The Player Character. Because everything from his/her/it's appearance to species can be wildly different from player to player, only general characteristics will be listed here.
Ambadassador: You are a Starfleet officer, and that means you are supposed to be this in the absence of an actual diplomat. Beyond that, the diplomatic commendation system allows you (due to how it works, it's liable to happen sooner or later) to become an ambassador, complete with title and special uniform.
Ensign Newbie: Begins the game as a lowly ensign, who then takes command of their ship after the senior staff is killed by the Borg.
This has been slightly altered as of Season 8: The PC starts the game as a cadet who gets assigned as First Officer on their training cruise after graduation. Unfortunately, the Klingons ambush your ship, take the captain hostage who orders you to lock onto his comm-badge and blow away the KDF ship while it's cloaked and shields are down. Afterwards you try to rendezvous with another ship and right as this happens the Borg appears leading to the Vega portion of the tutorial. The fact you keep a crew of very scared cadets under control for the duration of the mission as well as rescue a large number of Vega colonists earns you a field promotion to Acting Captain.
Insane Admiral: For intents and purposes can be played as one and, well, kinda is one. They were recruited into Section 31 (with or without their consent, mind you) and typically treat Starfleet regulations pretty loosely.
Klingon Promotion: Ironically enough. Can be more appropriate if the player character is themselves a Klingon Starfleet officer purchased from the microtransaction store. Note that in this instance it's merely because they are killed, leaving you as an Unexpected Successor
Memetic Badass: In-Universe. The player returns from Vega colony to find word has already spread about them, and NPC's are increasingly starstruck by them as they climb the ranks as the game goes on.
Which becomes funny later in the game. You come back to Earth Spacedock as a Vice Admiral, after having blasted your way through Klingons, Devidians, Romulans, Remans, Undine, Jem'Hadar, Borg, Cardassians, and all sorts of other nasties, and the Starfleet NP Cs are still talking about the Vega System.
Red Shirt: You start the game as an ensign with no backstory, beamed onto a ship brimming with borg, and hopefully your not actually wearing a red shirt. Thankfully the trope is averted.
Season 8 changes that; you start out as an Academy trainee preparing for a career on Captain Taggart's command staff. However, before S8, if you were a Tactical captain, you'd literally start as a redshirt.
The Captain: Becomes this more and more over the course of the game, however...
Colonel Badass: ..They behave more like this, leading every away mission regardless of the importance or danger. Somewhat justified in that the Player is a particularly badass Starfleet Officer, regardless of career (and of course Kirk did the same).
Unusually Uninteresting Sight: Little is said by anyone about the PC having been given a full command from the rank of ensign. Until Shon expresses approval at their arrival for the Borg conference on Deep Space Nine, glad that someone else who has fought the Borg will be attending to explain the danger to the various diplomats.
The Player Character. Because everything from his/her/it's appearance to species can be wildly different from player to player, only general characteristics will be listed here.
Klingon Promotion: How else do you think you get your command, former second officer? Interestingly, it is actually a plot point that the KDF does have rules about this sort of thing — only the first officer can invoke Klingon Promotion on the captain, so because there is some uncertainty whether you actually had the right to do it (you had, though only by seconds), you get put to an additional test-by-combat on Qo'noS.
Pet the Dog: Almost literally. The KDF Captain "borrows" a Jackal Mastiff from Rura Penthe's pens to track down Franklin Drake. After the mission is over they keep the Mastiff as their own pet... that happens to be trained in combat.
Proud Warrior Race Guy: More Proud Warrior Adopted Culture Guy/Gal for some (Orion females aren't generally known for their warrior prowess), but other than that, general to KDF captains.
Space Pirates: A majority of your daily missions involve you attack civilian transport in your ship and take the spoils, while the duty officer mission "Marauding" allow you to assign your crew to capture ships / base and get items, commodities, and even prisoners. If you are using the Orion Slaver pets, you will also have a chance to take commodities or even currencies. To really get into it, you can wear an eye patch.
The Romulan Captain
The Player Character. Because everything from his/her/it's appearance to species can be wildly different from player to player, only general characteristics will be listed here.
Badass Pacifist: You start as this. You want nothing to do with the Romulan Civil War. Too bad Hakeev's a dick.
Call to Agriculture: Apparently, the destruction of Romulus is this to player, who chose to go with living a simple life on an unimportant colony world in the Neutral Zone as a farmer.
Of course, it can be subverted, as well. When you're talking to the person who tells the story of Virinat, you have the option of saying that you've been there since before all of that.
Deadpan Snarker: The available responses to the Romulan captain tend to have a little more bite to them than the others.
From Nobody to Nightmare: To the Tal Shiar. At the start of the Romulan campaign, you're considered little more than a nuisance. By the end, they consider you the single biggest threat to their reign, to the point that they send an entire fleet just to kill you.
"This is less than you deserve!" (shoots him in the head)
Neutral No Longer: The player starts neutral, as neither a member of the Romulan Star Empire nor the Romulan Republic. It's already confirmed they will join the Romulan Republic and NOT the Tal Shiar. This is because Hakeev and the Tal Shiar bomb the crap out of their home for fun. They also will choose to ally with the Federation or Klingon Empire in their war, though it seems to be more of political thing.
