Main Article: Sandman (Spider-Man 3)
After the Eddie Brock and the symbiote, Flint Marko is the main later secondary antagonist in Spider-Man 3. Years before the film's events, Marko's young daughter, Penny, became terminally ill, and he turned to bank robbing to get the money for treatment. During an escape with his partner, Dennis Carradine, Marko shot and killed Peter Parker's uncle Ben while trying to take his car, but Carradine abandoned Marko, and the latter was taken to prison.
When Marko finally broke out, he continued trying steal the money Penny needed, but the NYPD was onto him. During a chase, he accidentally fell into a large particle accelerator. Once the large mixers started to spin, there was no way out. Marko's body gradually began to disintegrate, and settled along with the millions of sand particles in the pit. He was transformed into living sand, the Sandman, and then went on a rampage, furious at what had happened to him. After a few run-ins with Spider-Man, he teamed up with Venom to destroy him. After the battle, Sandman revealed to Spider-Man what really happened the night Uncle Ben died: Marko had tried to talk Ben into giving him his car peacefully, and seeing that he was afraid, Ben told Marko to just put the gun down and go home. Marko was about to agree, but Carradine bumped into him, and Marko shot Ben by accident.
