Joson Wabak was a male Bajoran who held the rank of lieutenant, junior grade in Starfleet and was assigned to the USS Defiant. Joson's brother Joson Jaras had been a member of the Bajoran Resistance during the Cardassian Occupation of Bajor.
In 2373, Joson took command of the Defiant when Benjamin Sisko and the senior staff were helping the Tiffnaki to repel a Cardassian and Drek'la invasion. The Defiant was later attacked and Joson piloted the Defiant down into the Tiffnaki ocean. (DS9 - Rebels novel: The Conquered)
