I had a Mr.Freeze head laying around for the longest time because it was supposed to be used for my animated Red Skull custom but I used a Martian Manhunter head for that one instead. I had already filed the ears off and the nose was flattened a bit, so what was I gonna do with it? That question got answered when I dug around my parts box and found a headless 'Rumble Ready' Riddler body, perfect! Deadman's collar is made of styrene and his little elfin booties are sculpted.