What Could Have Been: The Romulan PC was second choice for the Romulan flagship RRW Lleiset. Seriously. The player could have been the Romulan equivalent of Picard! They ultimately decided on the player keeping their ship so they're not bound to do the boring flagship stuff its mandated to do.
The Class of Starfleet Academy, 2409
"You never took that? And here I thought you were Mr. Extra Credit!"
The new Federation Tovan Khev character, the security chief for your training cruise upon graduating in 2409.
So Proud of You: So damn proud that he will call the player to come see them no matter what, be they in another universe, a parallel reality, or hundreds of years in the past, just to pat them on the back.
Big Good: For the "Romulan Mystery"/"Freedom" story arc.
Older than They Look: As a long-lived Vulcan, she unsurprisingly looks fairly young for a Starfleet Admiral.
OOC Is Serious Business: T'nae in the Romulan Player's arc is the Federation member who is opposed to a peace treaty. Though it's implied she thinks the Republic is no different than Sela's Tal Shiar. Still it makes her very three-dimensional and does kinda show some of the reasoning behind the Sundering.
Unfortunately, it doesn't exactly carry through to the Freedom arc, where (for Federation-aligned Romulans) she's your boss — she's ends up looking more petty than anything, due to unchanged dialogue having her repeatedly refer to Sela and the Tal Shiar's Star Empire as "the Romulans". Blame it on Cryptic being lazy and copypastaing the Fed missions onto everyone else starting with the Nimbus arc: The KDF missions are known to mistake you for Starfleet.
Turns out there is a LEGIT reason for this. T'nae's Blood Knight hatred for the Romulans? She was on one of the ships attacked by Nero when she was a young officer. After that you can't really blame her for having that. Source from Kestral's interview here: 
What Happened to the Mouse?: At the end of "Temporal Ambassador", the player character was beamed off the Enterprise-C to prevent polluting the timeline... except T'nae was still aboard when the Enterprise went back!
A Klingon Starfleet admiral and commanding officer of Omega Force, a joint Federation/Klingon task force formed specifically to battle the Borg and other forces that threaten the entire quadrant. Grandson of Worf.
Bling of War: Wears glitzy silver Klingon battle armor instead of a Starfleet uniform.
Half-Human Hybrid: Or 1/8 human, rather. He's the son of Worf's son Alexander Rozhenko by a Klingon woman.
Monster Munch: Not him, but his ship. The Houston is blown away by a Borg Unimatrix's lance weapon in "Hive Onslaught" pretty much just to show off the extra One-Hit Kill attack Cryptic gave them for the STF. He and most of his crew make it to the escape pods in time and are picked up after the battle.
Current CO of Deep Space 9 and the USS Defiant. Hands the player their missions during the "Cardassian Struggle" storyline.
Creator In-Joke/Self-Deprecation: Kurland is in charge of the station in the Bajoran system and is possibly a member of the Bajoran religion. Jeremy and his co-host Chris Fisher (who also had a one-shot guest spot as a Bajoran) are not fans of the Bajorans.
Big Damn Gunship: Comes to the player's aid in the Defiant twice. Once to aid the player against Klingons seeking to obliterate the Tribble homeworld again, and again in "Boldly They Rode" alongside the Enterprise-F.
Cool Starship: Kurland's secondary command, a Defiant-class starship, remains stationed at Deep Space 9 as she has been since the third season of the television series. Whether or not she is the same as the replacement Defiant introduced In the penultimate episode of Deep Space Nine is unknown, but previous to "The 2800" the Defiant was represented by a Valiant-class.
Failure Hero: Deep Space 9 is boarded and taken over no fewer than four times over the course of the Cardassian storyline.
The Exile: Briefly, during the Dominion featured series, courtesy of time-shifted Dominion ships occupying the station.
Give Me a Sword: Will not hesitate to pick up a phaser rifle and fight by the player's side when Deep Space 9 is boarded.
An officer serving aboard the USS Khitomer during the tutorial. Shortly afterward takes command of the USS Kirk, an Exeter-class starship.
Big Damn Heroes: Rescues the player from certain doom the first time they are attacked by an Undine Tethys Dreadnought.
Mauve Shirt: We know his name, we know he's Miral Paris' boss, and we're pretty sure he's still alive. That's about it.
Put on a Bus: Never seen again after the "Klingon War" storyline.
Lieutenant Miral Paris
Chief of Security aboard the USS Kirk. The adult daughter of Tom Paris and B'Elanna Torres, she was born aboard the starship Voyager as it returned to the Alpha Quadrant. Believed by some to be the Kuvah'magh, a messianic figure in Klingon lore.
Andorian captain of the USS Belfast and later the USS Enterprise-F. Becomes a constant presence in the game after meeting him towards the end of the Cardassian storyline, and occasionally fights alongside the player while patrolling the various systems of the Tau Dewa region.
All There in the Manual: The majority of Shon's exploits, and those of the Enterprise-F, are told in Star Trek Magazine.
Ace Pilot: In "Sphere Of Influence" his special tactical ability is Shon Evasive Maneuvers IV. Quadrupling the speed and turn rate of the ship you are piloting.
Cool Starship: The Belfast, a aging Defiant-class starship. And later the Odyssey-class starship Enterprise, NCC-1701-F.
