The dominant Sebacean culture, a completely militarised society constantly seeking to expand their zone of conquest.
- Commie Nazis: Their aesthetics are a deliberate fusion of the Third Reich and the Soviet Union's short-lived modernist period. (The Peacekeeper emblem is based on the famous abstract Bolshevik propaganda poster "Beat the Whites with the Red Wedge".)
- Conservation of Ninjutsu: The smaller the group of Peacekeepers, the deadlier they seem to be — to the point that individuals seem almost unstoppable.
- The Empire
- Faceless Goons: Peacekeeper troopers.
- Fantastic Racism: Quite apart from their distrust of non-Sebaceans — sometimes to the extent of discharging soldiers for "Irreversible Contamination" — hybrids are treated with utter contempt. However, the Peacekeepers are practical enough to recognize the value of keeping individuals like Scorpius around.
- Humans Are the Real Monsters: Human Aliens, actually, but they're the most human-looking extraterrestrials in the series, and the primary antagonistic force of fascistic, militaristic nutcases. In The Peacekeeper Wars the Eidolons are strongly indicated to have created the Sebacean by modifying prehistoric humans.
- Imperial Stormtrooper Marksmanship Academy: Not entirely the case with all Peacekeepers — see Conservation of Ninjutsu.
- A Lighter Shade of Black: While certainly not good, compared to the Scarrans they're downright saints. In fact all of their actions throughout the series are centered around confronting and containing the Scarrans lest they run roughshod over the rest of the galaxy.
- Love Is a Crime: All forms of relationship other than military comradeship are brutally punished. Casual sex is OK, but you better not fall in love with anyone.
- A Nazi by Any Other Name
- Private Military Contractors: An entire empire of them, with a nasty habit of conquering their clients.
- Putting on the Reich
- Space Police: Hence the name "Peacekeepers". They were created by the Eidolons as a neutral military peacekeeping force, and now act as interstellar law enforcement and defense for less powerful planets and species. Unfortunately this power is open to abuse, with the Peacekeepers allying with planetary rulers who use their power as a big stick to maintain their own positions. Hence the Peacekeepers control an empire by proxy.
- The Spartan Way: Peacekeepers are either born into the organisation or forcibly recruited as children, then brought up brutally and lovelessly to see duty and discipline as the only things that matter; friendships (sometimes with "benefits") are permitted among the soldiery, but any relationship approaching love is terminally discouraged — as Xhalax Sun discovered.
- Well-Intentioned Extremist: The Peacekeepers really are trying to keep the peace as best they know how. Unfortunately with the disappearance of the Eidolons who created and guided them, that meant at the muzzle of a pulse rifle, and forcing their will on others. They're also doing everything in their power to protect the rest of the galaxy from the menace of the Scarran Imperium, and unfortunately that means making a lot of questionable moral choices.
Grand Chancellor Maryk
The leader of the Peacekeeper military during much of the Peacekeeper/Scarran War. His headquarters at Peacekeeper Strategic Command, Maryk is able to coordinate the considerable Peacekeeper military and issue his orders throughout the fleet.
As leader, Maryk is a very cautious man, perhaps to a fault. He is strongly opposed to an open war with the Scarrans believing that being outnumbered and out-gunned, the Peacekeepers have almost no chance of victory.
Commandant Mele-On Grayza
A manipulative and decadent senior Peacekeeper officer, who becomes Scorpius's rival for power within the organisation.
- Absolute Cleavage: Or, as Crichton refers to her, "Commandant Cleavage."
- Bad Boss: Grayza had a tendency towards unreasonable demands towards her subordinates, and punishing them harshly when they failed to meet them. In one case, a technician designing a torpedo designed specifically for killing Leviathans warned her and Braca the weapon wasn't ready. Although Braca was willing to listen to her expertise, Grayza pressured him into ordering the weapon deployed anyway. When it inevitably failed as the tech predicted, Grayza ordered the poor woman to the Aurora Chair for the failure. Even though the tech warned her the weapon wasn't ready.
