Sandman (Marvel Comics)

The Sandman (William Baker, a.k.a. Flint Marko) is a fictional character appearing in American comic books published by Marvel Comics. A shapeshifter endowed through an accident with the ability to turn himself into sand, he started out as a recurring adversary to the superhero Spider-Man, but has redeemed himself over time, eventually becoming an antihero. The Sandman has also been an enemy of the Fantastic Four and is a founding member of the supervillain teams the Sinister Six and the Frightful Four.

The character has been adapted into various other media incarnations of Spider-Man, including films, television series, and video games. In live-action, he was portrayed by Thomas Haden Church in Spider-Man 3 (2007) and the Marvel Cinematic Universe (MCU) film Spider-Man: No Way Home (2021). An illusionary creature based on the Sandman appeared in the MCU film Spider-Man: Far from Home (2019). In 2009, the Sandman was ranked as IGN's 72nd Greatest Comic Book Villain of All Time.

The Sandman first appeared in The Amazing Spider-Man #4 (Sept. 1963), created by writer Stan Lee and artist Steve Ditko as an adversary of Spider-Man. The character returned in The Amazing Spider-Man Annual #1 and The Amazing Spider-Man #18-19, and was soon depicted in other comics, such as The Incredible Hulk and The Fantastic Four.

The Sandman served as the villain of the first issue of the Spider-Man spin-off series Marvel Team-Up (March 1972), which gave him a more morally ambiguous depiction. Writer Roy Thomas later commented, "I've been pleased to see Sandman's gradual redemption, whose seeds perhaps I helped plant in that story. He just seemed to me like a character who might have that in him ..." Subsequent stories stuck with the character's original depiction, but a decade later the more sympathetic portrayal of the Sandman returned, starting with Marvel Two-in-One #86 (April 1982), in which the Sandman is given co-star billing with his nemesis the Thing. The Sandman was later an ally of Spider-Man, as well as a reserve member of the Avengers and a member of Silver Sable's "Wild Pack" team of mercenaries.

Besides being most notable as a Spider-Man supervillain, he has also been depicted as a Fantastic Four antagonist in Stan Lee and Jack Kirby comic books (mostly due to being introduced as a founding member of the original Frightful Four) along with being on the heroic side (being an Avengers reserve member) until being introduced as a tragic supervillain in the Spider-Man comics once again.

William Baker was born in Queens, New York. When he was three years old, his father abandoned him and his mother. In these early years, she took her son to Coney Island beach. He lost himself happily in sand sculptures, a craft he would use in secondary school under the encouragement of his teacher (and first crush), Miss Flint.

In preparatory school, a boy named Vic bullied Baker until he learned to fight using an opponent's motions against themselves, a technique he performed as if he "slipped through their fingers like sand". Vic and his buddies eventually befriended Baker. In high school, William played on his school's football team, using the sport to channel his anger. While playing football, he adopted the nickname "Flint", after his former teacher.

After Vic incurs a large gambling debt to a mobster, he begs Flint to fix a football game he bet on to pay off his debt. Flint does, but is kicked off the team after the coach discovers his involvement. The coach taunts Baker, telling him that he will accomplish nothing of importance in his life. Flint hits his ex-coach, resulting in his expulsion from school and the beginning of his life of crime.