Crusading Widower: His family was killed during the Borg attack on Vega colony that kicks off the Federation game.
Friend or Idol Decision: After the events of "Sphere of Influence", Shon is left with a major decision: Either he destroys the Iconian gateway in space to protect the universe and risk losing the Romulans' frienship or leave it alone and risk the Iconians or anyone else to charge through. the discovery of a Omega Molecule take the decision out of everyone's hands.
Proud Warrior Race Guy: Its easy to forget that the Andorians have this hat, but Shon does try to tone it down. Doesn't help the Enterprise gets the hard assignments.
Token Nonhuman: The first nonhuman to ever command an Enterprise (apart from Spock when it was assigned to Starfleet Academy at the start of Star Trek II: The Wrath of Khan). In-Universe, this appointment was taken by the Andorians as a sign that their species was returning to prominence in the Federation.
The captain of the USS Khitomer in the post-Season 8 Federation tutorial. Later gives Federation-aligned player characters the challenge to visit every sector of the galaxy in fifteen minutes.
The Alcoholic: Implied. Starfleet has apparently benched him and he now spends all his time in Club 47 aboard Earth Spacedock.
Ascended Extra: Previously he just hosted the "Tour The Galaxy" event mission. Now he's the CO of the USS Khitomer.
No Endor Holocaust: Originally the Khitomer's command crew was murdered by the Borg before you even got there. The revamped tutorial revealed Yim was the CO of the Khtimomer and the holocaust of the original tutorial never happened.
Guile Hero: Section 31 seems to have mellowed out a bit since the Dominion War, and Drake, for all his shadiness, is a tremendous help who's firmly on the side of the good guys.
Jerk with a Heart of Gold: Ever since the events of the previous century, Section 31 has had a deservedly poor reputation which Drake cheerfully embraces. Despite that, he takes care of his operatives and does little (if any) of the evil his organisation is infamous for.
Overt Operative. A variant. The circumstances always makes it clear that he's a spy, but he's remarkably open about the fact that he works for Section 31 (the intelligence agency that is so secret that almost no-one knows it exists) rather than Starfleet Intelligence proper.
Rugged Scar: Has a big ropy scar on his right cheek for apparently no other reason than that it looks threatening.
The former security chief of the USS Voyager, now a rear admiral and aiding in the Dyson Sphere alliance. He is also in command of Voyager now.
All There in the Manual: Only outside of universe sources have shown that Tuvok is the CO of Voyager. Of course this is also because Tuvok was featued in an episode where Voyager was absent for completely justifiable reasons. She'll be in later missions with Tuvok.
Bothering by the Book: His orders come from Joint Command, which means the orders were signed off by Starfleet, KDF High Command and the Romulan Republic. If you won't shut it down, he is under orders to do so.
But Thou Must: When you're told that the only way to stop the Dyson Sphere jump capabilities is to open up another Iconian gateway, you can flat out refuse. Tuvok will even tell you that if you don't open it, he will. If you continue being stubborn (and with good reason), he will activate the gateway.
Nice Job Breaking It, Hero: Thanks to being controlled by the Undine, he's allowed the creatures complete and total access to the Alpha Quadrant. He seeks to make it up through mediating a conference to solve the problem with the Dyson Sphere they recovered.
Recurring Character: The third canon Trek character to do so, and the second to promise to return.
What the Hell, Hero?: If you provoke the opposite faction flagship captain, refuse to shut down the station (and be forced to open the gateway) or try to take out the Voth without using the station defenses. The first time he will override you to prevent the situation from turning back into a shooting war with the Klingons/Federation (with the Republic getting split over it). The second time, his orders are to shut down the station from High Command, meaning he doesn't have to accept your orders on it. And the last one... well he'll do it since there is no rule in the book preventing it.
The Crew of the U.S.S. Enterprise (NCC-1701-F)
The new flagship of the Federation, replacing the Enterprise-E.
The first officer of the Enterprise under Captain Shon.
The Lancer: To Shon. Previously, he was one to Captain Akira Sulu.
Locked Out of the Loop: The guy sounds completely confused and frightened when he tells Captain Shon that the Enterprise is in a complete shut down and all the monitors are showing an Omega symbol, not knowing of the Omega Directive. Which is how things should be.
A Betazoid officer who helps co-ordinate the Starfleet Battle Group on Bajor. Right before the final battle of the Dominion Occupation of DS9, she transfers to the U.S.S. Enterprise to serve as their Chief Operations Officer.
Catchphrase: "I'm here to help."
Rookie Red Ranger: When the player meets her on Bajor she's only an ENSIGN. But apparently she does so well, it impresses Shon.
That little baby born in the last half of DS9 is now the head of the Enterprise's engineering department.
In-game as well. Yoshi was just a little continuity nod with a diplomacy mission on Memory Alpha. Now he's the Chief Engineer of the Enterprise.
All There in the Manual: Yoshi being on the Enterprise isn't ever discussed in-game. Even in the meet and greet with the Enterprise crew, he's absent (justified as they're meeting you during a major overhaul and repair). Finally corrected in "Sphere of Influence" where Worf asks Capt. Shon to give his regards to Yoshi.
Generation Xerox: Like his dad, he's an engineer (though Yoshi is an officer whereas Miles was an enlisted man). His father also served on an Enterprise. He's even called "Chief O'Brien" despite being a commissioned officer.
