Babylon 5/Tropes I to P

This page covers tropes found in Babylon 5. Tropes beginning with letters A-H can be found at Babylon 5/Tropes A to H and tropes beginning with letters Q-Z can be found at Babylon 5/Tropes Q to Z. Subjective tropes go to the YMMV page.

I

 * I Am Legion: The Vindrizis' human hosts communicate this by Finishing Each Other's Sentences.
 * I Can't Believe It's Not Heroin!: Even small amounts of alcohol can turn a Minbari into a violent psychotic.
 * In a late season 5 episode Sheridan references the effect alcohol has on Minbari. Emperor Londo is visiting the new Alliance HQ on Minbar and asks about alcohol, but there is none, so he can't.
 * Icarus Allusion: The scientific expedition that reawoke the Shadows by poking into Things Man Was Not Meant to Know was called the "Icarus expedition", after the ship on which it traveled.
 * I Did What I Had to Do: By the end of the series, you would be hard pressed to find any main character who did not end up compromising their morals for what they at least thought was the greater good.
 * Of particular note is Sheridan, Lyta, and Doctor Franklin using  to disable a fleet of ships in orbit over  . They used thirty innocent people, knowing the chance of their deaths were high, in order to save thousands. Nobody is happy about it.
 * I Don't Like the Sound of That Place: The Shadow homeworld, Z'ha'dum, roughly translates as "Death of the future".
 * I Gave My Word: When offered a chance to surrender or flee from the Earthforce ships advancing on the station, Sheridan refuses, having made a vow to Delenn that he would "draw a line" against the darkness.
 * IKEA Weaponry: Londo has an IKEA PPG which he ends up not using to assassinate G'Kar in "Midnight On The Firing Line".
 * "I Know You're in There Somewhere" Fight: Subverted in second-season episode "Divided Loyalties", where an appeal to the true personality fails entirely.
 * I Know You're Watching Me:
 * Morden almost seems to predict the moment when Sheridan, under duress, decides to release him from custody. When Sheridan turns to face the security monitor, Morden is grinning straight at him.
 * In the fifth season of Babylon 5, the telepath Lyta Alexander can sense video surveillance. Sheridan doesn't believe it until Captain Lochley asks him to switch cameras, and Lyta shifts her gaze accordingly.
 * I Need a Freaking Drink: You would, too, if you had to deal with what happens on this station.
 * Played for Laughs in one episode when Sheridan is explaining a vexing situation he's about to confront. When Ivanova asks if he needs anything, Sheridan responds "A gun, two bullets, and a bottle of whiskey."
 * And Played for Drama when Garibaldi falls off the wagon and starts drinking again.
 * Insecure Love Interest: Lennier takes four and a half seasons to admit that he's in love with Delenn.
 * It Works Better with Bullets: Works better with the power cell, rather. Sheridan, fed up with an ongoing argument with no end in sight, puts his sidearm in the hands of the B-Plot-antagonist-of-the-week and offers to let them shoot him if they want. They back down. Sheridan later reveals to an apoplectic Ivanova that he removed the power cell before handing his weapon over.
 * I Warned You: Delenn's righteously indignant speech before the Grey Council ("Severed Dreams").
 * I Will Only Slow You Down: Zathras gets pinned by a fallen pole in "Babylon Squared", and tells Sinclair to leave him..
 * I Will Punish Your Friend for Your Failure: Following the re-enslavement of the Narn homeworld by the Centarui, the decree is passed that any attack on a Centauri citizen will be met with the deaths of 500 Narns, including the perpetrator's own family.
 * I'll Pretend I Didn't Hear That: When G'kar begins smuggling weapons through B5, Garibaldi quickly catches on. In exchange for G'Kar fessing up and promising to move his hardware off-station, Garibaldi tacitly gives him a lead on an alternate (and much safer) route.
 * I'm Going for a Closer Look: Very bad idea upon encountering a Shadow vessel or most unidentified craft.
 * 's Famous Last Words.
 * I'm Standing Right Here: Unsure of whether Ivanova is hitting on him or not, Corwin turns up at his quarts with some (very pricey) synthetic roses. Quickly realizing his mistake, he claims to have found them lying outside her door. Amused, Ivanova remarks that whoever bought those roses "must be a real dope." Corwin, now deflated, is inclined to agree with her.
 * Ice Cream Koan: The Vorlon language seems to consist mostly of these. G'kar throws them out sometimes when disciples keep asking questions he has already explained he doesn't have an answer for and doesn't think anyone does.
 * If I Wanted You Dead...: Na'Toth's response when G'Kar accuses her of being an assassin sent to kill him.
 * If You're So Evil Eat This Kitten: Sinclair is put in this situation in "The War Prayer" when he pretends sympathy with an earth-supremacist group so he can find out what they're up to.
 * Immortality Immorality: Jha'Dur, a Mengele-style genocidal scientist, gets the last laugh when Earthforce grants her a pardon in exchange for her longevity serum..
 * In the Hood: Delenn, whilst meeting with Marcus at his favorite tavern ("Ceremonies of Light and Dark").
 * Incendiary Exponent: how Minbari decided caste dominance in the old days.
 * Incoming Ham: MEEEEESter GariBALDi!
 * G'Kar got a far share of these as well. He had a tendency to announce his presence in a scene by shouting the name of the person he wanted to speak to from across the room.
 * Also Draal, especially after bonding with the Great Machine. He liked to do a sort of reverse Cheshire Cat; making some bombastic statement a moment before appearing as a hologram.
 * Incredibly Obvious Bomb: In "The Fall of Night",
 * Incurable Cough of Death: Duncan ("Exogenesis")..
 * Informed Judaism (Ivanova). In the episodes where it comes up, it's made fairly clear that she isn't exactly a practicing Jew.
 * Innocuously Important Episode:
 * The thirteenth episode "Signs and Portents" -- which is Exactly What It Says on the Tin. The episode's "A" plot is some fairly standard and unimportant thing involving Raiders [space pirates] and a Centauri artifact called The Eye. The "B" plot, involving the first appearance of the enigmatic Mr Morden and the question "What do you want?", turns out to be incredibly important and crucial to the rest of the series -- but the episode's retrospective importance only kicks in at the first season finale.
 * Its importance was lampshaded by the fact that the entire first season was also named "Signs and Portents" (though a casual viewer wouldn't know this - the season titles only appeared on fan sites.) "Portents", of course, are hints about future events.
 * "Midnight on the Firing Line'': appeared rather lackluster when it first aired, but to which the show kept referring throughout many of its best moments over the rest of its run.
 * Insectoid Aliens: The Gaim. Also, the species to which n'grath belongs. The Shadows might count, too.
 * Insistent Terminology: "Food plan" in the Diet Episode.
 * Institutional Apparel: As seen in "The War Prayer" and "The Quality of Mercy", prisoners wear grey jumpsuits with black arrows on them. But they're futuristic arrows!
 * Internal Affairs: In the episode "Eyes", the title refers to the nickname of Earthforce Internal Affairs. The "Eyes" have a generally bad reputation, as usual for this trope, and the particular one in this episode proves to be bending the rules a lot in pursuit of a personal grudge.
 * Internal Reformist: During late stages of the arc revolving around trying to depose President Clarke, we meet one or two of these.
 * First is William Edgers, Garibaldi's new boss and a powerful corporate executive. Edgers feels that Sheridan's rebellion does more harm than good, since it both gives Earth an external threat to focus on and allows Clarke to consolidate his power and use Martial Law to crack down on any dissent and reform. Edgers is part of a group of powerful behind the scenes players, and his plan is to bring down Psi Corps, since it's the main base of Clarke's power, knowing that without it Clarke will soon fall.
 * A slightly more orthodox example is Susanna Luchenko, the head of the Russian Consortium. Like Edgers, she appears to have been part of a group that wanted to take Clarke down, only consisting of politicians instead of businessmen this time. She grudgingly admits that what Sheridan did was probably the right thing, but he "[d]id it in a way that was inconvenient" because it resulted in a Civil War that damaged much of the Earth Force Fleet, and showed instability and vulnerability to alien governments.
 * Iron Lady: Ivanova has touches of this.
 * Ironic Echo
 * Bester and Sheridan have an exchange of these in one episode with "It's an unperfect world."
 * Irony: Delenn gives Garibaldi the "Blind and Toothless" speech when he espouses the death penalty ("Eye for an Eye"), despite she herself having ordered a genocide over the death of one man in particular. Trust Garibaldi to come up with the perfect answer; 'No, only the bad guys.'
 * Dramatic Irony: Delenn tells her fellow Religious Caste leaders how brutal and unpredictable the Warrior Caste is, how her Caste would never turn on their own, and how people from her Caste are all wiser and better than them. This is after these guys had, after incomplete information, attached waste exhaust to the environmental systems to kill everyone on the ship so they wouldn't surrender.
 * From "And the Rock Cried Out, No Hiding Place": Londo got every feature of where Na'Toth was imprisoned right except the planet. One wonders if he was thinking about this in "A Tragedy of Telepaths". It would be interesting to know if Vir ever found out either.
 * ISO Standard Human Spaceship: the Novae, their successor Omegas and the Warlocks are quite boxy and ungainly, and painted in various shades of grey. The Hyperions are a bit more rounded and brightly colored, but are produced by a different military contractor than the Omegas and Novas.
 * It's All Junk: In "The War Prayer", Ivanova bins the gift she received from the boyfriend she's just broken up with.
 * It's All My Fault: John Sheridan blames himself for his wife Anna's death, which happened on a scientific expedition she joined in place of a holiday they'd planned and then he'd postponed because of work commitments. When he eventually admits this to his sister, who was also his wife's best friend, she tells him that Anna had already decided to join the expedition, and if he hadn't asked her to postpone the holiday, she'd have asked him.
 * It Is Pronounced "Tro-PAY": In the Documentary Episode And Now For A Word, Cynthia Torqueman consistently pronounces Commander Ivanova's name wrong. While Ivanova visibly reacts, she doesn't comment on it. Of course, Torqueman might have done it intentionally to try and get a rise out of her interviewee. Especially since in real life, reporters are usually careful to check the pronunciation of a person's name.
 * It Is Pronounced "Tro-PAY": In the Documentary Episode And Now For A Word, Cynthia Torqueman consistently pronounces Commander Ivanova's name wrong. While Ivanova visibly reacts, she doesn't comment on it. Of course, Torqueman might have done it intentionally to try and get a rise out of her interviewee. Especially since in real life, reporters are usually careful to check the pronunciation of a person's name.

