Klingons were terrifying adversaries in the original series of “Star Trek,” but their culture and society were largely ignored. With “The Next Generation,” audiences were introduced to the first Klingon Starfleet officer ever: Worf, son of Mogh. Descended from a noble house but raised by humans after the tragic deaths of his parents in the Romulan attack on Khitomer, Worf became an interesting mix of his Klingon nature and human upbringing. Raised by the Rozhenko family, partially in their ancestral homeland of Russia, Worf learned many human traits and tendencies. When he was a teenager, he left to stay with Klingon relatives and undergo his rite of MajQa, which serves as a rite of passage from childhood to adulthood for Klingons. While undergoing the MajQa, the spirit of the great Klingon hero Kahless appears before him and tells him that he will do something no other Klingon has ever done before.
Worf ends up accomplishing many things that no other Klingon had done before and helps relations between the Federation and the Klingon Empire, eventually becoming the Federation Ambassador to the Klingon homeworld, Qo’noS. He also took the fall for the Klingon Empire and lost his house’s honor in order to do the right thing, then cleared his family’s name with the help of his half-human mate, K’Ehleyr, and killed the man who framed him. He helped raise a son named Alexander, married the incredible Trill science officer Jadzia Dax (Terry Farrell), and even defeated the mad Chancellor of the empire, Gowron, before passing on being Chancellor himself and giving the title to General Martok (John Garman Hertzler Jr.). He is, in no uncertain terms, a total badass.