Military Brat: Son of a senior Starfleet NCO who happens to be the only major enlisted character in the canon.
Nostalgia Goggles: He has this about Jumja Sticks. In fact he gives the player a mission to bring a Jumja Stick from DS9 back to him simply so that he can taste home. Remember that Yoshi left DS9 when he was 3 years old.
Rookie Red Ranger: This is his first deep space assignment, having worked on Earth and Memory Alpha previously.
The KDF Captain's first officer.
Klingon Promotion: Promoted to first officer because he's the only person on the bridge left alive besides you.
Captain Ersatz: The Ferasans for the Kzinti due to copyright concerns. Tropes Are Not Bad as the Ferasans have had a chance to distance themselves a bit from their source material and become a unique race.
The Empire: For once, actually played with. The Klingon Empire is still an empire but the Federation influences have affected the government. The Gorn still have a measure of self-rule, the Ferasans are completely self-ruled but members of the Empire, and the Orions are allies by treaty. The Nausicaans and the Letheans are mostly mercenaries absorbed into or hired by the KDF following the Klingon-Gorn War.
Green-Skinned Space Babe: The Orions are allies of the Klingons and in fact have settled in KDF space (they were forced out of their homeworld by ecological collapse).
Heel-Face Turn/Face-Heel Turn: Due to the Undine infiltrations. Its a matter of perspective. The Klingon perspective is that the Federation invoked Head-in-the-Sand Management rather than confront the threat. To the Klingons' credit, they are proven right many, many times as much of the Federation story has them infiltrated by Undine, which doesn't occur on the KDF side.
The High Council actually entertained the Gorn Ambassador into discussing having a Gorn member of the High Council. Note that the Klingons get really xenophobic about having a vassal race be part of the ruling party, so even the entertaining of the Gorn's proposal is a big leap in philosophy.
The Gorn, Ferasans and Orions are vassal races now but they are not members of the jeghpu'wI' (conquered races). They're not citizens either but something between the two comparable to having a Klingon Green Card.
Reasonable Authority Figure: He believes Klingons are only Klingons when they are in combat, but after B'vat's death and the increase in Borg, Romulan, True Way and Dominion presence combined with the revelation of the Iconian incursion and increasing political pressure, he's backing off on the Federation Front and his forces are more working with Starfleet than trying to kill them. Subverted with his take with the New Romulans (see Pragmatic Villainy below).
Pet the Dog: He's very much in favor of good diplomatic relations with the Deferi. Even after it's revealed the Preserver Archive has no weapons data in it, he's still content to help the Deferi out of the kindess of his heart.
Pragmatic Villainy: His reasoning to help the Reman Resistance and the New Romulans? It's a way to conquer their greatest enemy, the Romulans, without firing a shot.
Rugged Scar: A nasty one running straight down the left side of his face.
What the Hell, Hero?: See most of the above. Even Worf thinks he's unhinged, and Martok's widow Lady Sirella has sworn vengeance against him. Any member of the House of Martok will kill him if they can find a reason besides plain old revenge to do so.
The former security chief of the USS Enterprise-D, then Strategic Operations Officer for Deep Space 9, and finally the Federation Ambassador to the Klingon Empire. Worf cut ties with the Federation following their refusal to deal with the Undine threat, but still has friends on the other side according to Franklin Drake.
Art Evolution: With Dorn's return to voicing the character (and giving Cryptic permission to use his likeness), Worf was given a revamped design to more accurately reflect a middle-aged Worf.
Badass: Worf is a formidable opponent now. Players have noticed that his tiny little disruptor compression pistol in "Sphere of Influence" regularly outdamages Mk XIIrifles.
A Klingon who adamantly opposes B'vat's insane plans. He defects to the Federation during the "Klingon War" story arc with information that B'vat is trying to sic a Doomsday Machine on Federation planets.
Ambadassador: In "Second Wave", S'taass starts literally ripping Jem'Hadar apart with his claws.
I Did What I Had to Do: During "Second Wave" we see him taking the "KDF is awesome" stance during the conference. Of course, he's WORKING so it makes sense that he's just saying the party line fed to him by J'mpok.
Knight in Sour Armor: Privately, S'taass doesn't like that the Gorn Hemegony has fallen to the KDF and off-duty he'll express how he wants to start a Gorn Rebellion.
Took a Level in Badass: When we knew him as Alexander Rozhenko, he was basically the IKS Rotarran's village idiot, a Non-Action Guy who had signed up to serve his country anyway and kept screwing up. He's come a long way since the Dominion War.
Torg, son of Kormog
Head of the House of Torg. He seeks to eliminate Worf and his House by collaborating with the Tal Shiar and ends up getting it discommendated for it.
Arc Villain: Tries to finish off the House of Martok. Thanks to the KDF player, it backfires.
Circle of Shame: When Torg's house is discommendated for his actions with the Tal Shiar, all the Klingons turn their backs on him.
Villainous Breakdown: After the aforementioned action, he flips out and tries to gut Worf. After you beat him down, he quickly makes an escape.
Ja'rod, son of Torg
The captain of the IKS Kang and head of the House of Duras. He's decided his family's history of dishonor must come to an end. He is the son of Lursa, one of the daughters of Duras who was killed by the Enterprise-D crew in Star Trek: Generations. He was adopted by Torg.
