Samaritan "Sam" Bowers was a dark-skinned human male serving in Starfleet in the 24th century. A twenty year veteran, Bowers served aboard starbase Deep Space 9 and the USS Defiant in the late 2370s, then the USS Aventine in the 2380s.
Prior to his service on DS9, Bowers served on the USS Budapest as its tactical officer.
Soon after he arrived on the station, Bowers was the duty officer in the operations center of Deep Space 9.
Bowers served as tactical officer during the Defiant's three-month exploratory mission of the Gamma Quadrant in mid-2376.
By 2381, Bowers had become the executive officer of the USS Aventine under the command of Captain Ezri Dax. One of Bowers requests upon accepting the post was that business on the bridge be carried out in a much more official manner than had been the case on Deep Space 9.
Bowers and Dax's formal working relationship on the bridge quickly translated to friendship and in was not uncommon for them to use each other's first names behind the closed doors of the Aventine's ready room.
