The Green Lantern Corps
Katma Tui was a Green Lantern, and trainer of new recruits to the Corps. She had a brief, romantic relationship with John Stewart.
- Adaptation Dye-Job: Here, she's orange-skinned. In the comics, she's got magenta skin.
- Costume Evolution: In Unlimited, she took to wearing a custom uniform after her earlier appearances featured her wearing the same GL uniform John wears.
- Green-Skinned Space Babe: Orange-skinned.
- Interspecies Romance: She (a Korugarian) had a brief romance with John (a human).
- Mentor: To most of the other Green Lanterns. John Stewart even compares her to Yoda at one point.
- Ms. Fanservice: In her first appearance, she wears a regular Green Lantern uniform. When she reappears in "The Return", she is wearing a sexier, customized version of the outfit. And in "Hearts and Minds", she dons a rather Stripperific "priestess" outfit.
- Sexy Mentor: To John Stewart.
- Ship Sinking: In the source material, she and John were officially together, but here, it was a brief fling and John ends up pursuing other women, particularly Shayera at the time.
- Shout-Out: Her "priestess" outfit is basically the infamous slave Leia costume in everything but name.
- Stern Teacher: She is not particularly warm or kind when training her students.
- Teacher/Student Romance: It is all but said out loud that she had one with John while training him as a Green Lantern.
Kilowog was a member of the Green Lantern Corps.
- Ace Custom: Interestingly, he is given an upgraded Green Lantern armor uniform when he goes to confront AMAZO, even though GL uniforms are explicitly mental constructs.
- Adaptational Nice Guy: In contrast to most versions of the character, Kilowog is the most kind-hearted of the Corps members shown.
- Art Evolution: He underwent this, as his face got redesigned along with his custom uniform in Unlimitednote and his design in Vs. the Fatal Five is basically a 2-D version of his Green Lantern: The Animated Series design. Even the hologram◊ from the Superman: The Animated Series episode "In Brightest Day" looks a bit different from his JL design.
- Big Eater: Even moreso than the Flash.
- Costume Evolution: In Superman: TAS and JL, he wore the same uniform as Kyle and John did in those series. During his brief appearance in Unlimited, he took to wearing an armored costume, and in Vs. The Fatal Five, he's wearing his Green Lantern: The Animated Series costume.
- The Engineer: His other skill outside of his Green Lantern powers. In "Hearts and Minds", he is able to rapidly construct a carbon bomb with relative ease.
- Extreme Omnivore: At one point, he eats a videotape, proclaiming it to be delicious.
- Impaled with Extreme Prejudice: He is badly impaled by the Emerald Empress during his fight with Validus. Fortunately, none of his vital organs were hurt and he survived, according to Word of God.
- Mythology Gag: His redesign in Vs. The Fatal Five is based off of his design in Green Lantern: The Animated Series and Kevim Michael Richardson even does a Role Reprisal.
- Odd Friendship: With Flash. They bond over their mutual friendship with John Stewart, their wise-cracking personalities, and their love of food.
- Pig Man: Which makes Flash inviting him to a bratwurst cookout all the more hilarious.
- Redemption Earns Life: Notably in "Blackest Night", he was the only member of the Green Lantern Corps to speak up for and defend John Stewart's character during his trial (albeit after some convincing from Hawkgirl). Later in "Hearts and Minds", several of his colleagues are killed in battle while he is spared and would go on to become a semi-regular Recurring Character.
Captain Marvel (Billy Batson)
Captain Marvel was a superhero who protected Fawcett City, and a former member of the Justice League.
- Ascended Fanboy: He openly admits to idolizing the Justice Leaguers (especially Superman) before briefly joining himself.
- Broken Pedestal: Superman's paranoid behavior during Marvel's time on the Justice League makes him lose a lot of respect for someone that he once idolized.
- The Cape: Is arguably an even bigger archetype of this trope than Superman himself, much to the latter's annoyance.
