A villian in the Spiderman comics. Escaped convict William Baker hides out on a beach in an Atomic Devices Testing Center. This being the comics, the inevitable nuclear blast doesn't fry him like the poor Hiroshima-ites, but merges his body with the sand and gives him wacky powers. He can turn his entire body into sand and travel unnoticed, or make a huge fist that's as hard as cement. He's one of Spiderman's oldest foes, having first appeared in The Amazing Spider-Man #4. He joined up with Dr. Octopus, Electro, Kraven the Hunter, Mysterio, and the Vulture to form the Sinister Six.