J
"Bester: "...spark misleading hunches...""
 * Jack Bauer Interrogation Technique:
 * Just another day at the office for Alfred Bester.
 * Subverted with Garabaldi, who is really good at convincing people he's willing to resort to these. However, when his boss actually goes ahead with it, Garibaldi takes him aside and explains how if that happens again, he can find a new security chief.
 * Jedi Mind Trick: Alluded to by Psi-Cop Alfred Bester while he and his team are chasing a runaway Telepath.


 * Jerkass Facade: Sinclair puts this on in The War Prayer to earn Malcolm Biggs' trust and to catch him and his allies off guard.
 * Jerkass Has a Point: Garibaldi has an argument with a post office worker who charges 100 credits to pay for a package that got delivered. Now the worker points out that the price hike is due to Yet most of the B-Plot was following Garibaldi trying to avoid paying the price, eventually resorting to extortion to get his money back. Because the guy dared to do his job (Or heck, go beyond his duty considering he's trying to maintain the service despite the consequences).
 * The Jester: Subverted: One episode shows a jester in Cartagia's court mocking him behind his back. Cartagia turns around to see this, and laughs it off. He then has the jester killed.
 * Jigsaw Puzzle Plot: One of the classics.
 * Just Following Orders:
 * This trope is the excuse given by many Earthforce officers who obey Clark's illegal orders.
 * Doctor Franklin explicitly does not. During the Earth/Minbari war, he was ordered to turn over his notes on Minbari anatomy so that the military can create a biological weapon. He refuses, stating that under military law he has no duty to obey an order if it would violate his conscience. The military locks him up and tears his house and office apart looking for some remnant of those notes. He was just Genre Savvy enough to have destroyed them in advance, knowing in times of war, military law is "Do What We Say And MAYBE We Won't Kill You."

K
"Garibaldi: Like you said, I never start a conversation unless I know where it's going, but I always leave a little room for someone to disappoint me."
 * Kangaroo Court: In the episode "Rising Star" President Susanna Luchenko tells Sheridan that the officers at his court-martial will be from the 'shoot him' side. He has no chance of being found innocent and the trial will be solely for the sake of reinforcing political control over the military. Of course, this arrangement was so that Sheridan would take the other choice being offered: He resigns from Earth Force, allowing the government to re-consolidate without his polarizing and destabilizing presence. Long story short, his career in Earth Force is over one way or another.
 * Karma Houdini:
 * Dan Randall, the ISN news reporter from "The Illusion of Truth". Yes, Clark's administration all got snapped by Sheridan's comeback tour, but it would've been nice to see that guy crucified.
 * Alfred Bester, more or less. (Much less in the novels. )
 * Crusade, the spin-off series, showed that at least one member of Nightwatch was one of these. It isn't directly stated, but it's the same actor, with the same name, and he states that he knows a thing or too about surviving changes in governments.
 * King in the Mountain: Played with in "A Late Delivery From Avalon".
 * Klingon Promotion / Make It Look Like an Accident: Clark ascends to the Presidency after his predecessor dies in a suspicious explosion.
 * Knight in Sour Armor: Marcus Cole. Garibaldi even more so.


 * Knight Templar:
 * Byron's followers.
 * William Edgars sets himself up as this, though he imagines himself a Well-Intentioned Extremist.
 * Almost every side has at least a few.

