Worf, son of Mogh is a fictional character in the Star Trek franchise, portrayed by actor Michael Dorn. He appears in the television series Star Trek: The Next Generation (TNG), seasons four through seven of Star Trek: Deep Space Nine (DS9), and the third and final season of Star Trek: Picard, as well as the feature films Star Trek Generations (1994), Star Trek: First Contact (1996), Star Trek: Insurrection (1998), and Star Trek: Nemesis (2002).
Worf is the first Klingon main character to appear in Star Trek. In 11 seasons as a regular character on TNG and DS9, plus appearances as a recurring character in Picard, Worf has appeared in more Star Trek franchise episodes than any other character.

Casting
Initially, Worf was not intended to be a regular character, as Gene Roddenberry wanted to avoid "retreads of characters or races featured prominently in the original Star Trek series". Accordingly, a cast portrait released in June 1987 to promote the upcoming series did not include Worf. Several "tall, slim, black actors" auditioned for Worf before Michael Dorn came along. Not only did the Worf character become a regular on The Next Generation (TNG), he was continued on the Deep Space Nine (DS9) series for four more seasons (1995–99) and talk of a spin-off Worf show continued even into the 2010s.
He made his debut in 1987 in "Encounter at Farpoint", and last appeared in character in 2023 in Picard season 3. Dorn as Worf made 283 on-screen appearances, the most of any actor in the Star Trek franchise.
Family history
Worf was orphaned as a child as a result of the Khitomer Massacre, and raised by humans Helena and Sergey Rozhenko. In one episode, the character says he was raised on the farm world Gault and in others he says he was raised in Russia near the Ural Mountains. He experiences conflicts between his upbringing and his desire to honor his biological heritage. He has two brothers, each with their own respective backstories, as well as two adoptive human parents, and one son. Important Star Trek episodes for Worf's family include "The Bonding", "Sins of the Father", "Family", "Reunion" and "Homeward" in The Next Generation, and "Sons of Mogh" and "You Are Cordially Invited" in Deep Space Nine.
The House of Mogh was a family of high social and political rank, and was for a time represented on the Klingon High Council. In Star Trek VI: The Undiscovered Country (set around 70 years before the Next Generation era began), Colonel Worf (also portrayed by Dorn) appears as the legal advocate of Captain James T. Kirk and Dr. Leonard McCoy after they are accused of killing Chancellor Gorkon of the Klingon High Council. He was also a member of the Klingon delegation at Camp Khitomer. Although not explicitly stated, he was intended to be Worf's grandfather and namesake.
Worf has a son named Alexander with a half-human half-Klingon woman named K'Ehleyr, a character introduced in "The Emissary"; however, she is later killed in "Reunion", a "sequel" to that episode and part of the Worf story arc, leaving Worf as a single parent. Alexander has to live aboard Enterprise-D when K'Ehleyr is killed. After TNG ends, Worf gets moved to the Deep Space Nine space station where he eventually marries the Trill symbiont Jadzia Dax. (See "You Are Cordially Invited".) On DS9, Worf misses the Enterprise-D "family" that he had, often bemoaning the cut-rate work ethic and unfriendliness on the wayward outpost.
The episode "Sins of the Father" introduces Worf's long-lost brother Kurn, who is also an orphan of the House of Mogh. Worf's adoptive parents have a biological son, Nikolai Rozhenko, with whom Worf grew up. Nikolai and Worf talk in "Homeward", where it is revealed that Worf will likely have a nephew or niece.
In "The Bonding" (TNG S3E5, aired 1989), Worf adopts an orphan boy into the House of Mogh. In the first Star Trek episode written by screenwriter Ron Moore, the orphan Jeremy (played by Gabriel Damon) has a special Klingon ceremony to be adopted into Worf's family.Join me in the R'uustai, the Bonding. You will become part of my family now and for all time. We will be brothers.
Storylines
Backstory
Worf was born in 2340 on Qo'noS (the Klingon homeworld) as the son of Mogh. Five years later, his parents moved to the Khitomer colony. Worf's parents were killed during a surprise attack by the Romulans on the Khitomer outpost. The colony's distress call was answered by the Federation starship USS Intrepid. Chief Petty Officer Sergey Rozhenko found Worf in the rubble and took him in after failing to find any living relatives. Rozhenko and his wife Helena raised him on a small farm colony on the planet Gault, a world of about 20,000 inhabitants, almost all of them human. Worf also has a human brother, Nikolai, with whom he often quarreled. He also spent time on Earth in his parents' native city of Minsk, later recommending it to Miles O'Brien as one of his favorite places on Earth.
