Enterprise Crew

Ens. Fouton

A humanoid alien of an unidentified race, and visually distinguished by his talk, lanky frame, white mohawk, and large, compound pink eyes. Fouton was an enthusiastic new member of Enterprise's security team, accomplishing both of his career goals: becoming a Starfleet security officer, and serving under Captain Kirk. His species takes loyalty to one's superior officers to levels of almost fanatical devotion, and Fouton was no different. When it appeared that Kirk would turn himself over to Prefect Witten, who desired the bounty on his head, in exchange for Witten to give McCoy time to find a cure to the disease ravaging New Brinden, Fouton took it upon himself to protect Kirk by infecting Witten with a sample of the disease.

• Animal Eyes: One of his most dominant features.
• '80s Hair: His hair is worn in a positively towering white mohawk.
• Gadgeteer Genius: He actually does invent a vest completely impervious to phaser fire. Unfortunately, only the vest is impervious. It's also impossible for a human to actually wear.
• Genius Bruiser: Far more thoughtful than one would expect for a department that's typically relegated to Red Shirt status. He invents a phaser-proof vest (it...has bugs), and when during a sparring match Chekov orders him to pretend that he (Chekov) is a Klingon, his first thought is to analyze the threat level by inquiring which Klingon.
• Hero Worship: He considers the opportunity to serve Kirk the highest honor. In fact his species takes this to the point of fanaticism: They protect their leaders at all costs, and think nothing of laying down their lives for them. In fact despite being stripped of his rank and court-martialed, Fouton tells Kirk and Nogura that regardless of what Starfleet thinks of his actions, when he returns home he'll be celebrated for the sacrifice he made to protect his commanding officer.
• Hypnotic Gaze: Fouton is able to hypnotize other beings, and used it to force Tuchinsky to beam him down to New Brinden for his attack on Prefect Witten.
• It Has Been an Honor: Tells Kirk that serving under his command was this when he's being led away after being court-martialed. That this devotion to their superiors is practically his species' Hat is pretty much all that's known about their culture.
• Moment Killer: Interrupts Kirk and R.J. Blaise to confess to his role in infecting Prefect Witten, just as R.J. is getting ready to confess her feelings to Kirk.
• Muscles Are Meaningless: While he's incredibly tall, his frame is almost comically thin. Yet he can still floor Chekov with a single kick to the head during a sparing match.

Ens. Thomas Lee

A rookie Enterprise security officer, fresh from the academy. He's eager to serve and make a good impression on his captain, but is killed on his first away mission saving Kirk's life in an ambush.

• Heroic Sacrifice: Dives between Kirk and a pirate captain, taking a fatal disruptor blast at close range, but saving his life in the process.
• Red Shirt: Lee is a deconstruction. The plot of issue 19 centers around the crew's response to the death of one of their own, and the realization that nobody really new him.
• We Hardly Knew Ye: Played With in that it's actually a plot point; the entire issue centers on how no one really knew anything about him.

Lt. jg. Kathy Li

A navigator and helmsman aboard Enterprise. Lt. Li shared a mutual attraction with Sulu, leading to her butting heads with Lt. M'yra.

• Put on a Bus: Requests a transfer to Starfleet Headquarters after a dressing-down by Sulu over her and M'yra's fight for his affections. Both she and M'yra depart by issue 12.

Lt. jg. M'yra

A lower-ranking officer aboard Enterprise, who developed an attraction to Sulu. This put her at odds with Lt. Li, who was establishing a fledgling relationship with him, and led to her taking an...aggressive stance against her rival for his affections. She also learned to play chess from Spock.

• Fiery Redhead: Her hair is bright orange, and she can be very hot-tempered and aggressive towards her rivals.
• Horned Humanoid: Has two prominent, goat-like horns, lending her a demonic appearance. Much like actual goats, M'yra's species apparently uses them for dominance displays, as she remarks to Sulu that her people are literally built for head-butting to explain her Tsundere tendencies.
• Hot as Hell: She looks the part, being a very attractive, but demonic-looking woman with the hots for Sulu.
• Prehensile Tail: Another of her prominent, devil-like features is her spade-tipped tail. It's flexible and dexterous enough for her to move chess pieces around the board.
• Put on a Bus: She accepts a posting aboard USS Einstein after a dressing-down by Sulu over her rivalry with Lt. Li for his affections. She and Li are both out of the book by issue 12.
• Smart People Play Chess: Her introduction is a chess match between her and Spock. Although she does lose, Spock's remarks suggest that she nonetheless provided him a challenge.
• Tsundere: She's very sweet and demure towards Sulu, but when confronted with a rival for his affections she becomes much more aggressive.

