Summary
Star Trekhas a utopian vision of the future. In this sci-fi series,numerous alien species come together for the common good. That sense of hope is one reason that fans connect with the franchise, as it provides some much-needed optimism going forward. However, that enduring positivity has another effect.
Namely, it makes each death more potent.Star Trekexemplifies that deep impact with several notable passings. These fatalities shocked fans the world over, showing that the galaxy was not as friendly as they’d surmised. In some cases, they irreparably altered the entire series' trajectory. For those reasons, the deaths here are still a sore spot for many Trekkies. Such tragic scenes rockedStar Trekto its very core.

1Spock
The Series' Most Popular Character Makes A Logical Sacrifice All The More Painful
The franchise’s most famous death befalls its most iconic figure. DuringThe Wrath of Khan,Spockrepairs the warp drive so that theEnterprisecan fly out of danger. Doing so requires taking a radiation blast head-on, and he dies soon after. However, he tells Kirk not to grieve,stating that it is the logical option. He even calls back to their earlier conversation about the needs of the many outweighing the needs of the few (or the one). It’s a touching scene and a heart-breaking end to arguably the bestStar Trekfilm, which builds on the series' legacy while crafting a compelling tale about mortality amid new horizons.
This bold move epitomizes that mission.Star Trekhad seen casualties before, but never one of the core crew. The main characters had always seemed untouchable in that respect, either due to plot armor or their own expertise.

Fans certainly wouldn’t expect Spock to go out like this. Not only is he the most recognizable character in the series, but he’s always been logical and devoid of emotion. Such a man isn’t the sort to sacrifice everything for his friends. That’s what makes this moment so beautiful. It’s a culmination of these heroes' storied history which reaffirms the bond they share. As such, his death is earned and oddly satisfying. Truly, humanity can come from any being, no matter how alien.
2James T. Kirk
A Meeting Of Two Legends Ends With One Giving His Life
Nearly as popular as Spock is his captain.James T. Kirkreturned to screens inStar Trek: Generations, where he met Jean-Luc Picard. Together, they stop a villain wishing to use the mysterious Nexus for his own purposes, but the battle costs Kirk his life. Thankfully, he takes comfort in the fact that they accomplished their mission.
That fact is particularly rewarding for him. He’s been grappling with feelings of irrelevance for several films.Those feelings led him to wallow away in the Nexus, unwilling to lift a finger to aid Picard. Therefore, it’s gratifying to rediscover his sense of purpose and heroism. Granted, it could have happened in a better movie, but that’s beside the point. Like Spock, Kirk’s death has important ramifications.

Namely, it’s a decisive end to the original era. From here, the movies shift entirely to theNext Generationcast. True, the characters returned in the 2009 reboot and subsequent TV shows, but this is their last time played by the old actors. By extension, it’s William Shatner’s last hurrah as Kirk. Considering how he defined the character, that’s worthy of a moment of silence. On a more hopeful note, it shows howStar Trektranscends any individual.
3Jadzia Dax
A Sudden Attack Robs DS9 Of A Beloved Wife And Mentor
Deep Space Ninedeveloped a reputation as a darkerStar Trekshow, and it unfortunately cemented that impression in its sixth season.Jadzia Daxstumbles on Gul Dukat rooting around the Prophets' temple. He then uses power gained from the devilish Pah-wraiths to mortally wound the heroine. In the season’s final moments, she passes away.
Star Trekhad previously killed mainstay characters, but it was still a rarity. In fact, the creators mostly reserved such tragedy for the movies.DS9showed it was possible on the small screen. The result was no less devastating.

Fans see how poignantly Jadzia’s death affects not only her husband,Worf, but the crew. The loss of his mentor and friend sends Captain Sisko into a deep depression. He was always a stalwart figure, providing some much-needed surety during the Dominion War. For him to abandon the fight makes the whole situation seem truly hopeless. True,his absent comrade returns in some form as Ezri Dax, but her inexperience makes for a completely different dynamic. Her interactions with the crew are bittersweet, especially when comparing her to Jadzia. These factors make the final season a trying time for all involved.
4Data
The Goofy Robot Gets Serious To Save His Friend And Captain
The time also came for theNext Generationera to bow out.Star Trek: Nemesissees Picard trapped on an enemy ship about to explode.Dataleaps over and uses an emergency transport device to beam the captain aboard theEnterprise, dooming himself in the process. The act is one of instinct and desperation, neither of which people associate with this character.
Data is an androidpossessing an emotional distance similar to Spock. The difference is that the creators use him for more comedic relief, as he has a childish misunderstanding of human interaction. However, it’s still shocking that he would sacrifice himself to save Picard. It’s arguably more impactful to include such a depressing resolution to an oblivious figure of fun. Clearly, Data cared for his friends on a level they didn’t realize. The momentary sadness wasn’t the only consequence.

Data’s demise informed theNext Generationcast’s exploits going forward. First, it echoed Kirk’s death in that it ended the crew’s tenure on the big screen, lending a sense of finality beyond the character himself. That impact manifested further as the face of Picard’s personal conflict in his own show. The quality of these tales may be up for debate, but there’s no denying the ripple effect of this robot’s passing.
5Most Romulans & Vulcans
Wiping Out Two Civilizations Changes The Course Of The Whole Series
The 2009Star Trekflick strives to take the old characters on new adventures. The filmmakers want a clean slate, and they destroy two whole worlds to get it. After an elderly Spock fails to save the Planet Romulus from a supernova, he and a surviving Romulan named Nero find themselves sucked into a black hole and deposited in the past. As his revenge, Nero destroys Spock’shome planet of Vulcan. This act kills most of the inhabitants, including Spock’s mother. The whole ordeal is equal parts implausible and catastrophic.
Star Trekwas no stranger to destruction. Fans had seen plenty of ravaged worlds, but the series rarely snuffed out an entire planet. The idea is insane and makes viewers wonder what else the filmmakers have in store. That fear is prophetic.

These events alterStar Trekhistory, firmly solidifying this new timeline as uncharted territory. The subsequent films continue from this fresh starting point. Granted,later shows return to the old continuity, but the creators still operate under the modern mindset of action and large-scale destruction. Meanwhile, the alternateKelvintimeline is just waiting for filmmakers to continue it. Who knew that the death of two planets could revive the franchise two-fold? It’s just a question of whether it remains trulyStar Trekin spirit.
