Stan Chupnik

Stan Chupnik was a member of the Monkey Wrench Gang in Cat's Claw.

Cat's Claw
Stan Chupnik was charged with releasing the Cat's Claw virus on President Harry Barnes and Xu Boxiong. He managed to release it but Frankie Michaelmas had killed Bernard Copeland and given the vaccine to Ayman al-Libbi. When Ken Diebold gave the President and Premier the vaccine, Chupnik was presumably given the vaccine as well.
