"Microbrain" (The Next Generation) Worf, son of Mogh is a fictional character in the Star Trek franchise, portrayed by actor Michael Dorn.

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.

[8] 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.

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.

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.

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.

In appreciation of his support, Chancellor Gowron restored Worf's honor, allowing Kurn a seat on the High Council as the recognized brother and representative of the House of Mogh (TNG: "Redemption, Part I").

Once the war was over, Worf regained his Starfleet commission, recognizing that he did not fully belong to Klingon society (TNG: "Redemption, Part II").

Unable to return home with honor, as Klingons are supposed to commit suicide rather than be taken prisoner, they stayed and strayed from their way of life.

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.

The Klingons attacked the station in order to capture the council members but withdrew as Starfleet ships approached, fearing a war on two fronts.

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.

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.

The discovery helped restore peace between the Federation and the Klingons and to Worf again being shunned by Gowron for not having killed him when he had the chance, reaffirming his dishonor.

The entry of the Klingon ships turned the tide and allowed the Defiant to break through and retake the station (DS9: "Favor the Bold", "Sacrifice of Angels").

In the DS9 episode "Change of Heart", Worf prematurely ended a mission to contact a Cardassian informant inside the Dominion in order to save his injured wife.

By late 2374, Worf and Jadzia were married less than a year when they decided to try to have a child, despite the extreme difficulties posed by the disparate biologies of Trill and Klingons.

(DS9: "Time's Orphan", "Tears of the Prophets") Julian Bashir was able to save the Dax symbiont, which was sent back to the Trill homeworld to be rejoined with a new host aboard the USS Destiny.

He dedicated this mission to his late wife, in order to ensure her entry into Sto-Vo-kor, the Valhalla-like realm of the honored dead, being joined by Quark, Bashir and O'Brien (DS9: "Shadows and Symbols").

After the conclusion of the Dominion War, Worf was offered the position of the Federation ambassador to Qo'noS (the Klingon homeworld), as depicted in the Star Trek: Deep Space Nine series finale "What You Leave Behind".

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.

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.

[14] The series finale of Webster had the titular character go into the future to the Enterprise-D bridge, where he encounters several unnamed Enterprise crew members and Worf.

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.

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.

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.

[33] Worf is ranked the 13th most important character of Starfleet within the Star Trek science fiction universe by Wired magazine, beating out such favorites as Uhura.

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".
