The Atomic Skull has gone through a few forms over the years since his debut way back in the Adventures of Superman. This is a custom made 6" version of how he looks in the JLU animated show, with some DC universe style tweaks. Atomic Skull was made from a Ghost Rider head, Superman hands, hand sculpted collar/gloves/bootplates, Bizzaro body, and Nightwing legs. His belt came from an old Duke Nukem figure and was perfect with the radiation symbol on there. The head is on a clear plastic ball joint so it looks like it's floating and the flames were made from high temp hotglue put though a low temp glue gun.
I originally used a Superman body for this figure and had him completed, but then found a Bizzaro. Atomic Skull needed that massive upper body so I transplanted everything and sculpted a new collar on. Makes a big difference I think.