- Manchild: He comes off like this towards the rest of the League sometimes (who are unaware that his secret identity is a child).
- Nice Guy: His cheerful and positive attitude rubs off so warmly on the Justice League that even Batman takes a liking to him.
- Older Alter Ego: Billy and Marvel.
- The Pollyanna: Has a rather sunny and optimistic approach to being a superhero.
- Shock and Awe: He can use the magical lightning he uses to transform himself between Marvel and Billy as a weapon, like when he held down Superman so he could be struck by it.
- Unwitting Pawn: Of a Batman Gambit that Lex Luthor and Cadmus performed on Superman to make him look bad in public.
- Wide-Eyed Idealist: He's far far towards the ideal end of the Sliding Scale of Idealism vs. Cynicism. Justified since he is actually only a young child beneath his superhero exterior.
- What the Hell, Hero?: Delivers a fairly brutal one towards Superman after the latter destroyed Lexor City during their fight. He also announces his resignation from the Justice League in the same speech. Superman is crushed.
Hawkman (Carter Hall)
Hawkman, also known as the archaeologist Carter Hall, is a man who claims that he is the reincarnation of an ancient Thanagarian who became emperor of Egypt and that Shayera's past life was his lover. Well intentioned, but a bit creepy given his obsessive attitude. He dons a pair of artificial wings and Thanagarian battle armor, apparently fighting crime.
- Adaptational Nice Guy: The comic version of Hawkman is an extremely aggressive, bloodthirsty brute of a man, though still heroic. This version is quite mellow and friendly.
- Adventure Archaeologist: His day job is exploring old tombs and evading traps.
- Ancient Astronauts: His past life landed in Egypt, taught them agriculture and started conquering the nearby lands to bring civilization. Without them, Earth probably would not be as advanced as it is today.
- Badass Bookworm: He's just an archaeologist, but when he touches the Absorbicron he decides he's the reincarnation of a Thanagarian, builds some artificial wings for himself and begins fighting crime. He even seems to be pretty good at it, capturing a magician who was giving John trouble.
- The Cloud Cuckoolander Was Right: It is mentioned that he lost much of his credibility in the archaeology field when he began proclaiming his Thanagarian Ancient Astronauts theory and even Hawkgirl thinks he is delusional when he insists that they are the reincarnations of the ancient Thanagarians. Then in "Ancient History", the Shadow Thief reveals that his claims were right all along.
- Crazy Jealous Guy: Subverted. When Shadow Thief tells him to kill his rival Green Lantern, it looks as though he's going to do it. However, Carter simply uses the axe he was given to free John from his restraints.
- Decomposite Character: Turns out he is not Shayera's destined lover reincarnated, GL is. Shayera and Hawkman were married in a previous life and were fond of eachother, but Shayera's true (and secret) love was John (who was also Hawkman's best friend, ouch).
- Driven to Suicide: When Katar Hol realized his advisor has poisoned Past Shayera and John, he committed suicide himself out of grief.
- Flight: He wears a pair of artificial wings strapped to his chest that allow him to fly.
- I Want My Beloved to Be Happy: After discovering the true history between Katar Hol, Chay-Ara Hol, and Bashari, he quickly apologizes to Shayera and leaves, realizing that she is destined to be together with Green Lantern.
- Meaningful Rename: He used to be a man named Joseph Gardner, but when an ancient ship's log showed him his past lives he legally changed his name to Carter Hall, which sounds almost the same as Katar Hol.
- Mr. Fanservice: He's buff as hell and wears tights. Shirts? Never heard of 'em.
- Nice Guy: He may be a stalker, but he actually is a good guy and genuinely heroic.
- Reincarnation: He's probably the reincarnation of an ancient Thananagarian police officer.
- Romantic Runner-Up: A nice guy, but Shayera is also interested in John Stewart. When he learns how the relationship of their past lives ended, he leaves peacefully, telling her he has no intention of getting in their way.
