‘Deep Space Nine’s Best Crossover Character Changed the Show Forever

The Big Picture

• Worf’s arrival on
  Star Trek: Deep Space Nine
  deepened the exploration of Klingon culture and his personal identity.
• Worf’s relationship with Jadzia adds depth to his character and highlights his humanity.
• Worf’s struggles adjusting to life on DS9 test his loyalty, friendship, and honor.

Worf, son of Mogh (Michael Dorn), is a beloved character initially introduced to audiences in Star Trek: The Next Generation, known for his battle-hardened stoicism and the comedic relief that his upright and rigid demeanor brings. Worf crossed over to Deep Space Nine in the fourth season, much to the delight of Star Trek fans. Initially, his arrival on DS9 allowed the show to explore the Klingon Empire in-depth by extrapolating his inner conflict between his roles as a dutiful Federation Officer and a fierce Warrior of The Klingon Empire.

However, Worf’s presence on DS9 would also forever change the series, allowing a deep exploration of the machinations of the Empire through its saga with Gowron (Robert O’Reilly). His relationship with Jadzia (Terry Farrell), a Trill learned in the ways of the Klingon, would help highlight Worf’s humanity, act as a romantic counterpoint to his rigidity, and provide context for the curious observer. Jadzia and Worf are similar in some respects, as they both have multiple identities to reconcile. Jadzia would be the first non-Klingon woman that Worf could be with in the traditional sense, giving a vulnerability to the character that would carry on throughout the series and provide a deep richness to DS9 that helped cement it as a critical series in the Star Trek universe.

What Is ‘Deep Space Nine’ About?

Star Trek: Deep Space Nine is the fourth series in the Star Trek universe, created by Rick Berman and Michael Piller. Deep Space Nine ran from January 3, 1993, to June 2, 1999, for 176 episodes over seven seasons. It was the first Star Trek series to be created without the involvement of series founder Gene Roddenberry, the first to be set on a space station, and the first to boast a Black captain in Benjamin Sisko (Avery Brooks). The series follows the exploits of a hybrid crew of Starfleet and Bajoran officers on the titular space station, in orbit above Bajor and adjacent to a wormhole leading to the distant and mysterious Gamma Quadrant. Starfleet has come to oversee the transfer of power from the oppressive Cardassian Empire to the Bajoran civilian government, which has been under the heel of the Cardassians for some time.

The series is much darker than its predecessors. At one point, Major Kira Nerys (Nana Visitor), the first officer of Deep Space Nine, is a Cardassian prisoner of war, and even Sisko himself saw his wife killed during a Borg raid on a space station. The currents of trauma that run through the ensemble invoke feelings of loneliness, desperation, and fear, which the characters must overcome in typical Starfleet fashion. The well-roundedness of the characters makes them very compelling and adds a layer of sophistication to the series, which, while present in its predecessors, came into its own during DS9 and became a recurring theme on the show.

One particular theme that runs through Deep Space Nine is the duty to one’s station and the duty one has towards one’s individuality. This exploration of where duty and individuality meet is present in many characters. Take Odo (René Auberjonois), for example, a Founder separated from his people and planted firmly in the camp of the Alpha Quadrant. In contrast, his people wage war on the planets of the Federation. Odo must choose between his people, Starfleet, and his cultural identity and individuality. So, too, must Kira, whose hatred for the Cardassian is a defining feature of her character, and who has to learn to overcome this so that it does not interfere with her duties to Starfleet. This war between the Founders, their allies, and Starfleet is the primary conflict in the series. They are a formidable race of shapeshifters backed by the Jem’Hadar, a warrior race of beings whose soul existence is to crush opposition. They are a tough, genocidal race, terrifying in their methods and fearsome enough to give the Klingon Empire a run for its money.

