Worf is the son of Mogh, and a Klingon raised by humans after his parents were both killed by a surprise Romulan attack at Khitomer. He is also the first Klingon officer in Starfleet, though most other Klingons shunned his choice of duty. Worf considers himself a Klingon at heart despite being raised by humans, and studied the ways of his people. His mannerisms, personality and great sense of honor would classify him more Klingon than human.
