The Grey Gargoyle is a Marvel Comics supervillain who first appeared in Journey into Mystery #107, published in August 1964. Created by writer Stan Lee and artist Jack Kirby, the Grey Gargoyle is the alter ego of Paul Pierre Duval, a French chemist.

Paul Duval was working on an experimental potion when an accident occurred, granting him the ability to turn any part of his body into a stone-like substance upon touch. As the Grey Gargoyle, he has the power to temporarily petrify living beings or objects that he touches, rendering them immobile.

Initially, the Grey Gargoyle started his criminal career by committing thefts and using his powers to immobilize his enemies. He clashed with Thor numerous times, becoming one of the recurring foes of the God of Thunder.

Over the years, the Grey Gargoyle has appeared in various Marvel Comics titles, often as a formidable opponent for heroes such as Thor, Iron Man, and the Avengers. While he possesses an unusual power, the Grey Gargoyle is often depicted as a relatively low-level villain compared to Marvel’s more prominent threats.

The character has made appearances in animated adaptations, such as animated TV shows like “The Avengers: Earth’s Mightiest Heroes” and “Iron Man: Armored Adventures.” The Grey Gargoyle’s powers and abilities, combined with his unique appearance, make him a distinctive adversary within the Marvel Universe.
