Spoiler Warning: There are spoilers ahead for the following Star Trek productions: The Search for Spock, The Next Generation Season 3, Nemesis, Deep Space Nine, Voyager, and Star Trek 2009.
Over on Disney+, Marvel has recently put out a series of animated short films with a very interesting premise. These shorts asked what might’ve happened in the Marvel universe if circumstances had changed, characters had taken different actions, or things had ended differently.
Alternate history has always been a subject that fascinated me! So with that in mind, we’re going to consider a few “what ifs” from the Star Trek franchise – from an in-universe point of view, naturally! There are more than 800 Star Trek stories at time of writing, meaning that there are literally hundreds of potential scenarios where a different decision or different outcome could have radically changed the Star Trek galaxy.

As always, please keep in mind that all of this is one person’s subjective opinion! I’m indulging in fan-fiction and pure speculation based on my own thoughts about how some of these scenarios might’ve unfolded. If you hate all of my ideas, or something you like wasn’t included, that’s okay! Within the Star Trek fandom there’s enough room for different opinions.
With that out of the way, let’s consider some Star Trek “what ifs!”
Number 1: What if… Captain Picard couldn’t be saved after being assimilated?

This isn’t going to go the way you might be expecting! In this scenario, the events of The Best of Both Worlds play out as we saw on screen: Picard is captured, the Borg defeat the Federation at Wolf-359, Riker and the Enterprise race to confront them over Earth, and Captain Picard is able to communicate to Data how to defeat them. The Borg cube explodes, and the Federation lives to fight another day! But unfortunately Captain Picard then dies – severing his connection to the Collective and/or removing his Borg implants was too much for his body and mind to take, and he doesn’t survive beyond the end of The Best of Both Worlds, Part II.
As Starfleet and the crew of the Enterprise-D mourn the loss of Captain Picard, Captain Edward Jellico is assigned to the ship as his replacement, and many of the events later in The Next Generation proceed unaltered. As Q would tell Picard in the episode Tapestry, even without him in command the Enterprise-D and Starfleet would be fine.

The Federation, armed with new knowledge of the Borg, developed new ships like the Defiant-class and Sovereign-class, and were even able to defend against a second Borg incursion a few years later – albeit at great cost. But the loss of Captain Picard would have a huge impact later, in the year 2379. A coup on Romulus brings a human clone to power – Shinzon. Shinzon’s plot to destroy the Federation was only stopped because of his personal connection to Picard, a connection that fascinated him and that he hoped could save his life.
Without that obstacle in the way, Shinzon sees no reason to wait or to play nice with the Federation before implementing his plan. He takes his flagship, the Reman warbird Scimitar, and heads straight for Earth before the Federation even has time to respond diplomatically to the change in government on Romulus. Under cloak, the Scimitar deploys its thalaron radiation weapon – massacring all life on planet Earth and crippling the Federation government and Starfleet command.

With war now assured between the Romulans and Federation, Romulan commanders who had been sceptical of Shinzon rally to the cause. All-out war breaks out between the Romulan Empire and the residual Federation, but without a government or command structure to provide a coordinated response, and seriously demoralised from the attack on Earth, things don’t go well for Starfleet. The Scimitar proves to be an unstoppable force all on its own, and its thalaron radiation weapon is able to devastate multiple other planets: Betazed, Andoria, Alpha Centauri, Mars, and others. The Federation is forced to sue for peace on very unfavourable terms.
However, Shinzon wouldn’t live to see the Romulan victory. Without the original Picard, there was no way to save his life from the DNA degradation that he was suffering from, and shortly after the Federation’s defeat Shinzon dies. His Reman viceroy would succeed him as the new leader of the Romulan Empire, an empire which now incorporated large swathes of what had once been Federation space. Whether the Romulans could hold all of this territory, and whether their empire would accept a Reman leader, are now open questions…
Number 2: What if… Spock wasn’t resurrected on the Genesis Planet?

This scenario sees the events of The Wrath of Khan unfold exactly as we saw on screen. Khan stages an attack on the Enterprise, steals the Genesis device, and is defeated at the Battle in the Mutara Nebula. Spock sacrifices his life repairing the Enterprise’s warp drive, allowing the ship to outrun the blast of the Genesis device. But in our alternate world, Captain Kirk doesn’t give Spock a Starfleet funeral. Instead Spock’s remains are returned to Vulcan, in line with his and his family’s wishes. There is no chance for a resurrection because Spock never came into contact with the Genesis Planet.
Spock would indeed prove instrumental in several key events later in his life that now can’t happen. But we’re going to focus on the Kelvin timeline today. Spock’s actions in the Kelvin timeline saved Earth from Nero’s attack – but without his presence there’s no one to stop the crazed Romulan commander.

