- City of Adventure
- City of Spies
- Color-Coded for Your Convenience: Each Babylon station was evidently painted in a different color scheme. The first Babylon station was red, Babylon 4 was green, and Babylon 5 was blue. (Babylons 2 and 3 were presumably orange and yellow respectively.)
- Likewise, each section of the station was color-coded. Blue Sector is for administration, docking bays, and Medlabs. Red Sector was the main living area, with markets and housing. Green Sector contained the hydroponic gardens for food and oxygen, as well as recreation areas and the living areas for alien ambassadors. Grey Sector contained all the station's heavy machinery. Inside of Grey Sector is Yellow Sector, which contains the fusion power plant. Finally, there's Brown sector, which contains maintenance and reclamation, but is best known for Downbelow, where B5's transient population lives.
- Government in Exile: Not only served as a human government in exile, but harbored the Narn government in exile, and what was almost but not quite a Minbari government in exile.
- More specifically, Delenn was using it as a base for the Rangers and as an aid to waging war against The Shadows with the Grey Council in abeyance.
- Home Base
- Land of One City: 3-4 seasons
- Not-So-Safe Harbor
- Space Station
- Truce Zone: The whole point of the Babylon Project was to provide a place in neutral territory for all the major races and the League of Non-Aligned Worlds to hash out their differences peacefully, negotiate trade deals and conduct business and the like, ultimately with the goal of avoiding another potentially devastating war like the near-genocidal Earth/Mimbari war. This doesn't stop the station and the space around it being the scene for some rather major violent outbursts, however...
David Mc Intyre AKA "King Arthur"
- The Atoner
- Bash Brothers: Briefly with G'Kar.
- Evolves into Fire-Forged Friends when Mckintyre, having gained closure and resumed his normal identity, leaves the station with G'Kar to help aid and advise the Narn Resistance.
- Bully Hunter: "And they made a very satisfying thump."
- Crouching Moron, Hidden Badass
- Forgiveness: Between him and Delenn. He was actually the man who fired the first shot of the Earth-Minbari war and she was the deciding vote for the Minbari declaration of war.
- I Like Swords
- Just Following Orders: When he fired on the Minbari fleet.
- King in the Mountain: Subverted. He only thought he was King Arthur. Marcus Cole did suggest that he might actually be King Arthur, preserved by the Vorlons, but that was a red herring (though given that this had actually happened just under a year ago with Jack the Ripper, it wasn't outside the realm of possibility.) Franklin points out he wouldn't be speaking modern English if he was.
- Knight in Shining Armor.
- Mysterious Past
- Shell-Shocked Veteran
- Space Marine: in his Mysterious Past
- Trauma-Induced Amnesia
- A Form You Are Comfortable With: The humanoid form he's seen in seems to be a facade, with his real form being an orb of light with tentacles of light.
- Big Good: Helps Younger races to stand against Vorlons and Shadows and convinces the latter two to leave.
- Cool Old Guy
- Deus ex Machina: Quite literally turns out of nowhere and brings Sheridan back to life.
- Energy Being: He is one.
- Figure It Out Yourself: Much like Kosh, his favored way of mentoring is via asking questions, making people figure out their own answers, rather than just giving information - this ultimately symbolized by his own defining question "Why are you here?".
- Greater-Scope Paragon: Lorien recognizes that the feud between the Vorlons and Shadows is hindering the growth of the younger races, and steps in where necessary to help put an end to it. But he also recognizes when it's better to step back and let the younger races Figure It Out Yourself, and doesn't interfere any more than he believes is needed.
- Immortality: Of the unaging but vulnerable to disease or injury kind. His race was born naturally immortal. Their immortality eventually faded away with later generations, except for those who came first like Lorien, and most of the rest of those have since either died off through other means or left the galaxy to explore the rest of the universe.
- Last of His Kind: And the first of his kind. The rest of his kind died by violence or sickness, old age when they became mortal, or left the galaxy.
- The Older Immortal: The first of his species were born immortal and he is the oldest of them and claims to be the first sentient being in the galaxy.
- Precursors: (Lorien has referred to himself as the First One. His race was the one that taught and guided the races that eventually became known as the First Ones.)
- Reasonable Authority Figure: To the First Ones, as he is the first of them. He realises how Vorlons and Shadows are degraded into petty struggles and grew uncaring about really teaching, so he helps Younger races to convince both races stop their war and quit, leaving the galaxy.
- Really 700 Years Old: "Lorien is... older than he looks."
- Sufficiently Advanced Aliens: The biggest one.
- Time Abyss: He claims to be the first sentient being in the galaxy and to remember when the Earth was forming.
- Babylon 5 spends a lot of time setting up the incredible gulf between the "Younger Races" (mankind etc.) and the First Ones. While in most science fiction "the ancients" suffer from rapid villain decay even if made out to be vastly superior technologically at the beginning, in Babylon 5 there is never any question of the Younger Races challenging the First Ones. They can turn planets to rubble by the dozens and wipe away the Younger Races' fleets without even trying very hard... And to Lorien, they are still just barely more than children.
- Time Stands Still: One of his abilities, is to keep people "between moments" between the "tick and the tock (of a clock)". He does talk to talk to a dead/dying Sheridan, before he finally decides to bring him back to life.
- Authority Equals Asskicking
- Everyone Loves Blondes: At least Stephen did.
- Nom de Guerre: "Number One", her real name being kept secret due to her being a Rebel Leader.
- Rebel Leader: Of the Mars Resistance.