Lt. jg. Nina Popov, M.D.

Chekov's younger cousin, whom he used to babysit. She joined the crew of Enterprise on an internship in time for their mission to investigate Romulan activities around Pilkor III. Much to Chekov's consternation she struck up a brief relationship with Sulu.

• Funetik Aksent: The same as Chekov's.
• Hospital Hottie: A doctor and recent graduate of Starfleet Academy. Sulu is immediately smitten with her.
• I Am Not Pretty: Chekov teases her about being so focused on her education that she didn't have a boyfriend while growing up. Nina self-consciously responds she can't believe anyone would want an "ugly duckling" like her, despite the fact she's clearly quite a beautiful woman, whom Sulu was instantly attracted to.
• Papa Wolf: Chekov becomes one to her when she begins dating Sulu.
• Parental Marriage Veto: Chekov tries to invoke this when Nina gets closer to Sulu.
• Put on a Bus: Accepts a posting aboard another ship following the completion of the Pilkor mission.

Lt. Sara Tuchinsky

Enterprise's transporter chief, and a member of Mr. Scott's engineering staff. Tuchinsky is notably the only character created specifically for the comic that appeared with regularity throughout the series (all other regular cast members were from either the Original Series or the films). In addition to the main series, Tuchinsky also had an appearance in the graphic novel Debt of Honor.

• Custom Uniform of Sexy: Tuchinsky is the only known character to have paired the top of an enlisted crewman's jumper with a female officer's skirt. She's also worn both the full enlisted jumper and an officer's uniform.
• Deadpan Snarker: Tuchinsky received relatively little development over the course of the series, barely being more than a face and a name behind the transporter control panel. About the one personality trait that was really established is a tendency for wry observations about the goings on around her, and wondering why she joined Starfleet when Enterprise comes under fire from the Nasgul.
• '80s Hair: She sports a rather impressively coifed mane, particularly in Debt of Honor.

Other Starfleet and Federation Officers

R.J. Blaise

A Protocol Officer assigned to Enterprise after one interplanetary incident too many, Blaise immediately butts heads with Kirk's loose interpretation of the Prime Directive. Their situation isn't helped that she and Kirk are immediately mutually attracted to one another.

• Action Survivor: R.J. is not Starfleet. She's had no combat training, and isn't at all physically imposing. She nonetheless manages to acquit herself well while she and Kirk are escaping Sweeny's ship.
• Barely-There Swimwear: Her swimsuit in issue 10 barely even qualifies as that. It's cut extremely high on her hip, has a thong back, is very narrow around the crotch in front, and oh yeah, doesn't cover her right breast at all.
• The Bus Came Back: Reappears in Special #1 to resolve her and Kirk's Unresolved Sexual Tension, then is sent packing once again.
• Butt-Monkey: She becomes a frequent target of pranks and insults, both veiled and otherwise, from the rest of the crew. A particular favorite is to trap her in turbolifts sending her down to Deck 10.
• Can't Spit It Out: She quickly develops an attraction to Kirk, which only further strains their working relationship. However she's also unable to actually tell him how she feels, for a variety of reasons.
• Custom Uniform of Sexy: Justified, as R.J. is not a member of Starfleet, and is instead attached to the diplomatic office. She therefore opts for a collection of business-style suits, dresses, and tunics.
• Deadpan Snarker: Although on the receiving end of quite a bit of subtle mockery, R.J. gives as good as she gets, usually at Kirk's expense.
• Embarrassing First Name: Her father named her "Raspberry Jam," against her mother's objections. She of course insists on going by "R.J."
• The Fashionista: Although she doesn't openly discuss fashion, R.J. is never shown wearing the same outfit twice, and is as a rule impeccably dressed in a wide selection of business-style suits and dresses.
• The Political Officer: She's a Protocol Officer assigned to Enterprise to keep tabs on Kirk, and (try to) keep him out of trouble. This, of course, leads to much of the friction between them.
• Put on a Bus: The eventual In-Universe reason for her departure was that her feelings for Kirk made it impossible for her to continue as Protocol Officer
• Too Much Alike: Part of why she and Kirk butt heads so frequently is because they're a lot alike. Their shared love of Shakespeare is also one of the first things that truly begins to bridge the gap between them (conveniently right before she's Put on a Bus).
• What Happened to the Mouse?: Her post aboard Enterprise is extended after the conclusion of Kirk's trial, and she's with the crew when they awaken the Worthy from stasis. However she vanishes for the rest of the arc, and is never mentioned again until and appearance in Special #1 several years later.^note Peter David was ordered by Roddenberry to remove R.J. from the book, and was not even permitted to write her out. So she was simply dropped without a word

Lt. jg. Martin Lukas

Chief Engineer of USS Excelsior.