- Reincarnation Romance: Subverted. It's strongly implied that he's right about his past life with Shayera, but the relationship had already fallen apart due to Katar Hol's refusal for intimacy.
- Stalking Is Love: Though he tends to creep some people out, he genuinely loves Shayera and wants what is best for her. When he realizes he's making her uncomfortable he gracefully backs off until she feels she's ready. When it becomes clear she never will be, he gives up. For her part, she ignores that he's an obvious stalker until he starts babbling about reincarnation and seems to think he's at least somewhat attractive.
- Walking Shirtless Scene: Just like in the comics.
- Winged Humanoid: With a pair of artificially constructed wings.
Deadman (Boston Brand)
Deadman, real name Boston Brand, was a wandering spirit.
- Alliterative Name: Boston Brand.
- Back from the Dead: Boston Brand was a circus performer who was murdered during a circus act, and consequently forced to dwell in the Earthly realm as a ghost.
- Barred from the Afterlife: Kinda. He can visit, but he never stick around.
- Demonic Possession: Deadman is capable of possessing any mortal being; upon which he could completely control their actions and be in possession of their memories and powers, while they retain no recollection of the happening.
- Did I Say That Out Loud: In the tie-in comics, when he possesses Wonder Woman again at one point, he comments out loud that he looks hot as Wonder Woman. To everyone else, it looks like Diana is the one who's saying it. He realizes this right afterwards.
- Hollywood New England: Well, his name is Boston and he certainly sports the accent.
- Intangibility: As ghost, Deadman can also pass through physical objects.
- Invisible to Normals: He cannot be visibly perceived by other human beings.
- Meaningful Name: As a ghost, you don't get any more meaningful than "Deadman".
- My God, What Have I Done?: When Devil Ray attempts to shoot Wonder Woman, he quickly possesses Batman, picks up a gun, and shoots Devil Ray, accidentally knocking the latter into electrical wires and killing him. This action is rather traumatic for both him and Batman.
- Roaring Rampage of Revenge: After the Legion destroys the Buddhist Temple he was training at and kills the Master.
- Thou Shalt Not Kill: His memory of his Master's teachings convince him to spare Devil Ray's life. He later unintentionally does it anyway.
- You Killed My Father: His motivation for getting revenge on the Legion of Doom and Devil Ray specifically.
Huntress (Helena Bertinelli)
Formerly the sheltered daughter of a mob boss, she became a vigilante in response to his betrayal and murder. She was inducted along with all the other heroes in the first episode of Unlimited, but after she violated the League's rule about attempting to murder villains, she became a Sixth Ranger who helped out her friends in the League.
- Adaptation Origin Connection: Inverted. She has no connection to Batman or the Batfamily other than the Mythology Gags towards her and Black Canary being members of the Birds of Prey. J'onn is the one who tells her off for attempting to kill a criminal, whereas Batman would've been the one doing it in the source material.
- Adaptational Nice Guy: While still an Anti-Hero, she's more heroic here than in the comics, especially after she resolves her issues with Mandragora.
- All Women Are Lustful: She almost always interacts with the Question in a very suggestive way, and some of those interactions tend to imply sexual fantasies.
- Anti-Hero: A little too 'anti' for the League, especially since her first major appearance involves her trying to murder Mandragora while sleeping in his home. She's half Type III, half Type V.
- Automatic Crossbows: She carried an automatic miniature crossbow that she wielded with incredible ease and accuracy, as well as a retractable bo staff and other equipment used to bypass security measures.
- Badass Biker: Her preferred method of transportation.
- Badass Normal: She is a world class athlete, gymnast and martial artist, capable of disarming and defeating multiple armed opponents (however, she was slightly less skilled than Black Canary).
- Bare Your Midriff: Her costume shows off her toned stomach.
- Battle Couple: With the Question. They casually discuss dating plans while kicking butt.
