Lt. Worf (Michael Dorn) struggled to reconcile his Klingon heritage with his Starfleet duties throughout his time on Star Trek: The Next Generation and Star Trek: Deep Space Nine, and this conflict was set up in TNG’s very first episode. Worf was not originally meant to be one of TNG’s main characters and he spent much of the first season in the background. Before long, however, more and more stories started focusing on Worf and he eventually became one of the show’s most popular characters.