• Fire-Forged Friends: while not friends, when Sulu first takes command of Excelsior, Lukas isn't exactly confident in his capabilities, which earns him a dressing-down by Commander Rand. By the end of the Tabukan crisis, Sulu has earned his full respect.
• Gadgeteer Genius: He's a Starfleet Engineer, so that goes without saying. He's able to devise a dampening field enabling Starfleet to use their transporters to move the Tabuka warheads, with a little guidance from Scotty.
• Green-Eyed Redhead: Flaming orange hair and green eyes.
• Teetotaler: Scotty gifts him with a bottle of his finest Scotch, and Lukas confesses to his shock that he doesn't drink. They do end up sharing a glass anyway while brainstorming how to move the Tabukan warheads via transporter.

Ambassador Mirenna Dora / B'Non

A Federation ambassador assigned prepare the planet Zuyna for admission to the Federation. Dora runs afoul of the planetary leader, Dranna Zahn, over the treatment of a species called the B'Tin; a peaceful, if primitive, race inhabiting land that the Zuynans wanted to strip mine. Dora brought one of the B'Tin she befriended, B'Non, to the capital in an attempt to develop some sort of relationship between the two cultures, but Zahn and his people refused to negotiate, believing the B'Tin to be unintelligent life forms, and that they had the right to do whatever they wished with the land the B'Tin inhabited. Dora was killed helping B'Non escape, at which point he took her shape and replaced her without the knowledge of Zahn or his people.

• Heroic Sacrifice: The real Dora died trying to help B'Non flee the Zuynans.
• House Arrest: Is effectively under this due to her objections to the Zynans' treatment of the B'Tin.
• Shapeshifter: The real Dora was killed before Enterprise's arrival. The woman Kirk meets with is actually B'Non, who has taken her shape.

Vice-Admiral/Admiral Karl Tomlinson / Kerzuk

First introduced as a liaison officer between Starfleet and the Federation Council, Tomlinson butts into the negotiations between the President, Klingon Ambassador, and the Salla of the Nasgul over how to handle Kirk. His bull-headedness eventually leads to Nogura kicking him upstairs to get him out of the President's hair. He's also actually a Klingon in disguise, and a mole planted in Starfleet Command.

• Foreshadowing: His true identity is first hinted at during a conversation with Nogura, when he asks for Tomlinson's opinion on a possible redesign of the Constitution-class cruiser that would make it remarkably similar in configuration to the later Galaxy-class starship. Tomlinson's response focuses on the design from a martial perspective. At the time it's dismissed as just the way Tomlinson thinks, but the reveal that he's actually a Klingon in disguise phrases his response in a whole new light.
• Jerkass: He's rude, abrasive, aggressive, and, ironically considering the charges Kirk faces, has little patience for protocol by butting in on the President's negotiations with the Klingon Ambassador and the Salla. It makes sense once he's revealed to be a Klingon operative.
• Kicked Upstairs: After the conclusion of Kirk's trial, Tomlinson is promoted to Starfleet Operations. It's intended to be this, by removing him from a prestigious assignment as liaison between Starfleet and the Council, however Tomlinson disagrees. It certainly puts him in the position to do far more damage to the Federation than his old assignment.
• The Mole: He's actually a Klingon named Kerzuk planted in Starfleet Command.

Klingons

Baraga

A warlord notworthy for his brutality even among Klingons. His untimely assassination by time traveling Romulan agents changes the course of Klingon history.

• Ace Pilot: Baraga was an early proponent of aircraft, and their utility as weapons of war. Romulan agents attempted to assassinate him by sabotaging his personal flying machine. When Kirk and company reveal the plot, he convince Baragas to allow them to think the plot succeeded in order to flush them out.
• Affably Evil: Sure he's violent, bloodthirsty, and sadistic, but damn if he isn't also highly charismatic and charming when he wants to be.
• Bad Boss: Baraga decides he wants Kirk and Sulu as his personal mechanics after they prove able to repair and maintain the finicky primitive Klingon aircraft. When Kirk points out he already has a mechanic, Baraga shoots the man dead on the spot, creating a vacancy.
• Large Ham: Even as Klingons go. Baraga devours every panel he appears in hole, and picks his teeth with the frame.
• Roaring Rampage of Revenge:
  • It was the rampage resulting in the aftermath of his assassination that ultimately prevents the foundation of the Klingon Empire, and helps put the Klingons on a second path towards peace, when several key figures in Klingon history are killed in the purge.
  • After the assassination is foiled, Baraga announces plans to paint the streets with the blood of the conspirators with one of his own on the local radio.

