Dashiell "Dash" Bad Horse (Lakota: Sunkawakan Sica), a.k.a. Dashiell Bradford, is a full-blooded Oglala Lakota who left the Prairie Rose Indian Reservation at the age of thirteen before returning with a vengeance in 2007. Although happy to have left the reservation, he resents his mother for sending him away, believing she chose activist causes over the welfare of her only child. The fifteen years in between were spent on contact sports, learning Jeet Kune Do, and serving with the U.S. military in the Kosovo War before becoming an FBI agent. A fiery brawler that taps into his anger during fights, he has defeated hordes of enemies at a time, but is not the sort of man to kill in cold blood. He shaves his head and wears several earrings. His cold, withdrawn, anti-social demeanor contrasts with his propensity to start fights with little provocation or reason. Described by FBI Special Agent Baylis Nitz as a "borderline sociopath," his motivation for returning to the reservation is at first unknown, but later revealed to be legal troubles which Nitz has promised to erase if Dashiell successfully completes his mission.
