Paul Pierre Duval is a French Chemist who, after a freak chemical accident, discovers he can turn anything to stone and immediately surrenders! No, but after a series of heists, he decides to try and gain immortality by stealing Mjolnir, only to be thwarted by Thor's alter ego, Donald Blake. Pfft, French super villains... if he wants to be a Thor 2 villain he better step it up.