Khartan

An early Klingon leader who was a philosopher more than a warrior, had Khartan not been assassinated as part of a coup by his treacherous captain of the guard, he might have led the Klingons down a much different path.

• Inspirational Martyr: A failed example: Khartan's philosophies could have changed the course of the Klingon Empire, creating a society of artists, philosophers, and poets rather than the Planet of Hats Proud Warrior Race Guys we all known and love.^note Although ironically enough, The Next Generation and Deep Space Nine would reveal that for all their bloodied history the Klingons still developed a deep love and appreciation for poetry. And Shakespeare. Rather than memorializing him, his assassination unleashed a violent series of reprisals that helped to establish the Klingon Empire known today.
• Too Good for This Sinful Earth: Kirk only bitterly accepts that the only way to set the timeline right again is for Khartan, a man whom he comes to deeply admire and respect in the short time he has known him, but be assassinated.

Commodore Khezri

A ranking officer in the Klingon Defense force, Khezri commands the Klingon battlecrusier IKS Qapla'. Enterprise has encountered him on several occasions.

• Cultured Badass: He's a musician in his downtime.
• Reasonable Authority Figure: Where Klaa is aggressive, vindictive, and obsessed with the idea of avenging himself upon Kirk for his humiliation over the Nimbus III, and the Klingon Ambassador clings to a desire to see Kirk punished over what he views as decades of transgressions against the Empire, Khezri is far more pragmatic. Even if he doesn't fully trust Kirk, he's not overtly hostile, and has assisted Enterprise on several occasions.

Maroans

The Maroans are relative newcomers to the galactic scene. They are seeking an alliance with the Romulan Star Empire, and are attempting to prove themselves by hijacking shipments of Tabukan weapons being removed from the planets for disposal as part of their armistice.

• Fangs Are Evil: Maroans have sharp canines that often protrude from their jaws when their mouths are closed.
• Four-Fingered Hands: Three and a thumb.
• Red Eyes, Take Warning: One of the Maroans' most distinguishing feature are there large, glowing red eyes.
• Stealth in Space: The Maroans have cloaking technology, however it's several generations out of date, and Enterprise is able to detect them with little trouble.

Brekara

Leader of the Maroans. She is the one pursuing the alliance with the Romulans, and in overall command of her peoples' attempt to steal the stockpile of Tabukan warheads.

Commander Horalt

A senior commander in the Moran assault force, Horalt commands the ships monitoring the Tabukan asteroids where the weapons disposal operation is taking place. He leads the final effort to sweep in and secure the warheads, but is ambushed by Enterprise and Excelsior. Horalt chooses to Ram Excelsior rather than surrender, but is killed when Enterprise destroys his ship with a single phaser blast.

• Defiant to the End: With their attack plan in shambles, their ground forces captured, and facing the combined firepower of two Federation starships — each of which alone demonstrated themselves fully-capable of curb-stomping entire squadrons of Maroan ships — Horalt still refuses to surrender. Instead he sets a collision course with Excelsior to buy time for Brekara to escape safely into Romulan space.
• Villainous Valor: He refuses to surrender when the attack on the Tabukan arsenal fails, and instead buys time for Brekara to escape by ramming Excelsior.
• Reasonable Authority Figure: Unlike the impulsive glory hound Vodrin, Horalt is focused on the task at hand. He's fully aware of the risks of their operation, and insists that Brekara not expose herself when she attempts to take personal command of the squadron for the final assault. Horalt recognizes that she's far more important to their people, and refuses to allow her to needlessly risk her life.
• Undying Loyalty: To Brekara, which is much more than can be said for her son. Horalt's last act is to ram Excelsior to safeguard her escape when the Tabukan operation fails.

Commander Vodrin

Brekara's son, and commander of one of the divisions of the Maroan fleet. He has an inflated opinion of himself, and rather than carrying out his mother's orders is instead determined to set himself up as a warlord on Epsilon Kitaj.

