Body and Ice Parts - POC Destro

Chiller - based on the Bronze Bomber villain Chilly Pop. According to the original file cards, he was an arms dealer and the twin brother of Cool Breeze. My take is that he was a Snow Serpent, convinced by his brother, now called Doctor Frost, to undergo bizarre experiments in order to craft soldiers who are resistant to the cold. The procedure went awry and turned him into a being who can not only withstand cold, but emit blasts of ice and snow. Probably a bit too fantastic for some, but I've always liked the more outlandish elements of GI Joe.
