The first Klingon in Starfleet, raised by humans, later strategic operations officer on DS9.
Worf is a Klingon officer raised by humans who serves as security chief of the Enterprise-D and later as a key figure on Deep Space Nine. Played by Michael Dorn, he appears in more Star Trek episodes than any other character and carries a strong sense of honor and duty.
His story is shaped by the tension between his Klingon heritage and his Starfleet service. He loses his place in the Klingon Empire in an act of loyalty, rebuilds his honor over years, and raises his son Alexander. On Deep Space Nine he serves as a strategic officer, marries Jadzia Dax and forms a lasting friendship with Martok. He returns in Star Trek: Picard, where he works alongside the fleet's old allies.
Worf endures as a symbol of courage, loyalty and the search for belonging across cultures.