- Big Bad: For the first half or so of Season 4.
- Bizarre Alien Biology: Thanks to a gland implanted in her chest, she can secrete a powerful pheromone that goes beyond mind control. This leads to John Crichton's big aversion of the Double Standard: Rape, Female on Male trope.
- Double Standard: Rape, Female on Male: Averted, although she certainly seems to believe that what she's doing isn't rape.My interrogations are much more agreeable than Scorpius' methods.
- Express Delivery: Between Season 4 and the miniseries.
- Expy: In appearance and personality, she bears a strong resemblance to Servalan, the Big Bad of Blake's 7.
- Femme Fatale
- General Failure: The crew of Moya largely only managed to escape Scorpius by the skin of their teeth and it took two whole seasons to finally deliver him a truly crippling victory. Grayza, by contrast, made it outright easy for them to run circles around her. Never mind her utter failure at managing the Scarran threat actually convinced them the Peacekeepers were even weaker than they appeared. She's the only Peacekeeper commander in the entire series to be removed from command by her own crew in a full-scale mutiny.
- Head-in-the-Sand Management: Her attempts to appease the Scarrans in Season 4. She's obvious enough about it that it actually tips them off that the Peacekeepers are weaker than they had thought.
- Idiot Ball: When she first challenges Scorpius, she claims that wormholes have no military application - in front of the ambassador from a known-to-be-militarily-competent race. Granted, this may have been to taunt Scorpius over the imminent shutdown of his project, but she also espoused a strategy that absolutely would not work against the Scarrans and pooh-poohed the frank assessment of the effectiveness of said strategy by the Peacekeepers' biggest expert on Scarran psychology and culture (Scorpius, who had spent the first years of his life being raised by them).
- Klingon Promotion: The superior she kills is also strongly implied to be the father of her unborn child.
- Mama Bear: It's implied that the main reason she goes along with Crichton's demands in "The Peacekeeper Wars" is to protect her unborn child.
- Mind Rape: The Heppel oil secreted by a gland implanted in her chest acts as an extremely potent pheromone, with which she uses to rape Crichton.
- Real Life Writes the Plot: Rebecca Riggs really was that heavily pregnant when "The Peacekeeper Wars" was filmed: she'd thought that the show was cancelled permanently and decided it was time to have a child. She also missed "Bad Timing" because of her wedding. Grayza was consequently said to be detained and sedated in the episode.
- Smug Smiler
- Smug Snake
- Villainous Breakdown: After Crichton makes her realize her plans for peace have failed, she goes through this, though regains some sanity later.In my hands - you can have peace! I! CAN! HAVE! PEACE!
- What Could Have Been: It is never made entirely clear if the father of her unborn child is Crichton or Maryk.
Commander Tollona Javio
A Peacekeeper officer and the commander of the Gammak Base visited by John Crichton near the end of his first cycle in the Uncharted Territories.
A junior officer under Scorpius and his most faithful follower. As he gains character development, it becomes clear that his feelings for his boss, while ambiguous, go far beyond those of the average minion.
- Ambiguously Bi: Definitely has feelings for Scorpius. His attraction to Grayza, however, could have just been the Heppel oil messing with his head.
- And This Is for...: When he's giving Scorpius a good kicking after becoming note Grayza's Dragon:Braca: This is for all the times I've had to say "yes"!
- Ascended Extra: He started out as a generic Peacekeeper that Scorpius would talk to in order to provide the audience with exposition. Over time, Braca started gaining his own personality. He becomes increasingly important to the plot, to the point where he is given the honor of fighting alongside the heroes during the miniseries' final battle.
- Badass Beard: Grows a goatee in time for the miniseries.
- Crichton humiliates him on a regular basis.
- Braca spends most of "I-Yensch, You-Yensch" wearing a bracelet that makes him feel everything that D'Argo feels. After a bunch of comedy at Braca's expense, the good lieutenant gets shot and spends the rest of the episode trying not to bleed out.
