The Bounty Hunter is a Career from the Edge of the Empire Core Rulebook.
The name says it all: this is a hunter who seeks to collect bounties for his work. Bounty Hunters tend to be feared, reviled, looked down upon – and in great demand across the galaxy. They are expert trackers, brutal combatants, and effective investigators. They tend to prefer skulduggery, stealth, and traps over frontal assaults, but the most respected Bounty Hunters will do whatever it takes to catch their quarries and collect their fees.
Jango and Boba Fett, Cad Bane, and IG-88 are examples of Bounty Hunters in Star Wars.