• An Arm and a Leg: [[spoiler: Loses his right arm in a bombing attack on his headquarters when the people of Epsilon Kitaj rebel against him.
• Despotism Justifies the Means: Vodrin continues to gas the people of Epsilon Kitaj even though he's supposed to rendezvous with the rest of his mother's forces, executes anyone who attempts to violate his blockade, and enacts harsh punitive measures on anyone resisting his attempt to exert his control over the planet.
• Glory Hound: His desire for his own personal glory leads him to attempt to capture Epsilon Kitaj, depriving the Maroan forces of his ships.
• Nice Job Fixing It, Villain: Had he regrouped with his mother as he was ordered, it's likely the Federation would have never connected the Epsilon Kitaj attack with the attacks on the Tabukan weapons convoys. Furthermore intelligence recovered by the capture of Vodrin and his ships enabled Kirk and Sulu to plan their ambush of the remaining Maroan forces. It probably wouldn't have made too much of a difference in the long run, but his actions made it significantly easier for the Federation to defeat them.
• Small Name, Big Ego: He thinks very highly of himself. Granted, he is the son of his peoples' leader, but his attempt to set himself up as despot of Epsilon Kitaj nonetheless exceeds his capabilities. Especially once Enterprise returns, and the locals get fed up with his heavy-handed rule.

Pilkorans

A highly-isolationist and xenophobic race. Some thirty years earlier a new regime attempted to bring their people out of self-imposed exile, and even expressed an interest in joining the Federation. However by the time their ambassador completed a tour aboard Farragut, the isolationists had forcibly seized power again.

• Fantastic Racism: Pilkorans don't much like anyone other than their own kind. In fact one of the worst insults in their language is the term hajoka, which roughly translates as "foreign.

Victoria Leigh Kegin

Victoria Leigh Kegin is a human and former Starfleet officer who married a Pilkoran and became a citizen. An old friend of James T. Kirk, Vickie attended Starfleet academy with him. Although she had a romantic interest in him they remained merely friends, as Kirk was pursuing Carol Marcus at the time. Upon graduation they shipped out together aboard Farragut, where Vickie met her future husband: Tred Kegin, an ambassador from Pilkor III, which was just ending its isolation. The two fell in love while Tred traveled aboard Farragut, but upon returning him home they learned that the Isolationists overthrew the new government, and ended any hopes for Pilkor joining the Federation. Captain Garrovick married the pair, and Vickie resigned her commission to be with him. Thirty years later, she sought out Kirk at a Starfleet Academy reunion to reveal that Tred had been killed, and named Kirk his sole heir.

• '80s Hair: Her massive blonde coif would do any female character from Dynasty (1981) proud.
• Blackmail: Vickie is being forced by Pilkoran authorities to lure Enterprise near the Neutral Zone as part of a plot to start a war between the Federation and Romulan Empire. If she doesn't comply her husband, who was actually imprisoned, will be killed. Vickie secretly works with Kirk and crew to turn the tables on them.
• Blackmail Backfire: Thanks to Kirk's help, Vickie is able to turn the tables on the Pilkoran authorities, rescuing Tred and stymieing their attempts to start a war between the Romulans and Federation.
• Crusading Widow: Vickie believes that Pilkor is planning something that threatens the Federation, and that this is why Tred was killed. She seeks out Kirk in hopes of exposing the threat.
• Everything's Better with Sparkles: Her evening gown at the Academy reunion is already sexy as it is. But it also sparkles.
• Impossibly-Low Neckline: The evening gown she's wearing when she first meets Kirk at the reunion combines this with Sexy Backless Outfit to dramatic effect.
• The Mole: Is supposed to be one working for the Pilkorans in their attempts to spark a war between the Federation and Romulans. However she's not doing it willingly, and double-crosses them with Kirk's help.
• Sexy Backless Outfit: When she first meets Kirk at the reunion she's wearing a slinky evening gown with an Impossibly-Low Neckline, a sky-high slit, and a low back.
• Sexy Slit Dress: The first outfit she wears is a slinky evening gown with a slit up to her thigh.
• Unlucky Childhood Friend: Vickie was interested in Kirk when they attended the Academy together, but they never went beyond platonic, as he was pursuing a relationship with Carol Marcus at the time.

Tred Kegin

A Pilkoran nobleman and once an ambassador to the Federation during the brief window of Pilkor III's interest in joining the Federation. He fell in love with Victoria Leigh while traveling aboard USS Farragut during his mission, and his fondest hope was that Pilkor would indeed become a member of the Federation. His hopes were dashed upon his return home, and discovering that the isolationists had seized power in his absence. He married Vickie aboard Farragut before the two of them returned to Pilkor together, but he never stopped fighting to see his homeworld break free of their isolation. He eventually founded a resistance movement as part of the effort, and uncovered a mysterious government endeavor called Project Quest, with potentially sinister implications for the Federation.