- For a few episodes in Season 4, Grayza uses her pheromones on him only to refuse his pheromone-induced advances, both because it amuses her and so she can use him as a living communicator so she can speak with a telepathic assassin without anyone knowing.
- The Captain: Is a Lieutenant for most of the series, until he is later promoted to Captain. He is later promoted to Admiral in the comics.
- The Dragon: To Scorpius, and then later to Grayza. Later episodes revealed that he was still loyal to Scorpius even while working for Grayza.
- Co-Dragons: Braca and Sikozu are this to Scorpius, during Season 4 and the miniseries.
- Fantastic Racism: At first, he's not too pleased at having to serve under a half-breed like Scorpius. He grows out of it once he realizes that Scorpius is the one thing standing between the Peacekeepers and their destruction at the hands of the Scarrans.
- Last-Name Basis: His first name isn't revealed until the second-last episode of the series.
- Mauve Shirt: Braca was originally just another mook in a couple of late Season 1 episodes, but Scorpius needed a number two and David Franklin was such a damn good actor that he eventually got a Mook Promotion.
- Mook Lieutenant: Starts as one. He gives Scorpius someone to talk to.
- Mook Promotion: From a random Peacekeeper soldier to "Captain Meeklo Braca, Officer of the Fleet, Peacekeeper Interplanetary Service".
- Reasonable Authority Figure: Braca may be one of the Peacekeepers' most genuinely competent and reasonable flag officers. Whereas Scorpius, Grayza, and Crais were notorious for their Bad Boss and You Have Outlived Your Usefulness tendencies, Braca generally demonstrates a much fairer hand. IE: When a technician designing a Leviathan-killing torpedo warned him the weapon wasn't ready, Braca was willing to give her more time to complete her tests, and it was only when he was overridden by Grayza that he ordered it to be deployed.note
- Subordinate Excuse: His feelings for Scorpius quite clearly go way beyond simple loyalty or careerism, shown most blatantly by how emotional he becomes when he thinks Scorpius is putting his own life at risk in "Incubator".
Captain Selto Durka
Captain of the lost command carrier, the Zelbinion, Durka was believed to have died over a hundred cycles ago. Viewed by Peacekeepers as one of their greatest leaders, the truth was far darker. In truth, Durka was a hateful, conniving, violent coward, whose malicious cruelty was well above standards, even for a Peacekeeper.
- Arch-Enemy: Of Rygel.
- Bald of Evil: He prefers to keep his head clean-shaven. In fact, some time after his brainwashing is reversed, he goes so far as to cut off the long hair he's grown in the meantime.
- Brainwashed: After being defeated and captured by the Nebari, he was given a very thorough mind-cleansing... which Rygel ended up undoing on their next encounter.
- Broken Pedestal: It was a bit of a shock for Aeryn to discover that one of the greatest heroes of the Peacekeepers was little more than an opportunistic coward.
- Dead Guy on Display: After being killed by Rygel, his head is mounted on a pike and kept as a trophy
- Decoy Get Away: When the battle with the Nebari turned against him, Durka faked his death by killing an improvised Body Double and making it look like a suicide. Not that it helped, as the Nebari easily caught up with him — hence the brainwashing — but Rygel was certainly fooled when he revisited the Zelbinion 100 cycles later.
- Dirty Coward: As Aeryn noted, retreating from an un-winnable battle is one thing, but murdering one of your own officers to put the finishing touches on your own private escape attempt...
- The Dreaded: Rygel is absolutely *terrified* of the guy. Just coming across his old Command Carrier is enough to leave Rygel completely spooked for a while.
- Electronic Eye
- Evil Old Folks
- Eyepatch of Power: While still under the mental cleansing, he covered his artificial eye with an eyepatch.
- Faking the Dead
- General Ripper
- Good Scars, Evil Scars: Has a massive scar running through his right eye, which has been replaced with the above-mentioned prosthesis.