- Blood Knight: After helping Black Canary shut down Roulette's underground metahuman brawl operation, she goads the former into going a few rounds in the cage themselves, to see who's the better fighter.
- Dark and Troubled Past: Helena Bertinelli was the daughter of Mafia crime boss and mobster Franco Bertinelli. As a child, she saw her mother and father murdered by Steven Mandragora, who lusted for power. This event sparked her desire for revenge as, years later in her adult life, she would train herself to become the costumed vigilante known as the Huntress.
- Dark Is Not Evil: Her vigilante costume is mostly black and purple and while she's an Anti-Hero, she's still on the side of good.
- Deadpan Snarker: Constantly makes snide and sarcastic remarks even on the people she works with, or otherwise needs the help of.
- Early Installment Character-Design Difference: In earlier episodes when she was just The Cameo, her design was different (ex. white eyes instead of showing her eyes).
- Fire-Forged Friends: With Black Canary. The two initially butt heads and view each other as obstacles, but they seem to hang out together after the Mandragora case. Although they spend that time insulting each other, Huntress shows concern when Canary seems to be troubled by personal issues (and the Question lampshades how she seems concerned about her rival despite the two appearing to despise each other) and tries to help her. After Huntress helps Canary break out of Roulette's mind control, the two share a genuine moment before going back to insulting each other and sparring for fun.
- The Friend Nobody Likes: A trait she shares with the Question. She has a considerably poor reputation among members of the League with the last straw involving Mandragora resulting in her membership being revoked. Even Black Canary, probably her closest friend besides the Question, mainly gets into physical fights along side her.
- I Work Alone: She accepts this mentality after being kicked out of the League, turning down Dinah's offer to appeal to the League to reinstate her.
- Leotard of Power: With a great big cut-out in the torso because apparently the regular kind wasn't sexy enough.
- Lonely Together: Implied to be the bedrock of her relationship with the Question. He was the only one who tried to help her resolve her personal vendettas and actually treats her respectfully, mainly because he's also seen as a crazed loner Anti-Hero who doesn't play nice with other members of the League.
- Mafia Princess: Was one of these — and did not know. She finds out the hard way.
- Most Common Super Power: She has a very large bust.
- Ms. Fanservice: Huntress is a very beautiful woman who wears a costume that highlights her voluptuous yet toned body, toned stomach, buxom breasts, long legs, and nice rear end. She doesn't get the amount of in-universe attention that Wonder Woman or Black Canary do, but the camera does develop Male Gaze when she's in an episode.
- Official Couple: Huntress and Question became lovers, and also an unofficial team.
- She-Fu: Well, she is a world-class gymnast.
- Strong Girl, Smart Guy: With the Question, as she acts as the muscle while he mainly does detective work.
- Thou Shalt Not Kill: Tried to avert this, which is why J'onn kicks her out of the League.
- Tsundere: Towards the Question. Between snarking at his sleuthing tendencies, she's also kindly to him in tender moments, even calling him "Baby".
- Violently Protective Girlfriend: Huntress is this for Question. If he's working at a console, you can expect her brutally beating guards into unconsciousness in his defense. When the Question was tortured by Cadmus, she nearly outright murdered his torturer until she was recalled by Superman.
- Vitriolic Best Buds: Originally, she regarded Black Canary as an interfering obstacle; after Canary helped with the Mandragora capture, they reached a rapport.
A group of heroes from a comic that turned out to be based on real-life events in another universe.
- Canon Immigrant: Into other DC material.
- The Chick: Black Siren is into baking cookies and other feminine hobbies that were acceptable in the 1950's and suggests to Hawkgirl (the only female Leaguer in the episode) that they leave the men to talk among themselves while they bake cookies together.
- Deliberate Values Dissonance: The Streak compliments Green Lantern with a You Are a Credit to Your Race and Black Siren embraces the Stay in the Kitchen mentality. It rubs off on our modern day heroes the wrong way, but they understand that this is a byproduct of the Justice Guild being written in the 1950's and don't argue about it.
