Entering the Star Trek world as an unnamed extra with a few bits of dialogue, O’Brien soon became a fixture on the Enterprise D as it’s transporter chief before moving to Deep Space Nine to head up engineering and operations on what was thought to be a backwater outpost before it became one of the most strategically important stations in the quadrant!
As the only enlisted or non commissioned officer to feature in the main cast of any Star Trek show to date, O’Brien stands as the only working class hero in the Star Trek universe with a vast and varied career taking from the front lines of the Cardassian war as a soldier, to the front lines of the Dominion War as an engineer, retrofitting DS9, keeping the Defiant from blowing itself apart, and even sniping Dominion troops. All in a days work for the Chief!
In honour of his efforts and inspiration behind our newly re-crafted enlisted ranks, we thought it well overdue to say Hail to the Chief with five of O’Briens best episodes!
EMPOK NOR
DS9 Season 5 Episode 24
One of the highlights of O’Briens run in Deep Space Nine takes place on a mirror of DS9, a decommissioned station being scavenged for spare parts with his cadet sidekick Nog, and Garak as the tour guide. But Empok Nor wasn’t just decommissioned, it was quarantined and their arrival unleashed a psychotropic virus and the Cardassian carriers left behind…
As Garak becomes infected with the virus, and in turn begins hunting O’Briens team, the Chief has to find a way to stop a highly motivated trainer killer and get himself, and his team, out alive. Empok Nor is a fascinatingly dark departure form Deep Space Nine’s usual themes and presents a dark thriller that see’s O’Brien taunted about his past as a soldier as his teams slowly hunted down and killed one by one.
TRIBUNAL
DS9 Season 2 Episode 25
Following an arrest by the Cardassians, O’Brien finds himself on trial for a crime he didn’t commit. But that doesn’t really matter as in the Cardassian justice system, the verdict comes first and the trials just for show…
Sharing the spotlight with Odo in a unique coupling, the Constable has to find out what’s behind O’Briens tale of woe and try and fight against a legal system that’s fixed by default. Turns out O’Briens past came back to him after bumping into a former shipmate from his days during the Cardassian conflict, but it wasn’t a chance encounter after all…
THE WOUNDED
TNG Season 4 Episode 12
The first real story about O’Brien and a prelude of what was to come in Deep Space Nine, the Wounded is also the first appearance of the Cardassians. After being attacked by a Starfleet ship, Gul Macet leads a retaliatory attack on the Enterprise. A confused Picard promises it’s all a weird misunderstanding and learns a rogue Captain is on the cusp of reigniting a recent war.
O’Brien, largely a background character up until now, served with that Captain during the Cardassian conflict and is brought out of the lower decks as the expert on his former boss. But after fighting in the war, and recounting the brutality of a conflict on Setlek III, O’Brien struggles to put his own prejudice and memories of the fight behind him…
WHISPERS
DS9 Season 2 Episode 14
Growing suspicious of everyone around him, O’Brien tells the story of how he ran away from Deep Space Nine. Recounting the story from a stolen runabout, O’Brien recaps how in recent weeks things has been peculiar. His crewmates seemed distrustful of him, but it went beyond odd behavious at work. His wife was acting strangely too…
Suspecting everyone had been brainwashed, he ran. But things weren’t as they seemed. On a trip to Parada, O’Brien had been replicated in a plot to use the replication in a political move against the planets rebels. Playing on the idea of a conspiracy on the station, it turns out the replica just didn’t realise he was the fake all along…
HARD TIME
DS9 Season 4 Episode 19
With the amount of times O’Brien was put in bad scenario’s as he was the most down to earth and easiest to connect with, it became a bit of an in joke. O’Brien must suffer. There were few moments as harsh and as painful to watch than seeing him suffer through Hard Time.
Charged and sentenced on an alien world where prison is a memory implant rather than actual incarceration, in a matter of hours O’Brien lived in solitude for decades. It’s an efficient idea as well as it was effective. You get all the punishment of a life sentence without the cost or resource and it’s not just a simple memory implant, the time and experience lives with you and when O’Brien woke up, all that prison time was as real as anything he’d ever experienced.
Struggling to adjust to a normal life and that no time has really passed at all, there’s a lot of tension a both at home and at work as he tries to figure out how to be an engineer again and struggles to cope with balancing the trauma of decades of isolation and suddenly being back in the middle of a happy marriage again. But as his frustration turned to aggression, he had to face the reality of his time in mind prison. He wasn’t in isolation. He had a cell mate. Through periods of being starved and abused, malnourishment turned to paranoia and after decades of having no one but each other, O’Brien killed his only friend in a scuffle over food.
Riddled with shame and guilt, O’Brien wasn’t just adjusting to life after prison, but to the fact that he’d murdered a man over nothing. Coming to a head, it took his space bestie Julian to talk him down when the guilt became too much to bear and O’Brien tried to end his own life showing us just how past breaking point O’Brien had come and how much of a lasting impact his sentence would have on him.

