Bass Reeves was the first Black US Marshall west of the Mississippi. He patrolled Arkansas and the Oklahoma Territory between 1875 and 1893. He arrested around 3,000 felons and killed 14 men in self-defense. It's been pretty much confirmed that the fictional character the Lone Ranger was based on Bass Reeves, they simply made him a white man instead.
I'm convinced Marshall Reeves' first name is shorthand for "Badass".