- Expy: Of the Golden Age Justice Society of America, who don't seem to exist in this continuity since no one brings them up in relation to the Justice Guild nor does anyone act like there was a previous superhero team before the Justice League.
- The Streak is one to Jay Garrick, the first Flash.
- Tom Turbine is a composite character of Superman, the first Hourman, and the first Atom (Al Pratt).
- Green Guardsman is one to Alan Scott, the first Green Lantern.
- Catman is a composite character of Wildcat and Adam West's Batman.
- Black Siren is one to Dinah Drake Lance, the first Black Canary, as well as to Wonder Woman, who was only a secretary to the Justice Society in the Golden Age.
- Heroic Sacrifice: They defeat Ray Thompson to free their world from his psychic illusions, even though they themselves are an illusion that would disappear if Ray were to be incapacitated. They succeed.
- Mythology Gag: Black Siren's secret identity is Donna Vance, similar to the first two Black Canaries' names, Dinah Lance. Catman's secret identity is T. Blake, a reference to the Batman villain Catman, whose secret identity was Thomas Blake. Green Guardsman's secret identity is Scott Mason, referencing Alan Scott, the first Green Lantern.
- Take That!: The show doesn't hesitate to make fun of them for representing values that would be seen as offensive today yet seen as acceptable in the 1950's, like Black Siren embracing the Stay in the Kitchen belief (a Take That, Us to Wonder Woman only being a secretary to the Justice Society back in the Golden Age) and the Streak calling Green Lantern, an African-American man, a "credit to [his] race."
- You Are a Credit to Your Race: The Streak says this to Green Lantern, who is a black man. He does find it offensive, but gets the spirit of the message since they were written from a more racially segregated time.
The Flash (Jay Garrick)
The first Flash. Appears only in the tie-in comics and the Justice League Beyond comic.
- Ascended to a Higher Plane of Existence: He joined the Speed Force with Wally and Bart sometime after Justice League Unlimited.
- The Cameo: His helmet can be seen at the Flash museum in "Flash and Substance".
- Dude, Where's My Respect?: Downplayed. When he is invited to an elementary school as a guest, a disrespectful bratty boy dismisses him as less than the "real" Flash (Wally) and wants to see that one. During the events of the story, Jay gets called away to help the League when Wally gets incapacitated, and the story ends with the "real" Flash lecturing the boy about respecting Jay.
- The Mentor: To some extent to Wally.
- Schrödinger's Canon: As the tie-in comics and the Batman Beyond continuation comic are dubiously canon, it's not clear if he really does exist in the DCAU or not. However, his helmet is seen on display at the Flash museum in "Flash and Substance", so it can be assumed that he does exist.
The Legion of Super-Heroes
The Legion of Super-Heroes
Inspired by the legendary Justice League, the Legion of Super-Heroes is an organization from the 30th century consisting of superpowered teenagers from all across the universe.
- Brainwashed and Crazy: In "Far From Home", the Fatal Five manage to use a mind control device to capture legionnaires and use them in their own personal army.
- The Cameo: Saturn Girl, Cosmic Boy, and Chameleon Boy are the only legionnaires focused on in "New Kids In Town". In "Far From Home", it's just Brainiac 5 and Bouncing Boy. Everyone else is relegated to a brief silent appearance.
Saturn Girl (Imra Ardeen)
A talented telepath from Titan and a founding member of the Legion of Super-Heroes.
- Action Girl: It doesn't take a telepath to figure that out.
Cosmic Boy (Rokk Krinn)
A boy with magnetic powers and a founding member of the Legion of Super-Heroes.
Chameleon Boy (Reep Daggle)
A member of the Durlan species, who are able to transform into anything at will.
A 12th-level intellect Coluan, descended from Brainiac, who had learned how to pass his code down biologically. Though he may share his ancestor's intellect, he has a sense of morality and refuses to follow his ancestors in the path of evil.