Warped: ‘Off Hour’, Strange New Worlds S4E06
Towards the end of a long and tiring shift, the command team are more than ready to hand over to the night shift. But no one makes it far from their station as at the moment of handover, the Enterprise gets pulled into a warp slipstream that knocks out the ship and traps them in an escalating and catastrophic acceleration taking the ship well beyond its limts. Writers: Bill Wikoff Director: Dan Liu Strange New Worlds is an interesting creative, narratively speaking. When they swing for the fences in their creative mission, it's very hit or miss. But when they keep things simple and focused on character work, they really shine. And this weeks was one that kept it simple with a tried and tested format that always works nicely; have the ship suffer a critical accident, cut everything […]

A Fistful of Down To Earth Adventures
Warping through the stars always searching for the next adventure, it's rare that Star Trek ever comes home to Earth. Through all the series, and highlighted in Enterprise, the third rock from our sun is kinda important in the grand scheme of things but our eyes are always far beyond the stars. So for no particular reason at all - certainly not any recent new series launching - we're taking a look at Trek's more Earthbound moments.... Homefront/Paradise Lost Deep Space Nine Season 4 The Founders said they were everywhere. Now we know they're on Earth. Recordings revealed a founder during the bombing of a Federation meeting on the home-world and Sisko is recalled. His knowledge and experience with the Dominion is vital to securing Earth against the inevitable war. But while the Dominion may be the enemy, they aren't […]

A Fistful of ‘Spirk’
We've been spoiled with Spock in the past few years with Discovery introducing a younger iteration of the character long before he became the refined man of logic that made him famous, and continued that story through Strange New Worlds and his time under Captain Pike's command. As Strange New Worlds continues, giving more history to the original series line up and the early meetings of Spock and Kirk as it makes way for the beginning of the Kirk era, we thought we'd look back at some moments that made the partnership one of the most popular combinations in science fiction. JOURNEY TO BABEL TOS Season 2 Spock's got a bit of an issue with sharing. Secret brother who was shunned. Secret sister who's fate was classified. And despite trusting the Enterprise crew with his life, it was clearly only […]

A Fistful of Justice
Although it's one of the worlds most legendary science fiction shows, Star Trek has always dabbled with format and genre's, all dressed up behind deep space adventures. Whether using the holodeck for a touch of fantasy, or diving into the horrors of war through Deep Space Nine's run, the variety of story telling never seems to fit one mould. But out of all the different tales told in the wonderful world of Starfleet, one that always promises to deliver is the court room drama. This month we're diving into the most captivating of Star Trek's courtroom drama's with a Fistful of Justice! AD ASTRA PER ASPERA Strange New Worlds, Season 2 One of the most modern examples of Strar Trek's court room drama saw Pike's own Number One, Una-Chin Reilly, under court martial for a serious breach of Starfleet regulation […]

A Fistful of Sisko
In the past few years, Star Trek has made several nods to it's past. But while The NExt Generation and Voyager had their continuations, Deep Space Nine continued to 'black sheep' of the family with it's history and name drops being few and far between. Until Academy when we had an entire episode based around the legend of Starfleet's most complex captains. Starting his show as a widower and single parent, Benjamin Sisko started his time in Star Trek as a reluctant hero turned religious icon who's become a prime figure in Bajoran history, the Federation-Dominion war and much more. If you missed his series, first of.... why?! And also, if you want a quick intro - here's our Sisko top five to see what the fuss is all about. https://www.youtube.com/watch?v=SzBkvzPoofQ IN THE PALE MOONLIGHT Season 6, Episode 13 Lets […]

A Fistful of Honour Beyond Bloodshed
Feared throughout the galaxy due to being fearless warriors who thrive on battle and bloodshed, the Klingon's are one of Star Trek's most iconic races and yet, with all their history, perhaps the most misunderstood. Starting off in the original series as authoritarian and distrustful antagonist, they were written as a parallel to Russia with the Klingon Empire in a cold war with the Federation following a long conflict. The Klingons would have a bit of reinvention in the movies thanks to higher budgets giving the producers a chance for a more alien look, while their culture and history would get a little more depth on The Next Generation thanks to the inclusion of Worf, the first Klingon member of Starfleet. But Worf's views on the Klingon culture weren't quite spot on. From a noble house, Worf was displaced and […]
