RPG "Bounty Hunters" guide includes Boba Fett:
No single hunter in all the known galaxy has achieved a reputation like Boba Fett ironically, less is known about him than many of his less successful competitors. Fett's trademark is the distinctive blast helmet and armor of the Mandalore warriors. There is no proof, however, that Fett was ever a member of this organization; it may be that he retains these trappings in memorial to some unknown friend or foe, or perhaps as a reminder of an era gone by.
What is certain is that no single hunter has attained as high an acquistion record as Fett. Fett is a loner. Whatever may continually drive him on, he works alone, and will work for anyone. Once engaged in a hunt, Fett uses sources of intelligence apparently available only to himself and having located his intended acquisition, Fett acts to draw an invisible net around his victim. Those who have witnessed Fett in action invariably remark on how he continually strikes when his opponent least expects it. Never content with a crude display of force, Fett attacks in the full light of day, taking his time and making his final move at a place and time of his own choosing. Often the opponent is unaware as to exactly who is hunting him, let alone from which quarter the final attack will come.