L
"Ivanova: All my life I've fought against imperialism. Now I'm the expanding Russian frontier! Franklin: Yes, but with very nice borders."
 * Land of One City: Babylon Five is this for much of the show.
 * Lampshaded Double Entendre:
 * Franklin to Ivanova, after the latter balks at her newly-prescribed diet.

"Franklin: Look, I was just helping her out of a difficult situation, that's all. Marcus: Fifty credits says that's not all she wants you to help her out of."
 * Marcus notices that the leader of the Martian resistance movement has taken an interest in Dr. Franklin.

""(You) are both damned.""
 * La Résistance:
 * An "Underground Railroad" of rogue telepaths who seek to elude Psi Corps. A handful of doctors (including Dr. Franklin) first established the railroad in response to stories of humans rights abuses being committed on telepaths.
 * One of Earthforce's Joint Chiefs, William Hague, organizes a mutiny against President's Clark's regime. Ultimately, Hague's leadership over the resistance passes down to Sheridan.
 * The Narn resistance is organized by cells both on and off-world, smuggling weapons, food, and other resources. Ex-Ambassador G'Kar is the most prominent figure in this movement, despite continuous Centauri efforts to rub him out. Remnants of the Narn fleet eventually join the struggle against the Shadows led by John Sheridan.
 * The Mars Resistance, formed by people who want Mars to be independent of Earth. They are little more than a terrorist organization in the first season, but by the fourth season Babylon 5 is actively working with them to topple the Clark regime.
 * Babylon 5 itself becomes this, especially during the Fourth Season.
 * Large Ham:
 * G'Kar.
 * Londo.
 * DRAAL.
 * After he bonds with the Machine. The older, pre-Machine version of him (played by the same actor as Brother Theo) is more low-key.
 * "King Arthur" is an expansive talker, as can be expected. Also, he's played by veteran ham Michael York.
 * Laser Hallway: Of the lethal variety. Encountered by Sinclair and Invanova in "A Voice In The Wilderness".
 * Last-Minute Reprieve: Used a few times throughout the series.
 * Last of Her Kind: Deathwalker. Her stated goal was to give away her final discovery as penance for what she and her people did during the Dilgar War.
 * Last Words: As Emperor Turhan lies on his deathbed, Londo and Refa inform him that Centauri forces have resumed war with the Narn, and ask for his blessing. Turhan whispers something into Londo's ear, which Londo reports as: "Continue. Take my people back to the stars". Out in the hallway, a sly Refa asks Londo what the Emperor really said. It was,

"Drazi customer: Can you gift-wrap this for me?"
 * Latex Perfection: Played for laughs in "There the Honor Lies" when Ivanova pays a visit to B5's gift shop. Suddenly, all of the human/alien customers remove their 'masks', sending her fleeing in terror.

"Sheridan: "...willing to fight for it, willing to..." (he can't bring himself to say "die" in front of the very man he is ordering to his death.)"
 * Leeroy Jenkins: The Narn are a whole species of these.
 * Possibly the best example of this is when Earthforce is boarding Babylon 5 to try and get the station back from Sheridan. Garibaldi and a large percentage of his security team (augmented by recently-recuited Narn soldiers) move in to where the breaching party will enter the station. As Garibaldi and the Humans begin digging in to set up a kill zone, the Narn just rush on ahead, forcing the humans to chase after them.
 * Left Hanging: So...how 'bout those Human Popsicle telepaths they rescued from the Shadows?
 * Lethally Expensive: Invoked. Sheridan orders the rangers to leak some information to the Shadows. However he is concerned that they won't believe it unless someone was:

"Lennier: I'm trying to keep a promise. By breaking a promise. I was told not to mention this to anyone in the chain of command. You were not mentioned by name but that is implicit. However, by telling you, the captain need not find out about it and I will not have broken the promise. Marcus: I'm in awe, Lennier. The way you can take a simple proposition and turn it inside out so that it says what you want it to say rather than what it actually says. Does this come naturally or did you attend some sort of ... martial arts class for the philosophically inclined?"
 * Letter Motif
 * Letting Her Hair Down:
 * Minor example in "Survivors". The head of the Presidential security detail starts out very uptight, with a hairstyle to match. In the final scene, she's more friendly, and also wearing her hair down. (The change in hairstyle is justified by that being the first scene where she's off-duty, but it's still a trope because it coincides with her increased friendliness, which is not just because she's off-duty.)
 * Ivanova usually has her hair scraped back severely while working and in hard-ass executive officer mode, but wears it down when off-duty and with close friends, when her genuine friendly persona comes through.
 * Life Energy: The alien machine from The Quality of Mercy can transfer this from one person to another.
 * Like an Old Married Couple: In the commentary for "The Deconstruction of Falling Stars," JMS mentions that during the filming of the Londo/G'Kar scenes an extra actually asked "How long have they been married?" after the scene was finished. Their bickering was lampshaded throughout the series, and in "A View From the Gallery" a character within the series wondered how long they had been together after he saw them arguing.
 * Characters were joking about Londo and G'Kar being married way back in the first season, back when G'Kar was clearly a bad guy and Londo was clearly a good guy.
 * Literary Allusion Title
 * The Bible
 * Movie "In The Beginning" (Genesis 1:1)
 * "A Voice in the Wilderness"
 * "Revelations"
 * "Passing Through Gethsemane"
 * William Shakespeare
 * "The Quality of Mercy" (The Merchant of Venice IV.i)
 * "The Paragon of Animals" (Hamlet II.ii)
 * "Wheel of Fire" (This was also the title for the entire fifth season.) (King Lear IV.vii)
 * Mark Twain
 * "The War Prayer", after the essay of the same name
 * Littlest Cancer Patient: Subverted twice. See Anyone Can Die.
 * Living Ship: Vorlon ships are shown to be both sentient and organic. Kosh also shares a telepathic link with his vessel.
 * Shadow ships also appear to be at least partly organic,
 * Loan Shark: Desmond "Deuce" Modichenko ("Grail").
 * Lock and Load Montage: Babylon 5's defense grid.
 * Locked in a Room: Subverted in "Convictions".
 * Loophole Abuse:
 * A Narn warship that escaped the destruction of its homeworld jumps into Babylon 5 space, requesting sanctuary. Unfortunately, a representative from Earthgov announces that Earth is prepared to sign a non-aggression treaty with the Centarui, something which virtually translates to appeasement. A Centauri battlecruiser arrives, demanding custody of the Narn ship. Sheridan refuses, stating that the treaty isn't finalized in the senate yet, so therefore he can grant asylum to whoever the hell he wants (The Centauri disagree).
 * When Delenn's life was in danger from Neroon but she did not wish Sheridan to know, she forbids Lennier from telling him. He opts to ask Marcus for help. His reasoning is:


 * Loss of Identity: Death Of Personality.
 * Lost Tribe: The unnamed alien race of Epsilon III.
 * Loud of War: As punishment for trifling with Elric, the computers in Londo's quarters are reprogrammed to continually blare "Narn opera".
 * Lower Deck Episode: "A View from the Gallery"

