Sandman
William Baker
The rare Spider-Man villain who keeps genuinely trying to quit.
Biography
William Baker grew up as Flint Marko, a small-time crook who hid on a nuclear test beach and was fused with irradiated sand into something that can be a man, a wall or a sandstorm. He is one of the physically strongest villains in Spider-Man's gallery — punching him accomplishes nothing, and he can harden a fist into concrete or slip through a keyhole in the same fight.
What makes him interesting is that he is the only member of the Sinister Six with a conscience that keeps interrupting. Sandman has reformed repeatedly and sincerely: he worked with the Avengers, took legitimate security jobs, and joined Silver Sable's Wild Pack. Then somebody leans on him, or a job goes wrong, or the sand itself starts eroding his personality, and he is back. Marvel treats that cycle as tragedy rather than a joke, and Spider-Man 3 built its whole moral centre on it.

Comics history
Sandman debuted in Amazing Spider-Man #4 (1963), joined the Frightful Four against the Fantastic Four, and became a Sinister Six founder. Marvel gave him one of its earliest genuine redemption arcs in the 1980s, including a reserve Avengers membership and work alongside Silver Sable.
The reform was later undone — controversially — with the explanation that his sand form had been slowly eroding his humanity. Since then he has drifted between villainy and reluctant heroism, and writers keep returning to the same question: whether a man made of sand can hold a shape at all.

Trivia
- His real name is William Baker; Flint Marko was an alias he adopted as a young criminal.
- Sandman was a reserve Avenger in the 1980s, one of the most complete villain-to-hero pivots Marvel ever attempted.
- The Fantastic Four beat him early on by vacuuming him into a canister, still the most efficient counter anyone has found.
- Spider-Man 3 rewrote him as Uncle Ben's accidental killer, a change Sam Raimi has defended as necessary for the film's forgiveness theme.
- Extended time in sand form degrades his memory, the in-story reason his reformations keep collapsing.