Assuming that Nero arrived in the Kelvin timeline thanks to Red Matter (presumably deployed by someone else from the Federation as part of a plan to save Romulus), he has no reason to wait for Spock before enacting his revenge plan. After destroying the USS Kelvin (killing the infant Kirk in the process), Nero races to Vulcan and destroys the planet in the year 2233 – decades earlier than he would during the events of Star Trek 2009. Before the Federation even has time to realise what’s happening, and with Vulcan still collapsing, Nero heads to Earth and deploys his weapon for the second time – destroying the planet.
Nero then moves on quickly, targeting Tellar Prime and other Federation member worlds and colonies. The devastating losses mean it takes Starfleet a while to reorganise, but eventually the remaining fleet comes together to make a last stand over Andoria – the last remaining Federation member world. The battle against Nero’s powerful flagship is long and incredibly difficult, but Starfleet eventually prevails through sheer numerical advantage – despite suffering huge losses.

Nero’s defeat wouldn’t mark the end of the rump Federation’s problems, though. With many planets and colonies destroyed, more than half the fleet lost, and millions of people turned into refugees, the Federation is an easy target. First the Klingons come, seizing planets and systems near their borders. Then the Gorn, the Tholians, and the Romulans also join in, picking off star systems that the Federation could no longer manage to defend. Federation space shrinks to a small area in the vicinity of Andoria.
The Andorians were not happy with the large numbers of refugees who sought them out, though. Plans were put in place to resettle humans, Vulcans, Tellarites, and others on new colony worlds, even though doing so would leave them vulnerable. After being kicked out by the Andorians, the remaining Federation members maintained their alliance more out of fear and necessity than anything else. How long these small populations can survive in a hostile galaxy is unknown…
Number 3: What if… the USS Voyager went the other way?

The events of Voyager’s premiere episode, Caretaker, play out much the same as they did on screen in this scenario. But after that, things take a very different turn – literally! The Maquis raider Val Jean, under Chakotay’s command, is transported to the Delta Quadrant by an entity known as the Caretaker. The USS Voyager is likewise transported by the Caretaker’s Array, and after the death of the Caretaker and a short battle with the Kazon, Captain Janeway orders the destruction of the Array. Voyager must find a way home.
Instead of taking the most direct route to Earth, Captain Janeway and the crew of Voyager consider an alternative idea – heading for the Gamma Quadrant, and the far side of the Bajoran Wormhole. From there it would only be a short journey back to Earth! The crew debate the ideas for a while, and there isn’t a clear consensus. No starship has ever undertaken such a long journey before, so there really aren’t ground rules for route planning when it comes to long-distance interstellar travel.

Using the map above (which is non-canon) as a guide, the crew quickly figure out that both a direct route home via the Delta and Beta Quadrants or an indirect route via the Gamma Quadrant and Bajoran Wormhole are roughly the same length and would take roughly the same amount of time.
The two crews can’t agree at first. Chakotay and the Maquis, keen to avoid going anywhere near Cardassian space and fearing being turned over to Cardassian authorities upon their return, firmly advocate for the Delta Quadrant route. Neelix claims to be familiar with space in both directions and along both routes, but ultimately the decision falls to Captain Janeway.

Somewhat ironically when considering her actions in Endgame, Janeway chooses the Gamma Quadrant route. Why? She’s fearful of the Borg, naturally. Whatever dangers and obstacles may await Voyager in the Gamma Quadrant, she tells her crew, Starfleet has known for years that the Borg’s home territory is the Delta Quadrant. Taking that path seems positively suicidal in comparison, so Voyager will instead head for the Gamma Quadrant terminus of the Bajoran wormhole.
Voyager’s superior technology makes battling the Kazon sects in the area around the Caretaker’s Array relatively easy, but they have to be careful to avoid space claimed by the Haakonian Order – the conquerors of Neelix’s people, the Talaxians. After they leave their starting region, though, the truth is that we simply don’t know very much at all in canon about this area of space. Would Voyager find a faster way home through some technological means or natural phenomenon? Or would the ship and crew have to undertake a slow, decades-long journey to reach the wormhole? Would they even survive at all, or instead fall victim to some villainous faction or dangerous anomaly present in this unexplored region?
Number 4: What if… the USS Discovery didn’t go into the far future?

I already have a theory discussing in detail why I think the USS Discovery didn’t need to go into the far future based on the outcome of the battle in Such Sweet Sorrow, Part 2 – and you can find that one by clicking or tapping here. For the sake of this scenario, though, all we’re going to say is that somehow Captain Pike, Burnham, and Saru figured out a way to defeat the Control AI without sending the USS Discovery into the 32nd Century.
Obviously some changes wouldn’t appear until the 32nd Century. Without the USS Discovery and Michael Burnham, no one is able to discover the source of the Burn or the huge cache of dilithium in the Verubin nebula. Without the USS Discovery and its Spore Drive to fight over, the Emerald Chain doesn’t stage a bold attack on Starfleet HQ. Su’Kal would almost certainly die alone when the KSF Khi’eth is destroyed – whether that event would trigger a second Burn is unclear.