Worf did not take the Rozhenkos' last name, preferring to be addressed by the Klingon designation, "Worf, son of Mogh". However, his son, Alexander Rozhenko, who was raised by the Rozhenkos after his mother, K'Ehleyr, died, did use their surname. Although Worf was raised by humans, he considered himself a Klingon at heart and studied in-depth the ways of his people. As an adult, his mannerisms and personality, as well as his innate sense of honor, became more Klingon than human.
Worf's brother Kurn, barely a year old at the time of the Khitomer attack, had been left behind on the Klingon homeworld Qo'noS by his parents. Lorgh, a friend to House of Mogh (appearing only in dialog of the episode "Sins of the Father"), was charged with the care of the younger son, originally expecting Mogh's stay at the Khitomer outpost to be short-term. Lorgh adopted Kurn after the attack, but informed Klingon authorities that he had died with the rest of the family. Kurn was not revealed as being alive until both brothers were adults.
In 2357, Worf entered Starfleet Academy. He graduated in 2361 and was commissioned with the rank of Ensign, becoming the first Klingon officer in Starfleet. Although Worf took immense pride and a sense of honor from serving in Starfleet, most other Klingons shunned and belittled his choice of vocation.
In 2359, he became briefly involved with K'Ehleyr who was the daughter of a Klingon father and a human mother.
The Next Generation
In 2364, Worf was assigned to the USS Enterprise-D as relief flight control and tactical officer with the rank of lieutenant junior grade (TNG: "Encounter at Farpoint") under the command of Captain Jean-Luc Picard. The next year, he was made Acting Chief of Security following the death of Tasha Yar, even though he believed that a promotion due to the death of a comrade was not honorable (TNG: "Skin of Evil"). The next year, he transferred to operations division and was formally made Chief of Security (TNG: "The Child").
In 2365, he renewed his relationship with K'Ehleyr when she came aboard the Enterprise as a Federation emissary on an urgent mission. He proposed marriage but was rejected (TNG: "The Emissary").
In 2366, he was promoted to Lieutenant (TNG: "Evolution"). After an accident caused the death of Lt. Marla Astor, Worf brought the orphaned Jeremy Astor into the House of Mogh through the rite of R'uustai (TNG: "The Bonding").
Worf learned of Kurn's existence when Kurn was assigned to the Enterprise as an exchange officer. Kurn specifically asked for the Enterprise so he could observe his brother. He then revealed his true identity, informing Worf that the House of Mogh's rival Duras accused their father of betraying the Klingon Empire by helping the Romulans attack Khitomer. When they and the Enterprise crew discovered that it was in fact Duras's father who betrayed the Empire, Worf, realizing that the powerful House of Duras could not be publicly shamed without throwing the Empire into civil war, accepted a ritual discommendation from the Klingon High Council. While Worf decided to accept this dishonor, it was decided to keep Kurn's true identity secret in order to protect his honor (and the House of Mogh as a whole be left alone) (TNG: "Sins of the Father").
In 2367, K'Ehleyr returned with Klingon Chancellor K'mpec who had come to meet with Captain Picard. When she came aboard, Worf learned he had a son named Alexander. She wanted to marry him but Worf refused because he did not want to share his dishonor with her and their son (TNG: "Reunion").
After K'mpec's death, she assisted Captain Picard with the rite of succession. K'Ehleyr was eventually murdered by Duras when she found evidence of his involvement in the effort to discredit Worf (and why he was discommended). Exercising his right of vengeance, Worf fought and killed Duras with a bat'leth in a duel, allowing Duras's political opponent Gowron to become chancellor (TNG: "Reunion").
Deep Space Nine
In 2371, he was promoted to lieutenant commander (Star Trek Generations). After the destruction of the Enterprise-D, Worf took an extended leave to evaluate his future. He was at a monastery on the Klingon colony of Boreth when he was ordered to go to Deep Space Nine to advise Captain Sisko when a Klingon fleet massed at the station. When he arrived, he was met by former Enterprise-D crew member and Deep Space Nine Chief of Operations Miles O'Brien. (DS9: "The Way of the Warrior").
