In The Grip of The GARGOYLE!
According to Travis Starnes' Website, it states," With a touch that can turn any man into stone, the Grey Gargoyle battles the Falcon and Captain America. He makes a strategic retreat with hopes of creating an army of living statues, and culminating his plan by stealing Element X."
