Flint Marko / William Baker - the Sandman

William Baker, a troubled individual, adopted the alias Flint Marko and turned to a life of crime after a rough upbringing. He gained sand-based powers after being caught in a nuclear test, becoming the Sandman. Initially a formidable villain and founding member of the Sinister Six, a traumatic event led him to briefly reform and join superhero teams like the Outlaws and Wild Pack. However, he was later corrupted by the Wizard and reverted to villainy, though a spark of good occasionally resurfaces.