• Distressed Dude: Although claimed by Vickie to be dead, he's actually a political prisoner being held to leveraging her into assisting the government with their plot to push the Federation and Romulans into war.
• La Résistance: He founded the resistance against the isolationists currently ruling his planet.

Leeta

A young Pilkoran who survives an attack on her colony world. Unbeknownst to her, she's merely a pawn in Pitkemeni's plot.

• Fake Memories: Leeta is implanted with a device that interferes with her memory, overriding her real past with a fake background. The device is intended to make her believe her people were attacked by the Romulans.
• Sole Survivor: The only survivor of an attack on a Pilkoran colony, whom she claims was destroyed by the Romulans.

Minister Pitkemeni

A high-ranking official of the Pilkoran government. Pitkemeni is a central figure in Pilkor's attempt to start a war between the Federation and Romulans. She has kidnapped Victoria Kegin's husband, and is using him to leverage her into assisting their efforts.

• Blackmail: Pitkemeni kidnapped Vickie's husband, and is holding him as leverage to force her to lure Kirk and Enterprise to the Neutral Zone as part of her plot to start a war between the Romulans and Federation.
• Moving the Goalposts: Vickie's part in her plot was simply to get the Federation to send a ship, after which Pitkemeni was to release her husband. Pitkemeni immediately reneges on the agreement, and insists on being certain the plan actually succeeds before holding up her end. After Kirk and crew fake a message suggesting Enterprise was destroyed and war was eminent, she moves the posts yet again.
• Screw the Rules, I Make Them!: When Vickie remarks that Pilkor law protects her citizenship despite her husband's death, and that if she doesn't like that Pitkemeni would have to change the law, Pitkemeni makes it clear that option is already being explored.

Quatrini

The Quatrini are a race of large-eared Humanoid Aliens with distinct markings around their eyes. They're native to the planet Quatrin, and their society has a divided class system. They're currently fighting an armed uprising by workers on the planet Beta, the paradoxically-named fourth planet of the Quatrin System.

Quatrini

Security Director Prusk

Head of the Quatrin Security Agency, Director Prusk is investigating the attack witnessed by Sulu and Uhura. He secretly orchestrated the assault himself in an attempt to launch a Coup D'état to seize power for himself, by framing the Betans for carrying out the assassination as a means of getting emergency police powers pushed through the Quatrini government. He tries to have the pair killed in an attempt to clean up any potential witnesses to his involvement.

• Da Chief: Is director of Quatrin's internal security department, sort of like a combination of the FBI and CIA.
• False Flag Operation: He sends his operatives to murder other operatives who are attempting to turn over a Betan terrorist, so he can then blame it on the Betans themselves as a means of encouraging the government to grant him emergency powers.
• Fat Bastard: Prusk is short and portly, and is plotting to seize power in the Quatrin System.
• Large Ham: His speech before the hearing on whether or not to grant him emergency powers is in all caps from virtually start to finish. He also tends to yell at his subordinates a lot.
• Leave No Witnesses: Tries to have Sulu and Uhura killed just in case they know too much.
• Xanatos Speed Chess: Prusk reacts quickly to every hitch in his plan. Two Starfleet officers witness a murder he wants to pin on the La Résistance? Insist that they testify, use political wrangling to separate them from security escort, and have his best agent bump them off so he can blame that on the resistance, too. And when that gets bungled he sends his other best man in to finish the job. Unfortunately the one thing he couldn't work around — the survival of one of the intended murder victims, safely out of reach in Enterprise's sickbay — is what ultimately brings him down.

Colonel Gavok

Leader of an elite Quatrin Security unit, Gavok was part of a False Flag Operation to frame the Betan terrorists for assassinating one of their own leaders, and the Quatrini agents who apprehended him. He's later dispatched to Beta to clean up the mess.

• Groin Attack: Uhura gives him a knee right to the jewels when he threatens her, effectively putting him out of action.
• The Heavy: Plays the most direct role in executing Prusk's plans. He's the one who murdered Bokkan and the Quatrini agents who captured them, and later commands the attempt to hunt down Sulu and Uhura after their escape.
• Leave No Witnesses: His orders from Prusk.
• Sadist: Takes almost perverse satisfaction in his orders to Leave No Witnesses, and commands his team to kill any Betans who might be harboring Uhura and Sulu.
• Smug Snake: He's highly disparaging of Ronago, and believes the man has an elevated opinion of his abilities and importance. He ignores the fact that the entire reason there's a mess to clean up in the first place is because he failed to complete the job first.

Senior Agent Ronago

Prusk's right-hand man.

