#103 Clayface 3 (Preston Payne)
First Appearance - Detective Comics #478
Suffering from hyperpituitarism, Payne works at S.T.A.R. Labs searching for a cure. He obtains a sample of the then-living Matt Hagen's (Clayface 2) blood, and isolates an enzyme which he introduces into his own bloodstream. Although he is briefly able to shape his own appearance, this effect is short-lived: while on a date, his flesh begins to melt, and when he touches his horrified girlfriend, she completely melts. Payne builds an exoskeleton anti-melting suit to prevent himself from touching anyone, but he learns that he needs to spread his melting contagion onto others to survive (he feels pain if he doesn't melt anyone). During this time his mental health starts to slip as he falls in love with a wax mannequin he names "Helena", thinking she is the only woman immune to his touch. After another breakdown, he thinks Helena enjoys watching men "fighting over her" when he battles Batman yet again in front of the wax doll. Although he doesn't give her up, he keeps her in Arkham Asylum, saying "we're both too polite to admit divorce, but she can't live forever."
During the events of the Mud Pack, Shondra Fuller, the fourth Clayface, begins masquerading as the hero Looker and visits Payne at Arkham. That same night, he gets into an argument with Helena and unintentionally knocks her head off. Believing he has killed her, Payne goes on a rampage until subdued in a nearby swamp by the asylum guards. Fuller, who is still using Looker's appearance and powers, rescues him and influences him to follow Basil Karlo's commands. Karlo ultimately betrays Fuller, and takes samples of hers and Payne's blood to inject into himself. He finally breaks free of Fuller's control, and is about to kill her when she admits how sorry she is for using him. The two fall in love and go on to live together, leading to Fuller becoming pregnant with their child, Cassius.