Worf learned that the Klingons were planning to invade Cardassia because of a coup which they had been led to believe was engineered by the Dominion. Worf reluctantly informed Sisko, knowing this would jeopardize his status in the empire. After the invasion had begun, Gowron traveled to DS9 to ask Worf to join him in battle. Gowron believed the Federation was unworthy of Worf's loyalty because they would not fight the Dominion. Worf felt the war was wrong and he could not support it. Gowron punished him by reinstating Worf's discommendation, but this time executing it to the full degree, by stripping him and his family of his honor, lands, and titles, effectively bringing down the House of Mogh.
Worf submitted his resignation but Sisko rejected it because he still needed him. He had decided to rescue the members of the Cardassian council from certain death at the hands of the Klingons. In doing so, he was able to prove that there was no Dominion involvement by verifying their identities. The Klingons attacked the station in order to capture the council members but withdrew as Starfleet ships approached, fearing a war on two fronts.
At the end of the immediate crisis, Sisko convinced Worf to join the crew as Strategic Operations officer. In this role, he would coordinate all Starfleet activity in the Bajoran sector and act as executive officer of the USS Defiant, meaning he had to adjust to the requirements and obligations that came with the red "command personnel" uniform. For the first months, Worf had difficulties adjusting to life on the station, unintentionally overstepping his boundaries by acting as he did on the Enterprise, putting him for a while at odds with Chief of Security Odo. For Worf, the station's life seemed just too much 'grey', subsequently requesting to relocate his quarters aboard Defiant.
After the Klingon civil war, Kurn had gained a seat on the High Council. Worf's opposition to the war against Cardassia cost Kurn his seat on the council. Four months later, he arrived at DS9 seeking help from his brother to perform a ritual to die with honor. He felt that the ritual, which involved Worf killing him, was the only way to restore his honor. Initially disregarding orders from Sisko not to carry out the honor killing, Worf failed in his first attempt to perform the ritual and later found he could not bring himself to do so again, as he had taken on a human feature of morality and would consider it murdering his brother. Worf arranged for his brother to have cosmetic surgery and his memory wiped so he could start a new life with no ties to the House of Mogh. Kurn now has the identity of Rodek, who believes he lost his memory after being hit by a plasma discharge (DS9 episode "Sons of Mogh"). When Rodek sees Worf, he asks him whether he is family. Worf bitterly replies that he has no family.
Star Trek films
Worf continued to appear in TNG films, which is explained in various ways, such as being rescued from the damaged Defiant during a battle with the Borg (Star Trek: First Contact) and taking leave that led to him traveling on the Enterprise (Star Trek: Insurrection). Star Trek: Nemesis was released after the conclusion of DS9 and Worf's status at this time is unclear, although the novelization stated that Worf returned to Starfleet as he found life as an ambassador unsatisfying. Worf attended the wedding of William Riker and Deanna Troi on Earth and traveled to Betazed with the Enterprise crew for the second wedding ceremony when the ship was diverted to investigate positronic signals from a system near the Romulan border.
Star Trek: Picard
By the time of Star Trek: Picard, Worf has become a subcontractor for Starfleet Intelligence, having attained the rank of Captain and briefly commanded the Enterprise-E beforehand. Worf has mellowed with age, no longer giving in to impulse; even adopting a fondness for meditation and tea in his free time, having seemingly given up Klingon opera. It is also revealed that something happened to the Enterprise-E under Worf's command that renders it unusable by the time of Star Trek: Picard, something that Worf insists was not his fault.
A contact (heavily implied to be Odo) has made Worf aware that a group of Changelings objected to the Dominion's surrender and began a campaign against the Federation, prompting Worf to mount an investigation into their activities, assisted by Raffi Musiker and supervised by Ro Laren. Worf and Raffi interrogate multiple criminal co-conspirators, including the Ferengi Sneed and the Vulcan Krinn, finding that the Changeling group has infiltrated the highest levels of Starfleet and burgled its most advanced lab the Daystrom Institute to restart the Dominion War. He is reunited with Picard and the rest of the Enterprise crew, including a resurrected Data, throughout the third season, whereupon he helps Picard defeat the Changelings' collaborators, the Borg, using the rebuilt Enterprise-D. Worf also helps Musiker reunite with her estranged family by secretly leaking her heroic deeds to them. He is last seen playing poker with his Enterprise crewmates at the Ten Forward bar in Los Angeles, content with his life.
