If Captain Benjamin Sisko (Avery Brooks) became Admiral Sisko after Star Trek: Deep Space Nine ended, he would have changed Star Trek for the better. Brooks made history by portraying Sisko, the first African-American lead of a Star Trek series, for all 7 seasons of DS9. Along with commanding Deep Space Nine, Sisko was the Emissary of the Prophets of Bajor. As Emissary, Sisko was a powerful religious figure who was destined to become a demigod rather than continue his successful Starfleet career.
Sisko began Star Trek: Deep Space Nine as the Commander of the space station. But Ben was also a widower mourning the loss of his wife, Jennifer (Felecia M. Bell), and raising their young son, Jake (Cirroc Lofton), as a single parent. Sisko was promoted to Captain in DS9 season 3, just as the Dominion from the Gamma Quadrant was beginning to threaten the United Federation of Planets. Along with playing a pivotal role in the Dominion War, which the Federation and its allies ultimately won, Captain Sisko also continually dealt with his nemeses, Kai Winn Adami (Louise Fletcher), his rival as Bajor's religious leader, and Gul Dukat (Marc Alaimo), Sisko's main Cardassian foe. At the end of DS9, Sisko fulfilled his destiny to save Bajor, and he chose to become one with the Prophets as a non-linear being, leaving his loved ones, and Starfleet, behind.