Ambadassador: It never comes up in-game but he is B'vat's attache.
Apologetic Attacker: To the House of Martok. He's opposed to them politically, but he does want to regain Ambassadors Worf and Alexander's respect. Unfortunately, this is Klingon politics, where that involves shooting or maiming each other.
Big Damn Heroes: In the Romulan Republic storyline mission "Devil's Choice", his IKS Kang is part of a joint Starfleet/KDF task force sent to help fight off the Elachi attack on New Romulus.
Blue Blood: Leader of the House of Duras and adoptive member of the House of Torg.
Goldfish Poop Gang: For the Federation player. Ja'rod is studying under Ambassador B'Vat and thus makes several early attempts to deal with the Federation captain. After being rescued from the Borg in "The Cure" he truly apologizes and declares them an honorable warrior.
Happily Adopted: Ja'rod likes Torg and was not pleased when the latter was discommendated. But he's an honorable man, and so he doesn't retaliate against the KDF player for their hand in Torg's dishonor.
Heel-Face Turn: For the House of Duras. Ja'rod, sick of his family's reputation, is working hard to turn the Duras family back into honorable Klingons. It's hilariously juxtaposed with his allies constantly betraying the Empire.
Heroic Blue Screen of Death: It's mentioned off-hand in "Spin the Wheel" that he's taken his adoptive father Torg's discommendation poorly. Soon after his other mentor B'vat is killed by the Federation PC and the revelations of "his evil plans" gets him put on Tribble Extermination Duty. He takes neither well.
Humble Hero: Very surprising for a leader of the House of Duras. He was even offered a seat on the High Council after several sucessful missions only to turn them down as he felt he wasn't worthy of the title yet.
Ja'rod: Until I have fully proven my worth to the Empire, I do not deserve to be in your number. I will return to Qo'noS as a hero, or not at all.
Klingon Promotion: About fifteen years before the start of the game, his captain refused to investigate the Undine attack on him, so Ja'rod led the crew of the Kang in mutiny and killed Captain Klor and his first officer.
Only Sane Man: The first member of the House of Duras we've ever met in the entire franchise who isn't determined to overthrow the Empire's leadership. It helps that J'mpok is a political ally, but he seems to want to be a loyal Klingon citizen regardless of whose commands he obeys.
The Worf Effect: He's credited with the first Undine capture since their return. Every time you meet him in game, you kick his ass or bail him out.
A guard from the House of Torg assigned to Rura Penthe.
Either that or he is a random Klingon that just happens to share a name with Kurn's new identity. If he is Kurn, there's an interesting story unexplained for how he went from Rodek, 'son of Noggra' of the House of Noggra to Rodek, guard in the House of Torg.
The first officer of the KDF player's Bird-of-Prey at the start of the Klingon tutorial. Dies in the first fifteen minutes when she unsuccessfully challenges Captain Jurlek for betraying the Empire by trying to hand a Federation prisoner-of-war over to the USS Musashi.
The captain of the KDF player's Bird-of-Prey during the Klingon tutorial. The player kills him for committing treason against the Empire in trying to hand a Federation prisoner (Franklin Drake) back to Starfleet.
Dirty Coward: He's shown to be very fearful of having Franklin Drake onboard his ship and conspired with the crew of the Galaxy-class USS Musashi to take him back. He planned to go on to many more battles to restore his honor after that.
Heel Face Door Slam: The aforementioned plan? Gets derailed after you confront him and invoke a Klingon Promotion on his ass. He's quite displeased at that when you encounter him in Gre'thor.
My Greatest Second Chance: The KDF Player allows him to help in their storming the gates of Gre'thor, though the player notes that even this might not be enough to send his soul to Sto'vo'kor. Apparently, it is.
Dude, Where's My Respect?: She absolutely freaks out after the Romulan Republic declares that the Jenolan Dyson Sphere is theirs, tired of the Federation and the Romulan Republic getting all the cool toys and the Klingon Empire getting left in the dust.
I Am X, Son of Y: Introduces herself in "Sphere of Influence" as Koren, daughter of Grilka.
You Go Girl: The general reaction whenever she shows up.
The Romulan PC's best friend from Virimat and their first officer.
Blue Blood: His father was a noble and leader in the Romulan Star Navy prior to the Hobus incident. Tovan was 8 and off-world with his mom and sister when the supernova happened and his father was killed on Romulus. Tovan is now just a security guy on Virinat.
Dangerously Genre Savvy: When he meets you he knows you're a spy. If you manage to talk him down, he admits that you're a determined enemy and a potentially dangerous one. When you escape he simply asks for your help because he knows you're the best chance for it. The end result? The collapse of the Tal Shiar, the kidnapping of Empress Sela by the Iconians, and the founding of New Romulus with the Romulans.
Heel-Face Turn: Regardless of storyline, when you first meet him he's an antagonist raiding the Vault, and his ships attack you because he isn't convinced that your faction can be trusted to help free his people. After you locate him and meet him in person, he brings the Reman Resistance over to your side.
Years prior to the destruction of Romulus, the Tal Shiar were the Romulan Empire's intelligence agency, working behind the scenes to protect the Empire. With the planet's destruction and the Empire's shaky foundation, the Tal Shiar has now become its own organization, trying to restore the Empire by force, utilizing means that even the current Empress, Sela, would disapprove of.