- Bald of Awesome: In Justice League Vs. The Fatal Five.
- Early Installment Character-Design Difference: In his cameo in "New Kids In Town", he had a mullet and his eyes were completely white.
- White Sheep: Unlike the original Brainiac and presumably the other three Brainiac descendants, he's a good guy.
A boy with the ability to inflate himself like a ball, granting him superhuman resistance while inflated.
- The Knights Who Say "Squee!": He has a fanboy moment when he meets Supergirl, Green Lantern, and Green Arrow.
- Nice Job Breaking It, Hero!: Upon meeting John, he almost gives away that he'll be the father to Warhawk. John, who already knows due to the events of "The Once and Future Thing" (and since doesn't know if Warhawk will cease to exist now that he knows about him), tells him to shut up before he can finish that sentence.Bouncing Boy: You're the famous John Stewart! Father of--
John: You wanna shut up before you create a time paradox?
Bouncing Boy: Sorry.
- What the Hell, Hero?: Gives one to Brainy for refusing to tell the three heroes that Supergirl may die since history says she never returned from the 31st century.
Star Boy (Thomas Kallor)
A young man with the power of gravity, including altering the mass of any object. He is diagnosed with paranoid schizophrenia, which can only be treated by a 31st century medication.
- Adaptation Relationship Overhaul: In the comics, his girlfriend was Dream Girl. Here, while Dream Girl does make a cameo in Superman: The Animated Series, it's implied that his girlfriend in this continuity is Lightning Lass, who he has some interaction with in the main continuity of the comics. Although, Lightning Lass (or rather Light Lass) and Star Boy are Bash Brothers in the Threeboot continuity of the Legion of Super-Heroes comics, which in that case makes this a Relationship Upgrade.
- Adorkable: He unashamedly asks to have Jessica's chocolate pudding and it's the only thing he has at the fast food restaurant that he and the others go to during the movie.
- Broad Strokes: He is based off of his Pre-Crisis incarnation, who accidentally traveled into the Kingdom Come timeline while trying to time-travel to the present day before reaching the Post-Crisis timeline, in which he checked himself into a sanitarium due to lacking his future-time medication for his schizophrenia. The only major difference is that Thomas accidentally travels back in time to the present day when he tries to prevent the Fatal Five from doing so.
- Cassandra Truth: His ramblings about the Fatal Five and Limelight are initially dismissed as delusions.
- Commonality Connection: He and Jessica bond over being troubled heroes.
- Death by Adaptation: In the comics, after his initial mission in the present day, he continued to stay in the present due to other missions he was assigned. Here, he dies after completing his mission in apprehending the Fatal Five.
- Heroic Sacrifice: He sacrifices himself to restabilize the sun when the Emerald Eye destabilizes it.
- Meaningful Echo: Throughout the movie, he repeatedly states that he knows what he's doing because "I'm a superhero.". At the end, when he sacrifices himself to save the sun, he reassures Jessica that it'll be okay, because "I'm a superhero.".
- Mythology Gag: In the Threeboot continuity of the Legion of Super-Heroes comics, he and the Earth-Prime version of Lightning Lass, Light Lass, are partners. Here, they're implied to be a couple.
- Oh, Crap!: After he travels back to the present day, his medication for his schizophrenia breaks. This is a problem because his medication hasn't been invented yet at this time. As a result, he ends up getting checked in to a mental hospital after causing trouble and he struggles with his mania throughout the story.
- Official Couple: Heavily implied to be in one with Lightning Lass.
- One Steve Limit: As a result of Adaptation Name Change, he shares his first name with the late Thomas Wayne. This was intentional by the writers, as it evoked a sense of familiarity to Batman (like Martha).
