Sidewinder was the founder and original leader of Marvel's Serpent Society, a group of snake themed villains. I used a Marvel Legends Giant Man as the base body, with Dr. Strange forearms, and Morbius hands. The arms were sanded down and almost completely sculpted over with scales. I also sculpted new details on the body. The head is an unmasked Iron Skull head that is partially re-sculpted. The cape comes from Grim Reaper, and the collar is just thin plastic with fishing line glued on for the lines.