M
"Sheridan: "How do I know you're the same Vorlon? Inside that encounter suit, you could be anyone." Kosh: "I have always been here." Sheridan: "Oh yeah? You said that about me, too." Kosh: "Yes." Sheridan: "I really hate it when you do that." Kosh: "Good.""
 * MacGuffin Escort Mission: The Mars Resistance agent handing his parcel down to Lyta ("Divided Loyalties").
 * Maintain the Lie: Averted; "The War Prayer" has the set-up -- Vir has been telling his relatives that he's the Centauri ambassador on Babylon 5, and then one of them comes to visit -- but instead of trying to Maintain The Lie, Vir admits the truth straight away, accepts a bit of ribbing, and they move on to spending the rest of the episode trying to sort out the problem the relative came to ask his help with.
 * Malaproper: Delenn lacks intimate knowledge of a few select human phrases.
 * Mama Bear: Laura Rosen, already dying from lake's Syndrome, donates her life force to patients who visit her clinic in Downbelow. When Karl Mueller threatens her daughter, Rosen kills him by sapping away his life, instead. Though cleared of all charges, Rosen is deeply shaken by the experience, having violating her oath as a doctor.
 * Man Hug: Exchanged between Keffer and his newfound Marine Corps buddies, shortly before their doomed mission on Aknor.
 * Man in the Machine:
 * Varn, a mysterious alien who governs the "Great Machine" of Epsilon III. When Varn's life starts to fade, Delenn's mentor Draal agrees to take over his duties.
 * Shadow ships require living being at their core; the two merge, becoming one entity. If the pilot isn't properly prepared (i.e., a moronic Earthgov test monkey), the result is a confused, insane ship.
 * A Man Is Not a Virgin: Except for Marcus, who is still qualified to chase unicorns.
 * Sort of. See the page for details.
 * Manipulative Bastard: Lord Antono Refa, Morden.
 * Mathematician's Answer:
 * Everything that Kosh says is not exactly helpful:

"Sheridan: Well, as answers go, short, to the point, utterly useless and totally consistent with what I've come to expect from a Vorlon. Kosh: Good."
 * Sheridan even lampshades this.

"Ivanova: Babylon 5, our last best hope to make a quick buck!"
 * The Drakh do the same in season 4: "Drakh? Is that your name or your species?" "Yes."
 * Even J. Michael Straczynski himself can't resist this trope. (warning: link contains spoilers) "Was Kosh's line about Sheridan going to Z'ha'dum a warning or a threat?" "Yes." GAH!!
 * Mayfly-December Romance: Sheridan and Delenn.
 * Meaningful Echo:
 * "Hold the line."
 * King Arthur's line about resurfacing in the 23rd century "because I am most needed here and now" is analogous to Delenn and Sheridan being "the right people, in the right place, at the right time".
 * Meaningful Name: Delenn means "Gray Traveler" which doubles as a Shout-Out to Lord of the Rings, given that Gandalf's Elven name is Mithrandir, which means "Gray Wanderer"
 * Timov Mollari, Londo's wife, represents Famine and she is constantly remembering the lush happy dreams of a good future with Londo as she lives through a barren, love-less marriage. Mariel has an angelic sound and
 * Mentor Archetype:
 * Aldous Gajic to "Jinxo" in the first season episode "Grail". As well as several other characters.
 * Kosh Naranek
 * G'kar becomes this to the entire Narn race in season 5. Although he soon becomes frustrated that most of the Narn who come to the station to listen to him end up Completely Missing the Point.
 * Byron to his followers.
 * The Merch: Lampshaded when Sheridan proposes opening a gift shop on-board the station. Doubles as a thinly-veiled Take That toward the Trek franchise (see "Dueling Shows").

"Ivanova: (in Minbari) Engines at full... high power. Hatrack ratcatcher to port weapons... brickbat lingerie."
 * Messianic Archetype:
 * Byron.
 * Sheridan, Sinclair and Delenn, all in their own ways.
 * G'kar after his spiritual enlightenment.
 * Microts: Time is measured by "cycles", or rotations of the station; the obvious reason being that Earth, Narn, and Minbar have varying day-to-night clocks. Many worlds also use the term to refer to their solar years. The actual definition of a "cycle" varies Depending on the Writer. In "TKO", three cycles is something like three days; in "Grail" (the very next episode), three hundred cycles is something like three days. By Season Three, there is a notable changeover to "standard hours", presumably because it's less confusing.
 * A few mentions were made in show of there being 36 hours in a (presumably Babylon 5) day (maintain a 36 hour watch, we're open 36 hours a day, etc).
 * Subverted with years, 1000 of which have passed since the last Shadow war. Which planet's years are never mentioned.
 * In one episode, this causes some confusion, when it turns out that while a Cycle on B5 is a relatively short period of time, a "Cycle" on the Drazi homeworld is a whole year. Presumably due to something being Lost in Translation.
 * Mid-Season Upgrade: About midway through the second season, Babylon 5's defense grid is given substantial upgrades, in response to increasing tensions in the region. The General overseeing the upgrades even goes on to speculate that the station could now take on a starship in a fight.
 * A Mind Is a Terrible Thing to Read: Pretty much every teep.
 * Mind Manipulation, such as Mind Probe and Mind Rape:
 * Something PsiCop Mr. Bester was very fond of.
 * The power granted by the telepathic drug "Dust" is specifically described as Mind Rape in the episode (season three's "Dust to Dust") in which it's a major plot element.
 * And it was inverted in the same episode. A Dust user mind rapes the first person he runs into. And ends up reliving a severe trauma experienced previously by his victim: They got caught in a landslide, causing him to scream over and over again that the mountain fell on him.
 * Happens to Sheridan and Delenn, more or less by design, somewhat by consent, during the final battle.
 * Actully Bester, while quite willing to mind probe, wasn't one to mind rape unless there were telepath lives at stake. The man did have some standards.
 * Even the heroes used it on one noteworthy occasion, attempting to prevent a murder.
 * Mind Over Manners: The less evil telepaths, most of the time, follow the rule about not scanning someone against their will. Mostly.
 * Mismatched Eyes:
 * Mistress and Servant Boy: Delenn and Lennier
 * Modest Royalty:
 * Emperor Turhan. An elderly, ill man near the end of his life, he was more or less bald human-ish with no hair fan to speak of. He owned a rather impressive wig, but refused to take it with him during his official visit to Babylon 5, saying that the trappings of status were no longer important to him.
 * His successor Cartagia, for all his insanity, has a distinctly subdued sense of taste for a Centauri. He even chooses to wear his hair short even though traditionally, the size of a male Centauri's hair fan indicated his status. Only a quasi-example, since Cartagia explains to Londo that the reason he worse his hair shorter was so that he could go among the "lower classes" quite easily, and implied that it enabled him to indulge in... less savoury pleasures.
 * The Mole:, Garibaldi's trusted aide. After the latter uncovers a plot to kill President Santiago,   repays his trust by shooting him In the Back.
 * Money, Dear Boy: Why Legend Of The Rangers was made.
 * Moral Myopia:
 * Minbari were all pissy over Sheridan's nuking of the Blackstar despite their own policy of taking no prisoners and leaving no combatant survivors [that they know of].
 * Vir's arranged wife feels Narns are a brutal race that needs culling and has participated in multiple atrocities.
 * Bester feels absolutely no remorse about killing mundanes and is less than sympathetic toward teeps that are not Corps.
 * The Narn in the first season are presented as themselves being ruthless imperialists, as well as being willing to do arms deals with anyone including pirates and war criminals. Their chief complaint about the Centauri seems to boil down to the fact that it happened to them.
 * Sheridan  seems a little jarring when you consider that it was probably filled with non-combatants.
 * Mordor: Z'ha'dum. It even has a Great Eye,
 * Morality Pet: Vir fills this role for Londo on quite a regular basis. Indeed he's stayed Londo's hand on more than one occoaision, and Londo is at his worst when Vir is absent.
 * Mugging the Monster: The Streib. "Their last expedition was into Minbari space. We tracked them back to their homeworld. And made sure they understood the depth of their mistake." Given the final fate of the Streib vessel one might argue that venturing into human space was not necessarily one of their best ideas either.
 * Multi Boobage: In "TKO", Garibaldi and Walker Smith reminisce about a place they used to frequent where the waitresses had three [meaningful hand gesture].
 * Murder the Hypotenuse:
 * The trope is then subverted moments later, as he regrets his decision and goes back.
 * My Future Self and Me: In "Babylon Squared",  glimpses his future self, but does not recognize himself due to his counterpart's hazard suit.
 * My Country, Right or Wrong: General Lefcourt and Captain Lochley, both of whom consider it immoral for the military to dictate government policy, whether they like President Clark's decisions or not.
 * Londo starts off this way. Though he has his doubts here and there during the war with the Narn, he still remains loyal to his people. By the end of the war, he's realized what a big mistake it was to enlist the help of Morden and his "associates," but by this point he's so firmly entrenched in everything that happened that he goes along with it mostly to preserve his own skin.
 * My God, What Have I Done?:
 * A truly heartbreaking example in "The Coming of Shadows" when
 * Another being during the Earth-Minbari War when Delenn receives Dukhat's last message.
 * Londo again,
 * Peter Jurasik should have gotten an award for that scene. He doesn't speak a word, and you only see him on screen for a few moments, but the look on his face says it all.
 * My Hovercraft Is Full of Eels: Ivanova speaking Minbari:

