Martok is a recurring character in Star Trek: Deep Space Nine, played by actor J. G. Hertzler.

Little backstory is given regarding the early life of Martok, except for a brief history sketched by himself in the Deep Space Nine episode "Once More Unto the Breach". It is known that he was born into a Klingon house (The House of Martok) that was not part of the aristocracy.

His family had been reputable soldiers, although not officers. Young Martok aspired to become an officer, and eventually applied. Unfortunately, his application was denied because of elitist views from the legendary Klingon warrior Kor regarding the honor and prestige of the "great houses". With a rejection on his record from such a legendary officer, Martok could no longer even serve as a common soldier. He opted to serve, regardless, and spent five years as a civilian laborer on General ShiVang's battle ship. His performance and bravery in battle caught the eye of General ShiVang, who granted him a battlefield commission as an officer. At Martok's introduction to the series, he has attained the rank of General.

Around 2371, Martok was abducted by agents of the Dominion and replaced with a shapeshifter. The exact date of this is unclear. The shapeshifter inadvertently revealed himself to Odo (who had been misled into believing that Chancellor Gowron was the shapeshifter) at a Klingon award ceremony, and was quickly killed by the Klingons attending the ceremony.

General Martok has not been a contender in any CBUB matches.
