Worf was a Klingon male who appeared in Star Trek VI: The Undiscovered Country. Worf was the elder brother of Thok Mak and the head of the House of Mogh. He was the father of Mogh and grandfather of Mogh's sons Worf and Kurn. Growing up in the late 23rd century, Worf did not become a warrior, but instead became a defense attorney. As such his battlefield was in courts of law. Worf eventually had a son named Mogh. While Worf had never been a warriorr, he ensured that his son Mogh did become one.