• Better to Die than Be Killed: He's accidentally stabbed by his own knife in a struggle with Sulu, and elects to kill himself rather than bleed to death or allow Sulu to finish him off. He actually relishes the idea of dying by his own hand.
• The Big Guy: He's about a head taller than Sulu.
• Crazy-Prepared: He doesn't take any chances when he attempts to kill Sulu and Uhura. He activates the shuttles auto-destruct to finish the job in the event he fails.
• Leave No Witnesses: The reason he tags along on the shuttle returning Sulu and Uhura to Enterprise.

Turia

A female Quatrini aide to Director Prusk.

Yujikian

Colonel Gavok's second-in-command.

Betans

Bokkan

A high-profile Betan insurgent who was captured by the Quatrini. The murder of both him — and the Quatrini agents who captured him — by Colonel Gavok sets the plot in motion.

Ros

Leader of one of the Betan terrorist cells. He comes across Uhura and Sulu after they're stranded on Beta following Ronago's assassination attempt.

• Blackmail: Forces Uhura to repair his cell's communications equipment by threatening to withhold medical treatment from Sulu when he goes into an arrest.
• Cool Shades: As Beta is an arctic planet, sunglasses are a necessity to protect one's eyes from the glare of sunlight on snow. They're standard issue among the rest of his contingent, as well.
• Good Is Not Nice: He's a generally decent man, but hardened by the stress and needs of fighting the resistance against Quatrini efforts to subdue the denizens of Beta.
• Your Terrorists Are Our Freedom Fighters: He firmly believes that his people are fighting to protect their homes from the Quatrini, particularly as Quatrin has no interest in preserving Beta's unique biosphere in their hunger for mineral wealth and resources.
• Reasonable Authority Figure: Willing to help Uhura and Sulu after they land on Beta (though see Good Is Not Nice above), and watches Uhura's back while she sneaks into a Quatrini staging area to contact Enterprise. His followers are also steadfastly loyal, even when they disagree with him.

Ferian

A healer under Ros's command. She's acerbic, cranky, and irritable, but nonetheless a competent healer.

• Catchphrase: "I'm a healer, not a..."
• Deadpan Snarker: This seems to be a requirement for highly-qualified doctors in the Star Trek universe.
• Distaff Counterpart: She may as well be McCoy with koala-like ears and boobs.
• I'm a Doctor, Not a Placeholder: As if there's any more evidence needed for Distaff Counterpart above, she freely cribs McCoy's Catchphrase. Uhura has a private chuckle over it.
• The Medic: Farian is a healer assigned to Ros' terrorist cell.
• That Old-Time Prescription: Partly out of necessity, partly because of her familiarity with Beta's unique flora. When Sulu dies — twice — from injuries he sustained from Ronago's assassination attempt, she's able to revive him successfully without any resuscitation equipment (or even CPR, for that matter) thanks to a few oblia leaves.

Romulans

Admiral Jaricus

A high-ranking commander in the Romulan fleet, Jaricus is supervising the Maroan efforts against the Tabukan system, and evaluating them as potential allies. Although at first impressed with their intelligence gathering capabilities, he coldly tells Brekara that Romulans don't give second chances when her efforts fail. He later returns as part of a plot to establish Romulan dominance over the Federation and Klingons by using time travel to manipulate history.

• Nice Job Fixing It, Villain: His attempt to manipulate history so that the Romulans become the dominant power in the galaxy don't exactly work out. In fact, they become downright disastrous when it turns out that rather than empower the Romulan Empire, the changes he made led to its annihilation at the hands of the Federation and Klingons.

Tabukans

Recently admitted to the Federation, the Tabukan System centers on two planets, Tabuk III and IV, who have just emerged from an extended Cold War. They have, as a result, stockpiled an enormous cache of weapons that they request Starfleet's assistance in finding a way to safely dispose of.

• Beast Man: Tabukans look sorta like four-armed, four-eyed bipedal horses.
• Extra Eyes: They have two pairs of eyes.
• Lensman Arms Race: For two centuries the focus of Tabukan scientific advancement has been on a race between the planets of Tabuk III and IV to build bigger and better warheads, until the point they've stockpiled enough firepower they could destroy one another a thousand times over. Part of their reason for joining the Federation was for their help mediating an end to the conflict, and finding a way to safely dispose of the weapons.
• Multi-Armed and Dangerous: Tabukans have four arms.

President Sodridj

The President of the Tabuk System. Sodridj originated on Tabuk IV, and was in office when Tabuk requested the Federation's aide with dismantling the massive arsenals on Tabuk III and IV.