Brainwashed and Crazy: It's implied that a lot of the Tal Shiar's members have been mucked around with, especially with Hakeev around.
From Nobody to Nightmare: From intelligence agency to a force to be reckoned with. They were always a feared intelligence agency both outside and inside the Romulan Star Empire, but now they are running around with more warships than the actual Romulan Navy and more-or-less ruling what's left of the Empire.
Man Behind the Man: Sela's nothing more than a puppet to them. Except not really. She isn't that friendly to them, is indicated to run some schemes to counter theirs, and promptly abandons them the moment they are no longer of use in propping up her rule. The problem is that she gets kidnapped by the Iconians immediately afterwards.
Big Bad: Of the "Cloaked Intentions" featured episode series and the "From the Ashes" introductory mission series for the Romulans.
Chronic Backstabbing Disorder: According to Taris — Hakeev was her science officer, and said that there was no risk messing with Iconian technology. She says she didn't know the device she was activating would cause the Hobus detonation. She thinks he did. A mission later, it's clear that Hakeev is going behind Sela's back as well to at least some degree.
Cool Starship: In Legacy of Romulus, his flagship is the I.R.W. Knial, a D'derdrix-class Warbird. After the tutorial and Hakeev's implantation with Borg tech, he starts adding on more borg gear on to the ship. Eventually, he takes it past the player's use of Borg Tech (which is simple modification and addition) to transform the Knial into a Narada-classDreadnought.
Cybernetics Eat Your Soul: After the Romulan PC injuries him at Virinat, Hakeev's left eye is replaced with a Borg Cybernetic implant. Granted, he had no soul before either...
The Heavy: Of the Romulan Myth Arc. There are other villains, some more powerful and influential than him, but he's by far the most central, visible, and plot-important.
Sanity Slippage: By the time of the Cloaked Intentions FE series on the Romulan side, Hakeev clearly is devolving into this.
Screw This, I'm Outta Here!: You lure Hakeev to Nimbus III with a fake note about the thalaron triggers. He's more than happy to crush you right then and there, but when the Nimbosian Pirates show up to settle a few more scores, Hakeev quickly gets cold feet and cloaks away.
The Empress of the Romulan Star Empire and the half-human daughter of the temporally displaced Starfleet officer Natasha Yar.
Art Evolution: Sela originally had an old blonde lady Romulan's model in her first appearance. They got away with it because Sela was only seen once in a low resolution pop-up window. When Denise Crosby returned to the role, she was revamped to look closer to Denise in the 80s.
Enemy Mine: The only reason she's working with the Tal Shiar is because they are the most organized remnant of the Romulan Star Empire and keeps her afloat. It becomes clear at the end of Cutting the Cord that she has no respect for the Tal Shiar and with Hakeev's utter failure, she leaves them to fall apart.
Reasonable Authority Figure: Shockingly, an actual villainous example of this. She places a great emphasis on loyalty to the Empire and to the values of the Romulan people. She even admits that her doings with the Tal Shiar are extreme, but that she's only doing it to reunite their people. The problem is that Hakeev and the Tal Shiar are working behind her back (its pointed out at one point Hakeev has stuff that Sela wouldn't even approve of him just having as a memento) and working for the Iconians, meaning the values she holds dear aren't valued by her allies and are the very values the Romulan Republic represent.
"The Reason You Suck" Speech: Gives one to Hakeev in the Legacy of Romulus version of Cutting the Cord, calling him out on his BS and that his plan has only pissed off the Iconians and left one of their major bases now under attack while the leader of the Empire was meeting with him.
Hakeev: We only need to wait! The Iconians are coming and when they get here, victory will be ours! Sela:(incredulously) You call this Victory!? Hakeev: When the Iconians get here— Sela: That was Taris' plan too! Look where that got her. This is done! YOU'RE DONE!" (beams out) Hakeev:No, wait! I--
Unwitting Pawn: To Hakeev and the Iconians and possibly the Elachi as well.
What Happened to the Mouse?: She is kidnapped by the Iconians at Brea III. "Sphere of Influence" hints that they're trying to get her to see things their way to get the Romulans under their control.
The leader of Ambassador Spock's reunification movement. Following the disappearance of Sela, he sets up the colony of New Romulus with the Reman Resistance and is now the Proconsul of the Romulan Republic.
The Atoner: He pretty much takes this role on behalf of his people, wanting to make up for the bad blood between his people and the Federation & Klingons in the past and start over anew.
A Romulan Researcher who discovered an Iconian gateway tucked underneath New Romulus' main city.
Not Himself: When you first meet A'Dranna, she's completely out of it, virtually distracted. This is because the Iconians secretly kidnapped her and mucked around with her mind.
The Complainer Is Always Wrong: She invokes this on Captain Shon when he suggests destroying the Iconian gateway near Jouret IV. She even goes so far as to threaten having D'Tan reconsider the Federation's friendship with the Republic if they do so.
The Former head of the Romulan Star Empire before she went "missing" in the years before Sela's rise to power. She is also responsible for the destruction of Romulus but she claims she was tricked by Hakeev.
