Clayface III
Hooray-face for Clayface!
Everyone knows and loves Clayface, but there’s been one incarnation that no one gives any love to, which is sad, because he’s pretty great. Preston Payne suffers from a rare disease and spends most of his time working at S.T.A.R. Labs trying to find a cure. One of his attempts is to use (the second Clayface) Matt Hagan’s blood to cure himself.
At first, he gains the shapeshifting abilities he so desired, but then, something goes horribly wrong. He begins to melt. Like, horrifically. Also, when he touches others, they melt like they’re looking into the Ark of the Covenant. He builds himself a suit to hold himself together, but he soon learns that if he doesn’t consistently melt people, he experiences horrible pain.
Payne is on this list entirely because of his role in Alan Moore’s best Batman story, in which Preston falls deeply in love with a Mannequin. It’s sad and weird and creepy as all hell, and you NEED to read it.
