This is a custom that me and my son have been involved in for about 3 months.I had the materials and he supplied the toy.A lot of work went in this custom and I wanted to build one that nobody else had(one of kind).This is my second custom and I hope to make more.Anyway the the head was grinded smooth except for the eyes and eye brows,and everything from the spike on the head to the mouth was made by me.He still retains most of his original movement except for the head,he can look side to side,but no longer up and down.The only complant is how heavy he is,it is hard for him to stand on his own,so next I will be building a stand.Hope you guys like him!