"Lorien: "Ahel" mean "continuous fire" in Minbari..."
 * "Ah, hell..."


 * My Rule Fu Is Stronger Than Yours: Commander Sinclair's rule fu is strong. Probably his most triumphant moment is in the episode "By Any Means Necessary".
 * Sheridan gets a chance to exercise this as well. In one episode Earthforce attempts to charge him rent on his quarters. He refuses to back down, even after they change the locks. Eventually, he resolves the situation by charging his new rent against the station's military budget, on the grounds that he won't be in any condition to fight unless he's had a good night's sleep in his own bed.
 * My Species Doth Protest Too Much: There are exceptions to every hat race. In the RPG, even the Dilgar had a small, hidden colony who did not partake in their species' predilection for crimes against sapience.
 * Mysterious Backer: The orderly Vorlons are nominally on the side of the protagonists, but they're far from trustworthy saints.
 * Myth Arc: Trope Codifier.

"Marcus: "You know, I used to think that it was awful that life was so unfair. Then I thought: Wouldn't it be much worse if life were fair and all the terrible things that happen to us come because we actually deserve them. So now, I take great comfort in the hostility and unfairness of the universe.""
 * Name's the Same: Narrowly averted. The Narn homeworld is not, in fact, named Narnia.
 * Napoleon Delusion: In "A Late Delivery from Avalon", we meet a nutty swordsman who is convinced that he is King Arthur. It turns out that he is in fact and is suffering from a serious case of Survivors Guilt. He is healed when "The Lady of the Lake" (Delenn) retrieves his "Excalibur" (an antique sword), symbolizing that.
 * National Weapon: The Minbari Denn'bok.
 * The Narn have a sword which, like the katana, cannot be sheathed until it has drawn blood.
 * Naughty Tentacles: Centauri have six prehensile phalli, 2-4 feet long. Their definition of "bases" (as in "getting to second base") is how many you get to put in.
 * They also come in handy for cheating at cards. Unless someone has a pitcher of ice-water handy.
 * A Nazi by Any Other Name: The Ikarrans in "Infection", who programmed their machines to "protect" their world by murdering anybody who is genetically "impure".
 * Near-Death Experience: experienced by Sheridan across "The Hour of the Wolf" and "Whatever Happened to Mr. Garibaldi?"
 * Neck Lift: Lennier to Marcus
 * Neglectful Precursors: An ongoing theme of the later seasons of the show, as well as many of the spinoffs, was the younger races stumbling across various nasty things left behind by.
 * Never Got to Say Goodbye:
 * John Sheridan has a monologue where he laments the fact that he was rushed the day of the last phone call with his wife Anna, and forgot to say "I love you" before she headed out on the expedition that claimed her life.
 * Ivanova has similar regrets regarding Marcus. Marcus however did get to say "I love you" to a dying Ivanova, leading to the touching yet funny line, "I thought: God really does have an English accent, just like in those old movies."
 * New Neo City: Numerous references to New Vegas, a Mars-based resort. When Babylon 5 first came online, New Vegas oddsmakers put the odds of Babylon 5 surviving at 200 to 1.
 * New Old Flame:
 * Ivanova's old boyfriend, Malcolm Biggs, in "The War Prayer". By the end of the episode, he's.
 * Talia's got two of them: Jason Ironheart ("Mind War"; ) and Matthew Stoner ("Soul Mates").
 * Elizabeth Lochley.
 * Nice Hat: The Inquisitor's dapper-looking top hat.
 * Garibaldi puts one on as part of his "excellent disguise" when doing some investigating with Franklin in Downbelow. G'Kar is shown wearing it in a later episode as part of an attempt to better understand Garibaldi while searching for him.
 * Nice Job Breaking It, Hero: Marcus spends the entirety of "Exogenesis" investigating the disappearance of his friend, Duncan, who has been taken over by a Puppeteer Parasite. It later turns out that Duncan was on death's door, and that the parasites, or rather, the symbiotes, cure their hosts of all disease. Marcus realizes his error, but too late for Duncan; the symbiote leaves his body to prove its intentions are benign. Duncan can never be recoupled with one again. Somewhat bittersweet example, though: Before being bonded, Duncan was content to spend his twilight years running a kiosk in the Zocalo and making very little money. After briefly sharing the memories of the symbiote, he has decided to spend his last years exploring the galaxy and seeing new things.
 * The crew finds a man suffering severe delusions, thinking he's King Arthur. Seems there's no shrinks on B5 as Dr Franklin then decides to immediately break the man's delusion by reminding him who he is . Of course it does not go rather well, as the man has a breakdown and goes catatonic. Thankfully he gets better.
 * Nietzsche Wannabe: Marcus Cole (although he's one of the good guys).

