This is a character from a infamous horror indie game: FNaF 3 (Part of the FNaF series) He is the only one that can kill you in FNaF 3 while the rest are just phantoms. Here is another official link to the skin:

The outside metal can be removable by the layers of skin (can be edited in game) revealing purple guy's corpse with a endoskeleton stuck in him and white old-man hair. He also has his ribs with a metal bar and his organs. By the back you can spot a white ponytail with a rotten blue hair knot and a full-of-blood spine. If you remove the head layer of the skin you can see that I've made it look like the mask was going up, like in SFM videos with Springtrap in them. This took me about a day to detail and give it some final touches.
