The mirror universe counterpart of the liquidator Brunt, a mild and decent Ferengi who works beside Ezri Tigan and is murdered by Intendant Kira in 2375.
The mirror Brunt appears in the Deep Space Nine episode The Emperor's New Cloak. Where the Brunt of the prime universe is Quark's spiteful persecutor, this one is courteous and generous, to the astonishment of Quark and Rom when they meet him.
He works with the mercenary Ezri Tigan and is plainly in love with her, though he knows she does not return the feeling. He treats the two visitors kindly while they are held on Terok Nor.
Intendant Kira comes to doubt his loyalty and kills him without warning. His death is what finally turns Ezri against the Alliance, and so it leads directly to the capture of Regent Worf.