"Londo: Everybody's cute. Except me. But in purple, I'm stunning!"
 * Nightmare Sequence
 * Nobody Ever Complained Before: The Minbari Warrior Caste's traditional method of greeting in interstellar dealings is to approach the ship with gunports open but uncharged, as a sign of respect to the other race. Unfortunately, Minbari tech dwarfs human tech, so when they approached the human ship and scanned them, they didn't think to turn off their stealth tech, and likely didn't know their sensors would shut down the Earth ships jump drives. When the human captain saw a fleet of advanced ships coming at them, somehow knocking out their jump drives, stealth tech preventing them from getting any reading beyond their gunports are open, and no means of effectively communicating, he panicked, resulting in a genocidal war.
 * No Hero to His Valet: Played straight with Vir who is very loyal but is also very much aware of Londo's faults. Subverted with Lennier. Delenn is always a heroine to her valet and remains so even after Lennier learns of her darker side in Atonement, despite Delenn's fear's of his reaction.
 * No-Holds-Barred Beatdown:
 * Nom De Guerre: The leader of the Mars Resistance is known through the entire fourth season only as Number One. It isn't until near the end of the series that we finally learn her real name.
 * Non Sequitur Thud:
 * A truly epic example courtesy of a drunken Londo in "Parliament of Dreams".


 * "And he made a very satisfying thump when he hit the ground."
 * Noodle Incident: In "A Distant Star", an old friend of Sheridan's visits the station. During dinner with the officers, Sheridan starts to tell an embarrassing story about him, and he retaliates with three words: "July 12th, 2253". Sheridan admits defeat, and neither story gets told.
 * Also, it seems that Ivanova and a smuggler did something that Ivanova is convinced lead to Garibaldi losing all his hair.
 * Nose Art: Many of the Starfuries have custom paint jobs on the wing just above the cockpits, including those flown by Mauve Shirts or Red Shirts. Ivanova has a black double-headed eagle with a red star superimposed, Garibaldi has a yellow and orange tigerstripe pattern, and Sheridan has the entire top wing of his fighter decorated in a tiger motif, complete with face and claw marks.
 * Sheridan takes it a step farther. When he launches his military campaign, he has the Babylon 5 crest painted on the hull of his flagship.
 * No-Paper Future: Lampshaded. A character in one episode complains that every time she's told we're entering a paper-free society, she gets three more forms to fill out.
 * No Such Thing as Alien Pop Culture: very, very much used throughout the series, to the point where when G'Kar, a Narn, asks the human Zach if the poster of Daffy Duck in Garibaldi's quarters is one of the human security chief's household Gods, Zach starts to explain, realizes it'll be more trouble than it's worth, and ends with, "You could say that." Though by the way G'Kar laughs at the explanation, it's clear he realizes that Zach's being facetious.
 * In Midnight on the Firing Line, the episode ends with Delenn sitting in Garibaldi's quarters with him watching Bugs Bunny cartoons. She seems faintly amused by it, but also very confused, apparently unsure what she should be doing. When Garibaldi offers her popcorn, she stares at the bowl for a moment before taking some, then turning back to the cartoon, asks Garibaldi to explain part of it to her.
 * In one episode, Vir and Lennier meet up at a bar. Lennier asks Vir what he's drinking, and Vir says it's a Shirley Temple. Lennier thinks about this for a second, and then says that while he's studied Earth's religions, he can't say he's ever heard of the Shirley Temple.
 * Not Actually the Ultimate Question: Repeatedly and vigorously deconstructed.
 * Not Listening to Me, Are You?:
 * In "Infection", an old mentor of Stephen Franklin's comes back with some alien artifacts that look like they're organic technology. Stephen gets so absorbed in the research that his friend tries to draw him out with the statement, "There's a Martian war machine parked outside; they'd like a word with you about the common cold."
 * Later in the series, Marcus Cole realizes that Ivanova isn't paying attention to his report: "There's always the threat of an attack by say, a giant space dragon, the kind that eats the sun once every thirty days. It's a nuisance, but what can you expect from reptiles? Did I mention that my nose is on fire, and that I have fifteen wild badgers living in my trousers?" (Ivanova finally looks at him, witheringly) "I'm sorry, would you prefer ferrets?"
 * Not So Different:
 * Londo and G'Kar realize this about halfway through the fourth season.
 * Sheridan and Delenn.
 * As is revealed to the characters and audience in the third and fourth seasons,.
 * The meeting between Delenn and "King Arthur" in "A Late Delivery from Avalon". Both had idealistic/mystical personalities. But their real similarity as that both bore heavily the knowledge that they had helped to start the Earth-Minbari war. Indeed "King Arthur" might actually have fired the shot that killed Delenn's beloved mentor. A very well done reconciliation scene.
 * Bester points out the similarities between himself and Garibaldi, though mainly just because it amused him to do so.
 * Not Cheating Unless You Get Caught: Upon learning that Lennier is a "master adept" at the laws of probability, Londo wrestles him into joining a card game. Unfortunately, the subtler points of playing Poker (like bluffing) are lost on Lennier. Londo then resorts to using his....erm, "appendage" (see "Naughty Tentacles") to re-shuffle the deck, getting busted in the process.
 * Nuclear Physics Goof: In "A Voice in the Wilderness", Ivanova speaks of a nuclear reactor "approaching critical mass", meaning that it's about to blow up. See the trope page for an explanation for why this is incorrect for nuclear fission reactors -- and then add to that the fact that Ivanova was talking about a nuclear fusion reactor, where the concept of "critical mass" doesn't apply at all.

O
"Garibaldi: I think I'm in love."
 * Obligatory Joke: Garibaldi to Dr. Franklin, after being revived from his coma: "What's up doc?"
 * For bonus points, it was established back in the first episode that Garibaldi is a fan of old Warner Bros cartoons.
 * Odd Friendship: Londo and G'kar, representing two races which had long been bitter enemies, grew into an Odd Friendship by the end of the series.
 * Offered the Crown
 * Oh Crap:
 * Oh God, Did She Just Hear That?:
 * In one episode of Babylon 5, resident telepath Talia Winters is explaining to someone that telepaths sometimes cannot avoid picking up particularly strong emotions and thoughts before entering a lift with Security Chief Garibaldi. After she explains this, Garibaldi, standing behind her, gives her the once over. Talia elbows Garibaldi in the gut before getting off.