- Laser-Guided Amnesia: Due to a combination of crash-landing on Earth while trying to stop the Fatal Five's ship while time-travelling as well as the lack of medication for his manic disorder, he ends up having trouble remembering parts of his mission and that he had powers. It takes the events of the story to jog his memory, and even then, Miss Martian has to probe his mind to get more information.
- Power Incontinence: He has trouble controlling his powers due to his mania, but it's more because he's struggling to function with his mania more than his mania causing his powers to work improperly.
- Sanity Slippage: He undergoes this if he's off his medication, which is what happens in Vs. The Fatal Five when he gets stuck in the present day without it. It turns out that this is very bad, because if he's off his medication too long, then he risks becoming immune to it, thus being permanently stuck in his schizophrenic state. By the time of the main story, it's been ten months since he's been without his meds, but at least he's been in Arkham Asylum. Whether or not that actually helped or if the effect of his medication would've worn off is never revealed due to his death.
- Unperson: Initially, Batman and the authorities have trouble finding records of his existence, since he of course comes from the future.
- You Are Not Alone: He and Jessica help each other cope with their own issues and end up growing close because of this.
Agent King Faraday
A federal agent who often assists the Justice League. He was assigned to provide protection to mob boss Steven Mandragora, who supposedly wanted to leave organized crime, until it was revealed that he was simply biding time to secure to safe passage of his son into the United States. By the final season, he's made an official liaison of the Justice League to the US.
- Expy: Fills a very similar role to Steve Trevor in the comics.
- Friend on the Force: Given how government workers and agents are usually distrustful of the League, it's refreshing to see that he has little problem with them. So long as they don't do what like. Like hitting mob bosses under witness protection, for example.
- Punny Name: King Faraday is a play on "king for a day". Of course, he gets to keep that name forever.
- Shout-Out: Uses the line, "goldbricking yahoos" in "To Another Shore", which is a Nick Fury turn of phrase.
- Why Do You Keep Changing Jobs?: Good luck nailing down what agency he works for. He switches from witness protection (US Marshals) to bodyguarding the Vice President (Secret Service) when not being the JLA's liaison. To be fair, this is a quirk of government agencies in the comics, like APES and the CBI.
A reporter in Central City.
- Adaptation Personality Change: In the comics, Linda was more serious in contrast to Wally's goofiness. Here, she's a fan of him, and ironically, Flash is initially oblivious to her advances due to focusing on a mission.
- First Girl Wins: As far as we know, she's the Flash's first real romance and claims this to Giganta, who's been trying to date Flash ever since the ending of Unlimited. Between the two girls, Flash sticks with Linda.
- Is This Thing Still On?: Thinking that the camera is off, she talks to her camerawoman about how Flash is "like, the entire track team at once". Only after she says that does her camerawoman tell her that the camera was still running, causing her to facepalm in embarrassment.
- Two-Person Love Triangle: According to the Red Justice young reader's book, Wally tried dating her, but she broke up with him when she thought that he wasn't committal.
- Unwitting Instigator of Doom: She brings a pocket mirror to the Flash Museum so she can check her makeup. She wasn't counting on Mirror Master and the other Flash rogues to use it to get the drop on everyone through it.
An American spy stationed in Europe during World War II. When the Justice League went back in time to stop Vandal Savage and change back the course of history, Wonder Woman rescued him from a plummeting plane.
Dr. Tracy Simmons
A physicist for S.T.A.R. Labs.
- Canon Foreigner: She was created for the show.
- Did Not Get the Girl: Played with. Booster spends a large chunk of the episode pining after Dr. Simmons, but after Booster stops the black hole, Skeets detects a rush of attraction from Dr. Simmons towards Booster, but Booster doesn't act on it, saying that only heroes get the girl in the end and having concluded that he isn't a hero. However, Dr. Simmons meets up with him at the end of the episode to ask him on a date herself.
- Gadgeteer Genius: She apparently was the one who was working on the gravity inhibitor ring to secure Dr. Brown's powers.
- Hot Scientist: Booster certainly thinks she is.