Worf’s Arrival Changed ‘Deep Space Nine’ for the Better

Worf joins the crew of Deep Space Nine during the feature-long premiere episode of Season 4 in “The Way Of The Warrior.” At the beginning of the episode, the Klingon Empire, led by Gowron, shows up at the space station to aid them in their fight against the Founders. This is a serious boon for Starfleet and the Alpha Quadrant, as the Klingons are such fearsome and brutal fighters that they may tip the balance of power throughout the war. But they push things too far, illegally searching Bajoran ships and starting a war with the Cardassians, whom they believe to be comprised of the shapeshifting Founders. Worf is brought to gather intelligence by reaching out to the Empire. He is very close with Gowron, who has absolved Worf and his family of their generations-long disgrace. Worf learns of the Klingon plans to invade Cardassia and must choose between fulfilling his duties to Starfleet or joining Gowron in battle. Worf’s choice to maintain his honor by remaining in Starfleet is a moral choice that tests his individuality against those of his bloodthirsty cultural traditions.

Throughout the series, Worf meets Deep Space Nine’s chief science officer, Jadzia Dax, a Trill and the host of the symbiont that once belonged to Curzon Dax. Due to the Dax symbiont carrying all its previous hosts’ memories, Jadzia can tap into Curzon’s familiarity with Klingon customs. The characters are exciting foils to one another. Worf is glib, stoic, and utterly humorless, while Jadzia is more irreverent and open, owing to the many past lives she recalls through her symbiont. However, the two also have more in common than one might think; they are both people who have multiple identities. The critical difference is that Jadzia has reconciled her identities, while Worf remains at odds with his.

Jadzia is the only person aboard Deep Space Nine who can genuinely understand Worf, and it is this factor that blossoms their innocuous meeting into what may be one of the most fantastic love stories ever told in the Star Trek universe. Their connection is marvelous as their conflicting natures are both points of contention that allow for humorous moments where Jadzia’s tenderness assuages the beast within Worf. It is delightful to watch Worf babysit chief operations officer Miles O’Brien’s (Colm Meaney) daughter, paving the way for the couple to conceive a child of their own — which is made all the more tragic by Jadzia’s murder and Worf’s spiral into despair.

Worf Had a Difficult Time Adjusting To Life On Deep Space Nine

Initially, Worf has his former Enterprise crewmate O’Brien to help ease his transition into life on the space station. The two were close, and their relationship strengthened on The Next Generation, after Worf helped O’Brien’s wife Keiko (Rosalind Chao) give birth to their daughter. When Worf joins the crew of DS9, O’Brien is among the first to receive him to help him acclimate — introducing him to Doctor Julian Bashir (Alexander Siddig), a rival suitor for Jadzia’s affections and eventual boyfriend to Ezri (Nicole de Boer), who becomes the host of the Dax symbiote after Jadzia’s untimely death.

O’Brien is the only person Worf can genuinely confide in after the death of his wife, and he heartbreakingly confesses to his friend that he fears Jadzia’s soul may never make it to Klingon heaven because she hadn’t eaten the heart of her enemy after a night of too much blood wine. Worf longs to be with his wife in the afterlife, making Ezri’s relationship with Bashir a sore point for the commander. But Worf eventually becomes a friend to Ezri, who, in effect, helps Worf to properly grieve Jadzia’s death so that he can move on and step up to be the man that the Klingon Empire needs.

It isn’t an easy transition for Worf after he accepts the commission of Special Operations Officer on Deep Space Nine — yet Captain Sisko has incredible foresight when he offers Worf the position. He sees Worf as a profoundly knowledgeable and capable military strategist whose intuition and extensive knowledge of warfare, particularly Klingon warfare, would greatly benefit the station and Starfleet. This position puts Worf in direct opposition to his people and weighs heavily on his mind. By siding with Sisko over Gowron, Worf again sees himself as an outsider among his people. His frustrations are palpable, but he can sublimate these into his work and subsequently earn a place of deep respect in Sisko’s heart. It is summed up rather nicely between the two with a hearty handshake when Worf accepts the role of Ambassador to the Klingon homeworld.

Until this point, Worf wants to restore his family’s honor, and ironically, he loses it again while pursuing what he believes to be honorable. Here is the show’s crux: how far someone is willing to go to do what they believe to be correct. Sisko tests the bounds of his morality while making difficult choices about defeating the Founders. Odo turns his back on his people. On the fringes of the known universe, a brave crew of deeply traumatized heroes will learn exactly that. Worf’s crossover on Deep Space Nine marks the point where the series descends into a dark rabbit hole spurned on through the fog of war, but it also results in some of the best character relationships within the Star Trek universe.