- Red Baron: She's better known as "Number One". In fact, her real name wasn't given until Season Five, long after she'd become a major recurring character.
- The Revolution Will Not Be Vilified: She resisted the efforts of the most extremist members to turn the Resistance into the terrorist organization Earthgov wanted them portrayed as.
- The Spymaster: Becomes the head of Interstellar Alliance Covert Intelligence after Garibaldi retires.
- Humanity Is Infectious: He likes the hokey-pokey after hearing it just once.
- Large Ham: Louis Turenne as Draal is rather subtle, but John Schuck loves to project his voice.
- Man in the Machine: Draal replaces the caretaker of the Great Machine of Epsilon 3 which the station is close to.
- The Other Darrin: First played by Louis Turenne, but in future appearances as John Schuck. It is explained that the Great Machine rejuvenated his body.
- Backup Twin: Ten, well nine Zathrases are alive. After one went back in time, the other nine remained in the present. All look the same and all named Zathras. The one who died in the past, "Zathras warn Zathras, but Zathras never listen to Zathras."
- Ditto Aliens
- Ditzy Genius: To whom else could anyone entrust a time machine?
- The EeyoreVery sad life. Probably have very sad death. At least there is symmetry.
- Harsher in Hindsight: One of Zathras's most memorable lines is "[Zathras] probably have very sad death." The actor playing him, Tim Choate, died in a motorcycle accident.
- Lost in Translation: Zathras's attempts to explain that his name is pronounced slightly differently from his brother's, Zathras.
- Metaphorgotten: When trying to explain to Ivanova that they can't possibly run out of time, because time is infinite. He somehow concludes with "This... is wrong tool. Never use this."
- It makes a sort of sense in context. Zathras was searching for the tools and components to fix Sheridan's time stabilizer. Ivanova was being impatient and said that they were "running out of time". Zathras was, in his unique manner, basically replying that time wasn't the major issue; he, a finite being like Ivanova, had finite capabilities, and needed the right tools for the job before he could actually tackle the problem.Cannot run out of time. There is infinite time. You are finite. Zathras is finite. This...is wrong tool.

- Planet of Steves: Zathras is one of many brothers, all named Zathras. One of them claims it's pronounced differently... and then in his demonstration pronounces it exactly the same.
- The Reliable One: Zathras was crucial in the mission to send Babylon 4 to the past, and elected to stay there himself in order to see the mission through, meaning that the outcome of *both* Shadow Wars were due primarily to his efforts.
- Thinking Out Loud: A lot of Zathras's lines come across as him talking to himself at normal conversation level. Perhaps Justified, as his brother Zathras later says that they lead rather lonely lives.
- Third-Person Person
- Affably Evil: Very kind to his employees and other associates, and he even feels compassion for the telepaths he's using as test subjects.
- Corrupt Corporate Executive: Of Edgars Industries, a major pharmaceutical company.
- Heel Realization: The hesitation he says with the "telepath problem" is an Actor Allusion as well as a reference to Word of God. Edgars is Jewish according to JMS and realized what he was saying, only to continue.
- He Who Must Not Be Seen: For his first few appearances, only his voice was heard. He didn't actually appear onscreen until most of the way through season 4.
- I Did What I Had to Do: He believes the development of the telepath virus (and its antidote) is necessary for "mundanes" to have a fighting chance in the telepath war he sees coming.
- Villain Has a Point: While his actions are extreme and unethical, even the heroes like Sheridan believe Edgars was right about the coming telepath war.
- Well-Intentioned Extremist: He became the influential head of a pharmaceutical Mega-Corp solely to accomplish the creation of a virus (and corresponding antidote) exclusively fatal to telepaths. He does this not For the Evulz or even out of a sense of Fantastic Racism, but because he knows a war with telepaths is inevitable and wants to give mundanes a fighting chance. He doesn't even like taking the steps he feels he has to take, and tries to lessen the suffering of those he's testing his drugs on as much as possible. He himself realizes the historical parallels, but still takes his actions because he deems them necessary.
- Deadpan Snarker: Snarks beautifully, and at one point manages to silence Sheridan with an eyebrow.
- Good Shepherd: Brother Theodore is a genuinely devout and caring man, who tends to his flock well.
- Vitriolic Best Buds: With a Baptist minister who visits Babylon 5 for an ecumenical conference. The subdued and contemplative Brother Theodore snarks habitually at his loud, ebullient colleague, but the two otherwise seem to get on fairly well.
- Combat Pragmatist: They are badly outmatched in any fight with Earth Force. Thus, they prefer hit-and-fade attacks against soft targets such as merchant ships, and will only fight Earth Force units if they have no other choice or if they have overwhelming numbers.
- Curb-Stomp Battle: The first time the Shadows make an appearance.
- Most times that we ever see them get cornered into a fight with Earth Force crews. The Starfury is shown to be far superior in pretty much every aspect to their ships. Word of God is that the Raiders, unlike the Starfuries, are built to maneuver in atmosphere as well as space, while the standard Starfury was built specifically for space.
- Gunship Rescue: Invoked twice, when a larger ship is brought in to reinforce them or to help them escape. Both ships are destroyed or disabled soon after.
- Space Pirates
- Starter Villain / Disc-One Final Boss: While they appear a COUPLE of times afterwards, they stop being a major threat after the Shadows appear.
- Their last expedition was into Minbari space. We tracked them back to their homeworld...and made sure they understood the depth of their mistake.
Aliens who kidnap others in order to experiment on them.