Big Bad: For the first Federation Romulan Story Arc. However, Romulan players get a different insight into her and learn she may have been tricked by Hakeev.
Spanner in the Works: She's responsible for the 2009 Trek Movie, Nero, Sela's rise to power and D'Tan's Romulan Republic. All things that would not have occured if not for the Hobus Supernova. The Romulan Faction storyline has her trying to get the Iconians to pull a Heel-Face Turn. Considering the Iconians are behind everything well see if she is successful.
Heroic Sacrifice: Temer uses his personal shield to protect the Klingon Ambassador at the Khitomer Conference. In doing so, he singlehandedly redeems the Romulans in the eyes of the Klingons, showing that they have bravery and honor.
A Tal Shiar operative and Tovan's former lover. She approaches the Romulan Captain shortly after their promotion to Centurion and tries to convince them that D'Tan's goals may not be as noble as he says they are.
Redemption Rejection: After you save Charva from the Tal Shiar, she's utterly adamant that you didn't save her from the constantly turncoat Tal Shiar, but that you purposely mislead her so she could be taken in by D'Tan's "terrorist movement".
Cool Starship: She commands a Falchion-class dreadnought warbird. And its the Romulan Flagship.
Fan Nickname: Before her debut she was plastered all over the Legacy of Romulus posters as a hot Romulan. She was immediately named So'Hott by the fans.
A Reman with a very big habit of being in the wrong place at the wrong time.
Chronic Backstabbing Disorder: In the Romulan storyline, it's hinted that he's the reason one of the Reman colonies was taken captive by sabotaging a communications dish. He does it again in "Colosseum" when he lures you to his ship and ends up bringing you to Hakeev.
Joint Task Forces / Reputation Groups
Max Level characters can start to partake in reputations with several organizations in regards to certain combat. These Joint Task Forces usually involve going up against enemies of all three factions, even if those factions are not allied with each other.
A joint task force created by Admiral D'Valk in the interest of Federation and Klingon protection against the Borg. The Federation half of the task force is run by Military Assault Command Operations (M.A.C.O.) and the Klingon half is run by the Klingon Honor Guard.Headquarters: Starbase Deep Space Nine and Battle Group Omega
Enemy Mine: Federation and KDF interests who started this group agreed that working together was more likely to stop the Borg. The Romulans joined later.
A joint task force dedicated to the construction and protection of New Romulus. Unlike the other reputations, this task force is more dedicated to science and humanitarian efforts and ultimately responsible for the storyline developments of Season 8.Headquarters: New Romulus
Enemy Mine: Chancellor J'Mpok sees helping the Republic as a way of conquering the Romulans without needing to use force. They've since proven to be valuable allies.
For Science!: The theme of the non-combat missions. Eventually it leads to study of Iconian Gateway tech including an intact gateway and them building a space gate for the Dyson Sphere in Season 8.
Took a Level in Badass: Ultimately, the NR Rep leads to the Romulans gaining Iconian Technology and surging to becoming a superpower again. Shame the Iconians sabotaged the whole thing...
A Joint Task Force dedicated to stopping Tholian Incursions in local space, starting with Nukara Prime. Notable in that while the KDF and Federation are fighting Tholians on Nukara Prime, both forces are working independently and only tolerating each others' presence.Headquarters: Nukara Prime
Enemy Mine: Again, the KDF and Feds aren't technically working together on this project. They're merely serving their own interests together. That interest happens to be throwing the Tholians out of their (contested) space.
Dyson Joint Command
A Romulan Republic led Joint Task Force dedicated to throwing the Voth out of the Solanae Dyson Sphere and the securing of the Omega Molecules within.
Enemy Mine: For the Klingons and Federation, seeing as they are still at war back home in the Alpha and Beta quadrants. The Romulan Republic takes the lead, which helps the Dyson Joint Command work out as a formal alliance (Omega Taskforce works partly because one of the main driving forces behind it is a high-ranking Starfleet officer with ties to important persons in the Klingon Empire, and Nukara Strikeforce technically is just a local ceasefire).
This is exemplified by the end of "A Step Between Stars" as players discover the other Sphere and, automatically, both Romulans and Klingons seek to claim it as their own.
Non-Player Faction Characters
A race who believe in balance with the forces of nature and advancement.
Martial Pacifist: They only fight for survival. Their only enemies are the Breen (who kidnap them as slaves and steal their crap) and the Borg (who are everyone's enemy).
Morality Pet: To J'Mpok's Klingon Empire, who view them as very honorable for saving a Klingon Fleet decades ago. The Klingons don't even want to conquer them.
The lead ambassador for the Deferi to offworld cultures.
Ambadassador: Subverted, he doesn't want to fight anyone. At the Borg conference he states that the Deferi will remain neutral if a consensus can't be reached.
A mysterious Romulan who aids your player during the initial stay in Nimbus III
Broken Ace: Was once a proud lawman, but after being betrayed by a number of people and being abandoned, he's turned into a bitter man. At least until you show up.
Dead Man Writing: Subverted. He writes a letter to the player character when he decides to take care of a spying Gorn, fully expecting to die... only to come back and sheepishly shrug at the player when he's safe and sound. He's clearly embarrassed the player found the letter and found out he's safe.
Hassan the Undying
Chief enforcer of the Orion Syndicate, he holds Nimbus III in a death grip, as well as allowing the Tal Shiar to do what they wish.
