History

  Nathaniel Walls was an overweight member of the street gang called the Sixties in Detroit. During the Gulf War, he served in the U.S. Marine Corps together with Tommy Monaghan. The two of them first met when they killed an SAS patrol by mistake. After their service, they both became killers for hire - Tommy as "Hitman" and Nathaniel calling himself "Natt the Hatt" (after the big hat he wore night and day). Natt started working together with Hitman in Gotham City and became part of Tommy's "Cauldron Crew", the mercenaries frequenting Noonan's bar in Gotham's Cauldron area. Tommy and Natt were best friends, always watching each other's backs and working side by side until the bitter end. In their last mission, the two were brutally killed in a shoot-out with government agents.