• Sesquipedalian Loquaciousness: Sodridj tends to be rather long-winded, much to the annoyance of her counterpart from Tabuk III, Gefion.
• We ARE Struggling Together: Almost comes to blows with Gefion when a saboteur from Tabuk III is discovered attempting to interfere with the disarmament, however the conflict ends after a rebuke from Sulu.

Deputy Gefion

Deputy to President Sodridj, from Tabuk III.

• We ARE Struggling Together: Almost comes to blows with Dodridj when a saboteur from Tabuk III is discovered attempting to interfere with the disarmament, however the conflict ends after a rebuke from Sulu.

Sweeney

An infamous bounty hunter whose very name instills fear in everyone who hears it. When the Klingons offer a bounty of "riches beyond compare" to anyone who brings them the head of James T. Kirk, Sweeney takes an interest.

• Actually a Doombot: Kirk gets into a fight with Sweeney on the bridge of his command ship, while attempting to lower the ship's shields so Spock and R.J. Blaise can escape. Kirk is astonished when a second Sweeney appears on the bridge with an armed party. Turns out the man Kirk has been tussling with is a decoy. An explosive decoy. However the book never explains what, exactly, it was.
• Affably Evil: Although he's quite ruthless, he remains unfailingly polite, and never once raises his voice in his appearances. Even when things aren't going his way he never visibly loses his cool.
• Bad Boss: Despite his pleasant demeanor, his men are terrified of him. Gaz learns this the hard way when he mistakenly acknowledges Sweeney's own musings that losing Kirk could be damaging to his reputation.
• Cultured Bad Ass: Plays chess and enjoys listening to Mozart.
• The Dreaded: Even Klingons are terrified of him.
• Eye Beams: Not exactly. But he has a pair of goggles that can shoot a high-powered phaser blast.
• Goggles Do Something Unusual: His fire a phaser blast.
• Large and in Charge: Subverted. When first introduced he's a positively massive figure obscured in shadows, befitting his terrifying reputation. It turns out that this is just a front, however, as Sweeney himself is actually a fairly average human.
• No-Sell: One of the only people ever shown shrugging off the Vulcan Nerve Pinch. Spock is quite displeased, while Sweeney refuses to tell him how he managed it.
• Phrase Catcher: Any time his name is mentioned, everyone in ear shot shouts, "Not Sweeney!"
• Smart People Play Chess: He loves the game, but none of his crew will play him out of fear they might actually win. Spock has no such fear.
• Sore Loser: None of Sweeney's crew will play chess with him out of fears of this. Turns out they're rather well-founded. When Spock beats him in a game, Sweeney analyzes the board to confirm, and then vaporizes it.
• Why Am I Ticking?: The Sweeney decoy Kirk fights starts building up to a detonation the moment Scotty is able to beam them both aboard Enterprise. Fortunately, they're able to quickly send it into space again. The blast is so powerful that it blinds Klaa on the bridge of his Bird of Prey!

Dr. Abigail Wilson

Abby Wilson is an old friend of Dr. McCoy's from medical school. She formerly served as the Chief Medical Officer aboard USS Lexington, before resigning over charges of insubordination stemming from an incident in which she defied orders to provide medical attention to injured pirates following a raid. Wilson's private vessel, SS Salutaris, arrived at Epsilon Kitaj ahead of Enterprise in response to the same distress call, and is captured along with McCoy when Vodrin begins his conquest.

• Honor Before Reason: Abby's first, last, and only concern is for the well-being of others, even to the point of violating orders or a disregard for her own safety. When Vodrin is badly wounded by a resistance attack, she risks the wrath of the colonists to treat him out of her sense of duty to the Hippocratic Oath.
• Inconvenient Hippocratic Oath: Only to those who have to deal with her, as she puts her oath as a doctor ahead of everything else, treaties and regulations be damned.
• Jerkass: She's rude and abrasive, and has little patience for anyone who challenges her mission.
• Jerk with a Heart of Gold: Despite all that, she genuinely cares for people, and her foremost thought and concern is providing medical attention to anyone who might need it.
• Military Maverick: Back when she was C-M-O of Lexington. Abby could be downright insubordinate when her oath to Starfleet compromised her ability to uphold her Hippocratic Oath. Her Starfleet career ended when she willfully disobeyed orders to search for survivors of a pirate ship crash, protect them from their vengeful targets, and provide medical care to their wounded.
• Start My Own: Dissatisfied with Starfleet over the incident with the pirates, Abby resigned her commission and bought her own ship to convert into a hospital vessel.