"USENET: (on Passing Through Gethsemane) "The themes of faith and forgiveness were worthy of a theologian. Are you sure there isn't something you'd like to tell us?" JMS: Never shoot pool at a place called Pop's. Never eat food at a place called Mom's. The difference between horses and humans is that they're too smart to bet on what we'll do. And I have lost people. Too many people. Lost them to chance, violence, brutality beyond belief; I've seen all the senseless, ignoble acts of "god's noblest creature." And I am incapable of forgiving. My feelings are with G'Kar, hand sliced open, saying of the drops of blood flowing from that open wound, "How do you apologize to them?" "I can't." "Then I cannot forgive." As an atheist, I believe that all life is unspeakably precious, because it's only here for a brief moment, a flare against the dark, and then it's gone forever. No afterlives, no second chances, no backsies. So there can be nothing crueler than the abuse, destruction or wanton taking of a life. It is a crime no less than burning the Mona Lisa, for there is always just one of each. So I cannot forgive. Which makes the notion of writing a character who CAN forgive momentarily attractive...because it allows me to explore in great detail something of which I am utterly incapable. I cannot fly, so I would write of birds and starships and kites; I cannot play an instrument, so I would write of composers and dancers; and I cannot forgive, so I would write of priests and monks and Minbari...."
 * In another episode, Garibaldi is having an argument with the Psi Cop Bester, and as Garibaldi glares at him, Bester says, "Anatomically impossible, Mr. Garibaldi, but you're welcome to try, any time, any place."
 * Played with in one episode. Bester has been forced to take a drug which dulls his telepathic abilities. He and Garibaldi are interrogating an informant, and Bester at one point blurts out "he's lying." This causes the informant to break and tell them what they need to know. Garibaldi confronts Bester on this after the interview. Bester explains that he couldn't hear any of the man's thoughts, but the other guy didn't know that. And chances were good he was lying about something, so Bester merely played on the guy's guilty conscience.
 * Oh My Gods:
 * Londo says this in the Season 3 finale.
 * "In Valen's name!"
 * Old Friend
 * One Federation Limit: The Earth Alliance, the Minbari Federation, the Centauri Republic (which is actually a monarchy like the late Roman republic), the Narn Regime and the Vorlon Empire. Some races (like the Dilgar, Shadows, and Drakh) have no stated governmental body, while the others have ones only stated offhand or in the background material (Drazi Freehold, Brakiri Syndicracy, Abbai Matriarchate, Grome Autocracy, etc)
 * And all those miscellaneous governments could conveniently be lumped into the League of Unaligned Worlds.
 * One-Gender Race: The Pak'Ma'Ra ... sort of. The "hump" they have on their back is actually their mate, permanently bonded to them. Whether the hump is the male or the female is up for debate. In an online post, JMS stated that the hump is the female, but the official Babylon 5 Role Playing Game says that the hump is the male.
 * One Last Job: Refa pressuring Londo to enlist the Shadows in wiping out the Narn fleet. Londo, however, has grown fearful of his "associates" and warns Refa that that this is the last time he will call upon Morden.
 * One World Order: Earthgov, for all intents and purposes. Under Clark, the government institutes giving Psi Corps increased judicial powers, as well as creating a trio of agencies (The Ministries of Peace, Truth, and Information) to tilt the balance of power in his favor. Clark later dissolves the Earth senate, which he re-forms with many of his own people in place.
 * Earthgov is actually an alliance of most of the world's major powers, including Europe, America, Russia, Japan and others. It's also implied that many countries resisted the formation of Earthgov and that many of them are not equal members of the Earth Alliance, and yet the EA posits itself to be the unified representative of Humanity.
 * This holds true for the Minbari Federation and Centari Republic, as well.
 * Open-Heart Dentistry: Dr. Franklin can do everything from setting broken bones to major surgery to incredibly fast pharmaceutical research for nearly every race that lives on the station. Frequently lampshaded. Apparently he's the only one in the entire galaxy who can do this. Well, maybe the guy before him and the one after him...
 * Opening Narration: Different for each new season (WARNING: spoilers ahoy in this one!).
 * Operation Blank: Operation Sudden Death ("GROPOS").
 * Opt Out: An extra after Sheridan gives a Line in the Sand speech. In the commentary, JMS stated it's unreasonable that no one ever leaves in moments like that, especially in essentially a rebellion.
 * Order Versus Chaos: The whole point of the war between.
 * Ordered Apology: See the entry for Backhanded Apology in the A-H section.
 * Orphaned Punchline:
 * "...and then she said to me, "If I could do that, I wouldn't need an encounter suit!"" - Garibaldi ("Survivors")
 * "...and he says, "Goulash!"" - Londo ("A Voice in the Wilderness")
 * "...That's not my leg, that's my air hose!" - Londo, again.
 * The Other Darrin:
 * Delenn's mentor, Draal, is played by Louis Turenne in the two-parter "A Time in the Wilderness". In all of his subsequent appearance, he is played John Schuck. This is Hand Waved by explaining that Draal has age-regressed as a result of being linked with the Great Machine.
 * Apparently they had a terrible time keeping actresses around to play G'Kar's aide. His first one, Ko'Dath, disappears under mysterious circumstances because Mary Woronov had trouble with the Narn makeup and prosthetics. The same problem drove away the first Na'Toth actress, Susan Kellerman. Julie Caitlin Brown made it through the entire first season (and was awesome) before she, too, succumbed to makeup problems and quit. Her role was given to Mary Kay Adams, who was not up to the task at all, and finally Na'Toth was written out of the story altogether. (However, she is later mentioned as having been captured by the Centauri during the war, and.
 * Our Doors Are Different: The doors on the station are mostly automatic-opening, slide open sideways, and are a sort of lopsided pentagon shape instead of rectangular. Elevator doors are rectangular, but split open on a diagonal.
 * In "The Gathering", the pentagonal doors actually opened on corner hinge, flipping up into the wall butterfly-style. The impracticality of this mechanism on a weekly show likely led to the more conventional side-slide method used thereafter.
 * Our Elves Are Better: The Minbari, who are elegant, refined and more technologically advanced than nearly any other race. With a link to The Fair Folk, they are also quite willing to wipe out an entire species if provoked.
 * Our Showers Are Different:
 * Water conservation is important on the station so only the executive suites and command quarters get showers with running water; everybody else has to make do with "vibe showers".
 * Earth's space ships don't have water showers even in the command quarters; when Captain Sheridan is transferred to Babylon 5, he is seriously happy when he learns his quarters include "a real live honest-to-god shower with running water".
 * The Minbari use a chemical that removes the outermost layer of skin. It does terrible things to hair, as Delenn finds out.
 * Outgrown Such Silly Superstitions: Totally and utterly averted. Every race is religious, although humanity surprises everyone by having so many different faiths (the only other species explicitly stated to have multiple religions is the Narns, and it's implied that they have many, many fewer than Earth).
 * Outgrown Such Silly Superstitions: Totally and utterly averted. Every race is religious, although humanity surprises everyone by having so many different faiths (the only other species explicitly stated to have multiple religions is the Narns, and it's implied that they have many, many fewer than Earth).


 * Outrun the Fireball: Sinclair does this in the Pilot Movie when a high-tech piece of equipment overloads.
 * Londo does this as well, though in his case it's more like "Dive sideways into an elevator to avoid the fireball."
 * Overly Long Name: The actual species name for the Shadows is over one thousand syllables long.

