Thinking the surgeon Donald Blake, who has just had the power of Thor removed from him, can help him find Thor, the Grey Gargoyle goes after him. The Grey Gargoyle eventually reappears after being hauled up from the river, whereupon he turns to stone two people examining him. As Blake he defeats the Gargoyle by luring him into the Hudson River in New York City, using a projection of Thor, leaving the villain buried at the bottom. Thor is turned to stone in their first battle, but turns back to Donald Blake when he falls over and strikes the floor with his hammer. Duval, however, becomes bored and decides to try to achieve immortality by confronting the god of thunder Thor and stealing his mystical hammer, Mjolnir.

Turning his body to stone, Duval dons a mask and cape and becomes a criminal with the alias the Grey Gargoyle. Paul Pierre Duval is a French chemist who courtesy of a chemical accident gains the ability to turn any living creature to stone by touching it.