But more substantial changes could have taken place in the Star Trek galaxy centuries earlier. With the Spore Drive still in existence in the 23rd Century, it stands to reason that Starfleet would have continued to explore the technology – it works, after all, so if a new way of navigating the mycelial network could be discovered, the Spore Drive would be an absolute game-changer for the Federation.
At some point, Starfleet scientists would hit upon the idea of using empaths to connect to the mycelial network in place of augmenting human DNA. After promising test flights using Betazoid and even Vulcan navigators, in the late 23rd Century Starfleet is able to begin a wider rollout of the Spore Drive. At first a handful of ships are kitted out as rapid-response vessels, able to jump across Federation space at a moment’s notice to assist with emergency situations.

The Spore Drive would soon attract the attention of other factions, however. Unwilling to allow the Federation a massive tactical advantage, particularly in the aftermath of the Federation-Klingon war, the Klingon Empire begins development on their own Spore Drive programme. The Romulans follow suit, and by the early part of the 24th Century the Spore Drive has become a mainstay of interstellar travel in the Alpha and Beta Quadrants.
No longer limited by geography or travel time, Starfleet is able to jump to interesting-looking phenomena across the galaxy with ease, initiating dozens of first contacts decades ahead of schedule. On one unfortunate occasion, however, a Spore Drive ship jumps to the Delta Quadrant… right into the heart of Borg space. The Borg quickly assimilate the vessel, taking the Spore Drive technology for themselves and putting a target on the Federation’s back. Due to the distances involved, Starfleet remains unaware of what happened, merely recording the USS Discovery-C as “missing in action…”
Number 5: What if… Benjamin Sisko wasn’t the Emissary of the Prophets?

Ignore for a moment the revelation from Image in the Sand about Benjamin Sisko’s Prophet-induced conception! For this scenario, we’re considering that there were two occupants of the Runabout which first discovered the Bajoran Wormhole: Sisko and Jadzia Dax. Though the Prophets would choose Sisko as their Emissary, they could just as easily have chosen Dax instead.
Jadzia Dax returns from the wormhole having been anointed by the Prophets as their Emissary, and receives much respect and adoration from the Bajorans. Meanwhile, Sisko makes good on his threat and quits Starfleet, returning to Earth. Jadzia is promoted to the rank of commander and given “temporary” command of DS9, due in no small part to the way the Bajorans feel about her.

First contact with the Dominion occurs, and shortly afterwards the Dominion and Cardassians form an alliance – the work of Dukat, formerly the commander of Bajoran occupying forces on Bajor. The Dominion Cold War begins. Behind the scenes, Dukat is researching the Pah-wraiths, the ancient noncorporeal enemies of the Prophets. In disguise he travels to Deep Space Nine with a lone Pah-wraith, and in the course of unleashing the entity into the wormhole, kills Jadzia.
With no Emissary on the outside to come to their aid, the Prophets are fighting a losing battle against the Pah-wraiths while the Dominion War rages. The loss of Dax, though distressing to the crew of DS9 and her husband Worf, doesn’t appear to matter to the Federation war effort… not at first. In fact, the wormhole’s closure appears to provide the Federation alliance a reprieve, as the threat of Dominion reinforcements is reduced.

However, without the Orb of the Emissary re-opening the wormhole and expelling the Pah-wraiths, things go badly for the Prophets. When Dukat is able to implement the next phase of his plan and release the rest of the Pah-wraiths from the Fire Caves, there’s no one to stop him. The Pah-wraiths seize control of the wormhole, and as a thank you to Dukat they destroy the Federation minefield, allowing a massive fleet of Dominion reinforcements through the wormhole. The Dominion conquer DS9 and Bajor with ease.
With no way to stop Dominion reinforcements pouring in through the wormhole, the Federation alliance moves into attrition mode, trying to hold the existing front line for as long as possible against repeated Dominion attacks. Though the Pah-wraiths don’t actively take part in the fighting, their involvement allowed Dukat and the Dominion to swing the balance of the war back in their favour. By controlling Deep Space Nine and the wormhole, the Cardassian-Dominion alliance has the Quadrant’s most significant asset. It seems like only a matter of time until the Federation will have to sue for peace, if the Dominion would even accept…
So that’s it! Five Star Trek “what ifs!”

I can already think of more, so watch this space. I might return to this concept in future. I hope this was a bit of fun, and a chance to consider some alternative outcomes to some of the events we’ve seen across Star Trek’s history. I tried to pick a few different ideas from different productions – otherwise this could’ve been “five Captain Picard what ifs!”
As always, this was really just an excuse to spend a little more time in the Star Trek galaxy. It’s totally fine if you disagree with any of the storylines I’ve suggested today, or if you think this whole concept was a silly idea! None of this will ever make it to screen, and it was more of a thought experiment and creative writing project than anything else. I had fun putting this together – and I hope you enjoyed reading it.