- Miles Gloriosus
- Space Pirate: Turns into one of these after parting ways with the Nebari (and having his mental cleansing undone); he joins the Zenetan Pirates
- Soft-Spoken Sadist
- Torture Technician
- Villainous Breakdown: Towards the end of "Durka Returns", his calm demeanour quickly fades when he realises his plans have been utterly foiled.Crichton! Don't leave me out here! I'll hunt you down and I'll kill you!
A Peacekeeper command carrier captain.
- Fantastic Racism: Averted, at least with Scorpius. While Peacekeepers usually have little regard for other species or hybrids, Molayne gives Scorpius a fair shake and rewards his obvious loyalty.
- Reasonable Authority Figure: To young Scorpius, whom he inducted into the Peacekeepers, even suspending their Purity Regulations on the young hybrid's account.
- Small Role, Big Impact: He both fills Scorpius in on his past and gets him into the Peacekeepers.
A Peacekeeper captain and leader of a group of Special Ops commandos. Boards Moya when his Marauder spacecraft malfunctions, with a mysterious cargo- an intelligent virus capable of taking over the minds of its hosts.
- A Father to His Men: Best demonstrated when he refuses to demand his squad stand at attention when he enters the room. Even if he is their commander, he behaves more like part of the group, and makes a point to Aeryn that he respects his men too much to demand that sort of obedience.
- Grand Theft Me: When taken over by the "Intellant Virus"
- Reasonable Authority Figure: While he does butt heads with Crichton's "Captain" on jurisdictional grounds, Larraq is A Father to His Men, charismatic, and has no compunctions against allying with Moya's crew when the virus he's transporting escapes. His tone even expresses regret when he reveals to Aeryn that extracting the virus from Rygel will kill him in the process.
- Small Role, Big Impact: Despite being a one-off character, the injury he delivers to Aeryn while possessed is what leads the crew to infiltrate the Gammak base... which leads to Scorpius discovering and pursuing Crichton. Larraq's presence changes the entire course of the rest of the show.
- Tall, Dark, and Handsome: No wonder Aeryn falls for him.
- The Determinator: Allows nothing between him and his target. Explicitly called as such by one of his soldiers, and it's why the Virus ultimately settles on him as its host.
Flight Officer Cobrin
An overconfident Peacekeeper marauder pilot.
Officer Yal Henta
A Prowler pilot, Aeryn's former friend from Crais' Command Carrier. Feels betrayed by Aeryn's desertion.
- Beleaguered Childhood Friend: Still with the Peacekeepers when Aeryn encounters her several years after deserting.
A Peacekeeper soldier from 300 cycles before the setting of the series, Daycon is considered one of the greatest military heroes for his actions on the Jocacean homeworld in fostering peace with the Venek Horde. In reality, as the crew discover during a Time Travel incident gone wrong, Daycon was the communications officer and sustenance preparer (cook) of the unit, and a Reluctant Hero to boot.
- I Just Want to Be Normal: His anxiety boils down to "I'm just the cook!"
A Leviathan science officer who tried to prevent Talyn's conception when Moya was still under Peacekeeper control. He installed the contraceptive device that D'argo later broke, and was a former lover to Aeryn.
- Defector from Decadence: Attempted this with Aeryn in the past. It didn't work out.
- The Smart Guy: Crais clearly didn't like him, but needed him for his expertise with Leviathans
- Reasonable Authority Figure: Continuing the trend of lower-ranking officers having their heads screwed on straighter than flag officers. Velorek abhors Crais and his methods, treats Pilot with respect, tries to give his predecessor as Moya's pilot every chance to fall in line, and is appalled at the risk Crais' secret project poses towards Moya.
- You Are Better Than You Think You Are: A firm belief of his towards Aeryn and Pilot. He encourages the latter to disobey his Elders and bond with a Leviathan earlier than instructed, all to see the stars. Its more apparent with Aeryn, where he desperately attempts to convince her to be more than just a Peacekeeper. Notably, he seems more impressed than angry when she betrays him as "no other Peacekeeper would have thought of it."
A Peacekeeper scientist with a specialization in Leviathans. Used by Scorpius to spy on Crais when the latter returns to the Command Carrier. She was Crais' former lover.
