Worf (Klingon: wo'rIv) is a Klingon Starfleet officer in the Star Trek fictional universe. This character appears in the television series The Next Generation and Deep Space Nine and in movies based upon The Next Generation series. Worf is played by actor Michael Dorn. He was the first regular Klingon character to appear in Star Trek and has also appeared in more Star Trek episodes than any other character (TNG years 1-7, DS9 years 4-7, Star Trek movies 7-10) and the only actor to be a regular character in two Star Trek series playing the same character. Colonel Worf, who appeared in The Undiscovered Country and who was also played by Dorn was Worf's grandfather.
__TOC__
It was during his time on Gault that the 13-year old Worf, captain of his school's soccer team, accidentally killed another boy named Mikel during a championship game by throwing himself at him as the two children went after a ball that flew into the air. This resulted in Worf's head colliding with Mikel's, breaking the boy's neck. Worf would later explain to his then-girlfriend and future wife Jadzia Dax in the fifth season episode "Let He Who is without Sin..." that up until this event, he was the biggest, strongest and most fearless boy on the planet, uncontrollable, and that he did as he pleased; following this event, overcome with guilt, he realized that he must always practice restraint due to the fragility of humans. This sense of caution became a part of his personality, and at times prevented him from enjoying himself.
Worf became the first living being to undergo a surgical procedure involving a genitronic replicator. After an injury in a cargo bay, Worf's spine had been severed - even normal 24th century technology was unable to completely repair the damage. Normal 24th century treatments would've allowed Worf to walk, but would've restricted his mobility. Dr. Toby Russell, who invented the genitronic replicator suggested that she use it to give Worf a new spinal column. Despite opposition from Dr. Crusher, Russell was allowed to proceed when Worf made it clear that he would rather die than live paralyzed. Crusher and Russell were able to give Worf a new spinal column; he suffered complications after surgery and even appeared to die, but the redundancies in Klingon anatomy allowed Worf to be revived and make a complete recovery.
One of the emblems on Worf's sash is the crest of the House of Mogh, which he continued to wear even after Klingon Chancellor Gowron stripped the House of its title and properties in retaliation for Worf's refusal to join in the Klingon invasion of Cardassia ("The Way of the Warrior"). During the buildup to the Dominion War, Worf developed a rapport with then-General Martok ("Soldiers of the Empire"), and Martok invited Worf to be a part of his family; Worf then replaced the old crest with that of the House of Martok. From this point forward, Worf was regarded as Martok's brother, and as much a member of his family as a biological one.
As a result of his parents' death, Worf has a deep and lasting suspicion of the Romulans. Following his excommunication from the Klingon Empire by Chancellor Gowron in "The Way of the Warrior", his brother Kurn's memory was erased, in order to provide with a new identity as a way to escape the dishonor and prescribed ritual suicide that would have resulted from this event. Kurn is currently living with the family of his father's friend Noggra; Kurn now has the identity of Rodek, believing, as Noggra told him, that he is Noggra's son, and lost his memory after being hit by a plasma discharge, as depicted at the end of the fourth-season episode "Sons of Mogh".
Prior to his posting on the Enterprise, Worf was involved with a Klingon-Human hybrid named K'Ehleyr. During the second season she came onboard the Enterprise to help track down a Klingon ship whose crew had been in hibernation for 75 years, and who were unaware of the current alliance between the Klingons and Federation. The two conceived their son Alexander during this time. Two years later K'Ehleyr died at the hands of Duras, who was subsequently killed by Worf shortly afterwards.
While traveling between parallel universes in the episode Parallels, in several of the universes Worf learned that he and Deanna Troi had become close after his spinal injury, and eventually married. Upon returning to the real universe, Worf and Troi soon became romantically involved, and had gone on several dates by the ending of The Next Generation television series.
Worf and Troi ended their romantic affiliation following the destruction of the Enterprise-D at Veridian III and Worf's reassingment to Deep Space Nine. He then fell in love with fellow officer Jadzia Dax, and the two were married during the sixth season of Deep Space Nine, shortly after the Federation had retaken the station from the Dominion. Jadzia began treatments which would've allowed her and Worf to conceive a child. The two were married less than a year when tragedy struck - Jadzia was attacked by the Pah-Wraiths when Dukat came onboard the station to destroy an Orb of the Prophet. Julian Bashir was able to save the Dax symbiont, which was sent back to the Trill homeworld to be rejoined with a new host, but Jadzia died shortly afterwards.
The Dax symbiont was eventually implanted into a new host named Ezri Dax. She was also posted to Deep Space Nine, and this led to a number of awkward moments between her and Worf. Eventually the two settled into a comfortable friendship, and Dax began a relationship with Julian Bashir.
Later, during the Dominion War (in the DS9 episode Tacking Into the Wind), Worf became concerned with the futile and dangerous assignments being given by Chancellor Gowron to General Martok, in an attempt by Gowron to counter Martok's growing prestige. Motivated by a conversation in which Ezri Dax asks Worf to name the last Klingon leader he could truly respect, Worf challenged Gowron to a duel and killed him. Worf is immediately offered the Chancellorship, but he declines it, and with his encouragement General Martok becomes Chancellor of the Empire.
As with Captain Picard, DarkMateria also released a song about Worf. Like the Picard Song, it featured memorable quotes from Worf mixed with a techno beat and some Klingon music and singing.

Nemesis implies that Worf remains on board the Enterprise-E following the film. It is possible he becomes the new first officer of the ship in the post-Nemesis novels from Pocket Books, but this is not confirmed. The first novel where Worf might hold this position is Resistance'' by J. M. Dillard, to be published in September 2007.
