Sandman is Flint Marko, a career criminal whose body was transformed into living sand after a scientific accident. With the ability to reshape himself into nearly any form, he became one of Spider-Man's oldest and most formidable enemies. Although often portrayed as a villain, Sandman has occasionally sought redemption and even fought alongside heroes. His complex morality and incredible powers have made him one of Marvel's most enduring and multifaceted characters.