Alternate versions
In 2370 after returning from a tournament, Worf encountered a quantum fissure and began shifting into different realities. In one reality, he became involved with Deanna Troi while recovering from a spinal injury. He asked permission from Commander Riker to court Troi. By the time the events in this episode takes place, he has been married to her for two years. In another reality, Worf is first officer of the Enterprise, serving under Capt. Riker, who assumed command after Capt. Picard was killed by the Borg. He is married to Deanna Troi and has a daughter Shannara Rozhenko and a son Eric Christopher Rozhenko. However, she doesn't know anything about Alexander (TNG: "Parallels").
In an alternate future, Alexander becomes a diplomat instead of a warrior. He wanted to end the feuding among the great houses and declared that the House of Mogh would no longer engage in blood feuds. Worf warned him that this was a show of weakness but Alexander persisted. Shortly after Alexander's decision, he witnesses Worf being killed on the floor of the High Council. Had he become a warrior, he thinks perhaps he could have saved his father's life. Eventually, he finds a way to travel back in time to try to prevent these events from occurring by convincing his younger self to train to become a warrior while under the assumed name of K'Mtar, but Worf convinces him to return to the future with assurances that he has already changed his own history (TNG: "Firstborn").
In an alternate future, Worf had been reluctant to become involved with Troi and her subsequent death led to a rift between Riker and himself as a result. He later served as a member of the Klingon High Council and was governor of the Klingon colony of H'atoria with his fellow Klingons possibly at the brink of war with the Federation after conquering the Romulan Star Empire. Nevertheless, he helps his old crewmates with the threat of an anti-time eruption, and Riker makes a conciliatory gesture to his old friend, asking for his help on the Enterprise bridge during the situation, which Worf accepts (TNG: "All Good Things").
While on a mission in the Gamma Quadrant, the Defiant detects an energy barrier surrounding a planet in a nearby solar system. When they enter the barrier, the ship is damaged and they detect a settlement with 8,000 people who are mostly human. When they investigate, they learn they have been expected. The settlers explain they are the descendants of the Defiant crew. In a couple of days, when the Defiant tries to leave orbit, they will be thrown back in time two centuries and crash land on the planet. Worf learns he married and raised a family. He meets his descendant Brota who leads the Sons of Mogh. The members are descendants of Worf and Jadzia and others who choose to join them. They follow Klingon customs as first taught to them by Worf (DS9: "Children of Time").
Possible spinoff
Due to Worf's popularity there was some talk of a Captain Worf series prior to the streaming television spinoffs that began in 2017. In 2012, Dorn conceived the idea for a Worf show, and has pitched it at various times in the 2010s. He was reportedly offered a role as a Worf-ancestor on Star Trek: Discovery but this did not come to fruition. In 2021, Dorn, in addressing rumors that he might appear on Star Trek: Picard, said he was still interested in a movie or series with Worf.
References in other media
Worf has appeared in various TV, film, book, and video games, as well as being referenced in non-franchise media such as through satire.
Video games
In Star Trek: Deep Space Nine: The Fallen, Commander Worf is one of the three main playable characters in the computer game Star Trek: Deep Space Nine: The Fallen. In the game the player can play as Worf, and the game had generally favorable reviews, with on reviewer saying it has a "compelling storyline". It was published in 2000 for Windows and 2001 for Macintosh.
In Star Trek: Invasion, Commander Worf is part of the 2000 Sony PlayStation video game Star Trek: Invasion. In the game, the player gets instructions from Worf, and the game received generally favorable reviews.
Television
The series finale of Webster has the titular character go into the future to the Enterprise-D bridge, where he encounters several unnamed Enterprise crew members and Worf. Worf initially tells Webster he cannot return him to his time due to the Enterprise's inability to escape the gravitational pull of a planet, but eventually, they are able to reverse-engineer the process that transported Webster to the future, and return him home. Webster wakes up from what seems to have been a dream.
During the film Ted 2, Michael Dorn appears as a character by the name of Rick. This character in the film attended the New York Comic Con amateurishly dressed as Worf.
