The mirror universe counterpart of Vedek Bareil, a petty thief who crosses to Deep Space 9 in 2374 and becomes involved with Kira Nerys while plotting to steal an Orb.
The mirror Bareil appears in the Deep Space Nine episode Resurrection. He beams on to the station without warning, takes Kira hostage and claims to be a fugitive from the Alliance. Kira, who loved the Bareil of her own universe and saw him die, lets him stay.
He is no vedek. He has lived by stealing since childhood, and he has come with the Intendant, his lover, to carry off one of the Bajoran Orbs so that she can use it to unite her Bajor behind her.
Time with Kira, and an Orb experience in which he sees a life with her, unsettle him. In the end he stuns the Intendant rather than Kira and takes her home empty-handed, convinced that he would only disappoint the woman who believed in him.