Screw This, I'm Outta Here!: When your player character defeats all of his gladiators and himself, he gets fed up, teleports away and sics everyone in his building on you.
Smug Snake: Certainly this prior to breaking him. He's incredibly secure in his power and isn't afraid of making sure you and anyone else is put in their place.
Stout Strength: He's surprisingly portly for Melani D'ian's most feared assassin.
Villainous Breakdown: After you best him in combat, he panics and runs away. When you chase him into space, he's ranting and raving that you'll never take him and that he and the Orion Syndicate will keep Nimbus III.
The Nimbosian Pirates
A group of various races that take pleasure in robbing people and have a major chip on their shoulder towards the Orion Syndicate.
Big Damn Heroes: In "Installation 18", they show up as soon as Hakeev and his men arrive to take you on. Hakeev takes the moment to skedaddle out of there.
It's Personal: They all hate the Orion Syndicate (or at the very least Hassan) and are willing to give you a hand if you fix up a problem they have with their ship.
One of Us: One of the items you can earn by beating the mission "Installation 18" is the Nimbus Pirate Distress Call, which brings the pirates to you. This is what happens when you save their bacon.
Lieutenant Natasha Yar
Played by Denise Crosby
The Alternate Yar from the Enterprise-D from Yesterday's Enterprise who went back in time with the Enterprise-C. ... Except they went the wrong way. Woops!
A mysterious race who's only previous appearance in canon was as an unnamed ship that faced down Captain Johnathan Archer.
Bigger Bad: To the Tal Shiar. They are the Iconians' agents in the Alpha and Beta Quadrants and thus more the Mid-Level Bad.
Cybernetics Eat Your Soul: Some Elachi have cybernetic implants that are very Borg in design. As Iconian allies, its probably some of Hakeev's borg tech modified with Iconian Technology.
Happiness in Slavery: As a result of the implants ...or not since the Dewans volunteered to become the Elachi.
Death Before Dishonor: The first Elachi confronted by the protagonists commits suicide rather than answer any of their questions and without even saying anything.
Shout-Out: They look like ET when unmodified with cybernetics. This is the indication that they are the Dewans (who share the exact same appearance.
The Reveal: We see their appearance in the Nimbus arc's finale. You need to get to Tier 5 Reputation on New Romulus to unlock the recording of the Iconian Gate between the Iconians and Dewans to know that the Dewans are the Elachi.
The Unseen: For most of the Romulan Arc and the first seven seasons of STO.
Tragic Villain: They're not natives of Subspace. They used to be just like us. Until the accident occurred. They were only to help the Iconians build the Solanae Dyson's Sphere as far as we know. Now serving the Iconians is the only link back to their old lives.
A conquering species that existed over 200,000 years ago, they were presumably wiped out when the races they ruled finally revolted and got rid of them. That is not the case. At all.
Troll: To the Borg Collective. Considering they used an Omega particle to lure a Borg Cube in Sleepers only to gate out their central plexus when they began to experiment. The Iconians don't need to lure them to do that as they can easily destroy or disable the cube, the only answer left is For the Lulz. Especially since the Iconians have known the Borg for god knows how long (their species number is the lowest known at 47) and have never once been assimilated by them.
The Voth (as a group)
A race of lizard-like humanoid creatures said to have evolved from dinosaurs that live in the Delta Quadrant. They seek to control the Solanae Dyson Sphere and the Omega Particles within because of the Doctrine.
Freudian Excuse: The reason why they're not helping us? Because we're there. Oh, and they're still sore about their encounter with the Voyager.
Internal Retcon: By this point, the higher ups sure as hell know that they're not the first species and they're doing their damnedest to keep their version of the truth as the truth. One Voth scientist has realized that this is going to destroy everyone because of the Iconians.
Mecha-Mooks: Oh, plenty of them. They usually attack in packs of three and are armed with plenty of antiproton weaponry.
No Sell: Their ships have a special barrier that protects them from all weaponry. Even worse, they can reflect it right back at you.
Too Dumb to Live: The Tier 4 Dyson cutscene is proving more and more that they have absolutely no idea what they're doing with the Omega particles and those like Nelan below realize that they're heading towards something dangerous.
That something dangerous? They want to use Omega Particles to obliterate subspace for the express purpose to defeating whoever they're fighting! They don't care if they're forever isolated or worse, isolating other races - they've entered a Suicidal Cosmic Temper Tantrum and they're taking everyone with them just to have their victory.
The Worf Effect: To show that the Undine are back in full force, a Voth Dreadnought, which usually takes an entire team of players to shoot down, is shot out of the sky unceremoniously in one shot.
A Voth scientist who contacts the player to send intel while trying to get his people to accept the truth.
What the Hell, Hero?: Gives this to the Ministry of Elders on a regular basis. They don't believe him and are trying to suppress his research.
Though the early-tier videos give the impression that he doesn't do it, but would like to do it if it wasn't for the fact that he's seen what happens to people who veer too close to arguing against the Elders' interpretation of Doctrine.
Screw This, I'm Outta Here!: In the Tier V cutscene, he has had enough: the Voth have absolutely lost it and he refuses to do anything else with it.
Sixth Ranger: He joins your team as a Science Bridge Officer.
