Lt. Commander Worf (Michael Dorn) often commanded the USS Defiant even though Captain Benjamin Sisko (Avery Brooks) was Star Trek: Deep Space Nine‘s Captain. After seven seasons of Star Trek: The Next Generation and appearing in the feature film Star Trek Generations, Worf joined the cast of Star Trek: Deep Space Nine in season 4. The popular Klingon was brought in to boost ratings and viewer interest in DS9, and Worf remained until the end of the series while splitting his time between DS9 and the Star Trek: The Next Generation movies.
