Atom Smasher's base is a 'Fighting American' figure chosen for his size and scale in comapsrison to the other "5-"6 figures since Atom Smasher is listed as being well over 8 feet tall and being capable of even going to 15 feet. This is the largest custom I have done to date.
The head was modified was Magic Sculp to hide Fighting American's features. The tricky part on this custom was his boots if you'll notice the ridges on the inner part of his boots. Those were made by pumping out Magic Sculp through a clay gun (lifesaver!) and then wrapped around the boot and cut to size. The clay gun was also used for his wristbands and neck piece. His belt is a shaped and sanded piece of plastic. I also had to fill in all the fine line indentations from the original base figure..ugh.
