Brunt was a Commissioner of the Ferengi Commerce Authority in the 2370s, until 2376. He later became a bounty hunter, working with Gaila and Pel, before joining the prestigious Ferengi Entrepreneurs' Club.
In 2371, Brunt met Quark for the first time, during an investigation into his mother Ishka's business deals. He developed a deep dislike for the bartender, feeling he and his family were dangerous to the Ferengi race. (DS9 episode: "Family Business")
In 2372, Brunt would return to DS9 to order Quark to end a strike in his bar. In the same year, Brunt managed to revoke Quark's business license for breaching a contract with him. This led to Quark's expulsion from the Ferengi business world, but thanks to the kindness of DS9's populace Quark was able to keep the bar open. (DS9 episodes: "Bar Association", "Body Parts")
In 2373, Brunt attempted to take over as Grand Nagus by showing that Zek had lost his business skills; however, his plan was foiled when Quark reunited Zek with Ishka. Afterward, Brunt was fired from the FCA and attempted to get back in the good graces of Zek by helping rescue Ishka from the Dominion. (DS9 episodes: "Ferengi Love Songs", "The Magnificent Ferengi")
Bu 2374, Brunt had managed to maneuver his way into the position of Grand Nagus by deposing Zek, but Zek was soon able to regain his standing with the FCA and Brunt once again was a liquidator. (DS9 episode: "Profit and Lace")
In 2376, Brunt gained a seat on the new Ferengi Congress of Economic Advisors instituted by former Grand Nagus Zek. Brunt unsuccessfully attempted to have Grand Nagus Rom removed from office with a scheme devised by Brunt and a Ferengi businessman named Dav, Rom's former father-in-law. After the failure, Brunt not only was expelled from the Congress, he also got stripped of his business license. Only after Quark's cousin Gaila offered to make Brunt a business partner was he able to get back on his feet. (DS9 - Worlds of Deep Space Nine novel: Ferenginar: Satisfaction is Not Guaranteed)
In 2377, Brunt, now Gaila's partner, assisted him in several business transactions, the first of which was to sell weapons to three separate factions on Kalanis Major. Afterward, they would travel to Risa for a vacation where Brunt would gain information about the Urwyzden system. Following up on this lead, the partners took the Golden Handshake to Urwyzden and over the next several months managed to start a war among the Urwyzden during which Brunt and Gaila managed to sell weapons to all three planets. After months of dealing weapons Gaila began to believe Brunt and Pel, another crewmember, were plotting against him and had his personal guards attack Brunt and Pel. After escaping the Golden Handshake, Brunt rescued Pel from the planet's surface and fled the system. Several weeks later, Brunt returned and informed the governments of all three worlds that he and Gaila were behind the war. In order to make up for his part, Brunt was told he had to capture Gaila which he did. Following his capture of Gaila, Brunt became a bounty hunter. (DS9 novella: Reservoir Ferengi)