- Meganekko: A nice woman and looks cute with the glasses.
- Sexy Spectacles: She also fits this trope for looking hot as well.
- Nice Girl: She cares about her boss and Booster.
- Not That Kind of Doctor: When encountering a women in labor, Booster Gold looks to Dr. Tracy Simmons since "your a doctor." Tracy clarifies that she is a physicist.
- One-Shot Character: She only appears in "The Greatest Story Never Told".
A strange old man guarding a mysterious crystal known as the Heart of Darkness, an Ophidian artifact.
- Anti-Villain: He's trying to guard the Heart of Darkness so that the Ophidians can't possess anyone, but his inability to explain this to everyone due to having gone crazy results in people not listening to him, which predictably results in the opposite of what he's trying to accomplish.
- Fish out of Temporal Water: He's been around since ancient times. Flash gets him to become a commercial spokesman partially to help him adjust to modern society.
- Poor Communication Kills: Since he's gone senile from all those years guarding the Heart of Darkness, people dismiss his hostility as him being crazy and he doesn't bother explaining his actions in a way that the others can understand. When the Heart of Darkness possesses Diana, he attacks her in public, which makes him seem like a villain.
- Spared by the Adaptation: He was killed in the source material.
- What Happened to the Mouse?: What happened to him after "Eclipsed" is unknown. Maybe his acting career took off.
Queen Hippolyta of Themyscira
The Queen of the Amazons and the ruler of Themyscira, as well as the mother of Princess Diana of Themyscira, AKA, Wonder Woman.
- Adaptation Dye-Job: She is perhaps the only instance in DC Comics of Hippolyta being portrayed as a blonde woman instead of raven-haired, despite Diana being raven-haired. This raises the Fridge Logic of where Diana got her hair color... but it's implied that she got it from the similarly raven-haired Hades, who was her mother's ex.
- Nice Job Breaking It, Hero!: The Amazons' heavy matriarchal emphasis results in Aresia wildly taking it as men being a pest that must be destroyed, which could have been prevented if Hippolyta had told her that a man gave up his life to save her and bring her to Themyscira, which she refrained because she didn't think it mattered. By the time Hippolyta tells Aresia this, Aresia has gone too far to care about it anymore.
Princess/Queen Audrey of Kaznia
The princess (later, queen) of Kaznia and the daughter of King Gustav.
A US Army General that serves as a foil to the Justice League in regards to extraterrestrial matters big enough to involve the government. While not fully antagonistic as other generals on the show, he is very concerned about relying too much on Superman or the Justice League. His cynicism often clashes with the League but hes proven right more than once.
- Bald, Black Leader Guy: He's a bald black general.
- The Brigadier: Serves as this for the first two seasons before Cadmus comes into focus.
- Cassandra Truth: In both of his major appearances, he warns against putting too much trust in Supermans ability to save the world unilaterally and the good intentions of the Thanagarians though his superiors ignore his advice. Hes proven right both times.
- The Complainer Is Always Wrong: Subverted.
- Expy: Fills the role of the military leader that distrusts the heroes, not unlike General Hardcastle in Superman: The Animated Series and later Eilling in subsequent seasons though Wells never reaches the level of antagonism that either adopt towards the League.
- Jerkass Has a Point: He criticizes the idea of having Superman deweaponize the worlds militaries, noting theyre putting too much faith in his ability to unilaterally stop global threats. Hes immediately proven right when the world is dangerously ill-prepared for the Imperium invasion.
- Properly Paranoid: He explicitly states he doesnt believe the Thanagarians have Earths best interests at heart. When they turn on the Justice League, he isnt even surprised.
- Small Role, Big Impact: Its his speech post-Imperium invasion that convinces Batman to build the Watchtower and provide the impetus for the Justice League to form.
- Whatever Happened to the Mouse?: Hes never seen again following the Thanagarian invasion, his role on the show being filled by General Eilling and Cadmus in following seasons.