- Cruel to Be Kind: On the receiving end of this. A regretful Crais publicly backhands and denounces her as a spy so she won't be blamed for what he later does to the Command Carrier.
- The Smart Girl: A Leviathan scientist.
- The Mole: Was subjected to Scorpius' Aurora Chair and planted by him to keep tabs on Crais. Crosses into Reverse Mole, as she does tell Crais this and tries to help him however she can.
Crais's original first officer, before Braca. Crais killed her when she witnessed a message from High Command recalling Crais from his pursuit of Crichton.
- She Knows Too Much: She made sure no one else knew of High Command's recall orders. He thanked her by calmly stroking her face and then snapped her neck.
- Small Role, Big Impact: Her death at the hands of Crais ultimately instigates both his downfall and Scorpius taking command.
- Undying Loyalty: She was as loyal to Crais as Braca is to Scorpius, and she suffered for it.
Technical Staff and Scientific Advisors
A Peacekeeper technical specialist. Unlike the soldier caste, she saw little to no combat during her career and was instead utilized for maintenance and engineering tasks.
- Big Damn Heroes: Subverted, though not for lack of trying. She tries to save Crichton from Scorpius as they're escaping from the Gammak base, but her lack of combat experience kept her from maintaining covering fire, giving Scorpius the chance to retaliate, which ultimately killed her.
- Broken Bird
- Death of the Hypotenuse
- Kill the Cutie
- MookFace Turn: As a tech, however, she was one of Crais's Evil Minions rather a Mook.
- Reverse Mole: In "Nerve" and "The Hidden Memory," Gilina functions as this, sabotaging the Gammak base's surveillance systems to help Crichton and Chiana enter and escape.
- Star-Crossed Lovers: With Crichton. They got along great when she first appeared on the Zelbinian, but later on at the Gammak base, she doesn't take it well when he reveals that he's fallen for Aeryn since then.
- Wrench Wench: She's a tech, not a soldier like Aeryn. On the Zelbinian, she and Crichton worked together to get the defense screen working again.
A Peacekeeper scientist initially picked to be wormhole project leader, but he makes the mistake of being overconfident around Scorpius.
- Killed Offscreen: When ordered to fly through an unstable wormhole
- You Have Failed Me: He demanded that Scorpius begin the biological trials of the wormhole experiment before the current one degenerated. This led to one poor pilot becoming liquidated, so Scorpius punished him by making him fly the next trial.
A Peacekeeper scientist who eventually becomes the chief researcher of the Peacekeeper wormhole project.
- For Science!: Is in the Peacekeeper program solely for the chance to discover the means to control wormholes. He quickly pulls a HeelFace Turn when Crichton tells him the Peacekeepers' intentions for the technology.
- Heroic Sacrifice: Puts himself into the Aurora Chair to erase the wormhole knowledge from his mind. It's never made clear if he escaped the command carrier afterward or not.
One of the scientists working for Scorpius to develop and refine wormhole technology.
- Black Eyes of Evil: Subverted - Linfer is actually a member of a species known for their kindness to leviathans and is herself rather affable, simply working on Scorpius's project.
- Never My Fault: When yet another test pilot turns to meat gravy from entering a wormhole, Linfer insists the fault was in the pilot's failure to calibrate the shielding she designed rather that her shielding. She loses this when she starts to lose her cellular integrity.
- Punch-Clock Villain: Linfer, despite her pride, is a reasonable enough and ration scientist who seems to just work for the Peacekeeper rather than feeling any loyalty to their cause (which makes sense, as she is no Sebacean).
A Disruptor for the Peacekeeper Special Directorate undercover on the Royal Planet in the Breakaway Colonies.
- Action Girl: Reveals her true identity to Crichton in the most ass-kicking manner possible by effortlessly slaughtering a group of assassins that had just thoroughly kicked his ass.
