I have a small quantity of these dudes still sealed in their bags with header cards. I think this guy was meant to be a Kamen Rider shocker character... or just a cool skeleton dude. There is another figure in this set that has Mazinger-ish face. (If you want him send me an email:)
These guys are about 4" tall and are meant to be bendy... I have played with mine a bit, but I would say bend at own risk. He's 40 years+ old. So weird and cute.