P
"Londo: My shoes are now too tight, and I have forgotten how to dance. Vir: I don't understand. Londo: Nor should you. [Later, when he helps the two young Centauri and they ask why] Londo: Because you are young, and young people should be allowed to dance!"
 * Parenthetical Swearing: "Bester" sounds like "bastard" whenever any station personnel speaks the name.
 * The Password Is Always Swordfish:
 * First averted by Garibaldi, who selects a password "peekaboo" purely on the grounds that nobody would have ever guessed he would use it. And because it would get a big laugh.
 * Later justified, by Sinclair, when he needs to leave a password-protected message behind for Garibaldi. In this case the password had to be something that wouldn't be easily guessable in general, but would be easily guessable by Garibaldi. He settles on "Hello, old friend".
 * Percussive Maintenance: Ivanova trying to access the records of an old exploration vessel in "The Long Dark".
 * Percussive Pickpocket: Happens to Sheridan, where the thief steals the comlink.
 * Jinxo does this to Aldous in Grail.
 * A strange example occurs in Passing Through Gethsemane. A Centauri bumps into Brother Edward as the latter is leaving an elevator. The viewer discovers later that the Centauri was a telepath, and bumped into Brother Edward so he could break the monk's mind block.
 * Percussive Therapy: In frustration, Garibaldi shoots out an elevator's intercom just so he won't have to listen to Sparky yap any more.
 * Perfect Pacifist People: Subverted by the Minbari, who are pacifists only among themselves. And later
 * Person of Mass Destruction:
 * Pet the Dog: Londo Mollari has so many of these that it makes people cry.

"Bo: (Talking about Delenn) I know I'd claw my way out of hell and through three miles of sheer rock to see that smile again!"
 * Phlebotinum Rebel: Jason Ironheart in "Mind War".
 * Pieces of God
 * Pillars of Moral Character: Noted repeatedly is the concept that death is easy, obligations are hard. The Minbari Warrior caste states that they do not fear death, only failure to complete their appointed tasks. Lorien points out that Heroic Sacrifice is easy compared to living in pursuit of a cause. G'Kar defends David Martel's decision to retreat from a hopeless battle because death is a release from obligations. Pretty much every Big Good in the series holds to this.
 * Planet of Hats: Nearly every race. (Well, the Minbari have three types of hats.) Humanity's hat is diversity and community-building.
 * The Plague: The Drafa ("Confessions and Lamentations")
 * Playing with Syringes: The secret Psi-Corp project in "Mind War".
 * Point Defenseless: Utterly averted. The first time we see B5's defense grid fire, they pop two incoming fighters within seconds. Later, we learn that B5's defense grid is considered subpar by EarthForce standards, when they get upgrades.
 * Ships in the B5 setting generally lack Deflector Shields (except those piloted by EldritchAbominations from another dimension subject to different physical laws). Instead, they use their weapons systems to intercept incoming fire directly.
 * Police Brutality: Micheal Garibaldi has many friends from Mars, including an ex-lover of his. When there is fighting ongoing on Mars, it is probably best to take the hint when he asks you to stop talking trash about Marsies. He doesn't lose his temper often, but when he does, it isn't pretty.
 * Political Officer: One gets assigned to babysit Captain Sheridan. She has a rather direct technique for trying to secure his loyalty. She ends up returning to Earth to do damage control after someone finds and leaks evidence that President Clarke may have had something to do with his predecessor's death.
 * Powder Keg Crowd: Following a recurrence of the Drafa virus, all of the Markab aboard B5 explode into a panic. According to Markab lore, Drafa only targets the sinful, resulting in their elders accusing everyone in sight (including Sheridan and co.) of being "unclean".
 * Narn and Centauri crowds during the Narn Centauri War in the second season, and after the end of the war, the frustrated Narn population as a whole, who G'Kar has to work to keep under control.
 * Human crowds aboard the station in the third season, around when everything begins to go completely off the rails due to internal tensions in the Earth Alliance.
 * Power Fist: Trakis's taser glove in "Born to the Purple".
 * The Power of Love: Sheridan's love for Delenn is what gives him the anchor needed for Lorien to bring him back to life, and in fact may be responsible for winning both the Shadow War and the Earth Civil War. A station worker in the 5th season sums it up quite nicely:

"Lyta: Captain...they're pissed!"
 * Power Walk: The intercut between Sheridan and Nightwatch near the conclusion of "Point of No Return". Both sides are gathering their forces to arrest the opposing side's leader.
 * Precision F-Strike: After Sheridan deliberately provokes the Vorlon and Shadow fleets:


 * President Evil: Morgan Clark.
 * Pretext for War: Kalain, alone in his cell, . Kalain hopes that the station will attack and destroy his ship, the Trigati, allowing his disgraced crew to reclaim their honor and restart the Earth-Minbari war in a single stroke.
 * "Previously On...": Used in part two of the two-parter "A Voice in the Wilderness", in certain major arc episodes to remind the audience of previous events that are referenced, as well as the entire fifth season narration (see below).
 * Principles Zealot: The rogue Soul Hunter.
 * Prophecy Twist: Londo's chronic dreams of himself and G'Kar choking each other to death. Twenty years later ("War Without End, Pt. 2"),.
 * Prophetic Ship Names:
 * Icarus.
 * Especially if you recall what happened to the
 * Played with in "Grail". Jinxo stays on Babylon 5 because he believes he carries a curse that will cause the station to blow up the moment he leaves it. At the end of the episode he finally gets up the courage to leave... on a ship called the Marie Celeste.
 * Prop Recycling: In "Babylon Squared", and again in "War Without End", space suits from 2010: The Year We Make Contact were used. They changed their appearance as much as they could, but some people still recognized them, and assumed it was meant as a Shout-Out.
 * Psychic Static: The nursery rhyme variant is used against Bester.
 * Telepaths in general are trained to use this to cloud their own abilities while not actively working.
 * Used by Garibaldi while on the run from several Telepaths.
 * One guy tries to block Lyta by solving math equations in his head.
 * Puny Earthlings: Played straight with regards to a few races' raw physical strength (Minbari, Narn...) compared to humans; but averted in other cases. Minbari come from a planet that is colder than Earth, and temperatures high enough that a human would merely find enormously uncomfortable will kill a Minbari rapidly; also, they become violently deranged when they consume alcohol. The Drazi have the opposite problem; they are far more intolerant of COLD weather than humans are.
 * Puppet King: Cartagia (at first...)
 * Puppeteer Parasite:
 * Used straight with.
 * Subverted in "Exogenesis" by the Vindrizi who purposely seek out the downtrodden, such as Lurkers or the terminally-ill, and take possession of their bodies under consent only. In return for carrying the parasites, the hosts get to share the memories of thousands of lifetimes of the Vindrizi's travel throughout the universe.
 * PsiCop Bester subtly controlling by enhancing the paranoid tendencies of his mind and planting post-hypnotic suggestions; and the PsiCorps being able to plant a second "sleeper" personality into people, something which happened to.