Worf, voiced by Michael Dorn, makes an appearance in the animated series Family Guy.
Books and comics
Worf's character is further developed in non-canon media. In Star Trek, the non-live action material is not considered a part of the character's story, although it may use elements from the television and film narrative. In other words, live action appearances don't take into account the stories written in novels for example.
According to the Pocket Books novels set after Nemesis, Worf takes over William T. Riker's position of first officer aboard the Enterprise-E. According to Death in Winter, Worf was to transfer with Riker to the Titan, but after Data's death, Picard asks Worf to stay aboard the Enterprise, and Worf obliges. In early 2380 in Resistance, Starfleet Command approves Picard's request to make Worf the permanent first officer, but Worf refuses as he doubts his command skills (due to his choice of love over duty in "Change of Heart"). Soon afterwards, however, Worf successfully leads the rescue of Picard from another Borg crisis, and is sufficiently convinced to accept the permanent promotion. As of 2385 in the novel miniseries Star Trek: The Fall, Worf continues to remain first officer of the Enterprise-E. According to the Titan series, he also adopted Data's cat Spot.
Worf had a relationship with Enterprise-E Chief of Security Jasminder Choudhury in the books until her death in the 2012 novel The Persistence of Memory by David Mack.
The Pocket Books series continued in the 2016 trilogy Prey, written by John Jackson Miller. In it, Worf and the cloned Klingon Emperor Kahless are drawn into battle with a group of discommendated Klingons, all disciples of the late Kruge, the villain from the movie Star Trek III: The Search for Spock, being manipulated by Kruge's secret heir Korgh. By 2386, Worf's son Alexander is an Ambassador, working alongside Admiral William Riker. The events of Prey conclude with the last survivors of the discommendated Klingons taking on roles as guardians for a planet whose previous guards were killed as part of the conspiracy, with Kahless joining them to help them learn how to be truly Klingon. As acknowledgement of Worf's role in helping them redeem themselves, the group name the first child born during this crisis after Worf.
IDW Publishing took the character in a different direction in its licensed works. In the official comic book prequel to the 2009 movie Star Trek, Worf is a General in the Klingon Empire who is dispatched to deal with Romulan Captain Nero and his significantly altered mining vessel, the Narada, which leads to a confrontation in which Nero impales Worf through the back with a large mechanical tentacle. When the Enterprise-E intervenes, Nero beams Worf to Captain Data, but uses the opportunity to inflict heavy damage on the Enterprise before leaving to attack the planet Vulcan. Worf's status after this is never explicitly mentioned in the comic.
Critical and fan reception
Worf is a decidedly popular character among fans. The episode "Heart of Glory" (S1E20 of TNG), which focuses on Worf and his relationship to other Klingons, is credited with planting "many seeds for successive Klingon storylines ... and new insights into Klingon culture".
With TNG over in 1995, the writers of DS9 came up with the idea of adding Worf to the cast in response to pressure to boost ratings. Screen Rant has rated the character Worf a number of times, and by several authors, at its site. Author Edward Cambro ranks Worf as the 13th best Star Trek character overall, and remarks how Worf had to "walk the line between two cultures, neither of which he entirely understood (nowhere is this more apparent than in episodes like "Sins of the Father," "Redemption II," and "Rules of Engagement")." Said cultures being Klingons and human. Then author Sara Schmidt ranks Worf the 7th most attractive person in the Star Trek universe, in between T'Pol (Enterprise) and Michael Burnham (Star Trek: Discovery), and in another article, she goes on to suggest ideas for a Worf spin-off, saying a young Worf would be "interesting to explore", as well as a "series about Worf's experiences as a Federation ambassador to Qo'noS." Dusty Stowe then ranks the top 8 most powerful characters of Star Trek and places Worf as the most powerful between Spock and Q.
Prominent episodes
Some shows have a major subplot for the Worf character. The first of these debuted in 1988, "Heart of Glory" (which was S1E20 of The Next Generation) This kicked off a long-running story arc that continued until the end of DS9 in 1999 on television and 2002 on film.
In the 2012 book Star Trek 101: A Practical Guide to Who, What, Where, and Why by Terry J. Erdmann, they felt "The Way of the Warrior" was one of three key episodes for the character Worf, along with "The Sword of Khaless" and "Sons of Mogh".
