An agent of the Orion Syndicate who leans on the Tigan family's mining business in the Sappora system, and whose demands lie behind the death of Morica Bilby.
Thadial Bokar appears in Prodigal Daughter, played by John Paragon.
In 2375 Ezri Dax returns to her family home on New Sydney to help find Miles O'Brien, who has gone missing while looking for Morica Bilby, widow of the Syndicate man he once befriended. Bokar is the Syndicate's local representative, a smooth and menacing figure who has entangled the Tigans' pergium mining company in his organisation's affairs.
He had Morica placed on the company payroll as a favour to the Syndicate. O'Brien suspects Bokar of killing her, but Bokar denies it, pointing out that the Syndicate looks after its widows. The truth is that Ezri's brother Norvo murdered her after she began asking the family for more money.
