blue and DARK blue, and even GOLD for god's sake, why on earth didn't they ever make a black and gray one?'
That should have been the first one to do- besides all black like the movie.

Anyway, I used an old Iron Winch Batman (the blue and gray one.... less to repaint!!) and simply painted the blue parts black. A super easy and satisfying custom!
