Ferengi officer set on revenge for the death of his son who was killed after an encounter with the U.S.S. Stargazer, commanded by Jean-Luc Picard, in 2355. After failing in his attempt to destroy Picard, Bok was stipped of his title and sent to Rog Prison. He later resurfaced in 2370, attempting to kill Picard's "son" Jason Vigo. The young man was not Picard's son, but his DNA had been resequenced to imply that he was. Bok was, once again, released to Ferengi authorities after this other attempt at revenge failed.