- Always Chaotic Evil: Thoroughly averts this where the Peacekeepers are concerned. She's certainly ruthless at her job and leaves no doubt that she's willing to kill anyone who jeopardizes her mission, (she attacks Scorpius to rescue Crichton's severed head from him) but she expresses genuine concern for the lives at risk should she fail. Jenavian is one of the first characters in the series to show that the Peacekeepers do indeed have an altruistic purpose.
- Blade Below the Shoulder: Has a stiletto hidden in her wrist, which she can extend Wolverine-style.
- Deadpan Snarker: Jena gets quite a few choice lines.
- Ensemble Dark Horse: Despite only appearing in three episodes, Jenavian is one of the most popular characters in the series, and actress Bianca Chiminello is in high demand at any gathering for the series.
- First-Name Basis: One of the few characters to regularly address Crichton by his first name.
- Girl of the Week: To Crichton.
- Good Is Not Nice: While she may be the first genuinely good Peacekeeper agent on the series, she's nonetheless utterly ruthless and willing to kill anyone who jeopardizes her mission to prevent the Breakaway Colonies from becoming a pretext to war between the Scarrans and Peacekeepers.
- I Did What I Had to Do: Jenavian's orders are to preserve the neutrality of the Breakaway Colonies and prevent Clavor from aligning them with the Scarrans, which Scorpius indicates would provoke an all-out war. She's willing to take whatever measures are necessary to see this through, no matter how ugly.
- The Mole: Jenavian is introduced as Prince Clavor's fiance. In truth she's a Peacekeeper Disruptor infiltrated into the royal court by Special Directorate to protect the neutrality of the Breakaway Colonies by preventing Clavor from succeeding to the throne and allying with the Scarrans.
- Ship Sinking: While attracted to Crichton, and they do spend the night together, he ultimately rejects her, though they part on amicable terms (not that it would work out given her position with the Peacekeepers).
- Ship Tease: Jena and Crichton spend a night together and she even expresses an interest in starting an ongoing relationship with him.
- Token Good Teammate: For the Peacekeepers at the time she's introduced. Jenavian is the first we meet in the series who genuinely takes their mission to protect others seriously not as a means to expanding their own power, but out of concern for the hundreds of millions of innocent lives that may be put at risk should she fail.
Aeryn's mother, head of a special unit sent to recapture Talyn.
- Arch-Enemy: To Aeryn.
- Ax-Crazy: A result of her life being destroyed and being forced by the Peacekeepers to kill her lover and anyone else they wanted eliminated.
- Badass Long Coat: In "The Choice."
- Crazy-Prepared: Left a knife and a supply of stimulant concealed inside her wrist in case she was ever captured.
- Disney Villain Death
- Femme Fatalons: Used for cutting her wrist open to retrieve the knife.
- Good Scars, Evil Scars: The left side of her head has been badly scarred, and she's missing her left ear.
- Heartbroken Badass: Puts up a wall to hide a Hidden Heart of Gold, but deep down, she regrets that she had to kill Talyn and that she destroyed her relationship with daughter.
- It Gets Easier: As she says to Aeryn:"I wasn't an assassin until I killed your father. I was a pilot. I was bred to be a pilot, but they made me kill again and again. And finally, I stopped caring."
- Luke, I Am Your Father: Xhalax decided to reveal the fact that she was Aeryn's mother many years before the series began; she also informed Aeryn that she was conceived not to provide the Peacekeepers with another expendable soldier, but out of love.
- Mysterious Mercenary Pursuer: Xhalax was this up until Crais revealed who was leading the Retrieval Squad.
- Sadistic Choice: Peacekeeper Command discovered her Luke, I Am Your Father moment and were outraged. They ordered her to kill either Aeryn or Aeryn's father Talyn Lyczac as a way of redeeming herself. Xhalax chose Talyn.
- Villainous Breakdown: After watching the hologram recording of her first meeting with Aeryn, Xhalax throws a temper tantrum which continues until the end of the episode.
- You Keep Telling Yourself That: She insists that Aeryn's pain in "The Choice" has easied her own. Aeryn doesn't buy it and is proven right.
