The Sandman (William Baker, a.k.a. Flint Marko) is a 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.
In 2009, the Sandman was ranked as IGN's 72nd Greatest Comic Book Villain of All Time.Sandman is number 72 (). IGN. Retrieved 10–05–09. The character has been adapted into various other media 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), and by Jack Huston in the television series Spider-Noir (2026). An illusionary creature based on the Sandman appeared in the MCU film Spider-Man: Far from Home (2019).
Publication history 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.
Fictional character biography 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.David, Peter; Friendly Neighborhood Spider-Man Annual #1 (July 2007)
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.
His illegal activity increases in depth and scope, turning him into a violent, bitter man. Eventually he ends up in prison on Ryker's Island where he meets his father, Floyd Baker. He is friendly to his father, but does not tell him who he is. He tells Floyd his nickname, Flint, and a false surname, Marko, inspired by his former coach's taunts about not "making a mark" on the world. He uses the alias Flint Marko from that point on (he changed his name also to prevent his mother from discovering he was a criminal).DeFalco, Tom; Marvel Two-In-One #86 (April 1982) After Floyd is released from prison, Marko escapes.
Marko flees to a nuclear testing site on a beach near Savannah, Georgia where he comes into contact with sand that had been irradiated by an experimental reactor, transforming his body into sand. Impressed, he calls himself the Sandman after his new powers.
Marko clashes with Peter Parker/Spider-Man for the first time in Peter's high school. Spider-Man defeats Marko with a vacuum cleaner and hands it over to the police.The Amazing Spider-Man #4 The Sandman escapes by getting through his window after turning himself to sand, but is recaptured by the Human Torch after the Torch lures the Sandman to a building by disguising himself as Spider-Man, then activating the sprinkler system. After this Marko resurfaces as a member of the Sinister Six, led by Doctor Octopus. He battles Spider-Man inside an airtight metal box, which is activated when Spider-Man touches a card saying where the Vulture is, but the Sandman is defeated due to Spider-Man having stronger lungs than he does.The Amazing Spider-Man Annual #1
Alongside the Enforcers, he captures the Human Torch but later succumbs to Spider-Man and the Torch.The Amazing Spider-Man #18–19
After Spider-Man defeats Marko numerous times, Marko diverts his attention to other superheroes. He teams with the Wizard, Paste-Pot Pete (later known as the Trapster) and Medusa to form the Frightful Four to combat the Fantastic Four, which attacks during Reed and Sue's engagement party. The Fantastic Four, with the help of a few other superheroes, defeat the group.Fantastic Four #36 In another battle, in which he teams up with Blastaar and loses against the Four, he dons a diamond-patterned green costume designed by the Wizard.Fantastic Four #62–63 Later, he and the Hulk battle for the first time.The Incredible Hulk (vol. 2) #113 The Mandarin joins him in his next conflict against the Hulk.The Incredible Hulk (vol. 2) #114
In time the Sandman discovers—starting with his hands—that his body can transform into glass and back again. He contracts cancer and takes over a medical research center, battling the Hulk again.The Incredible Hulk (vol. 2) #138 He battles Wonder Man but is cured of his cancer by radiation.Wonder Man #1
Afterward, he allies himself with Hydro-Man to battle their mutual enemy, Spider-Man. An accident merges the two villains into a monster called the Mud-Thing. Spider-Man and the police are able to dehydrate the monstrosity.The Amazing Spider-Man #217–218 Months later, the supervillains manage to separate themselves and go their separate ways. The time he spent trapped with Hydro-Man caused Marko to question his bad life choices. The Thing, after an aborted attempt to fight Baker, urges him to straighten himself out and use his ability to do good.Marvel Two-In-One #86 The story continues when he meets with the Thing for a second time to see a sports game.The Amazing Spider-Man Annual #24 (back story) 1990, page 44
Marko boards with the Cassadas and teams with Spider-Man against the Enforcers.Marvel Team-Up #138 The Sandman then makes sporadic appearances in Spider-Man comics assisting his former enemy. His first appearance has him coming to the rescue of Spider-Man and Silver Sable, who are outnumbered and surrounded by the Sinister Syndicate. Silver Sable is impressed by the Sandman's performance and recruits him as a freelance operative.The Amazing Spider-Man #280–281 Doctor Octopus coerces him to rejoin the Sinister Six, but Marko turns against them.

Marko turns against Spider-Man and his sometimes ally the Thing and declares his allegiance to evil and his former employer, the Wizard. This change proved incompatible to what many fans had thought Sandman had become, a hero.The Amazing Spider-Man (vol. 2) #4 This outcry caused Marvel to rush out a story which retconned The Amazing Spider-Man (vol. 2) #4 in which the Wizard had kidnapped the Sandman and used his mind control machine, the Id Machine, to turn him back into a villain.Peter Parker: Spider-Man (vol. 2) #12
The machine worked too well and the Sandman went about reforming the Sinister Six to destroy both Spider-Man and Doctor Octopus, only to be double-crossed by Venom, who the Sandman recruited as the sixth member of the team. During Venom's brawl against the Sandman, Venom rips a chunk of sand from the Sandman. This missing sand destabilizes Sandman, causing him to lose his ability to maintain his human form. Before falling into the sewer (and as a nod to fans who rejected Marvel's attempt to re-villainize the character), the Sandman admitted that part of the reason for his fall from grace was the trouble he had to really cope with life on the good guys' side, and asks Spider-Man to tell his mother he was sorry he did not fulfill his promise to her, to be a force for good. The Sandman washes away and slides down a sewer, from which he mixes into Jones Beach, New YorkPeter Parker: Spider-Man (vol. 2) #22. Marvel Comics and is thought dead.
The Sandman's body and mind are scattered throughout the beach. This separation lasts too long for him, causing his mind to split into good and its opposite, evil, which when dominant created sand vortexes to ensnare beachcombers. Spider-Man arrived to confront the Sandman, ultimately using the Sandman's mental instability to free his captives and cause him to explode.Peter Parker: Spider-Man (vol. 2) #42-43
His sand wafts throughout New York and touches down into piles forming beings that personify him: the good, the bad, the gentle and the innocent. Spider-Man locates these Sandmen to convince them to unify. The Sandman's evil persona merges with his innocent and gentle personas, but the Sandman's good persona rebuffs the evil one. Because the Sandman's mind can handle his personality in separation for only a limited time, he loses his ability to retain himself, crumbling and blowing away, leaving Spider-Man to ponder the nature of his scuttled foe.Peter Parker: Spider-Man (vol. 2) #56–57
The Sandman is one of the villains recruited to recover the Identity Disc, but during its recovery seemingly he is killed in a mutiny. At the series' end, the Sandman is found alive and working with the Vulture to manipulate the other villains.Identity Disc #5
