Head cast of Hush Com Gordon, neck dremeled out so it fits like a regular DC Classics head.
Movie Masters Joker, that comes with the rocket launcher.
Dcuc Questions coat and arms. I had to cut down the coat a bit and heavily modify the Jokers chest/back so the Questions arms would fit.
The hands, gun and holster were in my fodder box so not sure where they came from exactly. Not too hard to improvise.
