In 2370, after the exposure of the Cardassians involvement in the Bajoran Alliance for Global Unity, Pa'Dar was put in charge of the investigation to investigate and prosecute the high ranking officers involved. Dukat was one of those suspected.
Later that year, it was learned that his son, Rugal, had survived and was being raised by a Bajorian family, as he was thought to be an orphan. Dukat planned to use this evidence in an attempt to politically disgrace Pa'Dar. Dukat's plan was foiled when Elim Garak and Julian Bashir found out that Rugal was deliberately left behind by Dukat. Sisko than returned the boy to his father. (DS9: "Cardassians")
- Pa'Dar was played by Robert Mandan.
