Sir, I protest! I am not a merry man!
~ Worf

Worf, Son of Mogh is a heroic character from the Star Trek franchise. He was also the first Klingon in Starfleet, to be followed by B'Elanna Torres and her daughter, Miral Paris.


Worf was born on the Klingon homeworld of Qo'noS on the Earth date Dec. 9, 2340. He was the son of Mogh and his wife Kaasin, and was named after Mogh's father. He was the elder brother of Kurn. At a young age Worf accompanied his parents to the Khitomer as Mogh attempted to track down a traitor who was working with the Romulans. Mogh was unable to uncover Ja'rod's treason before the Romulans attacked, killing over 4,000 Klingons - including both of Worf's parents.

The Starfleet vessel Interpid responded to the disaster. Worf was discovered by a Chief named Sergey Rozhenko. Worf had some injuries that resulted in some memory loss. Informed that Worf had no surviving relatives, Sergey and his wife Helena took Worf into their family. Mogh's friend Lorgh assisted in making sure the adoption was approved by the Klingon government. In order to ensure the survival of the House of Mogh Lorgh in turn raised Kurn as his own son.

Worf tragically learned the need to be disciplined in his reaction with humans when he accidentally head butted another young human named Mikel during a soccer match. Mikel broke his neck in the process. Even though it was an accident Worf felt a great deal of guilt over causing that death, and worked to make sure another accident like that never happened again. This caused him to distance himself from others and carry himself with a serious demeanor.

When Worf came of age he and his human brother Nikolai entered Starfleet Academy. Nikolai found he didn't like life at the academy and left after about a year. Worf stayed with it and graduated in 2361.

In 2364 Worf was assigned to the Enterprise-D under Captain Jean-Luc Picard. Except for when left Starfleet to fight in the Klingon civil war he would remain on the Enterprise until the ship was destroyed in 2371.

After the destruction of the Enterprise Worf was called to assist Captain Benjamin Sisko on Deep Space Nine.

During his time on Deep Space Nine Worf became close friends with and eventually married the joined Trill Jadzia Dax. In 2374 Worf chose to save Jadzia's life instead of going to a rezendevous with a Cardassian defector, this seriously damaged Worf's career and Benjamin Sisko told him he would probably never be given his own command after this.

He was assigned to Deep Space Nine until 2375, when he was named Ambassador to the Klingon Empire.

Novel Continuity

Worf would later return to Starfleet, leaving his son Alexander as the Federation's ambassador to Qo'noS. Picard had Worf promoted to the rank of Commander and assigned as his first officer on the Enterprise-E following the promotion of William Riker to Captain and subsequent departure to command the USS Titan, and the death of Commander Data. It took a great deal of effort on Picard's part to convince Starfleet to let him have Worf as his first officer.

After the death of Data his cat Spot came to live with Worf. Worf and Spot did not get along at first but soon Worf came to see the Terran feline as a proud warrior who saw what she wanted and took it. When Data's matrix was revived in a new body in 2384 Worf kept Spot as Data had decided not to return to Starfleet at that time.

Online Continuity

In the Star Trek: Online continuity Worf married Grilka in 2386, and the couple had a son they named K'Dan. In 2387 Worf became a General in the Klingon Defense Force, and attempted to stop Nero from taking revenge on Vulcan and the Federation for the destruction of Romulus.


  • Worf was portrayed by Michael Dorn in The Next Generation (TV series and films), Deep Space Nine, and most recently, Star Trek Online mmo game. Dorn won the part by showing up to his audition acting like what a Klingon did. That along with Dorn's stage training and lack of what the producers called "street accent" led to them offering the part to Dorn.
  • Worf was originally intended to be a reoccurring character during the first few episodes of the series. Seeing that the character of Worf had a presence they made him a regular character on the series.
  • Due to the sheer number of appearances in TNG, DS9, and films the character of Worf currently holds the record of the most appearances in all of Star Trek.
  • Dorn also portrayed Worf's grandfather in Star Trek VI: The Undiscovered Country.
